Through examining the benefits of using percutaneous treatment as an alternative to surgically means to correct MS and ASD, it was found that combined percutaneous treatment (including balloon valvuloplasty for MS and Amplatzer septal occluder for closure of the ASD) has improved the patient's planimetric mitral valve area to 2.1 cm (as compared to the previous 1.5 cm), maximum diastolic gradient to 9 mmHg (compared to previous 17 mmHg), and mean diastolic gradient to 4 mmHg (as compared to previous 9 mmHg).
