Early angiography is not associated with a reduction in mortality compared with a more delayed invasive strategy in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). However, a new meta-analysis published by The Lancet supports the idea that certain high-risk patients would benefit from it. Patients with elevated cardiac biomarkers, a high GRACE score, diabetes, or advanced...
Courtesy of Dr. Carlos Fava. Currently, chronic total occlusions (CTO) are one of the obstacles that coronary angioplasties must overcome, particularly with the development of drug-eluting stents (DES) and new devices and strategies for these challenging lesions. However, there is little information on the safety, efficacy, and real clinical benefit of implanting stents of over 60 mm (known as full metal jackets, FMJ)....
The prevalence of pre-procedural kidney failure in patients undergoing transcatheter aortic valve replacement (TAVR) can be as high as 50 – 60% (stage 3 kidney failure or worse); it has been strongly associated with acute kidney deterioration and, ultimately, an increase of post TAVR mortality. A recent meta-analyzis of several small studies carried out in a single...
There are plenty of clinical studies assessing the use of angioplasty for en la peripheral artery disease with restenosis rates as high as 40% and 60% at 6 and 12 months. Drug coated balloons have significantly raised primary patency, but they have mostly been tested in short lesions with mild calcification and no total occlusions. This...
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...
Readmissions at 6 months in patients with critical ischemia in the lower limbs occur in about 50% of all cases and most of them are unplanned. This truly alarming number is cause for further concern when taking into account that only part of these readmissions are related to vascular problems. Many are caused by comorbidities...
Courtesy of Dr. Carlos Fava. It has been proved that in a setting of acute myocardial infarction with multivessel lesions, only the culprit vessel must be treated (if there is no hemodynamic compromise) at first, and other severe lesions are to be treated during a second session. However, proper conduct in cases with presence of chronic...
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...
Courtesy of Dr. Carlos Fava. It is known that patients with low gradient aortic stenosis show poor evolution with medical treatment and, in addition, present high mortality rate with surgery. As regards TAVR, a far simpler procedure compared to surgery, there is contradicting evidence; while some studies claim it holds comparable risks, others have found...
