Damage to the circumflex coronary artery during mitral valve repair with sliding leaflet technique
1Department of Cardiothoracic Surgery, St. Antonius Hospital, Nieuwegein, The Netherlands.
Insights
Mitral valve repair can injure the circumflex coronary artery, particularly in patients with specific coronary anatomy. Preoperative assessment of coronary anatomy is crucial for preventing this complication during valve reconstruction.
Area of Science:
- Cardiovascular Surgery
- Cardiac Anatomy
- Interventional Cardiology
Background:
- Mitral valve repair is a common procedure for posterior mitral leaflet prolapse.
- Coronary artery disease (CAD) often coexists with mitral valve disease.
- Carpentier's technique is a widely used method for mitral valve reconstruction.
Observation:
- A case of circumflex coronary artery damage during mitral valve repair using the sliding leaflet technique is presented.
- The patient had posterior mitral leaflet prolapse and concomitant coronary artery disease.
- The procedure involved mitral valve reconstruction and coronary artery bypass grafting.
Findings:
- Mitral valve reconstruction, especially with the sliding leaflet technique, carries a risk of circumflex coronary artery injury.
- This risk is heightened in patients with left coronary dominance or codominance.
- Intraoperative transesophageal echocardiography is essential for evaluating mitral valvuloplasty outcomes.
Implications:
- Preoperative knowledge of coronary artery anatomy is vital for surgical planning and risk mitigation.
- Awareness of potential circumflex coronary artery injury is necessary during mitral valve reconstruction.
- Routine use of intraoperative transesophageal echocardiography aids in assessing the success of mitral valve repair and preventing complications.
Abstract:
We report a case of damage to the circumflex coronary artery during mitral valve repair using sliding leaflet technique in a patient with a posterior mitral leaflet prolapse and coronary artery disease who underwent mitral valve reconstruction using Carpentier's technique and coronary artery bypass grafting. This case underscores the risk of circumflex coronary artery injury during mitral valve reconstruction, especially in patients with left coronary dominance or codominance, and therefore emphasizes the importance of knowing the coronary artery anatomy preoperatively. The use of intraoperative transesophageal echocardiography is mandatory for the evaluation of mitral valvuloplasty.
