Mechanistic Insights Into How Rewiring and Bifurcation Angle Affect DK‐Crush Stent Deployment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Double kissing crush (DKC) is a preferred two‐stent technique for complex coronary bifurcation lesions. Proximal cell rewiring is routinely recommended to reduce technical failure, and DKC is considered effective across various bifurcation angles. However, it remains unclear whether this standard approach is optimal for all patients.

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 ...

Ex vivo and in vivo coronary ostial locations in humans [PDF]

, 2018
Purpose: Knowledge of the normal in vivo distribution and variation of coronary ostial locations is essential in the planning of various interventional and surgical procedures. However, all studies to date have reported the distribution of coronary ostia

Modified valve-sparing reimplantation technique for para-commissural coronary ostia [PDF]

European Journal of Cardio-Thoracic Surgery, 2013
In some patients undergoing a valve-sparing reimplantation technique, a coronary ostium may be very close to one of the commissures. This condition jeopardizes the coronary ostium patency and valve reimplantation. The authors describe a simple and safe modification of the reimplantation technique, leaving the misplaced coronary ostium attached to the ...

Feasibility and Safety of the ETcath200 Robotic PCI System for Complex Coronary Lesions: A Prospective Single‐Center Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background International robotic‐assisted PCI platforms such as CorPath 200 and CorPath GRX have demonstrated procedural safety and efficacy but are limited by the absence of real‐time tactile feedback and cumbersome device exchange. The ETcath200, the first domestically developed robotic PCI system in China, introduces guidewire force‐sensing

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.

Prevalence of left atrial abnormalities in atrial fibrillation versus normal sinus patients [PDF]

, 2016
BACKGROUND: Atrial fibrillation (AF) may be the cause or sequela of left atrial abnormalities and variants. PURPOSE: To determine the prevalence of left atrial (LA) abnormalities in AF patients compared to normal sinus rhythm (NSR) patients.

Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

Takayasu's Arteritis Involving the Ostia of Three Large Coronary Arteries [PDF]

Korean Circulation Journal, 2009
Takayasu's arteritis can involve the ostia of coronary arteries. We report a patient with Takayasu's arteritis involving the ostia of three large coronary arteries who was successfully treated by percutaneous coronary intervention (PCI) with a drug-eluting stent (DES) and had a good clinical outcome after 12 months.
