Abstract

AbstractBackgroundDifferent procedural strategies have been published targeting to facilitate transcatheter left atrial appendage closure (LAAc). We demonstrate feasibility of a procedural set-up allowing single-operator LAAc in a selected patient.Case summaryA 87-year-old male with persistent Afib (CHA2DS2VASc, five; HASBLED, three) was referred to our hospital for LAAc. Pre-procedural planning and device sizing with three-dimensional transesophageal echocardiography (3DTEE) confirmed a non-complex anatomy of the essential anatomical structures predicting suitability for LAAc. Therefore, the procedure was performed with a simplified single-operator interventional approach. Intraprocedural TEE guidance, device preparation, and LAAc were accomplished by the interventionalist himself. For procedural guidance, the TEE probe was arranged and handled in a technique comparable to the use of intracardiac echocardiography (ICE). Procedure time (skin-to-skin) was 21 min, left atrial access time 9 min, and fluoroscopy time was 4:28 min without the use of contrast dye. The patient was discharged the following day in good medical conditions.DiscussionTo the best of our knowledge, this is the first report on successful single-operator LAAc in a selected patient. The intervention, pre-procedural screening, and intraprocedural 3D TEE were performed by one single experienced interventionalist. This simplified technique is based on a standardized pre-procedural imaging-protocol with 3D echocardiography. According to our experience, this streamlined approach is a valuable option in non-complex LAAc cases. In the growing field of structural cardiac interventions, this approach might be an interesting option for centres with limited personal and technical resources.
