Thromboembolic pulmonary hypertension is caused by pulmonary artery stenosis caused by organized thrombi. The only treatment potentially healing for this disease is surgical thrombectomy. However, patients with lesions in very peripheral branches or high surgical risk patients with comorbidities might benefit from a plan B, such as balloon pulmonary angioplasty. The percentage of patients with chronic...
The DAPT study concluded that continued thienopyridine plus aspirin beyond a year after coronary angioplasty is associated with a decrease in the rate of stent thrombosis and major cardiovascular events. In contrast, there is a significant increase in moderate to severe bleeding when compared with continued aspirin alone. Based on the outcomes of this and...

This has been already analyzed in the context of TAVR, but not in MitraClip procedures. The present study analyzed 232 patients receiving the MitraClip. 76 of these procedures were done under general anesthesia (32.7%) and...
Transcatheter aortic valve replacement (TAVR) was developed as a strategy to treat non-surgical aortic stenosis, and was later expanded to elderly patients at intermediate risk, because of increased operator experience (overcoming the learning curve) and improved devices. The present study presents the one year outcomes of the SOURCE 3 trial, the multicenter European registry of the...
Much has been done since studies on conventional balloon angioplasty for BMS instent restenosis showed over 40% new revascularization. Drug eluting stents, aimed at improving this problem, have never achieved 0% restenosis, which is why technologies such as paclitaxel coated balloons have been developed, with reasonable efficacy (8% to 10% reinterventions rate for BMS restenosis and 17% to 23%...
A recent presentation at London Valves took a closer look at the REPRISE III trial as regards two points that generated much discussion, such as need for a pacemaker and paravalvular leak. REPRISE III had previously demonstrated that the Lotus is noninferior to first-generation CoreValve and Evolut R in terms of safety. Additionally, it proved to be superior...

A small annulus in patients with Severe Aortic Stenosis is a real challenge, since it is associated with post-surgical prosthesis patient mismatch (PPM), which negatively affects prosthesis duration and evolution. TAVR has become a good alternative strategy, with better hemodynamic profile and lower PPM incidence in this group. The present study included 246...
Paravalvular leak is complication derived from incomplete sealing between the implanted prosthesis and the native annulus, which occurs in 5% of all patients who undergo mitral valve replacement and 10% of those who undergo transcatheter aortic valve replacement. This is the most frequent non-structural valve dysfunction. While mild leaks can be asymptomatic, moderate to severe...
Myocardial revascularization surgery (CABG) is the most frequent of all cardiovascular surgeries and is still the gold standard to treat multivessel disease. Between 6 and 8% of these patients present concomitant carotid stenosis and it is associated with increased peri and post procedural stroke rates during and after surgery. To prevent carotid stenosis, either PCI or endarterectomy...
Courtesy of Dr. Carlos Fava. The incidence of peripheral vascular disease is clearly increasing, progressing towards critical ischemic claudication and amputation. Angioplasty is currently the treatment of choice for these pathologies. Several times, an implanted stent ends up cracking due to extensive calcification, increasing the rate of restenosis and worsening critical ischemia. Technological development on drug-eluting...
