Patient-specific image-based computer simulation for theprediction of valve morphology and calcium displacement after TAVI with the Medtronic CoreValve and the Edwards SAPIEN valve [PDF]

, 2016
AIMS: Our aim was to validate patient-specific software integrating baseline anatomy and biomechanical properties of both the aortic root and valve for the prediction of valve morphology and aortic leaflet calcium displacement after TAVI.

Presence Of A Congenitally Bicuspid Aortic Valve Among Patients Having Combined Mitral And Aortic Valve Replacement [PDF]

, 2012
Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent.

Q-fever prosthetic valve endocarditis in a patient with SLE and antiphospholipid antibody syndrome

Journal of Infection and Public Health, 2020
Q fever prosthetic valve endocarditis in association with antiphospholipid antibody syndrome (APS) in systemic lupus erythematosus (SLE) has not been previously reported. Here, we report a 22-year-old Saudi female diagnosed with SLE and APS.

Transcatheter Aortic Valve Implantation in Dialysis Patients [PDF]

, 2012
Background/Aims: Transcatheter aortic valve implantation (TAVI) has emerged as a new therapeutic option for high-risk patients. However, dialysis patients were excluded from all previous studies.

Annular and supra-annular structure assessments for transcatheter aortic valve replacement in patients with bicuspid aortic stenosis

Reviews in Cardiovascular Medicine, 2021
The clinical use indications for transcatheter aortic valve replacement (TAVR) for the treatment of severe symptomatic aortic stenosis (AS) have expanded from patients at high surgical risk to those at low risk based on the results of multiple large ...

Preoperative aortic annulus size assessment by transthoracic echocardiography compared to the size of surgically implanted aortic prostheses

Echo Research and Practice, 2019
Objectives: The aortic annulus diameter measured by transthoracic echocardiography yields lower values than by computed tomography, and echo-based selection of transcatheter aortic valve prosthesis size has been implied to result in more frequent ...

Left atrial anomalous muscular band as incidental finding during video-assisted mitral surgery [PDF]

, 2018
Congenital fibromuscular bands have been described inleft ventricle or right atrium and have been diagnosed by echocardiography and CT scan. The first report of anomalous band in the left atrium was described in 1897 by Rollestone (1).
