Spontaneous closure of isolated Ventricular septal defect in the first year

Background/Aim: Ventricular septal defect (VSD) is the most common congenital heart anomaly that in many cases closes spontaneously. The spontaneous closure (SC) rate of VSD varies widely between studies. aim this study was to identify clinical and echocardiographic factors influencing SC isolated first year life among a group patients presented at Paediatric Clinic. Methods: Prospective performed 60 consecutive with trivial, small or medium during life. Patients were divided into groups, according gender gestational age patient, type, number size persistence pulmonary hypertension. described comparison diameter aortic annulus (VSD/Ao ratio). Results: At time diagnosis, mean VSD/Ao ratio 0.33 mm. Muscular more (76.7 %) than perimembranous (23.3 %). occurred % all patients, case muscular 73.9 14.3 %. There negative correlation rate. probability for given by formula: = -1.82933X+1.20145. None hypertension closed. Conclusion: It found type significant predictors SC, while patient defects not. This can be useful predicting natural outcome make proper follow-up management plans.
