Aortic valve replacement in osteogenesis imperfecta--technical and practical considerations for a successful outcome

Area of Science:

• Cardiology
• Vascular Surgery
• Genetics

Background:

• Osteogenesis imperfecta is a rare inherited connective tissue disorder characterized by bone fragility.
• Aortic insufficiency is an uncommon but serious complication associated with this condition.
• Surgical interventions in patients with Osteogenesis imperfecta carry significant risks due to bleeding tendencies and fragile tissues.

Observation:

• A 42-year-old male with isolated aortic incompetence, a rare manifestation of Osteogenesis imperfecta, was evaluated for surgical intervention.
• The patient presented with severe aortic valve dysfunction requiring valve replacement.
• Preoperative assessment focused on managing potential bleeding complications inherent to Osteogenesis imperfecta.

Findings:

• The patient successfully underwent aortic valve replacement (AVR) using a mechanical prosthesis.
• The postoperative course was uneventful, with no major bleeding complications.
• The patient was discharged on postoperative day 7 and remains well at 6-month follow-up.

Implications:

• Meticulous surgical technique and a proactive perioperative management strategy are crucial for successful outcomes in Osteogenesis imperfecta patients undergoing cardiac surgery.
• This case underscores the feasibility of AVR in selected patients with Osteogenesis imperfecta, challenging previous notions of high surgical risk.
• Further research into optimizing surgical approaches and anesthetic management for this patient population is warranted.
