Background: St. Thomas (ST) and Del Nido (DN) cardioplegic solutions are widely used for myocardial protection during cardiac surgery. In 2016, our university hospital shifted from modified St. Thomas to Del Nido solution for both adult and pediatric cardiac surgery. This retrospective study was conducted to compare ST and DN solutions regarding surgical workflow and clinical outcome in pediatric and adult patients undergoing cardiac surgery. Methods: We reviewed 220 patients who underwent cardiac surgery requiring cardioplegic arrest. Patients were categorized in 2 groups: ST (n = 110) and DN (n = 110). Each group included 60 pediatric and 50 adult patients. Demographic, intraoperative, and postoperative variables were collected. Results: In pediatric patients, no significant difference was found between the 2 groups regarding clamping time, bypass time, need for defibrillation, inotropic score, postoperative ejection fraction (EF), period of mechanical ventilation, intensive care unit stay, or postoperative arrhythmias. One patient in the ST group required mechanical support by extracorporeal membrane oxygenation. We had 5 cases of pediatric mortality (3 in DN and 2 in ST, P = .64). In adult patients, significantly fewer patients in the DN group needed defibrillation than in the ST group. No significant difference was found regarding clamping time, inotropic score, or intraaortic balloon pump use. Mortality in adult patients was 6 cases (4 in ST group and 2 in DN group). Conclusion: DN cardioplegia solution is as safe as ST solution in pediatric and adult cardiac surgery. It has comparable results of myocardial protection and clinical outcome, with superiority regarding uninterrupted surgery and lower rate of defibrillation.
Background Pericardial patches are often used for repair of congenital cardiac defects. The aim of this study was to describe our initial experience with the use of equine pericardium and its safety and advantages and disadvantages compared to bovine pericardium. Methods We designed a retrospective cohort study of 111 patients who were surgically treated for congenital heart disease between 2017 and 2020. Equine pericardium was used in 58 patients and bovine pericardium was used in 53 patients. Recorded variables included demographic data, preoperative cardiac pathology, site of patch insertion, morbidity and mortality. Results The overall survival rate was 94.5% and no deaths were related to patch insertion. None of our patients were reoperated on for patch related complications. Postoperative transcatheter intervention was needed in 2 patients (1.8%): one for dilatation of aortic arch stenosis after repair of hypoplastic left heart syndrome with equine pericardium and one for dilatation of pulmonary artery branches after repair of tetralogy of Fallot using bovine pericardium. Conclusions Equine pericardium is a safe patch material for reconstruction in congenital heart surgery. It may be preferable to bovine pericardium in cases requiring a complex shape or a pliable patch as in in arch reconstruction or for valve reconstruction.
Objective Many studies still dispute the identification of independent risk factors that influence outcome after neonatal cardiac surgery. We present our study to announce the contemporary outcomes and risk profile of neonatal cardiac surgery at our institute. Methods We designed a retrospective study of neonatal patients who underwent surgery for congenital heart diseases between June 2011 and April 2020. Demographic, operative, and postoperative data were collected from medical records and surgical databases. The primary outcome was the operative mortality (in-hospital death) and secondary outcomes included hospital length of stay, intensive care unit stay, duration of mechanical ventilation. Results In total, 1155 cardiac surgeries in children were identified; of these, 136 (11.8%) were performed in neonates. Arterial switch operations (48 cases) were the most frequent procedures. Postoperatively, 11 (8.1%) patients required extracorporeal membrane oxygenation, and 4 (2.9%) patients had complete heart block. Postoperative in-hospital mortality was 11%. The median postoperative duration of mechanical ventilation, intensive care unit stay, and hospital length of stay were 6, 18, and 24 days, respectively. Conclusion The early outcomes of neonatal cardiac surgery are encouraging. The requirement of postoperative extracorporeal membrane oxygenation support, postoperative intracranial hemorrhage, and acute kidney were identified as independent risk factors of mortality following surgery for congenital heart defects in neonates.
