How to Pronounce Coarctation
"The newborn was diagnosed with aortic coarctation and underwent surgical repair."
"In the cardiology clinic, they measured the degree of coarctation to determine treatment."
"Radiologic imaging confirmed a focal coarctation of the thoracic aorta."
Break it as /ˌkoʊˈɑːrktˌeɪʃn̩/ in US and /ˌkɔːˈɑːktəˌeɪʃn̩/ in UK; stress is on the third syllable in practice (arct) with final -ation. Start with a light preceding /ko/ or /kɔː/ cluster, then a strong /ɑːrk/ (American) or /ɑːk/ (British), followed by /teɪʃn̩/. Visualize “ko-ARK-tay-shn” with a prominent onset on ARK. MP3 audio references: you can check Pronounce or Forvo examples for medical terms to confirm the exact rhythm.
Common errors include misplacing the stress (shifting to CO-arctation) and mispronouncing the /t/ and /ʃ/ cluster in -ation as /ən/ or /ʃn/. Another error is the /ko/ vs /kɔ/ vowel mismatch between US and UK speakers, leading to a softer vs drawn-out initial syllable. To correct: emphasize the /ˌkoʊˈɑːrk/ (US) or /ˌkɔːˈɑːk/ (UK) onset, ensure the /t/ is a clear stop before /eɪʃn̩/. Use minimal pairs to lock the rhythm.
US tends to use /ˌkoʊˈɑːrkˌteɪʃn̩/ with a rhotic /r/ and a clear /t/ before /eɪ/. UK often features non-rhoticity and a slightly longer /ɔː/ in the first syllable, giving /ˌkɔːˈɑːktəˌeɪʃn̩/. Australian pronunciation is generally rhotic but may have a flatter /ɔː/ and a stronger /t/ emission; expect /ˌkɔːˈɑːktəˌeɪʃn̩/ with local vowel shifts. Always listen to regional medical diction to capture subtle vowel length and consonant timing.
The difficulty lies in the consonant cluster -ct- followed by -ation leading to multiple consonants in close proximity and the syllable with a secondary stress. The sequence /ˈkoʊˈɑːrk/ demands a robust /r/ and clean /t/ before the enduring /eɪʃn̩/. Also the nonintuitive spelling can mislead learners to misplace stress or replace /ɑːr/ with /ɑːrko/. Focusing on the three core phonemes /k/, /oʊ/ or /ɔː/, and /t/ before /eɪ/ will help you anchor the rhythm.
Coarctation has a pronounced stress pattern (secondary stress on -co- and primary on -ation), with all letters generally pronounced in normal speech. There are no silent letters in standard English pronunciation for this term. The main challenge is the interaction of /t/ and /eɪʃn̩/ and keeping the -tion syllable light but audible. Visualize the word as co-ARK-tay-shn, with steady, even timing through the -ation.

Coarctation comes from the Late Latin coarctatio, from coarctare meaning to compress, press together. The prefix co- (together) plus arctare (to compress) reflects the root idea of bringing parts together to squeeze. The term entered medical vocabulary through Latinized forms in the medieval to modern era to describe congenital and acquired constrictive lesions, especially of arteries. The first known uses appear in anatomical and surgical writings from the 18th and 19th centuries as surgeons codified congenital heart defects. Over time, coarctation expanded beyond general “narrowing” to a precise clinical diagnosis—coarctation of the aorta—so that the word now functions both as a descriptive pathology and a specific condition name in cardiology. Modern usage emphasizes the anatomic location (thoracic aorta commonly), the hemodynamic consequences, and treatment implications, while etymology underscores its original sense of “together-pressed” anatomy. The term remains entrenched in medical vocabulary, with standard pronunciation in English emphasized by the stress on the third syllable and a clear final -tion sound.
