How serious is a 2 cm congenital myocardial bridge? 49-year-old male, with severe sleep apnea. surgery set for open heart surgery july 6 due to risk of sudden death. seeking second opinion at columbia. is it truly that serious?

I assume no symptoms, good stress test. Mortality from these congenital bridges is low. I recommend a second opinion by a cardiothoracic surgeon at a department of cardiothoracic surgery at a university hospital like Columbia. Perhaps dynamic studies can be done to see degree of compression of the artery during systole& diastole which will show how much diminished blood flow. Meds can treat also
