a large part of this discrepancy can probably be attributed to natural improvements in surgical techniques and post-operative patient management&#44; and changes in population case mix and outcomes in recent years&#46;<a class="elsevierStyleCrossRefs" href="#bib0230"><span class="elsevierStyleSup">12&#44;31</span></a> By contrast&#44; both EuroSCORE II and STS score showed excellent calibration&#46;</p><p id="par0100" class="elsevierStylePara elsevierViewall">Nevertheless&#44; the logistic EuroSCORE I showed good discriminative power&#44; which was not statistically different from EuroSCORE II or STS score&#44; so ultimately no particular score was favored&#46; Barili et al&#46; also found this lack of added value when using ROC curves to compare the two versions of EuroSCORE in general cardiac surgery&#46;<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">18</span></a> In another study by the same authors&#44;

theoretical and methodological concerns have been voiced regarding calibration of EuroSCORE II&#44; particularly regarding the validity of the Hosmer-Lemeshow test for this purpose&#46; Barili et al&#46; set out to answer such concerns in a recent study including more than 12<span class="elsevierStyleHsp" style=""></span>000 patients undergoing cardiac surgery&#46;<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">18</span></a> The authors employed four different methods to assess calibration &#40;including the use of calibration curves&#41; and demonstrated that EuroSCORE II has an optimal calibration performance until 30&#37; actual mortality&#44; beyond which it progressively overestimates mortality&#46; On the basis of these findings&#44; EuroSCORE II could be considered an appropriate tool to assess operative risk in the general octogenarian population&#44; including our study cohort&#46; However&#44; in a truly high-risk population&#44; such lack of calibration can be crucial&#44; particularly when considering transcatheter therapy&#46;</p><p id="par0110" class="elsevierStylePara elsevierViewall">Our findings appear to suggest that EuroSCORE II should be the preferred tool for estimation of operative risk mortality in octogenarians undergoing isolated AVR surgery&#46; The STS score&#44; although equally well calibrated&#44; has the potential disadvantages of being derived from an American cohort and being more cumbersome and time-consuming due to a larger set of variables&#46;</p><p id="par0115" class="elsevierStylePara elsevierViewall">More than a decade after the introduction of TAVI for the treatment of severe AS&#44; should age be a decisive factor in the decision whether to deny AVR surgery&#63; Naturally&#44; age per se&#44; or as a surrogate of an increased prevalence of operative risk factors&#44; is always present in all risk scores&#46; An analysis by Iung et al&#46; showed that low LVEF and greater age were significantly associated with the decision to deny surgery to 72 out of 216 patients with severe AS aged &#8805;75&#46;<a class="elsevierStyleCrossRef" href="#bib0330"><span class="elsevierStyleSup">32</span></a> Neurological dysfunction was the only comorbidity significantly linked with the decision not to operate&#44; which seems to suggest that age itself&#44; rather than associated comorbidities&#44; is used as a true criterion more than a surrogate marker to assess a patient&#39;s pre-operative physiological status&#46; Still&#44; issues related to quality of life in the very old&#44; which are inherently subjective and difficult to evaluate&#44; should also be considered when deciding on the potential benefit of AVR&#46;</p><p id="par0120" class="elsevierStylePara elsevierViewall">Our patient cohort&#44; although limited in size and inevitably suffering the limitations and biases of a single-center analysis&#44; contributes to the growing evidence that isolated AVR surgery can indeed be performed with acceptable results in selected octogenarians&#46; Furthermore&#44; current age boundaries are progressively being challenged&#46; Yerebakan et al&#46; reported 7&#46;6&#37; overall operative mortality in a cohort of 119 nonagenarian patients&#44; of whom 66 underwent isolated AVR&#46;<a class="elsevierStyleCrossRef" href="#bib0335"><span class="elsevierStyleSup">33</span></a></p><p id="par0125" class="elsevierStylePara elsevierViewall">Proper patient selection has a decisive role in achieving good operative results&#46; A number of conditions such as LVEF &#60;30&#37;&#44; severe renal failure&#44; severe lung disease&#44; emergent surgery and simultaneous CABG have been identified as markers of poor outcome&#46; Each of these variables&#44; when added to age as the sole variable contributing to increased operative risk&#44; may advise against AVR&#44; not only because of the expected high operative mortality but also due to the reduced long-term benefit of the intervention&#46;<a class="elsevierStyleCrossRefs" href="#bib0200"><span class="elsevierStyleSup">6&#44;24</span></a></p><p id="par0130" class="elsevierStylePara elsevierViewall">In an increasingly aging population&#44; the number of patients who need a therapeutic intervention will continue to grow&#46; From these results&#44; and given the advent of TAVI and the data from the PARTNER trial&#44; the question arises of what is the best treatment option&#46;<a class="elsevierStyleCrossRefs" href="#bib0210"><span class="elsevierStyleSup">8&#44;34</span></a> The answer can be found by an objective assessment of each case&#44; and for the most difficult and doubtful cases&#44; a multidisciplinary evaluation by the &#8220;heart team&#8221; would be desirable to find the best option for the patient&#46; In this regard&#44; the development of a new&#44; integrated score&#44; perhaps including variables such as frailty&#44; could help to define the best treatment strategy for each individual case&#44; similar to what the SYNTAX II score did for revascularization in coronary artery disease&#46;

Still&#44; issues related to quality of life in the very old&#44; which are inherently subjective and difficult to evaluate&#44; should also be considered when deciding on the potential benefit of AVR&#46;</p><p id="par0120" class="elsevierStylePara elsevierViewall">Our patient cohort&#44;
