Percutaneous transluminal balloon angioplasty of the aorta in patients with aortitis

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Vascular Surgery

Background:

• Aortitis can lead to severe aortic stenosis, causing significant hemodynamic compromise.
• Traditional surgical repair of aortic stenosis in aortitis presents challenges.
• Minimally invasive endovascular techniques offer a potential alternative for managing aortic stenosis.

Purpose of the Study:

• To evaluate the efficacy and safety of percutaneous transluminal balloon angioplasty (PTBA) for treating aortic stenosis in patients with aortitis.
• To assess the immediate and short-term hemodynamic changes following PTBA.
• To determine the symptomatic improvement and complication rates associated with PTBA in this patient cohort.

Main Methods:

• Four patients diagnosed with aortitis and symptomatic aortic stenosis underwent PTBA.
• Angiographic assessment and measurement of peak systolic gradient across stenotic lesions were performed before and immediately after dilatation.
• Repeat angiography and gradient measurements were conducted at a 2-month follow-up for three patients.

Main Results:

• Successful dilatation was achieved in all four patients.
• The peak systolic gradient across aortic constrictions decreased significantly from 82.5 +/- 35.7 mm Hg to 37.5 +/- 18.5 mm Hg post-procedure.
• At 2 months, repeat angiography showed a further reduction in the gradient to 13.8 +/- 9.5 mm Hg in three patients.
• No procedural or post-procedural complications were observed.
• All patients experienced remarkable symptomatic relief during follow-up.

Conclusions:

• Percutaneous transluminal balloon angioplasty is a safe and effective treatment for aortic stenosis in patients with aortitis.
• PTBA leads to significant and sustained reduction in aortic pressure gradients.
• The procedure offers substantial symptomatic improvement with a favorable safety profile in this challenging patient group.
