Implication

Diminished AO/AC ratio may support phonocardiographic detection of ball variance; leaves open need for prospective validation before clinical adoption.

Structured PICO

Can phonocardiography accurately diagnose aortic ball variance in patients with Starr-Edwards aortic prostheses?

P
Population
43 patients with Model 1000 series Starr-Edwards aortic valve prostheses, including 12 with operatively confirmed ball variance and 31 controls.
I
Intervention
Phonocardiography
C
Comparator
Controls without ball variance
O
Outcome
Detection of ball variance based on aortic opening sound (AO) to aortic closure sound (AC) ratiosurrogate

Phonocardiography provides reliable objective evidence of ball variance in patients with Starr-Edwards aortic prostheses by demonstrating a decreased AO/AC ratio.
