ABSTRACT: 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.
