Prompt diagnosis and surgical repair are important for a favorable outcome. Overall, operative mortality has been cited to be between 3% and 8.3%. Associated congenital coronary arterial anomalies, residual severe aortic stenosis, poor left ventricular function, and rupture of an infected suture line have been the reported causes of death. Despite early surgical intervention, an incidence of 16% to 60% postoperative residual aortic regurgitation of varying severity has been reported. The requirement of further repair or replacement of the aortic valve ranges from 0% to 50%. We submit that an increased appreciation of these details relative to the tunnels will contribute to improved surgical management.Several techniques designed to improve long-term results after repair of tetralogy of Fallot are described. We have recently embarked on a program focused on preserving the native pulmonary valve. Here, combined techniques are described in detail, including intraoperative pulmonary valve balloon dilatation, pulmonary valve reconstruction by delamination and resuspension of the leaflets, and pulmonary valve annulus augmentation. As with any other complex congenital heart disease, senior surgeons should select teaching cases, starting from the less severe side of the spectrum.We report a case of Bentall and redo-Konno operation. A 39-year-old male with surgical history of Konno operation presented with hemolytic anemia and heart failure. Further evaluations revealed aortic paraprosthetic leak with moderate regurgitation, moderate biventricular outflow tract obstruction, and aortic root aneurysm. During the operation, the old Konno septoplasty patch with organized thrombus and the severely calcified right ventricular patch were replaced, and the aortic root was replaced with a larger mechanical valve in a Valsalva graft. Postoperative images showed appropriately reconstructed biventricular outflow tracts. The Bentall operation with redo-Konno was an excellent option in this situation.<br /><br /> To assess changes in patterns of practice and outcomes over time, we reviewed all patients who underwent heart transplantation (HTx) at our institution and compared two consecutive eras with significantly different immunosuppressive protocols (cohort 1 [80 HTx, June 1995-June 2006]; cohort 2 [108 HTx, July 2006-September 2018]).<br /><br /> Retrospective study of 180 patients undergoing 188 HTx (June 1995-September 2018; 176 first time HTx, 10 second HTx, and 2 third HTx). In 2006, we commenced pre-HTx desensitization for highly sensitized patients and started using tacrolimus as our primary postoperative immunosuppressive agent. The primary outcome was mortality. Survival was modeled by the Kaplan-Meier method. Univariable and multivariable Cox proportional hazard models were created to identify prognostic factors for survival.<br /><br /> Our 188 HTx included 18 neonates, 85 infants, 83 children, and 2 adults (&gt;18 years). Median age was 260.0 days (range 5 days-23.8 years). Median weight was 7.5 kg (range 2.2-113 kg). Patite the higher proportion of patients with elevated panel reactive antibody in the most recent era. This improvement was temporally associated with changes in our immunosuppressive strategy.<br /><br /> Repair of tetralogy of Fallot (TOF) with major aortopulmonary collateral arteries (MAPCAs) requires unifocalization of pulmonary circulation, intracardiac repair with the closure of the ventricular septal defect, and placement of a right ventricle (RV) to pulmonary artery (PA) conduit. The decision to perform complete repair is sometimes aided by an intraoperative flow study to estimate the total resistance of the reconstructed pulmonary circulation.<br /><br /> We reviewed patients who underwent unifocalization and PA reconstruction for TOF/MAPCAs to evaluate acute and mid-term outcomes after repair with and without flow studies and to characterize the relationship between PA pressure during the flow study and postrepair RV pressure.<br /><br /> Among 579 patients who underwent unifocalization and PA reconstruction for TOF/MAPCAs, 99 (17%) had an intraoperative flow study during one (n = 91) or more (n = 8) operations to determine the suitability for a complete repair. [https://www.selleckchem.com/products/pf-06700841.html PF-06700841 order] There was a reasonably good correlation between mean PA plity of single-stage complete repair.One in a hundred babies, or 1.3 million per year around the world, are born with congenital heart defects (CHD), of which over 70% will require medical or surgical treatment within their first year of life. In low- and middle-income countries, the majority does not receive the treatment they need or receive suboptimal care. Despite a higher pediatric cardiac surgical disease burden, low-income countries only have 0.07 pediatric cardiac surgeons per million pediatric population, compared to 9.51 per million in high-income countries. Here, we perform a stakeholder analysis of existing advocacy bodies within the field of pediatric global cardiac surgery and identify gaps and opportunities in advocating for cardiac care for children with CHD. We propose a framework to optimize civil society messaging in order to more effectively advocate domestically and internationally to hold national and international policy makers accountable for existing gaps and disparities in CHD care around the world.<br /><br /> Surgical repair of partial anomalous pulmonary venous connection (PAPVC) may disturb the electrical conduction in the atria. This study documents long-term outcomes, including the late occurrence of atrial tachyarrhythmia and bradyarrhythmia.<br /><br /> This retrospective study covers all PAPVC operations at Aarhus University Hospital between 1970 and 2010. Outcome measures were arrhythmias, sinus node disease, pacemaker implantation, pathway stenosis (pulmonary vein(s), intra-atrial pathway, and/or superior vena cava), and mortality. Data were collected from databases, surgical protocols, and hospital records until May 2018.<br /><br /> A total of 83 patients were included with a postoperative follow-up period up to 46 years. Average age at follow-up was 43 ± 21 years. During follow-up, new-onset atrial fibrillation or atrial flutter appeared in four patients (5%). Sinus node disease was present in nine patients (11%). A permanent pacemaker was implanted in seven patients (8%) at an average of 12.7 years after surgery. Pulmonary venous and/or superior vena cava obstruction was seen in five patients (6%).
