Brief Summary

Right heart failure during cardiac surgery is associated with increased perioperative morbidity and mortality. In this context, it is imperative to develop simple diagnostic tools to detect right heart failure. The purpose of this observational study is to determine if ultrasound Doppler of the femoral vein can detect and predict right ventricular failure after cardiac surgeries requiring cardiopulmonary bypass. It is expected that an elevated pulsatility of the femoral vein before the induction of general anesthesia is associated with perioperative right heart failure.

Outcome Measures

Primary Outcomes (1)

  • Determine the prevalence of an elevated pulsatility of the femoral vein on Doppler ultrasound before the induction of general anesthesia

    An elevated pulsatility on Doppler ultrasound is defined as a biphasic signal of the femoral vein with a retrograde velocity \> 10 cm/s on a long axis view at an angle correction \< 60 degrees. If there's signs of cardiac modulation on the Doppler ultrasound, pulsatility index will be measured in long and short axis as followed : (maximal velocity - minimal velocity)/maximal velocity.

    Before induction of anesthesia to day 1 postoperatively at the intensive care unit

Secondary Outcomes (10)

  • Determine the association between an elevated femoral vein pulsatility and diastolic or systolic right ventricular failure, before and after cardiac surgery and at the intensive care unit

    Before induction of anesthesia to day 1 postoperatively at the intensive care unit

  • Determine the association between an elevated femoral vein pulsatility and the intracardiac pressures of the right heart cavities and the pulmonary artery

    Before induction of anesthesia to day 1 postoperatively at the intensive care unit

  • Determine the association between the prevalence of an elevated femoral vein pulsatility and the portal vein pulsatility

    Before induction of anesthesia to day 1 postoperatively at the intensive care unit

  • Determine the impact of positive-pressure ventilation on the femoral vein pulsatility

    After induction of anesthesia and before cardiopulmonary bypass.

  • Determine the association between a preoperative elevated femoral vein pulsatility and postoperative complications.

    Immediate postoperative to Day 1 postoperatively at the intensive care unit

  • +5 more secondary outcomes
