Brazilian Single-Center Experience with Aortic Root Replacement in 448 Patients...

Abstract Introduction: The objective of this study was to evaluate whether a surgery with the use of valved conduit is capable of leading to better immediate and late results than those obtained by the valve-sparing aortic root reconstruction technique. Methods: Between January 2002 and June 2016, 448 patients underwent aortic root reconstruction. These were divided into three groups according to the technique ...

Galectina-3 em Pacientes com Pericardite Constritiva Crônica

Resumo Fundamento A galectina-3 (Gal-3) é uma molécula pró-inflamatória e pró-fibrótica, envolvida na patogênese da insuficiência cardíaca. O papel da Gal-3 em pacientes com pericardite constritiva crônica (PCC) não está claro. Objetivo O objetivo deste estudo foi avaliar os níveis de Gal-3 em pacientes com PCC e correlacioná-los com parâmetros clínicos, funcionais e histológicos. Métodos Nós avaliamos prospect...

Analysis of >100,000 Cardiovascular Surgeries Performed at the Heart Institu...

Abstract Background: The current challenge of cardiovascular surgery (CVS) is to improve the outcomes in increasingly severe patients. In this respect, continuous quality improvement (CQI) programs have had an impact on outcomes. Objective: To assess the evolution of the incidence and mortality due to CVS, as well as the current outcomes of the Hospital das Clínicas Heart Institute of the University of São Paul...

Use of 3D Printing in Preoperative Planning and Training for Aortic Endovascula...

Abstract Introduction: Three-dimensional (3D) printing has become an affordable tool for assisting heart surgeons in the aorta endovascular field, both in surgical planning, education and training of residents and students. This technique permits the construction of physical prototypes from conventional medical images by converting the anatomical information into computer aided design (CAD) files. Objective: To...

Perioperative Management of the Diabetic Patient Referred to Cardiac Surgery

Abstract Currently there is a progressive increase in the prevalence of diabetes in a referred for cardiovascular surgery. Benefits of glycemic management (< 180 mg/dL) in diabetic patients compared to patients without diabetes in perioperative cardiac surgery. The purpose of this study is to present recommendations based on international evidence and adapted to our clinical practice for the perioperative manag...

Importance of Clinical and Laboratory Findings in the Diagnosis and Surgical Pr...

Abstract Background: International studies have reported the value of the clinical profile and laboratory findings in the diagnosis of constrictive pericarditis. However, Brazilian population data are scarce. Objective: To assess the clinical characteristics, sensitivity of imaging tests and factors related to the death of patients with constrictive pericarditis undergoing pericardiectomy. Methods: Patients wit...

Hybrid Approach of Aortic Diseases: Zone 1 Delivery and Volumetric Analysis on ...

Abstract 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 extens...

Acute Myocardial Infarction and Severe Prosthetic Dysfunction after Bentall Pro...

Surgical treatment of complex aneurysms and thoracic aortic dissections with th...

AbstractObjective:Report initial experience with the Frozen Elephant Trunk technique.Methods:From July 2009 to October 2013, Frozen Elephant Trunk technique was performed in 21 patients (66% male, mean age 56 ±11 years). They had type A aortic dissection (acute 9.6%, chronic 57.3%), type B (14.3%, all chronic) and complex aneurysms (19%). It was 9.5% of reoperations and 38% of associated procedures (25.3% mioca...

Surgery of the aortic root: should we go for the valve-sparing root reconstruct...

AbstractObjective:To compare the results of the root reconstruction with the aortic valve-sparing operation versus composite graftvalve 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 fu...
