ABSTRACT
Abstract

Background:

Three-dimensional (3D) echocardiography coupled with speckle-tracking echocardiographic (STE) capability is a novel methodology which has been demontrated to be useful for the assessment of left atrial (LA) volumes and functional properties. There is increased scientific interest on myocardial deformation analysis in adult patients with corrected tetralogy of Fallot (cTOF).

Objectives:

To compare LA volumes, volume-based functional properties and strain parameters between cTOF patients and age- and gender-matched healthy controls.

Methods:

The study population consisted of 19 consecutive adult patients with cTOF in sinus rhythm nursing at the University of Szeged, Hungary (mean age 37.9 ± 11.3 years, 8 men, who had repair at the age of 4.1 ± 2.5 years). They all had undergone standard transthoracic two-dimensional Doppler echocardiographic study extended with 3DSTE. Their results were compared to 23 age- and gender-matched healthy controls (mean age 39.2 ± 10.6 years, 14 men).

Results:

Increased LA volumes and reduced LA emptying fractions respecting cardiac cycle could be demonstrated in cTOF patients compared to controls. LA stroke volumes featuring all LA functions showed no differences between the 2 groups examined. LA global and mean segmental uni- and multidirectional peak strains featuring LA reservoir function were found to be diminished in adult patients with cTOF as compared to controls. Similarly to peak strains reduced global and mean segmental LA strains at atrial contraction characterizing atrial booster pump function could be demonstrated in cTOF patients as compared to controls.

Conclusions:

Significant deterioration of all LA functions could be demonstrated in adult patients with cTOF late after repair.
RESUMO
Resumo Fundamento Ecocardiografia tridimensional (3D) acoplada à técnica de speckle-tracking (3DSTE) é uma nova metodologia útil para a avaliação de volumes e propriedades funcionais do átrio esquerdo (AE). Há crescente interesse científico na análise da deformação miocárdica em adultos com tetralogia de Fallot corrigida (cTOF).

Objetivos:

Comparar os volumes de AE, propriedades funcionais baseadas no volume e parâmetros de strain entre pacientes com cTOF e controles saudáveis pareados por idade e sexo.

Métodos:

A população do estudo consistiu em 19 adultos com cTOF consecutivos, em ritmo sinusal, acompanhados na Universidade Szeged, Hungria (idade média 37,9 ± 11,3 anos; 8 homens; com correção cirúrgica aos 4,1 ± 2,5 anos de idade). Todos foram submetidos a ecocardiografia transtorácica bidimensional com Doppler padrão e 3DSTE. Os resultados foram comparados aos de 23 controles saudáveis pareados por idade e sexo (idade média 39,2 ± 10,6 anos; 14 homens).

Resultados:

Aumento dos volumes de AE e redução das frações de esvaziamento de AE em relação ao ciclo cardíaco foram demonstrados em pacientes com cTOF em comparação aos dos controles. Os volumes de ejeção de AE caracterizando todas as funções do AE não diferiram entre os dois grupos. Strains de AE global e segmentar médio uni- e multidimensional, caracterizando função de reservatório de AE, estavam diminuídos em adultos com cTOF em comparação aos de controles. À semelhança dos strains de pico, reduzidos strains de AE global e segmentar médio na contração atrial, caracterizando função de bomba atrial, foram demonstrados em pacientes com cTOF em comparação aos de controles.

Conclusões:

Demonstrou-se significativa deterioração das funções de AE em adultos com cTOF em fase tardia após correção.
