Objective Although the combination of doxorubicin (Dox) and trastuzumab (Trz) reduces breast cancer progression and recurrence, it is limited by significant cardiotoxic side effects. Little is known about the utility…
Marti L. McCulloch, BS, MBA, RDCS, FASE It is with mixed emotions to note that this is my last column for the Yellow Pages. As the Sonographer Council chair, I…
Background Noninvasive calculation of pulmonary vascular resistance (PVR) has been reported to be feasible. We therefore evaluated whether baseline PVR could predict clinical outcomes in patients with acute pulmonary thromboembolism…
Background Transthoracic echocardiographic estimates of peak systolic pulmonary artery pressure are conventionally calculated from the maximal velocity of the tricuspid regurgitation (TR) jet. Unfortunately, there is insufficient TR to determine…
Background The aims of this study were to evaluate the three-dimensional features and geometric determinants of the vena contracta (VC) in functional tricuspid regurgitation (TR) and to identify optimal width…
Background Left atrial (LA) enlargement has been acknowledged as a significant predictor of cardiovascular morbidity and mortality. Methods To evaluate the accuracy of two-dimensional and three-dimensional echocardiography for determining LA…
Background Substantial variability in sequential echocardiographic right ventricular (RV) quantification may exist. Interobserver and intraobserver values are well known, but acquisition (test-retest) variability has been rarely assessed. The objective of…
Background The authors hypothesized that in patients with heart failure with normal left ventricular (LV) ejection fraction (HFNEF), the same fibrotic processes that affect the subendocardial layer of the left…
Background Cardiac fibrosis is an important complication of intestinal carcinoid disease, with resulting valvular and ventricular dysfunction due to endocardial fibrosis. Evaluation of right ventricular (RV) function in these patients…
Background Catheter-based mitral valve clip repair (CBMCR) is feasible for selected patients with mitral regurgitation (MR). Two-dimensional (2D) transesophageal echocardiography (TEE) is the standard modality for evaluating MR and procedural…
