“…5 O presente estudo propõe a avaliação da função diastólica com base na análise da movimentação longitudinal do ventrículo esquerdo (VE) quantificada pela ressonância magnética cardíaca (RMC). 6 A população do estudo consiste em três grupos, de acordo com o estresse hemodinâmico: estenose aórtica (aumento importante da pós-carga), insuficiência aórtica (aumento consistente da pré-carga), ambas valvopatias comparadas com um grupo saudável. As valvopatias em conjunto formaram um grupo comparativo com o controle.…”

“…No entanto, a necessidade de melhorias no pós-processamento de imagem e nos tempos de aquisição, somada à limitada disponibilidade e ao relativo alto custo dos softwares empregados, cerceiam a maior abrangência dessas tecnologias relativamente novas na prática clínica. 7 É nesse contexto que o elegante estudo de Ribeiro et al 6 se insere e tem sua maior força: no custo-benefício de quatro variáveis obtidas de maneira simples e rápida no plano de quatro câmaras para avaliação indireta da disfunção diastólica, sem necessidade de sequências específicas adicionais ou uso de programas exclusivos. No entanto, antes de propor a incorporação desta técnica à rotina clínica, algumas importantes considerações metodológicas são imperativas.…”

Background: Left ventricular (LV) systolic diastolic function is prognostic in cardiovascular diseases and can be assessed via global longitudinal strain (GLS) on echocardiography and cardiac magnetic resonance (CMR). However, GLS by CMR requires the use of expensive software. Longitudinal linear displacement (LLD) may be a simple and inexpensive alternative to GLS, but the two have not been systematically compared. Objective: To compare LLD with GLS and LV ejection fraction (LVEF) in aortic valve disease patients and controls. Methods: We included 44 participants (26 with aortic valve disease, 19 controls). GLS was determined using CVI42 software (Circle Cardiovascular Imaging), while the LLD linear measurements of the distance between the base/apex of the LV included maximum displacement (MD), maximum velocity in early diastole (MVED), atrioventricular junction velocity in diastasis (VDS), and VDS/MVED ratio. Results: DM and MVED were correlated with GLS (r=0.69 and r=0.65, respectively) and LVEF (r=0.47 and r=0.57, p<0.001 for both). DM and MVED showed areas under the receiver operating characteristic curve (AUC) of 0.88 and 0.91, and at the best cut-off point (-0.13 and 0.66), sensitivities of 72.43% and 57.14% and specificities of 80.65% and 87.10%, respectively, compared to GLS. Using LVEF as a reference, we obtained AUC of 0.70 and 0.82, and at the best cut-off point (-0.11 and 0.61), sensitivities of 75.00% and 50.00% and specificities of 72.97% and 78.38%, respectively. Conclusion: LLD demonstrated similar performance to that of GLS. MD derived from LLD was the best parameter during systole, while MVED was the best during diastole. Our findings demonstrate the routine, quick, and inexpensive assessment of diastolic function on CMR.

“…The advanced analysis of cardiac fibers deformability offered by the Cardiovascular Magnetic Resonance (CMR) feature tracking (CMR-FT) technique enables the accurate and reproducible assessment of early modifications in both LV systolic and diastolic function [ 11 – 13 ]. CMR-FT is a post-processing technique applied to cine steady-state free precession (cine-SSFP) sequences, which analyzes myocardial longitudinal and circumferential strain parameters throughout all phases of cardiac cycle [ 14 ].…”

To assess the impact of regurgitant jet direction on left ventricular function and intraventricular hemodynamics in asymptomatic patients with bicuspid aortic valve (BAV) and mild aortic valve regurgitation (AR), using cardiac magnetic resonance (CMR) feature tracking and 4D flow imaging. Fifty BAV individuals were retrospectively selected: 15 with mild AR and posterior regurgitation jet (Group-PJ), 15 with regurgitant jet in other directions (Group-nPJ) and 20 with no regurgitation (Controls). CMR protocol included cine steady state free precession (SSFP) sequences and 4D Flow imaging covering the entire left ventricle (LV) cavity and the aortic root. Cine-SSFP images were analyzed to assess LV volumes, longitudinal and circumferential myocardial strain. Circumferential and longitudinal peak diastolic strain rate (PDSR) and peak diastolic velocity (PDV) were reduced in group PJ if compared to group nPJ and control group (PDSR = 1.10 ± 0.2 1/s vs. 1.34 ± 0.5 1/s vs. 1.53 ± 0.3 1/s, p:0.001 and 0.68 ± 0.2 1/s vs. 1.17 ± 0.2 1/s vs. 1.05 ± 0.4 1/s ; p < 0.001, PDV = − 101.6 ± 28.1 deg/s vs. − 201.4 ± 85.9 deg/s vs. − 221.6 ± 67.1 deg/s; p < 0.001 and − 28.1 ± 8 mm/s vs. − 38.9 ± 11.1 mm/s vs. − 43.6 ± 14.3 mm/s, p < 0.001, respectively), whereas no differences have been found in systolic strain values. 4D Flow images (available only in 9 patients) showed deformation of diastolic transmitral streamlines direction in group PJ compared to other groups. In BAV patients with mild AR, the posterior direction of the regurgitant jet may hamper the complete mitral valve opening, disturbing transmitral flow and slowing the LV diastolic filling.
