Background Transcatheter closure of perimembraneous ventricular septal defect still poses a challenge due to the adjacent structures of the tricuspid and aortic valves and the risk of atrioventricular block. We report our experience at 2 centers using the KONAR-MF (multifunctional occluder) ventricular septal defect device, which gained its CE mark in May 2018. Methods A retrospective study was carried out on all patients who underwent transcatheter ventricular septal defect closure with the KONAR-MF (multifunctional occluder) ventricular septal defect device at 2 centers. Results A total of 47 patients were identified. The median age and weight of the patients were 25.8 months and 11 kg. The ventricular septal defects that were closed in 5 cases were post-operative hemodynamically significant residual ventricular septal defects. Forty-eight devices were used in the 47 cases. As for the location of the ventricular septal defect, 40/48 (83.33%) ventricular septal defects were perimembranous and 8/48 (16.66%) were muscular. The percutaneous device closure was successful in 46 procedures (95.8%). Device embolization was observed in 2 patients, and a significant residual shunt was observed in 2 cases. In the follow-up, there was no enhancement in the residual shunt in the remaining cases. Temporary atrioventricular block occurred in 2 cases during the procedure and improved after long sheath withdrawal. Conclusion Soft, flexible, and low-profile KONAR-MF (multifunctional occluder) occluders ensure easy and safe implantation, and small sheath sizes allow for their use in small infants. Although near and mid-term follow-ups did not indicate any permanent atrioventricular block, a larger sample of patients and a longer follow-up period is necessary to understand long-term outcomes.

Pulmonary artery pseudoaneurysms are uncommon. They may occur secondary to trauma, infectious diseases, vasculitis syndromes, neoplasms, congenital diseases, and pulmonary hypertension. Due to increasing number of cardiac interventions, iatrogenic complications are among the major causes of pulmonary artery pseudoaneurysms. In this report, we present a 6-month-old patient with pulmonary pseudoaneurysm that occurred following pulmonary balloon angioplasty for the relief of a pulmonary band.

Abstract Introduction: In this report, we aim to present our algorithm and results of patients with congenital cardiac disorders who underwent surgical or interventional procedures during the peak phase of the pandemics in our country. Patients and methods: The first COVID-19 case was diagnosed in Turkey on 11 March, 2020, and the peak phase seemed to end by the end of April. All the patients whom were referred, treated, or previously operated but still at the hospital during the peak phase of COVID-19 pandemics in the country were included into this retrospective study. Patient’s diagnosis, interventions, adverse events, and early post-procedural courses were studied. Results: Thirty-one patients with various diagnoses of congenital cardiovascular disorders were retrospectively reviewed. Ages of the patients ranged between 2 days and 16 years. Seventeen cases were males and 14 cases were females. Elective cases were postponed. Priority was given to interventional procedures, and five cases were treated percutaneously. Palliative procedures were preferred in patients whom presumably would require long hospital stay. Corrective procedures were not hesitated in prioritised stable patients. Mortality occurred in one patient. Eight patients out of 151 ICU admissions were diagnosed with COVID-19, and they were transferred to COVID-19 ICU immediately. Three nurses whom also took care of the paediatric cases became infected with SARS-CoV-2; however, the children did not catch the disease. Conclusion: Mandatory and emergent congenital cardiac percutaneous and surgical procedures may be performed with similar postoperative risks as there are no pandemics with meticulous care and preventive measures.

Congenital rupture of tricuspid chordae tendinea leading to severe tricuspid insufficiency is an extremely rare pathology associated with signs and symptoms of congestive heart failure presenting at birth. If the diagnosis and treatment of this pathology are not made early in life fetal demise may become inevitable. We herein present a neonate with central cyanosis and congestive heart failure due to rupture of an anterior leaflet chordae resulting in severe insufficiency of the tricuspid valve who was treated with appropriate surgery.
