Key result
Watchman LAA occlusion is technically feasible and safe after biatrial heart transplantation.
Why the study?
Anatomical changes following biatrial anastomosis in orthotopic heart transplant complicate transesophageal echocardiography imaging and transseptal puncture for LAA occlusion.
Is percutaneous left atrial appendage occlusion using a Watchman device safe and feasible in a patient with a transplanted heart with biatrial anastomosis?

Is percutaneous left atrial appendage occlusion using a Watchman device safe and feasible in a patient with a transplanted heart with biatrial anastomosis?
Demonstrates the feasibility and safety of LAA occlusion using a Watchman device in a patient with a biatrial anastomosis orthotopic heart transplant, detailing modifications for TEE imaging and transseptal puncture.
A percutaneous left atrial appendage (LAA) occlusion using a Watchman device was performed in a patient with prior biatrial anastomosis orthotopic heart transplant (OHT). Due to the anatomical changes following biatrial anastomosis, transesophageal echocardiography (TEE) imaging and transseptal puncture become technically challenging. We describe how the standard LAA views on TEE were obtained for device sizing, and how the transseptal puncture was modified to cross the scarred septum. This case demonstrates that LAA occlusion using a Watchman device in biatrial anastomosis OHT is safe and can successfully be done.

Poulin et al. (2018) conducted a case report in Prior biatrial anastomosis orthotopic heart transplant (n=1). Left atrial appendage occlusion using a Watchman device was evaluated on Procedural safety and feasibility. Left atrial appendage occlusion using a Watchman device in a patient with biatrial anastomosis orthotopic heart transplant is safe and technically feasible despite anatomical challenges.
