RESUMO
A retrospective analysis of data accumulated over a 21-month period, from December 1989 to September 1991, regarding investigational use of a 308 nanometer Xenon Chloride Excimer Laser Coronary Angioplasty (ELCA) system (Advanced Interventional Systems, Inc., Irvine, CA) was performed. It included a cohort of 131 persons with coronary artery disease who underwent 158 laser angioplasty procedures for attempted treatment of a total of 206 atherosclerotic lesions. Approximately 17% of the lesions treated with ELCA were chronic occlusions, 20% were diffuse lesions greater than 20 mm in length and 30% of the initial ELCA lesions were restenoses of previous balloon-treated sites. Our initial results with ELCA demonstrate similar rates of success, complication, mortality, and restenosis when compared with the larger historical experience with standard coronary balloon technique. In selected subgroups, such as chronically occluded coronary lesions, the acute success rate when using ELCA appears superior to published success rates when similar lesions have been treated with conventional technology.

Coronary spasm and intimal dissection are well-known complications of coronary angioplasty with potentially serious consequences. Their treatments are different and need to be instituted quickly to prevent vessel closure. We report two cases of mechanical deformation caused by the angioplasty hardware masquerading as dissection or spasm during coronary angioplasty of tortuous native right coronary arteries.

A 74-year-old man was admitted to the hospital with congestive heart failure secondary to cor triatriatum. He also had sick sinus syndrome with complete heart block and syncope that had been treated with a permanent pacemaker 20 years earlier. The patient underwent successful surgical resection of the atrial membrane with closure of an atrial septal defect. M-mode, two-dimensional, Doppler, and transesophageal echocardiographic findings are reviewed. A unique "spike and dome" pattern on continuous-wave Doppler echocardiography is described that may suggest diagnosis of cor triatriatum.
