Tumors of the heart. Experiences at the Giessen University Clinic

Of 54 cardiac tumors operated upon in our clinic, 42 were classified as benign and only 12 as malignant. The major part of the benign tumors were myxoma, mainly located in the left atrium. While smaller tumors could be treated by local resections, extensive resections were necessary in 14 patients with greater tumors followed by reconstructions of the pulmonary and caval vein, mitral and tricuspid valve, and major parts of the right and left ventricular wall. In one patient with a huge benign myxoma, tumor exposition and total resection could only be achieved by an autotransplantation of the heart. While mortality after surgical therapy of benign tumors was only 1.4% (1/42) within a mean follow-up time of 48 months, the prognosis of malignant tumors is still fatal with a mortality of 50% (6/12) within a mean follow-up time of 24 months, despite additional chemotherapy or radiation.
