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 ...

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...

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).

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.

Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

Normal fractional flow reserve with a critical stenosis supplying viable myocardium.

, 2012
A high-grade stenosis to viable myocardium typically produces a positive fractional flow reserve. In the present report, a case of subtotal occlusion of a saphenous vein graft to a viable myocardial territory with normal fractional flow reserve is ...

Clinical Outcomes of Drug‐Eluting Stents and Drug‐Coated Balloons in Tortuous Small Coronary Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In small, tortuous coronary lesions, the long‐term comparative performance of drug‐coated balloon (DCB) angioplasty versus drug‐eluting stent (DES) treatment remains uncertain, despite both strategies being widely used in contemporary percutaneous coronary intervention (PCI) practice. Aims This study aimed to compare 3‐year clinical

Evaluating the Impact of Enhanced Stent Visualization on PCI Outcomes in Older Patients With Multivessel Disease

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Optimal stent expansion is a key determinant of long‐term outcomes after PCI. Intravascular imaging provides the most accurate assessment of stent deployment but remains underused, especially in older patients with MI and multivessel disease.
