1 Correction of Aortic Insufficiency With an External Adjustable Prosthetic Aortic Ring 
Andrew Gogbashian, MD, Ravi K. Ghanta, MD, Ramanan Umakanthan, MD, Aravind T. Rangaraj, MD, Rita G. Laurence, BS, John A. Fox, MD, Lawrence H. Cohn, MD, Frederick Y. Chen, MD, PhD  The Annals of Thoracic Surgery  Volume 84, Issue 3, Pages (September 2007) DOI: /j.athoracsur Copyright © 2007 The Society of Thoracic Surgeons Terms and Conditions

2 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.)

3 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.)

4 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. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2007 The Society of Thoracic Surgeons Terms and Conditions

5 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).

6 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.)
