Outcome Measures

Primary Outcomes (2)

  • In-hospital post-operative atrial fibrillation

    Number of patients with post-operative atrial fibrillation within the first 5 days postoperatively or up to hospital discharge, whichever occurs first

    Within 5 days after index cardiac surgery

  • Hierarchical composite of all-cause death, ischemic stroke, systemic arterial embolism, unplanned hospital visit/readmission for cardiac reasons, and atrial fibrillation.

    Number of patients with a composite of all-cause death, ischemic stroke, systemic arterial embolism, unplanned hospital visit/readmission for cardiac reasons, and atrial fibrillation events, evaluated using the win ratio (thereby accounting for the difference in importance of these outcomes).

    Over the duration of the follow-up period to a common end date (mean follow-up of 5 years).

Secondary Outcomes (7)

  • Post-operative atrial fibrillation (POAF)

    Over the duration of the follow-up period to a common end date (mean follow-up of 5 years).

  • Length of post-operative in-hospital stay

    Over the duration of the follow-up period to a common end date (mean follow-up of 5 years).

  • Pericardial effusion without tamponade

    From index surgery completion to within 30 days of index surgery

  • Death

    From index surgery completion to within 30 days of index surgery

  • Ischemic stroke or systemic arterial embolism

    From index surgery completion to within 30 days of index surgery

  • +2 more secondary outcomes

Other Outcomes (5)

  • Number of patients with phrenic nerve injuries

    Within 30 days of index surgery

  • Number of patients with left pleural interventions

    Within 30 days of index surgery

  • Number of patients with esophageal injuries

    Within 30 days of index surgery

  • +2 more other outcomes

Study Arms (2)

Left Posterior Pericardiotomy Group

EXPERIMENTAL

The surgeon will perform a left posterior pericardiotomy during the patient's cardiac surgery.

Procedure: Left Posterior Pericardiotomy

No Posterior Pericardiotomy Group

NO INTERVENTION

The surgeon will not perform a posterior pericardiotomy during the patient's cardiac surgery.

Interventions

The surgeon will perform a left posterior pericardiotomy while the patient is on cardiopulmonary bypass. A soft channel drain will be put into place at an angle directed toward the posterior pericardium. The surgeon will grasp the pericardium and use cautery to make a 4- to 5-cm opening between the left inferior pulmonary vein and the diaphragm. The previously prepared channel drain is cut to the desired length and placed through the pericardiotomy along the diaphragm and into the pleural space.

Left Posterior Pericardiotomy Group

Eligibility Criteria
