Early Cardiac Metastasis From Squamous Cell Carcinoma Of The Tongue In 2 Patients, Jean Onwuchekwa, Jose Banchs

The Texas Heart Institute Journal

Cardiac metastasis from primary tumors is rare. Cardiac metastasis from squamous cell carcinoma of the tongue is rare; in the English-language medical literature, we read of only 4 patients with this condition. Here, we discuss the cases of 2 such patients who presented at our institution only a few months apart. In both, with the use of 2-dimensional echocardiography, we incidentally found cardiac metastasis from squamous cell carcinoma of the tongue. Resection of the cardiac masses was precluded. These cases illustrate the usefulness of early cardiac evaluation with 2-dimensional echocardiography in patients with head and neck cancer and known metastatic …

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 …

Peripartum Cardiomyopathy: A Review, Anirban Bhattacharyya, Sukhdeep Singh Basra, Priyanka Sen, Biswajit Kar

The Texas Heart Institute Journal

Peripartum cardiomyopathy is idiopathic heart failure occurring in the absence of any determinable heart disease during the last month of pregnancy or the first 5 months postpartum. The incidence varies worldwide but is high in developing nations; the cause of the disease might be a combination of environmental and genetic factors. Diagnostic echocardiographic criteria include left ventricular ejection fraction2.7 cm/m(2). Electrocardiography, magnetic resonance imaging, endomyocardial biopsy, and cardiac catheterization aid in the diagnosis and management of peripartum cardiomyopathy. Cardiac protein assays can also be useful, as suggested by reports of high levels of NT-proBNP, cardiac troponin, tumor necrosis factor-α, interleukin-6, …

Hypoplastic Right-Heart Syndrome Presenting As Multiple Miscarriages, Chadi Dib, Philip A Araoz, Norman P Davies, Joseph A Dearani, Naser M Ammash

The Texas Heart Institute Journal

Reversible causes of miscarriage are many, but they affect only 1% of women who are trying to conceive. Herein, we describe the case of a 23-year-old woman who presented for evaluation of repeated miscarriages and was found to have hypoxemia and erythrocytosis. Further evaluation revealed hypoplastic right-heart syndrome with an intracardiac shunt. She underwent hybrid repair with pulmonary valve balloon valvuloplasty, followed by surgery to perform atrial septal defect closure and a Glenn anastomosis. The erythrocytosis and hypoxemia resolved, and she was able to conceive and deliver a healthy baby at term 2 years later.

This is a unique case …

Coronary Arteriovenous Fistulae: The Complexity Of Coronary Artery-To-Coronary Sinus Connections, Todd L Kiefer, Anna Lisa Crowley, James Jaggers, J Kevin Harrison

The Texas Heart Institute Journal

Coronary artery fistulae are a rare cardiovascular anomaly. Even less common are multiple fistulae involving more than 1 coronary artery. Herein we report the case of a 47-year-old woman who had fistulae from both the right coronary and left circumflex coronary arteries draining into the coronary sinus. These lesions we attempted to close percutaneously but subsequently closed surgically. We discuss diagnostic imaging approaches, along with closure indications, closure options, and outcomes.

Constrictive Pericarditis Treated By Surgery, Alireza A Ghavidel, Maziar Gholampour, Majid Kyavar, Yalda Mirmesdagh, Mohammad-Bagher Tabatabaie

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), …

Carotid Artery Stenting Versus Endarterectomy: A Systematic Review, Amir Gahremanpour, Emerson C Perin, Guilherme Silva

The Texas Heart Institute Journal

For about 2 decades, investigators have been comparing carotid endarterectomy with carotid artery stenting in regard to their effectiveness and safety in treating carotid artery stenosis. We conducted a systematic review to summarize and appraise the available evidence provided by randomized trials, meta-analyses, and registries comparing the clinical outcomes of the 2 procedures. We searched the MEDLINE, SciVerse Scopus, and Cochrane databases and the bibliographies of pertinent textbooks and articles to identify these studies.

The results of clinical trials and, consequently, the meta-analyses of those trials produced conflicting results regarding the comparative effectiveness and safety of carotid endarterectomy and carotid …

Apical Hypertrophic Cardiomyopathy: Preliminary Attempt At Palliation With Use Of Subselective Alcohol Ablation, Paolo Angelini, Carlo Uribe, Jorge Monge, Jorge M Escobar, Eduardo Hernandez-Vila

The Texas Heart Institute Journal

We report a case of severe apical hypertrophic cardiomyopathy in order to discuss the nature of this unusual condition and the possibility of using selective alcohol ablation to effectively treat symptomatic hypertrophic cardiomyopathy that presents with apical aneurysm. A 73-year-old woman with severe, progressive dyspnea and intermittent chest pain was found to have localized left ventricular apical dyskinesia distal to an obstructive mid-distal muscular ring. The ring caused total systolic obliteration of the apical left ventricular cavity. Apical cavity pressure was extremely high, up to 330 mmHg-200 mmHg above that in the main left ventricular cavity. Because of the danger …

Mid-Aortic Syndrome In A 3-Year-Old Girl Successfully Treated By Aorto-Aortic Grafting And Renal Artery Implantation Into The Graft, Tanja Kersnik Levart, Tomislav Klokocovnik

The Texas Heart Institute Journal

Mid-aortic syndrome, an uncommon acquired or congenital condition characterized by segmental narrowing of the abdominal or distal descending thoracic aorta, is frequently accompanied by ostial stenosis of the aorta's branches. If left untreated, it can result in life-threatening complications secondary to severe hypertension.

We report the case of a 3-year-old girl with congenital mid-aortic syndrome, who was diagnosed by chance in the course of a viral illness, and whose high blood pressure values were first dismissed as inaccurate. Attempts to achieve medical or endovascular control of her hypertension were unsuccessful. She was thereafter successfully treated by aorto–aortic bypass grafting, resection …

Transcatheter Retrieval And Repositioning Of Embolized Stent From The Right Ventricle In An Infant, Daisuke Kobayashi, Harinder R Singh, Daniel R Turner, Thomas J Forbes, Srinath T Gowda

The Texas Heart Institute Journal

Intracardiac stent embolization is a challenging complication in a small infant. A Palmaz stent was placed across the atrial septum in a 3-month-old boy to relieve symptoms of right-side heart failure. On routine chest radiography one week later, the stent was found to have embolized into the right ventricle. The stent was retrieved and repositioned by means of transcatheter technique, without subsequent complications. We found this method to be a viable alternative to surgery in a high-risk infant. To our knowledge, this is the first report of the successful transcatheter retrieval and repositioning of an expandable intravascular stent from an …

Management Of Intra-Aortic Balloon Pump Entrapment: A Case Report And Review Of The Literature, Gerard J Fitzmaurice, Anton Collins, Haralambos Parissis

The Texas Heart Institute Journal

An intra-aortic balloon pump is one of the most valuable tools in the cardiac surgeon's armament to assist in the management of the failing heart. Despite its widespread use, there are associated risks and complications, one of which is balloon rupture with associated entrapment. Numerous approaches for dealing with this complication have been described; here we review the previous experience with intra-aortic balloon pump entrapment and discuss potential management, with particular reference to a recent case of our own.
