Abstract
Transcatheter mitral valve-in-valve implantation is a preferred treatment for degenerating mitral bioprosthetic valves in high-risk surgical patients. A balloon-expandable transcatheter heart valve delivered through a postero-inferior transseptal puncture is deployed within the prosthesis over a guidewire secured in the left ventricle. Patients with aneurysmal left atrium and altered angulation between the planes of atrial septum and mitral prosthesis have unstable position of the guidewire that flips out of the left ventricle into the left atrium when the valve delivery system is advanced. Instead of a transapical access to snare the guidewire and create a railroad in such instances, we report a new technique of transarterial retrograde snaring of the guidewire in the left ventricle for stabilization.
期刊介绍：
Catheterization and Cardiovascular Interventions is an international journal covering the broad field of cardiovascular diseases. Subject material includes basic and clinical information that is derived from or related to invasive and interventional coronary or peripheral vascular techniques. The journal focuses on material that will be of immediate practical value to physicians providing patient care in the clinical laboratory setting. To accomplish this, the journal publishes Preliminary Reports and Work In Progress articles that complement the traditional Original Studies, Case Reports, and Comprehensive Reviews. Perspective and insight concerning controversial subjects and evolving technologies are provided regularly through Editorial Commentaries furnished by members of the Editorial Board and other experts. Articles are subject to double-blind peer review and complete editorial evaluation prior to any decision regarding acceptability.
