Background
Most patients who undergo tetralogy of Fallot (TOF) repair experience late right ventricle (RV) dysfunction due to pulmonary valve regurgitation (PVR). Cardiac magnetic resonance (CMR) is the gold standard method for evaluating RV during follow‐up. Global longitudinal strain (GLS) has been introduced as a novel method for the assessment of RV dysfunction. We aimed to compare the feasibility of GLS and CMR for assessing RV function after TOF repair.
Methods
We systematically reviewed the English literature using PubMed, SciELO and Google Scholar for articles published between January 1, 2015, and December 31, 2020. Articles evaluating RV function comparing by GLS and CMR after TOF repair were included.
Results
Nine studies including 465 patients were analyzed. Most patients were men (280; 60%), the male:female ratio was 1.5:1, and the age range was .8 to 57.7 years. The mean follow‐up time was 6 to 32 months. The correlation between RV GLS and RV ejection fraction (EF) by CMR was negative for the articles and varied from moderate to strong (r = ‐.45, r = ‐.60, r = ‐.76).
Conclusion
Right ventricle GLS can be considered for routine follow‐up of TOF repair patients, even though CMR remains the noninvasive gold standard method. Using a single parameter may not allow comparison of the accuracy of 3D RV EF by using CMR and GLS. Further studies with a larger number of patients undergoing TOF repair are required to evaluate the correlation between these examinations.
Este artigo buscou analisar as próteses valvares biológicas e mecânicas por meio de comparações associadas às suas diferentes durabilidades, riscos de desenvolver endocardite, tromboembolismo, eventos hemorrágicos, necessidade de reoperações e sobrevida a longo prazo, além da relação de custo e benefício de cada tipo de prótese valvar. As válvulas cardíacas mecânicas possuem como principal vantagem sua longa durabilidade, apresentando um número reduzido de reoperação comparadas as válvulas cardíacas biológicas, que sofrem desgaste maior com o tempo. O grande destaque recebido pelas válvulas cardíacas biológicas é relacionado a sua independência de medicamentos, algo que se apresenta como obstáculo pelas válvulas mecânicas devido à necessidade do uso de anticoagulante de forma vitalícia, ocasionado pela alta probabilidade de desenvolvimento de trombose na região valvar e, consequentemente, embolia, eventos que não ocorrem nas valvas biológicas. A eleição do tipo de prótese valvar deve ser feita de acordo com o perfil de cada paciente, levando em consideração suas individualidades, como idade, comorbidades, riscos de reoperação e sobrevida após operação, com a finalidade de promover um melhor prognóstico e qualidade de vida para esse grupo.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
