ABSTRACT
A 67 year-old normotensive woman had a syncope followed by shock and remained anuric after hemodynamic stabilization. Paraplegia and paresis of the right upper limb, as well as signs of ischemia of the distal lower limbs were noted. The possibility of acute aortic dissection was raised and confirmed by computed tomography. The paraplegia was attributed to an ischemic infarction of the spinal cord. The patient died on the fourth hospital day due to a pericardial temponade. This rare and not well recognized complication of aortic dissection is briefly reviewed.

A 65-year-old woman developed severe coronary insufficiency associated with papillary muscle dysfunction. She was submitted to cineangiocoronarography which ruled out obstructive coronary disease. Coronarography revealed a communication between the coronary arteries and the left ventricle, but a coronary arterial fistula was not seen. The possibility of this uncommon form of coronary drainage to the left ventricle, named silent fistula, being the cause of myocardial ischemia related to the coronary steal phenomenon is discussed.

A case is reported of the variant form of Prinzmetal angina, occurring two months after effort angina, in which the electrocardiogram revealed a Q wave in V2 in addition to ST segment elevation in precordial leads all of which disappeared in a few minutes. Several hours later, the ECG changes were suggestive of antero-septal infarction. However, four days later an R wave was present in lead V2, and 12 days after the acute episode, the tracing became entirely normal. Cinecoronary angiography revealed severe obstruction of the anterior descending artery, and a moderate obstruction of the left circumflex artery. The possibilities of spasm and/or coronary thrombosis, of spontaneous recanalization and of reperfusion due to thrombolysis are discussed, in addition to interpreting the abnormal Q waves as presumably due to severe myocardial ischemia resulting from acute coronary insufficiency. The present case exemplifies the concept that the syndromes of acute coronary heart disease cannot always be precisely differentiated, since they often overlap and are difficult to identify.
