Angiography-derived fractional flow reserve (FFR) demonstrated substantial usefulness, especially in patients with three-vessel lesions. The functional SYNTAX score derived from angiography has the potential to redefine prognosis and treatment strategies compared with the classic anatomical SYNTAX score. This study sought to investigate the applicability of this method in patients with multivessel lesions included in the...
Both studies followed beyond 5 years patients with severe aortic stenosis who had undergone transcatheter aortic valve replacement (TAVR). Findings included low rates of significant valve degeneration and failure, in both cases. While data on the long-term degeneration of transcatheter-implanted valves are scarce, follow-up from the NOTION trial of low-risk patients and from the UK TAVI...
For the first time, this long term observational study on a large cohort of contemporary patients with aortic stenosis (AS), has shown syncope is an underestimated threat, associated with worse prognosis after surgical aortic valve replacement (SAVR). It is interesting to note that other symptoms or early signs of AS that will normally indicate SAVR...
1- The CULPRIT-SHOCK Study Is Finally Published in NEJM and It Is Bound to Change Guidelines During SOLACI’s coverage of the TCT 2017 Congress in Denver, Colorado, we already mentioned some of the outcomes of this study that has arrived to revolutionize clinical practice, given the differences between its results and those of the classic...
In this large international multicenter population, computed-tomography (CT)-derived fractional flow reserve (FFR) modified treatment recommendation in two-thirds of subjects compared with CT angiography alone, and it was associated with less negative invasive angiographies. It also predicted revascularization and identified low-risk patients. A non-invasive means to know the anatomy and function of patients with stable chronic...
Going beyond the culprit artery during angioplasty was associated with lower mortality, although this was a cohort study that should be confirmed through randomized trials. According to this new observational study, patients experiencing non-ST-segment elevation myocardial infarction with multivessel disease seem to benefit from complete revascularization during initial angioplasty. This study, published online before...
This systematic analysis measured intracoronary pressure in different phases of the cardiac cycle and flow velocity in patients with severe aortic stenosis and coronary artery disease, who were scheduled for transcatheter aortic valve replacement (TAVR). The aim was to determine the impact of aortic stenosis on: 1) flow, at different phases; 2) hyperemic coronary flow;...
Taking into account a simple 12-lead electrocardiography performed immediately after transcatheter aortic valve implantation (TAVI), removing the temporary pacemaker immediately is safe in patients without right bundle branch block who are in sinus rhythm with PR interval <240 ms and QRS interval <150 ms. In cases of atrial fibrillation, a QRS interval <140 ms also reassures the decision...
Programmed exercises are recommended as initial management strategy for patients with peripheral artery disease (PAD). Most exercise programs include supervised treadmill walking twice or three times a week in a strategic facility (such as a gym). PAD patients often give up on these programs seeing as they might find it difficult to keep to a...
All over the world, functional lesion measurement remains underutilized due to the need for a hyperemic stimulus (which may be avoided with instantaneous wave-free ratio [iFR]) and, above all, the invasiveness of guidewire placement (crossing the intended lesion) for the measurement. These guidewires have improved a lot, but they still lack the navigating capacity of...
