Using the new devices, the new guidelines and with more experience operators, these procedures are successful in 10% to 30% of cases. More often than not these patients are not treated...
The NIPPON trial (Nobori Dual Antiplatelet Therapy as Appropriate Duration) was a randomized study comparing a short dual antiplatelet therapy scheme (6 months) vs. a prolonged scheme (18 months) in patients receiving the Nobori drug eluting stent (Terumo, Tokyo, Japan) with a biodegradable abluminal polymer. It included 3,773 patients with chronic stable angina or acute coronary...
The association between glycemic control after coronary angioplasty and outcomes of the latter is controversial in many studies. We have come to think that the risk lies in suffering from diabetes, as if it was an unmodifiable factor. We have also come to believe that glycemic control can impact microvascular complications while it cannot do...
There is little information comparing contemporary drug eluting stents (DES) against bare metal stents (BMS), for PCI in saphenous vein grafts in patients receiving (CABG). This study aimed to assess clinical outcomes after PCI in saphenous vein grafts in patients receiving BMS, first generation DES, and new generation DES between 2006 and 2013. The study...
Courtesy of Dr. Agustín Vecchia. The advent of resorbable vascular scaffolds (BVS) generated high expectations among interventionists because of its potential advantages over bare metal stents. However, when comparing BVS against the Xience stent, we observed an increased rate of events associated to the first device, to their detriment. Among the reasons behind this poor...
Courtesy of Dr. Carlos Fava. The prevalence of cardiogenic shock in acute myocardial infarction (MI) is 7%-10%, and it is associated with high mortality rates. Unfortunately, 0.7% of these cases are a consequence of unprotected left main coronary artery (ULMCA) as MI-culprit lesion. Its evolution is generally disastrous. Ventricular assist device support and its implementation time may...
Courtesy of Dr. Agustín Vecchia. In general, guidelines recommend a number of procedures a year for operators to maintain a reasonably safe level of proficiency. Even though this number is arbitrary and operators’ aptitude varies considerable, more than one publication has found an inverse correlation between procedure volume and outcomes. This study incorporated 10,496 operators...
Courtesy of Dr. Carlos Fava. Nowadays, chronic total occlusions (CTO) due to in-stent restenosis (ISR) represent 5%-25% of all coronary angioplasties. These lesions pose a new and true challenge, since CTOs are often associated with stent-related problems (fractures, lack of expansion, overlapping, deformation), extreme tortuosity, severe calcification, tandem lesions after CTO, and aorto-ostial lesions, with little...
Courtesy of Dr. Gustavo Leiva. Coronary Artery Bypass Graft (CABG) has traditionally been the procedure of choice in patients with left main coronary artery disease. However, the use of percutaneous techniques in this kind of lesions has been on the rise, partly due to recent research showing similar outcomes with both procedures. Unprotected left main...
The aim of this study was to compare bivalirudin against heparin in patients with ST elevation acute myocardial infarction undergoing transradial primary PCI. Both bivalirudin and the transradial access are strategies aimed at reducing bleeding complications in patients undergoing acute MI. However, the benefit of their combined use is not year clear. Even though...
