Department of Cardiovascular Medicine, Wakayama Medical University, Wakayama, Japan.
Background: Assessment of right ventricular (RV) function remains challenging because of its complex geometry. Application of speckle-tracking echocardiography (STE) to the tricuspid annulus provides rapid and automated assessment of the midpoint of the tricuspid annular plane displacement (TAD). The aim of this study was to investigate the value of tissue-tracking TAD for the assessment of RV systolic dysfunction. Read More

Aims: Bivalvular functional regurgitation (BVFR) defined as concomitant mitral and tricuspid insufficiency has not been described or systematically assessed before. Therefore, this study sought to define incidence, impact and natural history of BVFR in heart failure with reduced ejection fraction (HFrEF) to provide the foundation for risk assessment and directions for potential treatment strategies.
Methods And Results: We enrolled 1021 consecutive patients with HFrEF under guideline-directed medical therapy and performed comprehensive echocardiographic and neurohumoral profiling. Read More

Intracardiac hemodynamic forces have been proposed to influence remodeling and be a marker of ventricular dysfunction. We aimed to quantify the hemodynamic forces in patients with repaired tetralogy of Fallot (rToF) to further understand the pathophysiological mechanisms as this could be a potential marker for pulmonary valve replacement (PVR) in these patients. Patients with rToF and pulmonary regurgitation (PR) > 20% ( n = 18) and healthy control subjects ( n = 15) underwent MRI, including four-dimensional flow. Read More

Background: Far less attention has been paid to the prognostic effect of right-side heart disease on outcomes after transcatheter aortic valve replacement (TAVR) when compared with the left side. Therefore, we performed a systematic review and meta-analysis on the impact of tricuspid regurgitation (TR) and right ventricular (RV) dysfunction on outcomes after TAVR.
Hypothesis: We hypothesized that TR and RV dysfunction may have a deleterious effect on outcomes after TAVR. Read More

The facilitation of proper blood flow through the heart depends on proper function of heart valve components, and alterations to any component can lead to heart disease or failure. Comprehension of these valvular diseases is reliant on thorough characterization of healthy heart valve structures for use in computational models. Previously, computational models have treated these leaflet structures as a structurally and mechanically homogenous material, which may not be an accurate description of leaflet mechanical response.

A 59-year-old man who had undergone catheter ablations for paroxysmal atrial fibrillation (AF) twice was referred for a third procedure due to atrial tachycardia (AT) recurrence. In addition to pulmonary vein (PV) isolation, linear ablation (roof/mitral isthmus lines), cavo-tricuspid isthmus ablation and superior vena cava (SVC) isolation had been conducted in the previous procedures. The intracardiac electrograms showed AT with irregular cycle length, and a circular mapping catheter obliquely placed in the SVC showed both fibrillatory activation and organized activation simultaneously.

Background: Tricuspid annular plane systolic excursion (TAPSE) is an established index of right ventricular (RV) systolic function and a significant predictor in normotensive patients with pulmonary embolism (PE). Recently, Doppler tissue imaging-derived tricuspid annular systolic velocity (TV S'), a modern parameter of RV function was reported to be useful in the diagnosis and prognosis of a broad spectrum of heart diseases. Therefore, herein, is an analysis of the prognostic value of both parameters in normotensive PE patients. Read More

Until recently, tricuspid valve (TV) disease has been relatively neglected for a long time, but recently tricuspid regurgitation (TR) has attracted attention. Although the prognosis of patients with these disorders is poor, the high mortality and morbidity associated with TV surgery have resulted in many patients not receiving surgical therapy. Current guidelines recommend that TV surgery should be considered in patients with severe TR who are symptomatic or have progressive right ventricle (RV) dilatation or dysfunction. Read More

Findings from early percutaneous tricuspid intervention trials have shown that the severity of tricuspid regurgitation (TR) far exceeded the current definition of severe TR. Also, the improvement in the amount of TR following tricuspid intervention is not accounted for by the current definition of TR as different degrees of severity at the severe end was grouped under the same umbrella term of "severe." There has been a recent call to expand the TR grading system, encompassing two more grades, namely "massive" and "torrential" TR, in the order of increasing severity. Read More

Background: Patients with heart failure (HF) often show signs of RV dysfunction. The function of RV coupled with the pulmonary circulation (tricuspid annular plane systolic excursion [TAPSE]: pulmonary artery systolic pressure [PASP]) has been shown to divide HF patients into distinct prognostic strata, however less is known about which factors influence this prognostic marker, and whether these factors can be modified. We sought to obtain normative values and discern the individual effects of age, gender, and fluid overload on right ventricular (RV) function. Read More

Background: Pericardial tamponade is neither a clinical nor an echocardiographic diagnosis alone. The echocardiogram carries diagnostic value and should be performed when there is suspicion for tamponade based on the history and physical exam. A pericardial effusion uncovered on point-of-care ultrasound (POCUS) may be mistaken for tamponade and thereby lead to inappropriate and invasive management with pericardiocentesis. Read More

The tricuspid annular plane systolic excursion (TAPSE) has evolved into one of the major echocardiographic indicators of systolic right ventricular (RV) longitudinal function in pediatric pulmonary hypertension (PH). Current RV function research in children with PH focusses on multi-parametric approaches that include TAPSE. The RV ejection efficiency (RVEe) is one of the new variables that reflects the relationship of TAPSE divided by the indexed pulmonary vascular resistance (PVRi) measured by cardiac catheterization.
