Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.

Advancements and Perspectives in the Bioprosthetic Heart Valve: A Comprehensive Review on Biomaterial Processing and Emerging Polymeric Materials

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Heart valve disease contributes to cardiovascular disease–associated death. Bioprosthetic heart valves have emerged as a preferred option for heart valve replacement due to their superior hemodynamic performance and reduced need for lifelong ...

Transcatheter Tricuspid Valve Replacement for Residual Tricuspid Regurgitation After TEER

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Residual or recurrent tricuspid regurgitation (TR) after prior transcatheter tricuspid edge‐to‐edge (T‐TEER) repair occurs in about 12% of patients within 1 year. Since surgical tricuspid valve repair or replacement is of high risk, treatment options remain scarce.

Preclinical Testing of Living Tissue-Engineered Heart Valves for Pediatric Patients, Challenges and Opportunities

Frontiers in Cardiovascular Medicine, 2021
Introduction: Pediatric patients with cardiac congenital diseases require heart valve implants that can grow with their natural somatic increase in size. Current artificial valves perform poorly in children and cannot grow; thus, living-tissue-engineered

Perioperative anticoagulation for children with prosthetic mechanical valves [PDF]

, 2000
The insertion of a mechanical heart valve predisposes to thrombosis and embolism, and for this reason, individuals with mechanical valves who undergo dental/surgical procedures must take special precautions.

Clinical Outcomes of the Allegra Transcatheter System in Bioprosthetic Aortic Valve Failure: A Multicentre Valve‐in‐Valve Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Introduction The prevalence of bioprosthetic aortic valve failure is increasing due to the broader use of bioprosthetic valves, both surgical and transcatheter, and an ageing population. Registry data indicate a higher risk of coronary obstruction and elevated gradients following valve‐in‐valve transcatheter aortic valve implantation (TAVI ...
