Aortic Aneurysms and Heart Failure

Mechanisms and Risk Factors

Aortic root or ascending aortic aneurysms can cause dilatation of the aortic annulus, leading to aortic valve regurgitation which may result in heart failure, as reported by the American Heart Association 1
Hypertension is a major risk factor for both aneurysm formation and heart failure, present in up to 85% of patients with ruptured aneurysms, according to the European Society of Cardiology 3
Inflammatory diseases affecting the aorta (vasculitis) can weaken the aortic wall, leading to aneurysm formation and subsequent heart failure, as noted by the European Heart Journal 2
Other common risk factors include smoking, hypercholesterolemia, and chronic obstructive pulmonary disease, as identified by the American College of Cardiology 4

Many patients with thoracic aortic aneurysms are asymptomatic until complications develop, as reported by the American Heart Association 4
When heart failure develops due to aortic regurgitation from an aneurysm, symptoms may include dyspnea (NYHA class II-IV), as described by the European Society of Cardiology 5
Surgical intervention is indicated for symptomatic patients with aortic regurgitation (dyspnea, NYHA class II-IV), as recommended by the European Society of Cardiology 5
Aortic root disease with maximal aortic diameter ≥45 mm for Marfan syndrome, ≥50 mm for bicuspid valves, and ≥55 mm for other patients requires surgical intervention, according to the European Society of Cardiology 5

Regular echocardiographic monitoring is essential for patients with aortic aneurysms to detect early signs of aortic regurgitation, as recommended by the American College of Cardiology 1
Decreasing ejection fraction can be detected through regular echocardiographic monitoring, as noted by the European Society of Cardiology 5
