Minimally Invasive Cardiac Surgery

It is more than a decade that Minimally Invasive Cardiac Surgery (MICS) has been developed. As the name suggest, it requires minimal (small) incision (opening) on the body to perform the complete surgery.

This method has revolutionised performance of cardiac surgeries. The doctor accesses the heart through few small incisions without cutting any bone, by only splitting the muscle.


He has operated patients from 3 yrs to 90 yrs and from different parts of the world like India, Saudi Arabia, Qatar, Yemen, U.A.E, Tanzania, Mozambique, Madagascar, U.K & Canada.

  • Minimally Invasive Cardiac Surgery or MICS CABG is the most well-known part of Dr. Hamdulay. He specializes in it and is doing everything to make it a mainstream surgery. This form of surgery lets a patient recover quickly and they can enjoy life thoroughly. It is also the chosen procedure for Diabetics and people with respiratory problems.
  • Total Artery Bypass Surgery is a common surgery performed in India due to the blocked arteries. The surgeon replaces the blocked or damaged arteries with healthy ones to avoid any further problems.
  • Valve Replacement is a surgery that is done when someone’s Valves do not work properly. The doctor performs the surgery as it is needed and they can even go home in 4 to 5 days.

What Patients have to say

Tikendarjit Gove

I came from Assam to Mumbai for my cancer surgery, during my treatment I came to know that I had multiple blockages which needed treatment before the cancer surgery. I met Dr. Hamdulay who did minimally invasive bypass surgery because of which i was ready for my cancer operation within 15 days.

Sarwar Shaikh – Patient From Dubai

I was working in Dubai, there I discovered that I had heart disease & I needed urgent surgery. I wanted to do my surgery in Mumbai so I started my research and I found Dr. Hamdulay through Internet. I had 5 blockages, he had performed minimally invasive bypass surgery because of which the recovery was very fast & I was fit to work again.

Mr. Shabbir Kumar – Bollywood Singer

I was suffering from multiple blockages in heart and felt heaviness and pressure in my chest. A stress test indicated that I needed a bypass surgery. I am glad Dr. Hamdulay was my surgeon, his caring approach helped me recover quickly.

Mr. Jayesh Katharia

The first impression was like that he didn’t see me as a patient, rather he saw me as a human being. The human touch inclined me, I decided to get operated by him. I started walking in 3 days after my minimal invasive bypass surgery.
