Anomalous origin of the right coronary artery above the left sinus of Valsalva.
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.

Carotid sinus syncope. Report of two cases.
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.
