“…The clinical applications of autologous human pericardial tissue have included AVr, aortic root enlargement, and LV aneurysm repair. 1,9,10,18 Because APP has characteristics similar to those of human pericardial tissue, APP was used in the present study as a surrogate to human pericardium. 19 The APP used was derived from fresh porcine pericardium and had poor handling qualities owing to its fragile structure.…”

The present study has shown that postrepair left ventricular work did not increase despite a decrease in geometric orifice areas in the Hemashield and CorMatrix groups. The autologous porcine pericardium and St Jude Medical pericardial patch had the closest profile to normal AVs; therefore, either biomaterial might be best suited. Finally, the increased stresses found in the bovine pericardial patch, Hemashield, and CorMatrix groups might, after prolonged tensile exposure, be associated with late repair failure.

“…Understanding the mechanisms of aortic valve dysfunction and the aetiology of lesions has greatly aided surgeons in the development of repair techniques. Several surgical repair approaches have been described to correct AI, and long-term results for these different operative techniques have been previously reported [7][8][9][10]16].…”

FAVA remodelling using a prosthetic ring is a safe procedure in aortic valve repair surgery thanks to long-term annulus stabilization and it is a pliable alternative to David's procedure in selected patients. This technique may be used in all patients with slight root dilatation to avoid aggressive root reimplantation. We also recommended total FAVA annuloplasty in all patients who underwent aortic valve repair to improve long-term repair results.

Twenty-four studies conformed to the inclusion criteria for inclusion in the systematic review. In total, 4986 patients underwent aortic valve repair. 7 studies represented bicuspid aortic valve (BAV) repair, 5 studies represented cusp prolapse, and 3 studies represented valve repair with root dilation or aneurysm. Overall weighted in-hospital mortality for all studies was low (1.46% ± 1.21). Preoperative aortic insufficiency (AI) ≥ 2+ did not correlate to reoperation for valve failure (Pearson's Rs 0.2705, P = 0.2585). AI at discharge was reported in 9 studies with a mean AI ≥ 2+ in 6.1% of patients. Weighted average percentage for valve reoperation following BAV repair was 10.23% ± 3.2. Weighted average reoperation following cusp prolapse repair was 3.83 ± 1.96. Weighted average reoperation in aortic valve sparing procedures with root replacement was 4.25% ± 2.46. Although there are limitations and complications of prosthetic valves, especially for younger individuals, there is ample published literature that confers strong evidence for AVR. On the contrary, aortic valve repair may be a useful option for selected patients, but there is lack of uniformity in data and absence of compelling supporting evidence. An international multi-center study comparing and assessing the results between AVR & AVr is the next step required. Currently, higher levels of evidence do not exist for aortic valve repair.
