RESUMO
Paciente do sexo masculino, 73 anos, hipertenso, dislipidêmico e ex-tabagista, internado com quadro de infarto agudo do miocárdio sem supradesnivelamento do segmento ST. Cineangiocoronariografia demonstrou ponte miocárdica em artéria descendente anterior, sem lesões obstrutivas em outros territórios da circulação coronária. Em decorrência da elevação de marcadores de necrose miocárdica e do surgimento de supradesnivelamento transitório do segmento ST em parede anterior, na vigência de tratamento clínico otimizado, realizou-se ultrassom intracoronário, que evidenciou lesão ulcerada no território da ponte miocárdica, seguido de angioplastia com implante de stent, com sucesso. A evolução foi satisfatória após o procedimento e o paciente recebeu alta hospitalar.
ABSTRACT
We report the case of a 73-year-old man, with a history of hypertension, dyslipidemia, and previous smoking, admitted with a non-ST segment elevation myocardial infarction. Coronary angiography showed a myocardial bridge in the left anterior descending artery, with no obstructive lesions in other coronary arteries. Because of the raise in serum markers of myocardial necrosis and the development of transient ST segment elevation in the anterior wall, despite optimized medical treatment, we performed intravascular ultrasound, which showed an ulcerated lesion in the myocardial bridge territory, which was followed by a successful coronary angioplasty with stent implantation. The patient had a favorable course and was discharged from the hospital.
