A few years ago, the idea of receiving a hepatitis C donor heart or living with a mechanical pump seemed closer to science fiction than medicine. Yet today, these are routine practices in cardiology. Now, a U.S.-based heart transplant specialist says even more radical treatments are on the horizon.
Dr. Dmitry Yaranov, director of the Advanced Heart Failure Program at Baptist Memorial Hospital in Memphis, Tennessee, and better known on Instagram as @heart_transplant_doc, recently outlined what he calls the “crazy future of heart care” in a viral post. His message: procedures that sound wild today may soon define tomorrow’s treatment of heart disease.
Lab-grown hearts: a new lease of life
According to Dr. Yaranov’s post, one of the most groundbreaking possibilities is lab-grown hearts. Scientists are experimenting with creating heart tissue and even entire organs from a patient’s own cells. This could eliminate the risk of rejection and reduce dependence on donor waitlists.
Gene editing: repairing the heart before damage begins
The cardiologist highlighted the potential of gene editing tools such as CRISPR, which could allow doctors to prevent heart failure or fix inherited cardiac conditions long before they become life-threatening. Preventive intervention at the genetic level could redefine how medicine approaches cardiovascular care.
Pig hearts for humans: crossing species boundaries
Dr. Yaranov also pointed out advances in xenotransplantation. With the right gene modifications, pig hearts could be transplanted into humans when donor organs are scarce. While it sounds extraordinary, such transplants have already been attempted, marking a new frontier in organ replacement.
mRNA therapies: beyond vaccines
The same mRNA technology that powered COVID-19 vaccines is now being explored in cardiology. Researchers are testing whether it can regrow blood vessels and repair damaged heart muscle, offering new hope for patients with chronic heart disease.
Nervous system therapy: rewiring the body
Another futuristic approach involves using small devices to “rewire” the nervous system. By calming the body’s stress signals, these treatments could improve heart function in ways that pills alone cannot achieve.
Tomorrow’s medicine
“It may sound crazy now. But so did the defibrillator, the stent, and the transplant,” Dr. Yaranov wrote in his Instagram post. He emphasized that the future of cardiology is not decades away—it is already being built in labs and clinical trials across the world.
Dr. Yaranov, a Russian-born cardiologist specializing in advanced heart failure and transplants, has built a following online by breaking down complex medical science into engaging, relatable content.
