Memorial Tributes

"It is with heavy heart and deep sadness that I announce the death of our classmate Dr. David T. Hart, who passed away yesterday, January 19th, 2014.

David Hart enrolled at the Federal Government College in Port Harcourt at the age of 10 and graduated at the age of 15.  As a precocious student, he was admitted directly to study Medicine at the prestigious medical school, the University of Ibadan. Despite his young age, he weathered the academic rigors and graduated ‘on-time’ to become a medical doctor at the tender age of 21. We graduated together in the class of 1988 from this great institution.
After internship and a mandatory year of national service, he headed to Great Britain where he spent the next five years in post-graduate training in Medicine. He distinguished himself, and after reaching the glass ceiling, he made a move to the United States.

On arrival to the American shores, he blazed through the system like a hero. He did his residency in Internal Medicine at St. Luke’s-Roosevelt Hospital Center in New York.  He was an excellent resident, and he advanced to a fellowship in Cardiology at the same institution. He further sub-specialized in electrophysiology. He was Board Certified in Internal Medicine, Cardiovascular Diseases and Clinical Electrophysiology.

He had 23 peer-reviewed publications.  These include:  “Successful Ablation of Focal Left Atrial Tachycardia Using Stereotaxis  Niobe Remote Magnetic Navigation System,” published in Europace  and “Comparison of Computed Tomographic Imaging with Intraprocedural  Contrast Esophagram: Implications for Catheter Ablation of Atrial Fibrillation,” published in Heart Rhythm (USA).

He was an Assistant Professor of Cardiology and Electrophysiology at Ohio State University College of Medicine until his untimely death. He was only 47 years old. He was a husband and father and is survived by his wife Karen and his three children. We will continue to remember him, as he left us some memorable moments. I have attached one of those moments to this piece.


May his gentle soul rest in perfect peace.

Abraham A. Ariyo, MD, MPH, FACC.

"I just did a search for Dr. Hart and saw this sad information.  He was amazing at what he did, and I hope that his kids and wife find peace in knowing that this man was so very well respected."

This tribute was added by Monisola Oni on 19th January 2017

"Although I have never met them, I feel like I know David's family just from conversations with the Akinola's. I apologize for the rather long narrative.
I am writing this with the hope that David's kids will know what an amazing guy he was.
We went to the same Medical School but I was a few years his junior, so I barely knew him.
We were on the same flight back to the US from Nigeria in January 2011 and ended up sitting right next to each other.
After introductions, we realized we had UCH in common and I remembered his name.
He was an Electrophysiologist in the process of getting an MBA. He explained how he felt he needed to keep learning and growing.
I remember feeling both inspired and unaccomplished at the same time. I said to him that  I was "just" an Internist.
I will never forget his response - "there is no such thing as just an internist". I was valuable and made a difference and I was never to refer to myself as such again.
I had visited my 80 year old Mom who was getting frail and I tearfully mentioned that I wondered how many more times I would get to see her.
He was returning from a cousin's funeral(about the same age as him). He had also lost his Mother a few years earlier.
He told me never to take my Mother(and other loved ones) for granted and to cherish every opportunity I get to spend time with her.

In just a few short hours(we both had different connecting flights in Amsterdam),  he made such a huge impression on how I viewed myself and how I manage my relationships even today. He also inspired a brand new desire in me for life long learning.
May His soul continue to RIP and may God continue to comfort and provide for his family.
Monisola Oni."

I am still baffled by this every time I think of you! I think so often of how you'd scold me and tell me about the planning of my future and don't be frivolous, you'd be happy to know that I am passing the same wisdom down to others now.

"We join in commemoration of the wonderful, though all too brief, life of David Hart

God has a plan and purpose to everything, even in situations too difficult to understand

Clearly, David's life and legacy are inspirational to those who were blessed to call him their physician, friend, colleague and mentor, or any combination thereof
And most especially, to his wife Karen, their children Karibi, Sonari & Damiete, and all his relatives, David/Dad will be with them in the loving imprint he left in their hearts

David represents so much good in the lives of others, and this wonder and grace are timeless

Let's continue to honor his life as we share our love for those around us, in our daily interactions, much like David did

Rest in perfect peace, David
God loves you best

Albert & Olive Todd & Family"

"I'm very sorry for your sad loss, and although I don't know you, and I didn't know David, I hope that you will accept my expression of deepest sympathy to you in your loss of your beloved David. This past Sept, my precious and beloved Mom died, and I would like to share with you what continues to bring me comfort that I hope will give you a measure of comfort too. I think about that my beloved Mom isn't suffering and that means a lot! And I have the hope to see and be with her again through the resurrection to welcome her back to life and be able to give her a hug again. I realize that our grief isn't the same, and I hope that you will not be offended by my writing to you at this time. (Acts 24:15; Eccl. 9:11b; James 1:13; Isa. 33:24; Rev. 21:4, 5; Psalm 37:10, 11, 29) Take care, Sincerely, Cindy Boyer"
