    (2017) DUNCAN, Jose Augusto; DIAS, Ricardo Ribeiro; DINATO, Fabricio Jose; FERNANDES, Fabio; RAMIREZ, Felix Jose Alvares; MADY, Charles; JATENE, Fabio Biscegli
    Introduction: Conventional techniques of surgical correction of arch and descending aortic diseases remains as high-risk procedures. Endovascular treatments of abdominal and descending thoracic aorta have lower surgical risk. Evolution of both techniques open debranching of the arch and endovascular approach of the descending aorta - may extend a less invasive endovascular treatment for a more extensive disease with necessity of proximal landing zone in the arch. Objective: To evaluate descending thoracic aortic remodeling by means of volumetric analysis after hybrid approach of aortic arch debranching and stenting the descending aorta. Methods: Retrospective review of seven consecutive patients treated between September 2014 and August 2016 for diseases of proximal descending aorta (aneurysms and dissections) by hybrid approach to deliver the endograft at zone 1. Computed tomography angiography were analyzed using a specific software to calculate descending thoracic aorta volumes pre-and postoperatively. Results: Follow-up was done in 100% of patients with a median time of 321 days (range, 41-625 days). No deaths or permanent neurological complications were observed. There were no endoleaks or stent migrations. Freedom from reintervention was 100% at 300 days and 66% at 600 days. Median volume reduction was of 45.5 cm(3), representing a median volume shrinkage by 9.3%. Conclusion: Hybrid approach of arch and descending thoracic aorta diseases is feasible and leads to a favorable aortic remodeling with significant volume reduction.

    Does aortic valve repair in valve-sparing aortic root reconstruction compromise the longevity of the procedure?
    (2017) DIAS, Ricardo Ribeiro; DUNCAN, Jose Augusto; DINATO, Fabricio Jose de Souza; ARAUJO, Lucas Lacerda; ISSA, Hugo Monteiro Neder; FERNANDES, Fabio; MADY, Charles; JATENE, Fabio Biscegli
    OBJECTIVES: The effect of performing aortic valve repair in combination with valve-sparing operation on the length of time for which patients are free from reoperation is unclear. The objective of this study was to determine if the performance of aortic valve repair during valve-sparing operation modified the freedom from reoperation time. METHODS: From January 2003 to July 2014, 78 patients with a mean age of 49 +/- 15 years underwent valve-sparing operation. Sixty-eight percent of these patients were male. Twenty-two (28%) aortic valve repair procedures were performed in this patient population. In the aortic valve repair + valve-sparing operation group, 77.3% of patients had moderate/severe aortic insufficiency, while in the valve-sparing operation group, 58.6% of patients had moderate/severe aortic insufficiency (ns = not significant). Additionally, 13.6% of patients in the aortic valve repair + valve-sparing operation group had functional class III/IV, while 14.2% of patients in the valve-sparing operation group had functional class III/IV (ns). RESULTS: The in-hospital and late mortality rates, for the aortic valve repair + valve-sparing operation and valve-sparing operation groups were similar, as they were 4.5% and 3.6%; and 0% and 1.8%, respectively. In the aortic valve repair + valve-sparing operation group, 0% of patients presented moderate/severe aortic insufficiency during late follow-up, while in the valve-sparing operation group, 14.2% of patients presented with moderate/severe aortic insufficiency during this period (ns). In the aortic valve repair + valve-sparing operation group, 5.3% of patients presented with functional class III/IV, while in the valve-sparing operation group, 4.2% of patients presented with functional class III/IV (ns). In the aortic valve repair + valve-sparing operation group, 0% of patients required reoperation, while in the valve-sparing operation group, 3.6% of patients required reoperation over a mean follow-up period of 1621 +/- 1156 days (75 patients). CONCLUSION: Valve-sparing operation is a safe and long-lasting procedure and performance of aortic valve repair when necessary does not increase risk of reoperation on the aortic valve.

    Surgery of the aortic root: should we go for the valve-sparing root reconstruction or the composite graft-valve replacement is still the first choice of treatment for these patients?
    (2015) LAMANA, Fernando de Azevedo; DIAS, Ricardo Ribeiro; DUNCAN, Jose Augusto; FARIA, Leandro Batisti de; MALBOUISSON, Luiz Marcelo Sa; BORGES, Luciano de Figueiredo; MADY, Charles; JATENE, Fabio Biscegli
    Objective: To compare the results of the root reconstruction with the aortic valve-sparing operation versus composite graft-valve replacement. Methods: From January 2002 to October 2013, 324 patients underwent aortic root reconstruction. They were 263 composite graft-valve replacement and 61 aortic valve-sparing operation (43 reimplantation and 18 remodeling). Twenty-six percent of the patients were NYHA functional class III and IV; 9.6% had Marfan syndrome, and 12% had bicuspid aortic valve. There was a predominance of aneurysms over dissections (81% vs. 19%), with 7% being acute dissections. The complete follow-up of 100% of the patients was performed with median follow-up time of 902 days for patients undergoing composite graft-valve replacement and 1492 for those undergoing aortic valve-sparing operation. Results: In-hospital mortality was 6.7% and 4.9%, respectively for composite graft-valve replacement and aortic valve-sparing operation (ns). During the late follow-up period, there was 0% moderate and 15.4% severe aortic regurgitation, and NYHA functional class I and II were 89.4% and 94%, respectively for composite graft-valve replacement and aortic valve-sparing operation (ns). Root reconstruction with aortic valve-sparing operation showed lower late mortality (P=0.001) and lower bleeding complications (P=0.006). There was no difference for thromboembolism, endocarditis, and need of reoperation. Conclusion: The aortic root reconstruction with preservation of the valve should be the operation being performed for presenting lower late mortality and survival free of bleeding events.

    (2014) AZEREDO, Lisandro Goncalves; VERONESE, Elinthon Tavares; SANTIAGO, Jose Augusto Duncan; BRANDAO, Carlos Manuel de Almeida; POMERANTZEFF, Pablo Maria Alberto; JATENE, Fabio Biscegli
    Objective: Aortic valve replacement with Braile bovine pericardial prosthesis has been routinely done at the Heart Institute of the Universidade de Sao Paulo Medical School since 2006. The objective of this study is to analyze the results of Braile Biomedica (R) aortic bioprosthesis in patients with aortic valve disease. Methods: We retrospectively evaluated 196 patients with aortic valve disease submitted to aortic valve replacement with Braile Biomedica (R) bovine pericardial prosthesis, between 2006 and 2010. Mean age was 59.41 +/- 16.34 years and 67.3% were male. Before surgery, 73.4% of patients were in NYHA functional class III or IV. Results: Hospital mortality was 8.16% (16 patients). Linearized rates of mortality, endocarditis, reintervention, and structural dysfunction were 1.065%, 0.91%, 0.68% and 0.075% patients/year, respectively. Actuarial survival was 90.59 +/- 2.56% in 88 months. Freedom from reintervention, endocarditis and structural dysfunction was respectively 91.38 +/- 2.79%, 89.84 +/- 2.92% and 98.57 +/- 0.72% in 88 months. Conclusion: The Braile Biomedica (R) pericardial aortic valve prosthesis demonstrated actuarial survival and durability similar to that described in the literature, but further follow up is required to assess the incidence of prosthetic valve endocarditis and structural dysfunction in the future.

    Impact of Aortic Valve Function and the Need for Aortic Valve Repair on Long-Term Outcomes of Valve-Sparing Aortic Root Replacement: 13-Year Experience of David Operation
    (2021) CARDOSO, Lucas Figueredo; DIAS, Ricardo Ribeiro; DINATO, Fabricio Jose; DUNCAN, Jose Augusto; FERNANDES, Fabio; RAMIRES, Felix Jose Alvarez; MADY, Charles; JATENE, Fabio Biscegli
    Background The best approach for aortic root disease remains controversial. Composite valve-graft conduit (CVG) replacement offers good results at short-term and long-term follow-up; on the other hand, valve-sparing aortic root replacement (VSARR) has proven to be an excellent treatment alternative. This study aimed to analyse the outcomes after VSARR and compare whether preoperative moderate or severe aortic regurgitation (AR) and or the need for aortic valve repair (AVR) during this procedure influenced survival and freedom from reoperation rates. Methods From September 2005 to June 2018, 104 patients underwent VSARR using the reimplantation technique: 64% presented with preoperative moderate or severe AR, concomitant AVR was performed in 43.3%, Marfan syndrome was present in 16.3%, and 12.5% had a bicuspid aortic valve. Complete follow-up was obtained in 91% of the sample, echocardiographic results were available for 86% and the mean follow-up time was 1,893 days. Results In-hospital mortality was 2.9% and one death occurred 42 days after hospital discharge. In the latest echocardiographic assessment, 88.3% presented with mild AR or better. Freedom from reoperation at 8 years was 95.4%. There was no case of endocarditis and one patient had a stroke 2 years after the operation. There were no between-group differences in morbidity, mortality and complications during the follow-up. Conclusion VSARR can be performed with low mortality rates and reasonable durability of the aortic valve. Neither moderate or severe AR nor the need for aortic valve repair during the procedure altered survival and freedom from reoperation.
