Aortic valve neocuspidization with fixed autologous pericardium according to the Ozaki technique has been proven to be an effective therapy for the treatment of aortic valvulopathies of various entities (aortic stenosis, aortic regurgitation, aortic valve endocarditis) in both tricuspid and bicuspid aortic valves. Thus, aortic valve neocuspidization with fixed autologous pericardium represents a versatile alternative to complex aortic valve repair, with better hemodynamics compared to biological aortic valve replacement and without the need for lifelong anticoagulation, which characterizes mechanical aortic valve replacement. The authors meticulously describe all the technical steps of this highly reproducible, standardized procedure.

We report a case of an 18-year-old female who presented with severe aortic stenosis and insufficiency, eight years following resection of a subaortic membrane. On echocardiography, she was found to have a completely fused or nullicuspid valve, with three equal sinuses and three commissural fusions. Aortic valve repair included leaflet tricuspidization, three commissurotomies, trileaflet ring annuloplasty, and pericardial leaflet reconstruction. At one year follow-up, the patient is asymptomatic, with stable gradients.

Quadricuspid aortic valve (QAV) is a rare congenital anomaly often associated with aortic insufficiency. The exact anatomy of QAV is variable, and most cases have undergone aortic valve replacement. With the recognition that aortic valve repair achieves superior patient outcomes as compared to replacement, a systematic approach to autologous reconstruction of QAV is needed. This article reports 2 cases having successful repair utilizing geometric aortic annuloplasty rings, and describes a proposed scheme for repairing most QAV defects, based on relative leaflet and commissural characteristics. Using either tri-leaflet or bicuspid ring annuloplasty, the normal sub-commissural triangles can be remodeled into a 120° or 180° configuration, respectively, and then the leaflets can be sutured and plicated to fit annular geometry. With this approach, most quadricuspid valves potentially could undergo autologous reconstruction.

Abstract   OBJECTIVES The aim of this study was to compare the outcomes of tricuspid aortic valve (TAV) and bicuspid aortic valve (BAV) repair. METHODS We assessed mortality, freedom from reoperation and the rate of aortic valve regurgitation recurrence. Mortality in both groups was compared with expected survival, and risk factors for reoperation were identified. RESULTS From January 2010 to April 2020, a total of 368 elective aortic valve repair procedures were performed, including 223 (60.6%) in patients with TAV. The perioperative mortality was 0.7% in the BAV group and 3.6% in the TAV group (P = 0.079). Estimated survival at 5 years in the BAV versus TAV group was 97 ± 3% vs 80 ± 6%, respectively (P < 0.001). Freedom from reoperation at 5 years in the TAV versus BAV group was 96 ± 3% vs 93 ± 4%, respectively (P = 0.28). Grade 2 or more aortic valve regurgitation was noted in 9.9% of BAV patients and 11% of TAV patients (P = 0.66). Reoperation was predicted by cusp perforation [hazard ratio 15.86 (4.44–56.61); P < 0.001], the use of pericardial patch [hazard ratio 8.58 (1.96–37.53); P = 0.004] and aortic valve annulus diameter >27.5 mm [hazard ratio 3.07 (0.99–9.58); P = 0.053]. CONCLUSIONS BAV repair is as durable as TAV repair. BAV is not a predictor of a higher rate of reoperations. BAV repair yields survival comparable to expected. Cusp perforation, aortic valve annulus diameter >27.5 mm and the use of pericardial patch adversely impact long-term outcome of aortic valve repair.
