Conversion from ministernotomy to full sternotomy occurred in 5% of aortic valve replacement patients. Factors like older age and comorbidities contributed, but the conversion group had no mortality, unlike the overall ministernotomy group.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Minimally Invasive Cardiac Surgery

Background:

  • Ministernotomy approaches for Aortic Valve Replacement (AVR) aim to reduce invasiveness.
  • Conversion to full sternotomy during AVR can be necessary in complex cases.

Purpose of the Study:

  • To analyze the incidence, contributing factors, and outcomes of converting from ministernotomy to full sternotomy during AVR.
  • To identify strategies for minimizing conversion rates in AVR procedures.

Main Methods:

  • Retrospective analysis of 100 consecutive patients undergoing AVR via ministernotomy.
  • Evaluation of patient demographics, surgical techniques, and intraoperative/postoperative data.
  • Comparison of outcomes between patients requiring conversion and those not converted.

Main Results:

  • Conversion to full sternotomy was required in 5% of AVR cases.
  • Older age, aortic fragility, diffuse coronary disease, renal failure, and left ventricular insertion were associated with conversion.
  • Despite longer cardiopulmonary bypass times and hospital stays, the conversion group experienced no mortality, compared to 4.2% in the overall ministernotomy population.

Conclusions:

  • Conversion to full sternotomy in AVR, while associated with increased resource utilization, does not appear to increase mortality.
  • Careful patient selection and surgical technique are crucial to minimize the need for conversion.
  • Further research into alternative surgical strategies may help reduce conversion rates.
