    A rare cause of cyanosis in childhood: Pulmonary arteriovenous malformation
    (TURKISH SOC CARDIOLOGY, 2017-01-01) Guvenc, Osman; Saygi, Murat; Demir, Ibrahim Halil; Odemis, Ender
    Pulmonary arteriovenous malformation, which is defined as the presence of an abnormal connection between the pulmonary artery and pulmonary vein, is rarely seen. Although it generally presents as a congenital condition, it may be accompanied by hereditary hemorrhagic telangiectasia. Clinical signs vary according to the amount of shunt in proportion to the number and size of the fistulae. Patients may present with cyanosis and respiratory trouble. If the disease remains untreated, it may result in cardiac failure and infective endocarditis, thereby leading to the rupture of the aneurysmal fistula. Transcatheter embolization of abnormal vascular connection is the current treatment method in this disease. This article describes the case of an 8-year-old child. He was presented with the symptom of getting tired quickly. Transcutaneous oxygen saturation of 75\%, and pulmonary arteriovenous malformation were detected in his examination. Successful transcatheter embolization of the fistula was performed.

    Rare combination and transcatheter treatment during single session in an infant: Patent ductus arteriosus and major aortopulmonary collateral artery concordance
    (TURKISH SOC CARDIOLOGY, 2016-01-01) Guvenc, Osman; Odemis, Ender; Saygi, Murat; Demir, Ibrahim Halil
    Major aortopulmonary collateral arteries are abnormal vascular structures that may be seen in cyanotic diseases that progress with reduced pulmonary flow. They occur rather rarely in the absence of cyanotic congenital heart disease. Presently described is the case of an infant who underwent patent ductus arteriosus (PDA) and major aortopulmonary collateral artery occlusion in a single session, without presence of cyanotic congenital heart disease. To the best of our knowledge, this is the first case of congenital aortopulmonary collateral artery to be reported in a symptomatic infant with PDA.

    Toward Routine Minimally Invasive Ventricular Septal Defect Closure Via Right Lateral Minithoracotomy
    (FRONTIERS MEDIA SA, 2021-01-01) Aydin, Selim; Temur, Bahar; Basgoze, Serdar; Guzelmeric, Fusun; Guvenc, Osman; Erek, Ersin
    Background: Improving the surgical results and recent advancement of transcatheter techniques for closure of ventricular septal defect (VSD) increased the demand for minimally invasive approaches. In this study, we analyzed the results of the patients who underwent VSD closure with right lateral minithoracotomy (RLMT). Methods: Between September 2014 and February 2021, 24 patients underwent minimally invasive VSD closure with RLMT. The median age of the patients was 16 months (range, 4-84 months). Fifteen patients (62.5\%) were female. The median weight of the patients was 9.75 kg (range, 4.6-30 kg). The types of VSD were perimembranous in 19 patients, subaortic in three patients, inlet in one patient, and subpulmonic in one patient. Five patients had low-lying pulmonary stenosis in addition to VSD. Results: No perioperative death or major complication occurred during follow-up. All defects were repaired through RLMT. The median cardiopulmonary bypass time was 81 min (range, 44-163 min), and the aortic cross-clamp time was 65 min (range, 33-131 min). The median hospital stay was 6 days (range, 5-21 days). One patient had minimal (2 mm) residual left-to-right shunt. All families were satisfied with the cosmetic results during the follow-up. Conclusions: The RLMT method is a safe and effective alternative to standard median sternotomy for VSD closure and can be performed with favorable cosmetic and clinical results.
