Coronary angioplasty of anomalous left anterior descending artery with the left coronary artery originating from the right coronary sinus of Valsalva.

Percutaneous transluminal coronary angioplasty of anomalous coronary arteries presents several technical challenges to interventional cardiologists. Choosing the best guiding catheter and other equipment is crucial to the technical success of the procedure. We performed successful coronary angioplasty of an anomalous left anterior descending artery lesion in a 51-year-old man who had a left coronary artery originating from the right coronary sinus. We review his case, along with this rare anomaly and the technical considerations for successful percutaneous transluminal coronary angioplasty in such a patient.
