Transcatheter Edge-to-Edge Repair of Common Atrioventricular Valve Regurgitation in the Setting of a Lateral Tunnel Fontan Circulation [PDF]
Structural Heart• Percutaneous repair of severely regurgitant atrioventricular valves in the setting of a Fontan circulation utilizing Tri-Clip, even in the setting of an atrioventricular septal defect, is feasible. • Percutaneous options hold promise as a low-risk repair strategy in this highly complex population, which generally has a high surgical risk.

A tissue-silicone integrated simulator for right ventricular pulsatile circulation with severe functional tricuspid regurgitation [PDF]
Scientific ReportsThere is a great demand for development of a functional tricuspid regurgitation (FTR) model for accelerating development and preclinical study of tricuspid interventional repair devices. This study aimed to develop a severe FTR model by creating a tissue-

Postinterventional fetal aortic regurgitation: prevalence, outcome and effects on fetal circulation in large single‐center cohort [PDF]
Ultrasound Obstet GynecolABSTRACTObjectivesTo analyze the prevalence and severity of fetal aortic regurgitation (AR) after undergoing fetal aortic valvuloplasty (FAV) and to evaluate its effects on fetal circulation and left ventricular (LV) growth.MethodsThis was a retrospective review of all fetuses with critical aortic stenosis who underwent FAV at our center between 2010 ...

JACC: 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-

Computational fluid dynamics modelling of left valvular heart diseases during atrial fibrillation [PDF]
PeerJ, 2016 Background: Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood.

Abolished ischemic tricuspid regurgitation by revascularization of left anterior descending artery: The role of collateral circulation [PDF]
Journal of Cardiology Cases, 2014 AbstractA 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.

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

Predicting ischemic mitral regurgitation in patients with acute ST-elevation myocardial infarction: Does time to reperfusion really matter and what is the role of collateral circulation? [PDF]
International Journal of Cardiology, 2015 Ischemic mitral regurgitation (MR) is an adverse prognostic factor. We aimed to assess the role of time delay from symptom onset to reperfusion, and the impact of collateral circulation to incidence of MR in relation to established echocardiographic and clinical risk factors.Patients with STEMI presenting within 12 h from symptom onset and treated with
