Insights
A rare left coronary artery fistula was diagnosed in a patient with worsening angina. Percutaneous coronary intervention with coil embolization successfully treated the condition.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Congenital Heart Disease
Background:
- A 62-year-old male presented with progressive stable angina and an acute unstable episode.
- Diagnostic coronary angiography was performed due to worsening symptoms.
Observation:
- Investigations included physical examination, electrocardiography, myocardial perfusion scan, coronary angiography, and cardiac CT.
- Coronary angiography revealed a fistula originating from the left coronary main stem terminating in the pulmonary artery.
Findings:
- The diagnosis was a left coronary main stem to pulmonary artery fistula.
- Management involved percutaneous coronary intervention (PCI) with successful coil embolization of the fistula.
Implications:
- This case highlights the importance of considering coronary artery fistulas in patients with atypical angina.
- Percutaneous closure offers a minimally invasive treatment option for coronary artery fistulas.
- Successful management can alleviate symptoms and prevent complications such as heart failure or myocardial infarction.
Background:
A 62-year old man with progressive deterioration of stable angina presented with an unstable episode and was referred for diagnostic coronary angiography.
Investigations:
Physical examination, electrocardiography, myocardial perfusion scan, coronary angiography, cardiac CT.
Diagnosis:
Left coronary main stem to pulmonary artery fistula.
Management:
Coronary angiography, percutaneous coronary intervention, coil embolisation.
