Why the study?
Does cardiopulmonary bypass cause transient depression of right ventricular function in patients with normal preoperative cardiac function?
Does cardiopulmonary bypass cause transient depression of right ventricular function in patients with normal preoperative cardiac function?
Cardiopulmonary bypass induces a transient, reversible depression of right ventricular systolic function that resolves within 24 hours without adverse consequences in patients with normal baseline cardiac function.

May warrant brief post-CPB RV monitoring in normal hearts; leaves open impact on outcomes or need for intervention in higher-risk patients.
