When a healthcare provider listens to the heart with a stethoscope and hears a whooshing sound, atrial septal defects are diagnosed at Zulekha Hospital before or shortly after a child is born (heart murmur). An atrial septal defect is diagnosed using an echocardiogram, a chest X-ray, an electrocardiogram (ECG or EKG), a cardiac magnetic resonance imaging (MRI) scan, and a computed tomography (CT) scan. Zulekha Hospital's Cardiology Department is equipped with best-in-class technology and can perform both invasive and non-invasive tests.

The department performs Coronary and Peripheral Angioplasty with stenting, as well as Balloon Valvuloplasty for all Valvular Lesions, in addition to routine diagnostic invasive procedures such as Angiography and Catheterization studies. PDA device and coil closure, as well as ASD device closure, have been performed on patients of all ages. The hospital offers minimally invasive heart surgery, which involves making small incisions between your ribs on the right side of your chest to reach the heart rather than cutting through your breastbone as in open-heart surgery. Dr. Jayachandran Thejus and Dr. Krupal Reddy are some of the cardiac surgeons at Zulekha Hospital.
