Impact of right ventricular dysfunction and end-diastolic pulmonary artery pressure estimated from analysis of tricuspid regurgitant velocity spectrum in patients with preserved ejection fraction.

Aims: We aimed to analyse the association between right haemodynamic parameters, right ventricular (RV) dysfunction parameters, and outcomes in patients with preserved ejection fraction (EF).

Methods And Results: Retrospective analysis of right haemodynamic (systolic pulmonary pressure and end-diastolic pulmonary pressure based on tricuspid regurgitation (TR) velocity at pulmonary valve opening time), and RV parameters including size (end-diastolic and end-systolic area), function (RV fractional area change, Tei index, Tricuspid Annular Plane Systolic Excursion, and speckle tracking derived free wall strain), from 557 consecutive patients with preserved EF [EF ≥ 50%; age 64.9 + 20; 52% female; co-morbidity Charlson index 4.

Clinical Outcome of Isolated Tricuspid Regurgitation in Patients with Preserved Left Ventricular Ejection Fraction and Pulmonary Hypertension.

Background: The outcome of tricuspid regurgitation (TR) remains unclear because of heterogeneity of etiology and the contradictory results of outcome studies. The aim of this study was to evaluate the clinical outcomes of TR in patients with pulmonary hypertension (PH) and normal left systolic function, stratified to patients with post- or precapillary PH.

Methods: In patients with no left valvar disease (isolated) functional TR, preserved left systolic function (ejection fraction ≥ 50%), and PH (systolic pulmonary pressure > 50 mm Hg), TR was assessed both qualitatively (grade) and semiquantitatively using the vena contracta method, and retrospective analysis of long-term outcomes was conducted.

Impact of Right Ventricular Dysfunction and Tricuspid Regurgitation on Outcomes in Patients Undergoing Transcatheter Aortic Valve Replacement.

Background: Right ventricular (RV) dysfunction and tricuspid regurgitation (TR) may coexist with aortic stenosis. The aim of this study was to assess the association between RV dysfunction, TR, associated comorbidities, and outcomes following transcatheter aortic valve replacement (TAVR).

Methods: A retrospective analysis was conducted of baseline and 6-month clinical and echocardiographic parameters, including TR grade, RV size (grade, end-diastolic and end-systolic areas, annular diameter), and function (grade, tricuspid annular plane systolic excursion [TAPSE], fractional area change, Tei index), in 519 consecutive TAVR patients.
