Head to head comparison of dobutamine–transoesophageal echocardiography and dobutamine–magnetic resonance imaging for the prediction of left ventricular functional recovery in patients with chronic coronary artery disease

103 patients with chronic coronary artery disease and dysfunctional but potentially viable myocardium who cannot be accurately evaluated by transthoracic echocardiography due to a poor acoustic window. 52 patients with successful revascularization and an angiographically controlled open target vessel were evaluated at follow-up.

Dobutamine-transoesophageal echocardiography (dobutamine-TEE) at rest and low-dose (5, 10 microg dobutamine x min(-1) x kg(-1))

Dobutamine-magnetic resonance imaging (dobutamine-MRI) at rest and low-dose (5, 10 microg dobutamine x min(-1) x kg(-1))
