Limited lower sternotomy for minimally invasive mitral valve replacement

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Minimally Invasive Procedures

Background:

• Traditional sternotomy for mitral valve surgery can lead to significant morbidity.
• Preservation of sternocostal articulations and internal thoracic arteries is desirable.
• Minimally invasive approaches aim to reduce surgical trauma and improve patient outcomes.

Purpose of the Study:

• To describe the minimally invasive limited lower sternotomy approach for mitral valve operations.
• To highlight the anatomical advantages and surgical benefits of this technique.

Main Methods:

• Surgical approach involving a limited lower sternotomy.
• Facilitation of aortic and atrial cannulation for cardiopulmonary bypass.
• Direct access to the mitral valve through the left atrium.

Main Results:

• Provides easy access to the left atrium for mitral valve procedures.
• Preserves sternocostal articulations and internal thoracic arteries.
• Avoids pleural cavity entry and costal cartilage resection.

Conclusions:

• The limited lower sternotomy is an effective minimally invasive approach for mitral valve surgery.
• This technique offers significant advantages in terms of anatomical preservation and surgical access.
