Enlightening the Association between Bicuspid Aortic Valve and Aortopathy
Bicuspid aortic valve (BAV) patients have an increased incidence of developing aortic dilation. Despite its importance, the pathogenesis of aortopathy in BAV is still largely undetermined. Nowadays, intense focus falls both on BAV morphology and progression of valvular dysfunction and on the development of aortic dilation. However, less is known about the relationship between aortic valve morphology and aortic dilation. A better understanding of the molecular pathways involved in the homeostasis of the aortic wall, including the extracellular matrix, the plasticity of the vascular smooth cells, TGFβ signaling, and epigenetic dysregulation, is key to enlighten the mechanisms underpinning BAV-aortopathy development and progression. To date, there are two main theories on this subject, i.e., the genetic and the hemodynamic theory, with an ongoing debate over the pathogenesis of BAV-aortopathy. Furthermore, the lack of early detection biomarkers leads to challenges in the management of patients affected by BAV-aortopathy. Here, we critically review the current knowledge on the driving mechanisms of BAV-aortopathy together with the current clinical management and lack of available biomarkers allowing for early detection and better treatment optimization

Native T1 mapping to detect extent of acute and chronic myocardial infarction:comparison with late gadolinium enhancement technique
Comparison of myocardial reperfusion between intracoronary versus intravenous cangrelor administration in patients undergoing primary percutaneous coronary intervention
Background: Myocardial reperfusion is the main target of treatment in patients with ST-segment elevation myocardial infarction (STEMI). The intracoronary administration of cangrelor bolus could favor a higher local drug concentration, favoring an earlier thrombotic resolution and a reduced distal micro-embolization. Methods: Seventy-one patients undergoing primary percutaneous coronary intervention (PCI) for STEMI: 37 treated with intracoronary and 34 with intravenous bolus administration of cangrelor. The primary endpoint was ST-elevation reduction (STR) ≥ 50% after 30 min from the end of the PCI. Other explorative reperfusion indices investigated were: STR ≥ 50% at 24 hours, STR ≥ 70% at 30 min, Thrombolysis In Myocardial Infarction frame count and the QT dispersion (QTd). Moreover, acute and subacute stent thrombosis, bleeding events and 30-day mortality have been evaluated. Results: More frequent STR ≥ 50% was observed in the intravenous cangrelor bolus group as compared to the intracoronary administration at 30 min (71.9% vs. 45.5%; p = 0.033), the difference was maintained 24 hours after PCI (87.1% vs. 63.6%; p = 0.030). STR ≥ 70% at 30 min was statistically more frequent in the intravenous bolus administration cohort (66.7% vs. 28.6% p = 0.02). At multivariable analysis, intravenous cangrelor administration was significantly related to STR ≥ 50% (odds ratio: 3.586; 95% confidence interval: 1.134–11.335; p = 0.030). The incidence of Bleeding Academic Research Consortium 3–5 bleedings was 15.5% and mortality was 4.2% without any significant difference between the two groups. Conclusions: In conclusion the results of the study do not show any advantages in the administration of intracoronary bolus of cangrelor in patients affected by STEMI and treated with primary PCI
