Ecocardiografía transesofágica tridimensional en la evaluación: guía y seguimiento de intervenciones cardíacas percutáneas

B. Vision transesofagica tridimensional post-procedimiento percutaneo, donde se observa el dispositivo Amplatzer que ocluye el orificio de entrada de la OI.A. Vision transesofagica tridimensional durante la guia ecocardiografica de reparacion percutanea de insuficiencia mitral con dispositivo MitraClip (MCLIP). Se observa paso del cateter (CAT) desde auricula derecha (AD) hacia auricula izquierda (AI) a traves del tabique interauricular. Abreviaciones, Ao:aorta; VM: valvula mitral.B. Vision tranesogagica tridimensional de la valvula mitral vista desde la AI. Se observa dispositivo MitraClip posicionado entre segmentos A2 y P2 de valvula mitral.

Remodelado auricular adverso en atletas de alto rendimiento: Estudio de deformación auricular con speckle tracking 2D

Atletas de alto rendimiento tienen un riesgo aumentado de desarrollar fibrilacion auricular (FA) y flutter. La dilatacion y disfuncion auricular po-drian ser el sustrato subyacente para este incremento en el riesgo. El objetivo fue analizar y relacionar el tamano y deformacion auricular en un grupo seleccionado de at-letas y en pacientes con FA paroxistica.

943 Impact of underlying cardiopathy on left ventricular remodelling after cardiac resynchronization therapy

, p<0.02), in the office diastolic blood pressure (83.0±6.2 vs 77.0±7.5 mm Hg, p<0.008) and heart rate (76.1±14.0 vs 66.3±9.7 bpm, p<0.02). No differences were found in left ventricular diameters, volumes, mass, meridional and circumferential end-systolic stress, total peripheral resistence, stroke volume and cardiac output. The relative wall thickness (RWT) was significantly increase in black (0.42±0.04 vs 0.36±0.05, p<0.0001), suggesting a tendency to a concen- tric remodelling. The left systolic function estimated by conventional param- eters was unchanged. Doppler analysis of tissue kinetics showed a signifi- cant increase in black subjects of septal S and E waves, as peak velocity (pv) and time velocity integral (tvi), when compared with white subjects. The MPI in black subjects was significantly increase (0.46±0.05 vs 0.39±0.05, p<0.0003), due to a significant prolongation of ICT (62.1±19.1 vs 51.4±9.9 msec). A significant correlation between MPI and RWT (r=0.54, p<0.001) and left ventricular mass (r=0.54, p<0,001) respectively were demonstrated. Besides, MPI correlate with Spv (r=0.55, p<0.001) and Stvi (r=0.38, p<0.001) waves. In conclusion our data confirm that MPI is increase in black healthy subject and is geometry-dependent, in contrast with current literature. Besides, we found correlations between MPI and systolic indexes derived from DTE. These findings also suggest that racial differences in left ventricular perfor- mance and systolic function exist even in absence of other conventional echocardiographic changes.
