Diastolic dysfunction and sepsis: the devil is in the detail

Diastolic dysfunction is the consequence of impaired left ventricular relaxation, decreased recoil and decreased ventricular compliance.¹ Before the era of tissue Doppler imaging (TDI), pulmonary vein Doppler imaging in conjunction with transmitral Doppler, was a major tool in identifying diastolic dysfunction, also in septic shock patients.² Pulmonary vein Doppler assessment with a systolic (S) < diastolic (D) flow velocity supports the finding of elevated left ventricular filling pressures in a euvolaemic patient.
