Follow-up coronary angiography

<p>Fig. 1a. SVGD (⇑) in the graft implanted to the obtuse marginal branch of the circumflex artery in a 58-year old man admitted to a regional hospital due to unstable angina 27 months after surgery. The morphometric analysis of this SV segment obtained intraoperatively (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070628#pone-0070628-g002" target="_blank">Figure 2a</a>) revealed marked hypertrophy of the SV wall (WallTh 475.8 µm and WallAr 2.58 mm<sup>2</sup>) and its media (MedTh 329.2 µm and MedAr 1.43 mm<sup>2</sup>). The mean length/width index of the representative medial SMC nuclei was 5.7. Fig. 1b. Angiography of a normal SV aortocoronary bypass graft to the circumflex artery of a 75-year-old female patient without clinical symptoms of CAD deterioration performed 47 months after CABG. The results of the morphometric study (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070628#pone-0070628-g002" target="_blank">Figure 2b</a>) were as follows: WallTh 329.2µm, WallAr 1.55 mm<sup>2</sup>, MedTh 199.8 µm, MedAr 0.60 mm<sup>2</sup>. The SMC nuclei were spindle-shaped with a mean length/width index of 10.1. Abbreviations: Cx – circumflex artery; OMCx – obtuse marginal branch of the circumflex artery; SVgraft – saphenous vein bypass graft.</p
