Background Intraoperative real-time three-dimensional transesophageal echocardiography has been shown useful in the evaluation of the mitral valve (MV) apparatus, and dedicated commercial software allows its quantitative assessment. The aims of…
Background Doppler-derived hemodynamic data for normal tricuspid mechanical valve prostheses are limited. Methods A comprehensive retrospective Doppler echocardiographic assessment of 78 normal St. Jude Medical Standard (St. Jude Medical, Inc.,…
Background Assessment of the functional significance of left anterior descending coronary artery (LAD) stenosis of intermediate severity (50%–70% diameter stenosis) is challenging. The aim of this study was to compare…
Background The aims of this study were to detect subclinical left ventricular (LV) dysfunction and to determine the impact of arterial hypertension on LV systolic function using speckle-tracking echocardiography in…
Background In asymptomatic mitral stenosis (MS), the usefulness of peak exercise Doppler echocardiography (DE) values is acknowledged, but the role of values recorded during the first stage of DE remains…
Background Because of the shortage of donor hearts, the criteria for acceptance have been considerably expanded. Abnormal results on pharmacologic stress echocardiography are associated with significant coronary artery disease and/or…
CFR in Clinical Practice Myocardial ischemia is the metabolic derangement that results when myocardial blood flow is insufficient to meet demand. Epicardial coronary artery disease that is moderate to severe,…
Background The aim of this study was to investigate the incidence and predictors of neuropsychiatric (NP) symptoms during 24 hours after dobutamine-atropine stress testing (DST). Methods Consecutive outpatients undergoing DST…
