Аннотация
OBJECTIVE: To describe an anatomy-guided transcatheter edge-to-edge mitral valve repair (M-TEER) strategy using a native secundum atrial septal defect (ASD) as the sole transseptal access route.
KEY STEPS: Preprocedural computed tomography and 3-dimensional transesophageal echocardiography to assess the access route, ASD anatomy, and anticipated guide catheter alignment. Guidewire and steerable guide catheter advancement through the native ASD under real-time 3-dimensional transesophageal echocardiography guidance. Sequential M-TEER device deployment with continuous hemodynamic and oximetric monitoring. Confirmation of mitral regurgitation reduction and planned staged ASD closure.
POTENTIAL PITFALLS: Preprocedural multimodality imaging may help determine procedural feasibility. In patients with decompensated heart failure, staged ASD closure after M-TEER may be preferable.
TAKE-HOME MESSAGES: Preprocedural multimodality imaging may identify patients in whom a native secundum ASD can serve as the sole transseptal access route for M-TEER, avoiding additional septal puncture. In patients with decompensated heart failure, staged ASD closure after successful M-TEER may be preferable.
