Quadricuspid aortic valve not discovered by transthoracic echocardiography

Cardiovascular Ultrasound, 2006
Background Quadricuspid aortic valve is a rare congenital heart defect. Several different anatomical variations of a quadricuspid aortic valve has been described and aortic regurgitation is the predominant valvular dysfunction associated with ...

Predicting Aortic Regurgitation After Transcatheter Aortic Valve Replacement by Finite Element Method

IEEE Access, 2019
Aortic regurgitation as a severe complication of transcatheter aortic valve replacement (TAVR) is usually due to the aortic valve leaflets that carry severity and inhomogeneous distribution of the calcification.

Evaluating the Portability of an NLP System for Processing Echocardiograms: A Retrospective, Multi-site Observational Study [PDF]

arXiv, 2019
While natural language processing (NLP) of unstructured clinical narratives holds the potential for patient care and clinical research, portability of NLP approaches across multiple sites remains a major challenge. This study investigated the portability of an NLP system developed initially at the Department of Veterans Affairs (VA) to extract 27 key ...

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.

Aortitis as a Rare Cause of Aortic Aneurysm and Valve Regurgitation: Is Repair Precluded?

Case Reports in Cardiology, 2018
Aortitis is an infrequent cause of aortic root dilatation and aortic valve regurgitation. Valve-sparing procedures have been proposed, but there is not clear evidence of which is the treatment of choice.

Iatrogenic non-coronary leaflet perforation as a complication after robotic mitral valve repair

Journal of Cardiothoracic Surgery
Iatrogenic aortic regurgitation secondary to leaflet injury is a rare complication of mitral valve surgery. For the first time, we report a patient who had progressive aortic regurgitation due to non-coronary leaflet perforation after robotic mitral ...

The Challenges of Aortic Valve Management After Left Ventricular Assist Device Implantation

Annals of Thoracic Surgery Short Reports
Background: Continuous retrograde flow across the aortic valve from left ventricular assist device (LVAD) therapy can result in cusp damage and progressive aortic regurgitation, potentially triggering recurrent heart and multiorgan failure.

Three-Dimensional Lagrangian Coherent Structures in Patients with Aortic Regurgitation [PDF]

arXiv
Understanding blood transport in cardiovascular flows is important for managing patients with cardiovascular disease. In this study, three-dimensional Lagrangian coherent structures have been extracted for the first time in both healthy patients and patients with aortic regurgitation.

Pannus-Related Mechanical Valve Dysfunction Leading to Hemodynamic Shock

Archives of Clinical and Experimental Surgery, 2012
Mechanical prosthetic valve dysfunction caused by pannus formation is rare. Pannus restricts movement of prosthetic valve leaflets, resulting in severe aortic regurgitation.
