Background: 2D speckle tracking echocardiography (2DSTE) is superior to standard echocardiography in the assessment of subtle right ventricle (RV) systolic dysfunction. In this study we aimed to: 1) test the hypothesis that 2DSTE may unveil subtle RV systolic dysfunction in patients with Fabry disease; 2) investigate whether the physiologic difference between the 3-segment (RV-FWS) and the 6-segment (RV-GLS) RV strain (∆RV strain) is preserved in Fabry patients. Methods and results: Standard echocardiography and 2DSTE were performed in 49 Fabry patients and 49 age- and sex-matched healthy controls. Fabry patients were divided in two groups according to the presence/absence of left ventricular hypertrophy (LVH+: left ventricular wall thickness > 12 mm, 49% of total Fabry patients). RV systolic function assessed by standard echocardiography was normal in the majority of Fabry patients (92%) while RV-GLS and RV-FWS were impaired in about 40%. RV-GLS and RV-FWS were significantly worse in patients LVH+ vs LVH- and vs controls (RV-GLS: LVH+ vs LVH-: −18.4 ± −4.3% vs −23.8 ± −3.1% p<0.001; LVH+ vs controls: −18.4 ± −4.3% vs −23.9 ± −2.8% p<0.001; RV-FWS: LVH+ vs LVH-: −21.8 ± −5.3% vs −26.7 ± −3.8% p = 0.002, LVH+ vs controls −21.8 ± −5.3% vs −26.8 ± −3.9% p<0.001). No difference was found between LVH- patients and controls in both RV-GLS (p = 0.65) and RV-FWS (p = 0.79). ∆RV strain was similar among the groups. Conclusions: In Fabry cardiomyopathy impaired RV-GLS and RV-FWS is a common finding, while RV strain is preserved in Fabry patients without overt cardiac involvement. The physiologic difference between RV-FWS and RV-GLS is maintained in Fabry patients, regardless of the presence of cardiomyopathy.
