Key result
Electrophysiological study and careful mapping are essential in localizing the site of origin and appropriate treatment for late atrial tachycardia in double lung transplant recipients.
Why the study?
Atrial arrhythmia after double lung transplant is common, but late atrial fibrillation is rarely reported due to electrical block at the donor pulmonary vein and recipient left atrium anastomosis.
Case Report (n=1)
Late atrial tachycardia can originate from the donor pulmonary vein in double lung transplant recipients, requiring careful electrophysiological mapping for appropriate treatment.
Answers are grounded in this paper and cite their sources.
Alerts electrophysiologists to possible late reentry across lung transplant anastomoses; hypothesis-generating for bridging myocardium mechanisms pending larger studies.

Atrial fibrillation is rarely encountered in double lung transplants but is rarely reported in late cases owing to creation of electrical block along the anastomosis between the donor pulmonary vein and recipient left atrium.•Presence of the heterogeneous scar in these patients may allow for micro- and macroreentrant atrial arrhythmia, even relatively late. Conduction across anastomotic lines may be explained through bridging myocardium.•Electrophysiological study and careful mapping is essential in localizing the site of origin and appropriate treatment.

Sanam et al. (2015) conducted a case report in Late atrial tachycardia after double lung transplant (n=1). Electrophysiological study and mapping was evaluated. Electrophysiological study and careful mapping are essential in localizing the site of origin and appropriate treatment for late atrial tachycardia in double lung transplant recipients.
