A Case of Uncommon Quadricuspid Aortic Valve Stenosis Associated With Noonan Syndrome and Acromegaly
Annals of Internal Medicine: Clinical Cases, 2023 Quadricuspid aortic valve (QAV) is a congenital aortic valve malformation usually associated with aortic regurgitation. We encountered a patient with Noonan syndrome (NS) who had severe QAV stenosis caused by degenerative aortic cusps with an ...

Quadricuspid aortic valve: a rare cause of aortic regurgitation and stenosis
The Turkish Journal of Pediatrics, 2008 Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy.

Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]
arXiv, 2022 Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.

A Rare Congenital Cardiac Anomaly Presenting with Amaurosis Fugax: Quadricuspid Aortic Valve
Haseki Tıp Bülteni, 2014 Quadricuspid aortic valve (QAV) is a rare cause of aortic regurgitation. Most cases are detected incidentally during echocardiography, angiography, autopsy or surgery. It may also be associated with other congenital anomalies of the heart.

Quadricuspid aortic valve with aortic insufficiency: a rare echocardiographic finding [PDF]
, 2020 Introduction: Quadriscupidaortic valve (QAV) is a rare congenital heart defect typically found incidentally without any associated cardiac defects. The functional status of QAV is pure aortic insufficiency (AI), however, clinical manifestations are ...

Development of a patient-specific finite element model of the Transcatheter Aortic Valve Implantation (TAVI) procedure [PDF]
arXiv, 2019 This work reports on a study to develop a patient-specific finite element model of the Transcatheter Aortic Valve Implantation procedure, using a model of a balloon-expandable percutaneous prosthetic aortic valve as a framework for the prediction of its performance.

A new technological system to revolutionize the management of valvular heart diseases: transcatheter aortic valve for the treatment of aortic stenosis [PDF]
arXiv, 2019 The goal of this study is a technology analysis of a revolution for the management of valvular heart diseases given by new technological system based on transcatheter artificial aortic valve, a delivery catheter and a loading system for the treatment of aortic stenosis (a narrowing of the aortic valve because of calcium build up that restricts blood ...
