摘要

The association between aortic insufficiency and sinus dysfunction is rare. We reported a case of significant chronic degenerative aortic insufficiency associated with sinus dysfunction. This was a 66-year-old patient on follow-up for asymptomatic chronic aortic insufficiency who was referred to us for a preoperative invasive hemodynamic assessment. The indication for surgery was based on the left ventricular dilation criteria. The echocardiography and cardiac catheterization showed a disappearance between the aortic insufficiency and the left ventricular repercussion. Upon discovery of the sinus bradycardia, the patient received a single chamber pacemaker set at a base rate of 70 seconds in AAIR at first and then the patient was measured remotely. At five months, cardiac pacing resulted in a significant reduction in the left ventricular diameter and volume on the echocardiography and magnetic resonance imaging;therefore surgery was postponed.
