Key result
Transaortic patch angioplasty using the right internal thoracic artery yielded good angiographic results at 6 months in all 3 patients with nonatherosclerotic left main coronary artery stenosis.
Why the study?
Does transaortic patch angioplasty using the right internal thoracic artery provide good angiographic results in patients with nonatherosclerotic isolated left main coronary artery stenosis?
Case Report (n=3)
Does transaortic patch angioplasty using the right internal thoracic artery provide good angiographic results in patients with nonatherosclerotic isolated left main coronary artery stenosis?
Transaortic patch angioplasty using the right internal thoracic artery is a feasible technique for enlarging the left coronary ostium in patients with nonatherosclerotic stenosis without heavy calcification.
May support right ITA patch for select nonatherosclerotic LM stenosis; leaves open durability and generalizability pending larger prospective data.
Three female patients underwent operations for nonatherosclerotic isolated left main coronary artery stenosis. Transaortic patch angioplasty was performed via an anterior approach using the most proximal segment of the right internal thoracic artery as patch material. Six months after surgery coronary angiography revealed good results in all three cases. The internal thoracic artery can be used to enlarge the left coronary ostium safely, if heavy calcification is not present.

Nagy et al. (2001) conducted a case report in Nonatherosclerotic isolated left main coronary artery stenosis (n=3). Transaortic patch angioplasty using the right internal thoracic artery was evaluated on Angiographic results at 6 months. Transaortic patch angioplasty using the right internal thoracic artery yielded good angiographic results at 6 months in all 3 patients with nonatherosclerotic left main coronary artery stenosis.
