Validation of Prosthetic Mitral Regurgitation Quantification Using Novel Angiographic Platform by Mock Circulation

open access: hybridJACC: Cardiovascular Interventions, 2021
This study aimed to validate a dedicated software for quantitative videodensitometric angiographic assessment of mitral regurgitation (QMR).Quantitative videodensitometric aortography of aortic regurgitation using the time-density principle is a well-documented technique, but the angiographic assessment of mitral regurgitation (MR) remains at best semi-

Abolished ischemic tricuspid regurgitation by revascularization of left anterior descending artery: The role of collateral circulation [PDF]

open access: bronzeJournal of Cardiology Cases, 2014
A 74-year-old man presented with recent inferior wall myocardial infarction. The right ventricle (RV) was strikingly dilated and akinetic along the free wall compatible with right ventricular infarction. Accordingly, severe functional tricuspid regurgitation (TR) was detected.

Natural and Modified History of Atrioventricular Valve Regurgitation in Patients With Fontan Circulation

open access: bronzeJournal of the American College of Cardiology, 2022
Atrioventricular valve (AVV) regurgitation is increasingly prevalent in patients with a Fontan circulation.We sought to determine the impact of ventricular dominance and AVV operation on outcomes in patients with a Fontan circulation and ≥moderate AVV regurgitation.We conducted a retrospective study, including propensity score matching analysis, of 1 ...

Exercise-induced mitral regurgitation and right ventricle to pulmonary circulation uncoupling across the heart failure phenotypes [PDF]

open access: greenAmerican Journal of Physiology-Heart and Circulatory Physiology, 2020
Ex-MR is a common mechanism across the spectrum of HF subtypes and combines with ventilatory inefficiency and RV-PC uncoupling. Interestingly, in HFpEF, Ex-MR emerged as unexpectedly prevalent and peculiarly associated with increased chronotropic response and peripheral O2 extraction as potential adaptive mechanisms to backward flow redistribution.

Pressure reflection in the pulmonary circulation in patients with severe mitral regurgitation indicates adverse postoperative outcome [PDF]

open access: bronzeEuropean Journal of Cardio-Thoracic Surgery, 2013
Severe pulmonary hypertension (PH) is a known risk factor in valvular surgery. In the present study, we hypothesized that the assessment of pressure reflection (PR) in the pulmonary circulation, indicating increased pulmonary vascular resistance, might improve the identification of patients with increased morbidity and mortality following surgery for ...

Imaging and circulating biomarkers: a united approach for secondary tricuspid regurgitation [PDF]

open access: yesEuropean Heart Journal, 2021
Abstract Background Secondary tricuspid regurgitation (STR) is frequent among patients with heart failure with reduced ejection fraction (HFrEF), however inheres considerable diagnostic challenges. The assessment of circulating biomarkers reflecting neurohumoral activation may constitute a valuable ...
