Write a ReviewMy 5-year-old daughter was diagnosed with a heart condition that required surgical intervention. It was an emotional time for us as parents. Dr Gagan Khullar explained the issue in simple terms and gave us time to process everything. The surgery was planned carefully, and we were updated regularly during the procedure. Post-surgery recovery took time, but she gradually improved. Seeing her become active again after weeks of worry was a huge relief. The entire process was handled with patience and clarity.
I have been managing a cardiac condition for a few years and consulted Dr Gagan Khullar for better guidance. He reviewed my history and suggested a structured plan instead of frequent medication changes. He focused on stabilising the condition and regular monitoring. Over time, my symptoms became more manageable. The clarity in treatment approach helped me feel more in control of my health.
I was very nervous before my scheduled heart surgery and had many doubts. Dr Gagan Khullar took time to explain the procedure and recovery expectations in detail. That conversation helped reduce my fear to some extent. The surgery went as planned, and post-operative care was well managed. Recovery took time, but regular follow-ups helped track progress. I slowly regained confidence in my daily activities.
My uncle had a sudden cardiac emergency, and everything happened very fast. We were referred to Dr Gagan Khullar during that time. He quickly assessed the situation and explained that immediate intervention was required. There was a lot of panic in the family, but his calm approach helped us stay focused. The procedure was done successfully, and the initial ICU phase was critical. Over time, he started recovering, and follow-ups ensured steady improvement. It was a difficult situation, but it was managed efficiently.
Another hospital suggested urgent heart surgery for my mother, and we were very confused. Before taking a final call, we consulted Dr Gagan Khullar. He went through all reports in detail and explained that the surgery could be planned in a more controlled manner. That explanation reduced a lot of pressure on us. He guided us step by step on how to proceed. Eventually, surgery was done successfully, and recovery was smoother than expected. We felt more confident after understanding everything clearly.
