Article Synopsis
- Catheter ablation for pulmonary vein isolation is a growing treatment for atrial fibrillation, and this study aimed to assess its effects on left atrial volume and pulmonary vein size.
- In a study involving 51 patients, MRI scans showed a 15.7% reduction in left atrial volume and an 11% decrease in the diameter of pulmonary vein ostia after the procedure.
- The results indicate that catheter ablation significantly remodels the left atrium without a high occurrence of severe pulmonary vein stenosis.
Objectives: The purpose of this study was to report the safety, efficacy, and predictors of recurrence of circumferential pulmonary vein (PV) catheter ablation in patients with atrial fibrillation (AF).
Background: Circumferential PV ablation has been described as an alternate ablation strategy for AF.
Methods: Seventy consecutive patients (age 56 +/- 10 years) with symptomatic drug refractory paroxysmal (n = 21), persistent (n = 22), and permanent (n = 27) AF underwent catheter ablation.
Coronary vasospasm and myocardial infarction induced by oral sumatriptan.
Clin Neuropharmacol
November 2004
Coronary vasospasm is well documented as a side effect of injectable subcutaneous forms of sumatriptan; only one such case has been reported so far with oral ingestion of sumatriptan in a patient with underlying coronary artery disease. This report describes a case of coronary vasospasm induced by oral sumatriptan even in normal coronary arteries. Physicians and patients should be aware of a small and unpredictable risk of the serious cardiac side effects of this drug.

Methods And Results: Seventy-five consecutive patients (51 men [68%]; age 54 +/- 13 years) with symptomatic drug-refractory paroxysmal (42 patients), persistent (21 patients), or permanent (12 patients) AF underwent catheter ablation of AF using an irrigated-tip ablation catheter and a standard ablation strategy, which involved electrical isolation of all pulmonary veins (PVs) and creation of a cavotricuspid linear lesion.

Paradoxical embolism is an uncommon but clinically important phenomenon. Elements of diagnosis include the presence of: (1) a venous thrombus, (2) an arterial embolus, (3) a communication between the right and left heart, and (4) a thrombus traversing such a communication. Unfortunately, all of these elements can be rarely demonstrated in each case but the probability should be considered in any patient with 2 or more present.
