Restrictive left ventricular filling in hypereosinophilic syndrome as a result of partial cavity obliteration by an apical mass: a strain/strain rate study

Abstract

We present a case of hypereosinophilic syndrome with a large apical mass, which markedly reduced end-systolic left ventricular cavity volume. Standard blood pool Doppler findings showed a restrictive filling pattern. However, ultrasound-derived regional strain rate and strain parameters suggested that wall deformation was not compromised, inferring that the restrictive filling pattern in this case was solely as a result of the reduction in end-systolic cavity size.
