Outcome Measures

Primary Outcomes (1)

  • mean early diastolic mitral annular plane velocity (E')

    (E'lateral + E'medial)/2; by TDI and STE

    immediately during echo exam while in the operating room; i.e. preinduction (TTE AP 4C), postinduction (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view), post-CPB (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view)

Secondary Outcomes (10)

  • mean late (atrial) diastolic mitral annular plane velocity (A')

    immediately during echo exam while in the operating room; i.e. preinduction (TTE AP 4C), postinduction (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view), post-CPB (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view)

  • mean early diastolic mitral annular plane velocity/mean late (atrial) diastolic mitral annular plane velocity (E'/A')

    immediately during echo exam while in the operating room; i.e. preinduction (TTE AP 4C), postinduction (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view), post-CPB (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view)

  • mean early diastolic mitral inflow velocity/mean early diastolic mitral annular plane velocities; (E/E')

    immediately during echo exam while in the operating room; i.e. preinduction (TTE AP 4C), postinduction (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view), post-CPB (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view)

  • Peak systolic mitral annular velocity (S')

    immediately during echo exam while in the operating room; i.e. preinduction (TTE AP 4C), postinduction (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view), post-CPB (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view)

  • Displacement by Mitral Annular Plane Systolic Excursion (MAPSE)

    immediately during echo exam while in the operating room; i.e. preinduction (TTE AP 4C), postinduction (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view), post-CPB (TTE AP 4C view, TEE ME 4C view, TEE dTG LAX view)

  • +5 more secondary outcomes

Study Arms (3)

TTE Apical 4 Chamber View

OTHER

Patients will receive TTE apical 4chamber echo examinations prior to induction and after induction

Other: TTE Apical 4 Chamber View

TEE dTG View

OTHER

Patients will receive TEE deep transgastric echo examinations after induction and after cardiopulmonary bypass induction (paced at 80, 100, and 120 bpm)

Other: TEE dTG View

TEE ME 4C View

OTHER

Patients will receive TEE midesophageal 4chamber echo examinations after induction and after cardiopulmonary bypass induction (paced at 80, 100, and 120 bpm)

Other: TEE ME 4C View

Interventions

We will measure a number of echocardiography parameters by TTE (apical 4 Chamber View) prior to and after induction

TTE Apical 4 Chamber View

We will measure a number of echocardiography parameters by TEE (dTG View) prior to cardiopulmonary bypass and after cardiopulmonary bypass (atrially paced at 80, 100, and 120 bpm)

TEE dTG View

We will measure a number of echocardiography parameters by TEE (ME 4C View) prior to cardiopulmonary bypass and after cardiopulmonary bypass (atrially paced at 80, 100, and 120 bpm)

TEE ME 4C View
