Use of a photo‐realism 3D rendering technique to enhance echocardiographic visualization of the anatomical details during beating‐heart mitral valve repair

The NeoChord procedure is an innovative microinvasive, transventricular, beating‐heart chordal replacement technique for patients with severe degenerative mitral valve regurgitation resulting from prolapsed or flail leaflets. Use of three‐dimensional (3D) transoesophageal echocardiographic imaging is crucial to the physician operator for device navigation during the procedure and to assess the functional results of the repair at the end of the procedure. Photo‐realistic, 3D rendering techniques have been recently developed for medical use. Philips TrueVue (Philips Healthcare, Eindhoven, NL) is a photo‐realism technique that employs the use of a virtual light source that simulates the interaction of light on 3‐dimensional surfaces. Use of photo‐realism techniques, in conjunction with 3D echocardiography, improves the visualization of morphological characteristics of the mitral valve before, during, and after beating‐heart mitral valve repair procedures.     

Impact of direct acting antivirals (DAAs) on cardiovascular events in HCV cohort with pre-diabetes

Background and aimsBeyond type 2 diabetes, even a condition of prediabetes is associated with an increased cardiovascular (CV) risk, and HCV infection coexistence represents an exacerbating factor. CV prognosis improvement in prediabetes represents a challenge, due to the increasing prevalence of this metabolic condition worldwide. Hence, we aimed to prospectively assess how direct acting antivirals (DAAs) could affect major cardiovascular events (MACE) in a prediabetic HCV positive cohort.Methods and resultsIn this prospective multicenter study, we enrolled HCV patients with overt prediabetes. We compared a subgroup of patients treated with DAAs with untreated prediabetic controls. We recorded all CV events occurred during an overall median follow-up of 24 months (IQR 19–34). 770 HCV positive prediabetic patients were enrolled, 398 untreated controls and 372 DAAs treated patients. Overall, the CV events annual incidence was much higher among prediabetic treated patients (1.77 vs. 0.62, p < 0.001), and HCV clearance demonstrated to significantly reduce CV events (RR: 0.411, 95%CI 0.148–1.143; p < 0.001), with an estimated NNT for one additional patient to benefit of 52.1. Moreover, an independent association between a lower rate of CV events and HCV clearance after DAAs was observed (OR 4.67; 95%CI 0.44–53.95; p = 0.016).ConclusionsHCV eradication by DAAs allows a significant reduction of MACEs in the prediabetic population, and therefore represents a primary objective, regardless of the severity of liver disease and CV risk factors.
