Patient Review of Dr. Marc Gerdisch

"Dr. Marc Gerdisch’s bedside manner was impeccable. All of my questions were answered before and after my mitral valve repair."

-- Angie Gregory, heart valve surgery patient

"It’s without question that Dr. Gerdisch is one of the best heart surgeons in the world. Not only is he an amazing surgeon but he has an amazing team. You can trust they will do their very best for you, and thankfully their “best” is world-class. They are masters of their craft, but what makes this team so special is their ACCESSIBILITY.

When you meet Dr. Gerdisch, you can tell he’s just a genuinely good man… with great women like Nicole and NP Cindy serving alongside him. He might not remember, but soon after I sent in my TEE disk, Dr. Gerdisch called me himself while sitting in his office reviewing it. After discharge, both NP Cindy and Dr. Gerdisch gave me their cellphone numbers before I left Indianapolis.

I messaged Cindy several times my first month post-op, and she always got back to me within a couple hours. Dr. Gerdisch told me to send him my 1 year post-op ECHO and he would review it. Bottom line, if you’re their patient, this team has your back. I don’t think there could be a more comforting feeling when navigating such a serious life event. I will forever be grateful for this team, and I know and believe God put my care in their hands for a reason.

Technical Notes (I know I would want them from a review):
- I had a very loud murmur related to mitral valve prolapse with severe regurgitation
- My 1 month post-op ECHO showed NO regurgitation
- I’m over two months post-op with NO audible murmur upon auscultation/by stethoscope (yep, I’m a nurse 😁)
- I had a mini-thoracotomy. I have a 2.5 inch scar on my right chest (yep, right side) that healed great and I’m sure will fade nicely with some silicone.
- I had no real pain post-op. I received a nerve block in the operation room. Two months out and I still feel a little numb under my right armpit and around my right nipple.
- I’m mid-30s. Going into surgery my BMI was approx. 25, I was exercising moderately 2-3 days per week, and would regard myself as in good health.

Get Prepared:
- Start eating heart healthy several months before surgery
- Stop alcohol (and smoking of course)
- Talk to your friends and family and talk to God about this major decision.

I pray that whoever reads this will experience God’s peace, guidance and comfort during this challenging time in your life. It’s OKAY to be anxious and scared. I certainly was. Take it to Christ."
