Spontaneous dissection of coronary arteries.

Spontaneous dissection of coronary arteries is an uncommon entity with varied presentation. It is commoner in young patients, specially females. We present three cases encountered by us in recent past. There were two males and the only female was in her post-partum period. All the three had diverse lines of management based on the angiographic picture, clinical background and myocardium at risk.

Apical hypertrophic cardiomyopathy in association with Takayasu's arteritis.

We describe an interesting case of a patient who had Takayasu's arteritis and apical hypertrophic cardiomyopathy. Electrocardiogram, and transthoracic and transesophageal echocardiograms showed classical features of apical hypertrophic cardiomyopathy which is particularly uncommon outside Japan. To the best of our knowledge, the presence of apical hypertrophic cardiomyopathy in patients with Takayasu's arteritis has not been reported till date.
