    IntroductionClassical low-flow, low-gradient aortic stenosis (LFLG-AS) is an advanced stage of aortic stenosis, which has a poor prognosis with medical treatment and a high operative mortality after surgical aortic valve replacement (SAVR). There is currently a paucity of information regarding the current prognosis of classical LFLG-AS patients undergoing SAVR and the lack of a reliable risk assessment tool for this particular subset of AS patients. The present study aims to assess mortality predictors in a population of classical LFLG-AS patients undergoing SAVR.MethodsThis is a prospective study including 41 consecutive classical LFLG-AS patients (aortic valve area & LE;1.0 cm(2), mean transaortic gradient <40 mmHg, left ventricular ejection fraction <50%). All patients underwent dobutamine stress echocardiography (DSE), 3D echocardiography, and T1 mapping cardiac magnetic resonance (CMR). Patients with pseudo-severe aortic stenosis were excluded. Patients were divided into groups according to the median value of the mean transaortic gradient (& LE;25 and >25 mmHg). All-cause, intraprocedural, 30-day, and 1-year mortality rates were evaluated.ResultsAll of the patients had degenerative aortic stenosis, with a median age of 66 (60-73) years; most of the patients were men (83%). The median EuroSCORE II was 2.19% (1.5%-4.78%), and the median STS was 2.19% (1.6%-3.99%). On DSE, 73.2% had flow reserve (FR), i.e., an increase in stroke volume & GE;20% during DSE, with no significant differences between groups. On CMR, late gadolinium enhancement mass was lower in the group with mean transaortic gradient >25 mmHg [2.0 (0.0-8.9) g vs. 8.5 (2.3-15.0) g; p = 0.034), and myocardium extracellular volume (ECV) and indexed ECV were similar between groups. The 30-day and 1-year mortality rates were 14.6% and 43.8%, respectively. The median follow-up was 4.1 (0.3-5.1) years. By multivariate analysis adjusted for FR, only the mean transaortic gradient was an independent predictor of mortality (hazard ratio: 0.923, 95% confidence interval: 0.864-0.986, p = 0.019). A mean transaortic gradient & LE;25 mmHg was associated with higher all-cause mortality rates (log-rank p = 0.038), while there was no difference in mortality regarding FR status (log-rank p = 0.114).ConclusionsIn patients with classical LFLG-AS undergoing SAVR, the mean transaortic gradient was the only independent mortality predictor in patients with LFLG-AS, especially if & LE;25 mmHg. The absence of left ventricular FR had no prognostic impact on long-term outcomes.

    The Clinical Course of Takotsubo Syndrome Diagnosed According to the InterTAK Criteria
    (2020) FUNDÃO, Nelson Henrique Fantin; RIBEIRO, Henrique Barbosa; CAMPOS, Carlos de Magalhães; SELEME, Vinicius Bocchino; SOEIRO, Alexandre de Matos; VIEIRA, Marcelo Luiz Campos; MATHIAS JR, Wilson; HAJJAR, Ludhmilla Abraão; RIBEIRO, Expedito E.; KALIL FILHO, Roberto
    Abstract Background There has been an increase in the number of cases of Takotsubo syndrome (TTS) and of scientific publications on the theme over the last years. However, little is known about the status of this disease in Brazilian hospitals. Objective To assess mortality and major adverse cardiovascular events (MACE) during hospitalization and follow-up of TTS patients seen in a tertiary hospital in Brazil. Methods This was a retrospective, observational study on 48 patients. Clinical data, signs and symptoms, complementary tests, MACE and all-cause mortality were assessed on admission and during follow-up. Kaplan-Meier curves were used for analysis of all-cause mortality and risk for MACE at median follow-up. The 95% confidence interval was also calculated for a significance level of 5%. Results Mean age of patients was 71 years (SD±13 years), and most patients were women (n=41; 85.4%). During hospitalization, four patients (8.3%) died and five (10.4%) developed MACE. At median follow-up of 354.5 days (IQR of 81.5-896.5 days), the risk of all-cause mortality and MACE was 11.1% (95% CI= 1.8-20.3%) and 12.7% (95% CI= 3.3-22.3%), respectively. Conclusion TTS was associated with high morbidity and mortality rates in a tertiary hospital in Brazil, which were comparable to those observed in acute coronary syndrome. Therefore, the severity of TTS should not be underestimated, and new therapeutic strategies are required. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0

    Myocardial Fibrosis in Classical Low-Flow, Low-Gradient Aortic Stenosis Insights From a Cardiovascular Magnetic Resonance Study
    (2019) ROSA, Vitor E. E.; RIBEIRO, Henrique B.; SAMPAIO, Roney O.; MORAIS, Thamara C.; ROSA, Marcela E. E.; PIRES, Lucas J. T.; VIEIRA, Marcelo L. C.; MATHIAS JR., Wilson; ROCHITTE, Carlos E.; SANTIS, Antonio S. A. L. de; FERNANDES, Joao Ricardo C.; ACCORSI, Tarso A. D.; POMERANTZEFF, Pablo M. A.; RODES-CABAU, Josep; PIBAROT, Philippe; TARASOUTCHI, Flavio
    Background: Few data exist on the degree of interstitial myocardial fibrosis in patients with classical low-flow, low-gradient aortic stenosis (LFLG-AS) and its association with left ventricular flow reserve (FR) on dobutamine stress echocardiography. This study sought to evaluate the diffuse interstitial fibrosis measured by T1 mapping cardiac magnetic resonance technique in LFLG-AS patients with and without FR. Methods: Prospective study including 65 consecutive patients (41 LFLG-AS [mean age, 67.1 +/- 8.4 years; 83% men] and 24 high-gradient aortic stenosis used as controls) undergoing dobutamine stress echocardiography to assess FR and cardiac magnetic resonance to determine the extracellular volume (ECV) fraction of the myocardium, indexed ECV (iECV) to body surface area and late gadolinium enhancement. Results: Interstitial myocardial fibrosis measured by iECV was higher in patients with LFLG-AS with and without FR as compared with high-gradient aortic stenosis (35.25 +/- 9.75 versus 32.93 +/- 11.00 versus 21.19 +/- 6.47 mL/m(2), respectively; P<0.001). However, both ECV and iECV levels were similar between LFLG-AS patients with and without FR (P=0.950 and P=0.701, respectively). Also, FR did not correlate significantly with ECV (r=-0.16, P=0.31) or iECV (r=0.11, P=0.51). Late gadolinium enhancement mass was also similar in patients with versus without FR but lower in high-gradient aortic stenosis (13.3 +/- 10.2 versus 10.5 +/- 7.5 versus 4.8 +/- 5.9 g, respectively; P=0.018). Conclusions: Patients with LFLG-AS have higher ECV, iECV, and late gadolinium enhancement mass compared with high-gradient aortic stenosis. Moreover, among patients with LFLG-AS, the degree of myocardial fibrosis was similar in patients with versus those without FR. These findings suggest that diffuse myocardial fibrosis may not be the main factor responsible for the absence of FR in LFLG-AS patients.

    Comparação entre a ecocardiografia 2D e 3D na avaliação do remodelamento reverso após a TRC
    (2011) HOTTA, Viviane Tiemi; MARTINELLI FILHO, Martino; MADY, Charles; MATHIAS JR., Wilson; VIEIRA, Marcelo Luiz Campos
    Background: Echocardiography is a useful method for screening and assessing response to cardiac resynchronization therapy (CRT). 3D echocardiography has already established its role in the evaluation of ventricular volumes and ejection fraction (LVEF) with excellent correlation of results when compared with magnetic resonance imaging (MRI). Objective: To compare the evaluation of ventricular volumes (LVDV, LVSV), LVEF, and LV mass before and after CRT by 2D echocardiography and three-dimensional echocardiography. Methods: We evaluated 24 patients with heart failure (HF), functional class (FC) III or IV (NYHA), sinus rhythm QRS >= 120 ms, during an optimized therapy for HF undergoing CRT. We conducted electrocardiogram (ECG), clinical evaluation, 2D and 3D echocardiography before, three and six months after CRT. The comparison between the techniques was performed using Pearson's correlation (r). Results: At baseline, the correlation between methods was 0.96 for evaluation of LVDV, 0.95 for evaluation of LVSV, 0.87 for LVEF and 0.72 for LV mass. After three months of CRT, the correlation between methods for analysis of LVDV was 0.96, 0.95 for LVSV, 0.95 for LVEF, and 0.77 for LV mass. After six months of CRT, the correlation between 2D and 3D echocardiography for analysis of LVDV was 0.98, 0.91 for LVSV, 0.96 for LVEF, and 0.85 for LV mass. Conclusion: This study reported was a reduction of LVDV, LVSV, besides improvement in LVEF after CRT. There was an excellent correlation between the 2D and 3D echocardiography for evaluation of ventricular volumes and LVEF, and a good correlation between methods for evaluation of left ventricular mass before and after CRT.
