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.

Valve Sparing

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.

AbstractOBJECTIVESAortic root and ascending aorta replacements (AARs) are rarely required in the paediatric population. We report here a series of AAR performed in young children using different surgical techniques.METHODSBetween 1995 and 2017, 32 children under the age of 10 years (median age 5.4 years) underwent AAR procedures at our institution. Twenty-two (69%) had a connective tissue disease (infantile Marfan syndrome or Loeys–Dietz syndrome). We performed 11 AAR using a composite graft with a mechanical prosthesis and 21 valve-sparing procedures (10 Yacoub operations and 11 David operations). Median follow-up for operative survivors was 7.7 years (interquartile range 4.2–12.8 years).RESULTSThe cardiac-related early mortality rate was 6%. Patient survival was 91% at both 1 and 10 years. Eleven survivors (38%), all with a status of post-valve-sparing procedure, required an aortic root reintervention with an aortic valve replacement after a median interval of 4.2 years. Interestingly, only patients with infantile Marfan syndrome tended to be associated with risk of reoperation.CONCLUSIONSAortic root and AARs are safe in young children whatever the surgical procedure. Aortic valve-sparing procedures show good long-term results except in children with infantile Marfan syndrome whose ineluctable aortic annulus dilatation or aortic valve regurgitation requires reintervention after a short period.

Abstract Introduction and objectives Bicuspid aortic valve (BAV) is the most common congenital malformation, with an estimated prevalence ranging from 0,48 to 2%. Most of the studies describe complications associated with BAV, including aortic stenosis and regurgitation, infective endocarditis and aortic dilation and dissection. Very few studies have been performed in the neonatal and paediatric age, most lacking in long-term follow up. The aim of our study was to explore the prevalence of BAV and the progression of aortic valve disease and aortic dilation in paediatric patients followed from January 1996 to August 2018. Methods A prospective collection of Congenital Heart Disease (CHD) diagnosed in the first year of life was performed in our institution from January 1996 to August 2018. Patients affected by BAV were then followed yearly. BAV morphology, aortic valve dysfunction and aortic dimensions were measured. Comparisons were performed between right-left cusp fusion (R-L) and right-non coronary cusp fusion (R-N), according to Shaefer's classification. Rate of change of the ascending aorta size over time was analyzed, and aortic size values were normalized as the number of standard deviations above or below the mean size expected for body surface area (z scores). Results A total of 35,310 live births were screened. Incidence rate of total CHD, including small ventricular septal defects and BAV was19,57%. Sixty had BAV (8,73% of CHD), with an incidence of 17/1,000 live births. Male/Female ratio was 1.4. A positive family history was present in 5 (8.3%). In 12 patients (24%) BAV was associated to other CHD (9 Aortic Coarctation, 1 Atrio-Ventricular Septal Defect, and in two cases a critical neonatal aortic stenosis). BAV was isolated in 48 cases (80%), with an incidence of 13.6/1.000 live births. According to Shaefer's classification the most common was type 1 (R-L), with Right to Left cusps fusion (R-L 76%, R-N 21% and L-N 3%). Among patients with isolated BAV, after a median follow up of 11 [1–21] years an aortic stenosis was observed in 5 patients (10.4%, none severe), an aortic insufficiency in 13 (27%, in one case severe). A dilated ascending aorta (z-score>2) was found in 11 patients (23%). An indication cardiac surgery due to severe aortic insufficiency was present in one case. No patient had indication for aortic aneurysm surgery. Conclusions Paediatric patients with isolated BAV warrant medical follow-up but progression towards severe valve dysfunction and/or dilation of the ascending aorta warranting cardiac surgery is very low.

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.

Background The Ross operation for aortic valve replacement continues to be a controversial option because of concerns related to late autograft dilation and progressive neo-aortic insufficiency. In 2005, the reinforced Ross procedure was described at our institution to address this problem. We aim to analyze the short and mid-term outcomes following this procedure. Methods This is a retrospective study of patients who underwent the reinforced Ross operation between 2004 and 2019. A comprehensive chart review was performed. Echocardiograms were independently reviewed by an adult congenital cardiologist. The time to reintervention was evaluated with a Kaplan-Meier curve. Analysis was conducted in JMP 15.1 (SAS Inc., Cary, NC). Results Twenty-five patients underwent the reinforced Ross operation. Twenty-three patients (92%) had bicuspid aortic valve and the most common indication for surgery was a combination of aortic insufficiency and stenosis (n = 18, 72%). The mean follow-up was 6.1 ± 5.0 years. All patients were alive at the time of follow-up. Six patients (24%), from early in our experience, required subsequent aortic reintervention. Median time to reintervention was 41.8 months (0-81.5 months). Sixteen (64%) patients had less than moderate aortic insufficiency at last follow-up. Additionally, average aortic root measurements remained unchanged. Conclusions The reinforced Ross technique was initially proposed as a way to mitigate aortic root dilation seen in the traditional Ross procedure. Our experience suggests an associated learning curve with the majority of aortic reinterventions occurring within the first few years following surgery. Continued follow-up is warranted to assess its long-term durability and functionality.

Aortic valve (AV) sparing surgery is an attractive option for the treatment of aortic root pathology. However, presence of significant preoperative aortic insufficiency (AI) or the need for cusp repair has been associated with poorer outcome. We analyze the influence of preoperative AI severity and the need for cusp repair on the early and mid-term outcomes of AV sparing surgery. From 1996 to 2007, 134 consecutive patients underwent elective AV sparing surgery. (mean age − 52±16 years; 84% male). Significant preoperative AI (3+ or 4+) was present in 83 patients (62%) and 46 (34%) had a bicuspid valve. Root repair was performed with either the reimplantation (67%) or remodeling technique (33%). A systematic approach was used for intraoperative valve assessment and cusp repair was performed in 74 patients (55%). Clinical and echocardiographic follow-up was complete in 100% and 96% respectively at a mean follow-up time of 57 months (range: 12–147 months). Kaplan-Meier curves, log rank test, and Cox regression analyses were used. Hospital mortality was 0.7%. AV cusp repair was required in 53% of patients without significant AI and in 57% with significant AI (p=0.9). Cusp repair was required more frequently in bicuspid versus tricuspid valves (89% vs. 38%, p = 0.005). Overall survival at 5 and 8 years was 94±5% and 86±10% respectively. Freedom from recurrent AI (>2+) was similar with or without significant preoperative AI (90±10% vs. 86±10% at 5 years, p=0.5) and with or without cusp repair (87±11% vs. 89±10%, p=0.6; Figure 1). Freedom from AV reoperation at 5 years was similar with or without significant preoperative AI (94±6% vs. 89±8%, p=0.5) and with and without cusp repair (90±9% vs. 91±8%, p=0.8). With a systematic approach to valve assessment and cusp repair, AV sparing surgery for aortic root pathology has an acceptable early and mid-term outcome, irrespective of preoperative AI or need for cusp repair. Cusp repair is not predicted by presence of preoperative AI but is more frequent in bicuspid valves. Preoperative AI should not be considered a contra-indication for valve sparing surgery.

Background We sought to determine if a modified technique for ascending aorta replacement with sinotubular junction reduction and stabilization was safe. Methods This technique was performed by suspension of the three commissures, invagination of the aortic Dacron graft and advancing the graft into the ventricles. We included patients with dilatation of the ascending aorta, normal sinuses of Valsalva dimension (<45 mm), with or without aortic annulus enlargement (>25 mm) and with various degree of aortic insufficiency (from grade 1 to 3). Results From April to October 2019, 20 patients were recruited from two centers; mean age was 66.9 ± 12.8 years, 13 were male; grade 1, 2 and 3 was present in 12, 2 and 6 patients, respectively. All patients underwent ascending aorta replacement with modified technique; an additional open subvalvular ring was used in 8 patients with aortic insufficiency ≥ 2; cusps repair was performed in 6 patients (5 plicating central stitches/1 shaving); concomitant coronary artery bypass grafting was performed in 10 patients. There was no 30-day mortality. One patient was re-explored for bleeding. All patients completed six-month follow-up; at the transthoracic echocardiography, there was no aortic insufficiency ≥ 1 except one patient with aortic insufficiency grade 1 who underwent ascending aorta replacement and subvalvular ring; no patients underwent reintervention. Conclusions This modified technique for ascending aorta replacement and sinotubular junction stabilization was safe. It could be associated with other aortic valve sparing techniques. However, such remodeling approach has to be validated in a larger cohort of patients with longer follow-up.

Background —We have previously described the experience, rationale, and development of a valve preserving technique, but its role in patients with Marfan syndrome has not previously been defined. Here, we attempt to determine the early and long-term results, timing, and determinants of outcome of this operation in patients with Marfan syndrome. Methods and Results —Since 1979, 82 patients (73.2% of all patients with Marfan syndrome undergoing resection of aneurysm of the ascending aorta) were operated on using this technique. Ages ranged from 2 to 69 years (mean, 33.9 years). In all, there were 4 early deaths (4.9%), 2 with acute dissection and 2 with chronic aneurysm operated on as emergencies. There were no early deaths in 67 patients operated on electively. Actuarial survival for patients operated for chronic aneurysm was 94.2%, 94.2%, and 94.2% at 1, 5, and 10 years, respectively; that for acute dissection was 72.7%, 63.6%, and 63.6%; and that for chronic dissection was 100%, 85.7%, and 75.0%. The probability of needing reoperation was 5.7%, 17.3%, and 17.3% at 1, 5, and 10 years. There were no instances of infective endocarditis or thromboembolic complications except in 2 patients operated on early in the series who had cusp extension. At the end of the follow-up, trivial or no aortic regurgitation was demonstrated in 33.3%, mild in 45.6%, moderate in 21.1%, and severe in 0. Conclusions —Valve-sparing operations are feasible in most patients with Marfan syndrome; they are applicable to patients with both dissection and chronic aneurysm. The early and long-term results are encouraging. Results are better in the absence of dissection, and prophylactic operation is warranted in some cases.
