Summary
Minimally invasive mitral valve surgery using a transthoracic clamp technique shows low mortality and morbidity. This approach offers excellent cosmetic results and avoids thoracic wound infections, with outcomes comparable to traditional methods.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Cardiac Surgery
Background:
- Reports on a 7-year experience with minimally invasive mitral valve operations.
- Focuses on the transthoracic clamp technique for mitral valve surgery.
Purpose of the Study:
- To review morbidity and mortality rates.
- To assess echocardiographic follow-up results.
- To evaluate the efficacy of the transthoracic clamp technique in minimally invasive mitral valve surgery.
Main Methods:
- 241 patients underwent minimally invasive mitral valve surgery via right thoracotomy.
- Utilized the transthoracic clamp technique.
- Included 199 reconstructions and 42 valve replacements.
Main Results:
- 30-day mortality was 3.3% (8 patients).
- Mean follow-up was 30 months, with 76-month freedom from reoperation at 96.2%.
- Actuarial survival at 76 months was 90.7%; no thoracic wound infections occurred.
Conclusions:
- The transthoracic clamp technique is reproducible for minimally invasive mitral valve surgery.
- Associated with low mortality, morbidity, and excellent cosmesis.
- Midterm outcomes are comparable to conventional open-heart surgery.
