RESUMO
We report the use of excimer-laser angioplasty for the treatment of Wiktor and Gianturco-Roubin in-stent restenosis of in two patients. Case 1-a 48-year-old man presented unstable angina five months after Wiktor stent was deployed in right coronary artery. Cardiac catheterization revealed stenosis (95) within the stent. Case 2-a 65-year-old man presented stable angina four months after Gianturco-Roubin stent was deployed in left anterior descending artery. Cardiac catheterization revealed stenosis (80) within the stent. Excimer-laser angioplasty within the stent reduced the stenosis to 19and 30, respectively. The patients recovered and currently, six months post-procedure, are free of chest pain, and cardiac catheterization revealed stenosis to 30and 35, respectively, within the stent. Therefore, the procedure was an effective means of treating restenosis after coronary stent placement, and a prospective comparison of excimer-laser angioplasty and other management alternatives to in-stent restenosis is needed.

PURPOSE: To evaluate the immediate and long term results of percutaneous transluminal coronary balloon angioplasty (PTCA) in patients over 80 years old. METHODS: From 1/1/89 to 6/31/95, 97 patients with 80 years of age or older were submitted to PTCA and were divided into three groups: group A (GrA)-30 patients with stable angina, mean age of 82.5 years, 24 (80) men; group B(GrB)-40 patients with unstable angina, mean age 81.2 years, 31 (77.5) men; group C (GrC)-27 patients with myocardial infarction (MI), mean age of 82 years, 16 (59.2) men. RESULTS: Early outcome-general success rate of 84.5 and mortality rate of 5.1. The success and mortality rate were in GrA 83.3 and 3.3, in GrB 85 and 5 and in GrC 85.2 and 7.4, respectively. Late outcome-the number and percentage of patients with late follow-up and the clinic-angiographic and angiographic restenosis rates were for GrA 19(76), 52.9, 75; GrB 30(88.2), 30.8, 61.5 and GrC 12(52.2), 66.6, 85.7, respectively. CONCLUSION: PTCA can be considered an important revascularization alternative in octogenarian patients because of high early success rate, low mortality and acceptable long-term outcome.

Endomiocardiofibrose é uma doença cardíaca endêmica caracterizada pela presença de tecido fibroso no endocárdio, eventualmente se estendendo para o miocáardio.CAlcificaçäo endocárdica maciça de ventrículo esquerdo é um achado raro, com poucos casos descritos na literatura.Relatamos o primeiro caso, de nosso conhecimento, de calcificaçäo endocárdica maciça biventricular associada a endomiocardiofibrose em mulher de 22 anos.

The authors describe a rare case of circumflex coronary artery perforation during rotational coronary atherectomy complicated with cardiac tamponade and good outcome. The possible causes of perforation are discussed and the burr oversize (burr/artery ratio was 0.58) was refused. Shortening and artery plicature (accordeon effect) might have been the cause of this event. Quantitative measurement was made in order to strengthen this hypothesis. It is emphasized the importance of selecting lesions that should be submitted to rotational coronary atherectomy
É relatado caso raro de perfuração da artéria circunflexa durante aterectomia rotacional (AR), complicado com tamponamento cardíaco, que evoluiu favoravelmente. São discutidas as prováveis causas, afastando a possibilidade da ocorrência de um superdimensionamento da oliva utilizada (relação de diâmetro oliva-artéria foi de 0,58), e é sugerido o encurtamento e plicatura da artéria (efeito sanfona) como provável causa dessa perfuração. São feitas medidas quantitativas para reforçar essa hipótese, e ressaltam-se os cuidados necessários na escolha das lesões a serem submetidas à ablação com AR
