Retrograde left ventricular catheterization in patients with an aortic valve prosthesis

Area of Science:

• Cardiovascular medicine
• Interventional cardiology
• Medical device evaluation

Background:

• Aortic valve prostheses require regular functional assessment.
• Existing methods for evaluating prosthetic valves carry risks or limitations.

Purpose of the Study:

• To evaluate the safety and efficacy of retrograde left ventricular catheterization for assessing aortic valve prostheses.
• To establish retrograde catheterization as an alternative to transseptal catheterization and left ventricular puncture.

Main Methods:

• Retrograde left ventricular catheterization was performed in 27 consecutive patients with aortic valve prostheses.
• Hemodynamic and angiographic data were collected to assess prosthetic valve, left ventricle, and mitral valve function.
• The technique was cautiously applied in patients with endocarditis or embolization.

Main Results:

• Successful retrograde catheterization and comprehensive evaluation were achieved in all 27 patients.
• No complications were observed, even in three high-risk patients.
• Minor interference with valve poppet movement was noted but did not impede evaluation.
• Hemodynamic data from the prosthesis and paraprosthetic defects were consistent.

Conclusions:

• Retrograde left ventricular catheterization is a safe and effective method for evaluating aortic valve prostheses.
• This approach provides a viable alternative to traditional transseptal techniques and left ventricular puncture.
• The study supports the routine use of retrograde catheterization for prosthetic valve assessment.
