Aortic Valve Replacement in Asymptomatic Patients

Aortic Valve Replacement in Asymptomatic Patients - TAVR vs Surgical

Current guidelines admit, however, that the management of patients with asymptomatic AS (including a normal exercise test) and normal left ventricular function remains controversial. Decision-making requires careful weighing of risk and benefit. In this regard, the fact that catheter interventional treatment of AS is rapidly evolving and recent data demonstrate that the risk of both, surgical AVR and transcatheter aortic valve implantation (TAVI) have markedly decreased over the years has an obvious impact as this may change the threshold to intervene in asymptomatic patients when weighing risk vs. potential benefit. On the other hand, the complexity of long-term planning considering the consequences for later re-interventions, access to coronary arteries after TAVI, and other aspects have been recognized. New important data including randomized controlled trials comparing watchful waiting vs. early surgery in asymptomatic AS have also been provided. Thus, it appears timely to revisit the pro and cons of whether all patients with asymptomatic severe AS need a valve replacement.

Learn Echocardiography | Standard Protocol for Performing Comprehensive Echocardiogram | Explained with Images and Videos

If you are just starting to learn echocardiography, you will find that learning the full echo examination protocol will be immensely useful. The full protocol will provide a solid foundation for your career in echo. I personally found that once I could execute the standard protocol flawlessly, I was able to add and refine additional echo scanning skills while deepening my understanding of the purpose of each echo image. The echo protocol illustrated in this article is the same one we currently use for all our patients in the hospital and meets or exceeds the standards of American Society of Echocardiography (ASE) for an adult echocardiography examination. The protocol presented here is meant as a guideline and does not cover every aspect (such as off axis views) of an echo examination. Also other hospitals will probably have slight variations of this protocol depending on the lab's needs, which is normal. This article's main purpose is to provide a solid foundation for ...

The 1-3-6-12-day rule is a known consensus with graded increase in delay of anticoagulation between 1 and 12 days after onset of ischemic stroke or transient ischemic attack(TIA), according to neurological severity based on European expert opinions. However, this rule might be somewhat later than currently used in a real-world practical setting.
