conferenceObject Quality of life and physical capacity after long-term right ventricular pacing in young adults with congenital atrioventricular block(2012) SILVA, K. R.; COSTA, R.; OLIVEIRA JR., R. M.; MARTINELLI FILHO, M.; LACERDA, M. S.; HUANG, A.; ROSSI, M. B.; MATHIAS JR., W.; PIETROBON, R.; STOLF, N. A. G.Background: Although several studies have demonstrated the deleterious consequences of chronic right ventricular (RV) pacing on ventricular function and synchronicity, its effects on health-related quality of life (HRQL) and physical capacity remains uncertain. Objectives: To evaluate the effect of RV pacing on HRQL and physical capacity of children and young adults with congenital complete atrioventricular (AV) block. Methods: Fifty consecutive patients with permanent RV cardiac pacing due to congenital AV block and under clinical follow-up for more than one year were enrolled. Multidimensional HRQL was assessed with the Short Form-36 Health Survey (SF-36) and Child Health Questionnaire (CHQ-PF50). Physical capacity was tested by the 6-minute walk distance test (6MWD). The scores for each domain and the distance performed at the 6MWD test were compared with demographic and clinical characteristics of patients, using the Student’s t-test and Qui-squaretest. Results: Domains presenting lower scores were Vitality (63.0±20.6), Pain(66.5±25.1) and Mental Health (67.3±20.4) in the SF-36 questionnaire; General Health Perceptions (64.0±15.0) and Parental Impact-Emotional (69.0±30.0) in the CHQ-PF50. Female gender (P=0.026), DDD pacing mode (0.008) and normal left ventricular ejection fraction (0.002) were associated with higher quality of life scores. The average distance performed at the 6MWD test was 677,2 meters (454,5 to 852,8). The 6MWD showed significant association with age (P=0.004), normal ventricular function (P= 0.031) and the absence of cardiovascular drugs use (P= 0.018). Conclusions: The results of this analysis indicated that chronic RV pacing did not affect the HRQL and physical capacity of young patients. Female gender, DDD pacing, normal ventricular function and the absence of cardiovascular medications were associated with better HRQL scores and with better results at 6MWD test.conferenceObject Predictors of contractile reserve on dobutamine stress echocardiography in patients with classical low-flow, low-gradient aortic stenosis(2019) ROSA, V.

Objectives: Evaluation of the role of hypercholesterolemic diet in the determination of the hemodynamics patterns by echocardiography. Methods: Sixty three anesthetized rats were subjected to occlusion of the left anterior descending (LAD) coronary artery and divided in six groups: G1–just normal diet (ND); G2–ND and treatment with rosuvastatim for 30 days began after infarct and G3–ND and 30 days previously to infarct treated with rosuvastatim until 30 days after it; G4 –just hypercholesterolemic diet (HD); G5–HD and treatment with rosuvastatim for 30 days began after infarct and G6 –HD and 30 days previously to infarct treated with rosuvastatim until 30 days after it. Echocardiography was performed using bidimensional image in the paraesternal long axis. The planimetry of the left ventricle areas in the end of the diastole (LVEDA) and systole (LVESA) were realized before the infarct (pre) and 30 days after the infarct (post) . A p value<0.05 was considered significant. Conclusion: The hypercholesterolemic diet worst the hemodynamics parameters–LVEDA and LVESA - in comparison with the normocholesterolemic group treated with rosuvastatim.conferenceObject Short- and Long-term Outcomes After Surgical Aortic Valve Replacement in Patients With Classical Low-flow, Low-gradient Aortic Stenosis(2019) ROSA, Vitor E.; RIBEIRO, Henrique B.; SAMPAIO, Roney O.; MORAIS, Thamara C.; ROSA, Marcela E.; SANTIS, Antonio S.
