Background: Pediatric aortic root dilatation is a life-threatening condition that lacks guidelines for surgical management. We aimed to analyze the data on aortic valve interventions during root surgery to guide decision-making. Methods: A search was performed of MEDLINE, Embase, CENTRAL, ClinicalTrials.gov , and WHO ICTRP. Citations were screened in duplicate and independently to identify randomized controlled trials, cohorts, and case series involving populations aged 0 to 18 years, who received valve-sparing and valve-replacing aortic root surgeries between 1999 and 2019. Outcomes considered included mortality (perioperative, one year, five year), reintervention rates. Results: After duplicate removal, 689 citations were screened through abstract and full text review, identifying five eligible studies. All five were observational studies evaluating valve-sparing procedures. There were 81 patients with a mean study age range of 9.9 to 13.9 years. Both reimplantation (74%) and remodeling (26%) subtypes were done. Range of mean duration of follow-up was 1.2 to 4.4 years. There was no mortality reported until the one-year follow-up period. The long-term mortality rate was calculated as 0.02 per patient-year (95% CI: 0.01-0.05). The long-term reintervention rate was 0.08 per patient-year (95% CI: 0.05-0.13). Conclusions: There is limited experience on aortic valve intervention during aortic root surgery in children. Single-arm studies on valve-sparing surgeries show excellent survival up to one year. Mortality and reintervention rates increase in the longer term. The small sample size and lack of controlled studies do not allow for direct comparisons between procedure types.

Abstract The aim of this paper is to report histologic and tomographic findings of fresh frozen bone block allografts bearing dental implants in functional occlusion in a long-term follow-up. Four patients with implants functionally loaded for 4 years on augmented ridges requiring additional mucogingival surgery or implant placement were included in this case series. Cone-beam tomography scans were compared volumetrically between the baseline (first implant placement) and current images. Biopsies of the grafts were retrieved and sent to histological analysis. Volumetric reduction of the grafts varied from 2.1 to 7.7%. Histological evaluation demonstrated well-incorporated grafts with different degrees of remodeling. While data presented in this report are from a small sample size and do not allow definitive conclusions, the biopsies of the grafted sites were very similar to the host's native bone. Remodeling of the cortical portion of the allografts seems to take longer than the cancellous portion. The presence of unincorporated graft remains did not impair the implant success or the health of the surrounding tissues. This is the first time histologic and tomographic long term data of bone allograft have been made available in dentistry.

Objective: Valve-sparing root replacement is commonly used for management of aortic root aneurysms in elective setting, but its technical complexity hinders its broader adoption for acute Type-A Aortic Dissection (ATAAD). The Florida Sleeve (FS) procedure is a simplified form of valve sparing aortic root reconstruction that does not require coronary reimplantation. Here, we present our outcomes of the Florida Sleeve (FS) repair in patients with dilated roots in the setting of an ATAAD. Methods: We retrospectively reviewed 24 consecutive patients (2002-2018) treated with FS procedure for ATAAD. Demographic, operative, and postoperative outcomes were queried from our institutional database. Long term follow-up was obtained from clinic visits for local patients, and with telephone and telehealth measures otherwise. Results: Mean age was 49 ± 14 years with 19 (79%) males. Marfan syndrome was present in 4 (16.7%) patients and 14 (58.3) had ≥2+ aortic insufficiency (AI). Nine (37.2%) had preoperative mal-perfusion or shock. The FS was combined with hemi-arch replacement in 15 (62.5%) patients and a zone-2 arch replacement in 9 (37.5%) patients. There were 2 (8.3%) early postoperative mortalities. Median follow-up period was 46 months (range; 0.3-146). The median survival of the entire cohort was 143.4 months. One patient (4.2%) required redo aortic valve replacement for unrelated aortic valve endocarditis at 30 months postoperatively. Conclusion: FS is simplified and reproducible valve-sparing root repair. In appropriate patients, it can be applied safely in acute Stanford type-A aortic dissection with excellent early and long-term results.

Abstract Introduction: Aorto-left ventricular tunnel is a rare disease that can cause significant morbidity early in life due to volume overload and left ventricular failure. Surgical intervention is usually curative with minimal early complications. However, long-term effects and outcome are not fully determined. Objective: We are reporting a case series of this rare CHD with its long-term outcome. Methods: We conducted a retrospective analysis of all children from birth to 14 years of age who were admitted between 2001 and 2020 with the diagnosis of aorto-left ventricular tunnel. Demographic, echocardiographic, and perioperative data were collected and reviewed. The pre-operative data were compared with data reviewed on the last outpatient follow-up. Results: Total of five patients fulfilled our inclusion criteria. Three patients were diagnosed after auscultating an incidental murmur, one had symptoms of congestive heart failure, and one had an abnormal fetal echocardiogram. Echocardiography demonstrated stenotic and regurgitant aortic valve with severely depressed left ventricle function in two patients, one of them with also single left coronary artery. The other three patients had normal aortic valve structure and normal ventricular function. All five patients had surgical repair, two by patch closure at aortic end of aorto-left ventricular tunnel, two by patch closure at both aortic and left ventricular ends, and one by aortic root replacement using a homograft. During follow-up, there was no residual aorto-left ventricular tunnel in any of our five cases, two had moderate aortic regurgitation and one had moderate residual aortic stenosis. Conclusions: Spectrum of presentation for aorto-left ventricular tunnel varies from an occult lesion to frank left heart failure due to volume or less commonly, pressure overload. Early surgical repair is recommended and is usually associated with complete resolution. Long-term follow-up is recommended for aortic root dilatation and aortic valve competency, as valve function need to be addressed in a timely manner to avoid further complications.

Introduction: To evaluate early and long-term clinical outcomes following aortic valve sparing aortic root reimplantation surgery in patients with leaking bicuspid and tricuspid aortic valves. Methods: The study consisted of 92 consecutive adult patients (tricuspid aortic valve group = 63 and bicuspid aortic valve group = 29) who underwent aortic valve sparing aortic root reimplantation surgery with or without aortic cusp repair for dilatation of the aortic root and/or aortic valve regurgitation at our institution from April 2004 to October 2016. Clinical outcomes were investigated using Kaplan–Meier and log-rank tests between groups. Results: The follow-up was 100% complete with a mean time of 5.3 ± 3.3 years. The 30-day in-hospital mortality was 3.1% in tricuspid aortic valve group and 3.4% in bicuspid aortic valve group patients. The overall survival rates at 10 years did not differ between bicuspid aortic valve and tricuspid aortic valve patient groups (96.6 ± 3.3% vs. 90.3 ± 4.2%, p = 0.3). Freedom from recurrent aortic valve regurgitation (>2+) at 10 years was 90.5 ± 4.1% in tricuspid aortic valve group and 75.7 ± 8.7% in bicuspid aortic valve group (p = 0.06). Freedom from aortic valve reoperation at 10 years was 100% in tricuspid aortic valve group and 83.9 ± 7.4% in bicuspid aortic valve group (p = 0.002). Conclusion: Aortic valve sparing aortic root reimplantation surgery is a safe and efficient technique, providing acceptable long-term survival with low rates of valve-related complications in both tricuspid aortic valve and bicuspid aortic valve patient groups. However, aortic valve reoperation rates at 10 years follow-up were higher in bicuspid aortic valve group patients compared to tricuspid aortic valve group patients.

Abstract OBJECTIVES Aortic valve-sparing root replacement is an excellent treatment option for patients with intact tricuspid aortic valves. However, the durability in patients with bicuspid aortic valves is still a matter of debate. The aim of this study was to analyse the short- and long-term outcomes in patients with bicuspid aortic valves. METHODS Between July 1993 and October 2015, a total of 582 patients underwent the David I procedure, 50 of whom had a bicuspid aortic valve. In these patients, the mean age was 46 ± 13 years, and 80% (n = 40) were men. Follow-up was complete for 100% of patients and comprised a total of 552 patient-years with a mean follow-up time of 11 ± 5.2 years. RESULTS In addition to the David procedure, cusp plication was performed in 34% (n = 17) of patients and commissure repair in 8% (n = 4) of patients. There were no in-hospital deaths, and 1 patient (2%) had a perioperative stroke. The 1-, 5-, 10- and 20-year survival rates of patients after discharge were 98%, 94%, 88% and 84%, respectively. The rates for freedom from valve-related reoperation at 1, 5, 10 and 20 years after initial surgery were 98%, 88%, 79% and 74%, respectively. Long-term freedom from reoperation was comparable to that of patients with tricuspid aortic valves (P = 0.2). CONCLUSIONS The David procedure has excellent short-term results in patients with a bicuspid aortic valve. In this study, the long-term durability of reimplanted bicuspid aortic valves was comparable to that of tricuspid valves. However, careful patient selection might have contributed to this, and further studies might be needed to definitely clarify this issue.

Introduction. To evaluate outcomes of wide-diameter (6 mm) implants immediately provisionalized with cement-retained single crowns in posterior molar sites.Materials and Methods. Forty-eight consecutive patients received a total of 53 moderately rough-surface, 6 mm diameter implants in healed sites. All implants were immediately provisionalized with a cement-retained provisional crown. Final prosthesis with cement-retained porcelain fused to metal crowns was delivered 3–6 months later. Patients were followed up for 1 year. Outcome measures were implant failures and success rate, complications, marginal bone levels, bone level changes, papilla index, bleeding on probing, and inflammation.Results. One patient was lost to follow-up. At one year, the implant survival and success rate were 98.1%. The mean marginal bone loss after 1 year was −0.17±1.84 mm. Ideal papilla score was recorded at 83.8% of the sites. More than 95.6% of the sites showed no bleeding or inflammation. No procedure-related or device-related adverse events were reported.Conclusion. Wide-diameter (6 mm) implants can safely and successfully replace single posterior molars. Longer follow-up studies are necessary to evaluate the long-term success of these implants.
