The Development of a New Blood Supply to the Heart by Operation*

Myocardial revascularization in the XXI century

“…These methods were all indirect and ineffective. Among them, the one proposed by Beck et al [5] at the Cleveland Clinic in 1935, which sought to obtain collateral circulation with the involvement of structures such as pericardial fat, pectoral muscle or omentum on the chiseling epicardium.…”

Treatment of Coronary Artery Bypass Graft Failure

“…A pioneer in this field is Beck, a surgeon who in 1935 developed an indirect technique of myocardial revascularization by grafting a flap of the pectoralis muscle over the exposed epicardium to create new blood supply. [1] Later, Beck also developed another revascularization technique by anastomosis between the aorta and the coronary sinus. [2] In 1946, the Vineberg procedure was introduced in which the internal mammary artery (IMA) was used to implant directly into the left ventricular and is hence considered the forerunner of coronary artery bypass grafting (CABG).…”

Revascularização transmiocárdica a laser

“…Métodos de revascularização indireta do miocárdio, objetivando melhorar a perfusão do músculo cardíaco através da via extracoronariana, já foram utilizados há muitos anos, antes mesmo do advento da cinecoronariografia, como a escarificação epicár-dica, a talcagem pericárdica, a omentopexia (15) e a acupuntura miocárdica (16). O implante de artéria torácica interna, proposta por VINEBERG (17) teve seus resultados comprovados pela injeção de contraste nas artérias implantadas, mostrando, em vá-rios pacientes, a sua conexão através dos sinusóides miocárdicos (descritos por WEARN et aI.…”
