Diagnosis Using CCTA and Management of Anomalous Right Coronary Artery from the Opposite Sinus
Coronary anomalies can be observed in 1–1.2% of all angiograms performed. Majority of coronary anomalies are benign and do not lead to cardiac ischemia; however anomalous coronary arteries from the opposite sinus (ACAOS) are often associated with sudden cardiac deaths, typically in 0.11–0.35% of individuals who participate in vigorous physical activity (Peñalver et al., 2012). Left and right ACAOS have an incidence of 0.15% and 0.92%, respectively. Left ACAOS are often associated with higher incidence of sudden cardiac death; this could be secondary to greater territory of myocardial perfusion by the left coronary artery. ACAOS are often asymptomatic and initially present as sudden death following exertion in young athletes. The management of left ACAOS is clear and surgery is usually indicated. However there is a lack of consensus on the management of certain cases of right ACAOS. In this paper a case of 20 yo M with right coronary artery from left sinus is going to be presented with a discussion on pathophysiology, diagnosis, and management

Relationship between MRI-based mechanical activation delays and direct intraoperative measurements of electrical delay in patients undergoing cardiac resynchronization
Mitral regurgitation after anthracycline exposure: a case report
We report the case of a 66-year-old African American female with a history of breast cancer previously treated with anthracycline based chemotherapy presenting with significant mitral regurgitation. She initially had preserved left ventricular systolic function with normal cardiac chamber dimensions, however, she developed progressive left ventricular chamber dilation and mild reduction in systolic function, which prompted surgical correction of her mitral regurgitation. After surgical mitral valve repair, she developed overt left ventricular failure with severe systolic dysfunction; however, she responded well to subsequent medical therapy
A COMPARISON OF THE PROGNOSTIC VALUE OF POST-TRANSCATHETER AORTIC VALVE REPLACEMENT PARAVALVULAR LEAK GRADING BY ECHOCARDIOGRAPHIC VARC-2 CRITERIA VERSUS CARDIOVASCULAR MAGNETIC RESONANCE
Case Report Internal Jugular Venous Pseudoaneurysm in a Patient with Heart Failure and Severe Tricuspid Regurgitation
The differential diagnosis of a lateral neck mass includes a number of possible etiologies. While jugular venous aneurysms and pseudoaneurysms are rare entities, they should be considered in the differential diagnosis of a pulsatile lateral neck mass. We present a case of an idiopathic jugular venous pseudoaneurysm and its association with worsening tricuspid regurgitation in a patient with heart failure with preserved ejection fraction
