Echocardiographic and Computed-tomographic Evaluation of the Fate of Bovine Pericardial Patch as a Pericardial Substitute in Bentall’s Procedure: Twenty-year’ Results

Objective: The study was designed to ascertain the influence of usage bovine pericardial patch in patients undergoing Bentall’s procedure with respect reexploration for bleeding, mediastinal infection, avoidance conduit adhesions, late development constriction and calcification. Materials Methods: We reviewed 150 (79 males) aged between 22 68 years (mean±SD 49.25±12.9 years) receiving a composite aortic January 1998 December 2020 annuloaortic ectasia (n=100), dissection (n=49), dilated root repaired tetralogy Fallot (n=1). Twenty-five had Marfan’s syndrome. Modified “button technique” performed by interposing glutaraldehyde treated strip at graft coronary anastomoses, proximal suturing using interlocking interrupted, pledgeted mattress suture. On completion, cavity reconstructed St. Jude Medical Biocor patch. To detect evidence constriction, survivors underwent echocardiography computed tomography. Kaplan-Meier curve drawn show probability survival over period follow-up time. Results: Seven (4.7%) died cardiac-related cause, 45% transient hemodynamic instability, 55% low cardiac output, 87.1% spontaneous return sinus rhythm. average 12-hour postoperative drainage 245±70 ml there no infection. At mean 172.4 (SD± 58.9) months, actuarial 94.2±0.04% (95% CI: 88.5-96.8), or Conclusion: Reconstruction minimizes diffuse oozing blood, is not associated later
