Abstract

Transseptal puncture (TSP) is commonly conducted under the guidance of fluoroscopy and/or intracardiac echocardiography (ICE) at the fossa ovalis (FO) to gain percutaneous access to the left atrium for intracardiac procedures. Issues with traditional TSP include: additional vascular access through a sheath, and fluoroscopy exposes patients to ionizing radiation. TSP, if not done appropriately can result in serious complications. We studied the feasibility of optical coherence tomography (OCT) guidance of TSP with ex vivo and in vivo experiments. Results show that OCT can provide detailed structure information to identify FO allowing for safe TSP.
