“…Studies show that LV GLS directly correlates with postprocedural outcomes. 6 LV-GLS at baseline presented positive correlations with both LV-GLS and RV strain parameters at 3 months followup, but also a negative correlation with LVEF at follow-up, thus showing that single LV-GLS measurement performed before the procedure may be associated with both LV and RV remodeling after TAVR. Interestingly, in contrast to LVEF, none of the strain parameters correlated with age, demonstrating that GLS might lead to better understanding and more clear interpretation of ventricular mechanics in patients with aortic stenosis.…”

“…There are studies which showed that, even though the left ventricular ejection fraction remained unchanged, aortic valve replacement surgery improved the speckle tracking left ventricular analyzed parameters. 6 But, there are limited data regarding the timing of the reverse remodeling of the left and right ventricle following the TAVR procedure. Our study demonstrated a significant beneficial impact of TAVR procedure on LV myocardial mechanics, by analyzing the global longitudinal strain, in addition to the improvement of the LVEF in elderly patients with severe AS after TAVR.…”

Background Transcatheter aortic valve replacement (TAVR) became the leading therapeutic strategy for aortic valve replacement in older patients with severe symptomatic aortic stenosis. Echocardiographic parameters that mark the left ventricle and right ventricle reverse remodeling after the TAVR are not well established. The aim of the current study is to describe the dynamics of both left ventricle (LV) and right ventricle (RV) strain derived from speckle tracking echocardiography in elderly patients at 3-months after the TAVR procedure. Methods We enrolled 52 consecutive patients (77 ± 4.9 years old, median STS score of 3.1) who underwent transfemoral TAVR at our tertiary care center. All patients were evaluated at baseline and 3 months following TAVR. Results The LV global longitudinal strain (GLS) 3-month following TAVR was significantly improved compared with baseline values (−16 ±4.2% vs −16 ±4.2%; p < 0.001) but no significant changes in the RV GLS 3 and 6 segments model following TAVR were registered. The LV ejection fraction was significantly improved 3-months after the TAVR procedure. LV-GLS at baseline demonstrated a strong positive correlation with LV-GLS at 3 months (r = 0.69) and a moderate correlation with RV strain parameters (r = 0.38 and r = 0.56), but also a negative correlation with LVEF at follow-up (r=−0.61). Interestingly, in contrast to LVEF, none of the strain parameters correlated with age. NT-proBNP values were correlated with both LV-GLS (r = 0.37) and LVEF (r=−0.5) at baseline. However, at follow-up, baseline NT-proBNP values remained correlated only to LV-GLS at 3-months (r = 0.24), but the correlation was weak.

“…Além deste, os estudos avaliados por Stangenhaus C et al, (2017) observaram melhora da mecânica miocárdica em pacientes submetidos ao TAVI 12 meses após o procedimento, assim como apresentaram uma resposta positiva para a análise da deformação miocárdica circunferencial e da fração de ejeção.…”

A estenose aórtica é a valvopatia grave mais prevalente na população, caracterizada pela obstrução fixa da valva aórtica. Assintomática nos estágios iniciais, pode cursar com a tríade de dispneia, síncope e dor torácica. Como tratamento, a cirurgia de substituição da valva é uma das opções. METODOLOGIA: Trata-se de uma revisão narrativa, com pesquisas nas bases de dados SciELO, LILACS e PubMed e recorte temporal de 2016 a 2021. Os descritores utilizados foram "aortic valve stenosis", " transcatheter aortic valve replacement "e "indicators of morbidity and mortality", nas línguas inglesa e portuguesa. RESULTADOS: Os artigos analisados foram publicados em periódicos nacionais e internacionais. Foram selecionados artigos de revisões sistemáticas, ensaios clínicos, editorial, relatos de caso, estudos comparativos, estudos observacionais, revisão narrativa e estudos prognósticos. DISCUSSÃO: A bibliografia consultada afirma que o implante de valva aórtica transcateter -TAVI surgiu como um tratamento menos invasivo nos casos de estenose aórtica grave, sendo uma alternativa para pacientes com alto risco cirúrgico ou considerados 'inoperáveis'. CONCLUSÃO: De acordo com estudos, o uso de TAVI apresenta benefícios em alguns casos bem como tem impactos positivos na sobrevida de pacientes submetidos ao tratamento cirúrgico da estenose aórtica. Contudo, assim como qualquer procedimento tem várias possíveis complicações.
