Interventional cardiology: characterization of the hemodynamic service in congenital cardiopathies of a Brazilian school hospital

Cardiac catheterization technology allows the diagnosis, follow-up and treatment of congenital or acquired diseases. 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.
