Surgical transsection of a large congenital right atrial aneurysm restored regular sinus rhythm and normalized cardiac output in a patient with recurrent supraventricular arrhythmia.
Case Report (n=1)
Does surgical transsection of a congenital right atrial aneurysm resolve supraventricular arrhythmias and improve cardiac output?
Surgical resection of a congenital right atrial aneurysm can successfully resolve associated supraventricular arrhythmias and restore normal cardiac output.
A patient is described in whom a large congenital aneurysm or diverticulum of the right atrium caused repeated attacks of supraventricular arrhythmia and a strikingly reduced cardiac output. The aneurysm, which contained a large thrombus, was demonstrated by preoperative angiographic examinations. At the time of operation, regular rhythm returned at the moment the aneurysm was transsected. The patient is asymptomatic after operation, and has maintained sinus rhythm. A normal cardiac index was recorded at postoperative cardiac catheterization.
Morrow et al. (Mon,) conducted a case report in Congenital aneurysm (diverticulum) of the right atrium (n=1). Surgical transsection of the aneurysm was evaluated on Return of regular rhythm and normal cardiac index. Surgical transsection of a large congenital right atrial aneurysm restored regular sinus rhythm and normalized cardiac output in a patient with recurrent supraventricular arrhythmia.
