Transcatheter aortic valve-in-valve implantation for failed surgical bioprostheses: results from Polish Transcatheter Aortic Valve-in-Valve Implantation (ViV-TAVI) Registry - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/34845900/
Introduction: Transcatheter aortic valve-in-valve implantation (ViV-TAVI) emerged recently as an alternative to re-do surgery for patients with failed surgical aortic valve (SAV). Objectives: To evaluate the safety and efficacy of...
Conclusions: Transcatheter treatment of failed SAV is becoming more frequent, showing the best hemodynamic effect with the use of supra-annular TAV and improved procedural as well as clinical results with the introduction of 2nd generation TAV.

Purpose Leaflet thrombosis is a significant adverse event after transcatheter aortic valve (TAV) replacement (TAVR). The purpose of our study was to present a semi-empirical, mathematical model that links patient-specific...
Conclusion: A predictive model relating likelihood of valve thrombosis using Г in the NS was developed with promising sensitivity and specificity. With further studies and improvements, this predictive technology may lead to alerting physicians on the risk for thrombus formation following TAVR.

Heart Rate Induced Dynamic Coronary Ischemia Secondary to Aortic Valve Insufficiency from a Diminutive Aortic Valve Leaflet: Diagnosis and Repair - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/34820700/
Hemodynamically significant congenital obstruction of the coronary arteries is a rare phenomenon. The potential etiology of these obstructions is variable including coronary os stenosis, occlusive fibrous webs, or a dysplastic...
Conclusion/Relevance: We present a case of an infant presenting in heart failure secondary to dynamic coronary artery insufficiency from a diminutive aortic valve leaflet and aortic sinus and variable levels of aortic valve insufficiency based on heart rate.
