“…The positive aspect of this proliferation is that the site of the former plaque is solidly sealed by a fibrous cap and will—as opposed to a normal coronary plaque—very seldom rupture and nearly never produce a thrombotic occlusion (3). Furthermore, it was shown that when patency is obtained six months after successful angioplasty, a 95% long‐term patency rate with regression of the residual stenosis can be expected (4), and the further prognosis of the patient is essentially dependent on risk factors for coronary mortality in general (5). This led to the notion of plaque sealing (6).…”

Purpose: To assess the diagnostic value of three-dimensional coronary magnetic resonance (MR) angiography with fat saturation and navigator echo in the setting of restenosis after percutaneous transluminal coronary angioplasty (PTCA). Materials and Methods:Thirty consecutive patients who had PTCA and were referred for elective coronary reangiography underwent MR imaging and coronary angiography. The pulse sequence was a cardiac triggered, single-slab, three-dimensional, gradient-echo sequence, employing a spin-echo navigator echo measurement to track the variation of the diaphragm during the scan. The following segments of the coronary arteries were included in this prospective study: left main coronary artery, proximal and middle left anterior descending, proximal and middle left circumflex, proximal and middle right coronary artery, and intermediate branch, if present. The quality of the MR images was graded from 0 to 5. Results:In total, 221 coronary artery segments could be identified. Mean image quality was 3.3. Overall accuracy for segments with an image quality of grade 2 or more was 90%. To achieve a positive predictive value Ͼ70% for a significant stenosis/restenosis, only segments with quality Ն3 could be assessed, whereas an acceptable negative predictive value could be achieved for nearly all segments. Conclusion:Our preliminary data suggest that MR coronary angiography may be most helpful as a screening test in selected patients to exclude clinically relevant stenoses or to assess restenoses after PTCA or in patients in whose coronary angiography is relatively contraindicated.
