An example of this is the improvement of methods performed especially for the pediatric aged group. Aim: To characterize the Congenital Cardiopathies´Hemodynamic Service of a Brazilian School Hospital regarding the variables - gender, age group, types of health care system (public or private), cardiac anomaly diagnosis and surgical intervention or percutaneous catheterization treatment. Material and Methods: Retrospective, descriptive study by analysis of the Brazilian Hemodynamics Service database, from 1999 to 2017, and variables for characterization were recorded. Results: A total of 667 catheterization reports were analyzed in 573 patients, which 328 (57%) are males and 245 (43%) are females. By the public health care system, 605 (91%) exams were performed and, by the private health care system, 62 (9%) exams were performed. Analyzes between number of patients (p=0.2639) and number of exams performed (p=1.0000) and types of health care system were not statistically significant. The percutaneous interventional procedure was therapeutic in 6.5% (42/667) among all those carried out. Pulmonary valve stenosis (15.5%) and Tetralogy of Fallot (14.0%) were among the most prevalent diagnoses in male gender, while complex congenital heart disease (19%) and ventricular septal defect (14%), in the female gender. Conclusion: The profile of this Brazilian Hemodynamic Service indicates predominance of procedures in both nurseling and childhood males and performed by the public health care system; the most frequent heart diseases were complex congenital heart disease, pulmonary valve stenosis, Tetralogy of Fallot and interventricular communication.

INTRODUCTION Cardiology in congenital heart disease has shown incalculable progress and, at the present time, there has been a real transformation both in the diagnostic spectrum and in the conduct in general. The evolution of the different exams performed in clinical and semiological exams, in the systematization of clinical knowledge, up to the endless help of echocardiography, reaching, interventional catheterization, the hemodynamic milestone in diagnostic/therapeutic procedure, in addition to assisting open surgical intervention, when necessary, for the elaboration of the most adequate surgical plan in relation to the diagnosis of the anomaly (Mourato et al., 2014). Specifically, in the field of interventional catheterization, this progress occurred with Rashkind's atrioseptostomy in 1966, in the transposition of the great arteries (Rashkind & Cuaso, 1979). Currently, the technique extends to other anomalies such as pulmonary atresia with intact ventricular septum, tricuspid atresia, left atrioventricular valve atresia, mitral stenosis, among others. Furthermore, the method, in addition to widening the panorama of anomalies, has increased effectiveness, both in ISSN: 2230-9926 International Journal of Development Research Vol. 10, Issue, 02, pp. 33791-33797, February, 2020 Article History: Received xxxxxx, 2019 Received in revised form xxxxxxxx, 2019 Accepted xxxxxxxxx, 2019 Published online xxxxx, 2019 Available online at http://www.journalijdr.com Citation: Luiz Henrique Teixeira de Sabóia and Vânia Belintani Piatto. 2020. “Interventional cardiology: characterization of the hemodynamic service in congenital cardiopathies of a Brazilian school hospital”, International Journal of Development Research, 10, (02), 33791-33797.
