Percutaneous left atrial appendage closure (LAAO) with Watchman has FDA approval since March 2015, having shown, in the PROTECT-AF and PREVAIL studies, reduced risk of atrial fibrillation driven stroke, by excluding the left atrial appendage form systemic circulation. Both studies used post procedure standardized protocols involving followup at 45 days and 6 months, imaging, and...
At present, percutaneous coronary intervention (PCI) is the most common coronary revascularization strategy. One of its benefits is that patients can be safely discharged when procedures are programed, which helps decompress hospital capacity. However, this strategy has not been validated for acute coronary syndromes; the evidence gathered for non-ST elevation ACS is far from robust,...
For lesions in the common femoral artery, guidelines recommend surgical endarterectomy (TEA) as the gold standard. However, endovascular therapy (EVT) is an alternative option for these lesions. In 2017 the first randomized study comparing TEA vs EVT was carried out, showing that EVT presents clinical benefits, though it does not replace surgical treatment as first...
We all know the benefits of ultravascular ultrasound (IVUS) in the development of percutaneous coronary intervention, such as more accurate vessel measurement, improved stent expansion and apposition, and complication identification. This is why the use of IVUS is a class IIa recommendation in AHA and ESC guidelines. The aim of this retrospective study was to...
The MASTER DAPT study analyzed the results of an abbreviated (mean 34 days) vs. conventional dual antiplatelet therapy (DAPT) in 4579 patients treated with angioplasty and a biodegradable polymer sirolimus-eluting stent. This recent publication on the same study analyzed the evolution within the same strategies of the subgroup of patients with complex angioplasty and compared...
Dual antiaggregation therapy (DAPT) with ASA and P2Y12 during 6 to 12 months is the indicated strategy after DES stenting to reduce ischemic events. However, in patients with elevated risk of bleeding (HBR) guideline and expert recommendations is 1-6 months, since there is plenty of evidence in favor, except for a randomized study, the MASTER...

Percutaneous treatment of coronary lesions affecting bifurcations has increased in recent decades. Coronary angioplasty (percutaneous coronary intervention, PCI) in these cases is associated with an increased rate of adverse events in patients with multivessel disease and left main coronary artery lesions. The SYNTAX score, which is a predictor of total mortality, is used to evaluate...
Drug coated balloons (DCB) emerged as an innovative treatment approximately 10 years ago. Since then, numerous randomized studies have shown their effectiveness and benefit in femoropopliteal territory, and even though the use of paclitaxel coated balloons has been called into question, a retrospective study including 168,553 patients was able to show paclitaxel coated balloons were...
Takotsubo Syndrome (STT) is characterized by acute cardiac failure which can be reversed in many occasions, but is associated with morbidity and mortality at short and long term. It is most frequent among women, especially after menopause. However, gender differences have not been looked into when analyzing the evolution of this cardiomyopathy. This was an...
