Coronary angiographic, echocardiographic, and electrocardiographic studies on a patient with variant angina due to coronary artery spasm.

A 45-year-old Caucasian female patient with a clinical rehistory and ECG's conforming to the syndrome of variant angina as characterized by Prinzmetal is presented. ECG's recorded during spontaneous pain demonstrated ST-segment elevation and symmetrical peaking of the T-waves in the lateral precordial leads and short runs of ventricular tachycardia. Similar ECG changes were recorded during treadmill exercise- and hand-grip exercise-induced chest pain. An echocardiogram recorded during angina induced by hand-grip exercise demonstrated progressive flattening of septal motion. Multiple views of the coronary system by selective coronary cineangiography were normal with the patient at rest. Angina was then induced by hand-grip exercise and a repeat right anterior oblique view of the left coronary system revealed marked spasm of the left anterior descending artery proximal to the first septal perforator.

Radiographic evaluation of patients with schistosomiasis.

Plain films of the abdomen in advanced states of schistosomiasis reveal massive splenomegaly without evidence of splenic calcification. The liver may be enlarged in the early stages but ultimately decreases and becomes small. Ascites is evident in far advanced disease. Chest films are negative in the early stages, but in advanced disease, dilated pulmonary arteries, right ventricular enlargement, and dilatation of the azygous vein may be recognized. Granulomata are seen as multiple small rounded densities scattered throughout both lung fields. The routine barium swallow will reveal unsuspected esophageal varices. Nine patients were studied preoperatively by panhepatic angiography and 14 post-operatively following splenorenal shunt. Thrombosis of the shunt and hepatic encephalopathy were common postoperative complications.

Experimental Closure of Arteriovenous Fistula by Transcatheter Electrocoagulation.

Introduction of a small electric current by way of a catheter-placed electrode can completely occlude experimentally produced arteriovenous fistula. The occlusion appears permanent and without morbidity in experimental animals. This technique might be clinically useful in obliterating an arteriovenous fistula and controlling gastrointestinal hemorrhage.
