REAL APARICIO, Chantal Marie; SPINZI, Lorena  y  ROMERO, Fátima. Characteristics of post-operated patients of interventricular communication in the Department of Pediatric Cardiology of the Hospital de Clinics. Rev. Nac. (Itauguá) [online]. 2018, vol.10, n.1, pp.36-56. ISSN 2072-8174.


ventricular septal defect (VSD) is a frequent congenital heart disease, which varies from a minute defect without hemodynamic consequences to a large defect, accompanied by heart failure and pulmonary hypertension. Although medical treatment manages to control heart failure, it is undoubted that in some cases surgical closure is necessary.


to describe the clinical characteristics of the pre- and post-operative of patients undergoing IVC closure.


observational, descriptive, retrospective study, which included 74 patients from 3 months to 16 years of age, undergoing surgical closure of VSD in the Pediatric Cardiology Department of Hospital de Clínicas FCM-UNA in the 2012-2017 period. Clinical, electrocardiographic and echocardiographic variables are described in the pre- and postoperative period. Cases of intra-operative death, cases with complex congenital heart defects associated with VSD and atrioventricular canal were excluded.


the most frequently intervened VSD was the perimembranous type (95%) and the majority with preoperative grade I functional class (52%). Post-operative parameters (electrocardiogram and echocardiography) normalized in most patients, with a decrease in evidence of cardiac chamber overload. Infectious (67%) and pulmonary (pneumothorax and atelectasis) complications occurred. The mortality was 1.3%.


Surgical closure of the VSD had significant morbidity, low mortality and excellent functional recovery.
