Analysis of Echocardiographic Markers and Pulse Wave Velocities in a Patient Who Developed New Cardiac Symptoms after Implantation of an Aortic Endograft.

ABSTRACT

Increased arterial stiffness has been related to altered cardiovascular hemodynamics, left ventricular hypertrophy, and a higher risk for cardiac events. Pulse wave velocity (PWV) has been used as a surrogate marker for arterial stiffness. Treatment of abdominal aortic aneurysms (AAAs) involves insertion of a rigid graft or endograft inside the arterial system which has been shown to increase arterial stiffness, but the cardiac implications of these alterations are mostly unknown. We report a case of a patient with a previous AAA surgical repair (>10 years ago) who developed a para-anastomotic pseudoaneurysm which was excluded with implantation of an endoluminal graft. From a cardiac perspective, this patient was asymptomatic and had a normal baseline preoperative evaluation. He had an initially high PWV (17 m/sec). Postprocedurally, the patient developed cardiac symptoms, and he underwent coronary angiography which indicated significant coronary artery disease, and he subsequently underwent bypass grafting. One week after the endovascular repair, the patient presented with an increased PWV at 21 m/sec. Echocardiographic indices were mostly unaltered (ejection fraction, left ventricular mass index, and left atrium volume index) compared with the preoperative evaluation, except for the global longitudinal strain which deteriorated from -25 to -21%. This case provides insight into hemodynamic alterations after implantation of an endograft which may result in deterioration of asymptomatic heart disease.
