Summary
A rare paravalvular aortic rupture occurred 5 years post-aortic valve replacement. This complication involved the circumflex coronary artery, leading to angina symptoms.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Complications
- Aortic Valve Replacement
Background:
- Aortic valve replacement (AVR) is a common procedure for aortic valve disease.
- Paravalvular leaks are known complications following AVR.
- Long-term complications of AVR require ongoing surveillance.
Observation:
- A case of paravalvular aortic rupture is presented.
- The rupture occurred 5 years after AVR with a #25 Omniscience tilting disc prosthesis.
- The rupture site was adjacent to the aortic annulus.
Findings:
- The paravalvular rupture extended to involve the circumflex coronary artery.
- This involvement of the coronary artery caused acute angina.
- This represents the first reported instance of such a specific complication post-AVR.
Implications:
- This case highlights a rare but severe complication of aortic valve replacement.
- Coronary artery involvement secondary to paravalvular rupture can lead to myocardial ischemia.
- Increased vigilance and potential diagnostic strategies may be warranted for patients with late paravalvular complications.
