Abstract
OBJECTIVE The purpose of this study is to assess the mid-term outcomes of aortic root replacement after repair of CHDs. METHOD This is a single-institutional retrospective, cohort study with consecutive patients undergoing aortic root replacement after surgical repair of CHDs between 1999 and 2022. Operative indications included aortic root dilatation with/without aortic insufficiency, sinus of Valsalva rupture, or aortic dissection involving the root. RESULTS Forty-four patients (36 male and 8 female) were enrolled. Mean age at the root replacement was 36.6 ± 11.9 years. The most frequent primary diagnosis was congenital aortic stenosis (n = 10) and ventricular septal defect (n = 10). Mean time from the surgical repair to aortic root replacement was 26.6 ± 13.0 years. Operative indications were aortic root enlargement with or without aortic valve aetiology (n = 40), sinus of Valsalva rupture (n = 2), and aortic dissection (n = 2). Forty-two patients underwent valve-replacing aortic root replacement, and two patients underwent valve-sparing, with 40 concomitant procedures. The median follow-up was 3.5 (1.3-7.6) years. There were one early and five late mortalities and five cardiovascular-related reoperations. Actuarial survival at 5-10 years after root replacement was 81.0 ± 6.6%. The cumulative incidence of cardiovascular-related reoperation and aortic root or valve-related reoperation at 5 years after root replacement was 11.9% and 5.6%, respectively. CONCLUSION The early and mid-term outcomes of aortic root replacement for patients with a history of repair of CHDs were favourable in terms of survival and aortic root or valve-related reoperation.

Abstract
An incidental finding of right coronary artery compression, between the dilated aortic root and the sternum, was detected on follow-up cardiac catheterization after Fontan completion for tricuspid atresia with transposition of the great arteries. Although this 31-year-old man had no subjective symptoms, an exercise stress test and perfusion scan revealed ischemic changes in the inferior region. Valve-sparing aortic root replacement using the reimplantation technique proved to be an effective approach for this condition. The possibility of coronary artery compression associated with aortic root dilatation should be considered in patients with adult congenital heart disease.

Abstract
BACKGROUND Aortopathy is a well-known feature of conotruncal anomalies, but it remains unknown whether valve-sparing aortic root replacement, such as the David procedure, is feasible in young patients with severe aortic regurgitation. We assessed the aortic valve complex and aortic root morphology in patients with conotruncal anomalies using echocardiography. Furthermore, we evaluated the relevant factors associated with aortopathy in this population. METHODS A total of 172 adult patients with conotruncal anomalies were enrolled in this study. Dimensions of the aortic valve complex were measured at the level of the sinus of Valsalva (SV) and sinotubular junction (STJ). The geometric height (GH), effective height (EH), and coaptation length (CL) were also assessed to analyze the aortic valve complex in detail. RESULTS Sixteen of 172 patients were excluded due to poor imaging; 105 patients with tetralogy of Fallot, 24 with double outlet right ventricle, and 27 with transposition of the great arteries totaling 156 patients (32+/-11 years old) were included in the analysis. The patients were divided into four groups: Group 1 (98 patients) had no dilatation of SV or STJ; Group 2 (32 patients) had dilated SV and STJ; Group 3 (14 patients) had dilated SV; and Group 4 (12 patients) had dilated STJ. GH and EH in Group 2 were also highest among the four, whereas CL was not significantly shortened. Multivariate analysis revealed that male sex, age, and conduit repair were risk factors for aortopathy in this population. CONCLUSIONS Patients with dilated SV and STJ (Group 2) were the most common among the patients with aortopathy (Groups 2, 3, and 4). The aortic valve leaflets themselves were enlarged, and the poor coaptation of the valve tips was compensated in spite of aortic root dilatation, which plays an important role in preventing severe aortic regurgitation in this population. Overall, valve-sparing aortic valve replacement is more feasible in the young populations than we expected.

Abstract
OBJECTIVES Aortic root dilatation is frequently observed in patients with congenital heart defects (CHD), but has received little attention in terms of developing a best practice approach for treatment. In this study, we analysed our experience with aortic valve-sparing root replacement in patients following previous operations to repair CHD. METHODS In this study, we included 7 patients with a history of previous surgery for CHD who underwent aortic valve-sparing operations. The underlying initial defects were tetralogy of Fallot (n = 3), transposition of great arteries (n = 2), coarctation of the aorta (n = 1), and pulmonary atresia with ventricle septum defect (n = 1). The patients' age ranged from 20 to 40 years (mean age 31 ± 6 years). RESULTS David reimplantation was performed in 6 patients and a Yacoub remodelling procedure was performed in 1 patient. Four patients underwent simultaneous pulmonary valve replacement. The mean interval between the corrective procedure for CHD and the aortic valve-sparing surgery was 26 ± 3 years. There was no operative or late mortality. The patient with transposition of great arteries following an arterial switch operation was re-operated 25 months after the valve-sparing procedure due to severe aortic regurgitation. In all other patients, the aortic valve regurgitation was mild or negligible at the latest follow-up (mean 8.7 years, range 2.1-15.1 years). CONCLUSIONS Valve-sparing aortic root replacement resulted in good aortic valve function during the first decade of observation in 6 of 7 patients. This approach can offer a viable alternative to root replacement with mechanical or biological prostheses in selected patients following CHD repair.

Abstract
Introduction and importance Aortic regurgitation and aortic root dilatation are common features in adults with both repaired and unrepaired tetralogy of Fallot (TOF). Valve-sparing aortic root replacement (VSARR) is an effective repair for aortic regurgitation due to progressive aortic root dilatation with TOF after repair. However, the effectiveness of this technique for unrepaired patients has rarely been reported. Case presentation We reported a case of a 30-year-old man with cyanosis and exertional dyspnea. Echocardiography and computed tomography showed unrepaired TOF with significant aortic regurgitation and massively dilated aortic root. Aortic root replacement was mandatory. He underwent successful concomitant VSARR with TOF repair. At 6-month follow-up, he remains stable with trivial aortic regurgitation on echocardiogram. Clinical discussion In unrepaired TOF, the absence of sub-annular muscular rim and the unbalance of aortic sinuses make VSARR utmost challenging. If can be done successfully, VSARR preserves the native aortic valve and avoids lifelong anticoagulation therapy. Conclusion Concomitant VSARR with TOF repair can be safely and effectively applied for unrepaired patients presenting with progressive aortic root dilatation and significant aortic regurgitation. Survival of adults with unrepaired tetralogy of Fallot and progressive aortic root dilatation is not common. We presented a tetralogy of Fallot adult with significant aortic regurgitation and massively aortic root dilatation. Aortic root replacement was mandatory in this patient. Valve-sparing aortic root replacement (VSARR) has rarely been reported in unrepaired physiology. We successfully performed concomitant VSARR with Fallot repair.

Abstract
OBJECTIVES We report the mid-term outcomes of valve-sparing aortic root replacement (VSRR) in a cohort including patients with bicuspid aortic valve (BAV), connective tissue disorder (CTD), aortic dissection (AD), and congenital heart disease (CHD). Design. From 2005 to 2017, 174 patients underwent VSRR with the reimplantation technique. The mean age was 46 ± 14 years. The mean follow-up time was 4.8 ± 2.8 years. The indication for operation was aortic aneurysm for 127 (73%), aortic insufficiency (AI) for 38 (22%), and AD for 9 patients (5%). Preoperatively, 53 patients (31%) had ≥ moderate AI. BAV, CTD (Marfan or Loyes-Dietz), previous Ross procedure, or CHD was present in 57 (33%), 28 (16%), 7 (4%) and 12 patients (7%), respectively. Concomitant aortic valve repair was performed for 103 patients (59%). Results. Thirty-day mortality was zero. Four patients underwent aortic valve replacement (AVR) during follow-up. Kaplan-Meier estimates for survival, freedom from AVR, and freedom from ≥ moderate AI or reoperation were 96, 98, and 97% at 5 years. There was no difference in survival, freedom from AVR, or freedom from ≥ moderate AI or reoperation in patients with and without BAV, CTD, leaflet repair, or preoperative ≥ moderate AI. In Cox regression analysis, BAV, CTD, aortic valve repair, preoperative ≥ moderate AI, or aortic dimension were not risk factors for reoperation or valve dysfunction. Conclusions. Mid-term outcomes of VSRR for patients with diverse indications in terms of survival, reoperation rate, and valve dysfunction rate were excellent in a center with a limited annual volume of VSSR.

Abstract
Background Aortic dilatation may occur in some patients even after complete repair of tetralogy of Fallot (TOF). The progression rate of the aortic diameter is so slow, and the incidence of aortic dissection is so low that it is suspected that frequent imaging of the aorta may not be necessary. Case presentation We describe an asymptomatic 41-year-old man with hypertension in whom aortic dilatation was accidentally discovered 39 years after TOF repair. He underwent ambulatory follow-up without any difficulty for 21 years after the repair. Contrast-enhanced computed tomography revealed significant aortic dilatation (maximum diameter of 88 mm at the sinus of Valsalva), and echocardiography revealed severe aortic regurgitation, which seemed to progress during the last 18 years without any evaluation or follow-up. The Bentall procedure was successfully performed using a valved graft, under deep hypothermic circulatory arrest with antegrade cerebral perfusion, and his postoperative course was uneventful. Histopathological examination of ascending aorta specimens revealed severe cystic medial degeneration. Conclusions Keeping in mind that a patient with rapid progression of the aortic dilatation after TOF repair exist, periodic follow-up for evaluation of the aorta is essential in patients with TOF.

Abstract
Valve-sparing aortic root replacement is one of the effective repairs for aortic regurgitation resulting from progressive dilatation of the aortic root late after surgical correction of conotruncal anomaly. However, feasibility and effectiveness of this procedure are unknown for unrepaired physiology. A 32-year-old man presented with unrepaired tetralogy of Fallot (TOF) and moderate aortic regurgitation with severe left ventricular dysfunction. Valve-sparing aortic root replacement and TOF repair were simultaneously performed. Six months after the surgical procedure, aortic regurgitation remained trivial. Concomitant valve-sparing aortic root replacement with TOF repair can be feasible and effective for unrepaired TOF with aortic regurgitation.

Abstract
Today, more than two thirds of patients with congenital heart disease (CHD) are adults. Cardiac surgery plays an essential role in restoring and maintaining cardiac function, aside from evolving medical treatment and catheter-based interventions. The aim of the present publication was to describe the spectrum of operations performed on adults with CHD (ACHD) by reviewing current literature. Currently, surgery for ACHD is predominantly valve surgery, since valvular pathologies are often either a part of the basic heart defect or develop as sequelae of corrective or palliative surgery. Surgical techniques for valve repair, established in patients with acquired heart disease (non-ACHD), can often be transferred to ACHD. New valve substitutes may help to reduce the number of redo operations. Most of valve operations yield good results in terms of survival and quality of life, with the precondition that the ventricular function is preserved. Heart failure due to end-stage CHD is the most frequent cause of mortality in ACHD. However, surgical treatment by means of mechanical circulatory support (MCS) is still uncommon and the mortality exceeds the one following other operations in ACHD. Currently, different devices are used and new technical developments are in progress. However, there still is no ideal assist device available. Therefore, heart transplantation remains the only valid option for end-stage CHD. Despite higher early mortality following heart transplantation in ACHD compared to non-ACHD, the long-term survival compares favorably to non-ACHD. There is room for improvement by refining the indications, the time of listing, and the perioperative care of ACHD transplant patients. Sudden death is the second most frequent cause of mortality in ACHD. Ventricular tachycardia is the most frequent cause of sudden death followed by coronary artery anomaly. Due to the increasing awareness of physicians and the improved imaging techniques, coronary artery anomalies are coming more into the focus of cardiac surgeons. However, the reported experience is limited and it is currently difficult to provide a standardized and generally applicable recommendation for the indication and the adequate surgical technique. With the increasing age and complexity of ACHD, treatment of rhythm disturbances by surgical ablation, pacemaker or implantable cardioverter defibrillator (ICD) implantation and resynchronisation gains importance. A risk score specifically designed for surgery in ACHD is among the newest developments in predicting the outcome of surgical treatment of ACHD. This evidence-based score, derived from and validated with data from the Society of Thoracic Surgeons Congenital Heart Surgery Database, enables comparison of risk-adjusted performance of the whole spectrum of procedures performed in ACHD and helps in understanding the differences in surgical outcomes. The score is thus a powerful tool for quality control and quality improvement. In conclusion, new developments in surgery for ACHD are currently made with regard to valve surgery, which comprises more than half of all operations in ACHD and in treatment of end-stage CHD, which still yields high mortality and morbidity.
