Primary Cardiac Lymphoma David A. Margolin, MD, Vladimir Fabian, MD, Uri Mintz, MD, and M a r k J. Botham, MD Departments of Surgery and Internal Medicine, Case Western Reserve University School of Medicine and Mt. Sinai Medical Center, Cleveland, Ohio A case of primary cardiac non-Hodgkin's B cell lymphoma is described in a patient presenting with obstructive right heart failure. Unlike the majority of cases, in this case the tumor was diagnosed ante mortem. The patient's history combined with the aggressive use of noninvasive echocardiography are helpful in diagnosing this rare lesion. (Ann Thorac Surg 1996;61:1000-1)

15.0 m m Hg. An inferior vena cavogram confirmed the presence of a mass p r o l a p s i n g into the inferior vena cava with extension inferiorly below the level of the hepatic veins (Fig 1). Cardiac catheterization was performed, revealing n o r m a l coronary a n a t o m y with the exception of collateral vessels that were perfusing the t u m o r from the right coronary artery. I m m e d i a t e l y after catheterization, significant a b d o m i nal pain developed, and the patient was found by radiographic evaluation to have i n t r a a b d o m i n a l free air. Emergently the patient was taken to the operating room, w h e r e he was f o u n d to have an anterior d u o d e n a l perforation. This was r e p a i r e d by G r a h a m plication. The patient b e c a m e p r o f o u n d l y hypotensive during the procedure, with a rapidly falling systolic b l o o d pressure that was u n r e s p o n s i v e to both volume and inotropic support. At sternotomy, the heart a p p e a r e d extremely cyanotic with m a r k e d l y d i m i n i s h e d contractility. The right atrium was massively dilated with extensive t u m o r involvement. The patient was placed on b y p a s s using a r i g h t - a n g l e d venous cannula placed in the superior vena cava and a second venous cannula t h r e a d e d to the retrohepatic inferior vena cava from the right femoral vein. U n d e r 28 m i n u t e s of h y p o t h e r m i c circulatory arrest the right atrium was o p e n e d and a t u m o r m e a s u r i n g 7 × 6 × 4.5 cm was f o u n d to originate from the right atrial free wall with extension through the tricuspid valve a n d into the inferior vena cava. The t u m o r with the attached right atrial wall a n d involved inferior vena cava was excised a n d reconstructed with a bovine pericardial patch to achieve a d e q u a t e surgical margins.

Comment Cardiac involvement in m a l i g n a n t l y m p h o m a s is relatively common, with 20% of patients showing cardiac involvement at the time of death [8]. Primary cardiac l y m p h o m a s in n o n i m m u n o c o m p r o m i s e d individuals are exceedingly rare. Before 1987 there were only 20 r e p o r t e d cases of p r i m a r y cardiac l y m p h o m a s in the Englishlanguage literature. Since 1987 there has b e e n a significant increase in the presence of this lesion associated with i m m u n o s u p p r e s s i o n , both in individuals iatrogenically i m m u n o s u p p r e s s e d for solid organ transplantation and in patients positive for h u m a n immunodeficiency virus or patients with acquired immunodeficiency synd r o m e [4-7]. A l t h o u g h all histologic types of l y m p h o m a involve the heart, those of the diffuse large cell or immunoblastic B cell subtype p r e d o m i n a t e . Burkitt's l y m p h o m a of the heart has b e e n r e p o r t e d on only two occasions. Most patients with a p r i m a r y cardiac l y m p h o m a have a clinical course acute in onset with a r a p i d demise. Early diagnosis m a y best be m a d e by echocardiography. Transesophageal e c h o c a r d i o g r a p h y allows for architectural delineation of (1) single or multiple c h a m b e r involvement, (2) the focal or diffuse nature of the disease, a n d (3) the n e e d for or feasibility of surgical resection. C o m b i n e d c h e m o t h e r a p y a n d radiation t h e r a p y m a y be a p p r o p r i a t e in early stages. Obstructive s y m p t o m s or congestive heart failure often suggest mechanical inflow/ outflow compromise. Surgical exploration is m a r k e d l y a i d e d by h y p o t h e r m i c circulatory arrest, which allows for a bloodless field to examine the extent of t u m o r involvem e n t in the vena cava. Resection a n d reconstruction, if possible, m a y then be undertaken, assuring a tumor-free margin.

We present a case of primary cardiac lymphoma in a patient with dyspnea and hypoxemia. Transesophageal echocardiography revealed a large right atrial mass and an atrial septal aneurysm with right-to-left shunting through a patent foramen ovale. The patient underwent resection and atrial reconstruction. Pathology was a B cell lymphoma with diffuse large cell histology. There was no evidence of extracardiac involvement, and the patient is well 3 months postoperatively with a normal transthoracic echocardiogram.

rimary cardiac tumors, defined as t u m o r s involving only the heart or pericardium, are rare malignancies with a r e p o r t e d incidence 0.0017% to 0.28% [1, 2]. Of p r i m a r y cardiac tumors, p r i m a r y cardiac l y m p h o m a is extremely rare, with an incidence of 1.3% [1]. Primary cardiac l y m p h o m a m a y p r e s e n t as congestive heart failure, pericardial effusion, arrhythmias, or superior vena cava s y n d r o m e [3, 4]. The majority of patients die within weeks after diagnosis or are d i a g n o s e d at autopsy. This case of p r i m a r y cardiac l y m p h o m a is u n u s u a l in that it was h e r a l d e d b y an acute presentation of d y s p n e a a n d h y p o x e m i a from shunting through a p a t e n t foramen ovale.
