Quadricuspid Aortic Valve: A Rare Congenital Anomaly [PDF]

Journal of Clinical and Diagnostic Research, 2018
Quadricuspid Aortic Valve (QAV) is a rare, but well-recognised congenital anomaly, which may result in significant aortic regurgitation. We report a case of asymptomatic young male who was inadvertently diagnosed with QAV with moderately severe aortic ...

Clinical features of quadricuspid aortic valve in middle‐aged and elderly patients: Insights from a regional study

Echocardiography, Volume 41, Issue 4, April 2024.
In patient over 45 years old, quadricuspid aortic valve (QAV) was identified in 0.032% of our cohort. Patients diagnosed with QAV after middle age, who do not exhibit severe valve insufficiency at the time of diagnosis, may not experience worse clinical outcomes. Abstract Background Quadricuspid aortic valve (QAV) is a rare congenital disease.

Imaging of Cardiac Valves by Computed Tomography

Scientifica, Volume 2013, Issue 1, 2013., 2013
This paper describes “how to” examine cardiac valves with computed tomography, the normal, diseased valves, and prosthetic valves. A review of current scientific literature is provided. Firstly, technical basics, “how to” perform and optimize a multislice CT scan and “how to” interpret valves on CT images are outlined.

Quadricuspid Aortic Valve: Three Cases Report and Literature Review [PDF]

Brazilian Journal of Cardiovascular Surgery, 2019
Quadricuspid aortic valve (QAV) is a rare cardiac malformation. Many cases are incidentally diagnosed in aortic surgeries or autopsies and it usually appears as an isolated anomaly. The most widely classification used is the one by Hurwitz and Roberts[1],

Bicuspid Aortic Valve and Thoracic Aortic Aneurysm: Three Patient Populations, Two Disease Phenotypes, and One Shared Genotype

Cardiology Research and Practice, Volume 2012, Issue 1, 2012., 2012
Bicuspid aortic valve (BAV) and thoracic aortic aneurysm (TAA) are two discrete cardiovascular phenotypes characterized by latent progressive disease states. There is a clear association between BAV and TAA; however the nature and extent of this relationship is unclear.

Trans-apical aortic valve implantation for quadricuspid aortic valve with aortic regurgitation using J-valve system: a case reports

Journal of Cardiothoracic Surgery, 2021
Background Quadricuspid aortic valve (QAV) is a rare congenital heart defect usually accompanied with different hemodynamic abnormalities. Due to the rarity of QAV, treatment and prognosis of QAV patients with aortic regurgitation still remain ...

A Design-Based Model of the Aortic Valve for Fluid-Structure Interaction [PDF]

, 2020
This paper presents a new method for modeling the mechanics of the aortic valve, and simulates its interaction with blood. As much as possible, the model construction is based on first principles, but such that the model is consistent with experimental observations.

Rare Anatomic Entity Of Quadricuspid Aortic Valve With Aortic Insufficiency: A Case Report

Kaohsiung Journal of Medical Sciences, 2007
Quadricuspid aortic valve (QAV) is a rare congenital heart defect that often causes symptomatic aortic insufficiency in adulthood, imposing valve replacement. Herein, we describe one unusual case of QAV which underwent valve replacement uneventfully.
