Minimally invasive reoperative aortic valve replacement
The operative mortality associated with repeat heart valve surgery is supposedly higher than the mortality associated with the primary operation. However, controversy still surrounds the risk factors and optimal surgical approach for patients requiring repeat cardiac surgery, particularly for those requiring aortic valve replacements (AVR). While the standard approach generally utilizes full sternotomy and peripheral cannulation, alternative approaches such as minimally invasive sternotomy may play an increasingly important role in this field. This study compares the advantages and disadvantages of a minimally invasive approach in redo AVR with the standard approach, highlighting difficulties and potential solutions.
