How to Pronounce Tricuspid Regurgitation

Tricuspid regurgitation is pronounced "try-KUS-pid reh-gur-jih-TAY-shun." The stress falls on the second syllable of tricuspid (KUS) and the last syllable of regurgitation (TAY). If you break it down, it's easier to say each part separately and then put them together.

Tricuspid comes from Latin roots: "tri" means three, and "cuspid" means pointed or having cusps (flaps). So tricuspid literally means "three-pointed" or "three-cusped," which describes a valve in the heart that has three flaps.

Regurgitation comes from Latin and means "to surge back" or "to flow backward." In medical language, it describes blood flowing the wrong direction, opposite to how it normally should move through the heart.

The word breaks down like this: try-CUS-pid reg-ur-gi-TA-tion. Tricuspid has three syllables, and regurgitation has four syllables, making seven syllables total in the full term.

Many people stress the wrong syllable in regurgitation—they say "REG-ur-gi-tay-shun" instead of "reh-gur-jih-TAY-shun." Remember that the stress belongs on the second-to-last syllable (TAY), not the first one.

Yes, it's often abbreviated as "TR" in medical writing. You would say it as "T-R" (the letters) rather than trying to pronounce it as a word.

You might hear "bicuspid," which uses the same root but means "two-cusped" instead of three. The "cuspid" root appears in dental terms too, since cuspid teeth (canines) are pointed like cusps on heart valves.

You might hear a doctor say, "The patient was referred to cardiology because of tricuspid regurgitation found on the ultrasound." This simply means the imaging test identified this valve condition, without explaining why or what happens next.
