- Transcatheter Valve-in-Valve Procedures for Bioprosthetic Valve Dysfunction in Patients With Rheumatic vs. Non-Rheumatic Valvular Heart Disease(2021) LOPES, Mariana Pezzute; ROSA, Vitor Emer Egypto; PALMA, Jose Honorio; VIEIRA, Marcelo Luiz Campos; FERNANDES, Joao Ricardo Cordeiro; SANTIS, Antonio de; SPINA, Guilherme Sobreira; FONSECA, Rafael de Jesus; MARCHI, Mauricio F. de Sa; ABIZAID, Alexandre; BRITO, Fabio Sandoli de; TARASOUTCHI, Flavio; SAMPAIO, Roney Orismar; RIBEIRO, Henrique BarbosaBackground: Bioprosthetic heart valve has limited durability and lower long-term performance especially in rheumatic heart disease (RHD) patients that are often subject to multiple redo operations. Minimally invasive procedures, such as transcatheter valve-in-valve (ViV) implantation, may offer an attractive alternative, although data is lacking. The aim of this study was to evaluate the baseline characteristics and clinical outcomes in rheumatic vs. non-rheumatic patients undergoing ViV procedures for severe bioprosthetic valve dysfunction. Methods: Single center, prospective study, including consecutive patients undergoing transcatheter ViV implantation in aortic, mitral and tricuspid position, from May 2015 to September 2020. RHD was defined according to clinical history, previous echocardiographic and surgical findings. Results: Among 106 patients included, 69 had rheumatic etiology and 37 were non-rheumatic. Rheumatic patients had higher incidence of female sex (73.9 vs. 43.2%, respectively; p = 0.004), atrial fibrillation (82.6 vs. 45.9%, respectively; p < 0.001), and 2 or more prior surgeries (68.1 vs. 32.4%, respectively; p = 0.001). Although, device success was similar between groups (75.4 vs. 89.2% in rheumatic vs. non-rheumatic, respectively; p = 0.148), there was a trend toward higher 30-day mortality rates in the rheumatic patients (21.7 vs. 5.4%, respectively; p = 0.057). Still, at median followup of 20.7 [5.1-30.4] months, cumulative mortality was similar between both groups (p = 0.779). Conclusion: Transcatheter ViV implantation is an acceptable alternative to redo operations in the treatment of patients with RHD and severe bioprosthetic valve dysfunction. Despite similar device success rates, rheumatic patients present higher 30 day mortality rates with good mid-term clinical outcomes. Future studies with a larger number of patients and follow-up are still warranted, to firmly conclude on the role transcatheter ViV procedures in the RHD population.

B.- Heyde's Syndrome: Therapeutic Strategies and Long-Term Follow-Up(2021) ROSA, Vitor Emer Egypto; RIBEIRO, Henrique Barbosa; FERNANDES, Joao Ricardo Cordeiro; SANTIS, Antonio de; SPINA, Guilherme Sobreira; PAIXAO, Milena Ribeiro; PIRES, Lucas Jose Tachotti; BETTEGA, Marcelo; ACCORSI, Tarso Augusto Duenhas; SAMPAIO, Roney Orismar; TARASOUTCHI, FlavioBackground: Heyde's syndrome is the association of severe aortic stenosis with episodes of gastrointestinal due to angiodysplastic lesion. Little is known about the factors associated with new episodes of bleeding and long-term outcomes. Furthermore, most data are restricted to case reports and small case series. Objective: To assess the clinical, laboratory and echocardiography profile of patients with Heyde's syndrome who underwent valve intervention or drug therapy. Methods: Prospective cohort of 24 consecutive patients from 2005 to 2018. Clinical, laboratory and echocardiography data were assessed, as well as those related to valve intervention and to outcomes after diagnosis. Statistical significance was set p < 0.05. Results: Half of the 24 patients (50%) presented with bleeding requiring blood transfusion on admission. Angiodysplasias were more frequently found in the ascending colon (62%). Valve intervention (surgical or transcatheter) was performed in 70.8% of the patients, and 29.2% remained on drug therapy. News episodes of bleeding occurred in 25% of the cases, and there was no difference between clinical and intervention groups (28.6 vs 23.5%, p = 1.00; respectively). Mortality at 2-year and 5-year follow-up was 16% and 25%, with no difference between the groups (log-rank p = 0.185 and 0.737, respectively). Conclusions: Patients with Heyde's syndrome had a high rate of bleeding requiring blood transfusion on admission, suggesting that is a severe disease with high mortality risk. No difference was found between the groups subjected to clinical treatment and to valve intervention with regard to rates of rebleeding and late mortality.
- Rheumatic Myocarditis: A Poorly Recognized Etiology of Left Ventricular Dysfunction in Valvular Heart Disease Patients(2021) ROSA, Vitor Emer Egypto; LOPES, Mariana Pezzute; SPINA, Guilherme Sobreira; SOARES JUNIOR, Jose; SALAZAR, David; ROMERO, Cristhian Espinoza; LOTTENBERG, Marcos Pita; SANTIS, Antonio de; PIRES, Lucas Jose Neves Tachotti; GONCALVES, Luis Fernando Tonello; FERNANDES, Joao Ricardo Cordeiro; SAMPAIO, Roney Orismar; TARASOUTCHI, FlavioBackground: Heart failure occurs in similar to 10% of patients with acute rheumatic fever (RF), and several studies have shown that cardiac decompensation in RF results primarily from valvular disease and is not due to primary myocarditis. However, the literature on this topic is scarce, and a recent case series has shown that recurrent RF can cause ventricular dysfunction even in the absence of valvular heart disease. Methods: The present study evaluated the clinical, laboratory and imaging characteristics of 25 consecutive patients with a clinical diagnosis of myocarditis confirmed by 18F-FDG PET/CT or gallium-67 cardiac scintigraphy and RF reactivation according to the revised Jones Criteria. Patients underwent three sequential echocardiograms at (1) baseline, (2) during myocarditis and (3) post corticosteroid treatment. Patients were divided according to the presence (Group 1) or absence (Group 2) of reduced left ventricular ejection fraction (LVEF) during myocarditis episodes. Results: The median age was 42 (17-51) years, 64% of patients were older than 40 years, and 64% were women. Between Group 1 (n = 16) and in Group 2 (n = 9), there were no demographic, echocardiographic or laboratory differences except for NYHA III/IV heart failure (Group 1: 100.0% vs. Group 2: 50.0%; p = 0.012) and LVEF (30 [25-37] vs. 56 [49-62]%, respectively; p < 0.001), as expected. Group 1 patients showed a significant reduction in LVEF during carditis with further improvement after treatment. There was no correlation between LVEF and valvular dysfunction during myocarditis. Among all patients, 19 (76%) underwent 18F-FDG PET/CT, with a positive scan in 68.4%, and 21 (84%) underwent gallium-67 cardiac scintigraphy, with positive uptake in 95.2%, there was no difference between these groups. Conclusion: Myocarditis due to rheumatic fever reactivation can cause left ventricular dysfunction despite valvular disease, and it is reversible after corticosteroid treatment.
conferenceObject CARDIOVASCULAR DISEASE IN A PATIENT WITH TAKAYASU'S ARTERITIS AND APOLIPOPROTEIN DEFICIENCY(2021) ZIOTTI, Sara Del Vecchio; PINESI, Henrique Trombini; SPINA, Guilherme Sobreira; GAIOTTO, Fabio; DEMARCHI, Lea Maria Macruz Ferreiraarticle Total surgical correction of Lutembacher syndrome associated with partial anomalous connection of the pulmonary veins and tricuspid regurgitation(2021) POMERANTZEFF, Pablo M. A.; BICHUETTE, Luciana D.; VERONESE, Elinthon T.; RODRIGUES, Renan C.; SPINA, Guilherme S.; JATENE, Fabio B.Lutembacher syndrome is characterized by the association of mitral stenosis and atrial septal defect (ASD), usually of the ostium secundum type. The association between superior vena cava-type ASD and partial anomalous pulmonary venous connection is unusual and there are few descriptions in the literature. We report this condition in a 24-year-old woman who was admitted to the hospital with a 1-year history of progressive dyspnea and describe the successful surgical repair following mitral commissurotomy and tunneling of the anomalous pulmonary veins to the left atrium, which determines the closure of the ASD and tricuspid repair.
