Aortic Valve Leaflet Rupture Causing Delayed Left Main Coronary Ostial Obstruction During Valvuloplasty Preceding TAVR
Source : https://www.sciencedirect.com/science/article/pii/S266608492100930X?via=ihub
A 69-year-old man with mediastinal radiation history underwent balloon valvuloplasty before transcatheter aortic valve replacement, which caused aortic leaflet rupture leading to unstable severe aortic regurgitation and subsequent left main...
Conclusion/Relevance: The risk of focal leaflet rupture is elevated in patients with radiation-induced valvular heart disease because the fibrotic thickening, scarring, retraction, and focal calcifications involve the medial and basal sections of the valve, rather than the valvular tips (5,6). Here, we presented a rare case of AV leaflet...
Efficient detection of aortic stenosis using morphological characteristics of cardiomechanical signals and heart rate variability parameters - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/34893693/
Recent research has shown promising results for the detection of aortic stenosis (AS) using cardio-mechanical signals. However, they are limited by two main factors: lacking physical explanations for decision-making on...
Conclusion/Relevance: Recent research has shown promising results for the detection of aortic stenosis (AS) using cardio-mechanical signals. However, they are limited by two main factors: lacking physical explanations for decision-making on the existence of AS, and the need for auxiliary signals. The main goal of this paper is to address these...
A case of ruptured giant sinus of Valsalva aneurysm into the right ventricle in a patient with both atrial and ventricular septal defects - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/34887201/
Sinus of Valsalva aneurysm (SOVA) is a rare cardiac defect. In most cases, SOVA presents as an incidental finding during cardiac imaging. A dreadful complication of SOVA is spontaneous rupture,...
Conclusion/Relevance: Sinus of Valsalva aneurysm (SOVA) is a rare cardiac defect. In most cases, SOVA presents as an incidental finding during cardiac imaging. A dreadful complication of SOVA is spontaneous rupture, most commonly occurring into the right side of the heart resulting in an abrupt or insidiously progressive congestive heart...

Conclusions: Computer simulation may identify patients who are at a higher risk for death after TAVR.
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.
