Spontaneous coronary artery dissection. (A, B) Coronary angiogram revealed tortuous vessels with evidence of spontaneous coronary artery dissection (SCAD) in multiple coronary arteries including the left anterior descending artery (LAD), posterior descending artery, and posterior left ventricular artery (PLV). (C, D) A repeat coronary angiogram was performed 6 weeks later. She was found to have complete resolution of SCAD in the LAD and PLV.

Coronary angiogram revealed tortuous vessels with evidence of spontaneous coronary artery dissection (SCAD) in multiple coronary arteries including the left anterior descending artery, posterior descending artery (PDA), and posterior left ventricular artery (Fig. 1, A and B; Video 1 ; view video online). SCAD. She was found to have complete resolution of SCAD in the left anterior descending artery and posterior left ventricular artery (Fig. 1, C and D). Interestingly, the PDA displayed a "string of beads" appearance suggestive of coronary artery FMD (Figs. 1D and 2C).
Fibromuscular dysplasia. (A) A renal angiogram was performed, which demonstrated a "beading" appearance of the right renal artery consistent with renal artery fibromuscular dysplasia (FMD). (B) A head computed tomography angiogram was performed, which showed evidence of FMD of the bilateral vertebral arteries. (C) On repeat coronary angiogram, the posterior descending artery displayed a "string of beads" appearance suggestive of coronary artery FMD.

Because of the known association of SCAD and fibromuscular dysplasia (FMD), a renal angiogram was performed, which demonstrated a "beading" appearance of the right renal artery consistent with renal artery FMD (Fig. 2A; Video 2 ; view video online). A head computed tomography angiogram showed evidence of FMD of the bilateral vertebral arteries (Fig. 2B). Interestingly, the PDA displayed a "string of beads" appearance suggestive of coronary artery FMD (Figs. 1D and 2C).
