Triple Loop Atrial Flutter Occurring After a Lung Transplant
Takumi Yamada
TL;DR
A rare triple loop atrial flutter was identified after a lung transplant, involving electrical connections between the recipient's heart and donor tissue.
Contribution
The study identifies a novel mechanism of atrial flutter involving donor and recipient tissue connections post-lung transplant.
Findings
Triple loop atrial flutter was mapped using high-density activation.
Electrical connections between the recipient left atrium and donor pulmonary vein cuff contributed to the flutter.
A surgical scar at the mitral isthmus acted as a substrate for the arrhythmia.
Abstract
High‐density activation mapping with a multipolar catheter revealed a triple loop atrial flutter occurring after a lung transplant in which two electrical connections between the recipient left atrium and the donor left pulmonary vein cuff and a surgical scar at the mitral isthmus acted as a substrate.
