The echocardiographic index TAPSE/PASP serves as a non-invasive surrogate for right ventricular-pulmonary arterial coupling and has extensive clinical utility in evaluating patients with heart failure.
Does the echocardiographic index TAPSE/PASP accurately reflect right ventricular-pulmonary arterial coupling in patients with heart failure?
TAPSE/PASP is a validated, non-invasive echocardiographic surrogate for assessing right ventricular-pulmonary arterial coupling in heart failure.
Heart failure (HF), with its high morbidity and mortality, remains a global public health issue. Right ventricular (RV) dysfunction is a sign of deterioration in the natural history of HF, and a thorough evaluation of the relationship between RV contractility and its afterload through RV-pulmonary arterial (RV-PA) coupling can aid in accurately assessing overall RV function. The ratio of RV end-systolic elastance (Ees) to pulmonary arterial elastance (Ea) invasively measured by right heart catheterization served as the gold standard for evaluating RV-PA coupling. An echocardiographic index termed tricuspid annular plane systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP) has been shown to correlate well with Ees/Ea. TAPSE/PASP is recognized as a non-invasive surrogate of RV-PA coupling and has been extensively studied in patients with HF. This review briefly describes the methods of assessing RV-PA coupling, mainly discussing echocardiography, summarizes the clinical utility of TAPSE/PASP in patients with different HF types, and provides an overview of the available literature.
Chen et al. (Tue,) conducted a review in Heart failure. TAPSE/PASP (tricuspid annular plane systolic excursion/pulmonary artery systolic pressure) was evaluated. The echocardiographic index TAPSE/PASP serves as a non-invasive surrogate for right ventricular-pulmonary arterial coupling and has extensive clinical utility in evaluating patients with heart failure.
