ATRESIA OF THE LEFT MAIN CORONARY-ARTERY - A CASE IN A MARATHON RUNNER - LITERATURE-REVIEW

The authors report the case of a very rare coronary malformation : atr esia of the left main coronary artery. This anomaly was discovered in a marathon runner who presented effort angina with a positive exercise stress test. At coronary angiography, it was not possible to catheter ise the left coronary artery and only a minuscle dimple could be visua lised. Selective right coronary catheterisation showed a very large ri ght coronary artery with retrograde injection of the whole of the left coronary network, as far as the left main stem. The authors did not s uggest revascularisation because of the good functional tolerance of t his malformation.
