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-

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.

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-

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

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 ...

Postinterventional fetal aortic regurgitation: prevalence, outcome and effects on fetal circulation in large single‐center cohort [PDF]
Ultrasound in Obstetrics & GynecologyABSTRACTObjectivesTo analyze the prevalence and severity of fetal aortic regurgitation (AR) after undergoing successful 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 successful FAV at our

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

Echocardiographic assessment of the right heart pulmonary circulation unit in mitral regurgitation due to mitral valve prolapse [PDF]
European Heart JournalAbstract Background Right ventricular evaluation is essential in the context of chronic mitral regurgitation (MR). Chronic MR is associated with a progressive cardiac remodeling with enlargement and dysfunction of all cardiac chambers, and the development of functional tricuspid regurgitation (TR ...

In degenerative mitral regurgitation a combined speckle tracking analysis predicts right ventricular to pulmonary circulation uncoupling [PDF]
European Heart Journal - Cardiovascular ImagingAbstract Background Global Longitudinal Strain (GLS) and left atrial (LA) strain evaluation by Speckle Tracking Echocardiography (STE) have emerged as prognostic index in patients affected by degenerative mitral regurgitation (DMR). In this setting, the coupling between right ventricular (RV) function
