    Abstract:
    We assessed the incremental effect of cardiac catheterization upon the management of 93 adult patients with aortic and/or mitral valve disease, referred for surgical consideration. There were 52 patients with aortic valve disease, 29 with mitral valve disease and 12 with aortic and mitral valve disease. Prior to cardiac catheterization, a detailed unblinded ultrasound assessment of each valve was made utilizing 2D and Doppler ultrasound. Based upon the ultrasound result and the clinical assessment, the patient's cardiologist recorded a grading of valve severity and a management decision for each valve. Following catheterization and coronary angiography, the cardiologist repeated the gradings of valve severity and recorded a final management decision. After catheterization, management changed in nine patients and was unchanged in 84. Reasons for management change included differences between echocardiographic and catheterization assessment of valvular regurgitation (three patients), information on coronary anatomy (two patients), minor differences in assessed aortic valve area (one patient) and left ventricular function (one patient), and confirmation of ultrasound findings where clinical and ultrasound findings had been conflicting before catheterization (two patients). Both mitral and aortic valve disease were present in the three patients in whom management changed as a result of significant differences between echocardiography and catheterization assessment of valvular regurgitation. Management was unchanged in the 16 patients with isolated mitral stenosis. In this study, a combination of clinical and noninvasive assessment including Doppler echocardiography, resulted in a reliable evaluation of valvular disease in a large majority of patients.(ABSTRACT TRUNCATED AT 250 WORDS)
