Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

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

open access: yesCatheterization 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).

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

open access: yesCatheterization 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

open access: yesCatheterization 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 ...

Temporal Trends and Prognosis in Rotational Atherectomy: A Comparison of Contemporary and Traditional Eras

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Rotational atherectomy (RA) has undergone considerable technical modernization in recent years. This study evaluated whether RA performed in the contemporary era was associated with superior cardiovascular outcomes compared with the traditional era. Aims To compare the clinical characteristics and cardiovascular outcomes of patients
