The Predictive Value of Quantitative Flow Ratio and Its Derived Angiographic Microvascular Resistance for Restenosis Following Drug‐Coated Balloon Angioplasty

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Initially, drug‐coated balloon (DCB) angioplasty was primarily employed for in‐stent restenosis (ISR) treatment. Over time, its indications have broadened to include de novo small‐vessel lesions and bifurcation lesions. However, there is a lack of effective strategies to reduce restenosis rates post‐DCB angioplasty.

Cost‐Utility Analysis of Different Treatment Modalities in Patients Undergoing Percutaneous Coronary Intervention: Thai PCI Registry

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Cost‐utility analyses of percutaneous coronary interventions (PCIs) provide valuable insights into the economic value of these procedures. However, data is lacking, particularly in developing countries with limited resources. Aims This analysis aimed to compare the cost‐utility of different treatment modalities used for PCI patients
