Tricuspidization of the Quadricuspid Aortic Valve

The Annals of Thoracic Surgery, 2008
Quadricuspid aortic valves represent an uncommon congenital abnormality. Patients may have aortic regurgitation and become symptomatic at a younger age than patients with other types of aortic valve anatomy. We report 3 patients who underwent successful repair by tricuspidization of the aortic valve.

Tricuspidization of the quadricuspid aortic valve

Multimedia Manual of Cardio-Thoracic Surgery, 2010
Quadricuspid aortic valve anatomy is an uncommon congenital anomaly. Patients develop relevant aortic regurgitation in the 4th and 5th decade of life. Reconstruction is possible, and we recommend conversion to a tricuspid configuration.

Comparison of patients with bicuspid and tricuspid aortic valve in transcatheter aortic valve implantation

Expert Review of Medical Devices, 2023
Transcatheter aortic valve implantation (TAVI) has emerged as a safe and effective alternative to surgery for aortic stenosis (AS). However, there are still differences in the procedural process and outcome of bicuspid aortic valve (BAV) treated with TAVI compared with tricuspid aortic valve.This review paper aims to summarize the main characteristics ...

Tricuspid Leaflet Aortic Valve Prosthesis

Circulation, 1966
The theoretical and practical advantages of the flexible-leaflet prosthetic aortic valve make it worthy of continued development. Laboratory and clinical experience with a precision-molded, single-unit, tricuspid silicone rubber prosthesis suggest that the problems of materials, construction, and performance have been overcome.

Bicuspid aortic valve durability with valve-sparing aortic root replacement: comparison to tricuspid valve

European Journal of Cardio-Thoracic Surgery, 2023
Abstract Figure created with BioRender.com. OBJECTIVES Outcomes beyond 10 years for David V valve-sparing aortic root replacement (VSARR) in bicuspid aortic valve (BAV) patients have yet to be explored.

Tricuspid Aortic Valve

2019
Aortic valve replacement (AVR) is applied as a surgical treatment for aortic valve regurgitation (AR), and if root enlargement is seen, aortic root replacement is performed. The results of these procedures are acceptable, but problems can arise from the implanted artificial valve.

Mitral, tricuspid, and aortic valve repair or reconstruction

Current Opinion in Cardiology, 1997
The term repair is most properly applied to disease affecting the mitral and tricuspid valves or their annuli. The rationale, description, and analyses of the most recent evolution in these repair techniques are reviewed. The aortic valve cannot easily be repaired in the true sense of the word.

Tricuspidization of the Bicuspid Aortic Valve With Aortic Regurgitation

The Annals of Thoracic Surgery
To describe the technique of tricuspidization of the bicuspid aortic valve.Six patients with very asymmetrical aortic cusp and 3 sinuses had tricuspidization. Mean age was 32.2 years, and all had severe aortic regurgitation (AR). The fused valve was right + left in 5, and right + noncoronary cusp in 1; commissure angle of the non-fused cusp was 130 ...

Aortic Root Remodeling in the Tricuspid Aortic Valve

The Annals of Thoracic Surgery
Aortic root remodeling is one of the principal forms of valve-preserving root replacement. Its value has been questioned by some, whereas others have achieved excellent valve durability. The purpose of this review is to summarize the existing information to determine which factors may have contributed both to failures and to successes.Publications on ...

Aortic Valve Reconstruction of Unicuspid Aortic Valve by Tricuspidization Using Autologous Pericardium

The Annals of Thoracic Surgery, 2012
Unicuspid aortic valve is a rare anatomic variant, but patients may require intervention for severe valve dysfunction at a young age. We introduce a new reconstructive technique for diseased unicuspid valve by tricuspidization with glutaraldehyde-treated autologous pericardium.From April 2007 through January 2011, we performed 304 cases of aortic valve
