How to Pronounce Prosthetic Valve Thrombosis

Say it like this: pros-THET-ik VALV throm-BOH-sis. The stress falls on the second syllable of 'prosthetic' (THET) and the third syllable of 'thrombosis' (BOH). If you say it slowly at first, it becomes much easier to remember the rhythm.

'Prosthetic' comes from Greek and means something that is artificial or man-made—in this case, an artificial heart valve that replaces a damaged natural valve. You'll hear 'prosthetic' used for artificial limbs and joints too.

'Thrombosis' comes from the Greek word 'thrombos,' which means a blood clot. In medical language, thrombosis refers to the formation or presence of a blood clot inside a blood vessel, and it shows up in many heart and circulation terms.

'Valve' is a structure that acts like a one-way gate, allowing fluid to flow in one direction but not backward. In your heart, valves make sure blood flows the right way through the chambers.

It's when a blood clot forms on or around an artificial heart valve. Think of it as a clot blocking or threatening to block the artificial valve that's supposed to help blood move through the heart.

Broken into syllables, it's: pros-THET-ic (3 syllables) + valve (1 syllable) + throm-BO-sis (3 syllables), for a total of 7 syllables. Saying each syllable slowly helps you get the whole phrase right.

Many people stress the wrong syllable in 'thrombosis'—they say throm-boh-SIS (stress on the last syllable) instead of throm-BOH-sis (stress on the middle syllable). Remember: the stress moves toward the middle of the word.

'Thrombosis' shares its root with words like 'thromboembolism' (a clot that travels), 'thrombotic' (relating to clots), and 'antithrombotic' (something that prevents clots). All of these use 'thrombo' to refer to blood clots.

You might hear: 'The patient was admitted to the hospital with a diagnosis of prosthetic valve thrombosis.' This sentence simply tells you that a clot has formed on an artificial valve and that's why the person came to the hospital.
