[Minimally invasive video-assisted operations for heart disease]

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Minimally Invasive Techniques

Background:

• Minimally invasive cardiac surgery offers an alternative to conventional median sternotomy for mitral and tricuspid valve procedures.
• This study evaluates the institutional experience and outcomes of minimally invasive cardiac surgery.

Purpose of the Study:

• To assess the safety and feasibility of the minimally invasive approach for valve disease therapy.
• To report the results of minimally invasive mitral and tricuspid valve surgery at the institution.

Main Methods:

• A retrospective analysis of 52 patients undergoing minimally invasive cardiac surgery between November 2011 and March 2013.
• Procedures utilized right lateral minithoracotomy and femoral vessel cannulation for cardiopulmonary bypass.
• Follow-up data was collected prospectively and analyzed retrospectively.

Main Results:

• The study included 52 patients (63.5% female, mean age 60.9 years).
• Procedures involved mitral valve repair (85%), tricuspid valve repair (48%), atrial septal defect closure (15%), and atrial fibrillation cryoablation (50%).
• Zero hospital and 30-day mortality was observed, with low reoperation rates (3.8%) at follow-up.

Conclusions:

• Minimally invasive cardiac surgery via minithoracotomy is a safe and feasible routine method for treating valve disease.
• The technique shows comparable mortality and in-hospital morbidity to conventional approaches.
