Manobra intraoperatória guiada por ecocardiografia transesofágica para facilitar remoção de trombo intraventricular

Intra-cavitary thrombus size, mobility and friability are of great importance in deciding whether surgical removal is indicated. Thrombus characteristics may render surgical thrombectomy incomplete, a risk for catastrophic embolization. During de-airing of the heart, after removal of an intraventricular thrombus, filling the open ventricular cavity with blood serendipitously allowed trans-esophageal echocardiographic (TEE) visualization of undetected residual thrombi fragments. This experience leads us to advocate repeated filling and emptying of the left ventricle with blood, under TEE guidance, in order to facilitate complete removal of thrombotic material prior to ventriculotomy closure, and prior to weaning from cardiopulmonary bypass (CPB).
