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.

Quadricuspid aortic valve diagnosed by transthoracic echocardiography in childhood
The Turkish Journal of Pediatrics, 2010 Quadricuspid aortic valve is a rare congenital malformation of the heart leading to significant aortic regurgitation or stenosis. Its diagnosis by transthoracic echocardiography is difficult.

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.

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2019 Isolated aortic valve stenosis in adults with or without aortic regurgitation is almost always secondary to a congenital valvular malformation. These congenital malformations usually present as a bicuspid, quadricuspid, or unicuspid aortic valve.

Severe aortic regurgitation in a quadricuspid aortic valve: A false rheumatic disease
Clinical Case Reports, 2019 Key Clinical Message The quadricuspid aortic valve (QAV) is a malformation that leads to severe valve failure later in life. Malformation and displacement of coronary ostia are found in 10% of patients.
