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.

Comparing the Role of Mechanical Forces in Vascular and Valvular Calcification Progression

Frontiers in Cardiovascular Medicine, 2019
Calcification is a prevalent disease in most fully developed countries and is predominantly observed in heart valves and nearby vasculature. Calcification of either tissue leads to deterioration and, ultimately, failure causing poor quality of life and ...

Simultaneous Transcatheter Double Valve Treatment of Mediastinal Radiation-Induced Severe Calcific Aortic and Mitral Stenosis

JACC: Case Reports, 2020
Mediastinal radiation-induced severe calcific valve disease carries increased operative mortality. Transcatheter therapies are also challenging and potentially hazardous. We used a unique constellation of imaging and planning technologies to successfully

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 ...

Enhancing aortic valve drug delivery with PAR2-targeting magnetic nano-cargoes for calcification alleviation

Nature Communications
Calcific aortic valve disease is a prevalent cardiovascular disease with no available drugs capable of effectively preventing its progression. Hence, an efficient drug delivery system could serve as a valuable tool in drug screening and potentially ...

Transcriptomic Signatures of Calcific Aortic Valve Stenosis Severity in Human Tricuspid and Bicuspid Aortic Valves

JACC: Basic to Translational Science
Summary: There is currently no medical therapy for calcific aortic valve stenosis. We aimed to identify transcriptomic signatures of the disease severity.

Sheath‐to‐Artery Diameter Ratio: A Robust Predictor of Early Access‐Site Adverse Events in Percutaneous Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Vascular access site complications (VASCs) remain an important source of morbidity following percutaneous interventions. Although the sheath‐to‐femoral artery ratio is a recognized risk factor in transcatheter aortic valve implantation (TAVI), its role across a broader range of femoral procedures is less well defined.

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 ...
