Sahyadri Hospital in Pune, India offers cardiology and ophthalmology services using advanced technologies like ECG, echocardiograms, and stress tests to diagnose and treat cardiovascular conditions. The hospital has experienced cardiologists who perform complex surgeries like angioplasty and pacemaker implantation to open blocked arteries and restore blood flow to the heart. Angioplasty is done through a small puncture by threading a catheter to the heart and inflating a balloon to open the blockage.
