Abstract

he severity of mitral regurgitation (MR) with multiple regurgitant jets is often underestimated on standard transthoracic ehocardiography (TTE) examination, since all jets are usually not appreciated. On the other hand, of all Doppler methods only quantitative PW Doppler measurement is applicable in these patients since PISA is not as accurate and vena contracta works well only for single jets.
We present a 57-year-old patient with small and narrow central jet on TTE in whom transesophageal echocardiography (TEE) was performed because of loud apical holosystolic murmur and low effort tolerance in the presence of normal left ventricular function, normal mitral valve and coronary artery anatomy. TEE disclosed two additional significant eccentric jets. Regurgitant volume of 55 ml/beat and ERO 0,35 cm2 was calculated with quantitative PW Doppler method which corresponded to moderate to severe MR.
We stress again the importance of integrative approach in the assessment of MR severity, in which symptoms, physical examination and hemodynamic consequences of MR should not be neglected.
