A Case of Acute Left Main Coronary Obstruction Following Transcatheter Aortic Valve Implantation

Neo Left Main Channel Creation Using Double Stenting Alongside a Sapien 3 Aortic Valve Bioprosthesis for Left Main Coronary Obstruction Following Valve-in-Valve Transcatheter Aortic Valve Replacement: A Case Report With Review of Literature

Transcatheter aortic valve replacement in the setting of failed surgical bioprosthesis (valve-in-valve) is a valuable option for patients with bioprosthetic aortic stenosis or regurgitation who are deemed high risk for repeat open heart surgery. Although the procedure is successful with proper preprocedural assessment, instances of left main (LM) coronary artery ostium obstruction have been doc...

Emergent Chimney Stent to Treat Left Main Occlusion Following Valve-In-Valve Transfemoral Aortic Implantation Chimney Stent Following Valve-In-Valve TAVI

Implantation of transcatheter valves inside degenerated surgical bioprosthesis is nowadays a very good alternative to redo a new cardiac surgery especially in high risk patients. Although procedural success is achieved in most of the patients, these procedures are associated with few potential risks such as coronary occlusion. It is very important to perform an exhaustive study prior to the val...

Case Report : Post transcatheter aortic valve replacement shock : Value of multimodal imaging

Complications resulting from the delayed clinical presentation of a left main coronary artery obstruction can be catastrophic. This case report presents a 73-year-old woman with severe aortic stenosis who underwent transcatheter aortic valve replacement with a core valve who, approximately 20 minutes after heparin reversal with protamine, became hypotensive and was unresponsive to vasopressor a...

Intravascular ultrasound observation of an obstruction of the left main coronary artery caused by displaced leaflet calcification and hematoma after transcatheter aortic valve implantation.

Coronary Obstruction Following Transcatheter Aortic Valve Implantation

BACKGROUND Transcatheter aortic valve implantation (TAVI) was established as an important alternative for high-risk patients with severe aortic stenosis. However, there are few data in the literature regarding coronary obstruction, that although rare, is a potentially fatal complication. OBJECTIVE Evaluate this complication in Brazil. METHODS We evaluated all patients presenting coronary ob...
