While drug-eluting stents (DES) have proven to be superior to bare-metal stents (BMS) for coronary arteries, such superiority is unclear as regards vein grafts. Several studies with first-generation DES (DES1) have even reported...
The MiStent device is made of cobalt-chromium, with struts of up to 64 µm thick. It is coated with a completely absorbable polymer that contains a microcrystalline form of sirolimus that embeds directly into the vessel wall. The drug is eluted continuously for up to 9 months. This was a multicenter noninferiority study that randomized patients...
Newer P2Y12 blockers are the front-line treatment and dual antiplatelet therapy is indicated for 1 year after acute coronary syndrome (ACS). Both prasugrel and ticagrelor offer more ischemic benefit than clopidogrel during the initial phase; however, bleeding complications could increase in the long term. The objective of this study was to assess the safety and efficacy...
Courtesy of Dr. Carlos Fava. The presence of chronic total occlusions (CTO) in coronary angiograms varies between 5% and 30%, depending of the different analyzis. Likewise, they have been associated to higher mortality rate and the need for myocardial revascularization surgery. The frequency of CTO PCI is low across the different series (3.8%), though...
Courtesy of Dr. Carlos Fava. The presence of chronic obstructive pulmonary disease (COPD) is a criterion for which patients are ruled out for surgery and proposed as candidates for its current alternative, transcatheter aortic valve replacement (TAVR). A minimalist strategy could benefit this patient group, given the use of conscious sedation instead of general anesthesia. ...
The ICTUS (Invasive Versus Conservative Treatment in Unstable Coronary Syndromes) trial compared early invasive strategy with a selective invasive strategy in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS), with elevated markers such as cardiac troponin T. The absence of long-term benefit of an early invasive strategy at 1 and 5 years had already been reported....
Courtesy of Dr Carlos Fava. The association of primary angioplasty with multivessel lesions is not infrequent and has been analyzed in various studies and meta-analyses. However, the proper course of action remains unclear. According to this study, fractional flow reserve (FFR) could better define the ischemic impact of lesions and help with the identification of...
Courtesy of Dr. Carlos Fava. Provitional ventricular assist devices are increasingly used in high-risk angioplasties, particularly those involving unprotected left main coronary artery (LMCA) with defective ventricular functioning. However, so far its true role has not been well-studied. This study analyzed 127 consecutive patients in the USpella registry from 2008 to 2015. These subjects underwent high-risk...
Courtesy of Dr. Carlos Fava. For type A and B femoropopliteal artery lesions, percutaneous transluminal angioplasty (PTA) with balloon has proven beneficial; however, drug-eluting balloons (DEB) have shown superiority as regards restenosis. Some studies have reported favorable outcomes for DEB in type C and D lesions, but its real benefit is still unclear. This study prospectively...
Courtesy of Dr. Leiva. Bioresorbable scaffolds with drug-eluting stents (bioresorbable vascular scaffolds, BVS) have been added to the list of endovascular treatment options for coronary disease. The ABSORB III trial showed the non-inferiority of this stent type to everolimus-eluting metallic stents as regards target-lesion revascularization (TLR) at one year. However, reports have suggested a higher...
