Clinical Impact of Size, Shape, and Orientation of the Tricuspid Annulus in Tricuspid Regurgitation as Assessed by Three-Dimensional Echocardiography.
Tricuspid annuloplasty for tricuspid regurgitation (TR) depends on the measurements of tricuspid annular diameter (TAD) obtained in an apical four-chamber view on two-dimensional (2D) transthoracic echocardiography (TTE). We performed a combined 2D and three-dimensional (3D) echocardiographic study to understand the impact of the size, shape, and orientation of a dilated annulus on the inconsistencies between measured 2D TTE-TAD and the actual annular diameter. ⋯ The inconsistencies between measured 2D TTE-TAD and the actual annular diameter can be explained through morphologic factors such as TA size and orientation.

Prognostic Value of Tricuspid Valve Geometry and Leaflet Coaptation Status in Patients Undergoing Tricuspid Annuloplasty: A Three-Dimensional Echocardiography Study.
The advent of three-dimensional echocardiography (3DE) enables detailed evaluation of the tricuspid valve (TV) apparatus; nonetheless, the clinical value of preoperative 3DE is unknown in patients undergoing tricuspid annuloplasty (TA). The aim of this study was to evaluate the prognostic value of TV geometric parameters and leaflet coaptation status evaluated by 3DE in patients undergoing TA. ⋯ Our study suggests that 3DE-derived TV tethering volume and ratio of total leaflet length to closure length are important preoperative measures associated with adverse events in patients undergoing TA.

ST-Segment Elevation Myocardial Infarction in Patients With Chronic Obstructive Pulmonary Disease: Prognostic Implications of Right Ventricular Systolic Dysfunction as Assessed with Two-Dimensional Speckle-Tracking Echocardiography.
Right ventricular (RV) systolic function in patients admitted with ST-segment elevation myocardial infarction (STEMI) with chronic obstructive pulmonary disease (COPD) and its impact on prognosis have not been characterized. The present study aims to compare the prevalence of RV systolic dysfunction in COPD versus non-COPD patients with STEMI and evaluate the prognostic implications. ⋯ In a STEMI population with relatively preserved LVEF, COPD patients had significantly worse RV FWSL compared with patients without COPD. Moreover, RV FWSL > -20% was independently associated with worse survival. In contrast, conventional parameters were not associated with survival.

Impact of High Baseline Left Ventricular Filling Pressure on Transcatheter Aortic Valve Replacement Outcomes in Patients with Significant Mitral Annular Calcification.
Left ventricular filling pressure (LVFP) has been demonstrated to be a major predictor of poor cardiovascular outcomes. However, estimation of LVFP in patients with aortic stenosis is limited by the high prevalence of significant mitral annular calcification. The aim of this study was to investigate the effect of transcatheter aortic valve replacement on LVFP and the relationship of LVFP to mortality and hospitalization. ⋯ High baseline LVFP was associated with a significantly increased all-cause mortality, and LVFP does not improve in the short term but only at 1 year after transcatheter aortic valve replacement.
