Surgical Treatment of Atrial Myxomas: Outstanding Outcome of a Treacherous Tumor.

Background: Primary cardiac tumors are quite rare and mostly benign in nature. Most of the benign heart tumors are myxomas. These might present with a wide range of symptoms from being completely asymptomatic to having life-threatening complications like stroke, heart failure, or even sudden death. This study summarizes our 6-year clinical experience with surgical resection of cardiac tumors at Chittagong Medical College and Hospital, Chattogram, Bangladesh.

Methods: Twenty patients who underwent surgical excision of primary intracardiac myxoma between February 2014 and February 2020 were included in the study. Seventeen (85%) of them were female and 3 (15%) were male. Mean age was 43.4 ± 14.1 years. The tumors were located in the left atrium in 19 patients and in 1 patient it was in the right atrium. The most common attachment site was the interatrial septum. Most of the patients presented with dyspnea. Preoperative diagnosis was established using transthoracic echocardiography with colour Doppler. Surgery for all patients was via median sternotomy.

Results: All 20 patients survived the surgery. Mean tumor dimension was 4.6 ± 3.5 cm in the longest diameter. Solid tumors were detected in 13 patients (65%) whereas papillary myxomas were found in 7 patients (35%). On follow-up of these 20 patients, there was no perioperative death. One patient presented with recurrence 28 months after the surgery.

Conclusions: Although cardiac myxomas carry the risk of serious systemic and cardiac symptoms, prompt surgical excision gives excellent outcome.
