Fig 1 Illustration of the external aortic ring experimental device. A hardened nylon band is looped around the aorta and through a latex buckle. The free ends of the band are secured to an adjustable sizer. The ring circumference can be adjusted by sliding the band through the buckle in a controlled manner. For this study, the ring was passed underneath the right and over the left coronary arteries. (LCA = left coronary artery; RCA = right coronary artery.)

Fig 2 Patch plasty enlargement of the aortic root. A pericardial patch is interposed between the right and noncoronary aortic valve leaflets, causing separation at their coaptation edges. This models a dilated aortic root as a cause of aortic insufficiency. (Arrow indicates pericardial patch; NCL = noncoronary leaflet; RCL = right coronary leaflet; RCO = right coronary ostium.)

Fig 3 (a) Recording of aortic flow in one sheep with aortic regurgitation. The hatched area represents the area measured to determine regurgitant volume. (b) Aortic flow after ring device tightened.

Fig 4 Acute effects of the external aortic ring device in sheep. Depicted are the individual values for each animal: (left) regurgitant fraction (%) decreased with application of the aortic ring (p < 0.01), and (right) the hemodynamic regurgitant orifice area (cm2) decreased with application of the aortic ring (p < 0.01).

Fig 5 Two-dimensional epicardial echocardiograms: the acute effect of the aortic ring device on aortic regurgitation. (a) Ring off: diastolic regurgitant color flow Doppler signal extending into left ventricle. (b) Ring off: short-axis view demonstrating central and eccentric flow between the right and noncoronary cusps. (c) Ring on: trivial regurgitant flow during diastole with almost complete elimination of aortic insufficiency. (d) Ring off: reproducible, regurgitant flow in diastole after loosening of device. (Arrow indicates regurgitant Doppler jet; LA = left atrium; LV = left ventricle; RV= right ventricle.)
