Integrating volumes into myocardial work: the prognostic role of non-invasive pressure-strain-volume analysis in transcatheter aortic valve implantation.
The accurate echocardiographic assessment of the left ventricular (LV) contractile state remains challenging in aortic stenosis, as ejection fraction and even global longitudinal strain are markedly load-dependent. The novel pressure-strain loop-derived myocardial work were developed to overcome this limitation; howeve...
