ASSESSMENT OF THE LEFT VENTRICULAR DIASTOLIC FUNCTION AFTER PERCUTANEOUS ATRIAL SEPTAL DEFECT CLOSURE IN CHRONIC PHASE

Recent guidelines recommend intervention for atrial septal defect (ASD) when ASD patients have evidence of right ventricular dilatation. It is unclear the effect on cardiac function after ASD closure, especially left ventricular (LV) diastolic function after shunt blood flow disappeared and volume
