Traumatic Aortic Transection Repair With Distal Perfusion - Single Center Experience, Hina Inam, Syed Shahabuddin, Aiman Tariq, Sumera Inam, Saulat Fatimi

Section of Cardiothoracic Surgery

Blunt aortic injury is associated with significant mortality. A large number of patients lose their lives before reaching the hospital, those who survive half die within a day. Isthmus is the commonest site of aortic injury. Aortic injury is usually associated with other injuries of the body hence a multidisciplinary approach is required. For aortic transection the treatment options have evolved from proximal and distal aortic cross clamping and repair with distal perfusion technique using shunt or partial heart bypass (extracorporeal circulation) to endovascular stenting depending upon the available facilities andexpertise. Distal perfusion technique helps in avoiding paraplegia. We present …

Iatrogenic Trauma Following Percutaneous And Minimally Invasive Surgical Interventions, M Hammad Ather, Tashfeen Ahmad, Shabbir Akhtar, Tabish Chawla, Aneela Darbar, Wardah Rafaqat, Syed Shahabuddin, Noman Shahzad, Shahid Ahmed Sami

Section of Urology

Technological progress has changed the landscape of surgical practice. Minimally invasive surgery (MIS) and percutaneous interventions (PC) are constantly replacing open procedures. This reduces hospital stay and allows quicker recovery. The application of MIS should follow the good medical practice dictum by Hippocrates i.e. "First do no harm". To remain abreast with new procedures, the medical personnel are required to update and enhance their knowledge and skill. To ensure safety, the innovations are rigorously tested and tried. The learning curve of MIS is shortened by simulator training and proctorship. Credentialing processes are in place to enhance safe delivery of care. …

Four (44.4%) patients had infra-renal while …

Prognostic Value Of 6-Minute Walk Distance In Patients Undergoing Percutaneous Coronary Intervention: A Veterans Affairs Prospective Study, Tarun W Dasari, Bhavin Patel, Siddharth A Wayangankar, David Alexander, Yan D Zhao, Joann Schlegel, Cheuk Leung, Pedro Lozano, Faisal Latif, Udho Thadani

The Texas Heart Institute Journal

The 6-minute walk distance (6MWD) test is a useful prognostic tool in chronic heart failure. Its usefulness after percutaneous coronary intervention is unknown.

In a prospective observational study, patients underwent a 6MWD test within 2 weeks after percutaneous coronary intervention. The primary endpoint was major adverse cardiovascular events (MACE) (death, acute coronary syndrome, and heart failure admission) at one year. Receiver operating characteristic curves and area under the curve were used to determine the 6MWD test's predictive power, and the Youden index was used to measure its effectiveness.

A total of 212 patients were enrolled (98% men; mean age, 65 …

Unusual Cause Of Heart Failure In A Patient With Marfan Syndrome: A Late Complication Of Bioprosthetic Valved Graft Replacement, Prerna B Bansal, Hari P Chaliki, Kantha R Kolla, Roger L Click, Alberto Pochettino

The Texas Heart Institute Journal

A high-velocity gradient across the left ventricular outflow tract is most often caused by aortic valve stenosis. We describe the unusual case of a high-velocity gradient caused by a kinked ascending aortic graft in a 69-year-old man who had Marfan syndrome. The patient had a history of ascending aortic aneurysm and had previously undergone replacement of the aortic root and ascending aorta with use of a bioprosthetic valved graft. The kinking was caused by dilation of the native aortic arch. The patient underwent successful hemi-arch replacement and repair of the kinked graft. Late complications and reoperation after proximal aortic surgery …

Benefit Of Contact Force-Guided Catheter Ablation For Treating Premature Ventricular Contractions, Ziming Zhao, Xiaowei Liu, Lianjun Gao, Yutao Xi, Qi Chen, Dong Chang, Xianjie Xiao, Jie Cheng, Yanzong Yang, Yunlong Xia, Xiaomeng Yin

The Texas Heart Institute Journal

We evaluated whether an irrigated contact force–sensing catheter would improve the safety and effectiveness of radiofrequency ablation of premature ventricular contractions originating from the right ventricular outflow tract.

We retrospectively reviewed the charts of patients with symptomatic premature ventricular contractions who underwent ablation with a contact force–sensing catheter (56 patients, SmartTouch) or conventional catheter (59 patients, ThermoCool) at our hospital from August 2013 through December 2015. During a mean follow-up of 16 ± 5 months, 3 patients in the conventional group had recurrences, compared with none in the contact force group. Complications occurred only in the conventional group (one steam …

Obstruction Of 2 Coronary Arteries From Different Causes Immediately After Transapical Transcatheter Aortic Valve Replacement, Umihiko Kaneko, Ryuji Koshima, Hirosato Doi, Tsutomu Fujita

The Texas Heart Institute Journal

Coronary obstruction, a rare complication of transcatheter aortic valve replacement, can be fatal. Few data exist on this phenomenon, and, to date, authors have reported only single coronary lesions. We present a case in which 2 coronary arteries obstructed immediately after transapical transcatheter aortic valve replacement. The patient was an 81-year-old woman with symptomatic severe aortic stenosis who underwent transapical transcatheter aortic valve replacement. Immediately after an Edwards Sapien XT valve was deployed, she experienced sudden cardiogenic shock resulting from obstruction of the left main coronary artery ostium and the distal left anterior descending coronary artery. The left main obstruction …

A Crescent Lesion Set Avoiding Esophageal Contact Is Not Inferior To Standard Waca For Paroxysmal Afib: A Pilot Study, Jeraim Craig, David Goldgrab Do, Sokol Kalaveshi, Ruifang Yang Md, Jose Luis Henao, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: Radiofrequency ablation using wide area circumferential ablation (WACA) is the standard approach for paroxysmal atrial fibrillation (pAF). Invariably the posterior wall requires RFA to isolate the pulmonary veins (PV). However, excessive heating of the posterior wall can lead to catastrophic esophageal injury. It has been reported that pulmonary vein isolation can be achieved without fully encircling the PV antra. When WACA is not feasible then a semilunar/crescent lesion set (CL) limiting posterior wall ablation can be considered.

Methods:A non‐randomized prospective study comparing highly symptomatic patients with pAF who underwent WACA with a study group who had a …

Is The Thomas Ring An Effective Approach To Prevent Recurrence Of Persistent Atrial Fibrillation With Advanced Atrial Fibrosis?, Ruifang Yang Md, Jose Luis Henao Md, David Goldgrab Do, Sokol Kalaveshi Md, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: Pulmonary vein isolation (PVI) with the Thomas ring (TR, single ring posterior wall isolation) has been shown to reduce recurrence of primarily paroxysmal atrial fibrillation (AF). Atrial fibrosis, as an important pathophysiological contributor, is directly linked to AF recurrence and resistance to therapy. The effect of TR ablation on outcomes of persistent AF (peAF) with advanced atrial fibrosis has not been adequately studied.

Methods: Observational series of three peAF patients (Tab.) who underwent TR. The degree of atrial fibrosis was determined by electroanatomic bipolar voltage mapping (CARTO, Diamond Bar, CA, USA). The reduced voltage areas (Fig.) reflected …

Ablation Of Persistent Atrial Fibrillation Substrate In Sinus Rhythm Does Not Lead To An Underestimation Of Fibrotic Atrial Myopathy: A Pilot Study, David Goldgrab Do, Sokol Kalaveshi Md, Jose Luis Henao Md, Ruifang Yang Md, Jearim Craig, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: Ablation of persistent atrial fibrillation (peAF) is associated with a worse outcome. Fibrotic atrial myopathy (FAM) is thought to play a role in the progression of AF. Estimation of left atrial voltage can vary significantly based on whether mapping is performed in fibrillatory conduction or sinus rhythm (SR). Selection of a voltage scale (VS) may lead to an over/under estimation of FAM. We determined the prevalence of advanced atrial myopathy (FAM > = 2) in SR compared to historical cohort ablated in peAF.

Methods: A homogenous group of peAF patients who underwent ablation in SR following cardioversion were …

Cardioversion Of Persistent Atrial Fibrillation Before High Energy Ablation Does Not Improve Outcomes In Short Term Follow Up: Preliminary Analysis, Ruifang Yang Md, Sokol Kalaveshi Md, David Goldgrab Do, Jose Luis Henao Md, Stephen Mester Md, Christian Perzanowski Md

Cardiology

Introduction | Objectives: The optimal approach of ablating persistent Atrial Fibrillation (peAF) has yet to be defined. By convention, mapping/ablation of peAF is most often performed in AF. The success of ablation hinges on catheter contact and achieving lesion transmurality. We theorized that ablation efficacy would improve during sinus rhythm (SR) given stability and predictability of catheter contact.

Methods: Non‐randomized comparison of peAF patients who underwent ablation in SR under a new practice protocol versus a cohort of peAF ablated in AF. The lesion set was the same for both groups, WACA ± BOX. Study group was treated with higher …

A Case Of Blunt Trauma-Induced St-Elevation Myocardial Infarction Sustained During A Prison Brawl., Zachary T Clark, Natalie Thiel, John Perry, Michael R Minckler

Articles, Abstracts, and Reports

Myocardial infarction (MI) is a serious and time-sensitive condition. MIs are typically seen in patients with coronary artery disease (CAD) and are caused by the rupture of an atherosclerotic plaque due to factors contributing to plaque instability. However, this case illustrates that plaque rupture can also be caused by blunt trauma to the chest. Considering MI as a possible result of chest trauma may decrease time from presentation to diagnosis and treatment and, therefore, improve outcomes in similar cases, particularly when patients presents unusually or with very few risk factors for MI.

Implications Of C1q/Tnf-Related Protein Superfamily In Patients With Coronary Artery Disease., Yanwei Zhang, Caihong Liu, Jing Liu, Rui Guo, Zheyi Yan, Wenxia Liu, Wayne Bond Lau, Xiangying Jiao, Jimin Cao, Kun Xu, Yongping Jia, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

The C1q complement/TNF-related protein superfamily (CTRPs) displays differential effects on the regulation of metabolic homeostasis, governing cardiovascular function. However, whether and how they may serve as predictor/pro-diagnosis factors for assessing the risks of coronary artery disease (CAD) remains controversial. Therefore, we performed a clinical study to elaborate on the implication of CTRPs (CTRP1, CTRP5, CTRP7, and CTRP15) in CAD. CTRP1 were significantly increased, whereas CTRP7 and CTRP15 levels were decreased in CAD patients compared to the non-CAD group. Significant differences in CTRP1 levels were discovered between the single- and triple-vascular-vessel lesion groups. ROC analysis revealed that CTRP7 and CTRP15 may …

Spotlight On Icosapent Ethyl For Cardiovascular Risk Reduction: Evidence To Date, Xiaoming Jia, Stephanie Koh, Mahmoud Al Rifai, Roger S. Blumenthal, Salim S. Virani

Office of the Provost

Icosapent ethyl is a highly purified formulation of eicosapentaenoic acid, a type of omega-3 fatty acid contained in fish oil. While omega-3 fatty acids have long been thought to have cardioprotective benefits, the Reduction of Cardiovascular Events with EPA-Intervention Trial (REDUCE-IT) has helped to establish icosapent ethyl as an evidence-based therapy for risk reduction of atherosclerotic cardiovascular disease (ASCVD). REDUCE-IT, however, was by no means an overnight success story. Close examination of the evidence shows that the trial was a culmination of many lessons learned from previous studies. The purpose of this manuscript is to review contemporary evidence of icosapent …

Sevoflurane Pre-Conditioning Ameliorates Diabetic Myocardial Ischemia/Reperfusion Injury Via Differential Regulation Of P38 And Erk., Dina Xie, Jianli Zhao, Rui Guo, Liyuan Jiao, Yanqing Zhang, Wayne Bond Lau, Bernard Lopez, Theodore Christopher, Erhe Gao, Jimin Cao, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

Diabetes mellitus (DM) significantly increases myocardial ischemia/reperfusion (MI/R) injury. During DM, cardioprotection induced by conventional pre-conditioning (PreCon) is decreased due to impaired AMP-activated protein kinase (AMPK) signaling. The current study investigated whether PreCon with inhaled anesthetic sevoflurane (SF-PreCon) remains cardioprotective during DM, and identified the involved mechanisms. Normal diet (ND) and high-fat diet (HFD)-induced DM mice were randomized into control and SF-PreCon (3 cycles of 15-minute period exposures to 2% sevoflurane) groups before MI/R. SF-PreCon markedly reduced MI/R injury in DM mice, as evidenced by improved cardiac function (increased LVEF and ±Dp/dt), decreased infarct size, and decreased apoptosis. To determine …

Prevalence Of Sensorineural Hearing Loss In Children With Palliated Or Repaired Congenital Heart Disease., Lalitha Gopineti, Mane Paulpillai, Andrea Rosenquist, Andrew H. Van Bergen

Manuscripts, Articles, Book Chapters and Other Papers

Background Children with congenital heart disease (CHD) are at increased risk of neurodevelopmental deficits, and the presence of sensorineural hearing loss (SNHL) may further lead to poor language skills acquisition and speech delays. Prevalence of SNHL in the general pediatric population is estimated to be 0.2% at birth to 0.35% during adolescence. Very few studies have attempted to estimate SNHL prevalence in children who have undergone congenital heart surgery. Methods This retrospective study aimed to estimate SNHL prevalence in children who underwent congenital heart surgery in our institution and were followed up in our high-risk pediatric cardiology clinics for four …

Usefulness Of Elevated Troponin To Predict Death In Patients With Covid-19 And Myocardial Injury., D. T. Majure, L. Gruberg, S. G. Saba, C. Kvasnovsky, J. S. Hirsch, R. Jauhar, Northwell Health Covid-19 Research Consortium

Journal Articles

Elevations in troponin levels have been shown to predict mortality in patients with coronavirus disease 2019 (COVID-19). The role of inflammation in myocardial injury remains unclear. We sought to determine the association of elevated troponin with mortality in a large, ethnically diverse population of patients hospitalized with COVID-19, and to determine the association of elevated inflammatory markers with increased troponin levels. We reviewed all patients admitted at our health system with COVID-19 from March 1 to April 27, 2020, who had a troponin assessment within 48 hours of admission. We used logistic regression to calculate odds ratios (ORs) for mortality …
