ABSTRACT: To compare the outcome of 3 months versus 18 months of amiodarone treatment after atrial fibrillation (AF) conversion in patients who experienced the first episode of persistent AF.
We included 51 patients who experienced the first episode of persistent AF receiving amiodarone (600 mg) daily for 4-6 weeks. If AF persisted, electrical cardioversion (ECV) was performed. All patients received amiodarone (200 mg daily) for 3 months and then were randomized to amiodarone (Group I) or placebo (Group II) and followed for 15 months. The control group comprised 9 untreated patients undergoing ECV. Treatment effectiveness was evaluated using a Bayesian model.
Eighteen months after AF reversion, 22 patients (81.5%) in Group I, 13 patients (54.2%) in Group II, and 1 patient (11.1%) in the control group remained in sinus rhythm. No differences were found between Group I patients who required ECV and Group II patients. Sinus rhythm was preserved in all Group I patients when it was achieved during amiodarone administration. Limiting adverse effects occurred in 3 patients (11.1%) in Group I.
In patients regaining sinus rhythm after the first episode of persistent AF, a 3-month amiodarone treatment after reversion is a reasonable option for rhythm control.

ABSTRACT: Capillary malformation-arteriovenous malformation (CM-AVM) is a recently described autosomal dominant disorder that results from mutations in RASA1. It has been initially described as multiple CMs affecting several members of the same family, associated with fast-flow malformations in at least one family member.
To report and analyze clinical data on 45 patients with CM-AVM assessed at the Department of Pediatric Dermatology, Ramos Mejía Hospital (Buenos Aires, Argentina).
Retrospective clinical review of all the patients clinically diagnosed as having CM-AVM over a period of eight years.
Forty-five patients were recorded (24 females and 21 males). The age ranged from one month to 44 years. In 36 patients, the stains were congenital; progressive acquired lesions were observed in 39. Family history was positive in 32 subjects. Well defined, round to oval, pink-purple or reddish-brown macules were found in all the patients; pinpoint red lesions with a pale halo were found in nine cases. The macules were warmer than normal skin in 15 cases and surrounded by a white halo in 26 cases. Three subjects presented associated overgrowth, lymphatic malformation was present in one case, retinal vascular lesion in one patient, and isolated port wine stain in two cases. Three patients also had infantile hemangioma. We had no cases of fast-flow vascular malformation or combined vascular syndromes.
CM-AVM is a heterogeneous disorder with phenotypic variability, from fast-flow malformation, limb enlargement, or Parkes Weber syndrome to multiple CMs without internal involvement.
