RESUMO

Isolation of the pulmonary veins by applying radiofrequency is an effective treatment for atrial fibrillation. One of the potential complications with higher clinical compromise utilizing this invasive technique is the occurrence of stenosis of one or more pulmonary veins. This complication can be treated by angioplasty with or without stent implantation, with an adequate clinical improvement, but with a high rate of restenosis.

RESUMO

El aislamiento de las venas pulmonares mediante la aplicación de radiofrecuencia es un tratamiento efectivo de la fibrilación auricular. Una de las complicaciones potenciales y de mayor compromiso clínico de esta técnica invasiva es la estenosis de una o varias venas pulmonares. Esta complicación puede ser tratada mediante angioplastia con o sin colocación de stent, logrando una adecuada mejoría clínica, aunque con un alto índice de recurrencia por re-estenosis.

RESUMO

With conventional stenting, predilatation frequently induces dissections that require deploying stents longer than originally planned. To assess whether direct stenting is safe and may prevent dissections and reduce the length of stents implanted, we conducted a randomized study comparing direct (n = 73) and conventional (n = 78) stenting. Direct stenting was successful in 89% of cases, 11% crossed over to predilation without complications. Dissections occurred more frequently in conventional stenting group (10.3% vs. 1.4%; P = 0.034), but did not translate to a significant stent length difference (16.31 +/- 7.6 vs. 15.31 +/- 5.5; P = NS). Periprocedure creatine kinase elevation and number of balloons utilized were lower with direct stenting.
