Courtesy of Dr. Carlos Fava. We are well aware of transcatheter aortic valve replacement’s (TAVR) effect in high-risk or inoperable patients at 5 years, even more after the PARTNER 1 trial. Yet, the outcomes of another relevant randomized study remained pending: el CoreValve US Pivotal High-Risk Trial. The CoreValve US Pivotal High-Risk Trial looked at the…
Surprises in the Physiopathology of Critical Ischemia
Luminal thrombotic occlusions associated with non-significant atherosclerosis are commonly observed in patients with critical lower limb ischemia, which suggests the possibility of thromboembolic disease as a great contributor to ischemia. This was particularly verifiable in infrapopliteal vessels, thus showing a possible mechanism of progression from peripheral vascular disease to critical ischemia, as well as a…
Differences in Stroke between TAVR and SAVR in Intermediate Risk Patients
Transcatheter aortic valve replacement (TAVR) is more and more frequent in lower risk populations that had previously been treated with surgical valve replacement (SAVR). A small difference in neurological events could have significant consequences when it comes to deciding a course of action. This study is a sub-analysis of the randomized study SURTAVI (Surgical Replacement…
TAVR in Low-Risk Patients with “Zero” Mortality and “Zero” Stroke
Transcatheter aortic valve replacement (TAVR) is now the standard of care for patients with symptomatic severe aortic stenosis who are at extreme, high, or intermediate risk for surgery. This multicenter, prospective study (Feasibility of Transcatheter Aortic Valve Replacement in Low-Risk Patients With Symptomatic, Severe Aortic Stenosis) included low-risk patients and was approved by the United…
How to predict post TAVR quality of life in “real world” patients
Despite the benefit for most patients, a small number of patients still show poor outcomes after transcatheter aortic valve implantation (TAVR). This work was able to recalibrate a previously developed risk model to predict post TAVR quality of life and provide us with a potential tool to properly estimate the chances of good recovery, or…
What Should We Use for the Functional Assessment of Coronary Lesions in Severe Aortic Stenosis?
This systematic analysis measured intracoronary pressure in different phases of the cardiac cycle and flow velocity in patients with severe aortic stenosis and coronary artery disease, who were scheduled for transcatheter aortic valve replacement (TAVR). The aim was to determine the impact of aortic stenosis on: 1) flow, at different phases; 2) hyperemic coronary flow;…
Galileo: Rivaroxaban After TAVR Stopped Due to Early Event Rates
Patients undergoing transcatheter aortic valve replacement (TAVR) randomized to rivaroxaban in the GALILEO trial experienced higher risk of all-cause death, thromboembolic events, and bleeding compared with patients who received antiplatelet therapy. The GALILEO trial was halted after an early peek of events at the data from the rivaroxaban (Xarelto; Bayer/Janssen) arm. These events included higher…
Immediate Electrocardiography After TAVI, the Simplest Way to Predict Conduction Disorders
Taking into account a simple 12-lead electrocardiography performed immediately after transcatheter aortic valve implantation (TAVI), removing the temporary pacemaker immediately is safe in patients without right bundle branch block who are in sinus rhythm with PR interval <240 ms and QRS interval <150 ms. In cases of atrial fibrillation, a QRS interval <140 ms also reassures the decision…
Ambulatory Continuous Monitoring in Patients with Left Bundle Branch Block After TAVI
The incidence of arrhythmic events up to a year after implantation is high and involves almost half the patients with complete left bundle branch block following the procedure. Significant bradyarrhythmias occur in up to one-fifth of the patients, half of whom ultimately require a pacemaker. These data support the idea of a cardiac monitoring device…
Predictors of Conduction Disturbances Requiring a Late Permanent Pacemaker
This analysis shows that baseline right bundle branch block and increased PR length after transcatheter aortic valve replacement (TAVR) are independent predictors of advanced conduction disturbances requiring late pacemaker implantation. A simple electrocardiography can detect these potentially fatal conduction disturbances that might happen more than 48 hours after TAVR. Data from consecutive TAVR patients from…
TCT 2018 | Mismatch After TAVR According to the TVT Registry
Prosthesis-patient mismatch (i.e. a difference between the size of the implanted prosthetic valve and the patient body size) in patients who undergo surgery is associated with worse outcomes. This may also apply to percutaneous prostheses, although that has not been well-studied yet. This work, presented at TCT 2018 and published simultaneously in JACC, analyzes this problem…
