“…987 35 (3.5%) Table 9 DISCUSSION: Iskandrian and others [9][10][11][12][13] in their studies of myocardial bridging mentioned that among patients undergoing coronary angiography, the reported prevalence of myocardial bridging is 1.7 percent (range 0.5 to 16 percent), which is almost always confined to the left anterior descending artery (LAD) where as the present study reveals it as 3.5% only confined to LAD as well. Mookadam et al [14] in coronary angiography of 14, 416 patients reported myocardial bridging in 1.57% of cases.…”

Out of nine hundred and eighty seven (987) coronary angiogram reports, in the present study we analysed the prevalence and distribution of bridging segments. The co-relation of these tunnelled segments with diseased and non-diseased coronary arteries and cardiac dominance were also assessed. Myocardial bridging was exclusively confined to LAD predominantly in the midsegmentG of nondiseased arteries in right dominant circulation. Although bridging provides an atheroprotective milieu, it even harboured atherosclerosis proximal to it. Significantly altering coronary macro and micromechanics it plays a significant role behind genesis of coronary ischemia and its management.

“…Traditionally, the area under the MB has been considered to be spared from atherosclerosis, and the area just proximal to it has been considered to be prone to the development of atherosclerosis along with shear stress considerations. 10,[18][19][20] The high-pressure gradients may increase the local wall tension and stretch and induce endothelial injury and plaque fissuring with subsequent thrombus formation, which is supported by autopsy and clinical studies. 21 In addition, the atherosclerosis process in the segments proximal to ICA is subject to the complex hemodynamics caused by retrograde blood flow from the MB squeezing at systole.…”

Objective-The clinical significance of an intramural course (or bridging) of the coronary artery remains controversial. We investigated the relationship between intramural coronary arteries (ICAs) and coronary stenosis and prognosis of subjects with ICA. Methods and Results-ICA and coronary stenosis were assessed by multidetector computed tomography coronary angiography. ICAs in the left anterior descending artery were studied, which were further classified as superficial (≤2 mm) or deep type (>2 mm). Coronary stenosis was classified as nonstenosis, insignificant stenosis (<50%), and significant stenosis (≥50% Key Words: coronary artery stenosis ◼ intramural coronary artery ◼ major cardiac event ◼ multidetector computed tomography ◼ myocardial bridging

“…Our previous pilot-study provided first observations to assess the association between MB and proximal atherosclerosis, with the relevant bias of inclusion of patients with known CAD and prior myocardial revascularizations [19]. The present study was designed to include only patients with suspected CAD and to assess the MB influence on coronary atherosclerosis distribution and pattern providing a comparison with a clinically similar group of patients without MB by means of CT-CA.…”

“…CT Coronary Angiography (CT-CA) allows the detection of significant coronary artery stenoses and provides a valid alternative to CCA in selected patient populations [6,7]. Recent studies demonstrated that MB may be displayed with 16-and 64-slice CT-CA [8][9][10][11][12][13][14][15][16][17][18] and that proximal atherosclerotic lesions could be associated [19]. In our study, a population of patients who underwent CT-CA according to current clinical indications [6,7] was reviewed for the presence of MB and segmental atherosclerotic pattern.…”

The aim of our study was to evaluate the atherosclerotic pattern of patients with coronary myocardial bridging (MB) by means of CT Coronary Angiography (CT-CA). 254 consecutive patients (166 male, mean age 58.6 ± 10.3) who underwent 64-slice CT-CA according to current clinical indications were reviewed for the presence of MB and concomitant segmental atherosclerotic pattern. Coronary plaques were assessed in all patients enrolled. 73 patients (29%) presented single (90%) or multiple (10%) MB, frequently (93%) localized in the mid-distal left anterior descending artery. The MB segment was always free of atherosclerosis. Segments proximal to the MB presented: no atherosclerotic disease (n = 37), positive remodeling (n = 23), <50% (n = 14), or >50% stenoses (n = 7). Distal segments presented a different atherosclerosis pattern (P < 0.0001): absence of disease (n = 73), no significant lesions (n = 8). No significant differences were found between segments proximal to MB and proximal coronary segments apart from left main trunk. Pattern of atherosclerotic lesions located in segments 6 and 7 significantly differs between patients with MB and patients without MB (P < 0.05). CT-CA is a reliable method to non-invasively demonstrate MB and related atherosclerotic pattern. CT-CA provides new insight regarding atherosclerosis distribution in segments close to MB.
