Chimney grafts in renal arteries: a clinical model for coronary perfusion in future transcatheter aortic root repair techniques

Journal of Cardiothoracic Surgery, 2020
Objectives Given the similarities between coronary ostia and renal arteries, chimney grafts (CG) for kidney perfusion during abdominal endovascular aneurysm repair (EVAR) can be considered for coronary perfusion in future transcatheter aortic root repair

Aortic insufficiency in a patient with a quadricuspid aortic valve and abnormal left coronary ostium

Journal of the Practice of Cardiovascular Sciences, 2016
A 64-year-old female had symptomatic severe aortic insufficiency and was taken up for aortic valve replacement. The patient was found to have a quadricuspid aortic valve and abnormally located early bifurcated left coronary ostium which were very near to

Surgical removal of an exceedingly rare papillary fibroelastoma of the aortic wall causing unstable angina

Clinical Case Reports, 2021
Difficult diagnosis is due to rarity of the case. TT or TE echocardiography is sufficient to make a correct diagnosis. The risk of embolism or coronary ostia occlusion should guide the decision for surgery.

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.

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.

Morphometry of the heart orifices and morphometry and topography of the coronary ostia in the goat

Folia Morphologica
BACKGROUND: The coronary vessels have been described in various species of domestic and wild ruminants. However, no studies on the detailed morphology and morphometry of heart orifices and coronary ostia in the Polish goat are available.

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 ...

Left Main Stem Perforation: Management Strategies in a Potentially Catastrophic Event

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Left main stem coronary perforation is a potentially fatal complication of percutaneous coronary intervention if not recognized early and treated emergently. Treating left main stem perforation can be challenging due to the significant hemodynamic effect of one of the important steps, namely balloon tamponade.

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.
