Successful cardiac catheterization and pacemaker implantation can be performed safely in selected pregnant patients using an electroanatomic mapping system guidance without fluoroscopy.

Objective We report the early and long‐term results of the strategies and surgical methods used in our center to treat pediatric patients who underwent surgical intervention to correct Ebstein anomaly (EA) in our center. Materials and Methods In our study, a consecutive sample of 29 patients who underwent surgery for EA between February 2011 and February 2020 in our center were evaluated retrospectively. Results The 29 patients underwent a total of 40 operations. Univentricular repair was performed in 5 (17.2%), 1.5 ventricular repair in 5 (17.2%), and biventricular repair in the remaining 19 (65.5%) patients. Cone reconstruction (CR) was performed in eight (27.5%), non‐Cone tricuspid valve (TV) repair technique in five (17.2%), ring annuloplasty in two (6.9%), and TV replacement in two patients (6.9%) who had undergone biventricular repair. In two patients (6.9%), only close an atrial septal defect. Two (6.9%) patients underwent a second operation for advanced tricuspid regurgitation (TR) in the early period. None of the 15 patients who underwent CR and TV plasty had moderate or advanced TR before discharge. Early mortality was seen in 1 (3.4%) patient. The mean follow‐up period of the patients was 48.4±27.6 months. Three (10.7%) of the patients who were discharged after their first operation later underwent a second operation for TV regurgitation in the long term. No mortality was observed in any patient during long‐term follow‐up. Conclusion Surgical treatment of EA is difficult, but its overall results are good. The anatomical repair rate is lower in neonatal and infant patients requiring surgery, but most of these patients underwent biventricular repair. Our long‐term results demonstrated an acceptable survival rate, low mortality in the early postoperative period, and low incidence of re‐intervention and morbidity.

Due to its safety profile, cryoablation (Cryo) for atrioventricular nodal reentrant tachycardia (AVNRT) is more commonly preferred over radiofrequency (RF) ablation in children in recent years. Recent studies demonstrated high long-term success rates comparable to radiofrequency ablation. The aim of this prospective study was to compare the efficacy and safety of an 8-mm-tip versus 6-mm-tip Cryo catheter in the treatment of AVNRT in children. A total of 125 consecutive patients over 10 years of age with AVNRT were included. EnSite system (St. JudeMedical, St Paul, MN, USA) was used to reduce or eliminate fluoroscopy. The acute procedural success was 100% in both groups. The prodecure duration for the 8-mm-tip group was shorter (151.6 ± 63.2 vs. 126.6 ± 36.7 min, p < 0.01, respectively). Fluoroscopy was used in only 7 patients. The mean follow-up duration was 14.6 ± 8.4 months (median 13.5 months, min. 3 months and max. 27 months). The recurrence rate for AVNRT was also comparable between the two groups (6-mm tip: 9.6 vs. 8-mm tip: 8%). Cryo of AVNRT is a safe and effective procedure with comparable acute and mid-term follow-up success rates using 6-mm and 8-mm-tip catheters in children. In addition, procedure duration is shorter with an 8-mm-tip Cryo catheter.

Sipahi S, Nacaroğlu HT, Can D, Günay İ, Ünsal-Karkıner CŞ, Kamalı H, Özdemir A, Günay T. Effect of socioeconomic status on allergic diseases and atopy in school children. Turk J Pediatr 2017; 59: 670-677. Higher family socioeconomic status (SES) has been suggested as a risk factor for allergic diseases. We investigated the effect of SES on the prevalence of allergic diseases and atopy. The study included 13-14-year-old primary school students in Kemalpaşa, Turkey. The International Study of Asthma and Allergies in Childhood phase 1 questionnaire was administered to all students to identify allergic diseases. Those identified as having allergic diseases underwent a skin prick test (SPT). Group I included students with allergic diseases and a positive SPT. Group II comprised students with allergic disease who were SPT negative. The control group was randomly selected from the students with no allergic diseases. Three weighted SES scores were calculated for each student (equally weighted, education-weighted, and social class-weighted). SES was classified as lower, middle, or upper according to the weighted SES scores. Allergic diseases were detected in 657 of the 1,373 children who participated in the study. A higher percentage of children with allergic diseases and atopy were in the lower SES group in all weighted SES analyses compared with controls (Group I: 59%, 83.1%, 67.5%; Group II: 62.9%, 80%, 63.5%; control group: 12.4%, 12.9%, 21.2%). Significantly more children with allergic and atopic diseases (Groups I and II) were in the lower SES group compared with the control group (p < 0.001). In contrast to the hygiene hypothesis, we found the incidence of atopic disease was higher in families with lower SES.

BackgroundHemodynamically significant muscular ventricular septal defects in children after the infantile period are a rare occurrence and ideal for transcatheter closure. In cases of severe concomitant pulmonary hypertension, it may be necessary to fenestrate the device. In this report, we present an 18-year old patient with a large mid-trabecular ventricular septal defect and severe pulmonary hypertension that underwent percutaneous closure of the defect with a home-made fenestrated atrial septal occluder.Case presentationAn 18-year-old female patient referred to us with complaints of dyspnea (NYHA score of 2–3). Physical examination revealed an apical rumble and a harsh second heart sound. Echocardiographic examination revealed a large mid-trabecular ventricular septal defect with bidirectional shunt and the widest diameter measuring 22 mm on 2D echocardiography. Left and right heart cavities were enlarged. Before and after the vasoreactivity test performed during cardiac catheterization, average aortic pressure was 65 → 86 mmHg, average pulmonary artery pressure: 58 → 73 mmHg, Qp/Qs: 1.6 → 3.2, PVR: 4.6 → 4.3 Wood/U/m2 and PVR/SVR: 0.5 → 0.2. On left-ventricular angiocardiogram, the largest end-diastolic defect diameter was 21 mm. The closure procedure was performed with transthoracic echocardiographic guidance, using a 24 mm Cera septal occluder and a 14 F sheath dilator to make a 4.5-5 mm opening. Measured immediately after the procedure and during cardiac catheterization one month later, average aortic pressure was 75 → 75 mmHg, average pulmonary artery pressure: 66 → 30 mmHg, Qp/Qs 1.5 → 1.4, PVR: 4.4 → 2.9 Wood/U/m2 and PVR/SVR: 0.4 → 0.2. Transthoracic echocardiographic examination performed 24 hours after the procedure showed a max 35–40 mmHg gradient between the left and right ventricles through the fenestration. After the procedure, we observed sporadic early ventricular systoles and a nodal rhythm disorder that started after approximately 12 hours and spontaneously reverted to normal 9 days later.ConclusionIn patients with large ventricular septal defects, large atrial septal occluders may be used. In cases with risk of pulmonary vascular disease, a safer option would be to close the defect using a manually fenestrated device.
