CONCLUSION
In conclusion, despite the low incidence rate of iatrogenic damage to the LCX caused by the excision and removal of the valve in MVR surgery, the complication can prove complex and life-threatening. The prevention of such a complication is of utmost importance and requires CA on all patients undergoing valve surgery with a view to verify the location of the LCX. (12) In patients without preoperative preliminary angiography that present with symptoms such as ventricular tachycardia, ECG changes, or elevated cardiac biomarkers, we recommend that postoperative CA be performed forthwith to detect any possible injury to the LCX.
