Right atrial appendage thrombosis after percutaneous left atrial appendage occlusion: a case report

1

Left atrial appendage occlusion (LAAO) is a stroke-prevention strategy for atrial fibrillation patients with contraindications to anticoagulation.
2

A 72-year-old man developed right atrial appendage (RAA) thrombosis one year after LAAO, highlighting risks beyond the left atrium.
3

The patient was treated with rivaroxaban, leading to complete resolution of the RAA thrombus within two weeks.
4

RAA thrombosis can occur post-LAAO, especially in patients with heart failure and enlarged cardiac chambers.
5

Clinicians should monitor for right-sided thrombi in atrial fibrillation patients after LAAO and individualize anticoagulation strategies.
