Abstract
OBJECTIVES Hepatic damage in Fontan circulation setting is well known. Mainly represented by fibrosis, it is still poorly understood. Transient hepatic elastography (Fibro-Scan) is a useful tool to test liver stiffness and is commonly used in the evaluation of liver fibrosis. Unfortunately, the increase of inferior vena cava pressure consequent to total cavopulmonary connection can probably interfere with Fibro-Scan evaluation altering the result evaluation with the conventional scale. To verify this hypothesis and to quantify the impact of venous pressure on Fibro-Scan results, we checked perioperative liver stiffness changes in patients undergoing total cavopulmonary connection. METHODS A prospective observational study was carried out on 9 patients undergoing extracardiac total cavopulmonary connection. Mean age at operation was 4.3 ± 0.6 years, and mean weight 14 ± 2.4 kg. Hepatic stiffness was analysed with Fibro-Scan evaluation immediately before and 4 months after surgery. Results were matched with several perioperative data: pulmonary pressures, conduit size, fenestration, hepatic enzymes and coagulation setting. RESULTS Preoperative hepatic stiffness was 6.2 ± 1.5 kPa, with a significant increase to 11.2 ± 4 kPa at a mean follow-up of 4 months (P < 0.01). Mean alanine aminotransferase was 16.9 ± 8.3 mg/dl preoperatively and 16.3 ± 8.7 mg/dl at discharge. Both values showed a significant correlation with liver stiffness raise, their Pearson Correlation Indexes being 0.8 and 0.7, respectively (P < 0.01). Mean aspartate aminotransferase/alanine aminotransferase ratio at discharge was 1.7 ± 0.5 and showed a significant negative correlation with liver stiffness raise, its Pearson Correlation Index being -0.7 (P < 0.01). CONCLUSIONS Liver stiffness increases rapidly after total cavopulmonary connection and perioperative variations in some liver enzymes appear to correlate with this change. Since a true anatomical damage is known to develop gradually with Fontan circulation, early liver stiffness raise is likely due to parenchymal congestion only. Fibro-Scan can easily recognize and assess the entity of such a change. For these reasons, this diagnostic tool must be considered useful only to monitor liver stiffness changes and evolution with time, but a conventional evaluation of results, like in other acquired hepatic fibrosis, can be misleading.

Abstract
OBJECTIVE Children undergoing Ross operation were expected to have longer autograft, but shorter homograft durability compared with adults. In order to define the outcome in the second decade after Ross operation in children, a nationwide review of 23 years of experience was undertaken. METHODS 305 children underwent Ross operation in 11 paediatric units between 1990 and 2012. Age at surgery was 9.4±5.7 years, indication aortic stenosis in 103 patients, regurgitation in 109 and mixed lesion in 93. 116 (38%) patients had prior procedures. Root replacement was performed in 201 patients, inclusion cylinder in 14, subcoronary grafting in 17 and Ross-Konno in 73. RESULTS There were 10 (3.3%) hospital and 12 late deaths (median follow-up 8.7 years). Survival was 93±2% and 89±3% and freedom from any reoperation was 76±3% and 67±6% at 10 and 15 years. 34 children had autograft 37 reoperations (25 replacement, 12 repair): three required transplantation after reoperation. Freedom from autograft reoperation was 86±3% and 75±6% at 10 and 15 years. 32 children had right heart redo procedures, and only 25 (78%) conduit replacements (15-year freedom from replacement, 89±4%). Prior operation (p=0.031), subcoronary implant (p=0.025) and concomitant surgical procedure (p=0.004) were risk factors for left heart reoperation, while infant age (p=0.015) was for right heart. The majority (87%) of late survivors were in NYHA class I, 68% free from medication and six women had pregnancies. CONCLUSIONS Despite low hospital risk and satisfactory late survival, paediatric Ross operation bears substantial valve-related morbidity in the first two decades. Contrary to expectation, autograft reoperation is more common than homograft.

Abstract
Pulmonary artery banding is a simple palliative surgical procedure for congenital heart defects with left-to-right shunt or complete mixing and pulmonary over-circulation. Even though indication for pulmonary artery banding has been sensibly reduced, since early reparative surgery has been proved superior to palliation and a staged approach, an increasing support for pulmonary banding has been raised in the last two decades by new indications such as left ventricular retraining, in the late arterial switch operation for complete transposition of the great arteries or before the double-switch operation in congenitally corrected transposition. Along with the increasing interest raised by the new indications and the consequently more diffuse use of banding, debanding has become an important surgical issue. Debanding is usually performed several months after palliation along with the repair of the cardiac malformations; otherwise, it can be done progressively or partially to further delay surgery and let the patient grow. Occasionally, after pulmonary artery banding, a spontaneous resolution of the underlying cardiac malformation can occur; however, a debanding procedure is in any case necessary.

Abstract
Pulmonary artery banding (PAB) is a simple surgical technique to reduce pulmonary overcirculation in some congenital heart disease. In the beginning, when the use of cardiopulmonary bypass was affected by many deleterious effects, this technique played a fundamental role in the treatment of patients with congenital heart defects and an intracardiac left-to-right shunt. The use of PAB has decreased during the last two decades, due to the increasing popularity of early complete intracardiac repair, which results have shown to be superior to staged repair, even in low body weight patients. Moreover, several authors have emphasized the negative effects of PAB such as pulmonary arterial branch distortion, abnormal right ventricular hypertrophy, pulmonary valve insufficiency, sub-aortic obstruction and decreased ventricular compliance in patients with univentricular heart. For all these reasons, this procedure has been placed in the dark corner of surgery, representing, between 2002 and 2005, ∼2% of the total amount of cardiac surgery procedures. In a more recent era, PAB has been performed in instances other than classic univentricular heart, as palliation in small infants with cardiac defects with a left-to-right shunt and pulmonary overcirculation, thus gaining some time prior to a planned staged repair. Recently, the role of PAB is becoming more important in selected subsets of congenital cardiac defects: L-transposition of the great arteries, D-transposition of the great arteries, hypoplastic left heart syndrome, moderately hypoplastic left ventricle (congenitally corrected transposition of the great arteries). This renewed interest in the banding procedure is spurring all surgeons and cardiologists to find new solutions for an easier banding procedure while making debanding less traumatic.

Abstract
OBJECTIVE Repair of partial anomalous pulmonary venous connection to superior vena cava using an internal patch has been described as a potential cause of obstruction at the systemic or pulmonary vein level and of sinus node dysfunction. Our experience with this operation was reviewed. METHODS From 1991 to 2011, 59 patients with a diagnosis of partial anomalous pulmonary venous connection to superior vena cava underwent surgical repair with intracardiac patch rerouting alone (45 patients) or with associated superior vena cava patch enlargement (14 patients). Follow-up evaluation was performed, including electrocardiogram, echocardiogram, electrocardiogram Holter monitor recording, and exercise stress test. RESULTS There were no early or late deaths and no reoperations at a mean follow-up of 46 ± 45 months. All patients were asymptomatic in New York Heart Association class I. Echocardiographic evaluation excluded any obstruction at the pulmonary or systemic vein level. At follow-up, 55 patients (93%) presented sinus rhythm and were free from antiarrhythmic medications, 2 patients (3%) presented atrial fibrillation, 1 patient (2%) presented atrial fibrillation and asymptomatic sinus node dysfunction, and 1 patient (2%) presented ectopic atrial rhythm. Electrocardiogram Holter recording demonstrated sinus node dysfunction in 6 of 34 patients (18%). Exercise stress test showed chronotropic incompetence in 8 of 27 patients (30%): All except 1 patient presented sinus rhythm at basal electrocardiogram, and only 4 patients had some evidence of sinus node dysfunction on electrocardiogram Holter recording. CONCLUSIONS Intracardiac repair of partial anomalous pulmonary venous connection can be performed with good results at medium-term follow-up. The rate of sinus node dysfunction or other arrhythmias and obstruction at pulmonary or systemic vein level is comparable to other techniques. Exercise stress test evaluation is the best way to detect asymptomatic sinus node dysfunction.

Abstract
Primary cardiac tumours are relatively rare in the paediatric population, and they may occur with different signs and symptoms in foetal or post-natal life. The clinical manifestations of cardiac tumours in foetal life may include arrhythmias, congestive heart failure and hydrops. In post-natal life, cardiac tumours may cause cyanosis, respiratory distress, myocardial dysfunction, valvular insufficiency, arrhythmias, inflow or outflow tract obstructions and sudden death. Surgical treatment is essential when symptoms are present, while the role of medical therapy can merely be palliative. Results are various and related to the patients' and tumour characteristics. Primary benign heart tumours mainly have a good prognosis, while malignant neoplasms usually have a poor prognosis; in both cases, however, a strict follow-up is always mandatory in order to detect the recurrence of cardiac neoplasms after surgery.

Abstract
A 45-year-old lady with dyspnea and occasional precordial chest pain was diagnosed with a huge sinus venosus atrial septal defect and partial anomalous pulmonary venous return. Preoperative coronary angiography disclosed severe main stem stenosis, considered secondary to compression by the dilated pulmonary trunk. Atrial septal defect closure and pulmonary artery reduction plasty were performed. The left main coronary artery appeared completely patent. The postoperative course was uneventful, and the patient was asymptomatic on follow-up.

Abstract
BACKGROUND Currently there is no evidence to prefer an endocardial or epicardial approach for pacing in pediatric patients. This analysis was aimed at defining the complications of pacemaker implantation in a pediatric population with atrioventricular block according to a strategy of choosing an epicardial system for patients <10 kg and an endocardial system for patients >10 kg. METHODS This is a retrospective study performed on 27 patients, with and without congenital heart disease, implanted with a permanent pacemaker because of idiopathic or acquired atrioventricular block at our Pediatric Cardiology and Cardiac Surgery Unit of S. Orsola-Malpighi Hospital in Bologna (Italy) between 1981 and 2010. Patients were divided into two groups: 70% of the population (group A) was implanted with an epicardial system, 30% (group B) with an endocardial system. RESULTS After a mean follow-up of 14 years (17 ± 8 years for group A, 7 ± 5 years for group B), the most frequent complications were lead failure (44%) and infection (18%). Both were more common in the epicardial system group: lead failure rate 53% in group A vs 25% in group B (p=0.0001); infection rate 26% in group A vs 0% in group B (p=0.0001); rate of system revision or implantation of a new electrode 42% in group A vs 12% in group B (p=0.0001). CONCLUSIONS The present study demonstrates a high complication rate in patients undergoing an epicardial pacing system implantation. However, in patients <10 kg the epicardial system allows subclavian venous access protection for endocardial system implantation after somatic growth, avoiding high-risk procedures of system revision or lead extraction and subclavian vein occlusion in the long term.

Abstract
BACKGROUND AND AIM OF THE STUDY Decellularized xenogeneic pulmonary valves have been introduced for right ventricular outflow tract (RVOT) reconstruction in congenital heart disease. In the present study, the intermediate-term results from three institutions were analyzed. METHODS Between January 2006 and September 2008, a total of 61 patients (median age 7 years; range: 9 days to 50 years; median body weight 21 kg; range: 1.9-140 kg) underwent RVOT reconstruction with either the Matrix P (n = 9) or Matrix P Plus (n = 52) tissue-engineered conduit. Eighteen patients underwent surgery in infancy, and 31 patients had previously undergone one or more RVOT interventions or operations. RESULTS The valve sizes ranged from 11 to 27mm. Five patients died during the hospital stay or within three months, from non-valve-related causes; hence, the early mortality was 8.2%. No deaths occurred during the follow up period. Reoperation due to valve failure became necessary in four patients; three patients underwent RVOT interventions due to distal anastomotic stenosis, and six reinterventions were performed distal to the valve due to hypoplastic branch pulmonary arteries. Patients with valve implantation during infancy showed a composite freedom from valve-related reoperation, catheter intervention or valve dysfunction (defined as dP(max) > 40 mmHg) of 87% at one and three years postoperatively. Both, computed tomography and magnetic resonance imaging studies demonstrated normal structural features, with no evidence of calcification. CONCLUSION The Matrix P/Matrix Plus conduit represents a viable alternative for RVOT reconstruction in patients with congenital heart disease. The intermediate-term performance of the conduits was favorable compared to that of other currently available implants.

Abstract
Background. Mitral valve replacement can be very difficult to obtain in infants because the valve annulus diameter can be smaller than the available prosthesis. Case Report. We describe the case of a 2-month-old female weighing 3.5 kg affected by mitral valve dysplasia leading to severe valve stenosis. Despite full medication, the clinical conditions were critical and surgery was undertaken. The mitral valve was unsuitable for repair and the orifice of mitral anulus was 12 mm, too small for a mechanical prosthesis. Therefore, a Ross-Kabbani operation was undertaken, replacing the mitral valve with the pulmonary autograft and reconstructing the right ventricular outflow tract with an etherograft. Results. The postoperative course was uneventful and the clinical conditions are good at 4-month follow-up.
Conclusion. The Ross-Kabbani operation can be an interesting alternative to mitral valve replacement in infants when valve repair is not achievable and there is little space for an intra-annular mechanical prosthesis implant.

Abstract
An 11-month-old infant, moderately cyanotic, with diagnosis of tetralogy of Fallot underwent corrective surgery. At echocardiographic evaluation, a subatretic right ventricular outflow tract without aortopulmonary collateral arteries, confluent pulmonary arteries and normal coronary pattern were evidenced. During operation, an undiagnosed large coronary-to-pulmonary artery fistula was disclosed. Because of the large variety of aortopulmonary collateral arteries that can be associated with this pathology, further imaging study is mandatory when oxygen saturation does not match the right ventricular outflow tract obstruction severity.

Abstract
Aortic coarctation without associated intracardiac lesions, with or without posterior arch hypoplasia referred as simple coarctation, is safely and effectively repaired via left posterolateral thoracotomy, whereas median sternotomy and cardiopulmonary bypass are necessary for aortic arch reconstruction in case of complete aortic arch hypoplasia, or coarctation with associated cardiac lesions. There is a wide variety of techniques currently proposed to repair neonatal coarctation, all reported associated with very low operative mortality, nevertheless which one would be the best technique in terms of minimal rate of residual or recurrent obstruction or late complications is still under debate.

Abstract
Surgical repair of the aortic arch is entailed in the neonatal period of patients with: hypoplastic left heart syndrome, interrupted aortic arch, hypoplastic aortic arch and complex aortic coarctation. Aortic arch surgery requires a period of circulatory arrest and deep hypothermia. Cerebral selective perfusion has recently been introduced as an alternative to circulatory arrest with the aim of reducing mortality and neurological complications. Moreover, the arch reconstruction phase can be safely performed under moderate hypothermia and with cerebral and myocardial perfusion (on beating heart), thus, completely avoiding cerebral ischemia and completely avoiding or drastically reducing myocardial ischemia.

Abstract
Until the recent availability of percutaneous devices, the role of the septal defect occluder was played by surgeons. In this paper the pros and cons of the two techniques in the approach to the atrial and ventricular septal defects are analyzed. Although the reported results are rather interesting, it seems clear that one of the crucial aspects to guarantee good results is the selection of patients for the transcatheter approach. Surgery is not confined by the constraints of defect anatomy, and good results may be achieved without regard to patient selection or an otherwise unfavorable anatomy of the defect. Up to now, the follow-up of transcatheter closure has been relatively short and cannot be compared with that of surgery. Therefore, caution should be exercised when proposing the transcatheter approach to septal defects as the true alternative to conventional surgery.

Moderately hypothermic cardiopulmonary bypass and low-flow antegrade selective cerebral perfusion for neonatal aortic arch surgery. Ann Thorac Surg 2006; 82:2233-9. [PMID: 17126140 DOI: 10.1016/j.athoracsur.2006.06.042] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2006] [Revised: 06/15/2006] [Accepted: 06/15/2006] [Indexed: 10/23/2022]
Abstract
BACKGROUND Although deep hypothermic circulatory arrest has been extensively used in neonates for aortic arch surgery, the brain and other organs might be adversely affected by prolonged ischemia and deep hypothermia. METHODS Between December 1997 and January 2005, 70 consecutive neonates underwent Norwood stage I procedure for hypoplastic left heart syndrome (group A, n = 30), or aortic arch repair for interruption or coarctation with arch hypoplasia (group B, n = 40), with antegrade selective cerebral perfusion (ASCP). Mean weights were 3.0 +/- 0.2 kg and 2.8 +/- 0.07 kg, and mean ages were 10 +/- 3.5 days and 14 +/- 10.6 days in groups A and B, respectively. Only 2 patients were older than 30 days. Core body temperature was lowered to 25 degrees C, and mean pump flow during ASCP was initiated at 10 to 20 mL/(kg x min) and adjusted to guarantee a radial/temporal artery pressure of 30 to 40 mm Hg and venous oxygen saturation of more than 70%. Hematocrit was maintained at 30%. RESULTS Early mortality was 17% (group A, 23%; group B, 12.5%; p = 0.19). Six late deaths occurred (3 in each group), and at 36 months, Kaplan-Meier overall survival was 64% +/- 9.2% in group A and 85% +/- 5.7% in group B. One patient had postoperative seizures. Age, weight, sex, prematurity, group A, and ASCP duration did not influence early mortality. CONCLUSIONS Antegrade selective cerebral perfusion is a safe and effective procedure and might improve outcome of neonatal aortic arch surgery, minimizing neurologic impact without the need for deep hypothermia.

Abstract
Sternal re-entry adds supplementary risk to cardiac re-operations and it may represent the most important factor in the entire hazard estimation. A new anti-adhesive substance, based on a polyethylene glycol material, has been proposed to solve this problem. Results and surgical observations at chest re-entry in five patients treated with this synthetic polymer are herein discussed.
