Cardioscopy: potential applications and benefit in cardiac surgery

Area of Science:

• Cardiovascular Surgery
• Medical Imaging
• Surgical Technology

Background:

• Cardioscopy is not yet a routine procedure in most open-heart surgery units.
• Increasing use of cardioscopy suggests potential benefits in surgical safety and accuracy.

Purpose of the Study:

• To evaluate the utility and safety of cardioscopy in open-heart surgery.
• To assess cardioscopy's role in various surgical indications and its impact on procedure control and documentation.

Main Methods:

• Cardioscopy was performed on 100 patients between January 1996 and December 1997.
• Indications included septal resection, aortic valve evaluation, foreign body removal, VSD inspection, paravalvular leak identification, diagnostics, and surgical education.
• A 5 mm rigid or flexible cardioscope was inserted via the ascending aorta, aortic valve, or tricuspid valve during cardioplegic arrest.

Main Results:

• No complications occurred during cardioscopy procedures.
• Excellent visualization of intracardiac structures was achieved for septal resection, VSD inspection, and valve assessment.
• Intracardiac foreign bodies and tumors were successfully removed; paravalvular leakages were identified.
• Cardioscopy facilitated accurate assessment of surgical repairs and provided diagnostic information.

Conclusions:

• Cardioscopy is a valuable supporting technique for identifying intracardiac structures and controlling surgical procedures.
• It aids in documenting valve pathology and serves as an educational tool for surgical teams.
• The technique is easy to handle, does not increase operative risk, and may enable future minimally invasive approaches.
