ABSTRACT
ABSTRACT Introduction: The coronavirus disease 2019 (COVID-19) pandemic has required changes in the management of pediatric cardiac surgery. We would like to share the patient treatment and surgical management strategies employed in our Pediatric Cardiovascular Surgery Clinic during the COVID-19 pandemic. Methods: A total of 112 patients were followed up in our clinic between 11.03.2020 and 02.07.2020. Their mean age was 1,118 (4-5,740) days. Management and treatment were performed by our pediatric heart team (pediatric cardiac anesthetists, general pediatricians, pediatric cardiologists, pediatric cardiac surgeons, and an infectious diseases specialist). We prepared new protocols and a surveillance system specific to the pandemic to prevent in-hospital transmission and reduce postoperative mortality and morbidity; our operations were performed according to these protocols. All decisions pertaining to the operation timing and treatment strategy of our COVID-19-positive patients were made by the same team. Results: During the study period, a total of 112 patients, 69 boys and 43 girls, were hospitalized in our clinic. A total of 333 COVID-19 real-time polymerase chain reaction tests were performed on patients and accompanying persons; positive results were found in three patients and two accompanying individuals. Conclusion: By employing new protocols and a surveillance system throughout the healthcare system, we think that early diagnosis and treatment of the pediatric congenital heart disease population, which is susceptible to infections, can continue unperturbed. This and similar approaches can increase postoperative success and prevent transmission in the pediatric population - which are frequently COVID-19 asymptomatic.
ABSTRACT
Objective: We have retrospectively analyzed the results of the operations made for aortic valve endocarditis in a single center in 26 years. Methods: From June 1985 to January 2011, 174 patients were operated for aortic valve endocarditis. One hundred and thirty-eight (79.3%) patients were male and the mean age was 39.3±14.4 (9-77) years. Twenty-seven (15.5%) patients had prosthetic valve endocarditis. The mean duration of follow-up was 7.3±4.2 years (0.1-18.2) adding up to a total of 1030.8 patient/years. Results: Two hundred and eighty-two procedures were performed. The most frequently performed procedure was aortic valve replacement with mechanical prosthesis (81.6%). In-hospital mortality occurred in 27 (15.5%) cases. Postoperatively, 25 (14.4%) patients had low cardiac output and 17 (9.8%) heart block. The actuarial survival rates for 10 and 15 years were 74.6±3.7% and 61.1±10.3%, respectively. In-hospital mortality was found to be associated with female gender, emergency operation, postoperative renal failure and low cardiac output. The long term mortality was significantly associated with mitral valve involvement. Male gender was found to be a significant risk factor for recurrence in the follow-up. Conclusion: Surgery for aortic valve endocarditis has significant mortality. Emergency operation, female gender, postoperative renal failure and low cardiac output are significant risk factors. Risk for recurrence and need for reoperation is low. .
Objetivo: Analisamos, retrospectivamente, os resultados das operações realizadas para endocardite valvar aórtica em um único centro em 26 anos. Métodos: De junho de 1985 a janeiro de 2011, 174 pacientes foram operados por endocardite da válvula aórtica. Cento e trinta e oito (79,3%) pacientes eram do sexo masculino e a média de idade foi de 39,3 ± 14,4 (9-77) anos. Vinte e sete (15,5%) pacientes apresentavam endocardite na prótese valvar. O tempo médio de acompanhamento foi de 7,3 ± 4,2 anos (0,1- 18,2) totalizando 1.030,8 paciente/ano . Resultados: Duzentos e oitenta e dois procedimentos foram realizados. O procedimento mais realizado foi a substituição da valva aórtica por prótese mecânica (81,6 %). A mortalidade intra-hospitalar ocorreu em 27 (15,5%) casos. No pósoperatório, 25 (14,4% ) pacientes apresentaram baixo débito cardíaco e 17 (9,8%) bloqueio cardíaco . As taxas de sobrevida atuarial para 10 e 15 anos foram 74,6±3,7% e 61,1±10,3%, respectivamente. A mortalidade intra-hospitalar foi encontrada esteve associada com o sexo feminino, operação de emergência, insuficiência renal pós-operatória e baixo débito cardíaco. A mortalidade a longo prazo foi significativamente associada com o envolvimento da válvula mitral. O sexo masculino encontrado mostrou-se um fator de risco para a recorrência no seguimento. Conclusão: A cirurgia para tratamento da endocardite da válvula aórtica apresenta mortalidade. Operação de emergência, o sexo feminino, insuficiência renal pós-operatória e baixo débito cardíaco são fatores de risco significativos. O risco de recorrência e necessidade de reoperação são baixos. .
