We report two cases of acquired coronary fistula in whom fistula flow and
surgical repair were evaluated intraoperatively by contrast
echocardiography. Surgical repair was carried out through the left atrium
because of the associated surgical procedure on the mitral valve. Contrast
echocardiography allowed easy identification of the fistula openings in the
left atrium and intraoperative control of the efficacy of the surgical
closure. Contrast echocardiography is an ideal tool for the intraoperative
diagnosis of effective interruption of a coronary fistula.
