Summary
Directional coronary atherectomy (DCA) caused a rare complication: coronary artery perforation leading to cardiac tamponade. Emergency surgery was required to manage the life-threatening event.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- Directional coronary atherectomy (DCA) is a procedure to treat blocked coronary arteries.
- Unstable angina resulted from a 90% stenosis in the left anterior descending artery (LAD).
Observation:
- Coronary angiography revealed a perforation of the LAD communicating with the pericardial space post-DCA.
- The patient developed cardiac tamponade and cardiogenic shock.
Findings:
- Emergency surgical intervention included ligation of the perforation and coronary artery bypass grafting.
- The patient required immediate surgical management for bleeding and hemodynamic compromise.
Implications:
- This case highlights an extremely rare but severe complication of DCA.
- Prompt surgical intervention is critical for managing coronary artery perforation and subsequent tamponade.
