Abstract

Two patients with acute tricuspid bacterial endocarditis in which a normal right ventricular Doppler filling pattern was demonstrated early following valvectomy are reported. After surgery, on pulsed Doppler examination, the sample volume positioned at the right atrioventricular level revealed a normal M-shaped filling pattern. A pathologic monophasic pattern was documented a few months later. Our findings suggest that early after surgery the preserved gradient throughout ventricular diastole leads to a passive and active filling similar to normal. Only at a later stage is the grossly dilated right atrium unable to maintain active filling, and the ‘A’ wave disappears despite the fact that sinus rhythm is maintained. Tricuspid valve diastolic motion represents a product of the several factors that determine atrioventricular gradient, but the valve itself appears not to be involved in the generation of a normal filling pattern.
