RESUMO

Bicuspid aortic valve is the most common congenital cause for the development of aortic valve calcification and stenosis. Calcification cause valvular stenosis or valvular insufficiency due to coaptation failure. We report a unique case of calcification of bicuspid valve was extending to left ventricular outflow tract and attached to interventricular septum which caused subvalvular stenosis.

RESUMO

BACKGROUND AND AIM OF THE STUDY: After congenital cardiac surgery, the duration of mechanical ventilation (MV) is related to the clinical status, type of operation, and the sedative-analgesic agents used postoperatively. This study aims to examine the effects of dexmedetomidine and morphine on the fast-track extubation (FTE) and ultra-fast-track extubation (UFTE) protocol after congenital cardiac surgery. METHODS: A total of 251 pediatric patients were divided into two groups: 118 patients in the morphine group (Group M) and 133 patients in the dexmedetomidine group (Group D). We retrospectively reviewed medical data including hemodynamic parameters, duration of MV and cardiovascular intensive care unit (CICU), additional sedative/analgesic requirement, adverse events, the need for reintubation, and noninvasive MV, sedation, and pain scores. RESULTS: The mean mechanical ventilation duration of Group D was significantly shorter than Group M (3.74 ± 0.83 h in Group D, 5.72 ± 1.54 h in Group M, respectively) (p = .001; p < .05). In Group D, the success rate of FTE was 92.5% (n = 123) and UFTE was 7.5% (n = 10) (p = .001). In Group M, the success rate of FTE was 72.9% (n = 86) and UFTE was 0% (n = 0) (p > .05). CONCLUSIONS: Dexmedetomidine and morphine have clinical benefits which encourage their use for FTE protocol. Dexmedetomidine has more benefits compared to morphine. It can be used in UFTE protocol, besides its use in FTE protocol with fewer side effects.

RESUMO

BACKGROUND AND AIM OF THE STUDY: Transfusion-associated hyperpotassemia is a serious complication of packed red blood cell (PRBC) transfusion after congenital cardiac surgery. Our study aimed to identify risk factors and potential preventive measures of transfusion-associated hyperpotassemia in neonates and infants after congenital cardiac surgery. METHODS: Pediatric patients who underwent congenital cardiac surgery and need transfusion were enrolled in this prospective study. The potassium concentration of PRBC was checked from the sample taken from the segment. The volume of transfusion, age of PRBC, potassium concentration of unit were recorded. The estimated increment of potassium level in patients after PRBC transfusion was calculated. RESULTS: Seventy-four individual patients, 95 distinct transfusions, 112 blood products were evaluated. The mean age of the blood unit was 3.8 ± 1.4 days. The mean potassium concentration in the PRBCs was 9.9 ± 2.4 mmol/L. A weak correlation was observed between the potassium value of the PRBC and the age of PRBC (p = 0.049, r = 0.2, y = 0.24 × x + -0.68). There was a weak correlation between the potassium value of PRBCs and the age of the unit (p < 0.001, r = 0.37, y = 2.8 × x + -3.6). CONCLUSIONS: Before transfusion, even PRBC is fresh, measuring the potassium level of PRBC and the potassium that will be given to the pediatric patient with transfusion can prevent transfusion-related hyperpotassemia and related complications. Otherwise, high potassium levels, which may be overlooked despite being fresh, may cause serious complications, even cardiac arrest, especially in neonates and infants.

RESUMO

Sternal closure can lead to hemodynamic and respiratory instability after some complex pediatric cardiac surgeries. In such cases, delayed sternal closure is applied to facilitate postoperative recovery. During open sternum several instruments have been defined to prevent the sternum from compressing the heart; however, most of them have limitations. We, therefore, have attempted to use a new instrument to keep the sternum open in neonates and infants. This instrument has been used as an adult eye speculum which is made of a flexible metal wire. It is delicate, ready to use, easily placed, and good fitted to the pediatric sternal edges.

RESUMO

BACKGROUND: Limited data exist regarding the coronary revascularization procedures needed during the repair of several congenital and pediatric cardiac malformations. We aimed to determine risk factors for in-hospital mortality and long-term outcomes of various pediatric coronary revascularization procedures. METHODS: We retrospectively reviewed the records of 32 consecutive pediatric patients who underwent coronary revascularization procedures at our institution between May 1995 and June 2020. In-hospital mortality, risk factors, surgical indications, revascularization patency, and mid- and long-term follow-up data were investigated. Patients were categorized into the coronary artery bypass grafting (n = 11) and other coronary artery procedure (n = 21) groups. RESULTS: The median age and weight of patients at the time of surgery were 9 months and 4.8 kg, respectively. There were five in-hospital deaths (5/32, 15.6%). The mortality rates were 27.2% (3/11) in the coronary artery bypass grafting group and 9.5% (2/21) in the other coronary artery procedure group (p = .206; 95% confidence interval: 0.496-25.563). The mortality rates for planned and rescue procedures were 8.3% (2/24) and 37.5% (3/8) (p = .06), respectively. The median follow-up time was 12.5 years. Control imaging studies for coronary patency were performed in 70.3% (19/27) of surviving patients. The overall coronary patency rate was 94.7% (18/19). CONCLUSIONS: Pediatric coronary revascularization procedures with elective-planned indications can be performed with good outcomes. Young age and rescue and emergency procedures may carry an increased risk of in-hospital mortality, although not found to be statistically significant. Surviving patients require lifelong follow-up regarding the patency of reperfused coronary arteries.

RESUMO

We described a very rare case of aorto-pulmonary communication with right aortic arch and crossed pulmonary artery that cannot be placed in the typical anatomic classification of aortopulmonary window. At 23 weeks gestation, fetal echocardiography revealed a large tunnel-like communication connecting the great vessels proximal to the main pulmonary artery bifurcation, rather than a classic aortopulmonary window between the ascending aorta and the main pulmonary artery.

RESUMO

BACKGROUND: Postoperative thoracic aortic graft infection (TAGI) is a serious and potentially fatal complication. The classical approach is to replace the infected graft. However, this approach has a high mortality rate. Alternatively, treatment of TAGI without graft replacement can be performed METHOD: Herein, we present a 72-year-old case with mediastinitis and graft infection after type A aortic dissection operation and successful treatment using omental flap coverage following vacuum-assisted wound closure therapy without graft replacement. CONCLUSION: The patient had an uneventful postoperative course and remains infection-free to date.

RESUMO

Background and aim: In patients undergoing congenital cardiac surgery, it is crucial to maintain oxygen demand-consumption balance. Central venous oxygen saturation (ScvO2) is a useful indicator of oxygen demand and consumption balance which is an invasive method. Near-infrared spectroscopy (NIRS) is a noninvasive, continuous monitoring technique that measures regional tissue oxygenation. NIRS that is placed over the internal jugular vein cutaneous area (NIRSijv) has the potential to show ScvO2 indirectly. In this study, we aimed to determine the correlation between ScvO2 with NIRSijv in pediatric patients undergoing congenital cardiac surgery. Materials and methods: Fifty children participated in the study. Four patients were excluded for the inability of internal jugular vein (IJV) catheterization due to technical difficulties. After anesthesia induction, NIRS probes were placed on the IJV site with ultrasound guidance for the measurement of continuous transcutaneous oxygen saturation. The catheter insertion was also done through the IJV from the other side using ultrasound guidance. Cerebral oxygenation monitoring was done using NIRS with a single pediatric probe placed on the right forehead. Values of NIRSijv, cerebral NIRS (NIRSc) and ScvO2, were recorded at certain times until postoperative 24th hour. Results: Data were collected at 8 different time points. There was a significant correlation between ScvO2 and NIRSijv in all measurement time points (r = 0.91), (P = 0.001). The mean bias between ScvO2 and NIRSijv was 2.92% and the limits of agreement were from 11% to ­5.2%. There was a moderate correlation between ScvO2 and NIRSc (r = 0.45), (P = 0.001). The mean bias between ScvO2 and NIRSc was 2.7% and the limits of agreement were from +26% to ­20%. Conclusions: In this study, we found a strong correlation between ScvO2 and NIRS measurements taken from the internal jugular vein site. Accordingly, continuous noninvasive monitoring with transcutaneous NIRSijv can be an alternative method as a trend monitor for the central venous oxygen saturation in pediatric cardiac patients undergoing congenital cardiac surgery.

RESUMO

Pulmonary valve preservation in tetralogy of Fallot (TOF) repair is one of the most challenging issues. Herein, we describe a novel valve-sparing technique for TOF repair that primarily consists of skeletonization of the anterior part of the pulmonary annulus and gentle dilatation by preserving the pulmonary valve and annulus integrity. With encouraging early results, this technique is suggested to prevent severe pulmonary regurgitation and provide acceptable relief of pulmonary stenosis in patients with TOF.

RESUMO

BACKGROUND: We present our clinical experience with coronary artery bypass grafting (CABG) in children. METHODS: Ten children who underwent CABG between July 1995 and August 2017 were retrospectively analyzed. Data including congenital cardiac malformations, previous surgical procedures, age and sex, type of coronary complications, ischemic events preceding surgery, and ventricular function before and after CABG were recorded. RESULTS: The study population consisted of five males and five females with a median age of 2.5 years (range, 88 days to 15 years). Eight internal mammary arteries (IMAs) and two saphenous veins were used for grafting. Indications for bypass grafting were coronary artery (CA) complications related to the post-arterial switch operation in six, CA complications during the Ross procedure in two, and an iatrogenic CA injury during complete repair of tetralogy of Fallot with abnormal CA, crossing the right ventricular outflow tract in two patients. Six of the grafts were performed as rescue procedures. Three patients died during hospitalization. The mean follow-up time was 6.8 years (range, 3 months to 18 years). Anastomoses were evaluated by coronary angiography in four patients, and were all patent. Echocardiography revealed normal myocardial function in all patients. CONCLUSION: Our study suggests that the IMA should be the graft of choice in children due to its growth potential and long-term patency.

RESUMO

UNLABELLED: Cardiac pseudoaneurysm is an extremely rare condition in children. It can be congenital or acquired and has been primarily described in the left side of the heart. The congenital form of pseudoaneurysm is thought to be related to muscular dysplasia of the muscular layer of the heart. The acquired form is related to myocardial infarction, infective endocarditis or chest trauma. In this report we described a 5-month-old baby with left atrial pseudoaneurysm who was referred to our hospital due to tachycardia and hemodynamic instability. After diagnosis of left atrial pseudoaneurysm, aneurysmectomy was performed and the left atrial wall was successfully repaired by surgery three days after admission. In conclusion, due to life threatening complications such as dissection, arrhythmias, compression of aneurysm and tromboembolic complications, pseudoaneurysm should be treated by surgery. KEY WORDS: Chest trauma; Left atrial pseudoaneurysm; Supraventricular arrhythmias.

RESUMO

OBJECTIVES: Modified ultrafiltration is used to ameliorate the deleterious effects of cardiopulmonary bypass in pediatric cardiac surgery patients. The ideal duration of modified ultrafiltration has not been established yet. We investigated the effects of extended duration of modified ultrafiltration on pulmonary functions and hemodynamics in the early postoperative period in newborns and infants who had transposition of great arteries operations. DESIGN: Single-center prospective randomized study. SETTING: Pediatric cardiac surgery operating room and ICU. PATIENTS: Sixty newborns and infants who had been scheduled to undergo transposition of great arteries operation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Modified ultrafiltration was applied to all patients following the termination of cardiopulmonary bypass (for 10, 15, and 20 min in groups 1, 2, and 3, respectively). Pulmonary compliance, gas exchange capacity, hemodynamic measurements, inotropic support, blood loss, transfusion requirements, hematocrit level, and duration of ventilatory support were measured after intubation, at termination of cardiopulmonary bypass, at the end of modified ultrafiltration, and in the 1st, 6th, 12th, and 24th hours after admission to ICU. The amount of fluid removed by modified ultrafiltration in groups 2 and 3 was larger than that of group 1 (p < 0.01). Systolic blood pressure was significantly increased at the end of modified ultrafiltration in group 3 compared to groups 1 and 2 (p < 0.05). Hematocrit levels were significantly increased at the end of modified ultrafiltration in groups 2 and 3 compared to group 1 (p < 0.01). Therefore, RBCs were transfused less after modified ultrafiltration in groups 2 and 3 compared to group 1 (p < 0.05). Static and dynamic compliance, oxygen index, and ventilation index had improved similarly in all three groups at the end of modified ultrafiltration (p > 0.05) CONCLUSIONS:: Modified ultrafiltration acutely improved pulmonary compliance and gas exchange in all groups. Increased hematocrit and blood pressure levels were also observed in the longer modified ultrafiltration group. However, extended duration of modified ultrafiltration did not have a significant impact on duration of intubation or the stay in ICU.

RESUMO

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.

RESUMO

The combination of hypothermia and potassium cardioplegic arrest has become the most common method of myocardial protection in the evolution of myocardial protection. This review focuses on myocardial protection in pediatric cardiac surgery. In the 1980s, blood was added to cardioplegia solution in order to supply the myocardium with oxygen, nutrients, and for buffering purposes. Similar myocardial protection methods have been used in adult and pediatric groups for many years. However, the immature heart in the pediatric group differs in many ways from the mature hearts in adults. Low cardiac output is more often observed in pediatric patients. Most cardiac operations are performed under cardioplegic arrest in pediatric cardiac surgery. Today there are a lot of different types of cardioplegia solutions and methods used in pediatric cardiac surgery. Soon after normothermic perfusion was used in the adult cardiac surgery in the beginning of the 1990s, normothermic perfusion and cardioplegia began to be used in pediatric myocardial protection. Myocardial protection is more challenging in particular cases such as: (i) long and complex cases in which repetitive cardioplegia administration through the aortic root is difficult; (ii) newborn patients; and (iii) cases with preoperative damaged myocardium. If the mortality and morbidity rates of the centers in complex and long procedures are higher than the reported rates in literature, the myocardial protection method must be suspected and reorganized.

RESUMO

The Fontan procedure is employed as the final-stage palliation in single-ventricle congenital heart patients and results in diversion of venous blood directly to the pulmonary arteries. Fontan patients have been known to suffer from postoperative systemic venous hypertension, which in turn is associated with pleural effusions and protein losing enteropathy, leading to a decreased duration and quality of life. Despite the ongoing debate on its benefits, a circular fenestration hole (typically 4 mm) establishing a venous shunt to the common atrium is traditionally employed to relieve venous pressure in the Fontan conduit and improve early postoperative Fontan hemodynamics. However, these improvements come at the cost of reduced oxygen saturation due to excessive right-to-left shunting if the fenestration is permanent. The ideal "selective" fenestration would therefore limit or eliminate shunt flow at tolerable systemic venous pressures and allow increased flow at high pressures. The objective of this study is to introduce new fenestration designs that exhibit these desirable pressure-flow characteristics. Novel plus-shaped and S-shaped fenestration designs with leaflets are introduced as alternatives to the traditional circular fenestration, each having identical effective orifice areas at the fully open states. In vitro steady leakage flow tests were performed for physiological flow-driving pressures in order to obtain pressure-drop versus flow-rate characteristics. In addition, the leaflet opening kinematics of the plus-shaped fenestration was investigated computationally using finite element simulation. Fluid-structure interaction analysis was performed to determine leaflet displacements and pressure-flow characteristics at low pressures. Further, a lumped parameter model of the single-ventricle circuit was created to simulate pulsatile flow conditions For the plus-shaped fenestration, the flow rate was found to increase nonlinearly with increased driving systemic venous pressures at high physiological-pressure drops which did not cause the leaflets to fully open, and linearly for low driving pressures. These results indicate that leaflets of the plus-shaped fenestration design activated passively after a critical systemic venous pressure threshold. This feature is ideal for minimizing undesirable excessive venous shunting. A large variability in shunting flow rate may be obtained by changing the shape, thickness, size, and material of the fenestration to suit requirements of the patient, which can further limit shunt flow in a controlled manner.

RESUMO

Aneurysmal circumflex coronary artery fistula connected to the coronary sinus is a rare clinical entity that usually remains asymptomatic until later in life. The timing of surgical treatment for asymptomatic patients is crucial. The decision to leave or exclude the aneurysmatic coronary artery following ligation of the fistula is controversial. Herein, we report the successful management of a coronary fistula between the circumflex artery and the coronary sinus without using cardiopulmonary bypass during the newborn period.

RESUMO

BACKGROUND: Thoracotomy causes severe pain in the postoperative period. Perioperative thoracic paravertebral block reduces pain score and may improve outcome after pediatric cardiac surgery. This prospective study was designed for the efficacy and duration of a single level, single injection ultrasound-guided thoracic paravertebral block (TPVB) for fifteen infants undergoing aortic coarctation repair. METHODS: After approval of the ethical committee and the relatives of the patients, 15 infants who had undergone thoracotomy were enrolled in the study. The patients received 0.5 ml·kg(-1) a bolus 0.25% bupivacaine with epinephrine 1 : 200 000 at T5-6 level after standard general anesthesia induction. Anesthesia depth with Index of Consciousness (IOC) and tissue oxygen saturation with cerebral (rSO2-C) and somatic thoracodorsal (rSO2-S) were monitored. Intraoperative hemodynamic and postoperative hemodynamic and pain scores were evaluated for 24 h after surgery. Face, Legs, Activity, Cry, Consolability (FLACC) score was utilized to measure postoperative pain in the intensive care unit. Rescue 0.05 mg·kg(-1) IV morphine was applied to patients in whom FLACC was >3. RESULTS: The median age of the patients was 4.5 (1-11) months, and the median intraoperative endtidal isoflurane concentration was 0.6% (0.3-0.8). The amount of remifentanil used intraoperatively was 4.5 (2.5-14) µg·kg(-) (1) ·h(-1). Intraoperative heart rate and blood pressure values significantly decreased compared with values detected at 5th, 10th, and 15th min after TPVB application, after incision prior and after cross-clamp (P < 0.01). The median time of first dose of morphine application after block was 320 (185-430) min. The median morphine consumption in 24 h was 0.16 (0.09-0.4) mg·kg(-1). The median length of postoperative intensive care unit and in-hospital stay times was 23 (1-67) h and 4 (1-10) days, respectively. CONCLUSION: We believe that TPVB, as part of a balanced anesthetic and analgesic regime, provides effective pain relief in patients undergoing aortic coarctation repair.

RESUMO

BACKGROUND AND AIM: We investigated the clinical outcome of early initiated peritoneal dialysis (PD) use in our newborn patients who underwent arterial switch operation (ASO) for transposition of the great arteries (TGA) and had routine intraoperative PD catheter implantation. We determined the risk factors for PD, factors associated with prolonged PD, morbidity, and mortality. The aim of the present study was to describe our experience of using PD in this patient cohort. MATERIALS AND METHODS: Eighty two patients who were diagnosed with TGA and TGA-ventricular septal defect (VSD) and who had undergone TGA correction operation in Baskent University, Istanbul Medical Research and Training Hospital between 2007 and 2012 were retrospectively investigated. All the patients were under 30 days old. PD catheters were routinely implanted intraoperatively at the end of the operation. PD was initiated in transient renal insufficiency. In the absence of oliguria and increased creatinine level, PD was established in the presence of one of the following: clinical signs of fluid overload, hyperkalemia (>5 mEq/L), persistent metabolic acidosis, lactate level above 8 mmol/L or low cardiac output syndrome. The patients were divided into two groups according to the need for postoperative PD (PD group and non-PD group). PD was initiated in 32 (39%) patients after the operation, whereas 50 (61%) patients did not need dialysis. The clinical outcomes and perioperative data of the two groups were compared. RESULTS: The demographics in the two groups were similar. Cardiopulmonary bypass time was longer in the PD group [non-PD group, 175.24 ± 32.39 min; PD group, 196.22 ± 44.04 min (p < 0.05)]. Coronary anomaly was found to be higher in the PD group [non-PD group, n = 2 patients (4.0%); PD group, n = 7 patients (21.9%); p < 0.05]. There was more need for PD in TGA + VSD patients [simple TGA patients, n = 14; TGA + VSD patients, n = 18 (p < 0.05)]. PD rate was higher in patients whose sterna were left open at the end of the operation (p < 0.05). The ventilator time [non-PD group, 4.04 ± 1.51 days; PD group, 8.12 ± 5.21 days (p < 0.01)], intensive care unit stay time [non-PD group, 7.98 ± 5.80 days; PD group, 15.93 ± 18.31 days (p < 0.01)], and hospital stay time were significantly longer in the PD group [non-PD group, 14.98 ± 10.14 days; PD group, 22.84 ± 20.87 days (p < 0.01)]. CONCLUSION: We advocate routine implantation of PD catheters to patients with TGA-VSD, coronary artery anomaly, and open sternum in which we have determined high rate of postoperative PD need.

RESUMO

The increased distance between the coronary ostium and the reimplantation site poses technical challenges in older patients with transposition of the great arteries (TGA) and complex coronary artery anomalies. In this report, we describe a technique for coronary artery reimplantation using a pedicle flap on the pulmonary artery (PA) to create a tunnel resulting in an extension of the coronary button.

RESUMO

OBJECTIVES: A new congenital heart surgery database (CKCV) with real-time online reporting function was recently developed in Turkey. All standard international parameters were used, but Aristotle Comprehensive Complexity score was modified. In this study, the first analysis of the CKCV Database is reported. METHODS: The CKCV Database included 2307 procedures from 12 centers between January 2018 and March 2020. All parameters, including 10 real-time online reports, which represent the number of centers, number and mortality rates of all procedures, number of extracorporeal membrane oxygenation (ECMO) and results, details of postoperative complications, age-group statistics, analysis for priority status, mean intensive care and hospital stay durations of the procedures, results of Aristotle Basic, Modified Aristotle Comprehensive (MACC) and Society of Thoracic Surgeons-European Association (STAT) Score Categories, comparison of centers were analyzed. RESULTS: Most common 10 procedures were ventricular septal defect (VSD) repair (n = 273), tetralogy of Fallot (TOF) repair (n = 243), atrial septal defect (ASD) repair (n = 181), complete AVSD repair (n = 95), cavopulmonary anastomosis (n = 81), systemic to pulmonary shunt (n = 79), modified Fontan (n = 71), subaortic resection, (n = 66) PA banding (n = 66), and arterial switch operation (n = 66). Cardiopulmonary bypass was used in 84.6% of the procedures. Overall mortality rate was 6.0%. A total of 618 major and 570 minor complications were observed in 333 and 412 patients, respectively. According to six MACC categories, number of the patients and mortality rates were I (293; 0.3%); II (713; 1.4%); III (601; 3.3%); IV (607; 12%); V (84; 35.7%); and VI (9; 55.6%), respectively. Analysis of five STAT Categories showed 0.7, 3.8, 5.4, 14.9, and 54.7% mortality rates. CONCLUSIONS: CKCV Database has a great potential for nationwide quality improvement studies. Users could instantly analyze and compare their results to national and international aggregate data using a real-time online reporting function. This is the first multicenter congenital database study in Turkey.
