Forty patients having aortic valve replacement were evaluated
preoperatively for ventricular arrhythmia and left ventricular ejection
fraction. Arrhythmias were classified as complex or simple using the Lown
criteria on the 24-hour ambulatory electrocardiogram; ejection fractions
were determined by radionuclide gated blood pool analysis and contrast
angiography. The ejection fractions determined by radionuclide angiography
were 59.1 +/- 13.1% for 26 patients with simple or no ventricular
arrhythmias, and 43.9 +/- 20.3% for 14 patients with complex ventricular
arrhythmias (p less than 0.01). Ejection fractions determined by
angiography, available for 31 patients, were also lower in patients with
complex ventricular arrhythmias (61.1 +/- 16.3% versus 51.4 +/- 13.4%; p
less than 0.05). Seven of 9 patients showing conduction abnormalities on
the electrocardiogram had complex ventricular arrhythmias. Eight of 20
patients with aortic stenosis had complex ventricular arrhythmias, while 2
of 13 patients with aortic insufficiency had such arrhythmias. It is
concluded that decreased left ventricular ejection fraction,
intraventricular conduction abnormalities, and aortic stenosis are
associated with an increased frequency of complex ventricular arrhythmias
in patients with aortic valve disease.
