title: [Prolonged contrast infusion echocardiography with hydrogen peroxide].
abstract: A new method of prolonged C-echo-CG with HP implies intravenous administration of 0.3% HP solution for continuous contrasting of right heart chambers for 5-20 minutes. A new technique of C-echo-CG was introduced in 277 patients with innocent cardiac murmur (93), interventricular septal defects (19), interatrial septal defects (26), open oval foramen (42), tricuspid regurgitation (56), pulmonary artery regurgitation (41). Prolonged C-echo-CG with HP was combined with respiratory stress tests. The technique is simple, more effective than short-term C-echo-CG, free of severe side effects and complications.
