Conclusions: Non-invasive myocardial work may allow better understanding of myocardial function and energetics than afterload-dependent echocardiographic parameters in chronic AR with preserved LVEF.
5-Year outcomes after transcatheter aortic valve implantation: Focus on paravalvular leakage assessed by echocardiography and hemodynamic parameters - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/35043554/
Objectives: We sought to assess the impact of echocardiographic and hemodynamic grading of paravalvular leakage (PVL) after transcatheter aortic valve implantation (TAVI) on the prediction of 5-year mortality. PVL after...
Conclusions: Even mild PVL assessed by echocardiography was an independent predictor for 5-year survival, whereas hemodynamic measurements did not help to identify PVLs that are relevant to 5-year survival.
Safety and Efficacy of Myval Implantation in Patients with Severe Bicuspid Aortic Valve Stenosis-A Multicenter Real-World Experience - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/35054137/
Bicuspid aortic valve (BAV) is the most common valvular congenital anomaly and is apparent in nearly 50% of candidates for AV replacement. While transcatheter aortic valve implantation (TAVI) is a...
Conclusion/Relevance: While transcatheter aortic valve implantation (TAVI) is a recommended treatment for patients with symptomatic severe aortic stenosis (AS) at all surgical risk levels, experience with TAVI in severe bicuspid AS is limited. TAVI in BAV is still a challenge due to its association with multiple and complex anatomical...
A-Test Method for Quantifying Structural Risk and Learning Capacity of Supervised Machine Learning Methods - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/35062109/
This paper presents an original method for studying the performance of the supervised Machine Learning (ML) methods, the A-Test method. The method offers the possibility of investigating the structural risk...
Conclusion/Relevance: The datasets comprise of children cases with a normal heart condition as well as 4 pathological cases: aortic stenosis, ventricular septal defect, mitral regurgitation, and pulmonary stenosis. It is observed that the A-Test method provides further comprehensive and more realistic information about the performance of the...
Retrieving a lost needle in the descending aorta during hemi-arch replacement - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/35014878/
A 73-year-old man diagnosed with moderate aortic insufficiency and dilatation of the aortic root and ascending aorta underwent a modified Bentall procedure and hemi-arch aortic replacement. During open distal anastomosis...
Relevance: A 73-year-old man diagnosed with moderate aortic insufficiency and dilatation of the aortic root and ascending aorta underwent a modified Bentall procedure and hemi-arch aortic replacement. During open distal anastomosis of the ascending aorta, the surgical needle was lost.
