Transesophageal Echocardiography in Comparison with Magnetic Resonance Imaging in the Diagnosis of Pulmonary Vein Stenosis after Radiofrequency Ablation Therapy

TEE Doppler measurements can be reliably used to detect or exclude significant pulmonary vein stenosis if the diagnosis is restricted to a combination of elevated peak velocity (≥ 110 cm/s) with turbulence and little flow variation.
