Combined Minimally Invasive Transcatheter Approach for Aortic Stenosis and Abdominal Aortic Aneurysm: A Case Report
DOI: 10.36660/abcimg.20260042i
Introduction
An aortic aneurysm is defined as a localized arterial dilation exceeding the normal vessel diameter by more than 50% or the expected diameter of the specific aortic segment by more than 2 standard deviations., The prevalence of abdominal aortic aneurysm (AAA) among individuals aged > 65 years is significantly higher in men.– AAA rupture is associated with high mortality, estimated at 80%-90%, particularly when prehospital deaths are taken into account. The management of this condition has advanced substantially, particularly following the development of vascular endografts with improved safety and flexibility profiles., These technological advances have expanded therapeutic options for patients considered to be at high surgical risk or with anatomical characteristics unfavorable for open surgical repair.–,,
Severe aortic stenosis (AS) is the leading cause of left ventricular (LV) outflow tract obstruction and most commonly manifests clinically as dyspnea, dizziness or syncope, and angina pectoris., Symptomatic severe AS, even when clinical manifestations are mild, requires intervention because, in the absence of valve replacement, it is associated with a poor prognosis, with a mean survival of only 2-3 years and a high risk of sudden cardiac death. In patients with severe calcific AS, surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) are the mainstays of treatment, providing symptom relief and improved survival. The coexistence of severe AS and AAA has been increasingly observed, a phenomenon attributed in part to population aging.
