A fatal combination in a young lady: Long QT syndrome and coronary artery anomaly.

Anomalous origin of coronary arteries is also a relatively rare congenital malformation and has been reported as the cause of angina pectoris and arrhythmia. Long QT syndrome (LQTS) is a rare inherited arrythmogenic disease characterized by susceptibility to life-threatening arrhytmias andsudden cardiac death. We present a 36-year-old patient in whom two rare anomalies coexist and treated succesfully with β-blocker therapy.
