Conclusioni. Nel trattamento percutaneo <strong>di</strong> occlusione <strong>di</strong> DIA, evidenze cliniche<br />
e strumentali hanno mostrato elevate e sovrapponibili percentuali <strong>di</strong> successo<br />
acuto e lungo termine, sia con l’impiego <strong>di</strong> TEE sia <strong>di</strong> ICE. In pazienti non<br />
selezionati, la meto<strong>di</strong>ca ICE si è <strong>di</strong>mostrata in grado <strong>di</strong> ridurre significativamente<br />
i tempi <strong>di</strong> scopia e <strong>di</strong> procedura, evitando inoltre la sedazione profonda del<br />
paziente, necessaria con l’impiego della TEE.<br />

Aims. The continuity equation represents the gold standard for the evaluation of<br />
aortic valve area in patients with aortic stenosis, but it is subject to error, time<br />
consuming, and can be technically deman<strong>di</strong>ng. Recently, a new<br />
echocar<strong>di</strong>ographic non-flow corrected index has been introduced and<br />
demonstrated an excellent accuracy in quantifying the effective orifice area in<br />
native aortic valves and bioprostheses. This new index, the ejection fractionvelocity<br />
ratio, is obtained by <strong>di</strong>vi<strong>di</strong>ng the percent left ventricular ejection fraction<br />
at the maximum aortic gra<strong>di</strong>ent (EFVR=EF/4V 2 ). The aim of our study was to<br />
assess the utility of this echocar<strong>di</strong>ographic index to quantify the effective orifice<br />
area in patients with aortic bioprosthesis and left ventricular dysfunction.<br />
Methods. We stu<strong>di</strong>ed 70 patients (25 women and 45 men, mean age of 71.4±9<br />
years) with aortic bioprosthesis and left ventricular dysfunction (EF ≤49%), and<br />
we evaluated the effective orifice area by both continuity equation and ejection<br />
fraction-velocity ratio.<br />
Results. We found a significant linear correlation between the continuity equation<br />
and the ejection fraction-velocity ratio (r=0.80; p
