With permission from the patient to post, today I performed one of the more unusual and challenging operations of my career. To understand why, you have to know this patient’s remarkable history.

Her journey began when she was in her mid-30s. She underwent her first heart operation in New York, where an attempt was made to repair her mitral valve. Unfortunately, that repair ultimately failed.

About two years later, she underwent a second operation in Tennessee. This time, her mitral valve was replaced with a bioprosthetic, or tissue, valve.

Unfortunately, that valve had limited durability. After she subsequently moved to the Lehigh Valley, she was admitted with heart failure because the tissue valve had deteriorated.

That’s when our paths first crossed.

I performed her third heart operation, replacing the failed tissue valve with an On-X mechanical mitral valve. Given her age, her history of early bioprosthetic valve failure, and the need to avoid yet another operation, a durable mechanical valve made sense.

Mechanical valves are extremely durable, but that durability comes with an important tradeoff: they require lifelong anticoagulation with warfarin.

And for 14 years, that strategy worked.

Her mechanical valve continued to function well.

But then her medical circumstances changed dramatically.

She developed multiple hemorrhagic strokes, bleeding within the brain, and was diagnosed with cerebral amyloid angiopathy, placing her at substantial risk for additional intracranial bleeding.

Suddenly, we were faced with an extraordinary dilemma.

The valve was working. But the anticoagulation required to safely live with that valve had become unacceptably dangerous.

So, 14 years after I performed her previous operation in the Lehigh Valley, she came back to me, this time at Jefferson Einstein Montgomery Hospital, for her fourth open-heart operation.

Today, we removed the functioning On-X mechanical valve and replaced it with a bioprosthetic tissue valve.

Think about that for a moment.

Her first operation attempted to save her native valve. Her second replaced it with a tissue valve. Her third replaced that failed tissue valve with a mechanical valve for durability. And now, 14 years later, her fourth operation required us to go back to a tissue valve because anticoagulation had become too dangerous.

The mechanical valve didn’t fail. The patient’s medical circumstances changed.

And perhaps that’s the most important lesson from this case.

There is no single heart valve that is perfect for every patient at every stage of life. We have to balance durability, the possibility of another intervention, the risks of anticoagulation, age, medical conditions, and most importantly, the individual patient.

That’s why valve selection is fundamentally an individualized, shared decision.

Sometimes heart surgery is about repairing something that’s broken.

And sometimes it’s about recognizing that the treatment that was right 14 years ago may no longer be the right treatment today.
