Intraoperative photograph showing the simplicity of the technique and perfusion of grafts and coronary sinus. (A = antegrade cannula; R = retrograde cannula; Ra = radial artery to posterior descending artery being perfused by a multiport from the ascending aorta; RA = right atrium; Rima = right internal mammary artery to right coronary artery graft.)
