Holter and ECG Changes After Transcatheter Closure Of VSD In Children

Ventricular septal defect (VSD) is the most common congenital heart now affecting children, which makes up 20 % of isolated congenital heart condition. Although VSD can develop in any area of the inter ventricular septum, the perimembranous VSD and muscular VSD which can occur anteriorly, posteriorly, inlet, or outlet, are the most frequent morphological forms. The supracristal varity is less prevelant. While many VSDs close spontaneously, if they do not, large defects can lead to detrimental complications such as pulmonary arterial hypertension (PAH), ventricular dysfunction, and an increased risk of arrhythmias. Hemodynamic impairment may arise according to the size and flow of the VSD. Hemodynamically unstable patients particularly benefit from a successful closure. After conventional open surgery to treat VSDs, complications from cardiopulmonary bypass, are infection, postpericardiotomy syndrome, chylothorax, and a full atrioventricular block are still conceivable (e.g., myocardial, and pulmonary injury, electrolyte imbalance, coagulopathy, and acute renal failure). Furthermore, when compared to nonsurgical treatments, prolonged postoperative stays in the ICU or hospital are required . The requirements for transcatheter intervention are determined by the size and type of VSD. Transcatheter closure of a moderate-sized VSD with congestive heart failure, failure to thrive, substantially enlarged left atrium and LV, or increased pulmonary artery pressures is frequently recommended (or both). A pulmonary-to-systemic flow ratio larger than 2:1 is also required. Large VSDs with RV and pulmonary artery systolic pressures close to the left ventricular and aortic systolic pressures should be closed. Since the first case was reported in 1988 and had satisfactory results, catheter- based therapies have demonstrated promising results in comparison to surgery Arrhythmia, especially CAVB, is one of the most important complications after transcatheter occluder closure of pmV
