RESUMEN
PURPOSE: Our aim in this study was to investigate the prenatal and postnatal prognosis of double outlet right ventricle (DORV) cases diagnosed prenatally by analyzing the outcomes based on the subtype. METHODS: This study is a retrospective chart review. Cases diagnosed with fetal DORV by prenatal ultrasound in the maternal-fetal medicine department of our hospital between 2014 and 2022 were included. Data on maternal characteristics, fetal echocardiographic features (type of DORV), pregnancy and neonatal outcomes (termination of pregnancy [TOP], intrauterine fetal death [IUD], neonatal death [NND], death in infancy (IND), survival) were collected and analyzed. RESULTS: Ninety-nine cases of prenatally diagnosed cases of DORV were included. The prenatal diagnosis was right in 97% of the liveborn fetuses. The cases were classified into subtypes, including transposition of great arteries (TGA), Fallot, ventricular septal defect (VSD), remote, and heterotaxy types. The cohort consisted of 32.3% TGA type, 19.1% fallot type, 11.1% VSD type, 2% remote type, and 35.3% heterotaxy type of DORV. An additional cardiac anomaly was observed in 87% and an extra-cardiac anomaly was observed in 54% of the cases. When we excluded the cases with heterotaxy type but without any chromosomal abnormality, additional genetic abnormalities were detected in 42% of the remaining cases. Outcome of pregnancy was livebirth in 68/99 (68.7%), IUFD in 5/99 (5.1%), and TOP in 26/99 (26.3%). Postnatal cardiac surgical repair was performed in 48 cases. Survival among livebirths was 39/68 (57.3%). Twenty-nine neonates or infants who had additional cardiac anomalies and/or genetic abnormalities died before any surgical intervention. The postoperative survival rate was 39/48 (81.2%). CONCLUSION: The prognosis in DORV depends on the anatomical subtype, the presence, and severity of associated anomalies. Survival increases in isolated cases without any additional structural or genetic anomalies.

To estimate if there is an association between partial AVSD with chromosomal abnormalities, cardiac and extracardiac malformations, and to report the outcomes of prenatally diagnosed AVSD in a large, contemporary cohort. This is a retrospective cohort study of 190 prenatally diagnosed fetal AVSD between 2014 and 2023. Type of AVSD (complete vs partial), additional cardiac findings, extracardiac findings, presence of a heterotaxy, results of prenatal karyotype, and pregnancy outcomes were documented and analyzed. A total of 190 cases of fetal AVSD were analyzed. Complete AVSDs comprised 141 (74.2%) of the cohort, while partial AVSDs comprised 49 (25.7%). Karyotype was completed in 131 cases, and in 98 (74.8%) cases chromosomal abnormalities were identified, with trisomy 21 being the most common (53/131, 40.5%). Complete AVSDs were associated with trisomy 21 (45.5%, p = 0.04), Isolated cases of complete AVSDs (p = 0.03). Partial AVSDs were associated with trisomy 18 (53.1%, p < 0.001). In cases of partial AVSDs with aneuploidies, 7 (70%) had an ostium primum defect and 20 (90.9%) of AV canal type VSD. Isolated partial AVSD had no clear association with aneuploidies. There were additional cardiac anomalies in 96 (50.5%) and extracardiac anomalies in 134 (70.5%) of the cohort. There were no differences between partial and complete AVSD in rate of additional cardiac and extracardiac anomalies. AVSD was part of a heterotaxy in 47 (24.7%) of cases, and heterotaxy was associated with complete AVSD in the majority of cases (43/47, 91.4%, p = 0.003). Fetal partial AVSDs are associated with trisomy 18. Fetal complete AVSDs, even isolated, are associated with trisomy 21. There were no differences in association of other aneuploidies, additional cardiac findings, or extracardiac anomalies between prenatally diagnosed complete AVSDs and partial AVSDs.

In individuals with a single ventricle undergoing evaluation before Fontan surgery, the presence of excessive pulmonary blood flow can contribute to increased pulmonary artery pressure, notably in those who had a Glenn procedure with antegrade pulmonary flow. 28 patients who had previously undergone Glenn anastomosis with antegrade pulmonary blood flow (APBF) and with elevated mean pulmonary artery (mPAP) pressure > 15 mmHg in diagnostic catheter angiography were included in the study. After addressing other anatomical factors that could affect pulmonary artery pressure, APBF was occluded with semi-compliant, Wedge or sizing balloons to measure pulmonary artery pressure accurately. 23 patients (82% of the cohort) advanced to Fontan completion. In this group, median mPAP dropped from 20.5 (IQR 19-22) mmHg to 13 (IQR 12-14) mmHg post-test (p < 0.001). Median PVR post-test was 1.8 (IQR 1.5-2.1) WU m2. SpO2 levels decreased from a median of 88% (IQR 86%-93%) pre-test to 80% (IQR 75%-84%) post-test (p < 0.001). In five patients, elevated mPAP post-test occlusion on diagnostic catheter angiography led to non-completion of Fontan circulation. In this group, median pre- and post-test mPAP were 23 mmHg (IQR 21.5-23.5) and 19 mmHg (IQR 18.5-20), respectively (p = 0.038). Median post-test PVR was 3.8 (IQR 3.6-4.5) WU m2. SpO2 levels decreased from a median of 79% (IQR 76%-81%) pre-test to 77% (IQR 73.5%-80%) post-test (p = 0.039). Our study presents a specialized approach for patients initially deemed unsuitable for Fontan due to elevated pulmonary artery pressures. We were able to successfully complete the Fontan procedure in the majority of these high-risk cases after temporary balloon occlusion test.

Despite advancements in postoperative outcomes after Fontan surgery, there remains a risk of suboptimal outcomes and significant morbidity in the early postoperative period. Anatomical obstructions in the Fontan pathway can lead to prolonged pleural effusion or ascites, cyanosis, and low cardiac output syndrome (LCOS). Transcatheter interventions offer an alternative to early re-surgery for treating these complications. Over a 13-year period, early catheter angiography, performed within 30 days post-index procedure, was administered to 41 patients, identifying anatomical issues that necessitated re-intervention in 39 cases. This led to transcatheter interventions in 37 (10.4%) of the 344 Fontan surgery patients. The median age was 4.8 years (IQR: 4-9.4), and the median weight was 16.5 kg (IQR: 15-25.2), with females comprising 51.4% (19/37) of this group. The primary indications for the procedures were persistent pleural effusion or ascites in 27 patients (66%), LCOS in 8 patients (20%), and cyanosis in 6 patients (14%). Among the 37 undergoing transcatheter intervention, 30 were treated solely with this method and discharged, three died in ICU follow-up, and four required early re-surgery. No procedural mortality was observed. Our findings demonstrate that transcatheter interventions, including stent implantation, balloon angioplasty, and fenestration dilation, are safe and effective in the early post-Fontan period. Therefore, they should be considered an integral part of the management strategy for this patient group.

OBJECTIVE: To assess the accuracy of prenatal echocardiography in defining pulmonary vasculature in pulmonary atresia with VSD (PAVSD). The second aim is to compare the perinatal and postnatal outcomes of different pulmonary blood supply types. STUDY DESIGN: The cases prenatally diagnosed with PAVSD between 2017 and 2022 in a single tertiary fetal medicine center were identified on the electronic database. Fetal echocardiography reports and images were reviewed retrospectively. Postnatal outcomes were acquired from the hospital records of relevant pediatric cardiology and cardiovascular surgery clinics. Fetal echocardiography results were compared with postnatal results. Perinatal and postnatal outcomes were compared between the different pulmonary vascular supply types. RESULTS: Among the 24 PAVSD cases, six were diagnosed with major aortopulmonary collateral arteries (MAPCA) dependent, eleven were diagnosed with ductus arteriosus (DA) dependent pulmonary supply, and seven were diagnosed with double pulmonary supply (MAPCA + DA) on prenatal echocardiography. Seventeen cases were live-born and have undergone postnatal investigations. Fetal echocardiography was 88.2% accurate about the type of pulmonary supply. The accuracy of fetal echocardiography regarding pulmonary vascular anatomy was 82.3%. Postoperative survival was 69.2%. Mortality before surgery and postoperative survival did not differ between pulmonary supply groups. Survival was impaired by the extracardiac anomalies. The need for early interventions was significantly higher in the DA group. CONCLUSION: Pulmonary vascularization in PAVSD can be defined precisely on fetal echocardiography. The source of pulmonary blood supply does not impact postnatal short-term outcomes significantly but it impacts the management. The associated anomalies highly contribute to postnatal mortality.

BACKGROUND: Pulmonary valve replacement is recommended in patients with repaired tetralogy of Fallot based on cardiac magnetic resonance imaging (MRI) criteria. This procedure is performed by surgical or transcatheter approaches. OBJECTIVE: We aimed to investigate the differences in preprocedural MRI characteristics (volume, function, strain) and morphology of the right ventricular outflow tract and branch pulmonary arteries in patients for whom surgical or transcatheter pulmonary valve replacement was planned. MATERIALS AND METHODS: Cardiac MRI of 166 patients with tetralogy of Fallot were analyzed. Of these, 36 patients for whom pulmonary valve replacement was planned were included. Magnetic resonance imaging characteristics, right ventricular outflow tract morphology, branch pulmonary artery flow distribution and diameter were compared between surgical and transcatheter groups. Spearman correlation and Kruskal-Wallis tests were performed. RESULTS: Circumferential and radial MRI strain for the right ventricle were lower in the surgical group (P=0.045 and P=0.046, respectively). The diameter of the left pulmonary artery was significantly lower (P=0.021) and branch pulmonary artery flow and diameter ratio were higher (P=0.044 and P = 0.002, respectively) in the transcatheter group. There was a significant correlation between right ventricular outflow tract morphology and right ventricular end-diastolic volume index and global circumferential and radial MRI strain (P=0.046, P=0.046 and P= 0.049, respectively). CONCLUSION: Preprocedural MRI strain, right-to-left pulmonary artery flow, diameter ratio and morphological features of the right ventricular outflow tract were significantly different between the two groups. A transcatheter approach may be recommended for patients with branch pulmonary artery stenosis, since both pulmonary valve replacement and branch pulmonary artery stenting can be performed in the same session.

Transcatheter closure of the tubular ducts remains the most challenging procedure, with higher complication rates than other types. This study evaluates the characteristics of transcatheter closure of tubular ducts with pulmonary hypertension. 73 patients with tubular ducts who underwent cardiac catheterization for transcatheter PDA closure were analyzed. The mean age and weight were 1.93 ± 2.68 years and 8.83 ± 6.14 kg, respectively. Transcatheter closure was attempted in 72 patients. Four cases (5.5%) were referred to surgery, while the procedure was completed in the remaining (94.5%). Amplatzer duct occluder (ADO) I or Cardiofix duct occluder (CDO) was the most commonly used devices. However, the use of Amplatzer vascular plug (AVP) II raised in recent years. The most common concern was aortic protrusion/stenosis in ADO I/CDO devices, but most regressed during follow-up. Iatrogenic coarctation of the aorta was observed in two with ADO I/CDO. Embolization of the device to the pulmonary artery was observed in three with CDO, AVP II, and AVP I. Significant left pulmonary artery stenosis requiring stenting developed in one after closure with an MVSDO device. Tubular ducts are highly associated with pulmonary arterial hypertension, and transcatheter closure of them is still challenging despite the developing device armamentarium. Although ADO I or similar devices are widely used, off-label devices are usually needed at increasing rates. The AVP II device is unsuitable for short tubular ducts but seems the best option for long ones.
RESUMEN
In patients with critical coarctation of the aorta, percutaneous balloon angioplasty and/or stent placement is usually performed via the femoral route. When femoral access is not suitable for intervention, the trans-axillary approach can be chosen as an alternative access. We hereby present the first case of a patient who had a successful percutaneous stent placement via trans-axillary access in our institution.

OBJECTIVE: The aim of this study is to define cardiac and extracardiac malformations in fetuses with heterotaxy syndrome and to determine perinatal and childhood prognosis. METHODS: In this retrospective study, fetuses diagnosed with heterotaxy syndrome on antenatal ultrasonography in a tertiary center between January 2014 and January 2021 were analyzed. Fetuses with heterotaxy syndrome were grouped as right atrial isomerism (RAI) and left atrial isomerism (LAI). RESULTS: A total of 62 fetuses, 32 (51.6%) with RAI and 30 (48.4%) with LAI, were included in the study. Extracardiac anomaly was detected in 25% of fetuses with RAI and 44% of fetuses with LAI (p = 0.13). Patients with univentricular repair had a higher childhood mortality than patients with biventricular repair (p = 0.031). The presence of conotruncal anomaly was an independent factor affecting mortality (HR = 5.09, CI 95% 1.09-23.71, p = 0.039). CONCLUSION: Hydrops fetalis, univentricular physiology and conotruncal anomalies are associated with poor outcomes in heterotaxy syndrome. The severity of the cardiac malformation is the main determinant of the outcomes. The presence of extracardiac malformations is associated with increased morbidity and mortality.

Pulmonary atresia with ventricular septal defect is a complex congenital cardiac anomaly. The blood is supplied to the lungs through a patent ductus arteriosus, a major aortopulmonary collateral artery, or in very rare cases from a coronary artery-pulmonary artery fistula. We present two cases with coronary artery-pulmonary artery fistula which underwent surgical intervention. In our first patient, the main pulmonary artery was supplied from the left main coronary artery. In the second patient, the right pulmonary artery originated from the left main coronary artery and continued to the right lung posteriorly to the aorta, while the left pulmonary artery originated from the patent ductus arteriosus. The difference in our cases is that the coronary artery pulmonary artery fistulas behave like major aortopulmonary collateral arteries originating from the coronary arteries. These fistulas were the main source of pulmonary blood flow.

Aneurysms of the ascending aorta are frequently found in patients with a bicuspid aortic valve (BAV). This study assessed the risk factors of ascending aortic aneurysms and aortic elasticity in children with BAV. The study included 66 patients with no history of transcatheter intervention or surgical procedure who had been diagnosed with isolated BAV. Echocardiographic, blood pressure, and pulse measurements were obtained for all patients. The BAVs were classified as described by Sievers et al. (J Thorac Cardiovasc Surg 133:1226-1233, 2007), and aortic elasticity parameters were calculated using various formulas. The patients were divided into groups with and without cusp fusion, aortic stenosis (AS), aortic regurgitation (AR), or mixed lesions; the groups were then compared. The mean patient age was 10.43 ± 3.91 years; 15%he patients had no AS or AR, 33% had both AS and AR, 17% had AS alone, and 35% had AR alone. The most common type of BAV was type 5, and the ascending aorta z-scores were higher in children with mixed lesions and without a cusp fusion. Aortic distensibility (AD) was significantly higher, and the stiffness index was significantly lower, in patients with an ascending aorta z-score > 4. The ascending aortic z-scores were higher in the no-fusion and mixed lesion (AS + AR) groups, especially those originating from post-stenotic dilation due to AS. The AD was increased in patients with an ascending aorta z-score > 4. Patients should thus be monitored closely for dissection risk, and preventive medical treatment should be started early in those with AS without cusp fusion.

BACKGROUND: Although percutaneous closure of patent ductus arteriosus is an established safe procedure, protrusion of the device to descending aorta may occur in various degrees during these procedures, especially in small infants. The aim of our study is to evaluate the benefits of balloon-assisted device releasing technique in the era of preventing device protrusion and conditions related to protrusion. METHODS: One hundred and fifty-five infants, who underwent patent ductus arteriosus closure with Amplatzer duct occluder I device between January, 2012 and December, 2018, were retrospectively analysed. Balloon-assisted device releasing technique was used in 20 cases (group 1, 12.9%), between January, 2015 and December, 2018. Procedures in which the technique had been used were compared with the remaining ones (group 2, 87.1%, n = 135) with regard to device stabilisation, aortic disc protrusion to the aorta, iatrogenic coarctation, and device embolisation. RESULTS: There was no significant difference by means of gender, age, weight, and the ductal diameter, whereas the average mean pulmonary artery pressure was significantly higher in group 1. Device protrusion and related complications were significantly higher in group 2; thus, additional catheterisations or surgical interventions were required, while no additional intervention was required in group 1. CONCLUSION: The balloon-assisted device releasing technique provides a good device stabilisation and prevents protrusion of the device and related complications during percutaneous patent ductus arteriosus closure in selected cases.

INTRODUCTION: The CeraFlexTM PDA occluder is a new flexible device with a unique delivery system that may be beneficial with regard to not changing the device position after releasing. We prospectively evaluate the efficacy of the device and also the device behaviour patterns during release. METHODS: The study included 21 patients. Their median age was 1.2 years (from 6 months to 28 years) and weight was 9.6 kg (from 5.4 to 82 kg). All of the ducts were conical except one atypical ductus. Median ductal diameter at the pulmonary end was 3.8 mm (from 2.2 to 8.2 mm). The ductus was closed using an antegrade approach, but special attention was paid to the patterns of device behaviour during and just after releasing. RESULTS: Three different modes of device behaviour were observed during and just after releasing: (1) Neither difficulty nor change of position in 13 patients (62%), (2) a little difficulty in releasing but no change of position in 6 (29%), and (3) change of the device position in 2 (9%). There was no residual shunt on the next day except in one patient, in whom late device embolisation occurred. The device was retrieved and another, bigger device implanted. CONCLUSION: The CeraFlexTM PDA occlude device seems to be safe and efficacious for patent ductus arteriosus closure. Its unique delivery system generally fixes the device in a stable position that does not change after release (91%). Minor difficulty in releasing is not uncommon; however, the major disadvantage is the need for larger sheaths for delivery.

OBJECTIVE: To determine the short- and medium-term outcomes of ductal stenting (DS) in patients with functionally univentricular hearts (FUHs) and ductal-dependent pulmonary blood flow. BACKGROUND: Several studies have evaluated the outcomes of DS in a limited number of patients with FUHs. Nonetheless, there is still no consensus regarding the indications for this procedure, and no appropriate patient selection criteria have been devised. METHODS: From 2005 to 2015, cardiac catheterization for DS was performed in 68 patients with FUHs. Of these patients, 49 had single source pulmonary blood flow from ductus arteriosus. Procedural and follow-up data were evaluated. RESULTS: The median weight of the patients was 3.6 kg (2.3-6.8 kg), and the median age was 26 days (3 days-8 months). The technical success rate of the procedure was 95% (65 of 68 patients). Mean oxygen saturation increased from 70% ± 7.6% to 87% ± 4.6% (P < 0.0001). Among patients in whom DS was successful, 55 (84.6%) were bridged to a Glenn procedure after a median of 9.1 months (6.4-14 months), and 41 (63%) were successfully bridged to a Glenn procedure without additional interventions. Of the 16 patients with preexisting mild pulmonary artery stenosis, five required a surgical shunt due to progressive branch pulmonary artery stenosis, while nine were bridged to a Glenn operation without shunt placement. Five (7.3%) patients died, including patients who were sent to surgery. CONCLUSION: DS is a reasonable and effective alternative to surgical shunt placement as a first-stage palliative procedure in patients with FUHs. © 2016 Wiley Periodicals, Inc.

We aimed to assess early and midterm outcomes of balloon valvuloplasty (BVP) procedure in patients with critical pulmonary stenosis (CPS) and to describe the predictors of the need for additional pulmonary flow and reintervention in this subgroup of patients. From 2005 to 2014, 56 neonates were diagnosed with CPS and were included in this study. All echocardiographic, catheterization and angiographic data obtained prior to the initial BVP and at follow-up were reviewed. BVP was successful in 55 neonates (98 %). Twenty-one neonates needed pulmonary blood flow augmentation after BVP (38 %). Ductal stenting (DS) was performed in 20. The patients' mean tricuspid valve (TV) annulus diameter was 10.4 ± 2 mm, and the Z score was -1.29 ± 1 (-3.7 to 0.78). The mean pulmonary valve (PV) annulus diameter was 6 ± 0.9 mm, and the Z score was -1.74 ± 1 (-4.34 to 0.05). A transcatheter or surgical reintervention was performed in 11 patients. A TV Z score < -1.93 SD predicted the need for pulmonary blood flow augmentation after a successful BVP, with a sensitivity of 63.2% and a specificity of 84.4%. A PV Z score < -1.69 SD predicted the need for pulmonary flow augmentation, with a sensitivity of 74 %. The presence of bipartite RV was found to be a significant predictor of the need for reintervention (odds ratio 9.6). Our study showed the excellent immediate outcomes of BPV and DS in a pure cohort of patients with CPS. Prophylactic DS in selected cases seems reasonable and safe.

We aim to assess the safety, feasibility and efficacy of the new Nit-Occlud ASD-R (NOASD-R) device. From 2014 to 2015, transcatheter closure of atrial septal defect (ASD) using the NOASD-R was performed in 30 consecutive patients. The standard deployment technique as the left upper pulmonary vein approach was used in 25 patients. Right upper pulmonary vein approach was required in five. The median age was 6 years (range 3.5-60 years), and median weight was 21.5 kg (14-79 kg). Implantation was successful in all patients. The median size of devices was 16 mm (12.0-26.0 mm). The mean device size/2D defect diameter ratio was 1.26 ± 0.09 (1.12-1.40). The mean device size/color flow diameter ratio was 1.07 ± 0.06 (range 1.0-1.22). Releasing problem was encountered in three patients. A device-related erosion on the day after the closure was observed in one patient. No further device-related complication (erosion, embolization or dislodgement of the device) was encountered in a median follow-up period of 10 months (range 2-14 months). Complete occlusion has occurred in all at follow-up. NOASD-R is a feasible and effective device for use in the transcatheter occlusion of moderate to large secundum ASDs in selected patients. The occurrence of the erosion on the right atrial roof may be due to the high localization of the device and the larger size of the right disk.

A descending aorta to vertebral venous plexus fistula is an extremely rare form of arteriovenous fistula. A 10-month-old infant was referred to the hospital for evaluation of a murmur. On examination, a continuous murmur was heard in the entire back. Transthoracic echocardiography revealed left heart chamber dilatation in the presence of preserved left ventricle systolic function. Computerized tomography angiography with 3-dimensional reconstruction, and lateral projection aortography revealed a descending aorta-vertebral venous plexus fistula measuring 4.8 mm in the aortic orifice. The fistula was embolized using an Amplatzer Vascular Plug 2.

OBJECTIVE: To analyze the prenatal and postnatal outcomes of fetuses with d-TGA and to determine whether prenatal echocardiography may predict postnatal urgent BAS. STUDY DESIGN: A retrospective study of fetuses with d-TGA, for which fetal echocardiography was performed at our tertiary hospital from January 2018 to May 2023. We assessed the appearance of the septum primum and the FO flap in the four-chamber view as to whether the FO had a restrictive appearance during measurement of the diameter of the FO at its maximal angle to the attachment point. Color Doppler was used to detect VSDs and measure its diameter both in the four-chamber view and when visualizing the outlets of the great arteries in the sagittal section of the heart. RESULTS: During the study period, 64 fetuses were diagnosed with d-TGA, which was also confirmed postnatally. Of these, 16 fetuses were excluded due to additional cardiac anomalies or the inability to reach the mother. In total, 48 cases were included in this series. In our study, the FO diameter was significantly decreased in the urgent BAS group, compared with the fetuses without urgent BAS (5.1 mm vs 6.3 mm). A cut off of 6 mm for the FO diameter (sensitivity, 73.3 %; specificity, 72.2 %; area under the curve [AUC], 0.764) and 3.2 mm for the VSD diameter (sensitivity, 75 %; specificity, 75 %; AUC, 0.728) suggested urgent BAS. CONCLUSION: Prenatal echocardiography performed after 37 weeks of gestation in fetuses with d-TGA provides valuable information to estimate the need for postnatal urgent BAS that would prevent immediate life-threatening complications.
RESUMEN
Background: This study aimed to investigate the safety and efficacy of transverse aortic arch stenting and evaluate the course of hypertension and the act of arch stenting on systemic hypertension. Methods: The transverse aortic arch stenting procedures between January 2007 and May 2023 were retrospectively analyzed. Detailed procedure information, technical aspects, pressure measurements, angiographic data, balloons and stents used, complications, and immediate results were examined. Early and mid-term results were assessed. Results: Eighteen patients (10 males and 8 females; mean age: 14.5±5.3 years; range, 4 to 23 years) were included in the study, all of whom were hypertensive before the procedure. The mean weight was 56.8±19.6 kg. In seven patients, the stent struts had to be dilated due to the stent causing jailing at the entrance of nearby arch vessels. After stenting, there was a significant increase in arch diameter and a decrease in ascending aorta pressure and the pressure gradient across the aorta. There were no early mortality or major complications. Late migration of the stent was observed in one patient. Three patients became normotensive immediately after the intervention, and five became drug-free during the follow-up. The requirement for dual antihypertensive therapy was significantly reduced. Conclusion: Residual transverse arch lesions may contribute to the persistence of systemic hypertension after coarctation treatment. Transverse arch stent implantation can be performed safely with favorable outcomes, facilitating better blood pressure control. However, it should be noted that these patients remain at risk for lifelong hypertension and should be closely monitored in this regard.
RESUMEN
BACKGROUND: We sought to investigate the safety, efficacy, and follow-up results of percutaneous patent ductus arteriosus (PDA) closure using the novel Cardi-O-Fix duct occluder (CDO), a device similar to but less expensive than the Amplatzer duct occluder (ADO). We also aimed to compare these two devices in terms of results. METHODS: Between March 2005 and May 2012, 167 patients diagnosed with moderate-to-large PDA underwent transcatheter closure. ADO was used in 56 (33.5%) patients with a mean age of 8.1 ± 11.9 years (3.6 months-56 years), whereas CDO was used in 111 (66.5%) patients with a mean age of 12.6 ± 14.6 years (4.8 months-63 years). RESULTS: The narrowest PDA diameter, the used device diameter, procedure time, fluoroscopy time, and residual shunt rates were similar between the two groups. Procedural success rate was 100% in both groups. Although the residual shunt rate was higher in the CDO group immediately after the procedure, the difference was not statistically significant (12.6 vs. 8.9%; P = 0.3). There was no statistically significant difference between groups at discharge and during follow-up. No deaths occurred in any of the groups, and there were no differences in complication rates during the short- and mid-term follow-up periods (CDO 7/111 vs. ADO 5/56; P = 0.5 π). CONCLUSION: The CDO can be used for PDA closure because of its safety, effectiveness, and simplicity in use. It is available in bigger sizes and can be used in patients with large defects. According to our short- and mid-term findings, the results it yields are similar to those of the ADO; thus, it may be the preferred choice owing to its low cost and large size variability.
