1. COVID-19 - Endothelial Axis and Coronary Artery Bypass Graft Patency: a Target for Therapeutic Intervention?
Abstract It has been reported that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection induces endothelial inflammation, therefore facilitating the progression of endothelial and vascular dysfunction in coronavirus disease 2019 (COVID-19) patients. Coronary artery bypass grafting (CABG) involves mainly the use of the saphenous vein (SV) an

2. Coronary Artery Dissection in a Patient with Buerger's Disease
Abstract Buerger's disease, vasculitis of small and medium-sized blood vessels, is a non-atherosclerotic and progressive occlusive condition which frequently involves the distal part of the limbs. The occlusion of coronary arteries in Buerger's disease is a rare condition; however, coronary artery dissection has not been reported previously. Therefore, this

3. Análise comparativa da perviedade das artérias torácicas internas direita e esquerda na revascularização da região anterior do coração. Avaliação por angiotomografia no 6º mês de pós-operatório / Comparative analysis of patency of right and left internal mammary artery in the revascularization of left anterior descending and branches. Evaluation by angiography in the sixth month postoperatively
Objetivos: O objetivo deste estudo é analisar a perviedade da artéria torácica interna direita (ATID) pediculada, anteroaórtica em anastomose para a região anterior do coração na cirurgia de revascularização do miocárdio (RM), em relação à artéria torácica interna esquerda (ATIE). Métodos: No período de dezembro de 2008 a dezembro de 2011, 1

4. Estudo prospectivo e randomizado da revascularização do miocárdio minimamente invasiva com dissecção da artéria torácica interna esquerda por videotoracoscopia robótica / Robotic left internal mammary artery harvesting for single vessel minimally invasive coronary bypass: a randomized controlled trial
Objective: The aim of this study was to compare the patency of left internal mammary artery (LIMA) robotically harvested for left anterior descendent (LAD) artery minimally invasive bypass with conventional LIMA to LAD off-pump bypass. Method: From 2007 to 2010, 36 patients were randomized to either LIMA robotically harvested to LAD artery minimally invasive

5. Transforming growth factor-β in graft vessels: histology and immunohistochemistry
OBJECTIVES: The biological functions of transforming growth factor-β signaling that involves Smad proteins have not been previously investigated with respect to coronary artery bypass grafts. The aim of the present study was to observe the immunostaining of proteins that are related to this signaling pathway. METHODS: Fifteen remnants of coronary artery byp

6. Comparative study between composite and independent arterial grafts in myocardial revascularization : blood flow and coronary flow reserve analysis by intravascular Doppler / "Estudo comparativo entre os enxertos arteriais compostos e os enxertos arteriais isolados na revascularização do miocárdio: análise do fluxo sangüíneo e da reserva de fluxo coronariano com Doppler intravascular"
O objetivo é comparar o fluxo sanguíneo total (FS) e a reserva de fluxo coronariano (RFC) aos ramos revascularizados pelas artérias torácica interna esquerda (ATIE) e radial (AR) nos enxertos compostos com os enxertos isolados. Foi realizado um ensaio clínico randomizado de 42 pacientes que foram distribuídos em grupo A ou ATIE e AR composta em Y(n=14)

7. The String Phenomenon: An Important Cause of Internal Mammary Artery Graft Failure
Internal mammary arteries are the grafts of choice for coronary artery bypass because they are generally free of atherosclerosis and they have high patency rates as grafts. There are, however, increasing reports of graft failure due to diffuse or distal narrowing, known as the string phenomenon.

8. The internal thoracic (mammary) nerve
The internal thoracic (mammary) nerve is formed by contributions from the subclavian plexus and the phrenic nerve. It descends along the internal thoracic artery to the level of the seventh costal cartilage where it is lost. Some of its branches communicate with the intercostal nerves and are thought to be distributed with these nerves. Others follow perfora

9. Improvement in exertional left ventricular dysfunction after revascularization.
The case is reported of a 63-year-old white man with mild angina pectoris, whose systolic pressure fell 30 mmHg (4-0 kPa) with maximal exercise, without chest pain but with accompanying dizziness. Grafting the internal mammary arteries into the mid left anterior descending and obtuse marginal arteries improved regional myocardial perfusion and increased maxi

10. Late patency of recycled internal mammary artery: verification by Doppler echocardiography and coronary angiography.
We report the case of a 57-year-old man who had presented with exertional angina early in 1997 and had subsequently undergone myocardial revascularization with the use of both internal mammary arteries. Two months after surgery, the patient was readmitted to the hospital with unstable angina. Coronary angiography revealed a 90% occlusion of the left internal

11. Coronary artery bypass surgery: current practice in the United Kingdom.
OBJECTIVE--To assess current clinical practice in coronary artery bypass surgery and compare it with a previous survey conducted five years ago. SETTING--United Kingdom. DESIGN--Postal questionnaires were sent in March 1993 to 120 consultant cardiac surgeons currently performing coronary artery bypass surgery. 104 (87%) were returned by May 1993. RESULTS--Th

12. Blood flow in the internal mammary artery after the administration of papaverine during coronary artery bypass grafting.
Between January 1993 and February 1994, 106 patients whose internal mammary arteries were to be used for revascularization to treat coronary artery disease were examined for a prospective study of papaverine administration. The mean blood flow in the internal mammary artery was 59.9 mL/min +/- 7.3 mL/min before papaverine administration. The patients were di
