Key result
Transesophageal echocardiography successfully demonstrated widely opened left main coronary arteries with good flow in 8 patients, all of whom were alive and free of ischemic events at 8 months to 7 years.
Why the study?
Does transesophageal echocardiography (TEE) effectively evaluate left main anatomy and flow following surgical left main coronary artery patch angioplasty in patients with isolated ostial left main stenosis?

Does transesophageal echocardiography (TEE) effectively evaluate left main anatomy and flow following surgical left main coronary artery patch angioplasty in patients with isolated ostial left main stenosis?
TEE is an effective non-invasive imaging modality for the postoperative evaluation and long-term follow-up of surgical left main coronary artery angioplasty.
Supports TEE for post-angioplasty monitoring in small series; leaves open prospective validation before wider use.
OBJECTIVE: Isolated ostial stenosis of the left main coronary artery is a rare but serious condition. The treatment is surgical with two options: coronary artery bypass grafting or surgical angioplasty of the left main coronary artery. Assessing surgical results as well as follow-up were traditionally done by angiography. METHODS: We describe the use of transesophageal echocardiography (TEE) for evaluating and follow the surgical left main coronary artery (LMCA) angioplasty results in eight patients with isolated ostial left main stenosis. RESULTS: All patients were alive and free of ischemic events 8 months to 7 years post-surgery. TEE demonstrated a widely opened left main coronary artery with a good flow. CONCLUSIONS: Surgical angioplasty is an alternative option for treating ostial LMCA stenosis. TEE is an additional excellent non-invasive technique for assessing left main anatomy pre- and postoperatively, as well as being on of the quality control tools for evaluating new surgical techniques.

Sharoni et al. (2003) conducted an observational in Isolated ostial left main stenosis (n=8). Transesophageal echocardiography (TEE) was evaluated on Survival and freedom from ischemic events. Transesophageal echocardiography successfully demonstrated widely opened left main coronary arteries with good flow in 8 patients, all of whom were alive and free of ischemic events at 8 months to 7 years.
