Background Peak systolic mitral annular velocity (S m ) measured by tissue Doppler echocardiography has been recognized as an independent predictor of mortality in patients with heart failure and in…
Background Stroke distance of the left ventricular outflow tract (LVOT) or pulmonary artery (PA) is readily measurable by Doppler echocardiography. Stroke distance, calculated by the velocity time integral, expresses the…
A 28-year-old Cambodian man with a history of congenital heart disease presented with a 6-month history of increasing fatigue, night sweats, and weight loss. His surgical history included two Blalock-Taussig…
Background The diagnosis of noncompaction cardiomyopathy (NCCM) remains subject to controversy. Because NCCM is probably caused by an intrauterine arrest of the myocardial fiber compaction during embryogenesis, it may be…
Background The aim of this study was to evaluate the relation of basal and hyperemic coronary flow with myocardial functional improvement in patients with previous myocardial infarction undergoing elective percutaneous…
Background Long-term right ventricular apical pacing (RVAP) can lead to adverse clinical outcomes. Although left ventricular (LV) dyssynchrony is the major causative factor, other potential mechanisms are not fully understood….
Background Aging and gender may affect left ventricular (LV) mechanics. The aim of this study was to determine the age and gender dependency of LV mechanical indices obtained from real-time…
Background Although transesophageal echocardiography is the definitive test for the detection of left atrial (LA) appendage thrombus, transthoracic echocardiography has yet to prove useful for the determination of increased risk…
Background The aim of this cross-sectional study was to explore the association between echocardiographic parameters and CHADS 2 score in patients with nonvalvular atrial fibrillation (AF). Methods Seventy-seven subjects (36…
Background Although there is anatomopathologic evidence of atrial involvement in Chagas cardiomyopathy (CCM), the impact in left atrial (LA) function is unknown. The aim of this study was to evaluate…
