Coronary artery dissection, combined aortic valve replacement and coronary bypass grafting in osteogenesis imperfecta

Area of Science:

• Cardiology
• Genetics
• Vascular Surgery

Background:

• Osteogenesis imperfecta is a rare inherited connective tissue disorder.
• Cardiovascular manifestations like aortic root dilation are uncommon but serious.
• Patients with osteogenesis imperfecta have elevated risks during cardiac surgery.

Purpose of the Study:

• To report a rare case of coronary artery dissection in an osteogenesis imperfecta patient.
• To highlight the challenges and successful management of a complex cardiovascular event in this patient population.

Main Methods:

• Case report of a patient with osteogenesis imperfecta and severe aortic regurgitation.
• Coronary angiography revealing dissection, followed by stenting.
• Emergency surgical intervention including aortic valve replacement and coronary artery bypass grafting.

Main Results:

• Coronary artery dissection occurred after coronary angiography.
• Initial stenting did not fully seal the dissection.
• Successful emergency combined aortic valve replacement and coronary artery bypass grafting was performed.

Conclusions:

• Coronary artery dissection is a potential complication in osteogenesis imperfecta patients undergoing angiography.
• Multidisciplinary surgical intervention can be life-saving in managing these complex cardiovascular events.
• Careful patient selection and surgical planning are crucial for managing osteogenesis imperfecta patients with cardiovascular disease.
