    Acute Respiratory Distress Syndrome and Myocarditis Caused by Human Metapneumovirus in a Child
    (2020) Yakut, Kahraman; Varan, Birgul; Erdogan, Ilkay; Tokel, Kursad; 0000-0002-6759-1795; 0000-0002-9221-5636; AAJ-2305-2021; AAF-3253-2021
    Human metapneumovirus (hMPV), a recently described paramyxovirus, has commonly been associated with upper and lower respiratory tract infections in young children. Severe infections including cardiovascular disease associated with hMPV have been particularly reported in older and immunocompromised patients; however, there has been no previous report of hMPV causing myocarditis in a child. In this article, we present a rare case with acute respiratory distress syndrome and myocarditis associated with hMPV in a child.

    Case report and the surgical treatment of two cases with pulmonary atresia in which pulmonary arteries is circulated by coronary arteries
    (2018) Tokel, Kursad; Yakut, Kahraman; Varan, Birgul; Erdogan, Ilkay; Ozkan, Murat; 0000-0002-6719-8563; 0000-0001-6887-3033; 0000-0002-6759-1795; 29664428; ABB-1767-2021; AAJ-2305-2021; ABB-2220-2021; AAF-3253-2021
    Pulmonary atresia (PA) and ventricular septal defect (VSD) can occur in a variety of ways, from simple valve atresia to a condition in which circulation to the pulmonary bed occurs through collateral arteries separated from the aorta and there are no real pulmonary arteries, or they are present but hypoplastic. The size of the pulmonary arteries and concomitant complex cardiac lesions are important in making decisions about treatment and correctional alternatives. While complete correction surgeries in the style of a correction of tetralogy of Fallot are performed in simpler cases, many very invasive procedures are also performed and the resulting quality of life is very variable. The size of the pulmonary artery and its branches and the presence of accompanying collateral vessels are determining factors in the management of the disease. In this report, 2 cases of VSD and PA, in which the circulation of the pulmonary arteries was through the coronary arteries, diagnosed as a result of echocardiography performed following murmurs heard during examination, are described. The first patient was 40 days old and the second was 2 days old. In the second case, diagnosis was confirmed by catheter angiography, and in the first case, the final diagnosis was made during surgery. The aim of this report is to emphasize the importance of pulmonary artery size, the presence of pulmonary confluence, the origin of circulation, and concomitant collateral arteries when considering treatment methods.

    Long-term outcomes in patients who underwent surgical correction for atrioventricular septal defect
    (2018) Ayabakan, Canan; Sarisoy, Ozlem; Tokel, Kursad; Ozkan, Murat; Turkoz, Riza; Aslamaci, Sait; 30297581
    Objective: The follow-up results of patients operated for atrioventricular septal defect (AVSD) during 1996-2016 at Baskent University are presented. Methods: Data obtained from hospital records consists of preoperative echocardiographic and angiographic details, age and weight at surgery, operative details, Down syndrome presence, postoperative care details, early postoperative and latest echocardiographic findings and hospitalization for reintervention. Results: A total of 496 patient-files were reviewed including 314 patients (63.4%) with complete and 181 (36.6%) with partial AVSD (48.4% of all patients had Down syndrome). Atrioventricular (AV) valve morphology was Rastelli type A in 92.2%, B in 6.5%, and C in 1.3% of patients. The operative technique used was single-patch in 21.6% (108), double-patch in 25.8% (128), and modified single-patch (Wilcox) in 52.5% (260) of patients. The follow-up time was 37.79 +/- 46.70 (range, 0-198) months. A total of 64 patients (12.9%) had a rrhythmias while in the intensive care unit; pacemaker was implanted in 12 patients. A total of 78 patients (15.7%) were treated for pulmonary hypertensive crisis. The early morbidity and mortality in the postoperative first month were calculated as 38% and 10%, and the late morbidity and mortality (>1 month) were calculated as 13.1% and 1.9%, respectively. The rate of reoperation in our cohort was 8.9%. Conclusion: Although the early morbidity and mortality are low in AVSD operations, the rate of reoperations for left AV valve insufficiency are still high. Although Down syndrome is not a risk factor for early mortality, the co-morbid factors, such as longer postoperative mechanical ventilator or inotropic support, lead to higher risk for morbidity. The frequency of pulmonary hypertension and consequent complications are also high.
