The old man’s lips were blue-grey ( cyanosis ), his nostrils flared like a spooked horse ( dyspnea ), and his cheeks bore a faint, waxy flush that Elías remembered from his mentor: mitral facies , a pink-purple stain from low cardiac output.

He then examined the neck veins. With the silver penlight from his pocket, he traced the jugular pulse. It rose in a giant, cannon-like ‘a’ wave— atrial kick against a stenotic valve .
