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.
