Randomized Controlled Trial Comparative StudyDirect observation of the human microcirculation during cardiopulmonary bypass: effects of pulsatile perfusion.
Possible benefits of pulsatile perfusion during cardiopulmonary bypass often are attributed to enhanced microvascular flow. However, there is no evidence to support this in humans. Therefore, the authors assessed whether pulsatile perfusion alters human microvascular flow. ⋯ Pulsatile perfusion does not alter human microvascular perfusion using standard equipment in routine cardiac surgery. Changes in pulse pressure or energy-equivalent pressure bear no obvious relationship with microcirculatory parameters.

Comparative StudyIntraoperative assessment of mitral valve area after mitral valve repair: comparison of different methods.
In the present study, 3 different methods to measure the mitral valve area (MVA) after mitral valve repair (MVRep) were studied. Data obtained immediately after repair were compared with postoperative data. The objective was to determine the feasibility and correlation between intraoperative and postoperative MVA data. ⋯ The MVA recorded immediately after valve repair, using PHT, correlated and agreed with MVA data obtained in the postoperative period. These results contrast with previously published data and could highlight the impact of hemodynamic function during the assessment of MVA.
