title: "Isolated" diastolic dysfunction in left ventricular outflow tract obstruction.
abstract: We sought to investigate the prescence of "isolated" diastolic disease, defined as reduced long-axis early diastolic velocity with normal systolic velocity, in 21 young patients with left outflow tract obstruction. Most patients had depressed systolic velocities despite normal ejection fractions. The close relations amond long-axis velocities suggest isolated diastolic disease is unlikely.
