Tackling distal left main bifurcation disease lurking behind a patient of Wellens’ syndrome

IHJ Cardiovascular Case Reports, 2020
This is the first report to the best of my knowledge describing a patient with Wellens’ syndrome having chest pain accompanied by bifid T waves in precordial leads without significant ST segment elevation or Q waves in the electrocardiogram, and ...

Safety of mapping in the sinus of valsalva region under intracardiac echocardiography guidance without angiography

Indian Pacing and Electrophysiology Journal, 2021
Background: Radiofrequency ablation at the region of the sinus of Valsalva carries a risk to the ostia of the coronary arteries. Coronary angiography is usually utilized to document a safe distance for mapping and ablation.

Cerebrovascular Events in Aortic Stenosis: From Native Valve Disease to TAVR‐Specific Risk and Prevention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.

Hemodynamic Significance of APEXCT Coronary Angiography Combined With Dynamic CT Myocardial Perfusion Imaging in Assessing Restenosis After Coronary Stenting

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the hemodynamic significance of in‐stent restenosis (ISR) by using a combined anatomical‐functional approach with photon‐counting CT coronary angiography (APEX‐CT CTA) and dynamic CT myocardial perfusion imaging (CT‐MPI). We prospectively enrolled 239 symptomatic patients at least 9 months after PCI.

Absence of Right Coronary Ostium with Single Coronary Artery: A Rare Anomaly

Methodist DeBakey Cardiovascular Journal
Coronary arteries normally originate from two separate cusps from the aorta, and various anomalies can occur. One such anomaly is the single coronary artery (SCA), where the coronary arteries originate from a single ostium due to the absence of the ...

Reverse extra-anatomic aortic arch debranching procedure allowing thoracic endovascular aortic repair of a chronic ascending aortic aneurysm

Journal of Vascular Surgery Cases and Innovative Techniques, 2018
A 79-year-old woman was admitted with a large chronic dissecting ascending aortic aneurysm starting 5 mm distal to the ostia of the left coronary artery and ending immediately proximal to the innominate artery.

Morphometric Assessment for Functional Evaluation of Coronary Stenosis With Intravascular Ultrasound and Ultrasonic Flow Ratio in Vessels With a Single Stenosis

Medicine Advances, EarlyView.
This developed a morphometric assessment for functional evaluation of coronary stenosis with intravascular ultrasound and ultrasonic flow ratio in vessels with single stenosis; the results demonstrated ultrasonic flow ratio (UFR) has a good correlation with the Murray law‐based quantitative flow ratio (uQFR).

A Rare and Lethal Ostial Left Main Trunk Lesion: A Case Report

Cardiology Discovery, 2022
. Coronary artery involvement in cardiovascular syphilis is infrequent and often overlooked, especially in patients with latent syphilis. Herein, we present the case of myocardial infarction largely related to cardiovascular syphilis in a 63-year-old man.

Diltiazem N‐oxide, a novel ischaemia‐activated prodrug, prevents ischaemia‐induced ventricular fibrillation without off‐target adverse effects

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ventricular fibrillation (VF) in coronary heart disease accounts for up to 70% of sudden cardiac death. We examined whether diltiazem N‐oxide (DNO) has ischaemia‐selective antiarrhythmic activity. Experimental Approach Randomised and blinded experiments were performed in rat isolated hearts and in anaesthetised rats to ...
