Summary

Ultrasonic decalcification safely removes aortic and mitral annular calcification, improving valve seating and enabling larger valve placement. This technique resulted in zero paravalvular leaks or valve failures in 92 patients.

Area of Science:

  • Cardiovascular Surgery
  • Medical Devices
  • Biomedical Engineering

Background:

  • Heavy calcification of the aortic and mitral annulus complicates valve replacement surgery.
  • Improper valve seating due to calcification can lead to complications such as paravalvular leaks.

Purpose of the Study:

  • To evaluate the efficacy and safety of ultrasonic decalcification for annular debridement in patients undergoing valve replacement.
  • To assess the impact of ultrasonic debridement on valve seating, valve size, and clinical outcomes.

Main Methods:

  • Utilized ultrasonic energy with the CUSA device for annular debridement in 92 patients (90 aortic, 2 mitral) between 1987 and 1996.
  • Compared ultrasonic decalcification to other debridement methods, highlighting its safety and thoroughness.

Main Results:

  • Achieved superior valve seating and allowed for the implantation of larger prosthetic valves.
  • Reported a 0% incidence of paravalvular leak or valve failure.
  • Observed a low operative mortality of 1.1% (1/92) and 0% incidence of permanent stroke.

Conclusions:

  • Ultrasonic decalcification is a safe and effective method for remodeling heavily calcified aortic and mitral valve annuli.
  • This technique significantly improves valve seating, reduces complications, and enhances surgical outcomes in challenging cases.
