Strategic aortic root enlargement for patients with a small aortic annulus in the era of transcatheter aortic valve-in-surgical aortic valve procedures.

Transcatheter Aortic Valve-in-Surgical Aortic Valve (TAV-in-SAV) for Structural Valve Degeneration of Post-Surgical Aortic Valve Replacement (SAVR) With the 3D-Nicks Procedure: A Case Report

Transcatheter aortic valve implantation (TAVI) for structural valve deterioration (SVD) following surgical aortic valve replacement (SAVR) is an established alternative to redo surgery (transcatheter aortic valve-in-surgical aortic valve, or TAV-in-SAV). However, in patients with a small aortic annulus or small sinus o...

CT-Guided Transcatheter Aortic Valve Replacement in Bicuspid Aortic Stenosis With a Large Membranous Ventricular Septal Aneurysm: Challenges in Annular Sizing and Valve Selection.

Membranous ventricular septal aneurysm (MSA) is an uncommon anatomical finding that may significantly alter the geometry of the aortic annulus and left ventricular outflow tract, creating challenges for transcatheter aortic valve replacement (TAVR). We report the case of a 78-year-old woman with symptomatic severe bicu...

Landmark-based low implantation using a balloon-expandable valve to avoid sinus sequestration during redo transcatheter aortic valve implantation: a case report

Redo transcatheter aortic valve implantation (TAVI) is increasingly performed for structural valve deterioration of transcatheter heart valves. Sinus sequestration is a mechanism of coronary obstruction in which displaced leaflets of the index transcatheter valve isolate the coronary sinus from the aortic root af...

Transcatheter aortic valve-in-valve implantation for failed surgical aortic bioprostheses using the Navitor platform: early outcomes in a consecutive single-center cohort

Introduction Transcatheter heart valve implantation into a failed surgical heart valve (THV-in-SHV) is an established reintervention strategy for degenerated aortic bioprostheses; however, early procedural outcomes, discharge hemodynamics, and standardized safety remain clinically relevant in routine practice. Material...

Quantitative computed tomographic assessment of aortic root geometry after Y-incision aortic root enlargement in patients with small aortic annuli.

Y-incision aortic annular enlargement using the arc patch modification: a step-by-step tutorial.

Aortic annular enlargement is an important adjunct to aortic valve replacement in patients with a small aortic annulus and restricted aortic root anatomy. The Y-incision technique facilitates implantation of a larger prosthetic valve, reducing the risk of prosthesis-patient mismatch and improving postoperative haemodyn...
