Changes in tissue Doppler characteristics in a patient with pulmonary atresia and intact ventricular septum.
Tissue Doppler measurements of the right and left lateral ventricular walls were made before and after perforation of the pulmonary valve using radiofrequency energy in a patient with pulmonary atresia and intact ventricular septum. The ratio of peak tissue velocity during rapid ventricular filling to atrial contraction increased for both atrioventricular valves after perforation of the pulmonary valve, and the patient was able to be weaned off prostaglandins without further intervention. Such measurements made using tissue Doppler may aid in the management of patients with pulmonary atresia and intact ventricular septum by predicting improvements in right ventricular relaxation.
