Congenital: Aortic Valve
Valve-sparing root replacement after the Ross procedure
The Ross procedure is a preferred treatment for infants and children with aortic valve disease. Progressive neoaortic root dilation and neoaortic insufficiency can occur after the Ross procedure, and because of the young age of these patients, valve-sparing aortic root replacement procedures have advantages compared with the Bentall procedure. The aim of this study is to describe our experience with different techniques of aortic valve-sparing root replacement in this unique cohort of patients.Ross procedure in neonates and infants: A valuable operation with defined limits
The Ross procedure is an important tool that offers autologous tissue repair for severe left ventricular outflow tract (LVOT) pathology. Previous reports show that risk of mortality is highest among neonates and infants. We analyzed our institutional experience within this patient cohort to identify factors that most affect clinical outcome.Long-term outcomes of primary aortic valve repair for isolated congenital aortic stenosis in children
We aimed to assess the long-term outcomes of children with isolated congenital aortic stenosis who underwent primary aortic valve repair.Outcomes of aortic valve repair in children resulting in bicuspid anatomy: Is there a need for tricuspidization?
We aimed to assess outcomes after aortic valve repair leading to bicuspid valve anatomy in children.The Ross/Ross-Konno procedure in infancy is a safe and durable solution for aortic stenosis
The objective of this study was to characterize early and midterm outcomes after the Ross/Ross-Konno procedure performed in infancy for severe aortic valve disease.Ross procedure or complex aortic valve repair using pericardium in children: A real dilemma
Difficult to repair aortic valve lesions, requiring the use of a valve substitute, remain controversial in the face of the Ross procedure, despite undeniable technical advances. This study was undertaken to compare midterm outcomes of children treated using the Ross procedure or aortic valvuloplasty for complex aortic valve lesions.Aortic valve repair in children without use of a patch
We aimed to assess the long-term outcomes of children in whom the aortic valve could be repaired without the use of patch material. We hypothesized that if the aortic valve is of sufficiently good quality to perform repair without patches, a durable repair could be achieved.Congenital aortic and truncal valve reconstruction using the Ozaki technique: Short-term clinical results
Aortic valve reconstruction (AVRec) with neocuspidization or the Ozaki procedure with complete cusp replacement for aortic valve disease has excellent mid-term results in adults. Limited results of AVRec in pediatric patients have been reported. We report our early outcomes of the Ozaki procedure for congenital aortic and truncal valve disease.The utility of aortic valve leaflet reconstruction techniques in children and young adults
The treatment of aortic valve disease in children and adolescents requires an individualized approach to provide a long-term solution with optimal hemodynamic profile. The role of aortic leaflet reconstruction techniques is evolving.Surgical outcomes for anomalous left coronary artery from the pulmonary artery: Influence of late presentation
Although surgical outcomes for anomalous left coronary artery from the pulmonary artery (ALCAPA) are excellent in the modern era with the coronary reimplantantion technique, mortality remains high in Chinese population. This study was undertaken to review the surgical management for ALCAPA in our center and assess the midterm outcomes.Surgical palliation or primary transplantation for aortic valve atresia
The study objective was to describe the surgical pathway progression through adolescence of an inception cohort of neonates with aortic valve atresia managed initially with surgical palliation or primary transplantation, comparing survival and self-reported health-related quality of life.Maladaptive remodeling of pulmonary artery root autografts after Ross procedure: A proteomic study
Pulmonary autograft root dilatation is the major long-term complication after Ross procedure and the leading cause for reoperation. However, the mechanisms underlying dilatation remain to be elucidated. This study analyzed the proteomic changes seen in the dilated pulmonary autograft compared with normal pulmonary artery and aorta tissues.Ventricular interactions and electromechanical dyssynchrony after Ross and Ross-Konno operations
Ross and Ross-Konno operations are associated with the inherent risk of residual ventricular septal dysfunction and injury to the conduction system. However, comprehensive biventricular functional outcomes on magnetic resonance imaging after Ross and Ross-Konno procedures are unknown. The purpose of this study was to evaluate and compare the degree of electrical and mechanical dyssynchrony using cardiac magnetic resonance imaging in patients late after Ross and Ross-Konno operations.Self-reported functional health status following interrupted aortic arch repair: A Congenital Heart Surgeons' Society Study
Improved survival after congenital heart surgery has led to interest in functional health status. We sought to identify factors associated with self-reported functional health status in adolescents and young adults with repaired interrupted aortic arch.Valve-sparing aortic root replacement in children: Outcomes from 100 consecutive cases
Valve-sparing root replacement is an attractive alternative to composite mechanical or biologic prostheses for aortic root aneurysms in children. Data on outcomes in pediatric patients are limited. We present our institutional experience with 100 consecutive pediatric valve-sparing aortic root procedures.Selection of prosthetic aortic valve and root replacement in patients younger than age 30 years
Long-term outcomes of prosthetic aortic valve/root replacement in patients aged 30 years or younger are not well understood. We report our single institutional experience in this young cohort.Aortic stenosis of the neonate: A single-center experience
Because data for neonates are limited, optimal management of critical aortic stenosis remains controversial (balloon valvotomy [BV] or open valvoplasty [OV]). In a center with balanced experience in both methods, we hypothesized that OV can provide a better individualized approach than blunt BV and better serve long-term outcomes.Outcomes after mechanical aortic valve replacement in children and young adults with congenital heart disease
There are little recent data on the outcomes of mechanical aortic valve replacement (AVR) in children and young adults with congenital aortic valve disease. We sought to review the survival and associated thromboembolic or bleeding complications after mechanical AVR at a single center.Repair of a quadricuspid truncal valve by tricuspidization and reconstruction of right ventricular outflow tract with the excised truncal cusp
Quadricuspid truncal valves are susceptible to regurgitation, and tricuspid configuration is considered more durable after repairing the truncal valve. We report a new method by excising the excessive truncal cuspid to reconstruct a new competent aortic valve.Outcome after aortic valve replacement in children: A systematic review and meta-analysis
Despite an increasing interest in pediatric aortic valve repair, aortic valve replacement in children may be unavoidable. The evidence on outcome after pediatric aortic valve replacement is limited and usually reported in small case series. This systematic review and meta-analysis aims to provide an overview of reported outcome of pediatric patients after aortic valve replacement.A composite semiresorbable armoured scaffold stabilizes pulmonary autograft after the Ross operation: Mr Ross's dream fulfilled
Use of resorbable external reinforcement of the pulmonary autograft during the Ross operation has been suggested, but the differential regional potential for dilation of the aorta, mainly regarding the neo-root and the neo-Valsalva sinuses, represents an unresolved issue. Auxetic materials could be useful in preventing dilation given their favorable mechanical properties. We designed a composite semiresorbable armoured bioprosthesis constituted by polydioxanone and expanded polytetrafluoroethylene and evaluated its effectiveness as a pulmonary autograft reinforcement device in an animal model of the Ross procedure.
