ABSTRACT

OBJECTIVES: The aim of this study is the assessment of immediate clinical and angiographic results and medium- to long-term clinical follow-up after Bard-XT (Bard, Billerica, Massachusetts) coronary stent deployment. METHODS: The implantation of 196 stents of various lengths (11, 15 and 19 mm) was attempted in 181 patients (70.1% male) from January 1997 to January 1998. Lesions were type A in 5.6% of the cases, type B1 in 44.4%, type B2 in 45.9% and type C in 4.1%. Implantation of the stent was elective in 53.6% and for bail-out situations in 46.4% of the lesions. RESULTS: The immediate angiographic success rate was 98.5% and the immediate clinical success rate (angiographic success with no major complications during in-hospital stay) was 96.9%. The minimal lumen diameter increased from 0.82 +/- 0.6 mm to 3.0 +/- 0.71 mm after intervention, relative to an immediate post-procedural residual stenosis of 3.05 +/- 9.12%. During the mean in-hospital stay of 2.6 +/- 1.9 days, 3.8% of the patients had a minor clinical event, and 1.5% had a major clinical event. During late follow-up, 3.9% of the patients died. Clinical follow-up of 89.5% of the eligible patients after 241.1 +/- 73.9 days showed that 80.6% of them had negative stress tests, thus reaching a clinical restenosis rate of 19.4%. In a multivariate analysis, only systemic arterial hypertension (p = 0.0012) and a previous history of myocardial infarction (p = 0.02) had a positive correlation with clinical restenosis. CONCLUSIONS: The preliminary experience with the Bard-XT coronary stent was associated with good immediate and medium- to long-term clinical outcome. The results were comparable to those obtained with slotted-tube stents.

ABSTRACT

A case of a 62-year-old patient with Ebstein's anomaly is presented. Despite the severe anatomical abnormalities, he was asymptomatic until 61 years of age. Anatomic aspects, clinical features and the diagnostic techniques used are analyzed.
