What Patients Say About Us

I can now breathe and walk, both of which were extremely difficult prior to my relationship with Heart & Vascular Institute of Florida. Their staff and nurses are beyond superb. Thank you Doctors Ismail and Siddiqui!

Mr. Greene

I am so grateful to Dr. Siddiqui and his team for a 2nd chance at life! Because of his quick intervention, I am able to enjoy today and look forward to tomorrow.

Clarence Grandy

We have both had various procedures done with Dr. Siddiqui, and have found him to be pleasant, knowledgeable and willing to explain what he is doing. He is very patient and willing to take the time you need.

Richard and Mark Wilson

Professional staff at the new state of the art institute in Davenport has exceptional service, the latest equipment, and on site procedures. Dr. Siddiqui is friendly, professional, and a caring person…He has my highest trust and confidence.

Thomas Megna

The staff at Heart & Vascular Institute is always attentive and professional, and the wait time is usually short. Dr. Siddiqui always explains what he is going to do, what the procedure will accomplish and this brings about confidence in him and his practice. I highly recommend him and this practice to anyone who needs a heart or vascular Doctor.

Frank and Sandra Merrell

I have been coming to this institute for over a year. As a senior, the health of my heart is very important to me! Everyone here has been the very best to me and I am always treated with the most kindness. Dr. Siddiqui has always answered all my questions. My health is in good hands! I’m glad to be so well taken care of!

Michael F. Murphy

Dr Siddiqui, I appreciate you so much for your helping me and my cardiac problems. No other physician has been able to help me the way you have, THANK YOU!


I had a procedure at the cath lab in Haines City and I have never experienced a procedure the way that I did there. I was handled with the upmost perfect care. The staff were all educated to the highest and extremely knowledgeable. Because of the care I received there, I will recommend them to anyone!


Wonderful, wonderful, wonderful!!! That is all I can say about Heart and Vascular Institute.


I had a stress test at Heart and Vascular Institute and was amazed at the latest technology that was at the facility. Everything was top notch and state of the art!


I started seeing Dr Irfan Siddiqui in October of 2014 because my legs were always hurting. Because of the pain in my legs he decided to do an angiogram and found blockages that caused the pain. I am so thankful for him and his expertise, I truly feel like a new human being.


I want to thank you very much for saving my life with a stent. I really don’t know what I will do with the additional years but I will make the best of it and be eternally grateful for you.


Dr Siddiqui…by fixing my dads heart you stopped mine from breaking!


A huge thanks to you for your tremendous skills with my husbands cath and your patience with my anxiousness. Again, thank you from the bottom of our hearts!

Dr Siddiqui and office staff, I want to thank you for everything you have done!


Most of my family and I have a history of heart disease, but I’m so happy that I was told about Dr Siddiqui. He has been a wonderful help!”


Thank you so much Dr Siddiqui and staff for getting me in for a visit the very next day. You staff is a blessing to deal with.


Truly blessed to have found a great cardiologist in my area about 5 minutes from my house!


Finally after seeing two different cardiologists, I finally found the BEST!!!

Erectile Dysfunction

Oftentimes ED is not a psychological or emotional problem. Many times it is because of decreased blood flow to vital parts of your body. Come see the vascular specialists at HAVI for a confidential appointment.

Enhanced External Counter Pulsation (EECP)

EECP is a non-surgical, mechanical procedure that can reduce the symptoms of angina pectoris, by increasing coronary blood flow in areas of the heart that lack blood flow.

Cardiac PET

HAVI is proud to provide our Polk county patients with the only dedicated Cardiac PET machine in the county.

A heart PET scan can detect whether areas of your heart muscle are receiving enough blood, if there is heart damage or scar tissue in the heart, or if there is a build up of abnormal substances in the heart muscle.

Endovenous Ablation

Varicose vein treatment, also known as endovenous ablation, uses radiofrequency or laser energy to cauterize and close varicose veins in the legs. It may be used for cosmetic purposes, but it is most commonly used to help alleviate related symptoms such as aching, swelling, skin irritation, discoloration or inflammation. Endovenous ablation is safe, less invasive than conventional surgery, and leaves virtually no scars.
