RESUMO
Unidentified heart valve disease is associated with a significant morbidity and mortality. It has therefore become important to accurately identify, assess and monitor patients with this condition in order that appropriate and timely intervention can occur. Although echocardiography has emerged as the predominant imaging modality for this purpose, recent advances in cardiac magnetic resonance and cardiac computed tomography indicate that they may have an important contribution to make. The current review describes the assessment of regurgitant and stenotic heart valves by multimodality imaging (echocardiography, cardiac computed tomography and cardiac magnetic resonance) and discusses their relative strengths and weaknesses.
Doenças valvares cardíacas não identificadas são associadas com significativas taxas de morbidade e mortalidade. Dessa forma, é importante que os pacientes com essa condição sejam corretamente identificados, investigados e monitorizados para que a apropriada intervenção seja feita a tempo. Contudo, a modalidade ecocardiográfica surgiu predominantemente com esta finalidade, recentes avanços em ressonância magnética cárdica e tomografia computadorizada cardíaca indicam que provavelmente ambos tenham importante contribuição. A atual revisão descreve a avaliação das válvulas cardíacas regurgitantes e estenosadas através de multimodalidade (diversos tipos) de imagens (ecocardiografia, tomografia computorizada cardíaca e ressonância magnética cardíaca), promovendo a discussão de seus pontos positivos e negativos.
