Cardiac calcified amorphous tumor stuck in the aortic valve that mimicked a chameleon's tongue: report of a case.

A calcified amorphous tumor (CAT) is a rare intracardiac mass that carries a risk of embolism. We herein present the case of a club-shaped CAT that originated from the calcified mitral annulus. Echocardiography indicated a pendular motion of the mass and repeated entrapment by a stenotic aortic valve that was sustained for several beats, mimicking a chameleon's tongue. An emergency operation was performed because of the risk of embolism, as well as potential progression of cardiac failure due to worsening aortic valve stenosis. The histological findings were consistent with the diagnosis of a CAT. This report describes a case of an intracardiac tumor that showed unique motion like a chameleon's tongue.

Intraoperative continuous hemodiafiltration with selective venous drainage of ischemic limbs.

We report two cases of acute limb ischemia with threatened myonephropathic metabolic syndrome (MNMS) in which continuous hemodiafiltration (CHDF) was started before revascularization with selective drainage from the clamped femoral vein of ischemic limb and return of processed blood into the contralateral femoral vein. It was aimed to optimise the removal of metabolites which were produced by myolysis following reperfusion as well as to minimize the deviation of metabolites into the systemic circulation. Both cases had uneventful postoperative course without MNMS and the limbs were salvaged.
