Approximately 10% of patients who undergo transcatheter aortic valve replacement (TAVR) are readmitted for an acute coronary syndrome after a mean follow-up of 25 months. Male sex, prior coronary artery disease, and (surprisingly and hard to explain) nontransfemoral approach were independent predictors of acute coronary syndrome after TAVR, an event associated with high midterm mortality.

Strategies to Reduce Acute Kidney Injury in Angioplasty
The title of this article leads us to think that we will find a list of things that we can do to reduce kidney injury. However, (unfortunately) sodium bicarbonate showed no benefit over saline and n-acetylcysteine showed no benefit over a placebo for the reduction of kidney damage after coronary angioplasty. Among the protective measures<a href="https://solaci.org/en/2018/12/06/strategies-to-reduce-acute-kidney-injury-in-angioplasty/" title="Read more" >...</a>
Aspirin, Bleeding and Cardiovascular Events in Healthy Elderly
The ASCEND and ARRIVE trials -presented at the European Cardiology Congress and published in The New England Journal of Medicine (NEJM) and The Lancet respectively- have put against the ropes the indication of aspirin in the context of primary prevention. The ASPREE trial, recently published in the NEJM, appears to have definitely overthrown aspirin, since<a href="https://solaci.org/en/2018/12/04/aspirin-bleeding-and-cardiovascular-events-in-healthy-elderly/" title="Read more" >...</a>
Is TAVR at Hospitals Without Backup Cardiovascular Surgery Feasible?
Patients undergoing transcatheter aortic valve replacement (TAVR) at hospitals without cardiovascular surgery available are at significantly higher risk. That in itself is a call for attention; however, a propensity-matched analysis shows that the short- and long-term mortality rates are similar among patients treated at hospitals with and without cardiovascular surgery backup. This debate emerged a<a href="https://solaci.org/en/2018/12/03/is-tavr-at-hospitals-without-backup-cardiovascular-surgery-feasible/" title="Read more" >...</a>
Aortic Stenosis and Dialysis: Is TAVR the Strategy of Choice?
Courtesy of Dr. Carlos Fava. TAVR has been shown beneficial in high and moderate risk patients, but there is a group of patients that require dialysis on account of kidney deterioration. This comorbidity is due to bad cardiovascular evolution associated to diabetes, bleeding and thromboembolic events. For some time, we have been using an<a href="https://solaci.org/en/2018/12/03/aortic-stenosis-and-dialysis-is-tavr-the-strategy-of-choice/" title="Read more" >...</a>
CoreValve US Pivotal High Risk Trial: at 5 years, similar results
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<a href="https://solaci.org/en/2018/11/21/corevalve-us-pivotal-high-risk-trial-at-5-years-similar-results/" title="Read more" >...</a>
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<a href="https://solaci.org/en/2018/11/13/surprises-in-the-physiopathology-of-critical-ischemia/" title="Read more" >...</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<a href="https://solaci.org/en/2018/11/09/differences-in-stroke-between-tavr-and-savr-in-intermediate-risk-patients/" title="Read more" >...</a>
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<a href="https://solaci.org/en/2018/11/09/tavr-in-low-risk-patients-with-zero-mortality-and-zero-stroke/" title="Read more" >...</a>
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<a href="https://solaci.org/en/2018/11/02/how-to-predict-post-tavr-quality-of-life-in-real-world-patients/" title="Read more" >...</a>
