Impact of Elevated Preprocedural Left Ventricular Filling Pressure on Prognosis of Mild Paravalvular Regurgitation Following Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) is a complication linked to poor outcomes. The prognostic impact of mild PVR, particularly in patients with elevated preprocedural left ventricular (LV) filling pressure, remains uncertain.

Diagnostic Accuracy of Angiography‐Derived Murray Law‐Based Quantitative Flow Ratio (μQFR) Versus Pressure‐Derived Fractional Flow Reserve (FFR) in Moderate to Severe Calcified Coronary Lesions—The DIAMOND Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based Quantitative Flow Ratio (μQFR) is an innovative AI‐driven method for evaluating coronary lesions using contrast flow velocity estimates. Unlike traditional approaches, μQFR does not require pressure wires or hyperemia induction.

Twin heart with a fused atria and separate ventricles in conjoined twins

Annals of Pediatric Cardiology, 2010
One of the most interesting congenital malformations is that of conjoined twins. We report echocardiographic features of twin heart in dicephalus, tribrachius, dispinous, thoracoomphalopagus twin. It showed two hearts fused at atrial level.

Optimizing Medication Decisions for Patients with Atrial Fibrillation through Path Development Network [PDF]

arXiv
Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by rapid and irregular contractions of the atria. It significantly elevates the risk of strokes due to slowed blood flow in the atria, especially in the left atrial appendage, which is prone to blood clot formation.

A Rare Case of Nitroglycerin Resistant Coronary Arterial Vasospasm During Coronary Artery Bypass Surgery

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary artery vasospasm following coronary artery bypass grafting (CABG) is a rare but potentially life‐threatening complication that can lead to myocardial ischemia, arrhythmias, and cardiogenic shock. Nitroglycerin‐resistant vasospasm, particularly involving the left main coronary artery (LMCA), poses significant diagnostic and ...
