Preparazione di liquidi perfluorurati per via elettrochimica
No full textSi riportano i risultati di una serie di ricerche svolte nel campo della elettrofluorurazione di composti organici per la preparazione di liquidi perfluorurati in grado di essere impiegati come "oxygen carriers". Si riporta l'elettrofluorurazione in HF della N-metilmorfolina, N-etilpiperidina, tributileammina e del dibutilsolfur
The anatomy is the plastic image of function: the role of the ventricle-aortic angle in TAVR
No full textThe horizontal aorta of 51° or more, dilated annulus and severe asymmetric calcifications result the three anatomical key features in predicting worse outcome after transfemoral TAVR with the new iterations of self-expandable devices. These findings further validate the ESC guidelines on the importance of anatomical factors in favoring TAVR or surgical aortic valve replacement. Future trials on head to head comparison between valves and on the role of ancillary devices are important to refine final decision making of the heart team on the type of aortic valve replacement and type of valve
Tailwind of transcatheter mitral valve repair pushes forward the treatment of acute mitral regurgitation after myocardial infarction
No full textKey PointsAcute mitral regurgitation after myocardial infarction is associated with high mortality and morbidity.Treatment with the MitraClip is associated with high procedural success and acceptable mortality whether they presented in or out of cardiogenic shock, provided initial hemodynamic stabilization was first achieved before PMVR.This transcatheter technique represents a valid alternative for selected patients and prospective studies are warranted to inform patient selection and periprocedural management in this acute setting
