Dual-Cavity Spontaneous Sinus of Valsalva Pseudoaneurysms: A Diagnostic and Therapeutic Challenge.

ABSTRACT:

Background

Sinus of Valsalva pseudoaneurysms are rare vascular anomalies with potentially life-threatening complications, and their diagnosis is challenging.

Case summary

A 75-year-old man presented with exertional dizziness and dyspnea. Imaging revealed a rare dual-cavity pseudoaneurysm of the right sinus of Valsalva, causing right ventricular outflow tract obstruction and moderate-to-severe aortic regurgitation. Multidetector computed tomography was pivotal for diagnosis and surgical planning. The patient underwent successful repair using the Bentall-de Bono technique, followed by pacemaker implantation owing to complete heart block.

Discussion

This case underscores the diagnostic complexity and clinical impact of spontaneous sinus of Valsalva pseudoaneurysms. The d
