Natural biomaterials in the management of the aortic valve pathology. Biomedical and clinical aspects: A review

Biomolecules & Biomedicine
Heart valve diseases are a prevalent cardiovascular pathology worldwide, affecting nearly 2.5% of the population. Degenerative aortic stenosis is the most common form of heart valve disease.

Less Symptom Improvement in Patients Undergoing TAVI With Concomitant COPD, Atrial Fibrillation and Heart Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Comorbidities like a history of chronic obstructive pulmonary disease (COPD), atrial fibrillation (AF) and heart failure (HF) can cause similar symptoms as aortic stenosis (AS). However, how they influence symptom improvement and long‐term outcomes after transcatheter aortic valve implantation (TAVI) is unclear.

Aortic root enlargement does not increase the surgical risk and short-term patient outcome [PDF]

, 2011
Objective: To analyze the short-term outcome of aortic root enlargement (ARE) using death and adverse events as end points. Methods: From January 1999 through December 2009, 3339 patients were subjected to aortic valve replacement (AVR).

Comparison of Latest Generation Intra‐ and Supra‐Annular Self‐Expanding Transcatheter Heart Valves for Aortic Valve‐in‐Valve Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Valve‐in‐valve (ViV) procedures are an established therapy. Self‐expanding (SE) supra‐annular transcatheter heart valves (THV) achieve superior hemodynamics compared to balloon‐expandable (BE) intra‐annular THV, but influence of stent design versus valve position remains unclear.

Transcatheter Aortic Valve Implantation in a Ross Procedure Patient With Severe Autograft Regurgitation: A Case Report

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Surgical aortic valve replacement (AVR) is the standard treatment for symptomatic severe neo‐aortic regurgitation in Ross patients. The only previous report of a transcatheter aortic valve implantation (TAVI) in a Ross patient required valve‐in‐valve rescue. Thus, this is the first uncomplicated TAVI procedure in a Ross patient.
