Various anomalies of coronary arterial origin have been described. These anatomical variations are discovered either by coronary angiography or at autopsy. We are reporting a case of anomalous origin of the right coronary artery above the left sinus of Valsalva. To our knowledge, this anomaly has not been described before. A technique for selectively catheterizing such an aberrant coronary artery is described.
In two cases of hyperactive carotid sinus with syncope, both patients had a history of syncopal attacks. Carotid sinus massage produced asystole lasting for four seconds with recurrent symptoms. Permanent demand pacemakers were implanted in both patients, causing a relief of symptoms.
