David's procedure for pulmonary artery aneurysm

Area of Science:

• Cardiology
• Thoracic Surgery
• Vascular Surgery

Background:

• Pulmonary artery aneurysm (PAA) is a rare condition often presenting late with severe complications.
• Idiopathic pulmonary arterial hypertension (IPAH) can be associated with PAA, leading to complex cardiovascular issues.

Observation:

• A 39-year-old female with IPAH presented with a giant PAA.
• The giant PAA caused severe pulmonary regurgitation (PR) and symptomatic left main coronary artery (LMCA) compression.
• Previous LMCA stenting had failed.

Findings:

• Surgical intervention included a valve-sparing David-like pulmonary trunk reconstruction and coronary artery bypass grafting.
• The patient's condition was successfully managed with this surgical approach.

Implications:

• This case demonstrates the feasibility of the David-like reconstruction technique for managing giant PAAs with severe PR.
• The findings suggest a potential surgical solution for complex PAA cases previously considered high-risk.
• This approach may offer a valve-sparing option in PAA management.
