Congenitally corrected transposition of the great arteries and exercise-induced ventricular tachycardia

Congenitally corrected transposition of the great arteries (CCTGA) is an uncommon condition. Few patients survive past 50 years of age, because of associated congenital defects, systemic (morphological right) ventricular dysfunction, atrioventricular valvular insufficiency or complete heart block. A unique case is presented of exercise-induced ventricular tachycardia, which led to the diagnosis of CCTGA, without atrioventricular block or other cardiac anomalies.

Spontaneous coronary artery dissection in young women

Spontaneous dissection of the coronary arteries is quite rare. It is usually a catastrophic event with fatal outcome. We report two interesting cases of spontaneous dissection whose presentations exemplify the variable course the disorder may take. The first is the only report to our knowledge associated with aerobic exercise; the second is the only reported attempt at treatment with intracoronary thrombolysis.
