To the Editor:
We read with interest the article by Lauten and coworkers1 regarding the successful resection of a right atrial papillary fibroelastoma (PF). We have additional surgical experience with this infrequent location of the neoplasm.
A 60-year-old man with a history of arterial hypertension and a transient ischemic attack underwent a transthoracic echocardiogram, which demonstrated a mass inside the right atrium (RA). Further cardiologic evaluation including transesophageal echocardiogram and complete cardiac catheterization and coronary arteriography disclosed a tumor in the RA, fenestrated atrial septal defect (ASD), persistent left superior vena cava (LSVC), and severe coronary artery disease with tight stenosis in the proximal left anterior descending coronary artery (LAD) and middle right coronary artery (RCA).The patient underwent surgery on June 6, 1998. A median sternotomy was performed. Under standard cardiopulmonary bypass, with cannulation of the aorta, both venae cavae, and the LSVC, the aorta was crossclamped. Intermittent cold blood cardioplegia was administered and the three venae cavae were snared. A right atriotomy was performed, a 2 x1.5-cm gelatinous tumor attached to the muscular endocardium of the RA was completely removed, an ostium secundum type of ASD was closed with an autologous pericardial patch, and a double coronary bypass graft to the LAD and RCA was carried out. The patient had an uncomplicated surgery and recovery and was discharged home 10 days after the operation. Gross and histologic examination of the mass was typical of PF. At present, 9 years 6 months after the operation, the patient remains asymptomatic. A recent transthoracic echocardiogram showed no intracavitary masses, closure of the interatrial septum, and normal left ventricular function.
PF is an endocardial tumor that represents the second or third most common cardiac neoplasm, accounting for less than 10% of all primary benign heart tumors. It is most frequent in the left side of the heart and generally develops in the heart valves; however, other endocardial heart locations have also been described. Right PF arising from the nontricuspid valve or interatrial septum is extremely uncommon. We only found a few surgically treated patients.1-7 To the best of our knowledge, excision of a free-wall PF in association with closure of an ASD and coronary artery bypass grafting has not been previously reported.
