title: [Simultaneous occurrence and treatment of right atrial myxoma and extensive colonic polyposis causing recurrent intestinal hemorrhages].
abstract: The authors describe the case history of 68 year old man. Right atrial myxoma had been diagnosed two years prior to this present observation, however surgical intervention has been contraindicated due to high operative risk. Later the patient was referred to a cardiological evaluation because of chronic atrial fibrillation before a cataract surgery in a symptom free condition. The right atrial myxoma caused inflow obstruction and tricuspid regurgitation was removed before the eye surgery. In addition, tricuspid valve replacement and revascularization of three coronary arteries has been performed. The patient receiving chronic anticoagulant therapy experienced severe gastrointestinal bleeding the source of which turned out to be a partially malignant colon polyposis. The polyps were successfully removed by coloscopy and intra operative coloscopy. No gastrointestinal bleeding has been observed afterwards in spite of the continued anticoagulation. After review of the literature the authors observed that according to their knowledge the common occurrence of the right atrial myxoma and the colon polyposis had not been described before.
