Second harvest of Congenital Heart Surgery Database in Türkiye: Current outcomes.

Background: This second harvest of the Congenital Heart Surgery Database intended to compare current results with international databases. Methods: This retrospective study examined a total of 4007 congenital heart surgery procedures from 15 centers in the Congenital Heart Surgery Database between January 2018 and January 2023. International diagnostic and procedural codes were used for data entry. STAT (Society of Thoracic Surgeons and European Association for Cardiothoracic Surgery) mortality scores and categories were used for comparison of the data. Surgical priority status was modified from American Society of Anesthesiologist guidelines. Centers that sent more than 5 cases to the database were included to the study. Results: Cardiopulmonary bypass and cardioplegic arrest were performed in 2,983 (74.4%) procedures. General risk factors were present in 22.6% of the patients, such as genetic anomaly, syndrome, or prematurity. Overall, 18.9% of the patients had preoperative risk factors (e.g., mechanical ventilation, renal failure, and sepsis). Of the procedures, 610 (15.2%) were performed on neonates, 1,450 (36.2%) on infants, 1,803 (45%) on children, and 144 (3.6%) on adults. The operative timing was elective in 56.5% of the patients, 34.4% were urgent, 8% were emergent, and 1.1% were rescue procedures. Extracorporeal membrane oxygenation support was used in 163 (4%) patients, with a 34.3% survival rate. Overall mortality in this series was 6.7% (n=271). Risk for mortality was higher in patients with general risk factors, such as prematurity, low birth weight neonates, and heterotaxy syndrome. Mortality for patients with preoperative mechanical ventilation was 17.5%. Pulmonary hypertension and preoperative circulatory shock had 11.6% and 10% mortality rates, respectively. Mortality for patients who had no preoperative risk factor was 3.9%. Neonates had the highest mortality rate (20.5%). Intensive care unit and hospital stay time for neonates (median of 17.8 days and 24.8 days, respectively) were also higher than the other age groups. Infants had 6.2% mortality. Hospital mortality was 2.8% for children and 3.5% for adults. Mortality rate was 2.8% for elective cases. Observed mortality rates were higher than expected in the fourth and fifth categories of the STAT system (observed, 14.8% and 51.9%; expected, 9.9% and 23.1%; respectively). Conclusion: For the first time, outcomes of congenital heart surgery in Türkiye could be compared to the current world experience with this multicenter database study. Increased mortality rate of neonatal and complex heart operations could be delineated as areas that need improvement. The Congenital Heart Surgery Database has great potential for quality improvement of congenital heart surgery in Türkiye. In the long term, participation of more centers in the database may allow more accurate risk adjustment.

Case Report: Neo-ostium creation with saphenous vein in a patient with anomalous origin of the right coronary artery.

Anomalous origin of the right coronary artery from the left sinus of Valsalva is a rare congenital anomaly. Most patients may be asymptomatic, but some may experience major cardiac events such as syncope, arrhythmias, and sudden cardiac death. We present a 16-year-old patient, who had several syncopes, with anomalous origin of the right coronary artery from the left coronary sinus, with an intramural and interarterial course between the pulmonary artery and the aorta. We describe a new surgical procedure of neo-ostium creation with a saphenous vein.

Carotid artery cut-down technique for ductus arteriosus stenting.

Background: This study aims to evaluate early and mid-term outcomes of ductal stenting via carotid artery surgical cut-down technique in neonates. Methods: Between January 2015 and January 2022, a total of 17 neonates (12 males, 5 females; median age: 14 days, range, 5 to 34 days) who underwent carotid artery surgical cut-down technique for ductal stenting were retrospectively analyzed. Diagnoses of the patients, demographics, procedural success/failure, access-related complications, and neuroimaging findings were recorded. Results: The primary indication for ductal stenting was pulmonary atresia in all patients. All patients who underwent carotid cut-down had vertical anatomy, with or without tortuous ductal anatomy, and they were not suitable for the femoral approach. The median body weight was 3 (range, 2 to 3.4) kg. Fifteen of the 17 interventions (88.2%) were successful. Two patients whose stenting failed underwent a systemic-to-pulmonary shunt operation. The early in-hospital mortality rate was 17.6% (n=3). No neurological or accessrelated complications were observed in any of the patients. Conclusion: Stenting the ductus arteriosus with challenging anatomy is feasible and safe with carotid artery cut-down, particularly in small neonates. Based on our study findings, this technique may offer an effective and less invasive alternative to the systemic-to-pulmonary shunt operation.

The effect of extracorporeal membrane oxygenation on neurodevelopmental outcomes in children after repair of congenital heart disease: A pilot study from Turkey.

Background: Extracorporeal membrane oxygenation (ECMO) is widely used after congenital heart surgery. The purpose of this study is to analyze the neurodevelopmental (ND) outcomes in patients who receivedECMO support after congenital cardiac surgery. Methods: Between January 2014 and January 2021, 111 patients (5.8%) receivedECMO support after congenital heart operations, and 29 (26,1%) of these patients were discharged. Fifteen patients who met the inclusion criteria were included. A propensity score matching (PSM) analysis model was established using eight variables (age, weight, sex, Modified Aristotle Comprehensive Complexityscores, seizures, cardiopulmonary bypass duration, number of operations, and repair method) with 1:1 matching. According to the PSM model, 15 patients who underwent congenital heart operations were selected as the non-ECMO group. The Ages & Stages Questionnaire Third Edition (ASQ-3) was used for ND screening;it includes communication, physical skills (gross and fine motor), problem-solving, and personal-social skills domains. Results: There were no statistically significant differences between the patients' preoperative and postoperative characteristics. All patients were followed up for a median of 29 months (9-56 months). The ASQ-3 results revealed that communication, fine motor, and personal-social skills assessments were not statistically different between the groups. Gross motor skills (40 vs. 60), problem-solving skills (40 vs. 50), and overall scores (200 vs. 250) were better in the non-ECMO patients (P = 0.01, P = 0.03, and P = 0.03, respectively). Nine patients (%60) in the ECMO group and 3 patients (%20) in the non-ECMO group were with neurodevelopmental delay (P = 0,03). Conclusion: ND delay may occur in congenital heart surgery patients who receivedECMO support. We recommend ND screening in all patients with congenital heart disease, especially those who receivedECMO support.

Histopathological Changes in the Myocardium Caused by Energy Drinks and Alcohol in the Mid-term and Their Effects on Skeletal Muscle Following Ischemia-reperfusion in a Rat Model.

BACKGROUND: Although energy drinks have been consumed for many years, their effects on the cardiovascular system continue to be investigated. Today, the most frequently used area of energy drinks is the entertainment sector, and this study investigates the effects of energy drinks and alcohol consumption on rats' limb and myocardium tissue. METHODS: Forty Wistar Albino rats were used and divided into 4 groups. Energy drinks were given to the first group (the energy drink group), alcohol was given to the second group, and energy drinks and alcohol were given to the third group Redbull-Alcohol (RA). Blood samples, leg muscles, and heart tissues were studied after the ischemia-reperfusion model was created at the infrarenal level. RESULTS: In the histopathological examination of heart muscles, the damage was significantly more severe in the RA group than in the control group (P <.05). There was no significant change in the RA group in the limb muscle; however, muscle fiber abnormality was higher. The energy drink group was more prone to carbon dioxide retention and hypoxia, resulting in respiratory acidosis. (P =.05). Lactate was significantly higher in the energy drink group (P =.002). Glucose concentrations of energy drink and RA groups were higher (P =.02). CONCLUSION: The high lactate values of the energy drink group and more damaged fibers in the striated muscles in the RA group showed that they are more susceptible to ischemia. Long-term energy drinks and alcohol use may cause damage to the heart muscle and endothelium. Also, the effects of long-term alcohol and energy drink use on the respiratory system should be investigated with more specific studies.

Early postnatal metabolic profile in neonates with critical CHDs.

BACKGROUND: Cyanotic CHD is a life-threatening condition that presents with low oxygen saturation in the newborn period. Hypoxemia might cause alterations in the metabolic pathways. In the present study, we aimed to evaluate the early postnatal amino acid and carnitine/acylcarnitine profiles of newborn infants with cyanotic CHD. METHODS: A single centre case-control study was conducted. Twenty-seven patients with cyanotic CHD and 54 healthy newborn controls were enrolled. As part of the neonatal screening programme, results of amino acid and carnitine/acylcarnitine were recorded and compared between groups. RESULTS: Twenty-seven neonates with cyanotic CHD and 54 healthy newborns as controls were enrolled in the study. Cyanotic CHD neonates had higher levels of alanine, phenylalanine, leucine/isoleucine, citrulline, ornithine, C5, C5-OH; but lower levels of C3, C10, C12, C14, C14:1, C16, C16.1, C18, C5-DC, C6-DC, C16-OH, C16:1-OH when compared with the healthy controls. CONCLUSION: This study showed that there are differences between patients with cyanotic CHD and healthy controls in terms of postnatal amino acid and carnitine/acylcarnitine profiles.

Outcomes of Extracorporeal Membrane Oxygenation in Patients After Repair of Congenital Heart Defects.

Extracorporeal membrane oxygenation (ECMO) is widely used after congenital heart surgery. The purpose of this study is to analyze the factors influencing mortality and morbidity in patients who require ECMO support after congenital cardiac surgery. All 109 patients (5.8% of total cases) who underwent ECMO support after congenital heart surgery between January 2014 and 2021 were included in this single-center study. The mean age was 10.13 ± 20.55 months, and the mean weight was 6.41 ± 6.79 kg. 87 (79.8%) of the patients were under 1 year of age. A total of 54 patients (49.5%) were weaned successfully from ECMO support, and 27 of them (24.8%) were discharged. The childhood age group had the best outcomes. Seventy-seven percent of the children were weaned successfully, and 50% were discharged. 69 patients (63.3%) had biventricular physiology; weaning and survival outcomes were better than single ventricle patients (P-value 0.002 and < 0.001, respectively). Low cardiac output (n = 49; 44.9%) as an ECMO indication had better outcomes than extracorporeal cardiopulmonary resuscitation (n = 31; 28.4%) (P = 0.05). Most of the patients had ≥ 4 Modified Aristotle Comprehensive Complexity (MACC) levels, and higher MACC levels were associated with a higher mortality rate. The most common procedure was the Norwood operation (16.5%), with the worst outcome (5.5% survival). Bleeding and renal complications were the most common complications affecting outcomes. Results were more satisfactory in patients with biventricular repair, childhood, and lower MACC levels. Early initiation of ECMO in borderline patients without experiencing cardiac arrest or multiorgan failure may improve outcomes.

A complete case of Cantrell's Pentalogy with isolated left ventricular diverticulum.

The congenital left ventricular diverticulum is a rare cardiac malformation, and it may associate with Cantrell's Pentalogy with other cardiac defects. However, isolated ventricular diverticulum without any other cardiac defect in complete Cantrell's syndrome is very rare. We describe a 6-year-old male patient with a complete Cantrell's syndrome with isolated left ventricular diverticulum.

Does a prenatal diagnosis affect mortality and morbidity for neonatal arterial switch operation.

BACKGROUND: The effect of prenatal diagnosis on prognosis in patients with transposition of the great arteries is not clear. In this study, we compared the outcomes after arterial switch operation. METHODS: Outcome of 112 patients who had arterial switch operation in the neonatal period were analysed. The patients were divided into two groups: those who had prenatal diagnosis (Group 1; n = 34) and those who did not (Group 2; n = 78). The patients were also classified based on their diagnosis: simple transposition, transposition with ventricular septal defect and/or aortic arch hypoplasia, and Taussig-Bing anomaly. RESULTS: In Group 1, the C-section delivery rate was higher (82% vs. 44%; p = 0.004), and it was observed that patients in Group 1 were more often intubated upon admission to the neonatal ICU (38% vs. 9%; p = 0.005). No differences were found between the two groups in terms of operation time, cardiopulmonary bypass time, post-operative invasive respiratory support duration, or extracorporeal membrane oxygenation support. It was observed that those who had Taussig-Bing anomaly had a higher mortality. CONCLUSIONS: Timely treatment have a positive effect on neonatal mortality and morbidity. That's why all families with prenatal diagnosis of critical CHD should be recommended to have the delivery in a tertiary care hospital. Although it could not be demonstrated in this study, prenatal diagnosis has a potential to improve surgical results especially in countries or cities, which does not have enough resources for transfer and surgical units. Further efforts are needed to improve prenatal screening programmes.

Analysis of outcomes in patients with abnormal laterality undergoing congenital heart surgery.

OBJECTIVE: Laterality anomalies are almost always associated with severe cardiac anomalies. Demographic properties, type of the procedures, associated anomalies, and early and mid-term prognosis of four types of laterality anomalies were analysed. METHODS: A total of 64 consecutive patients with laterality anomalies were enrolled between July 2014 and July 2020. We grouped the patients as situs solitus dextrocardia (SSD) (n = 12; 18.7%); situs inversus (SI) (n = 16; 25%); right atrial isomerism (RAI) (n = 29; 45.3%); and left atrial isomerism (LAI) (n = 7; 10.9%). TAPVC was only present in the RAI group (31%). Incidence of mitral or tricuspid atresia was higher in the SSD group (25%). All the patients were followed up with a mean of 19.06 ± 17.6 (0.1-72) months. RESULTS: Early postoperative mortality was 17 patients, among 107 procedures (15.8%). Twelve patients were in the neonatal period. All ten patients survived after isolated ductal stenting. Fourteen of the deaths were in the RAI group (48.3%). The 3-year survival rates were 85% in LAI, 78.7% in SI, 55.8% in SSD, and 38% in RAI groups. According to the multivariable Cox regression model, mechanical ventilation, kidney injury, RAI, and complex surgery in the neonatal period were independent risk factors for early mortality. CONCLUSION: Laterality anomalies are one of the most challenging patients who commonly had univentricular physiology. The most prevalent anomaly was RAI, and RAI had the worst outcome and survival. Ductal stent is an acceptable first intervention during the neonatal period in suitable patients. Complex procedures may carry a high risk of death in the neonatal period.

Toward Routine Minimally Invasive Ventricular Septal Defect Closure Via Right Lateral Minithoracotomy.

Background: Improving the surgical results and recent advancement of transcatheter techniques for closure of ventricular septal defect (VSD) increased the demand for minimally invasive approaches. In this study, we analyzed the results of the patients who underwent VSD closure with right lateral minithoracotomy (RLMT). Methods: Between September 2014 and February 2021, 24 patients underwent minimally invasive VSD closure with RLMT. The median age of the patients was 16 months (range, 4-84 months). Fifteen patients (62.5%) were female. The median weight of the patients was 9.75 kg (range, 4.6-30 kg). The types of VSD were perimembranous in 19 patients, subaortic in three patients, inlet in one patient, and subpulmonic in one patient. Five patients had low-lying pulmonary stenosis in addition to VSD. Results: No perioperative death or major complication occurred during follow-up. All defects were repaired through RLMT. The median cardiopulmonary bypass time was 81 min (range, 44-163 min), and the aortic cross-clamp time was 65 min (range, 33-131 min). The median hospital stay was 6 days (range, 5-21 days). One patient had minimal (2 mm) residual left-to-right shunt. All families were satisfied with the cosmetic results during the follow-up. Conclusions: The RLMT method is a safe and effective alternative to standard median sternotomy for VSD closure and can be performed with favorable cosmetic and clinical results.

Repair of complete atrioventricular canal defects: Early and midterm results and comparison of the left anterior leaflet augmentation technique with traditional technics.

BACKGROUND: Complete atrioventricular septal defects (CAVSD) include a variable spectrum of congenital malformations with different forms of clinical findings. We examined early and midterm outcomes, the need for reoperation, postoperative residual AV valve regurgitation, and other risk factors after various CAVSD repairs. METHODS: Between 2014 and 2018, we have performed 89 isolated CAVSD repairs. We retrospectively reviewed the patients' medical records. Patients were divided into three groups according to their repair techniques modified one patch repair (MP) (n = 16); two patch repair (TP) (n = 49); and left anterior leaflet augmentation (ALA) technique (n = 24). RESULTS: Eighty patients (89.8%) survived hospital discharge. Early mortality rates were three (18.8%) in the group MP, five (10.2%) in the group TP, and one (4.2%) in the group ALA. Thirteen patients died during the follow-up period. Late mortality rates were three (18.8%) in the group MP, four (16.6%) in the group ALA, and six (12.2%) in the group TP. The mean follow-up time was 35.9 ± 22.97 months (range: 0.3-77 months). The morbidity and mortality results were similar between-group TP and ALA but worse in the MP group. Low body weight (<4 kg) and younger age at surgery (<4 months) were found to be risk factors on mortality by univariate and multivariate analysis. Surgical technic was not found to be an independent risk factor. CONCLUSION: In our series, TP and ALA techniques had satisfactory results in early and midterm periods. Younger age and small bodyweight might increase early mortality and the need for reoperation.

Outcomes of home mechanical ventilation with tracheostomy after congenital heart surgery.

OBJECTIVE: After congenital heart surgery, some patients may need long-term mechanical ventilation because of chronic respiratory failure. In this study, we analysed outcomes of the patients who need tracheostomy and home mechanical ventilation. METHODS: Amongst 1343 patients who underwent congenital heart surgery between January, 2014 and June, 2018, 45 needed tracheostomy and HMV. The median age of these patients was 6.4 months (12 days-6.5 years). Nineteen patients underwent palliation while 26 patients underwent total repair. Post-operative diaphragm plication was performed in five patients (11%). Median duration of mechanical ventilation before tracheostomy was 32 days (8-154 days). The patients were followed up with their home ventilators in ward and at home. Mean follow-up time was 36.24 ± 11.61 months. RESULTS: The median duration of ICU stay after tracheostomy was 27 days (range 2-93 days). Follow-up time in ward was median 30 days (2-156 days). A total of 12 patients (26.6%) were separated from the ventilator and underwent decannulation during hospital stay. Thirty-two patients (71.1%) were discharged home with home ventilator support. Of them, 15 patients (46.9%) were separated from the respiratory support in median of 6 weeks (1 week-11 months) and decannulations were performed. Total mortality was 31.1%. in which four patients are still HMV dependent. There was no significant difference for decannulation between total repair and palliation patients. CONCLUSION: HMV via tracheostomy is a useful option for the treatment of children who are dependent on long-term ventilation after congenital heart surgery although there are potential risks.

Management of aortic arch hypoplasia in neonates and infants.

OBJECTIVES: Surgical management of aortic arch hypoplasia (AAH) with associated intracardiac anomalies is a challenge in newborns. We reviewed the characteristics and outcomes of neonates and infants who underwent pulmonary artery banding concomitant to arch repair and single-stage total repair at our institution. METHODS: Medical records of 60 patients undergoing aortic arch reconstruction for AAH from 2014 to 2019 were retrospectively reviewed. Twenty-five patients were female (41.6%), and the age of the patients ranged from 4 to 120 days (median, 19.5 days). The patients were divided into two groups: Group 1 (23 patients) underwent pulmonary artery banding concomitant to arch repair, and Group 2 (37 patients) underwent single-stage total repair in addition to arch repair. All arch repair procedures consisted of an extended (to the midportion of the ascending aorta) patch aortoplasty. RESULTS: Postoperative early mortality occurred in 12 patients, eight in Group 1 (34.8%) and four in Group 2 (10.8%). There was an early survival advantage in Group 2 (p = .019). Recoarctation occurred in 13 cases (21.6%), and 11 (18.3%) of them required reintervention (balloon angioplasty: 7, reoperation: 4). On univariate analysis, risk factors associated with death were pulmonary artery banding (hazard ratio [HR], 0.44; confidence interval [CI], 0.09-2; p = .019), prematurity (HR, 4.67; CI, 1.34-16.18; p = <.001), preoperative mechanical ventilation support requirement (HR, 0.048; CI, 0.52-6.39; p = .048), and functional single ventricle (HR, 0.43; CI, 0.1-1.86; p = .006). The mean duration of follow-up was 21.9 ± 15.1 months, and there was no late death in either group. CONCLUSION: Single-stage repair of AAH with intracardiac pathologies has better results than palliation, according to survival rates and postoperative results. The use of the patch augmentation technique in AAH is valid and associated with an acceptable incidence of recurrent arch obstruction.

A comparison of robotically-assisted endoscopic versus sternotomy approach for myxoma excision: A single-center experience.

BACKGROUND: In this study, we present our single-center experience in robotically-assisted endoscopic surgery versus conventional median sternotomy approach in patients undergoing cardiac myxoma excision. METHODS: Between January 2011 and September 2019, a total of 46 patients (24 males, 22 females; mean age 54.1±12.5 years; range, 25 to 79 years) who had a confirmed diagnosis of isolated cardiac myxoma were included in the study. The patients were divided into two groups as those undergoing robotic-assisted surgery (n=16) and those undergoing conventional median sternotomy (n=30). Clinical characteristics, operative, and postoperative outcomes were compared. Robotic approach to right or left-sided tumors and postoperative pain scores were also analyzed. RESULTS: There was no mortality or major complication. No conversion to sternotomy was needed in robotic procedures. The mean cardiopulmonary bypass and aortic cross-clamp times were significantly shorter in the median sternotomy group (p=0.001 for both). The mean ventilation time and the length of hospital stay were significantly shorter in robotic surgery than sternotomy group (p=0.043 and p=0.048, respectively). The mean amount of postoperative blood loss and transfusion rate were significantly lower in robotic surgery patients (p=0.001 and p=0.022, respectively). The mean postoperative pain scores were significantly lower in patients undergoing robotic surgery (p=0.022). CONCLUSION: Robotic-assisted endoscopic surgery can be performed safely and effectively for cardiac myxoma excision with shorter hospital stay, less pain, and less amount of blood product use, as well as more favorable cosmetic results compared to conventional median sternotomy.

Effect of Pulsatile Cardiopulmonary Bypass in Adult Heart Surgery.

BACKGROUND: This study aimed to examine the effect of pulsatile flow pattern on tissue perfusion, particularly cerebral tissue perfusion, at pre-determined intervals during CPB, as well as its effects on postoperative morbidity and mortality. METHODS: This retrospective study included 134 adult patients, who underwent cardiac surgery with cardiopulmonary bypass (CPB). Patients were grouped based on the flow pattern used during CPB: non-pulsatile CPB group (N = 82) and pulsatile CPB group (N = 52). Cerebral oxygen saturation, arterial pH and arterial lactate levels were measured at four time points, during the operation and the 2 groups were compared with regard to changes over time as well as differences in postoperative outcomes. RESULTS: The 2 groups were similar, in terms of mean values and intraoperative changes in cerebral oxygen saturation and arterial pH. Non-pulsatile CABG group had significantly higher arterial lactate levels over the measurement period, which was not affected by the timing of the measurements. Postoperative drainage, duration of ventilation and duration of hospital stay significantly were higher and postoperative blood urea nitrogen significantly was lower in the non-pulsatile CPB group. Other postoperative outcomes were similar across the groups. CONCLUSION: Findings of this study do not support the superiority of pulsatile flow pattern during CPB, in terms of cerebral oxygen saturation or postoperative mortality/morbidity. Further and larger comparative studies are warranted before pulsatile blood flow pattern can be established as a routine clinical method.

Robotic-assisted cardiac surgery without lung isolation utilizing single-lumen endotracheal tube intubation.

OBJECTIVES: This study assessed the feasibility and outcomes of performing robotic cardiac surgery without lung isolation using single-lumen (SL) endotracheal tube intubation. METHODS: Between 2013 and 2017, 132 patients underwent robotically-assisted atrial septal defect closure. A retrospective analysis was performed of 23 patients (11 males, mean age 30.9 ± 5 years) who underwent robotic surgery with double-lumen (DL) endotracheal tube intubation (group 1) compared with 109 patients (57 males, mean age 32.4 ± 7.5 years) undergoing the same procedure with SL endotracheal intubation (group 2). The patient groups were compared in terms of demographic characteristics, operative data, and complications. The technical feasibility of the robotic procedure without lung isolation was evaluated. RESULTS: There were no mortality, intraoperative complication, and conversion. Mean total anesthesia time was significantly decreased in the SL intubation group (238.3 ± 22.4 vs 227.2 ± 21.2 minutes; P = .025). First-pass intubation success was significantly higher in the SL intubation group (17 [73.9%] vs 98 [89.9%] patients; P = .032). Mean ventilation time (10.9 ± 5.3 hours), intensive care unit stay (16.8 ± 10.1 hours), and the length of hospital stay (3.8 ± 1.2 days) was significantly decreased in patients with SL tube (P < .05). Unilateral reexpansion pulmonary edema was observed in five (21.7%) patients with DL tube, whereas no patient with SL tube had this complication. CONCLUSIONS: SL endotracheal tube intubation without lung isolation is a feasible and safe airway alternative in robotic cardiac procedures. This approach resulted in shorter anesthesia time, ventilation time and the length of hospital stay. Port placement and robotic set-up can be uneventfully performed without lung isolation.

Transcatheter closure vs totally endoscopic robotic surgery for atrial septal defect closure: A single-center experience.

BACKGROUND: Transcatheter closure is the preferred method for atrial septal defect (ASD) closure. Robotic surgery has become the least invasive technique for ASD closure. Therefore, we sought to evaluate the outcomes in patients who underwent ASD closure with transcatheter or robotic surgery techniques. METHODS: A total of 462 patients underwent totally endoscopic robotic (n = 217) or transcatheter ASD closure (n = 245). Demographic data, perioperative data, and outcomes were compared. RESULTS: The mean age was lower in the robotic surgery group than the transcatheter group (31.4 ± 11.8 vs 39.4 ± 13.2 years; P = .001). Ventilation time, intensive care unit (ICU) stay, and hospital stay was significantly lower in the transcatheter group. The postoperative new-onset neurological event was seen in one (0.5%) patient in robotic surgery, and four (1.6%) patients in the transcatheter closure group. New-onset atrial fibrillation was found to be higher in transcatheter closure (two vs seven patients; P = .133) group. Surgical conversion to a larger incision occurred in two patients (1%) in robotic surgery, while two patients (0.5%) underwent emergency median sternotomy due to device embolization to the main pulmonary artery. There was no mortality in both groups. During follow-up, one patient (0.5%) who underwent robotic surgery was reoperated, and two patients (0.8%) who underwent transcatheter procedure required surgical intervention due to device migration and severe residual shunting (P = .635). CONCLUSION: Both transcatheter and robotic surgery approaches had excellent outcomes but transcatheter closure had shorter hospital and ICU stays. Robotic surgery provides a similar complication risk that can be comparable to the transcatheter approach as well as patient comfort and cosmetic advantage over the other surgical techniques.
