A 58 years old lady underwent mitral valve replacement eight months ago. Today came with restlessness and weakness and dyspnoea. I am looking after her from last twenty-five years for RHD, MS, AF with occasional CHF. But never like today's status.

X-ray chest shows Huge cardiomegaly, TLC, Sugar are normal. look at ECHO and X-ray chest. What happened after prosthetic valve replacement?
