Abstract
Autopsy studies have associated congenital coronary anomalies with the risk of sudden cardiac death. However, not all patients with anomalous coronary arteries die suddenly. A means of assessing the potential for ischaemia and thus predicting the risk of sudden death in these patients may be necessary for directing treatment. We present the case of a patient with an anomalous right coronary artery originating from the aortic wall above the left sinus of Valsalva, with an anterior inter-arterial course. The haemodynamic significance of this anomaly was assessed using intracoronary pressure-wire measurements at rest and during dobutamine stress. This technique could be a valid means for assessing stress-induced ischaemia and, therefore, by inference, the risk of sudden cardiac death in these patients.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
