Precision and Accuracy of Dimensional Assessment of Luminal Contours by Commercially Available Quantitative Angiography Software as a Prerequisite to Angiography Based FFR and Other Derived Parametrics

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Accurate dimensional measurements are critical for quantitative coronary angiography (QCA) and serve as the first step in angiography‐based fractional flow reserve (FFR) calculations. Aims To compare minimum lumen diameter (MLD) measurements across multiple QCA or anigo‐based FFR software programs using phantom models.

Outcomes Beyond 10 Years After Transcatheter Aortic Valve Implantation in High‐Risk Patients With Severe Aortic Valve Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Limited data is available on long‐term outcomes and valve durability measures of transcatheter aortic valve implantation (TAVI). Aims This study sought to assess clinical and echocardiographic outcomes of high‐risk patients during the early experience of TAVI with a follow‐up period extending beyond 10 years.

Impact of coronary revascularization on coronary flow capacity measured by transthoracic Doppler echocardiography in patients with chronic coronary syndrome

Scientific Reports
Coronary flow capacity (CFC) integrates quantitative assessment of hyperemic myocardial blood flow and coronary flow reserve. We aimed to evaluate the effect of elective percutaneous coronary revascularization (PCI) on CFC using serial stress ...

An Euroheart‐Based Percutaneous Coronary Intervention Registry in Vietnam: Design, Rationale, and Preliminary Results

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background As a cardiac interventional procedure, percutaneous coronary intervention (PCI) is increasingly becoming the most widely adopted across the globe. With increasing implementation in practice, the use of PCI registries to evaluate safety and effectiveness has grown internationally.

Intravascular Lithotripsy for Calcific Coronary Bifurcations: Procedural Success and 1‐Year Clinical Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) has emerged as a promising treatment for heavily calcified coronary lesions. However, evidence regarding its effectiveness in calcific bifurcation lesions remains limited. Objective We aimed to evaluate the technical success and 1‐year clinical outcomes of IVL in calcified coronary bifurcation lesions.

Functional assessment of coronary artery disease by intravascular ultrasound and computational fluid dynamics simulation

Revista Portuguesa de Cardiologia, 2014
Clinical trials have shown that functional assessment of coronary stenosis by fractional flow reserve (FFR) improves clinical outcomes. Intravascular ultrasound (IVUS) complements conventional angiography, and is a powerful tool to assess atherosclerotic

Comparison of Latest Generation Intra‐ and Supra‐Annular Self‐Expanding Transcatheter Heart Valves for Aortic Valve‐in‐Valve Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Valve‐in‐valve (ViV) procedures are an established therapy. Self‐expanding (SE) supra‐annular transcatheter heart valves (THV) achieve superior hemodynamics compared to balloon‐expandable (BE) intra‐annular THV, but influence of stent design versus valve position remains unclear.

Breaking the Barrier: Unraveling the No‐Reflow Phenomenon in Cardiovascular Medicine

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The no‐reflow phenomenon is a stubborn and often devastating complication in cardiovascular medicine, where blood flow is restored to an artery, yet the microvasculature remains unresponsive. First identified in 1967, this phenomenon has haunted clinicians and researchers alike, particularly in the context of acute myocardial infarction (AMI).
