A rare case of acute right coronary artery occlusion occurred during aortic valve replacement surgery. Prompt surgical intervention via coronary artery bypass resolved the complication, highlighting the need for surgeon awareness.
Area of Science:
- Cardiology
- Cardiac Surgery
- Vascular Surgery
Background:
- Aortic valve stenosis is a critical condition requiring surgical intervention.
- Cardiac valve surgery carries inherent risks, including potential coronary artery complications.
- Understanding rare complications is crucial for improving patient outcomes.
Observation:
- An 85-year-old female presented with heart failure due to severe aortic valve stenosis.
- During aortic valve replacement, intraoperative right ventricular failure was observed.
- Postoperative investigations revealed acute occlusion of the proximal right coronary artery.
Findings:
- The acute coronary artery occlusion led to absent distal flow to the right ventricle.
- An emergent right coronary artery bypass procedure was successfully performed.
- The patient experienced resolution of right ventricular failure and made an excellent recovery.
Implications:
- This case highlights a rare but serious complication of cardiac valve surgery.
- Early recognition and rapid intervention for acute coronary artery occlusion are vital.
- Awareness of this potential complication can improve surgical management and patient safety.
