Tamponade

Question 1

Describe hepatic vein flow in restrictive cardiomyopathy, constrictive pericarditis and cardiac tamponade.

Answer 1

Remember RICE!
RESTRICTIVE – hepatic vein flow is reversed in INSPIRATION

CONSTRICTIVE and TAMPONADE (physiology is same) – with EXPIRATION, left ventricular filling increases limiting right ventricular filling and hepatic vein diastolic forward flow (D wave) decreases, with pronounced flow reversals
