Abstract:
UNLABELLEDTo evaluate the detection rate of myocardial bridging by 64-slice spiral CT coronary angiography.
METHODSThe data of 3011 patients with suspected coronary artery disease undergoing 64-slice spiral CT coronary angiography were collected and analyzed retrospectively.
RESULTSA total of 174 cases (5.8%) with myocardial bridging were detected by 64-slice spiral CT coronary angiography, among which 168 (96.6%) had single foci of involvement and 6 (3.4%) had were multiple foci. Involvement of the left anterior descending coronary artery (LAD) was detected in 167 out of the 174 cases (96.0%). The length of the myocardial bridge varied between 5 and 120 mm (mean of 30.5 mm), and the depth of the tunneled artery ranged between 1.3 and 2.8 mm (mean 2.3 mm). Seventy-nine of the cases (45.4%) had uncomplicated myocardial bridging and 95 (54.6%) had myocardial bridging complicated by coronary atherosclerosis.
CONCLUSIONMulti-slice spiral CT coronary angiography is a reliable and noninvasive modality for diagnosis of myocardial bridging to allow direct measurement of the length and depth of the myocardial bridge and detection of concurrent coronary and cardiac lesions.
