Right ventricular reserve in cardiopulmonary disease: a simultaneous hemodynamic and three-dimensional echocardiographic study.

Background: RV reserve has been linked to exercise capacity and prognosis in cardiopulmonary diseases. However, evidence in this setting is limited, due to the complex shape and load dependency of the RV. We sought to study right ventricular (RV) adaptation to exercise by simultaneous three-dimensional echocardiography (3DE) and right heart catheterization (RHC).

UTILITY OF THE RATIO BETWEEN THE SIZE OF THE RIGHT ATRIUM AND THE RIGHT VENTRICLE AT END-SYSTOLE TO DIAGNOSE ATRIAL SECONDARY TRICUSPID REGURGITATION.

Background: In the multiparametric framework for diagnosing atrial secondary tricuspid regurgitation (A-STR), an end-systolic (ES) right atrial (RA) to right ventricular (RV) volume or area ratio ≥1.5 supports the diagnosis of A-STR over the ventricular STR phenotype (V-STR). However, this threshold value has never been tested.

Mitral valve repair with the semi-rigid Memo 4D annuloplasty ring: early clinical and echocardiographic outcomes from the MANTRA study.

Objectives: Memo 4D is a semi-rigid ring with an exclusive saddle shape and progressive increased anteroposterior diameter. This preliminary analysis reports 30-day clinical and haemodynamic outcomes of the MANTRA Memo 4D sub-study.

Methods: MANTRA is an 'umbrella' prospective, multicentre, worldwide post-market study to collect real-life safety and performance data on the Corcym devices.

Discrepancy in the Diagnosis of Heart Failure With Preserved Ejection Fraction Between Supine Versus Upright Exercise Hemodynamic Testing.

Background: Invasive exercise right heart catheterization is a gold standard in diagnosing heart failure with preserved ejection fraction (HFpEF). Body positions during the test influence hemodynamics. However, the discrepancy in HFpEF diagnosis between exercise testing in supine versus upright position is unknown.
