Insights
Coronary artery perforation during percutaneous transluminal coronary angioplasty (PTCA) is rare. This case details a PTCA-induced coronary rupture that created an abnormal connection to the right ventricular outflow tract.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiovascular Surgery
Background:
- Coronary artery perforation is a rare but serious complication of percutaneous transluminal coronary angioplasty (PTCA).
- Most perforations result in communication with the pericardial space, potentially leading to cardiac tamponade.
- Alternative drainage pathways, such as fistulization into cardiac chambers, are exceptionally uncommon.
Observation:
- A patient undergoing PTCA experienced an unexpected coronary artery rupture.
- The rupture created an abnormal connection (fistula) between the coronary artery and the right ventricular outflow tract.
- This communication pathway is distinct from typical pericardial space involvement.
Findings:
- The case demonstrates a unique sequela of PTCA-induced coronary perforation.
- Coronary artery-to-right ventricular outflow tract fistula represents a rare but significant iatrogenic injury.
- Diagnostic imaging confirmed the anatomical details of the fistula.
Implications:
- This case highlights the importance of considering unusual presentations of coronary perforation.
- Understanding such rare fistulas is vital for guiding interventional and surgical management strategies.
- Further investigation into the mechanisms and optimal treatment of these rare fistulas is warranted.
Abstract:
Coronary perforation caused by percutaneous transluminal coronary angioplasty (PTCA) occurs rarely and most often leads to communication to the pericardial space. We report a case where PTCA caused a coronary artery rupture and fistulization to the right ventricular outflow tract.
