Background The timing of surgical repair of tetralogy of Fallot (TOF) is a key to alleviate complications and for long-term survival. Total correction was usually performed at the age of 6 months or older under the notion of decreasing the surgical risk. However, avoiding palliation with an aortopulmonary shunt and early correction of systemic hypoxia appear to be of more benefit than the inborn surgical risk in low body weight patients. Our objective was to assess early/midterm survival and operative complications and to analyze patients, surgical techniques, and morphological risk factors to determine their effects on outcomes. Patients and Methods We retrospectively reviewed 152 patients with TOF who were ≤60 days of age when they underwent total correction of TOF. All patients had either duct-dependent pulmonary blood flow or arterial blood oxygen saturation less than 65% on room air requiring urgent surgical correction. Exclusion criteria included TOF with pulmonary atresia, TOF with nonconfluent pulmonary arteries, TOF with multiple aortopulmonary collateral arteries, and associated complete atrioventricular septal defects. Results The mean age at repair was 34 ± 19 days, and the mean weight was 3.8 ± 0.9 kg. Before surgery, 96 patients received an infusion of prostaglandin, 45 were mechanically ventilated, and 32 required inotropic support. Right ventricular outflow tract obstruction was managed with a transannular patch in 112 patients, and all the others had a main pulmonary artery patch. Cardiopulmonary bypass (CPB) with moderate hypothermia was the standard, and the CPB time averaged 48 ± 21 minutes. The postoperative intensive care unit stay was 5.7 ± 6 days, with 2.8 ± 4 days of mechanical ventilation. Early mortality was 4.6% (7 of 152), and actuarial survival rates were 95% at 1 year and 92% at 5 years. Univariable and multivariable analyses of the patients' demographics, anatomical characteristics, and operative techniques revealed the presence of small pulmonary arteries and low body weight to be the only independent risk factors for death. Conclusion Early total correction of TOF during the first 60 days of life can be performed with low mortality and good intermediate-term survival and, from our point of view, “should be the gold standard for TOFs.”

A total correction is a preferred treatment for Tetralogy of Fallot patients in every part of the world. However, the mortality in developing countries was as high as 6.9% to 15.3%. This was a retrospective analytic study that analyzed pre and post-operative risk factors that affected mortality on TOF patients that were performed total correction in Indonesia. A total of 47 TOF patients that were performed total correction from January 2016 to September 2019 were enrolled in this study based on the inclusion criteria. Preoperative and post-operative data were obtained from medical records. In this research, the majority of mortality was found in male patients (39.3%), while the female’s rate was lower (36.8%). Overall mortality was 38.3% and one operative death was found. The average age of patients was 84.12 months (12-210 months), whereas the average height (85.56 ± 36.17cm vs. 112.93 ± 21.73) and weight (17.22kg vs. 28.21kg) were lower for mortality patients. Some significant preoperative variables were identified as mortality risk factors such as: age below 60 months (p=0.047), smaller weight and height (p=0.008; p=0.002), abnormal hematocrit (p=0.002), and oxygen saturation below 75% (p=0.018). Significant post-operative risk factors included: temperature above 38.5⁰C (p=0.000), and ventilator time of more than 48 hours (p=0.033). In conclusion, the mortality of TOF patients undergoing a total correction in developing countries was quite high. It was associated with some risk factors, such as younger age, lower weight and height, low oxygen saturation, post-operative fever, and prolonged ventilator time.

Haemoptysis may occur in patients with tetralogy of Fallot and major aorto-pulmonary collateral arteries. We describe such a patient in whom bleeding from a major aorto-pulmonary collateral artery produced severe pulmonary haemorrhage. Interventional closure of the artery could not be performed because it perfused the native pulmonary arteries. Instead, we inserted a conduit between the right ventricle and the native pulmonary arteries, followed by percutaneous closure of the collateral artery. Our patient demonstrates the increasing necessity for combined surgical and interventional procedures.

Abstract Background and Aims Posttransplant kidney survival depends on several risk factors. A careful immunogenetic matching and the absence of HLA donor specific antibodies (DSA) seem to determine the longevity of the transplant. Method Screening the presence of donor specific HLA antibodies in our posttransplant outpatients was implemented in 2010 (every 6 months in case of DSA free patients for two years, then yearly, and every 3 months in case of DSA + patients for two years, then twice a year). At the same time a treatment protocol was implemented, omitting reduction of immunosuppressive drugs in case of newly detected DSA, and most important with preventing steroid withdrawal in this case.The present single center study reports the long-term survival and kidney function from patients undergoing HLA-screening after transplantation between 2010 and 2016 with a follow-up until 2018. Using a Kaplan-Meier analysis patients without HLA antibodies (no HLA-ab), with HLA antibodies but without DSA (NDSA), and with donor-specific HLA antibodies (DSA) were compared by logrank-testing. Results A full dataset was obtained from 318 patients. The mean overall survival (patients and organ function) didn´t differ between the three groups, p=0.318: no HLA-ab 7.2 years (95%confidence interval 6.7;7.6), NDSA 6.6 (5.9;7.2), DSA 6.8 (6.1;7.5), overall 7.0 (6.6;7.3), events are given in Table1. Whereas the mean patient survival didn´t differ between the groups (p=0.715), the mean death-censored graft survival differed significantly, p=0.008, with a reduced transplant survival in the patients with HLA antibodies but without donorspecific antibodies: no HLA-ab 8.0 years (95%confidence interval 7.7;8.3), NDSA 7.0 (6.4;7.6), DSA 7.6 (7.1;8.2), overall 7.7 (7.4;8.0), numbers are given in Table1. Conclusion In conclusion, the presence of HLA antibodies was associated with a reduced transplant survival. Patients with HLA antibodies had a worse survival than patients with DSA undergoing HLA screening with a personalised immunosuppressive regimen. Immunosuppressive regimen of the groups, as well as other known risk factors of graft survival have to be further analysed. The results of these multivariate analyses have to be awaited to determine whether the risk for graft loss inferred by HLA antibodies is independent from other factors.

AbstractFifteen patients requiring palliation for tetralogy of Fallot were treated by balloon dilation because of hypercyanotic spells. The mean age at dilation was 1.9 ± 0.7 years (range 0.5 – 3), and the mean weight 9.8 ± 2.1kg (range 6.0 –13.5). Dilation of the outflow tract was combined with dilation of the left and/or right pulmonary arteries in 5 patients. Successful dilation was achieved in 12 patients (80%), but failed in 3 patients with hypoplastic pulmonary arteries. In one patient, the stenosis of the right pulmonary artery could not be dilated because of a very sharp angle at the site of the stenosis. Two of the 3 patients in whom the procedure failed died of severe cyanotic spells within 24 hours of the unsuccessful procedure. No major complications occurred during or after the procedure in the cases undergoing successful dilation. The arterial oxygen saturation increased significantly, from 71 ± 5.7% to 89 ± 3.9%, immediately after the procedure (p < 0.005). During a period of follow up of 6 ± 3.7 months (range 1 – 13), the procedure was repeated on 3 occasions, and successfully accomplished in 2 of these. In conclusion, balloon dilation is a satisfactory palliative procedure for tetralogy of Fallot in those units in which total correction is not performed under 2 to 3 years of age.

SummaryThe arterial supply to the lungs in cases with tetralogy of Fallot with pulmonary atresia or critical pulmonary stenosis is mostly via the arterial duct or else by collateral arteries arising directly or indirectly from the aorta. Nine anatomical specimens with collateral arteries were studied by blunt dissection to determine the arterial supply to each pulmonary segment. The precise supply varied from case to case but, overall, nearly two-thirds of the pulmonary segments were connected to the central pulmonary arteries. A quarter were supplied exclusively by systemic-to-pulmonary collateral arteries, with the remainder having a dual supply. Coexistence of ductal connections and systemic-to-pulmonary collateral arteries was seen in one case. Anastomoses between vessels of different origins were observed up to the segmental level in eight of the nine cases. In four cases, the anastomoses formed arterial rings. The extent of pulmonary parenchyma supplied by arteries from different sources and the presence of arterial anastomoses in these malformations have implications on the planning of surgical repair.

Abstract Objective We compared an infrared temporal artery thermometer with our clinical standard axillary thermometer for temperature measurements in neonatal patients. Study Design We measured temporal artery (Tta), axillary (Tax, clinical standard), and rectal (Tr, gold standard) temperatures of 49 infants. The difference between Tr and Tta was compared with that between Tr and Tax, and the data were analyzed based on bed type and postmenstrual age. Results The mean Tta, Tax, and Tr were 37.16 (SD 0.36) °C, 36.61 (SD 0.30) °C, and 36.82 (SD 0.30) °C, respectively. The measurements by these methods were all significantly different. The mean Tr-Tax was 0.21 (SD 0.26) °C, and the mean Tr-Tta was −0.34 (SD 0.37) °C, indicating that Tax was closer to Tr than was Tta (p < 0.0001). Tta agreed more closely with Tr for infants in cribs than for those in incubators. Adjusting for bed type and body weight, with each week of postmenstrual age, the discrepancy between Tr-Tta and Tr-Tax decreased by 0.005°C (p = 0.034). Conclusion Compared with the gold standard, Tr, Tta is not more accurate than Tax. The temporal artery thermometer was less accurate for infants in incubators than for infants in cribs. The accuracy of temporal artery temperature increased with postmenstrual age.

Antegrade Catheterization

SummaryBetween January 1985 and March 1990, 66 children with the tetralogy of Fallot underwent 85 cardiac catheterization procedures. The mean age at first procedure was 2.5 years (range 0.1–;14.4 years) and the mean weight was 10.4 kg ( range 2.4–36.0 kg). Diagnostic cardiac catheterization was performed in 60 procedures and balloon dilatation in 25. Hypercyanotic spells had occurred prior to 24 (28%) of the procedures (all the patients being on propranolol) and a systemic-to-pulmonary arterial shunt had been constructed before 28 (33%) procedures. Of the procedures, 54 (64%) were performed under local and 31(36%) under general anesthesia. The pulmonary trunk was entered antegradely in 52 procedures, retrogradely through a shunt in 6 and not entered in 27. Balloon dilatation was performed under general anesthesia on 25 occasions. No procedure was abandoned because of a cyanotic spell. Nine (11%) spells occurred during 86 procedures, one of the procedures being postponed because ofa spell occurring after premedication, the procedure and not, therefore, continuing to catheterization. Five spells occurred before the catheter was positioned in the heart, 2 spells occurred during catheterization. Of the spells, eight occurred during procedures in children who had not had previous shunts. Antegrade entry into the pulmonary trunk in the group with shunts was associated with no spells compared with 6/38 (18%) in the group not having undergone surgery (p<0.l). In the group not undergoing surgery, when the pulmonary trunk was not entered, 1 (5%) spell occurred during 19 procedures compared with 6/38 (18%) when the pulmonary trunk was entered (p<0.4). The only clinically important factor which significantly influenced the incidence of spells was the use of general anesthesia, which was associated with 6/31 (19%) spells compared with local anesthesia which was associated with 2/54 (4%) spells (p<0.026).

Background The benefits of surgical correction of adult tetralogy of Fallot are well known. The current recommendation is for total correction regardless of age. This study analyzed perioperative factors affecting early outcome after corrective surgery in adulthood in the current era. Methods This was a retrospective chart review of 40 consecutive patients over 18 years of age who underwent total correction of tetralogy of Fallot from September 2006 to June 2013. Patients with pulmonary atresia and absent pulmonary valve were excluded. The mean age at surgery was 26.60 ± 8.69 years (range 18–49 years). Results The mean intensive care unit stay was 3.30 ± 2.29 days (range 0.75–12 days) and hospital stay was 9.97 ± 3.39 days (range 7–22 days). Mortality was 5% (2/40). Multiple parameters indicating immediate postoperative outcomes and their relationships to selected pre-, intra-, and postoperative factors were analyzed. Multivariate analysis showed that postoperative right ventricular dysfunction had a significant influence on mortality ( p < 0.001) and hospital stay ( p = 0.01). Performing zero-balance ultrafiltration decreased the need for renal replacement therapy ( p = 0.034), duration of ventilation ( p = 0.009), incidence of low cardiac output ( p = 0.006), intensive care unit stay ( p = 0.01), and hospital stay ( p = 0.009). Conclusions Total correction of tetralogy of Fallot is a safe option for presentations as late as adulthood. The protective effect of zero-balance ultrafiltration on postoperative morbidity needs to be reassessed in larger studies.
