As experience increases, transcatheter aortic valve replacement (TAVR) has expanded to different populations and anatomies. This study sought to compare technical and clinical outcomes in patients with bicuspid versus tricuspid aortic stenosis from the Bicuspid AS TAVR Multicenter Registry. Outcomes of 561 patients with bicuspid valves and 4546 patients with tricuspid valves were compared. Propensity score matching was used...
Certain studies have carried out a tomographic follow-up of patients who underwent transcatheter aortic valve replacement (TAVR) and described the frequency of leaflet thrombosis; however, in most cases, it is unclear whether this finding requires some sort of intervention. The difference between this work and those previously published is that this study is not focused on imaging, it...
Courtesy of Dr. Carlos Fava. The balloon aortic valvuloplasty (BAV) was introduced by Dr. Cribier in 1986. However, given its poor results, soon after it fell into disuse. With the introduction of TAVR, it saw a revival as bridge for another intervention, even though it is still resisted in many places. The present study...
Courtesy of the SBHCI. Chronic total occlusions represent around 18% of all coronary lesions. However, they account for just 5% of all interventions, which means that many patients only receive medical treatment. This prospective, open, multicenter study randomized patients with multivessel lesions in whom at least one of these was a chronic total occlusion. Patients...
Courtesy of Dr. Carlos Fava. The presence of chronic obstructive pulmonary disease (COPD) is a criterion for which patients are ruled out for surgery and proposed as candidates for its current alternative, transcatheter aortic valve replacement (TAVR). A minimalist strategy could benefit this patient group, given the use of conscious sedation instead of general anesthesia. ...
Courtesy of Dr. Carlos Fava Few post TAVR scenarios remain to be analyzed. One of them is post TAVR valve thrombosis. This event has been reported in around 0.5% of cases, but its incidence, consequences and adequate treatment remain unclear. The study analyzed 642 patients undergoing TAVR. Patients were followed up with Doppler Echocardiography...

This study seeks to prove the safety and efficacy of rapid left ventricular pacing through a 0.035” guidewire during aortic valvuloplasty and transcatheter aortic valve replacement (TAVR). Right ventricular temporary pacing placed through venous access during aortic valvuloplasty or during TAVR is time-consuming and, above all, associated with cardiac perforation and tamponade. Since...
Courtesy of Dr. Guillermo Migliaro. The Provisional Stenting technique (PS) consists of sequentially placing a stent in the main branch of the bifurcation and, only when faced with a suboptimal outcome (such as < 3 TIMI flow, flow limiting dissection or high residual stenosis), a second stent in the side branch. Several studies have shown...
Courtesy of Dr. Carlos Fava. Aortic valve calcification and mitral annular calcification have the same etiology and are frequently present in high-risk patients undergoing transcatheter aortic valve replacement (TAVR). The implications of mitral annular calcification for patients undergoing TAVR has not been entirely clarified yet. The study examined 782 patients with severe aortic stenosis who underwent...
