Cardiac surgery causes a series of disturbances in human physiology. The correction of systemic hemodynamic variables is frequently ineffective in improving microcirculatory perfusion and delivering oxygen to the tissues. We present the case of a 52-year-old male submitted to mitral valve replacement (metallic valve) and subaortic membrane resection. Sublingual microcirculatory density and perfusion were evaluated using a handheld CytoCam camera before surgery and in the early postoperative period. In this case, systemic hemodynamic variables were compromised despite an actual improvement in the microcirculatory parameters in comparison to the preoperative evaluation, possibly due to the correction of the structural cardiac defects.
心脏手术会引起一系列人体生理紊乱。纠正全身血液动力学变量通常无法有效改善微循环灌注和向组织输送氧气。我们报告了 1 例 52 岁男性患者，行二尖瓣置换术（金属瓣）和主动脉瓣下膜切除术。在术前和术后早期使用手持式 CytoCam 相机评估舌下微循环密度和灌注。在这种情况下，尽管与术前评估相比，微循环参数实际上有所改善，但全身血液动力学变量仍受到影响，这可能是由于结构性心脏缺陷的纠正。
