MORPHOLOGICAL STUDY OF CORONARY OSTIA

International Journal of Advanced Research, 2020
Objective: To study the normal and variant anatomy of the coronary artery ostia in south Indian population. Introduction: Sudden cardiac deaths, especially in young are on the rise in recent days. Of all causes for sudden cardiac death, anomalous origins of coronary arteries also comprise a significant percentage.

Location and Size of Coronary Ostia in Normal Autopsied Hearts at the University Teaching Hospital, Lusaka, Zambia [PDF]

, 2016
Background: Coronary ostia are orifices located in the aortic sinuses from which coronary arteries normally arise. Knowledge of their location and size is important in diagnosis and treatment cardiovascular diseases. Materials and methods: A total of 125

Iatrogenic Left Main Coronary Artery Dissection During Non-Left Main Intervention: A Case Series

Indian Journal of Clinical Cardiology, 2023
Iatrogenic left main coronary artery (LMCA) dissection is a rare complication of percutaneous coronary intervention (PCI), it is mainly attributed to the catheter-based manipulation during engagement of Ostia or during the intervention.

Invasive coronary physiology in patients with angina and non-obstructive coronary artery disease: a consensus document from the coronary microvascular dysfunction workstream of the British Heart Foundation/National Institute for Health Research Partnership [PDF]

, 2022
Nearly half of all patients with angina have non-obstructive coronary artery disease (ANOCA); this is an umbrella term comprising heterogeneous vascular disorders, each with disparate pathophysiology and prognosis.

Combination of Double Chimney Technique and Prosthesis Post-Dilation After Valve-in-Valve Implantation

JACC: Case Reports, 2020
Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is an effective treatment for aortic bioprosthetic valve degeneration. ViV-TAVI could lead to coronary occlusion.

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Transcatheter Aortic Valve Implantation Assisted with Microcatheter: A New Method to Avoid Coronary Artery Obstruction

Chinese Medical Journal, 2015
Background: Lack of fluoroscopic landmarks can make valve deployment more difficult in patients with absent aortic valve (AV) calcification. The goal of this article was to evaluate the feasibility and effectiveness of transcatheter implantation of a ...

Descriptive, stratigraphic, and morpho‐functional study of the myocardium and myocardial bridges in domestic pig hearts

The Anatomical Record, EarlyView.
Abstract The heart is the central organ of the cardiovascular system. The myocardium is composed of a three‐dimensional network of fibers arranged in clockwise and counterclockwise helices, which are essential for proper cardiac contraction. This study aimed to describe the stratigraphic and morpho‐functional pattern of the porcine myocardium to ...

Percutaneous Transaxillary Access for Large‐Bore Cardiovascular Interventions: Evidence, Technique, and Complication Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Percutaneous transaxillary access is an established alternative to transfemoral large‐bore arterial access for transcatheter structural heart interventions and mechanical circulatory support (MCS). Although useful for overcoming hostile iliofemoral anatomy and providing prolonged support and patient mobilization in case of MCS, the axillary ...

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.
