Many hands make light work. Echocardiography and computed tomography results from the Tricuspid Regurgitation IMAging (TRIMA) study

Abstract Background Anatomic knowledge of the tricuspid valve (TV) is first step in diagnostic algorithm patients with regurgitation (TR), who are candidates for transcatheter intervention (TTVI). Currently, echocardiography and computed tomography (CT) available instruments to study TV anatomy, guide decision-making process support development novel therapies. Purpose The Tricuspid Regurgitation IMAging (TRIMA) aimed correlate CT parameters commonly used echocardiographic variables. Methods This prospective, single-center enrolled 22 consecutive TR equal or greater than severe (≥3+). All underwent transthoracic echocardiogram (TTE), transesophageal (TEE) cardiac study, order obtain anatomical dimensions annulus quantification right-chambers remodeling function. Novel scan measurements were analyzed. Correlation between on imaging was assessed. Results Severe (3+) present 27.4% patients, massive (4+) 4.8% torrential (5+) 3.2%. mean right ventricle (RV) length, RV mid diameter, atrium area 60.81±9.11 mm, 41.27±7.67 mm 31.72±9.66 cm2, respectively. annular plane excursion, fractional change, longitudinal myocardial velocity (S') 16.09±3.25 33.36±9.47% 9.18±1.94 cm/sec, obtained by generally observed reduce from diastole systole, except eccentricity, angles distance postero-septal antero-posterior commissure centroid commissure. A Kruskal-Wallis test showed a stepwise increase regurgitant orifice (AROA) values across expanded grades TEE, χ2(2)=6,466, p=0.039. Using Pearson correlation coefficient, we found relationship AROA grade (r=0.593; p<0.004), as well ARO-perimeter (r=0.470; p<0.027). Additionally, significant septal lateral diameter TEE (r=0.637; p=0.001). Anyway, no correlations variables function assessed echocardiogram, systo-diastolic variability Conclusions Standard provide invaluable information about anatomy right-chambers, an accurate TR. Conventional derived may up assessment complex morphology apparatus, thanks high spatial resolution technique. Therefore, integrated multimodality key point screening TTVI.
