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...
Courtesy of Dr. Carlos Fava. Moderate/severe paravalvular regurgitation (PVR) after TAVR is present in 10%-14% of all cases, according to different series. The treatment of choice is post-dilation, generally effective in most cases. However, this strategy carries a risk of stroke. The true impact of this conduct is still unclear. This review analyzed 6 studies that included 5007 patients; 889 of...
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. 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...
Courtesy of Dr. Carlos Fava. Nowadays, the number of coronary angioplasties carried out on patients with chronic total occlusion (CTO) is increasing due to many studies showing that it improves ventricular function, reduces symptoms, and improves survival. However, most of these works do not include patients of over 75 years old due to their frailty and...
Courtesy of Dr. Guillermo Migliaro. Drug eluting stents (DES) represented the greatest technological advance in the treatment of instent restenosis from conventional metallic stents (BMS), especially cobalt chromium everolimus eluting stents (CoCr EES), which have shown an excellent profile, and are mostly safer, compared to first generation DES. Indeed, several randomized studies and meta-analyzis have...
Courtesy of Dr. Carlos Fava. Surgical aortic valve replacement (SAVR) continues to be elective, but the presence of post-procedural acute myocardial infarction (AMI) has been associated to bad evolution. Despite the proven benefits of TAVR for high risk patients and the progress shown by patients of intermediate risk, the incidence of post implantation MI has...
Courtesy of Dr. Carlos Fava. One of the questions around drug-eluting stents (DES) is whether the development of biodegradable polymers would derive in better outcomes than the performance of durable polymers as regards the presence of events. In consequence, the COMPARE II trial was carried out with the aim of testing them in “real-world” patients. This...
