Summary
A chest wall "steal" phenomenon may cause recurrent angina after coronary artery bypass grafting. Embolizing a patent internal mammary artery branch resolved myocardial ischemia and angina symptoms.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Myocardial Ischemia Research
Background:
- Recurrent angina after coronary artery bypass grafting (CABG) is a clinical challenge.
- The "chest wall steal" phenomenon, where blood is diverted from the myocardium to the chest wall via patent internal mammary artery (IMA) grafts, is a debated cause.
- Physiological arguments against the steal phenomenon exist due to differing systolic and diastolic flow patterns in the chest wall and coronary arteries.
