Transcatheter aortic valve replacement (TAVR) is an evolving method which has become the treatment of choice in high-risk patients with severe aortic stenosis. Unlike TAVR, the experience with transcatheter mitral valve replacement (TMVR) remains at an early stage because of challenges of valve development and possible complications such as valve displacement and subsequent left ventricular outlet tract (LVOT) obstruction. Here we report a case of transcatheter double valve-in-valve replacement (TDVIVR) in a patient with severe mitral and aortic bioprosthetic valve stenosis, followed by an extensive literature review of the latest techniques and challenges in this field.
Marijuana has become one of the most commonly used recreational drug. Much of its use, is based upon its belief that it is relatively "safe" especially when compared to other drugs. This case, among others, highlights the fact that although marijuana has been utilized for many years in many cultures for many medical reasons, it does not come without risk. Specifically, we like to focus on cardiovascular risk associated with marijuana use. Relatively speaking, extensive research has not been done to localize marijuana and the specific mechanisms by which it can cause cardiovascular morbidity and mortality. However, it is also not an undocumented phenomenon. There have been varieties of case reports as well as studies, which have studied the cardiovascular toxicity, which are associated with marijuana use. Such toxicities include that of Acute Myocardial Infarction (AMI), vasospasm, LV thrombus among others. Here we present one such presentation of a patient with coronary vasospasm presenting as NSTEMI soon after heavy marijuana use.
Transradial approach for cardiac catheterization is a viable alternative to transfemoral approach given its ease of access, lessened complication risk, and post procedural comfort for patients. Radial pseudoaneurysm presents as a rare complication in less than 1% of these procedures. The use of external compression banding is an approach that shows promise as a noninvasive attempt towards resolving this complication. However, it has been documented in very few reports. We describe a case of an 82-year-old woman who underwent transradial approach to cardiac catheterization, and developed a radial pseudoaneurysm following the procedure as confirmed by Doppler ultrasonography. We used compressive banding as a technique to attempt to resolve this radial pseudoaneurysm. Following a strict protocol of pneumatic banding, repeat ultrasonography revealed complete resolution of radial pseudoaneurysm. This case highlights a potentially noninvasive technique that could serve as a first-line approach towards resolving this rare phenomenon.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
