DHCA has been linked to adverse outcomes and neurologic complications. Selective cerebral perfusion (SCP) may be added to DHCA to prevent neurological complication. Air embolism and hyperperfusion injury may be encountered. The aim of this study was to evaluate the safety and efficacy of simple DHCA and to outline the early outcomes especially the neurological ones. Methods Twenty nine patients underwent surgical repair of congenital cardiac lesion with DHCA at a single institution from January 2010 to November 2015. DHCA was conducted with a target esophageal temperature of 18° and placement of an ice pack on the head. No selective perfusion was done. Demographic, operative and postoperative data were reviewed. Mortality, any neurological complications including seizers, coma, and stroke were recorded. Resul...

We describe the management and outcomes of this complication in both groups. Methods We retrospectively analyzed 16 patients (5 adults and 11 children) with diaphragmatic paralysis after cardiac surgery performed between 2008 and 2018. Clinical examination, chest radiography, and confirmation with fluoroscopy in selected cases were our modalities of diagnosis. All adults were managed conservatively, whereas plication was performed in all children. Results The incidence of diaphragmatic paralysis was 0.98% in pediatric patients and 0.43% in adults. The mean age was 2.33 ± 2.59 years in children and 53.2 ± 17.99 years in adults. All adults were symptomatic. All children showed difficulty in weaning from mechanical ventilation after cardiac surgery. The period of mechanical ventilation before ...

The main objective of this study was to evaluate the safety, efficacy, and outcome of cardiac catheterization performed in the early post-operative period following congenital heart surgery. All patients who underwent cardiac catheterization after congenital heart surgery during the same admission of cardiac surgery from November 2015 to May 2018 were included in the study. Results Thirty procedures were performed for 27 patients (20 interventional and 10 diagnostic). The median age of the patients was 15 months (15 days to 20 years), median weight was 8.2 kg (3.4 to 53 kg), and median time from surgery was 3 days (0–32 days). Eleven procedures were performed for 11 patients on extracorporeal membrane oxygenation (ECMO) support. The main indications for catheterization included the inability to w...

This study aimed to evaluate the safety and outcome of cardiac catheterization in patients undergoing ECMO after congenital cardiac surgery and determine predictors that influence successful weaning. This retrospective cohort study included pediatric patients who underwent cardiac catheterization while on ECMO after congenital heart surgery in two cardiac centers between November 2012 and February 2020. Predictors of successful weaning from ECMO were studied using univariate and multivariate logistic regression analyses. Of 123 patients on ECMO support after congenital cardiac surgery, 60 patients underwent 60 cardiac catheterizations (31 diagnostic and 29 interventional). Thirty-four (56.7%) and 22 patients (36.7%) underwent successful decannulation from ECMO support and survived after hospital discharge, respectively. Patients who underwent earlier catheterization (within 24 h of ECMO initiation) had more successful weaning from ECMO and survival compared to others. Patients who underwent an interventional procedure (interventional catheterization or redo cardiac surgery after cardiac catheterization) had better survival than those who underwent only diagnostic catheterization (P = 0.038). Shorter durations of ECMO was the most important predictor of successful weaning from ECMO. Early cardiac catheterization greatly impacts successful weaning from ECMO and survival. Patients with correctable lesions amenable either by catheterization or redo surgery are more likely to survive. Shorter durations of ECMO could have a significant influence on successful weaning from ECMO and survival.

Perioperative blood loss and rate of re-exploration are variable among centers and surgeons. Objective To present our experience of low rate of re-exploration based on adopting checklist for hemostasis and algorithm for management. Methods Retrospective analysis of medical records was conducted for 565 adult patients who underwent surgical treatment of congenital and acquired heart disease and were complicated by postoperative bleeding from Feb 2006 to May 2019. Demographics of patients, operative characteristics, perioperative risk factors, blood loss, requirements of blood transfusion, morbidity and mortality were recorded. Logistic regression was used to identify predictors of re-exploration and determinants of adverse outcome. Results Thirteen patients (1.14%) were reexplored for bleeding. An identifiable source of bleeding was found in 11 (84.6%) patients. Risk fa...

Materials and methods: This is a retrospective study with 51 consecutive patients who underwent BDG operation as a primary operation or a second stage prior to the definitive Fontan operation at King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia between 2010 and 2018. Patients were categorized into two groups based on their PBF prior to the operation: Patients who had SV physiology and increased PBF (seven patients) vs. patients with SV physiology and restricted PBF (44 patients). Results: The median age for the increased PBF group was 9.9 months [interquartile range (IQR): 2-16.9 months], and the median age for the restricted PBF group was 15.3 months (IQR: 6.7-42.6 months). Although the length of hospital ...

It first was introduced in the mid-1990s and aspired to bring together the “best of both worlds” – the excellent patency rates and survival benefits associated with the durable left internal mammary artery graft to the left anterior descending artery alongside the good patency rates of drug-eluting stents, which outlive saphenous vein grafts to non–left anterior descending vessels. Although in theory this is a very attractive revascularization strategy, several years later, only small randomized controlled trials comparing HCR with coronary artery bypass grafting has recently emerged in the medical literature, raising concerns regarding HCR’s role. In the current review, we discuss HCR’s rationale, the curren...

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 ...

We present rare complications related to coronary arteries in non-coronary cardiac surgery in adults and pediatrics. Patients and Methods: We retrospectively reviewed our surgical left-sided valve procedures and aortic root reconstruction for patients with documented coronary ostial injury or left circumflex artery (LCX) between January 2012 and December 2019. Preoperative echocardiography was the standard investigation for all cases and other specific work ups were ordered, according to each case. Management by surgical or non-surgical intervention was planned, according to each complication. Postoperative hemodynamics and mortality rate were the outcomes of interest. Results: Seven patients were found to have coronary artery compromise post left-sided valve procedures and aortic root reconstruction in adults and children. The details are shown in Table 1. The complications were in 2 patients pos...

Methodsː 116 cases of sternal wound complications were reviewed retrospectively out of 2391 adult patients underwent full sternotomy for almost cardiac surgery indications from 2006 to 2018. 86 cases of them were managed conservatively and the other 30 required surgical intervention. More objective classification was proposed and less invasive fasciocutaneous flap was reconsidered for almost reconstructive indications. Resultsː The incidence of Sternal wound complications was 4.8%. Conservative management was adopted for 86 cases, mean duration was 11.19±9.8 days. Surgical management was performed in 30 patients (25.86%), twenty eight (93.3%) of them recovered with good outcome...

In addition, we demonstrated the effect of cardiopulmonary bypass (CPB) on vitamin D, parathyroid hormone (PTH), and calcium levels. The association between perioperative vitamin D levels and postoperative clinical outcomes has been explored. A prospective observational study was conducted from February 2018 to June 2019 on 69 children undergoing elective surgery for CHD under CPB. Blood samples were collected preoperatively, immediate postoperatively, and 24 h postoperatively. Vitamin D deficiency was present in 34 (49.3%) patients preoperatively and 63 (91.3%) patients immediately postoperative. We identified 42.03% decline of 25(OH)D immediately postoperative. Changes in ionized calcium (iCa) concentrations were accompanied by reciprocal alterations in PTH concentrations. Lower postoperative 25(OH)D was associated with higher maximum vasoactive inotropic score (VIS) in the first 24 h postoperative (r = − 0.259, p = 0.03).

Materials and methods: We reviewed retrospectively the medical records of all patients with CHD requiring corrective or palliative cardiac surgery at King Abdulaziz University Hospital that needed extracorporeal membrane oxygenation support between November 2015 and November 2018. Results: The extracorporeal membrane oxygenation population was 30 patients, which represented 4% of 746 children who had cardiac surgery during this period. The patients’ age range was from 1 day to 20.33 years, with a median age of 6.5 months. Median weight was 5 kg (range from 2 to 53 kg). Twenty patients were successfully decannulated (66.67%), and 12 patients (40%) were survived to hospital discharge. Patients with biventricular repair tended to have better survival rate compared with those with single ventricle pa...

Its benefits include relieving cardiac compression and stabilizing postoperative critically ill patients. Methods: We retrospectively reviewed the records of 72 patients, who had undergone delayed sternal closure, among 1,254 patients operated for congenital heart diseases. Indications of delayed sternal closure, perioperative hemodynamic and metabolic status, postoperative infection, and mortality were reported. Results: Transposition of great arteries was the most common preoperative cardiac pathology (26.3%). Bleeding and hemodynamic instability were the most frequent indications for delayed sternal closure, representing 38.8% and 34.7%, respectively. The mean duration of open chest was 3.45 days ± 1.46 days. The mean duration of ICU stay was 20.95 days ± 20.06 days. Two patients had deep sternal wound infection. Sepsis was found in 39 patients (54.1%), and the most common causative organism was...
