Abstract
BACKGROUND Cardiovascular involvement in pediatric patients with connective tissue disease (CTD) is life-threatening, with aortic root dilatation being the most prevalent cardiovascular abnormality. We attempted to determine long-term outcomes of valve-sparing root replacement (VSRR) in this group, including cardiovascular reoperations for aortic aneurysm and dissection. METHODS We conducted a retrospective analysis of pediatric patients with CTD who received VSRR in a single center from 2002 to 2021. The primary end point was a composite event of all-cause death and cardiovascular reoperations. The median follow-up duration was 8.3 years, with a maximum of 20.7 years. RESULTS The median age of 24 pediatric patients who had VSRR was 14.4 years. Marfan syndrome and Loeys-Dietz syndrome affected 19 (79.2%) and 5 (20.8%) patients, respectively. There was no early death. The 15-year survival rate was 91.7%. At 10 years after VSRR, the cumulative incidence of reoperation for aortic regurgitation was 15.6%, and for aortic aneurysm or dissection, it was 29.1%. The 10-year rate of freedom from the primary end point was 53.1%. The Cox multivariable analysis revealed younger age at surgery (hazard ratio, 1.279; 95% confidence interval, 1.086-1.505; P = .003) and VSRR before 13 years of age (hazard ratio, 5.005; 95% confidence interval, 1.146-21.850; P = .032) as independent prognostic factors for the primary endpoint. CONCLUSIONS VSRR for aortic root dilatation in pediatric patients with CTD demonstrated good long-term survival and low reoperation rates for aortic regurgitation. However, several patients developed later aortic aneurysm or dissection, and careful surveillance may be required, particularly in those who received VSRR at younger age.

Abstract
In this invited expert review, we focus on evolving lifetime management strategies for adolescents and young adults with congenital aortic valve disease, acknowledging that these patients often require multiple interventions during their lifetime. Our goal is to preserve the native aortic valve when feasible. Leveraging advanced multimodality imaging, a detailed assessment of the aortic valve and root complex can be obtained, and a surgically approach tailored to an individual patient's anatomy and pathology can be used. In turn, aortic valve repair and reconstruction can be offered to a greater number of patients, either as a definitive strategy or as a component of a staged strategy to delay the need for aortic valve replacement until later in life when more options are available.

Indian J Thorac Cardiovasc Surg 2024; 40:107-110. [PMID: 38125325 PMCID: PMC10728024 DOI: 10.1007/s12055-023-01629-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 10/16/2023] [Accepted: 10/16/2023] [Indexed: 12/23/2023] Open
Abstract
Although there have been great improvements in the short- and medium-term outcomes of the arterial switch operation (ASO) for transposition of the great arteries (TGA), some complications including pulmonary artery stenosis, aortic valve insufficiency, and aortic root dilatation have also been reported. After ASO, the original pulmonary root and valve, which function in the systemic position as the neo-aortic root and valve respectively, are exposed to the systemic blood pressure, resulting in aortic root dilatation and valve insufficiency in some patients. One of the risk factors for these complications is a history of prior pulmonary artery banding (PAB). Complex TGA anatomy, including transposition of the great arteries and ventricular septal defect (TGA-VSD) or double outlet right ventricle and ventricular septal defect (DORV-VSD), is also an independent risk factor for neo-aortic dilatation and aortic valve regurgitation. Aortic valve and root replacement is sometime necessary for the patients with these pathologies long-term after ASO. Here, we present a patient who had persistent aortic sinus dilatation and aortic valve insufficiency since ASO and necessitating aortic root and valve replacement 15 years after ASO preceded by PAB. The patient underwent Bentall operation and his clinical course was favorable. Histological findings after root replacement revealed no remarkable structural difference between neo-aortic wall (originally pulmonary artery) and original aortic wall.

Abstract
Connective tissue disorders can be associated with significant cardiovascular morbidity needing cardiac surgery during childhood. In this retrospective study, we used the Pediatric Cardiac Care Consortium, a multicenter United States-based registry of pediatric cardiac interventions, to describe the long-term outcomes of patients who underwent their first surgery for connective tissue-related cardiovascular conditions aged <21 years. Between 1982 and 2003, a total of 103 patients were enrolled who underwent cardiac surgery for a connective tissue-related cardiovascular disorder, including 3 severe infantile cases operated on within the first year of life. Most patients underwent aortic site surgery (n = 85) as a composite graft (n = 50), valve-sparing (n = 33), or other aortic surgery (n = 2). The remaining patients underwent atrioventricular valve surgery (mitral 17, tricuspid 1). Of the 99 patients surviving to discharge, 80 (including the 3 infantile) had adequate identifiers for tracking long-term outcomes through 2019 through linkage with the National Death Index and the Organ Procurement. Over a median period of 19.5 years (interquartile range 16.0 to 23.1), 29 deaths and 1 transplant occurred in the noninfantile group, whereas all 3 infantile patients died before the age of 4 years. The postdischarge survival for the noninfantile group was 92.2%, 68.2%, and 56.7% at 10, 20, and 25 years, respectively. Cardiovascular-related pathology contributed to all deaths in the infantile and 89% (n = 27) of deaths for the noninfantile cases after hospital discharge. The significant late attrition from cardiovascular causes emphasizes the need for close monitoring and ongoing management in this population.

Abstract
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
OBJECTIVES Some studies have suggested that root remodelling is unsuitable as valve-sparing aortic root replacement in children because of the increased risk of valve failure. This study reviewed our experience with root remodelling in children. METHODS All patients who underwent root remodelling at the age of ≤18 years between 1999 and 2016 were evaluated. In 2004, cusp effective height was measured intraoperatively and prolapse was corrected with central plication on the cusp. Suture annuloplasty was introduced after 2009 for annular dilatation. RESULTS There were 17 consecutive patients. The median age at operation was 14 (2.8-18) years. Aortic valve morphology was tricuspid in 10 patients, bicuspid in 5 patients, unicuspid in 1 patient and a pulmonary autograft in 1 patient. Marfan syndrome, Loeys-Dietz syndrome and other connective tissue diseases were present in 11, 1 and 2 patients, respectively. Five patients had more than moderate aortic regurgitation. The median graft size used for root remodelling was 24 (18-26) mm. Cusp repair and annuloplasty were performed in 15 and 14 patients, respectively. The mean follow-up time was 6.5 ± 4.3 years. One patient with preoperatively severely depressed ventricular function died in the hospital from persistent heart failure. One patient (operated on before 2004) required aortic valve reoperation due to cusp prolapse. One patient with a unicuspid valve had developed moderate aortic regurgitation, and the other 14 patients had mild or less regurgitation. The median diameter of the sinus of Valsalva at the last follow-up was 36 (30-43) mm, Z-score of 1.5 (-3.5 to 3.9). CONCLUSIONS Root remodelling can be performed in children with favourable results by appropriate cusp repair and annuloplasty.

Abstract
Patients with Marfan syndrome (MFS) often require surgical intervention on the mitral valve (MV), aortic root or valve (AV), or thoracic aorta (TA) during childhood and adolescence. We aim to utilize a national database to evaluate outcomes in pediatric and young adult patients with MFS undergoing MV, AV, and aortic surgical procedures, and describe factors associated with increased mortality. The Pediatric Hospital Information System (PHIS) database, a multi-institutional administrative database of 48 pediatric hospitals, was queried for patients less than 25 years of age with a diagnosis of MFS (ICD-9 759.82) who underwent MV, AV, or thoracic aortic surgery between January 2004 and October 2015. We assessed comorbidities and complications, and performed univariate analysis to evaluate factors associated with inpatient mortality. Included were 321 hospital encounters in 294 patients. Fifty-one patients underwent 54 MV surgeries, 213 patients underwent 224 aortic/AV surgeries, and 43 patients underwent both MV and aortic/AV surgery in the same encounter. Postoperative complications were common for all surgeries (46.3% for MV procedures and 45.5% for aortic/AV procedures). Overall in-hospital mortality was 2.2% (3.7% for MV procedures, 1.8% for AV/aortic procedures, and 2.3% in the combined MV and aortic/AV procedure group). Aortic dissection or rupture was reported in 3.4%, with no in-hospital mortalities. Death after MV as well as after aortic/AV surgery was associated with younger age. Postoperative complications are common in pediatric and young adult patients with MFS after intervention on the MV, AV, and TA, although mortality is relatively low.

Abstract
This article is the latest in an EJCTS series entitled 'The Great Debates'. We have chosen the topic of aortic valve (AoV) surgery in children, with a focus on infants and neonates. The topic was selected due to the significant challenges that AoV problems in the young may present to the surgical team. There are many areas of active controversy, despite the vast accumulated world experience. We have tried to incorporate many of these issues in the questions posed, not claiming to be all-inclusive. The individuals invited to this debate are experts in paediatric valve surgery, with broad and successful clinical experiences on multiple continents. We hope that the facts and opinions presented in this debate will generate interest and discussion and perhaps prove useful in decision-making for future complex valve cases.

Abstract
Background In patients after aortic valve surgery, the quality of life is hypothesized to be influenced by the type of the valve procedure. A cross-sectional study on the postoperative quality of life was carried out in patients after aortic valve-sparing surgery (with regards to the age of the patient), Ross procedure and mechanical aortic valve replacement. Methods Quality of life was studied in 139 patients after aortic valve surgery divided into four study groups (Y – aortic valve-sparing procedure at the age below 50 years, mean age 36.2 years; O – aortic valve-sparing procedure at the age 50 years and over, mean age 59.2 years; R – Ross procedure, mean age 37.8 years and M – mechanical aortic valve replacement at the age below 50 years, mean age 39.2 years). SF-36 Short Form and valve-specific questionnaires were mailed to the patients after 6 months or later following surgery (median 26.9 months). Results In SF-36, the younger aortic valve repair patients and the Ross patients scored significantly better in 4 of 4 physical subscales and in 2 of 4 mental subscales than the older aortic valve repair and mechanical valve replacement patients. In the valve-specific questionnaire; however, all 3 groups free of anticoagulation (Y, O, and R) displayed greater freedom from negative valve-related concerns. Conclusions Postoperative quality of life is influenced by the type of aortic valve procedure and is negatively linked with mechanical prosthesis implantation and long-term anticoagulation. Aortic valve-sparing strategy should be considered in cases with suitable valve morphology due to favorable clinical results and beneficial impact on the long-term quality of life.

Abstract
In this paper, performance of aortic heart valve prosthesis in different geometries of the aortic root is investigated experimentally. The objective of this investigation is to establish a set of parameters, which are associated with abnormal flow patterns due to the flow through a prosthetic heart valve implanted in the patients that had certain types of valve diseases prior to the valve replacement. Specific valve diseases were classified into two clinical categories and were correlated with the corresponding changes in aortic root geometry while keeping the aortic base diameter fixed. These categories correspond to aortic valve stenosis and aortic valve insufficiency. The control case that corresponds to the aortic root of a patient without valve disease was used as a reference. Experiments were performed at test conditions corresponding to 70 beats/min, 5.5 L/min target cardiac output, and a mean aortic pressure of 100 mmHg. By varying the aortic root geometry, while keeping the diameter of the orifice constant, it was possible to investigate corresponding changes in the levels of Reynolds shear stress and establish the possibility of platelet activation and, as a result of that, the formation of blood clots.
