Furthermore, it provokes obstructive lesions due to wall fibrosis. Generally, patients with this background are not eligible for surgery and receive angioplasty, a seemingly great alternative. However, there is no clear information on outcomes yet. This...
Courtesy of Dr. Carlos Fava The EVEREST II trial showed the MitraClip had similar mortality rate to that of surgery but, even though residual mitral valve regurgitation (MR) is associated to a strong negative impact, little is known about post MitraClip increased transvalvular gradient and its implication. 268 patients undergoing MC implantation were analyzed....
Current surgical and medical treatment options for severe tricuspid regurgitation are extremely limited. However, this historically forgotten valve seems to have the option of transcatheter repair, nowadays. This observational study assessed the safety and feasibility of the MitraClip system for patients with severe chronic tricuspid regurgitation. All patients presented severe tricuspid regurgitation and...
Courtesy of Dr. Javier Castro. Certain coronary lesions have been historically discouraged for endovascular treatment. Among these can be found left main coronary artery lesions, multivessel disease, and proximal anterior descending artery lesions. As a matter of fact, the latter is actually considered separately as a criterion for choosing the revascularization method. Endovascular treatment of...
Courtesy of Dr. Agustín Vecchia. In the last few years, new percutaneous treatment options for mitral regurgitation have emerged. Transcatheter mitral annuloplasty with various devices is a relatively simple procedure that could compress the origin of circumflex artery branches due to the different orientation of mitral corners and the coronary sinus. The following work by Park...
Courtesy of Dr. Carlos Fava. Atrial fibrillation (AF) and fast heart rate (>70 lpm) have been shown to increase the risk of mitral valve repair surgery. The MitraClip has shown benefits in high risk patients, but its relation to abnormal heart rhythm has not yet been established. 760 patients were analyzed; 315 (52.4%) presented...
Courtesy of Dr. Carlos Fava. The transradial approach has been advanced in time, and is being increasingly used in more and more complex angioplasty procedures with the same benefit, compared to the classical femoral approach. As a result, in many high volume centers, this reality has demoted the femoral approach to a few particular procedures....
For TAVR eligible patients (transcatheter aortic valve replacement) with femoral access counterindication, a new access site, extra thoracic yet percutaneous, may offer an alternative. This consists of reaching the abdominal aorta through the vena cava. With this technique the operator enters the abdominal aorta through the vena cava by electrifying a guidewire, advancing a...
Courtesy of Dr. Carlos Fava. Transfemoral access is the first choice for transcatheter aortic valve replacement (TAVR). However, this approach is not feasible for a progressively larger number of patients, which establishes the need to search for alternative accesses. Between 2009 and 2014, this study enrolled 174 patients who underwent TAVR and were unsuitable for transfemoral...
Courtesy of Dr. Carlos Fava. Left main coronary artery disease (LMD), has historically been treated with myocardial revascularization surgery (CABG), but for some years now, and with the development of new drug eluting stents (DES), percutaneous coronary intervention (PCI) has been gathering support in this challenging territory. The study analyzed the SYNTAX and PRECOMBAT...
