Calcified coronary plaque (CCP) is a challenge for interventional cardiology. Stent underexpansion (SU) commonly associated with CCP could predispose to stent thrombosis or restenosis. Currently, SU in severe CCP can be treated by rotational atherectomy, orbital atherectomy, balloon cutting/scoring, non-compliant high-pressure balloons, or intravascular lithotripsy (IVL). The aim of this meta-analysis was to determine the...
Patients presenting aortic stenosis with cardiogenic shock are at extreme risk, with 70% mortality until the aortic obstruction is resolved, and taking into account they make poor transplant candidates. Safety and efficacy of TAVR in patients with cardiogenic shock remains unclear. The aim of this study was to assess events in patients undergoing TAVR with...
Benefits of abbreviated antiaggregant treatment in high bleeding risk patients. Dual antiplatelet therapy (DAPT), established by different guidelines, reduces the risk of ischemic events at the expense of increased bleeding. This habitual APT strategy cannot be applied to patients at high risk of bleeding, which is why this populations are treated with shorter DAPT schemes...
Predictors of post PCI angina Among the complications of ischemic cardiomyopathy stenting, those called chronic, with significant functional and mental compromise, might affect patient quality of life. This can be observed in different scenarios, such as instent restenosis and post PCI angina. This kind of complications is associated with anxiety and depression at long term. ...
Coronary artery obstruction (CAO) after TAVR is rare, but it entails extremely high mortality (50% or more), especially after valve-in-valve (V-in-V) or when the coronary ostia are is too close to the valve annulus. This is why the BASILICA technique was developed (Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Artery Obstruction)....
Transcatheter aortic valve replacement has shown important benefits but one of its biggest challenges is showing its safety and efficacy at followup in low risk patients. At present we have 2-year data from the Evolute Low Risk, but the we lack information at longer followup. The study looked at 3-year followup of the Evolute Low...
Endovascular recanalization of femoropopliteal occlusions continues to be one of the initial therapeutic strategies to treat this pathology. The anterograde approach via the common femoral is the most frequently used. However, it is not always viable, especially in long occlusions with severe calcification or when the femoral artery cannot be reached. In these cases, the...
We are aware of sex related differences when it comes to comorbidities, physiopathology and disease evolution in patients with tricuspid regurgitation (TR). TR is more prevalent among women, whereas among men, coronary artery disease is more prevalent, with worse left ventricular ejection fraction and 10-year survival rate. Transcatheter tricuspid valve intervention (TTVIs) has surged as...
Sex-related MINOCA and MIOCA differences. Several international guidelines recommend invasive treatment after diagnosing an acute coronary syndrome (ACS). The first studies that described acute myocardial infarction (AMI) without obstructive epicardial coronary disease reported a 10% incidence rate. Based on this significant prevalence, it was recommended that this diagnosis be classified as MINOCA for patients who...
The incidence of in-stent restenosis (ISR) requiring repeat revascularization ranges between 5% and 10% of PCI patients receiving new generation drug eluting stents (DES). This is why the current European guidelines on myocardial revascularization recommend treating ISR with drug coated balloons (DCB) with class I recommendation, level of evidence A. DCB are mostly coated with...
