Coronary Artery Diameter Related To Calcium Scores And Coronary Risk Factors As Measured With Multidetector Computed Tomography: A Substudy Of The Accuracy Trial, Yasmin S Hamirani, Khurram Nasir, Emil Avanes, Jigar Kadakia, Matthew J Budoff

The Texas Heart Institute Journal

Arterial remodeling, an early change of atherosclerosis, can cause dilated arterial diameter. We measured coronary artery diameter with use of noncontrast 64-slice multidetector computed tomography (MDCT), and studied its association with coronary artery calcium levels and traditional coronary risk factors.

We included 140 patients from the ACCURACY trial whose noncontrast MDCT images showed measurable coronary arteries. Using 3 measurements of left main coronary artery (LMCA) and right coronary artery (RCA) diameters within 3 mm of the ostium, we associated the results with traditional coronary risk factors and calcium scores.

The prevalence of LMCA and RCA calcium was 22% and 51%, …

Perventricular Device Closure Of Residual Muscular Ventricular Septal Defects After Repair Of Complex Congenital Heart Defects In Pediatric Patients, Da Zhu, Kaiyu Tao, Qi An, Shuhua Luo, Changping Gan, Ke Lin

The Texas Heart Institute Journal

Residual muscular ventricular septal defects are surgical challenges, especially after the repair of complex congenital heart defects. We investigated perventricular device closure as a salvage technique in pediatric patients who had postoperative residual muscular ventricular septal defects.

From February 2009 through June 2011, 14 pediatric patients at our hospital had residual muscular ventricular septal defects after undergoing surgical repair of complex congenital heart defects. Ten patients met our criteria for perventricular device closure of the residual defects: significant left-to-right shunting (Qp/Qs >1.5) or substantial hemodynamic instability (a defect ≥2 mm in size). The patients' mean age was 20.4 ± 13.5 …

Two Cases Of Bezold-Jarisch Reflex Induced By Intra-Arterial Nitroglycerin In Critical Left Main Coronary Artery Stenosis, Sachin P Shah, Sergio Waxman

The Texas Heart Institute Journal

The Bezold-Jarisch reflex, a well-described phenomenon, occurs upon the stimulation of intracardiac mechanoreceptors and is mediated by vagal afferent nerve fibers. Several factors can sensitize the cardiovascular system to develop this reflex, including acute myocardial ischemia, natriuretic peptides, and, rarely, nitroglycerin administration in the setting of acute myocardial infarction. The development of the Bezold-Jarisch reflex in the presence of severe coronary artery stenosis, specifically left main coronary artery stenosis, has not been described. We report 2 cases of patients who underwent elective coronary angiography and were given intra-arterial nitroglycerin during radial sheath insertion to reduce radial artery spasm. In both …

Feasibility Of Temporary Biventricular Pacing After Off-Pump Coronary Artery Bypass Grafting In Patients With Reduced Left Ventricular Function, Daniel Y Wang, Lauren A Kelly, Marc E Richmond, T Alexander Quinn, Bin Cheng, Michelle D Spotnitz, Santos E Cabreriza, Yoshifumi Naka, Allan S Stewart, Craig R Smith, Henry M Spotnitz

The Texas Heart Institute Journal

In selected patients undergoing cardiac surgery, our research group previously showed that optimized temporary biventricular pacing can increase cardiac output one hour after weaning from cardiopulmonary bypass. Whether pacing is effective after beating-heart surgery is unknown. Accordingly, in this study we examined the feasibility of temporary biventricular pacing after off-pump coronary artery bypass grafting.

The effects of optimized pacing on cardiac output were measured with an electromagnetic aortic flow probe at the conclusion of surgery in 5 patients with a preoperative mean left ventricular ejection fraction of 0.26 (range, 0.15–0.35). Atrioventricular (7) and interventricular (9) delay settings were optimized in …

Preoperative Statin Therapy In Cardiac Surgery Is More Effective In Patients Who Display Preoperative Activation Of The Inflammatory System, José Martínez-Comendador, José Rubio Alvarez, Juan Sierra, Elvis Teijeira, Belén Adrio

The Texas Heart Institute Journal

We sought to determine whether preoperative statin treatment is more effective in reducing, after cardiac surgery with cardiopulmonary bypass, systemic inflammatory response and myocardial damage markers in patients who have elevated preoperative interleukin-6 levels than in patients who have normal preoperative interleukin-6 levels.

The study involved a prospective cohort of 164 patients who underwent coronary and valvular surgery with cardiopulmonary bypass. There were 2 study groups: group A (n = 60), patients with elevated preoperative interleukin-6 levels; and group B (n = 104), patients with normal preoperative interleukin-6 levels. Each group was subdivided according to whether patients were (group 1) …

Inverted Takotsubo Cardiomyopathy And The Fundamental Diagnostic Role Of Echocardiography, Arantza Manzanal, Lara Ruiz, Jose Madrazo, Majesh Makan, Julio Perez

The Texas Heart Institute Journal

Takotsubo cardiomyopathy is characterized by the development of transient focal wall-motion abnormalities that involve the apical and midventricular segments, in the absence of obstructive coronary artery disease. A variant, inverted takotsubo cardiomyopathy, was described in 2010. We report 3 cases in which each patient's transthoracic echocardiogram revealed the characteristic basal and midventricular segmental akinesis of this variant. This pattern is not associated with coronary artery distribution, and it therefore can be differentiated from coronary artery disease with the use of echocardiography, by evaluating the distribution and temporal changes of akinetic areas.

Osteosarcoma Tumor Thrombus: A Case Report With A Review Of The Literature, Pournima Navalkele, Sarah M Jones, Jason K Jones, Jorge D Salazar, Patrick C Toy, Rathi V Iyer, Betty Herrington

The Texas Heart Institute Journal

Tumor thrombus arising from osteosarcoma is rare. We report the case of a 20-year-old man with proximal humerus osteosarcoma, accompanied by an extensive intravascular tumor thrombus extending into the heart. Our review of the literature found 14 previous reports on osteosarcoma with tumor thrombus. The combination of positron emission tomography and computed tomography is very useful in differentiating tumor thrombus from vascular thrombus, thereby avoiding unnecessary anticoagulation therapy. This same imaging combination can also be used to evaluate the response to treatment. Surgical resection of the tumor thrombus is highly recommended. The effect of tumor thrombus on survival is still …

Endovascular Treatment Of Acute Type B Dissection Complicating Aortic Coarctation, Seyed Ebrahim Kassaian, Kyomars Abbasi, Mehdi Mousavi, Mohammad Sahebjam

The Texas Heart Institute Journal

Surgical treatment poses a high risk to patients with concomitant aortic coarctation and dissection, and an interventional approach could be an alternative. We describe the case of a 52-year-old man with a long history of untreated hypertension and aortic coarctation who emergently presented at our institution with an acute Stanford type B dissection. The patient's elevated serum creatinine level, perfusion deficit in the right lower limb, and hypertension did not respond to medical therapy, and he did not consent to surgery. By endovascular means, we used a self-expandable stent-graft to cover the entry point of the dissection; then, we deployed …

Preventing Sudden Cardiac Death In Athletes: In Search Of Evidence-Based, Cost-Effective Screening, Paolo Angelini, Mladen I Vidovich, Christine E Lawless, Macarthur A Elayda, J Alberto Lopez, Dwayne Wolf, James T Willerson

The Texas Heart Institute Journal

Sudden cardiac death in athletes is a recurrent phenomenon at sporting events and during training. Recent studies have associated sudden cardiac death with such cardiovascular conditions as coronary artery anomalies, cardiomyopathies, and electrocardiographic abnormalities, most of which are screenable with modern imaging techniques. We recently inaugurated the Center for Coronary Artery Anomalies at the Texas Heart Institute, which is dedicated to preventing sudden cardiac death in the young and investigating coronary artery anomalies. There, we are conducting 2 cross-sectional studies intended to firmly establish and quantify, in a large group of individuals from a general population, risk factors for sudden …

Cardiovascular Disease In Late Survivors Of Tetralogy Of Fallot: A Tertiary Care Center Experience, Elisa Bradley, Jeff Parker, Eric Novak, Philip Ludbrook, Joseph Billadello, Ari Cedars

The Texas Heart Institute Journal

Patients with tetralogy of Fallot can survive to late adulthood; however, there are few data on cardiovascular outcomes in this population. We conducted a single-center retrospective analysis of cardiovascular outcomes and risk factors in 208 patients with tetralogy of Fallot to better evaluate the burden of cardiovascular disease in this group. Descriptive statistics were used to determine the prevalence of relevant cardiovascular risk factors and outcomes, including a composite analysis of cardiovascular disease. Rates and mean values from the American Heart Association 2011 Heart Disease and Stroke Statistics Update were used as population estimates for comparison.

In tetralogy of Fallot …

Cor Triatriatum Sinister In A 43-Year-Old Man With Syncope, Janet L Eichholz, Samer S Hodroge, Jerry J Crook, John W Mack, Dale C Wortham

The Texas Heart Institute Journal

Cor triatriatum sinister, a congenital cardiac anomaly involving a fibromuscular membrane that partitions the left atrium into 2 chambers, has been reported in only 0.1% to 0.4% of patients with congenital heart disease. The posterosuperior chamber receives blood from the pulmonary veins, and the anteroinferior chamber contains the left atrial appendage and mitral valve orifice. Most patients are diagnosed with the condition in infancy or childhood; adult cases are rare. We describe a case of cor triatriatum sinister in a 43-year-old man whose only presenting symptom was recurrent syncope. He underwent corrective resection of the membrane and was asymptomatic thereafter. …

Low Serum Triglyceride Levels As Predictors Of Cardiac Death In Heart Failure Patients, Guliz Kozdag, Gokhan Ertas, Ender Emre, Yasar Akay, Umut Celikyurt, Tayfun Sahin, Gozde Gorur, Kurtulus Karauzum, Irem Yilmaz, Dilek Ural, Mira Sarsekeyeva

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Clinical trials often rely on echocardiographic measures of left ventricular size and function as surrogate end points. However, the quantitative impact of factors that affect the reproducibility of these measures is unknown. To address this issue, the National Heart, Lung, and Blood Institute-funded Pediatric Heart Network designed a longitudinal observational study of children with known or suspected dilated cardiomyopathy aged 0 to 22 years from eight pediatric clinical centers.

METHODS: Clinical data were collected together with 150 echocardiographic indices of left ventricular size and function. Separate observers performed duplicate echocardiographic imaging. Multiple observers performed measurements from three cardiac cycles …

Culprit-Vessel Percutaneous Coronary Intervention Followed By Contralateral Angiography Versus Complete Angiography In Patients With St-Elevation Myocardial Infarction, Chadi Dib, Elias B Hanna, Muhammad A Chaudhry, Thomas A Hennebry, Stavros Stavrakis, Mazen S Abu-Fadel

The Texas Heart Institute Journal

In patients with ST-elevation myocardial infarction, delay in door-to-balloon time strongly increases mortality rates. To our knowledge, no randomized studies to date have focused on reducing delays within the catheterization laboratory.

We performed a retrospective analysis of all patients who presented with ST-elevation myocardial infarction at our institution from July 2006 through June 2010, looking primarily at time differences between percutaneous coronary intervention in the culprit vessel on the basis of ECG criteria, followed by contralateral angiography (Group 1), versus complete coronary angiography followed by culprit-vessel percutaneous intervention (Group 2).

There were 49 patients in Group 1 and 57 patients …

Nitinol Thermoreactive Clips For Secondary Sternal Closure In Cases Of Noninfective Sternal Dehiscence, Arif Gucu, Faruk Toktas, Cuneyt Eris, Yusuf Ata, Tamer Turk

The Texas Heart Institute Journal

Postoperative sternal dehiscence is a potentially catastrophic sequela to median sternotomy that can cause not only chest-wall discomfort and pulmonary dysfunction but infection, both superficial and mediastinal. Nitinol thermoreactive clips use a novel material in the treatment of sternal dehiscence. We sought to determine whether the use of these clips is an effective remedy for noninfective sternal dehiscence.

From January 2008 through December 2011, we retrospectively studied the data on 10 patients whose sternums had been closed with nitinol thermoreactive clips after the development of noninfective sternal dehiscence. Diagnosis was made on the bases of clinical criteria, chest radiography, and …

Does The Expression Of Transforming Growth Factor Β-1: Affect The Outcome Of The Radiofrequency Modified Maze Procedure In Patients With Rheumatic Atrial Fibrillation?, Wei Wang, Lei Liu, Yuan Li, Sheng-Shou Hu, Yun-Hu Song, Xin Wang

The Texas Heart Institute Journal

We investigated whether the expression of transforming growth factor β-1 in the left atrial appendage affected the outcome of the radiofrequency modified maze procedure in patients with rheumatic valve disease and long-standing persistent atrial fibrillation.

Messenger RNA and protein expression of transforming growth factor β-1 and volume fractions of collagen types I and III were measured in 80 patients with rheumatic valve atrial fibrillation who underwent valve surgery with the radiofrequency modified maze procedure; the same was done in a control group of 20 patients with rheumatic valve disease and sinus rhythm who underwent valve surgery alone.

At 6 months' …

Extreme Thrombocytosis And Cardiovascular Surgery: Risks And Management, Ethan A Natelson

The Texas Heart Institute Journal

Extreme thrombocytosis is a major risk factor for excessive bleeding and for thrombosis, either of which can complicate cardiovascular surgical and interventional procedures. Extreme thrombocytosis can also cause an unusual syndrome, erythromelalgia, that results in a type of chronic microvascular occlusive arterial disease. We present the differential diagnosis of conditions that may lead to extreme thrombocytosis, 3 cases (each of which illustrates a different potential complication), and a review of the pertinent medical literature. Correcting excessive thrombocytosis is typically not difficult, whether electively or acutely, and effective therapy usually controls thrombosis and excessive hemorrhage post-procedurally.

Long-Term Results Of Aortic Banding For Complex Infrarenal Neck Anatomy And Type I Endoleak After Endovascular Abdominal Aortic Aneurysm Repair, Zvonimir Krajcer, Kathryn G Dougherty, Igor D Gregoric

The Texas Heart Institute Journal

For many patients with abdominal aortic aneurysm, unsuitable anatomy of the infrarenal aortic neck precludes endovascular aortic aneurysm repair or causes type I endoleak after the procedure. In an attempt to overcome these challenges, we retrospectively examined the usefulness of aortic banding as an adjunctive procedure to endovascular repair in 8 patients who had an abdominal aortic aneurysm with a complex infrarenal aortic neck. The procedures were performed with the patients under general anesthesia and involved making an 8-cm upper-midline laparotomy incision to expose the aneurysmal aorta. Three patients underwent aortic banding before endovascular repair; the other 5 underwent banding …

Potential Role Of Plasma Myeloperoxidase Level In Predicting Long-Term Outcome Of Acute Myocardial Infarction, Mehmet Gungor Kaya, Ridvan Yalcin, Kaan Okyay, Fatih Poyraz, Nilufer Bayraktar, Hatice Pasaoglu, Bulent Boyaci, Atiye Cengel

The Texas Heart Institute Journal

We investigated the prognostic importance of plasma myeloperoxidase levels in patients with ST-elevation myocardial infarction (STEMI) at long-term follow-up, and we analyzed the correlations between plasma myeloperoxidase levels and other biochemical values.

We evaluated 73 consecutive patients (56 men; mean age, 56 ±11 yr) diagnosed with acute STEMI and 46 age- and sex-matched healthy control participants. Patients were divided into 2 groups according to the median myeloperoxidase level (Group 1: plasma myeloperoxidase ≤68 ng/mL; and Group 2: plasma myeloperoxidase >68 ng/mL). Patients were monitored for the occurrence of major adverse cardiovascular events (MACE), which were defined as cardiac death; reinfarction; …

Eptifibatide-Induced Thrombocytopenia: With Thrombosis And Disseminated Intravascular Coagulation Immediately After Left Main Coronary Artery Percutaneous Coronary Angioplasty, Michael W Tempelhof, Keith H Benzuly, Dan Fintel, Marc Z Krichavsky

The Texas Heart Institute Journal

Early clinical trials of eptifibatide did not show a significant association between eptifibatide and the development of thrombocytopenia, thrombosis, or disseminated intravascular coagulation. However, more recent literature has suggested a significant association between eptifibatide and the development of thrombocytopenia and thrombosis. Although the true incidence and the pathophysiology of these associations are unknown, the development of these events can be life-threatening. Herein, we describe the case of a patient who experienced acute onset of profound thrombocytopenia, developing thrombosis, pulmonary emboli, and disseminated intravascular coagulation. This paper adds to the few previous reports of cases that suggested an association between thrombocytopenia, …

Accuracy Of Automated Attenuation-Based 3-Dimensional Segmentation: In The Analysis Of Left Ventricular Function Compared With Magnetic Resonance Imaging, Harald Brodoefel, Ilias Tsiflikas, Ulrich Kramer, Nina Lang, Anja Reimann, Christoph Burgstahler, Claus D Claussen, Martin Heuschmid

The Texas Heart Institute Journal

We evaluated attenuation-based 3-dimensional segmentation for the analysis of left ventricular function, using as our standard of reference magnetic resonance imaging and dual-source computed tomography with traditional short-axis planimetry.

Twenty patients with known or suspected coronary artery disease were examined prospectively. In all magnetic resonance and computed tomographic datasets, global functional values were determined by 2-dimensional planimetry. Computed tomographic scans were further evaluated by automated 3-dimensional segmentation, and the results were compared by Pearson correlation and Bland-Altman analysis.

Agreement between magnetic resonance imaging and dual-source computed tomographic 2-dimensional planimetry was good for all values (end-diastolic volume, bias= −4.2, r=0.99; end-systolic …

The Texas Heart Institute Journal

We reviewed the records of 45 patients (mean age, 46.6 ± 14.9 yr; range, 21–84 yr) with a diagnosis of constrictive pericarditis who had undergone pericardiectomy from 1994 through 2006. Preoperatively, 2 of the patients (4.4%) were in New York Heart Association (NYHA) functional class I, 20 (44.4%) in class II, 22 (48.9%) in class III, and 1 (2.2%) in class IV. Pericardial calcification was detected in 20% of plain chest radiographs. Constrictive pericarditis was caused by tuberculosis in 22.2%, chronic renal failure in 8.9%, a history of sternotomy in 4.4%, and malignancy in 4.4%. The cause was idiopathic in …

Acute Promyelocytic Leukemia As A Cause Of Intracoronary Drug-Eluting-Stent Thrombosis, Zaven Sargsyan, Christopher Higgins, Sanda Alexandrescu, David A Ott, Surendra K Jain

The Texas Heart Institute Journal

Stent thrombosis is a potentially lethal complication of percutaneous coronary intervention. We describe the case of a 51-year-old man who presented with acute anterior ST-segment-elevation myocardial infarction and underwent successful percutaneous transluminal coronary angioplasty and placement of 3 drug-eluting stents in the left anterior descending coronary artery. Despite receiving dual antiplatelet therapy, the patient presented a week later with a non-ST-segment-elevation myocardial infarction and was found to have nonocclusive thrombosis of the left anterior descending coronary artery stents and his ostial left main and left circumflex coronary arteries. Subsequently, bone marrow biopsy analysis indicated that the patient had acute myelogenous …

Restoration Of Microcirculatory Patency After Myocardial Infarction: Results Of Current Coronary Interventional Strategies And Techniques, Marlos R Fernandes, R David Fish, John Canales, Jonathan Aliota, Guilherme V Silva, Emerson C Perin, Macarthur A Elayda, James M Wilson

The Texas Heart Institute Journal

We sought to evaluate the restoration of microcirculatory patency after primary percutaneous coronary intervention (PCI) in an unselected cohort of patients at a tertiary center.

We retrospectively evaluated distributions of the Thrombolysis in Myocardial Infarction (TIMI) myocardial perfusion grade (TMPG) and the myocardial blush grade (MBG) in all primary PCI procedures performed at our institution during 2008. We defined optimal microvascular perfusion as simultaneous TMPG 3 and MBG 3 at procedure's end.

Ninety-nine patients (mean age, 61.5 ± 12.7 yr; 64 men) underwent primary PCI. Microvascular perfusion was optimal in 69 patients (69.7%) and was associated with lower peaks of …

Cellular Retrograde Cardiomyoplasty And Relaxin Therapy For Postischemic Myocardial Repair In A Rat Model, Gabriella Di Lascio, Guy Harmelin, Mattia Targetti, Cristina Nanni, Giacomo Bianchi, Tommaso Gasbarri, Sandro Gelsomino, Daniele Bani, Sandra Zecchi Orlandini, Massimo Bonacchi

The Texas Heart Institute Journal

We sought to determine whether skeletal myoblasts, wild-type or engineered to express relaxin, might improve myocardial viability and performance in a rat model of chronic myocardial infarction. Our purpose was to investigate a potential new therapy for heart failure.

From October 2005 through September 2009, we surgically induced acute myocardial infarction in 80 male Wistar rats. Thirty days after surgery, the rats underwent reoperation for the retrograde coronary venous infusion of skeletal myoblasts, relaxin, or both. The animals were randomly assigned to 4 experimental groups: R1 (the control group, which underwent saline-solution infusion), R2 (systemic relaxin therapy), R3 (myoblast infusion), …
