Traumatic coronary arteriovenous fistula communicating the left main coronary artery to pulmonary artery, associated with pulmonary valvular insufficiency and endocarditis: case report.

The authors present a case of a seventeen-year-old white male who suffered from a knife chest wound and secondarily developed a traumatic coronary arteriovenous fistula communicating the left main coronary artery to the pulmonary artery, associated with pulmonary valvular insufficiency and endocarditis.

Acute myocardial infarction with normal coronary arteries in a patient with dermatomyositis. Case report.

The authors present a forty-year-old man, with a history of dermatomyositis for the past twelve years, managed intermittently with prednisone. During an exacerbation of his illness he developed an acute anterior wall myocardial infarction with normal coronary arteries. A literature review indicates this represents a rare association.

Cholera and Myocarditis A Case Report

The authors describe the case of a fifty-nine-year-old white man, previously in good health, who initiated his present illness with acute episode of enterocolitis characterized by mild fever and, in the next eight hours, twenty-four episodes of watery diarrhea, nausea and vomiting, as well as generalized sweating and severe weakness secondary to hypovolemia and electrolyte disorder. These complications were corrected in seventy- two hours in the intensive care unit. Two days later, when the patient was stable hemo- dynamically, under cardiac monitoring and with normal laboratory studies including serum electrolytes, he developed electrocardiographic changes characterized by trifasci cular block (prolonged P-R interval, complete right bundle branch block [CRBBB] and left posterior hemiblock [LPH]) with a cardiac rate of thirty beats per minute, for which a temporary pacemaker was inserted. Endomyocardial biopsy showed histopathologic signs of myocarditis and the immunologic study of the cardiac tissue revealed positive poly merize chain reaction (PCR+) with the presence of antitoxine choleric antibodies (AcTCA). After three weeks, the same conduction disturbances remained, for which a permanent pacemaker was inserted. On top of intravenous fluid replacement and elec trolyte supplements, the patient was managed with tetracycline 2 g a day for one week and sulfamethoxazole-trimethoprim 800/160 mg a day for two weeks. The purpose of this study is to present a rare and very well-documented myocarditis by cholera in a patient with enteric disease, in whom several cardiac complications occurred.
