Percutaneous Transaxillary Access for Large‐Bore Cardiovascular Interventions: Evidence, Technique, and Complication Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Percutaneous transaxillary access is an established alternative to transfemoral large‐bore arterial access for transcatheter structural heart interventions and mechanical circulatory support (MCS). Although useful for overcoming hostile iliofemoral anatomy and providing prolonged support and patient mobilization in case of MCS, the axillary ...

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.

Coronary Flow in Hypertrophic Obstructive Cardiomyopathy—Immediate Effects of Alcohol Septal Ablation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Hypertrophic cardiomyopathy is associated with alterations in coronary microvascular function which have variable pathophysiologic mechanisms, and variable reversibility acutely and chronically following alcohol septal ablation (ASA).

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...

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.

Heart valve sound of various mechanical composite grafts, and the impact on patients' quality of life

, 2010
The closing sounds of mechanical heart valves can be disturbing for patients and their closest relatives. Although some investigations into mechanical heart valve sounds have been performed, the particularities of the valve sound when it is attached to a
