Balanced steady-state free precession MR images are obtained in standard cardiac planes. Long-axis and four-chamber view (A), long-axis and four-chamber late gadolinium-enhanced MR image (B), long-axis and two-chamber view (C), and short-axis and two-chamber view (D).

Furthermore, computed tomography coronary angiography (CTCA) revealed diffuse wall thickening in the left main (LM) and left anterior descending (LAD) coronary arteries and moderate stenosis in the proximal segment of the LAD (Supplementary Figure 1). The poor clinical response promoted further imaging (Figure 1).
Coronary angiography (CAG) (A,B) revealed woven coronary artery (WCA).

CAG for further investigation, which revealed that the LM and proximal LAD looked woven:they split into multiple slender arteries that intertwined and twisted along the axis of the coronary artery:and were fully occluded except for the D1 branch (Figure 2). CAG visualized the vascular morphology, and WCA was preliminarily diagnosed.
