ECG of the month. Cardiac failure and stroke in a 43-year-old woman. Coarse atrial fibrillation indicating left atrial enlargement and left ventricular hypertrophy with repolarization abnormality.

A 43-year-old woman with a long history of heavy cigarette smoking was in good health until she developed fatigue, dyspnea on exertion, and paroxysmal nocturnal dyspnea approximately three months before admission to our hospital. Four weeks before admission, she was admitted to another hospital for the sudden onset of a right hemiparesis. She was noted to be in atrial fibrillation, and cardiac catheterization and angiocardiography revealed triple-vessel coronary arterial disease and moderately severe mitral regurgitation.

Ecg of the month. Unusual electrocardiogram 42 years after operation for supravalvular aortic stenosis and 6 years after aortic valve replacement. Sinus rhythm with first degree atrioventricular block.

A 43-year-old man came to the hospital because of increasing dyspnea for two weeks. At age nine months the patient was evaluated for failure to thrive, and a diagnosis of valvular aortic stenosis was made. At operation the aortic stenosis was found to be supravalvular, and the ascending aorta was enlarged with a Teflon patch, the proximal end of which was placed in the noncoronary sinus of Valsalva.

Repair of large, iatrogenic, tracheo-esophageal fistulae.

Closure of large, iatrogenic, tracheo-esophageal fistulae present a formidable technical challenge. Our method of repair is presented, which describes the exposure and subsequent closure that relies on creating a new "membranous" trachea using remnant flaps of the esophageal wall of the fistula.
