    Abstract:
    The incidence and severity of ventricular arrhythmias were compared with hemodynamic findings of cardiac catheterization, in 160 patients with mitral and aortic valve disease. All patients underwent right and left heart catheterization, as well as M-mode and 2D-echocardiography, and 24-hour ambulatory electrocardiographic monitoring. Out of 160 patients, 68 had mitral valve disease and 92 had aortic valve disease. In mitral regurgitation the degree and frequency of ventricular arrhythmias showed a positive correlation to the degree of regurgitation (rs = 0.44, rs = 0.56, respectively) and a negative correlation to left ventricular ejection fraction (rs = -0.49, rs = -0.57) and to cardiac index (rs = 0.48, rs = 0.53). In aortic valve disease the incidence and severity of ventricular arrhythmias were not related to the type of valve lesion, to the transvalvular pressure gradient nor to the degree of regurgitation. In aortic stenosis, the degree of arrhythmia showed a negative correlation to left ventricular ejection fraction (rs = 0.55) and a positive correlation to left ventricular endsystolic volume index (rs = 0.40) and to peak systolic left ventricular wall stress (rs = 0.59). In aortic regurgitation the number of ventricular arrhythmias showed a negative correlation to left ventricular ejection fraction (rs = -0.43) and a positive correlation to left ventricular endsystolic volume index (rs = 0.43) and to peak systolic left ventricular wall stress (rs = 0.37). These data demonstrate that the incidence and severity of ventricular arrhythmias, in patients with aortic valve disease and mitral regurgitation, are strongly associated with the impairment of left ventricular function.
