Benefit of early aortic valve surgery in asymptomatic, severe AS
Nature Reviews Cardiology, Published online: 24 November 2021; doi:10.1038/s41569-021-00656-8Early surgical aortic valve replacement in asymptomatic patients with severe aortic stenosis reduces the risk of all-cause death, acute myocardial infarction, stroke or unplanned hospitalization for heart failure compared with conservative care and surgical aortic valve replacement only after symptom onset, according to findings from the AVATAR trial.

Conclusions: In asymptomatic patients with severe AS, early surgery reduced a primary composite of all-cause death, acute myocardial infarction, stroke or unplanned hospitalization for heart failure compared with conservative treatment. This randomized trial provides preliminary support for early SAVR once AS becomes severe, regardless of symptoms.PMID:34779220 | DOI:10.1161/CIRCULATIONAHA.121.057639

Transcatheter aortic valve implantation results are not superimposable to surgery in patients with aortic stenosis at low surgical risk
CONCLUSIONS: TAVI and SVAR in the treatment of AS in the patients at low surgical risk are not superimposable. In particular, if 30-day and 1-year mortality, major bleeding and acute kidney injury were significantly lower for TAVI, the need of new PM implantation and paravalvular leak were significantly lower in SAVR. Consequently, we suggest the need of more trials to evaluate the effectiveness of TAVI as routine therapeutic procedure in the treatment of patients with low surgical risk AS.PMID:34622437 | DOI:10.5603/CJ.a2021.0114

New frontiers for improving outcomes after transcatheter aortic valve implantation: the role of the conduction system and the impact of pacemakers
Transcatheter aortic valve implantation (TAVI) is at least as safe and effective as surgical aortic valve replacement (SAVR) in patients with severe symptomatic aortic stenosis for the endpoints of all-cause mortality, stroke and heart failure hospitalizations across the spectrum of surgical risk1,2. Despite iterative advances in technology and refinements in procedural technique, conduction disturbances are not infrequent and occur more commonly after TAVI than after surgery. In the most recent low-risk randomized trials2,3 comparing TAVI to SAVR, the rates of permanent pacemaker implantation (PPI) were 6.6% with the ball...

On Left Ventricle Stroke Work Efficiency in Children with Moderate Aortic Valve Regurgitation or Moderate Aortic Valve Stenosis
In this study, we explore the use of a patient-specific mathematical model to introduce a new evaluative parameter of LV performance in patients with moderate aortic valve disease. Synthetic patient data (N = 520) representing healthy patients, and patients with modAS or modAR were first generated. Then, data from twenty-five pediatric patients were included in this study (healthy = 9; moderate AS = 8; modAR = 8). The effect of modAS or modAR on LV performance was evaluated by LV strok e work (LVSW) efficiency, a new non-invasive parameter. The results demonstrate that healthy patients possess a very high L...
