Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients scheduled for mitral valve surgery with a mean pulmonary artery pressure of 55 mmHg or higher.

Probably not a fit

Patients who may not benefit include those with severe left ventricular dysfunction, hemodynamic instability, or contraindications to the study interventions.

What this trial studies

This study investigates the effects of inhaled versus intravenous milrinone in patients with severe pulmonary hypertension who are scheduled for cardiac surgery. Milrinone is commonly used as an inotropic agent and pulmonary vasodilator, but intravenous administration can lead to systemic hypotension and increased need for other vasoactive medications. By comparing these two methods of administration, the study aims to determine which approach is more effective and safer for patients undergoing mitral valve surgery. The study will involve patients with a specific mean pulmonary artery pressure as assessed by preoperative echocardiography.

Why it matters

Potential benefit: If successful, this study could lead to improved management of pulmonary hypertension in patients undergoing cardiac surgery, potentially reducing complications and improving outcomes.

How similar studies have gone: While the use of milrinone is established, this specific comparison of inhaled versus intravenous administration in this patient population is novel and has not been extensively tested.
