Background: Transcatheter closure of atrial septal defect (ASD) has become the treatment of choice for most patients. About 5% of them suffer from transient headache episodes (THE) after the procedure, whose etiology is unclear., Aims: To evaluate risk factors for THE occurrence after transcatheter closure of ASD in the pediatric population., Methods: Eight hundred and forty patients, after transcatheter ASD closure with nitinol devices, from a single center, were included in retrospective analysis. THE was defined as occurring up to 24 hours after the procedure. A logistic regression model including age, weight, ASD diameter, device size, presence of nitinol coating on the device, fluoroscopy time, application of balloon calibration, device oversizing, and residual shunt after 24 hours was created to evaluate risk factors for THE occurrence., Results: There were 40 patients with THE (4.8%), 70% female and 30% male. The median age was 13 (7.35-16) years. In patients with headache, balloon calibration (BC) was performed more frequently (82.5% vs. 43.3%; P <0.001). The balloon waist median (interquartile range [IQR]), 19 (16-22) mm vs. 15 mm (12-18) mm (P <0.001), and device size median (IQR), 18 (13.5-22) mm vs. 14 (11-17) mm (P <0.001) were larger, and residual shunt after 24 hours (12.5% vs. 4.9%; P = 0.03) and a year (7.5 vs. 1.0%; P <0.001) were more frequent. ASD size and the prevalence of double/multiple ASD were similar in both groups. Age, BC application, no nickel release protection, duration of fluoroscopy, and device oversizing were predictors of THE (P <0.001)., Conclusions: BC during percutaneous ASD closure and the lack of a protective layer against nickel release on the device are risk factors for headache occurrence in the early postprocedural period.

Background: Transcatheter patent ductus arteriosus (PDA) closure has become the first‑choice method of treatment in the majority of patients. However, device selection poses a challenge., Aims: This study aimed to analyze periprocedural and 1‑year outcomes of PDA transcatheter closure performed with different devices throughout a 25‑year time period in a single center., Methods: All 1036 patients who underwent transcatheter PDA closure between 1993 and 2020 were included in retrospective analysis. Various devices were used: the Rashkind device (RD; n = 25), coils (n = 469), nitinol duct occluders type I (DO I; n = 300), type II (n = 32), type II additional sizes (ADO II AS; n = 209), as well as off‑label devices: vascular plugs and atrial septal and muscular ventricular septal defect occluders (n = 17). Data on 24‑hour and 1‑year follow‑up were available for 100% and 78.9% of the study patients, respectively., Results: The procedure was successful in 98.6% of the study patients, with a major complication rate of 0.2%. Complete PDA closure after a year was observed in 81.8% of the patients treated with RD, 93.7% of those with coils, and 100% of those with duct occluders. There were no differences between Amplatzer DO I (n = 159) and its DO I copies manufactured in China (n = 141) with regard to success, efficacy, and complication rates. Recently, ADO II AS has replaced coils and become the preferred device to close small‑to‑moderate PDA., Conclusions: Transcatheter PDA closure with all types of nitinol duct occluders is safe and effective, with no residual shunting at 1‑year follow‑up. Due to higher efficacy, ADO II AS has replaced coils in the treatment of smaller PDA.

Background: Atrial septal defect (ASD) type 2, according to current standards, is closed percutaneously usually after the child has reached the age of four to five years. There are limited data regarding such treatment in younger infants., Aim: We sought to evaluate the feasibility, safety, and efficacy of percutaneous ASD closure in children under three years of age., Methods: The research group consisted of 157 children less than three years old with haemodynamically significant ASD, who underwent effective transcatheter ASD closure in a single tertiary centre between 1999 and 2014. The mean procedural age of the treated children was 2.2 years and mean weight was 12.5 kg. In all cases nitinol wire mesh devices were applied (mostly Amplatzer Septal Occluders). ASD was closed using standard technique (except a few cases wherein the left disc of the implant was inserted initially into the right pulmonary vein to prevent oblique position of the device). Procedure-related complications were divided into major and minor ones., Results: Atrial septal defect was closed in 149 children: 97 with a single ASD and 52 with double/multiple ASD. The procedure was abandoned in eight patients (three with single and five with double/multiple ASD). No death or implant embolisation occurred during the procedure or follow-up, and there was one case of major postprocedural complications. Normalisation of the right ventricular diameter occurred in all patients during one-year follow-up. In the majority of children acceleration of physical development and resolution of accompanying morbidity were observed in follow-up., Conclusions: Percutaneous ASD closure can be performed safely in children under three years of age with low risk of peri- or postprocedural complications.

Background and Aim: Patent foramen ovale (PFO) may result in a cerebrovascular event - a presumed paradoxical embolism (PE). However, the presence of this phenomenon among paediatric patients was rarely evaluated. Transcatheter PFO closure was considered to be a method of treatment in such patients., Methods: For evaluation clinical data and long-term outcome, we reviewed records of patients below 18 years of age, with history of cerebrovascular event related to PE, who underwent procedure of percutaneous PFO closure in years 1999-2014 in our department., Results: Among 230 patients with cerebrovascular events who had PFO closed percutaneously, seven children (aged 12-16 years, five male) were selected. Indications for closure were cryptogenic stroke in two patients and transient ischaemic attack (TIA) in five patients. Diagnosis of PFO was established by transthoracic echocardiography, with right-to-left shunt (RLS) through PFO confirmed by transoesophageal echocardiography. Contrast transcranial Doppler (c-TCD) was performed preprocedurally in four patients, revealing significant RLS. For percutaneous closure of PFO different occluders (Starflex, Amplatzer PFO devices, Cardio-O-Fix) were used. Closure was successfully completed in all patients and no procedure-related complications were observed. Postprocedural c-TCD six months after closure revealed no significant RLS. During follow-up (3 to 10 years) one patient had an episode of recurrent TIA; however, in this patient paroxysmal atrial fibrillation was found during the follow-up period., Conclusions: Cerebral embolism due to PFO is uncommon in children. Transcatheter PFO closure in this group of patients is a safe and effective procedure. C-TCD is plausible technique for detection RLS and monitoring PFO closure efficacy in this group of patients.

Objectives: The aim of the study is to describe both professional and social activities of patients after heart transplant., Material and Methods: Ninety-five heart transplant patients treated at the Silesian Center for Heart Diseases in Zabrze were surveyed, comprising 29 women (30.5%) and 66 men (69.5%). The average age of respondents was 54.3 years old (standard deviation (SD) = 15 years); the average period that had elapsed since the heart transplant was 7.1 years (SD = 4 years). We designed a questionnaire as a tool for collecting information from patients., Results: Twenty-five percent of patients worked at the time of completion of the questionnaire. Eighty percent of those patients were working before and after the transplant, 20%--only after transplantation (p < 0.05). A different job position at a new workplace had 47.8% of patients, 34.8% of them had the same job position at the same work place as they had had before, 63.4% of the heart transplant respondents were pensioners. Eighty-two percent of patients had a certificate with a designated degree of disability--among them: 69% had a certificate for a significant degree of disability, 22%--for a moderate degree of disability. Among those surveyed, 52.5% said that their financial situation had not changed whereas 34.5% of those surveyed reported a change for the worse. Thirty-seven percent of respondents reported changes in family relationships. Seventy-seven percent reported that they received help from family members, as compared with 19% who did not., Conclusions: Only 25.3% of the patients treated at the Silesian Centre for Heart Diseases after heart transplant are employed and it is one of the lowest employment rates in this category of patients in Europe. One third of working patients have the same work place as they had before their operation. Heart transplant is a cause of changes in family relationships. Most often family bonds are strengthened but sometimes family members become nervous, impatient and unwilling to talk about the transplant., (This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.)
