RESUMO
Following current practice, pediatric patients with treated congenital coronary malformations or acquired coronary disease undergo Cardio-Pulmonary Exercise Test (CPET), stress Echocardiography and Electrocardiography (sEcho, sEKG), and Coronary Angiography (CA). Stress cMRI can assess cardiac function, myocardial viability, and stress/rest perfusion deficit-without radiation exposure, general anesthesia, and hospitalization-in a single non-invasive exam. The aim of our pilot study is to assess the feasibility and diagnostic accuracy of Dobutamine stress cMRI compared to the current procedures (sEcho, CPET, CA). The prospective study is focused on pediatric patients, at risk for or with previously diagnosed coronary artery disease: d-looped TGA after arterial Switch, Kawasaki disease, and anomalous origin of left coronary artery from pulmonary artery (ALCAPA) after coronary artery reimplantation. We have compared the results of MRI coronary angiography, and Dobutamine stress cMRI with traditional tests. All these diagnostic exams were acquired in a timeframe of 3 month, in a blinded fashion. All the 13 patients (age: 12 ± 2 years, median 12,7 y) recruited, completed the study without major adverse events. The mean heart rate-pressure product was 25,120 ± 5110 bpm x mm Hg. The target heart rate of 85% of the maximal theoretical was reached by 10 (77%) patients. The comparison between cardiac MRI coronarography versus the gold standard Coronary Angiography to identify the patency of the origin and the proximal pathway of the coronary arteries shows a sensitivity of 100% (confidence interval: 2,5-100%), specificity 92% (confidence interval: 64-100%). The stress test was well tolerated for the 77% of the patients and completed by the totality of patients (Table 3). Three patients (23%) had mild symptoms: nausea, vomiting, or general discomfort. In pediatric patients with a potential or definite diagnosis of coronary artery disease, stress cMRI combines an effective assessment of proximal coronary arteries anatomy with cardiac function, myocardial perfusion, and viability in a single examination. Stress cMRI can be proposed as alternative, standalone test.

We present a case of aortopulmonary window in which the diagnosis of anomalous left coronary artery originating from pulmonary artery was made intra-operatively even if the coronary arteries anatomy was correctly studied pre-operatively with echocardiography. No evidence of coronary anomalies or indirect sings of coronary anomalies has been noted. Should we improve our pre-operative diagnostic accuracy and how?

IntroductionPulmonary atresia, ventricular septal defect, major aorto-pulmonary collateral arteries, and pulmonary arteries hypoplasia are rare and complex congenital defects that require early interventions to relieve cyanosis and enhance the growth of native pulmonary arteries. The treatment of these patients is still controversial. Surgical techniques require cardiopulmonary bypass which is poorly tolerated by small infants. Percutaneous techniques such as radiofrequency perforation can be challenging. The hybrid technique consists of perventricular stenting of the right ventricle outflow tract through medial sternotomy, to restore native pulmonary flow. METHODS: We retrospectively reviewed the cardiovascular database of our centre in order to analyse our experience in hybrid procedure. We detected six patients who underwent hybrid first approach between November 2007 and December 2015. We report our early results and mid-term outcomes. RESULTS: Median age at the procedure was 26 days, median weight was 3150 g, and median Nakata index was 52 mm2/m2. All procedures were successful except for one: this patient underwent a surgical shunt. No immediate and early deaths or major complications occurred and oxygen saturation levels increased in all the patients. Patients were followed up for a period of 12-103 months, and four of them underwent a procedure of unifocalisation at the mean age of 12.5 months. CONCLUSIONS: We reported data from the largest series of patients who underwent this hybrid procedure. Our experience demonstrated encouraging results to expand the use of this approach to bridge high-risk patients with diminutive pulmonary arteries to a second step of surgical repair.

INTRODUCTION: Neonates with D-transposition of the great arteries (dTGA) may die at birth because of the inadequate intracardiac mixing due to a misdiagnosed restrictive foramen ovale. We reviewed our experience in echocardiographic assessment and perinatal management of fetuses with dTGA searching for new features that may predict the need for urgent balloon atrial septostomy (BAS) immediately after birth. PATIENTS AND METHODS: We included fetuses diagnosed with dTGA between January 2000 and December 2014. We assessed pre- and postnatal appearance of the foramen ovale, ductus arteriosus and pulmonary veins. Both the diagnostic findings at the time of last prenatal echocardiogram and those findings deriving from a retrospective reevaluation of stored videos were considered. BAS was defined as urgent if performed in neonates with restrictive foramen ovale and severe hypoxemia. RESULTS: We reviewed 40 fetuses with dTGA. 20/40 fetuses received urgent BAS at birth. Not only the restrictive but also the hypermobile and the redundant appearance of the foramen ovale was significantly associated with urgent BAS (p < 0.0001, p = 0.002 and p = 0.0001, respectively). CONCLUSIONS: Prenatal evaluation of the foramen ovale appearance in fetuses with dTGA is still challenging. Based on our experience, also the redundant foramen ovale appearance may need urgent BAS at birth.

BACKGROUND: Fluoroscopic catheter ablation of cardiac arrhythmias in pediatric patients exposes the patients to the potential risk of radiation considering the sensitivity of this population and its longer life expectancy. We evaluated the feasibility, safety, and efficacy of accessory pathway (AP) ablation guided by CARTO3 electroanatomic mapping (EAM) system with both cryoenergy and radiofrequency (RF) energy in order to avoid x-ray exposure in pediatric patients. METHODS: We included 44 patients (mean age: 13.1 ± 3.3 years); nine of 44 presented concealed AP. An electrophysiological study with a three-dimensional EAM reconstruction was performed in every patient with a venous transfemoral direct right atrium approach or an arterial transfemoral retrograde approach to reach the mitral annulus. In two patients with left-sided AP, the ablation was performed via a patent foramen ovale. RESULTS: A total of 47 APs were present, left sided in 45% (21/47) of cases (15 lateral, one anterior, three posteroseptal, and two posterolateral) and right sided in 55% (26/47; one anterior, three anterolateral, one posterolateral, three lateral, five para-Hisian, 12 posteroseptal, and one anteroseptal). Ablation without the use of fluoroscopy was successfully performed in every patient (33 with RF and in 11 with cryoenergy). No complication occurred. At a mean follow-up of 16.0 ± 11.7 months, we observed seven recurrences, three of them successfully re-ablated without fluoroscopy. In one case cryoablation of a para-Hisian AP was ineffective in the long term. CONCLUSIONS: Three-dimensional EAM allowed a safe and effective fluoroless AP ablation procedure in a pediatric population both with RF and cryoenergy.

BACKGROUND: Anatomical considerations and risks related to x-ray exposure make atrioventricular nodal reentrant tachycardia (AVNRT) ablation in pediatric patients a concerning procedure. We aimed to evaluate the feasibility, safety, and efficacy of performing fluoroless slow-pathway cryoablation guided by the electroanatomic (EA) mapping in children and adolescents. METHODS: Twenty-one consecutive patients (mean age 13.5 ± 2.4 years) symptomatic for AVNRT were prospectively enrolled to right atrium EA mapping and electrophysiological study prior to cryoablation. Cryoablation was guided by slow-pathway potential and performed using a 4-mm-tip catheter. RESULTS: Sustained slow-fast AVNRT was inducible in all the patients with a dual AV nodal physiology in 95%. Acute success was achieved in 100% of the patients with a median of two cryo-applications. Fluoroless ablation was feasible in 19 patients, while in two subjects 50 seconds and 45 seconds of x-ray were needed due to difficult progression of the catheters along the venous system. After a mean follow-up of 25 months, AVNRT recurred in five patients. All the recurrences were successfully treated with a second procedure. In three patients, a fluoroless cryoablation with a 6-mm-tip catheter was successfully performed, while in the remaining two patients, a single pulse of 60 seconds of radiofrequency energy was applied under fluoroscopic monitoring. No complications occurred. CONCLUSIONS: Combination of EA mapping systems and cryoablation may allow to perform fluoroless slow-pathway ablation for AVNRT in children and adolescents in the majority of patients. Fluoroless slow-pathway cryoablation showed a high efficacy and safety comparable to conventional fluoroscopy guided procedures.

BACKGROUND: Pulmonary atresia and intact ventricular septum is a complex congenital heart disease with great morphological variability. Approximately two-thirds of patients may be suitable for transcatheter pulmonary valvotomy. We reviewed our experience in the use of two different percutaneous approaches to evaluate the impact on fluoroscopy time and morbidity of a new technique to perform transcatheter radiofrequency perforation and valvotomy in newborns with pulmonary atresia and intact ventricular septum. METHODS AND RESULTS: In all, 31 patients underwent radiofrequency perforation of the pulmonary valve. The first 14 infants were treated using a 5 French Judkins right coronary catheter, which was manoeuvred directly underneath the atretic pulmonary valve (Group A). The others were treated using a telescopic system consisting of Northstar Lumax Flex and White Lumax Guiding Catheters (Cook; Group B). In both groups, after radiofrequency perforation of the pulmonary valve, a 0.014-inch superfloppy guidewire was advanced into the descending aorta and balloon dilations were performed. Required fluoroscopy time was significantly lower in Group B (48.5 ± 28.1 versus 24.9 ± 14.4 minutes, respectively; p < 0.01). A higher incidence of unfavourable events including the need for early surgery was found in Group A. CONCLUSION: In our experience, telescopic catheter proved to be a valid option able to decrease the fluoroscopy time of percutaneous radiofrequency perforation of pulmonary valve and consequently patients' exposure to procedure-related risks.

OBJECTIVES: To describe our experience in the management of coronary artery anomalies both in an adult and in a paediatric population and to compare the two groups for finding out differences in terms of angiographic incidence and treatment. PATIENTS AND METHODS: Databases at the Department of Cardiology of San Martino Adult's Hospital and of Gaslini Children's Hospital were searched for all patients with a diagnosis of coronary artery anomaly who underwent coronary angiography between 1994 and 2006. RESULTS: Coronary anomalies were diagnosed in 76 (1%) adult patients. Anomalous left circumflex artery was the commonest coronary anomaly (25%). Anomalous left coronary artery from pulmonary artery and myocardial bridges were the only anomalies responsible for angina-like symptoms. No patients except the one with anomalous left coronary artery from pulmonary artery needed surgical intervention. In the paediatric population, we found 28 (0.9%) patients with coronary anomalies. Anomalous left coronary artery from pulmonary artery was the most common anomaly (48%) and always required emergency surgical treatment; in addition there were two patients with stenosis of the left main coronary artery. CONCLUSION: Coronary artery anomalies may be associated with very acute, even life-threatening symptoms in children, whereas they are usually clinically silent and detected by accident on coronary angiography in adults. Recognition of coronary artery anomalies enables early treatment or close follow-up in children, whereas it could be useful in case of cardiac surgery in adults.

Acquired pulmonary vein occlusion is a rare complication of surgical correction of complex congenital heart diseases. Associated vascular remodeling of arterial and venous vessels includes medial thickening, intimal fibrosis, and progressive development of aorto-pulmonary collaterals. The consequent pulmonary perfusion changes impact more importantly on a low pressure circulation such as the Fontan circuit. The management of these patients is still controversial. We describe this condition in two patients with single ventricle who underwent staged cavopulmonary connection. In both cases, we found acquired occlusion of one pulmonary vein, poor antegrade flow in the involved hypoplastic pulmonary arteries due to a widespread thin collateral circulation producing a backward washout of unopacified blood flow with competitive mechanism. Percutaneous embolization of a segmental pulmonary artery was performed with restoration of a more homogeneous perfusion of both main pulmonary arteries. Extracardiac total cavopulmonary connection was successfully performed a few months later in both patients.

Objectives: This study aims to determine a combination of third-trimester echocardiographic parameters for improving the prenatal prediction of coarctation of the aorta (CoA) after birth. Methods: We included all cases of suspected CoA during fetal echocardiography performed in the second and/or third trimester of pregnancy at Gaslini Children's Hospital between January 2010 and December 2020. The last prenatal ultrasound evaluation was reviewed considering most of the echocardiographic criteria were already published for prenatal CoA diagnosis. Associated minor cardiac anomalies, such as a ventricular septal defect, persistent left superior vena cava (PLSCV), and redundant foramen ovale (FO) membrane, as well as postnatal outcomes, were reported. Initial perinatal management was defined based on the risk stratification of CoA during prenatal echocardiography. Neonates were divided into two groups depending on the presence or absence of CoA after birth. Results: A total of 91 fetuses with CoA suspicion were selected, of which 27 (30%) were confirmed with CoA after birth and underwent surgical repair. All cardiac parameters except redundant FO membrane and PLSCV showed a significant correlation with CoA. Statistical analysis confirmed that cardiovascular disproportion with right predominance carries an increased risk for occurrence of CoA, especially if already evident during the ultrasound evaluation in the second trimester. Aortic valve (AV) z-score and distal transverse aortic arch (TAA) z-score resulted as the best predictors of CoA after birth. The best cutoff point for CoA discrimination with ROC analysis was an AV z-score of -1.25 and a distal TAA z-score of -0.37. A total of 46% of those without CoA were diagnosed with a cardiac defect, which was not diagnosed in utero, pulmonary hypertension, or a genetic syndrome. Conclusion: The current criteria for diagnosing CoA in utero allow accurate diagnosis of most severe cases but the rate of false positives remains relatively high for milder cases. A combination of anatomic and functional echocardiographic parameters might be used in stratifying the risk of CoA. We proposed the AV and the TAA diameter z-scores as the best predictors of CoA after birth. In addition, neonates without CoA deserve proper monitoring at birth because prenatal evidence of a significant cardiovascular discrepancy between the right and left cardiac structures has an inherent risk for additional morbidity postnatally.
RESUMO
Cardiac involvement in multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus-19 disease is often observed with a high risk of heart failure. The aim is to describe cardiovascular involvement, management and early outcome in MIS-C by comparing cardiovascular manifestations in children younger and older than 6 years old. This retrospective observational study included 25 children with MIS-C, admitted to a single pediatric center between March 2020 and September 2021. The median age was 5 years (13 patients under 6 years and 12 over 6 years); coronary artery abnormalities were observed in 77% of preschoolers, with small and medium aneurysms in half of the cases and two cases of mild ventricular dysfunction. School-age children presented myopericardial involvement with mild to moderate ventricular dysfunction in 67% of cases, and two cases of transient coronary dilatation. There was a significant NT-pro-BNP and inflammatory markers increase in 25 of the patients, and mild elevation of troponin I in 9. All patients were treated with intravenous immunoglobulin and corticosteroids, and 8 with anakinra. None of the patients needed inotropes or intensive care unit admission. Our study shows the frequent cardiovascular involvement in MIS-C with a peculiar distribution, according to different age group: coronary artery anomalies were more frequent in the younger group, and myopericardial disease in the older one. A prompt multitarget, anti-inflammatory therapy could probably contribute to a favorable outcome.
RESUMO
BACKGROUND: A multidisciplinary study group involving physicians and jurists was established to review and approve an informed consent about the most frequent interventional procedures for congenital heart diseases. METHODS: The authors worked together with representatives of the Italian Society of Pediatric Cardiology and Congenital Heart Disease (SICP) Council and Jurist's expert in the field of health case-law. The final draft was shared with the major Italian centers involved in congenital interventional procedures and with AICCA, the Italian Patients Association of Congenital Heart Diseases - Adults and Children. RESULTS: At the end of this review process, a final informed consent form was developed for the most frequent procedures performed in our catheterization laboratories. All of them consist of two parts: a general statement and a procedure-related one. CONCLUSIONS: The work performed by this multidisciplinary study group, under the supervision of the SICP, resulted in a new dedicated informed consent about interventional procedures in the field of congenital cardiology, taking into account the new legal requests. This informed consent is intended to be both a document that can be used as such and a document from which to derive a specific document for each center. We believe that using similar informed consents in all Congenital Heart Disease Centers or at least have informed consents all inspired by the same setting, could be a further improvement in taking care of the patients and their families.

BACKGROUND: The sternal lift by Vacuum Bell (VB) is effective, as largely demonstrated by its intraoperative use during surgical procedure to elevate the sternum during the Nuss procedure routinely. Indeed, the thoracic remodelling during VB application is comparable to post-surgical scenario, and suitable to compare cardiovascular parameters of the two different thoracic configurations immediately. OBJECTIVE: We would quantify and correlate preoperative parameters which determine the severity of the pectus excavatum (PE), and the cardiovascular effects at the baseline. Than we would assess the cardiovascular changes during VB positioning, mimicking the immediate, temporary effect of Pectus-correction. MATERIALS AND METHODS: We included 26 consecutive patients (mean age is 13,3 +/- 2,2 years) symptomatic and non, with a previous clinical diagnosis of PE. CMR was performed before and during application of VB, using the same imaging protocol. In both conditions, we measured thoracic indexes, and cardiac function as well as flow through main vessels. RESULTS: Mean expiratory Haller Index (HI) was 5,4 (+/-1,4 SD; normal <3). During VB application, all patients showed improvement in the main morphologic parameters of the thorax (mean expiratory HI = 4,7 (+/-1,6 SD, delta -13%, P = 0,01). During VB application, a minimal but not significant increase of Right Ventricle End Diastolic Volume (RVEDVi) (delta +4,6%, P = 0,12), and Right Ventricle Ejection Fraction (RVEF) (delta +1,2%, P = 0,2) was observed. CONCLUSION: In adolescents affected by PE, cardiacMRI (CMR) demonstrates normal values of biventricular volume and systolic function. During VB application, beside significative improvements in chest wall anatomy, CMR shows a minimal positive variation in right ventricle volume and function. A minority of patients showed some degree of diastolic dysfunction at baseline, unchanged after VB application, with possible correlation between valve inflow and sternal impingement.

Objective: The aim of the study is to describe a delivery room intensive care unit (DRICU) model and evaluate its effectiveness in preventing morbidity and mortality in high-risk newborns. Design: This retrospective case series includes all DRICU procedures performed from 2016 to 2020. Setting: Gaslini Children's Hospital is a major pediatric tertiary care center where high-risk pregnancies are centralized. The Neonatal and Pediatric Intensive Care Unit admits every year about 100 high-risk newborns. Patients: The selected patients are newborns at risk of critical conditions immediately after birth for respiratory or cardiovascular congenital disorders. Interventions: The perinatal plan is defined by the multidisciplinary team of Fetal and Perinatal Medicine. The DRICU procedure provides highly specialized care through a protocol that includes logistics, personnel, equipment, and clinical pathways. Main Outcome Measures: The primary outcome is the prevention of acute complications and mortality in the delivery room and early neonatal period. Results: From 2016 to 2020, 40 DRICU procedures were performed. The main prenatal diagnoses included congenital heart disease with a high risk of life-threatening events immediately after birth (38%), congenital diaphragmatic hernia (35%), and fetal hydrops/hydrothorax (23%). Mean gestational age was 35.9 weeks (range: 31-39), and mean birth weight was 2,740 grams (range: 1,480-3,920). DRICU assistance completed in all patients by neonatal intensivists included tracheal intubation and arterial and central venous cannulation; complex procedures such as ex-utero intrapartum technique and extracorporeal membrane oxygenation cannulation are described. No deaths nor severe acute complications occurred in the delivery room or in the immediate postnatal period. Conclusions: The outcome in critical newborns is potentially affected by planned assistance strategies and specialized competencies through the implementation of a DRICU protocol.
RESUMO
BACKGROUND: Congenital and acquired airway anomalies represent a relatively common albeit diagnostic and therapeutic challenge. Obtaining maximum definition of the abnormality is imperative prior to attempting surgical procedure because some tracheal lesions have a significant risk of mortality. Are Tracheobronchography (TBG) and Tracheobronchofluoroscopy (TBF) valuable or obsolete tecniques? METHODS: We retrospectively reviewed all the diagnostic and interventional TBG-TBF requested by the multidisciplinary conference, during the last 10 years in a tertiary care hospital exclusively dedicated to pediatric patients. RESULTS: A total of 268 procedures performed in 60 pediatric patients (68% male, mean age 4,8 years), were reviewed. 41 diagnostic TBG-TBF were performed in a group of 34 patients with excellent result, without complications. A total of 175 procedures of tracheobronchoplasty guided by TBG-TBF were completed in a group of 25 patients. Seven bioabsorbable self-expanding stents were placed in the airway of 6 children. CONCLUSIONS: Diagnostic TBG and TBF are still irreplaceable tools to evaluate pediatric airway disease, with many advantages over the newest imaging techniques. Interventional procedures of pediatric airways under the guide of TBGTBF represent safe and effective treatment options in selected patients, with positive clinical impact.
RESUMO
BACKGROUND: The Cocoon septal occluder (CSO) is a new generation double disk occluder device for catheter closure of the secundum atrial septal defect (ASD). Initial clinical evaluations with the use of this device have shown quite satisfactory results but large follow-up studies are missing. In this international multicenter study, we present procedural and follow-up data from 4008 patients with secundum ASD who underwent catheter closure with the use of CSO. METHODS: The study cohort consisted of 1853 pediatric and 2155 adult patients with secundum ASD treated with the CSO. Patients were enrolled retrospectively from 11 international centers and were followed for a mean period of 43 months (range 12-84 months), postprocedural. Clinical, electrocardiographic, echocardiographic, procedural, and follow-up data were collected from each collaborating hospital. RESULTS: The CSO was permanently implanted in 3983 patients (99.4%). Echocardiographic evaluation at one month follow-up revealed complete closure in 99.6% of those patients who had a device implanted. Thrombus formation in one adult patient was the only major device related to procedural complication. During the follow-up period, no patient developed cardiac erosions, allergic reactions to nickel, or other major complications. CONCLUSIONS: Implantation of CSO provided satisfactory procedural and follow-up results with high success and no device-related cardiac erosions and nickel allergy.

Teamwork is one of the most important trend in modern medicine. Airway team were created in many places to respond in a multidisciplinary and coordinated way to challenging clinical problems which were beyond the possibility of an individual management. In this chapter, we illustrate the historical steps leading to the development of an airway team in a pediatric referral hospital, describe the present teamwork activity defining the key points for the creation of a team and discussing different organization models; finally we delineate possible future directions for the airway teams in the globalized world.

Coronary ostial stenosis is a rare congenital cardiac anomaly, frequently associated with hypoplasia of the proximal coronary artery. This condition is potentially life-threatening, as it may present with myocardial ischemia and sudden death. We present a case of left coronary ostial stenosis in a 48-day-old infant symptomatic for sudden cardiac arrest, who successfully underwent surgical angioplasty. Any cardiac arrest in a neonate or young infant should raise suspicion of coronary ostial stenosis/atresia, considering the difficulty in diagnosing this congenital heart defect.

BACKGROUND: Double-outlet right atrium (DORA) is a rare congenital cardiac defect, where the right atrium (RA) is connected to both the right ventricle (RV) and the left ventricle (LV). Double-outlet right atrium is classified into two types, each containing two subtypes: malaligned atrial septum with common or single atrioventricular (AV) valve and malaligned ventricular septum (VS) with adequate or inadequate RV. The VS type is characterized by straddling right AV valve (RAVV) with intact VS, resulting in two RAVV orifices. METHODS: We report a case of "acquired DORA" in a 17-year-old male patient previously treated with subaortic VSD closure. At admission, we diagnosed DORA with VS malalignment and adequate RV. The patient had 2 orifices within the RAVV, connecting the RA to both the RV (via RAVV orifice 1) and the LV (via RAVV orifice 2). The latter was insufficient, with severe LV to RA shunt. A review of the literature indexed in PubMed and Scopus databases was undertaken. RESULTS: The patient underwent biventricular repair through closure of the RAVV orifice 2 with a pericardial patch. Pacemaker implantation for complete AV block was necessary. Postoperative course and follow-up were regular. The literature review showed 39 cases of DORA, of which 8 had a malaligned VS and an adequate RV, as in our case. CONCLUSION: Acquired DORA is an interesting post-surgical variant of a rare congenital heart defect. Biventricular repair is a feasible and viable option, which involves closing the third AV orifice. Careful attention is required in order to avoid injury to the conduction system.

A comprehensive description of morbidity and mortality as well as risk factors of interventional cardiac catheterization performed in neonatal age was reported in our paper recently published on the International Journal of Cardiology (IJCA28502; PII: S0167-5273(20)30384-3; DOI: 10.1016/j.ijcard.2020.04.013). Eight Italian high-volume centres of Paediatric Cardiology were involved in this observational, retrospective data collection and analysis. In this dataset, clinical and procedural characteristics of 1423 newborns submitted to 1551 interventional cardiac catheterization procedures were analyzed. Primary outcomes were considered procedure and in-hospital mortality as well as major adverse event and procedural failure rates. Secondary outcomes were considered minor adverse events and need for blood transfusion. Targets of this data analysis were: 1) to evaluate the overall major risk factors of interventional cardiac catheterization; 2) to identify the most hazardous interventional procedures; 3) to assess possible trends of individual procedures as well as their outcome over time; 4) to find possible relationships between the volume activity of any centre and the procedure and follow-up outcome. In particular, this Data in Brief companion paper aims to report the specific statistic highlights of the multivariable analysis (binary logistic regression) used to assess the impact of any potential risk factors on the type of procedure over a short-term follow-up.
