Catheter Ablation: Evolution and Efficiencies

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT The present review includes a discussion the goals and pitfalls of efficiency in the medical profession, a historical perspective on the evolution of catheter ablation in the field of electrophysiology (EP), and the data regarding the relationship between efficiency and outcomes in the EP lab. Focus on efficacy is critical to maximize resource

Late‐Onset Suspected Coronary Vasospasm Following Focal Monopolar Pulsed‐Field Ablation for Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Coronary vasospasm is a recognized complication of pulsed‐field ablation (PFA), but delayed events are rarely described. Methods and Results A 64‐year‐old man underwent atrial fibrillation ablation using a focal monopolar PFA catheter.

Sudden cardiac arrest due to coronary vasospasm in a patient with Wolff-Parkinson-White syndrome during brain surgery: a case report

JA Clinical Reports, 2019
Background Wolff-Parkinson-White (WPW) syndrome has the risk of sudden cardiac death. Without appropriate treatment, coronary vasospasm is also a potentially fatal condition due to ischemia-induced ventricular fibrillation.

A microstructurally motivated framework to study autoregulation in the coronary circulation

The Journal of Physiology, EarlyView.
Abstract figure legend A microstructurally motivated framework was constructed to simulate coronary autoregulation in symmetrically bifurcating trees at three myocardial depths: subepicardial (subepi), midwall and subendocardial (subendo). Wall mechanics of individual vessels are governed by a constrained‐mixture model, incorporating elastin, collagen ...

An unusual cause of ST elevation: Coronary vasospasm complicating acute myocarditis - A case report and review of the literature

Journal of Clinical and Preventive Cardiology, 2016
Coronary vasospasm and myocarditis are both recognized mimics of ST elevation myocardial infarction with normal coronary arteries. The occurrence of both pathologies in the same patient has rarely been described.

A New Insight Into the Pathogenesis of Coronary Vasospasm [PDF]

Circulation Research, 2006
See related article, pages 682–689 To elucidate the control mechanisms of coronary vascular tone is one of the central interests in cardiac pathophysiology, because ischemic heart disease is one of the major causes of death in many countries. Although the coronary vascular tone is finally determined by the contractile state of smooth muscle, exo ...

Cangrelor Bridge for Repeat Cesarean After Third Trimester Percutaneous Coronary Intervention for Total Occlusion NSTEMI

Clinical Case Reports, Volume 14, Issue 6, June 2026.
Visual Summary, case timeline of non‐ST‐elevation MI with PCI followed by cangrelor bridge for classical cesarean delivery. ABSTRACT Acute coronary syndrome is an uncommon but potentially life‐threatening complication in pregnancy, and dual antiplatelet therapy presents challenges in patients requiring cesarean delivery.

Cardiac Arrest as the First Manifestation of Single Coronary Artery—Potential Role of FFRCT for Detecting Critical Flow Reduction. A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Single coronary artery may present with life‐threatening ventricular arrhythmias even in the absence of structural heart disease or inducible ischemia. FFR‐CT can detect clinically relevant flow reduction despite normal functional testing, highlighting its potential role in risk stratification in patients with coronary anomalies.
