Background: Left ventricular ejection fraction falls when the myocardium has already lost a significant portion of its functional capacity. There are conflicting data on whether diastolic dysfunction precedes systolic dysfunction after cardiotoxic chemotherapy. We aimed to study systolic and diastolic dysfunction after cardiotoxic chemotherapy and whether diastolic dysfunction can predict subsequent risk of systolic dysfunction.

Information on clinical characteristics, acute management and outcome of patients with sustained VT is limited in our part of world. The aim of this study was to analyze the demography, hemodynamics, ECG features, underlying disease, mode of termination and outcome of patients presenting with VT.

This is a case report on non-Hodgkin lymphoma where the patient presented for the first time with heart failure and severe left ventricular systolic dysfunction due to lymphoma infiltrating the heart muscle and had simultaneous bilateral involvement of kidneys. This type of presentation has never been described in world literature and is the first reported case.

This combination presents unusual diagnostic as well as management problems. Apart from a few case reports, there is little in the literature on the combined stenosis of both semilunar valves.

The C242T polymorphism at the p22PHOX gene affects binding of p22PHOX to heme, leading to variants of NADPH oxidase that produce different levels of reactive oxygen species (ROS). Specific variations in ROS are associated with an altered risk of developing cardiovascular disease.

We present a case of a young asymptomatic patient who developed acute atrial fibrillation with antegrade conduction over the atrioventricular bypass tract and very high ventricular rate after accidental low voltage electric injury, which was reverted successfully by DC shock.

We present dynamic multidetector computerized tomography and cine magnetic resonance imaging features of a case of subaortic aneurysm arising from interaortic-mitral valvular region in a child with past history of infective endocarditis.
