Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • Aortic dissection is a life-threatening condition with high mortality.
  • Optimal arterial cannulation for cardiopulmonary bypass in type-A aortic dissection remains debated.
  • Current methods like femoral, axillary, or innominate artery cannulation carry risks such as malperfusion and atheroembolism.

Purpose of the Study:

  • To introduce and describe transapical aortic cannulation (TAC) as an alternative method for establishing cardiopulmonary bypass.
  • To highlight the potential benefits of TAC in managing acute type-A aortic dissection.

Main Methods:

  • Transapical aortic cannulation involves inserting an arterial cannula through the left ventricular apex and aortic valve into the sinus of Valsalva.

  • Trans-oesophageal echocardiography guidance is crucial for accurate cannula placement.
  • This technique establishes antegrade arterial flow for cardiopulmonary bypass.

    • Main Results:

    • TAC is a quick procedure for establishing cardiopulmonary bypass.
    • It facilitates a more physiological antegrade arterial flow.
    • TAC is the only method that guarantees perfusion of the true lumen in aortic dissection.

    Conclusions:

    • Transapical aortic cannulation is a promising and potentially safer alternative for cardiopulmonary bypass in aortic dissection.
    • This technique may mitigate risks associated with traditional cannulation sites.
    • Further research and adoption of TAC could improve patient outcomes in acute aortic dissection.
