Area of Science:

  • Cardiovascular Surgery
  • Surgical Devices
  • Biopsy Techniques

Background:

  • Left ventricular biopsies are crucial for diagnosing cardiac conditions.
  • Current biopsy methods can be complex and time-consuming during surgery.

Purpose of the Study:

  • To introduce a simple, one-handed device for performing left ventricular biopsies.
  • To evaluate the safety and efficacy of this new biopsy method during open-heart surgery.

Main Methods:

  • A novel, gun-shaped automatic device was employed for tissue sampling.
  • The device allows for rapid biopsies (seconds) at any point during surgery.
  • Biopsies were performed transmurally, yielding approximately 18 mm3 of tissue.

Main Results:

  • The device was successfully used in 20 patients undergoing coronary artery revascularization.
  • All left ventricular biopsies were technically successful.
  • No complications were reported following the biopsy procedures.

Conclusions:

  • This automatic device offers a simple and safe method for left ventricular biopsies.
  • The technique is efficient and can be integrated seamlessly into open-heart procedures.
  • Further adoption may improve diagnostic capabilities in cardiac surgery patients.
