Temporary Biventricular Pacing

Hemodynamic Effect of Temporary Biventricular Pacing After Mitral and/or Tricuspid Valve Surgery in Patients With Preoperative Biventricular Dysfunction

The hypothesis of this study is that temporary biventricular pacing will improve hemodynamic performance in patients with right ventricular dysfunction after open cardiac chamber cardiac surgery.

Inclusion Criteria:

• mitral or tricuspid valve surgery patients identified as having preoperative Right Ventricular dysfunction and Left Ventricular Ejection Fraction less than 45 percent

Exclusion Criteria:

• Patients with in-situ biventricular pacemakers
• Pregnant or lactating females
