Limited aneurysmal resection with tricuspid valve ring annuloplasty and RA diathermy MAZE was performed in a 44-year-old man with a giant right atrial appendage aneurysm and atrial tachycardia.
Case Report (n=1)
Surgical resection combined with annuloplasty and a MAZE procedure is a viable treatment approach for intractable atrial tachycardia driven by a giant right atrial appendage aneurysm.
Hypothesis-generating for surgical management of giant right atrial appendage aneurysm with atrial tachycardia; prospective studies needed before adoption.
A 44-year-old man presented with a history of crippling rapid palpitations. On evaluation, his ECGs showing incessant atrial tachycardia with variable AV conduction and LBBB during 1:1 AV conduction. Echocardiography showed right atrial (RA) dilatation with distortion of the tricuspid valve annulus. The RA dilatation was mainly because of giant RA appendage aneurysm; this was subsequently confirmed and delineated by transesophageal echocardiography and MRI. Limited aneurysmal resection with tricuspid valve ring annuloplasty was performed, and RA diathermy MAZE was carried out.

Bachani et al. (2019) conducted a case report in Right atrial appendage aneurysm with intractable atrial tachycardia (n=1). Limited aneurysmal resection with tricuspid valve ring annuloplasty and RA diathermy MAZE was evaluated. Limited aneurysmal resection with tricuspid valve ring annuloplasty and RA diathermy MAZE was performed in a 44-year-old man with a giant right atrial appendage aneurysm and atrial tachycardia.
