Acromegaly is characterized by a hypersecretion of growth hormone and is frequently associated with valvular abnormality and arrhythmia. The increased morbidity and mortality is primarily caused by stroke and cardiovascular disease. Therefore, valve reconstruction and sinus rhythm recovery will be particularly beneficial. We report herein the successful surgical treatment of two patients with combined valvular insufficiency and chronic atrial fibrillation in the setting of acromegaly.
