International Journal of the Cardiovascular Academy, 2016 AbstractCongenital aortic valve cleft is a rare entity with scanty literature available. Cleft in aortic valve can be congenital, degenerative or age related. Sudden rupture of cusps can lead to severe aortic insufficiency requiring surgical intervention.

Stochastic Modelling and Dynamic Analysis of Cardiovascular System with Rotary Left Ventricular Assist Devices [PDF]
Mathematical Problems in Engineering, 2018, 2018 The left ventricular assist device (LVAD) has been used for end-stage heart failure patients as a therapeutic option. The aortic valve plays a critical role in heart failure and its treatment with LVAD. The cardiovascular-LVAD model is often used to investigate the physiological demands required by patients and predict the hemodynamic of the native ...

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]
arXiv, 2018 An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological pulsatile flow.

Anatomical description of malformations of the neck of the left atrial appendage
Clinical Anatomy, EarlyView.Abstract The recently‐described left atrial appendage (LAA) neck is a truncated cone‐shaped structure that connects the LAA orifice to its lobe. It shows malformations in some cases, but their exact description and clinical significance are unknown. Therefore, the aim of this study was to provide a detailed anatomical and morphometric analysis of LAA ...

Experimental investigation of the flow downstream of a dysfunctional bileaflet mechanical aortic valve [PDF]
arXiv, 2019 Mechanical heart valve replacement is the preferred alternative in younger patients with severe symptomatic aortic valve disease. However, thrombus and pannus formations are common complications associated with bileaflet mechanical heart valves. This leads to risks of valve leaflet dysfunction, a life threatening event.

Current Directions in Biomedical Engineering, 2015 Transcatheter aortic valve implantation is a therapy for patients with reduced left ventricular ejection fraction and symptomatic aortic stenosis. The aim of the study was to compare the pre-and post- transcatheter aortic valve implantation procedures to
