What this trial studies

This pilot clinical trial aims to evaluate the effectiveness of cryoablation of intercostal nerves in reducing pain and opioid consumption in patients undergoing minimally invasive mitral valve surgery. The study is designed as a single-center, prospective, randomized trial with a 1:1 allocation ratio. Participants will be monitored for pain levels using the Visual Analog Scale (VAS) and for their opioid analgesic consumption post-surgery. The findings will provide preliminary data to inform a larger future trial.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for minimally invasive mitral valve surgery who can provide informed consent.

Not a fit: Patients who are pregnant, have chronic pain conditions, or are on certain medications that affect pain perception may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative pain and reliance on opioid medications for patients undergoing minimally invasive mitral valve surgery.

How similar studies have performed: While this approach is innovative, similar studies on nerve cryoablation for pain management have shown promising results, indicating potential for success.
