Confronto Hard: La deformazione miocardica, il twist, il rocking e il rock and roll, sono solo musica? Pro: G. Tonti Contro: D. Mele Napoli 2011
Ejection fraction: a measure of desperation? Manisty CH, Francis DP. Heart 2008; 94:400-401. “Nowadays, EF is surely only justified as a sole index of cardiac function in situations of desperation when there are no available quantities calibrated in physical units.” “We hope that one day we will no more likely to classify patients with heart failure by EF than we classify patients with cancer by hemoglobin level.” Napoli 2011

Effects of global longitudinal strain and total scar burden on response to CRT in patients with ischaemic dilated cardiomyopathy D’Andrea A et al. Eur J Heart F 2009; 11: 58-67 Average Global longitudinal strain (GLS) correlates closely with MRI total scar burden (r=0.64, P<0.001). GLS and radial intraventricular dyssynchrony were powerful independent determinants of response to CRT. Napoli 2011

Acute Cardiac Functional and Morphological Changes After Anthracycline Infusions in Children Ganame et al, Am J Cardiol 2007;99:974 –977 Individual peak radial systolic ε before and after anthracyclines (ANT). A in peak systolic ε was noted in all patients after the 1st dose of ANT; in some, progressive was seen after the 2nd and 3rd doses. Ten patients showed values < normal limits (50%) after the 3rd dose. Gray area, normal values 1 SD. Napoli 2011

THE (current) FUTURE Napoli 2011
4D Longitudinal Strain Napoli 2010
4D Circumferential Strain Napoli 2010
4D Area Strain Area strain shows % of change of an area from a mid-myocardial layer. It reflects a combination of longitudinal and circumferential strain. Napoli 2010
4D Radial Strain (VolC) 4D Radial Strain VolC is estimated from the area strain using an assumption of volume conservation. The parameter is therefore called “Radial Strain (VolC)”. Napoli 2010

NAPOLI CI CREDE Napoli 2011
DEFORMATION IMAGING • Non c’è tecnica senza limiti, che vanno superati con un atteggiamento non distruttivo ma costruttivo. • I limiti vanno usati per capire come applicare al meglio una tecnica, non per distruggerla. • Occorre andare incontro al futuro, per evitare che il futuro ci colga di sorpresa.
