A tissue-silicone integrated simulator for right ventricular pulsatile circulation with severe functional tricuspid regurgitation [PDF]

Scientific Reports
AbstractThere 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-silicone integrated right ventricular pulsatile circulatory simulator.

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.

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, 2016
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

[Coronary collateral circulation and prevention of ischemic mitral regurgitation].

Medicinski pregled, 2000
According to definition, collateral circulation is an alternative to major vascular flow which has become dysfunctional. Collateral channels, initially unused, are being formed due to impossibility of the main blood vessel to provide normal coronary flow.

Quantitative aortography for assessment of aortic regurgitation in the era of percutaneous aortic valve replacement

Frontiers in Cardiovascular Medicine, 2023
Paravalvular leak (PVL) is a shortcoming that can erode the clinical benefits of transcatheter valve replacement (TAVR) and therefore a readily applicable method (aortography) to quantitate PVL objectively and accurately in the interventional suite is ...
