While a TAPSE as low as 16 mm has been shown to cor-relate with RV systolic dysfunction in a patient population with coronary artery disease (12, 18), patients in this pres-ent study were divided into two groups: TAPSE <18 mm and ≥18 mm. In the discharge group, low TAPSE was defined as TAPSE … The TAPSE measurement method is simple and has low dependence on the ultrasound image quality, requires no specific ultrasound equipment and analysis software, and has high repeatability. ** HELPFUL TIP: It is VITAL that we make sure we obtain both TAPSE and S’ Wave values to correlate together. Within each cohort, patients were separated according to the TAPSE tertiles: in the admission group: low, TAPSE <16 mm; intermediate, TAPSE between 16 and 20 mm; and high, TAPSE >20 mm. Representation of the results (mean ± SD) obtained in right ventricular ejection fraction (RVEF), tricuspid annular plane systolic excursion (TAPSE), peak systolic velocity of tricuspid annulus (PSV), and systolic pulmonary arterial pressure (SPAP) at the pre-operative evaluation (preop) and during the follow-up at 3, 6, and 12 months after surgery. The reference range provided is a cutoff range with a S’ value less than 9.5 cm/sec indicating RV dysfunction. The TAPSE cut-off of 18 mm was chosen based on contemporaneuos work from RV dysfunction in the setting of LV hyperdynamic function, in the example of acute PE, can cause a spuriously normal TAPSE. It should be pointed out, that the study by Floccari et al. Reduction of RV systolic function more closely predicts impaired exercise tolerance and poor survival than does left ventricular (LV) systolic function. This group was characterized by low values of TAPSE (around 16 mm) and high values of systolic blood pressure in the pulmonary artery (about 38 mmHg). Patients with higher TAPSE were less likely to have ischemic heart disease (P =.008) and had higher systolic blood pressure (P =.004). The analysis included 15 patients with RVSD (TAPSE <14 mm) and 85 patients without RVSD (TAPSE ≥14 mm). The mean age of the study population was 41.2 ± 18 years, the mean time on hemodialysis was 36.3 ± 35 months, and there were 56 males (56%). included patients in the early stages of CKD, which means not on dialysis. The tricuspid annulus is also anchored against the myocardial skeleton and so it's quite affected by LV function. TAPSE averaged (25th percentile, 75th percentile) 12 (10,14) and 20 (17,22) mm in participants with low (≤14 mm) vs. high (.14 mm) TAPSE, respectively. Contrarily, a severely reduced LV function with severely reduced MAPSE will cause the TAPSE to measure low. Causes of low TAPSE in HF‐PEF are not only PH but also atrial fibrillation, cardiac dyssynchrony, and end‐stage left ventricular diastolic dysfunction, suggesting a role for chronic pressure overload in contributing to right ventricular systolic dysfunction. In total, 290 patients with PAH were included in the analysis and were stratified into tertiles according to TAPSE/PASP ratio (low: <0.19 mm/mmHg; middle: 0.19–0.32 mm/mmHg; high: >0.32 mm/mmHg).The majority of the patients were diagnosed with idiopathic PAH and were in WHO functional class III, presenting with severe precapillary PH with substantially elevated PVR and mPAP. Introduction Right ventricular (RV) systolic dysfunction is now recognized widely as a strong and independent predictor of adverse outcomes in patients with heart failure (HF). Low TAPSE is not very common; however, it was measured in people with no heart disease due to diagnostic misclassification and excessive ends of the normal spectrum. dardized criteria (4). Just like TAPSE there are no values based upon mild, moderate or severe.
