Transcatheter valvular therapies in patients with left ventricular assist devices
Source : https://www.frontiersin.org/articles/10.3389/fcvm.2023.1071805/full
Aortic, mitral and tricuspid valve regurgitation are commonly encountered in patients with continuous-flow left ventricular assist devices (CF-LVADs). These valvular heart conditions either develop prior to CF-LVAD implantation or are...
Conclusions/Relevance: In this review, we will present the pathophysiology of valvular heart disease in the setting of CF-LVAD support to help us understand the underlying rationale of these potential complications. We will then outline the current recommendations for the management of valvular heart disease in patients with CF-LVAD and...
Consensus statement on aortic valve replacement via an anterior right minithoracotomy in the UK healthcare setting
Source : https://openheart.bmj.com/content/10/1/e002194
The wide uptake of anterior right thoracotomy (ART) as an approach for aortic valve replacement (AVR) has been limited despite initial reports of its use in 1993. Compared with median...
Relevance: In this statement, a consensus agreement is outlined that describes the potential benefits of the ART AVR. The technical considerations that require specific attention are described and the initiation of an ART programme at a UK centre is recommended through simulation and/or use of specialist instruments in conventional cases.
A Fatal Case of Staphylococcus capitis Endocarditis in a Patient With Transcatheter Aortic Valve Replacement - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/36994272/
Transcatheter aortic valve replacement (TAVR) has evolved to become a standard management modality for high-risk, moderate, and even low-risk patients with symptomatic aortic stenosis. Infective endocarditis (IE) after a TAVR...
Relevance: Here we present a man in his 60s who presented to our facility for evaluation of fever and shortness of breath. He was subsequently diagnosed with S. capitis TAVR-IE. He was not considered a surgical candidate and was treated medically for IE with a fatal outcome.

Conclusion: Although CA was rarely needed in patients after TAVR, selective diagnostic CA was possible in the overwhelming majority of patients. PCI was performed successfully in all cases, without complications.
Acute expansion of nitinol-based self-expandable device in patients undergoing transfemoral aortic valve implantation
valves after implantation. Methods This is a single-site prospective registry including patients undergoing transcatheter aortic valve replacement (TAVR) with a widely used second-generation nitinol-based self-expandable device (Evolut R, Medtronic, Minneapolis,...
Conclusion: This is the first study to have documented a significant degree of the Evolut R self-expandable valve expansion after deployment. However, further studies are required to assess the short- and long-term time course of self-expandable valve enlargement and the clinical relevance of this finding.
