Transcatheter arterial chemoembolization for hepatocellular carcinoma in cirrhosis;survival rate and prognostic factors
2010
Background: The role of prognostic variables in the treatment of hepatocellular carcinoma (HCC) by transarterial chemoembolisation (TACE) is controversial. Aims: To evaluate the survival of patients with HCC on cirrhosis treated with TACE and to analyse the prognostic factors affecting survival. Methods: From 1996 to 2006, 580 consecutive patients with HCC in cirrhosis were observed. Of these 194 patients underwent TACE. The primary end-point was survival. Independent predictors of survival were identified using the Cox model. Results: The cumulative 1-year, 3-year, and 5-year survival rates were 96%, 60%, and 41%, respectively. The multivariate analysis showed significant reduction of surv…
3D Printing and Computational Modeling for the Evaluation of LVOT obstruction in Transcatheter Mitral Valve Replacement
2022
Transcatheter mitral valve replacement (TMVR) is an emerging alternative treatment for those patients not qualified for surgery. However, TMVR can determine an obstruction of the left ventricular outflow tract (namely, neo-LVOT) induced by the transcatheter heart valve (THV) displacing the native mitral valve leaflet towards the myocardial wall. This condition can lead to haemodynamic impairment and ultimately patient death. We sought to predict the neo-LVOT obstruction by first developing patient-specific simulations of the THV deployment and then comparing predictions with post-TMVR diagnostic images and 3D printed human models. Using pre-TMVR computed-tomography (CT) imaging, patient-spe…
