Minimally Invasive Approach for Redo Mitral Valve Surgery: A True Benefit for the Patient
Key result
Minimally invasive redo mitral valve surgery via right minithoracotomy was associated with a 5.1% mortality rate and normal valve function at 3 months.
Why the study?
Does a minimally invasive approach via right minithoracotomy improve safety and feasibility in patients undergoing redo mitral valve surgery?

Implication
May support right minithoracotomy in selected redo mitral cases; leaves open need for comparative trials before wider use.

Structured PICO
Does a minimally invasive approach via right minithoracotomy improve safety and feasibility in patients undergoing redo mitral valve surgery?
P
Population
39 patients (mean age 59, 59% female) undergoing redo mitral valve surgery via a right minithoracotomy, followed for 3 months.
E
Exposure
Minimally invasive redo mitral valve surgery via right minithoracotomy, using femoro-femoral cannulation and port access technique (or deep hypothermia and ventricular fibrillation for patients with prior CABG).
C
Comparator
Overall series of 394 patients undergoing mitral valve repair or replacement via right minithoracotomy (for surgical times).
O
Outcome
Mortality, surgical times (time of surgery and cross-clamp time), and complications.safety
Redo mitral valve surgery can be performed safely using a right minithoracotomy approach, avoiding resternotomy and yielding acceptable mortality and surgical times.
Cite This Study
Onnasch et al. (2008) conducted an observational in Redo mitral valve surgery (n=39). Right minithoracotomy vs. Overall series of minimally invasive mitral valve surgeries was evaluated on Mortality. Minimally invasive redo mitral valve surgery via right minithoracotomy was associated with a 5.1% mortality rate and normal valve function at 3 months.
