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. 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...

Between the years 2000 and 2015, the authors of this article searched for reports on spontaneous coronary artery dissection (SCAD) in pregnant or immediate post-partum women aiming at defining the clinical characteristics of this pathology and offering management recommendations. Information on 120 women was analyzed; 116 were between 22...
Courtesy of Dr. Agustín Vecchia. In the last few years, new percutaneous treatment options for mitral regurgitation have emerged. Transcatheter mitral annuloplasty with various devices is a relatively simple procedure that could compress the origin of circumflex artery branches due to the different orientation of mitral corners and the coronary sinus. The following work by Park...
Original Title: Revascularization in Patients with Multivessel Coronary Artery Disease and Severe Left Ventricular Systolic Dysfunction: Everolimus Eluting Stents vs Coronary Artery Bypass Graft Surgery Reference: Bangalore et al. Circulation. 2016 May 5. Epub ahead of print. Courtesy of Dr. Guillermo Migliaro. Guidelines recommend coronary artery bypass graft surgery (CABG) over percutaneous coronary...
The Internal Mammary Artery (IMA) is the preferred conduit for bypassing the left anterior descending artery (LAD) in patients undergoing coronary artery bypass grafting. There is no systematic evaluation of the frequency and predictors of IMA failure or long-term outcomes. The PREVENT IV included 1539 patients receiving IMA-LAD revascularization with 12 and 18 month...
This study included 329 consecutive patients derived to coronary angiography based on myocardial perfusion tests or PET scan (positron emission tomography). The extension and severity of heart disease was assessed by angiography, and coronary flow reserve (CFR) was measured non-invasively by PET. After adjusting risk factors, ejection fraction, revascularization, etc, both the severity of angiographic...
The current recommendation for dual anti-aggregation post-DES implantation is 12 months. However, the ideal length for specific types of stents is unclear. This study aimed to evaluate the clinical non-inferiority at 3 months versus 12 months of dual anti-platelet therapy in patients undergoing coronary angioplasty with zotarolimus-eluting stents. The study randomized 1:1 to 3 months...
The PARIS registry was a prospective observational study in 5018 patients undergoing coronary angioplasty with stent implantation in 15 centers. Three categories were prespecified in the discontinuation of dual antiplatelet therapy: 1) discontinuation for medical guidance, 2) transient discontinuation for less than 15 days for surgery and 3) permanent abandonment of it by non-adherence or...
The trial included 1,900 patients followed for at least 2 years, (mean 3.8 years), randomized 1:1 to pharmacological angioplasty stents, (sirolimus or paclitaxel at surgeon discretion), or CABG. We excluded acute coronary syndromes and left coronary trunk injury. The primary endpoint was death, myocardial infarction or stroke and the secondary main was the sum of...
