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. ...
There is an important group of patients presenting low flow, low-gradient severe aortic stenosis (defined as mean gradient <40 mmHg). This is why we do dobutamine stress echocardiogram (DSE), to confirm whether we are dealing with truly severe aortic stenosis. However, it might not be well tolerated and a CT angiography will be done to...
Transcatheter aortic valve replacement (TAVR) has evolved since it was first implemented, and it is now also used to treat low risk patients. One of the questions this has raised is whether patient life expectancy is higher than prosthesis life expectancy. The growing population in need for valve replacement also poses the question of how...
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...
We are well aware of the benefits of TAVR in different scenarios, but the need for permanent pacemaker implantation (PPI) in self-expandable valves is between 15% and 30% according to different randomized and non-randomized studies. This is why the higher implantation strategy or cusp overlap (COT) was developed and, though it has been shown to...
Transcatheter aortic valve replacement (TAVR) has been proving its benefit in different scenarios for two decades now. However, in the field of self-expanding valves, one challenge has always been its high rate of pacemaker implantation compared with balloon-expandable devices and valvular replacement surgery. For this reason, the high implantation or Cusp Overlapping strategy was developed....
Conventional radial access (CRA) has a proven great benefit as it lowers the rates for bleeding and complications. Also, this access is more comfortable for the patient. Currently, distant radial access (DRA) is being used in some patients. However, its benefit remains unclear, as few studies have analyzed it. In this sense, this meta-analysis that...
Coronary artery disease (CAD) coexists with aortic stenosis in about half the patients who suffer the latter. These patients receiving antiplatelet therapy are at a higher risk of periprocedural bleeding—one of the most frequent complications in patients who undergo transcatheter aortic valve replacement (TAVR). One way of limiting the risk for bleeding is choosing the...
The rise of chronic total occlusions (CTO) percutaneous coronary interventions (PCI) goes hand in hand with technological development, through still posing a great challenge, one not exactly exempt from complications. An important criterion to successful CTO PCI is length: ≥20 mm lesions lower the odds, according to J-CTO Score. However, increasing operator experience and the...
