Myocardial bridging and hypertrophic cardiomyopathy: relief of ischemia by surgery.

We describe a case of myocardial bridging of the anterior descending coronary artery associated with a non-obstructive hypertrophic cardiomyopathy which was corrected by surgery because of a poor response to standard drug therapy. The clinical significance of the association is discussed. The possibility of repair by surgery should be considered when an area of ischemia supplied by the affected vessel is detected and previous medical treatment has been ineffective.
