Coronary Revascularization Versus Optimal Medical Therapy In Renal Transplant Candidates With Coronary Artery Disease: A Systematic Review And Meta-Analysis., Muhammad U Siddiqui, Joey Junarta, Gregary D. Marhefka

Department of Medicine Faculty Papers

Background Coronary artery disease (CAD) is highly prevalent in patients with chronic kidney disease and is a common cause of mortality in end-stage renal disease. Thus, patients with end-stage renal disease are routinely screened for CAD before renal transplantation. The usefulness of revascularization before transplantation remains unclear. We hypothesize that there is no difference in all-cause and cardiovascular mortality in waitlisted renal transplant candidates with CAD who underwent revascularization versus those treated with optimal medical therapy before transplantation. Methods and Results This meta-analysis was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. MEDLINE, Scopus, and …

Three-dimensional and 2D LV GLS, as well as regional strain in 16 myocardial segments were quantified. Bland Altman analysis, intra- class correlation coefficients (ICC), percent error and linear regression were used …

Surgical Management Of Atrial-Esophageal Fistula As A Complication Of Atrial Fibrillation Ablation., Amber Duda, Kevin Beers, Mohi Mitiek

Manuscripts, Articles, Book Chapters and Other Papers

Atrial-esophageal fistula (AEF) is a rare, but life-threatening complication of ablative treatments for atrial fibrillation. Although the incidence of this complication is low, the mortality is very high. There are many surgical approaches to this disease but we offer a novel technique to reduce the number of incisions used and provides central cannulation. It also allows for repair of both the esophagus and atrium and buttresses these repairs, which have both been shown to decrease morbidity and mortality. The technique has been successful in our three patients and can be considered as an approach to surgical management of AEF.

RATIONALE: Dextro-transposition of the great arteries (D-TGA) is a severe congenital heart defect which affects approximately 1 in 4,000 live births. While there are several reports of D-TGA patients with rare variants in individual genes, the majority of D-TGA cases remain genetically elusive. Familial recurrence patterns and the observation that most cases with D-TGA are sporadic suggest a polygenic inheritance for the disorder, yet this remains unexplored.

OBJECTIVE: We sought to study the role of common single nucleotide polymorphisms (SNPs) in risk for D-TGA.

METHODS AND RESULTS: We conducted a genome-wide association study in an international set of 1,237 patients …

A Vanishing Cardiac Mass, Moayad M. Alqurashi, Ahmed Alsaileek, Thamer H. Alenazi, Basel M. Alhaijani, Ahmed Aljizeeri

Journal of the Saudi Heart Association

The prevalence of extrapulmonary tuberculosis (TB) is very common in the Middle East; however, myocardial involvement is among the most infrequent manifestations of extrapulmonary TB. We present an asymptomatic young adult who was incidentally found to have a large right atrial tuberculoma, diagnosed by non-invasive cardiac imaging and effectively treated with standard first-line anti-TB treatment, steroids, and anticoagulation. This case is a classical presentation of nodular myocardial involvement of TB, highlighting advantages of advanced imaging, e.g., cardiac magnetic resonance (CMR) and multidisciplinary treatment.

Speckle Tracking Echocardiographic Assessment Of Left Ventricular Function By Myocardial Strain Before And After Aortic Valve Replacement, Gajinder Pal Singh Kaler, Rakesh Mahla, Himanshu Mahla, Sarita Choudhary, Gurdarshan Singh, Raghuveer Prasad Patel, Navjot Kaur Kaler

Journal of the Saudi Heart Association

Background & Objectives: In patients of aortic stenosis and regurgitation, pressure and volume effects on left ventricular function are occult and missed by routine echocardiography markers like ejection fraction (EF). Speckle tracking analysis by measuring global longitudinal strain and global circumferential strain seems to ascertain this occult LV function parameters at an early phase in a more comprehensive manner. Limited studies have examined these parameters pre/post aortic valve replacement (AVR). Methods: 94 consecutive patients with symptomatic severe aortic stenosis (AS) or aortic regurgitation (AR), planned for AVR were included (as per set inclusion criteria) along with 15 normal controls-15 months …

Stroke Prevention In Patients With Non-Valvular Atrial Fibrillation: The Watchman Device Versus Warfarin, Emma Delaney

Theses and Graduate Projects

Atrial fibrillation is a common heart arrhythmia that leads to an increased risk of stroke. Warfarin was the original anticoagulant that would be used as the treatment for atrial fibrillation. However, there are people who have contraindications to anticoagulation or are a high fall risk and shouldn’t be on Warfarin. The Watchman Device was originally designed in 2005 as a way to close the left atrial appendage where clots are usually present with atrial fibrillation. The watchman may be a superior way to help reduce the risk of stroke compared to the traditional use of Warfarin. Purpose: Literature review …
