P-wave durations as a predictor for atrial fibrillation development in patients with hypertrophic cardiomyopathy.

Atrial fibrillation (AF) is the most common arrhythmia observed in hypertropic cardiomyopathy (HCM) and is associated with an acute deterioration. Recently, P wave dispersion (PWD) reflecting inhomogeneous atrial conduction has been proposed as being useful for the estimation of paroxysmal AF. In this study, we aimed to define the clinical, echocardiographic and electrocardiographic predictors for AF occurrence in patients with HCM.

Elliptical rotation flap for pilonidal sinus.

Background: The treatment of the symptomatic pilonidal sinus is surgical with one of the most extensive being excision of the diseased tissue down to the sacral fascia. The closure of the defect is the matter of debate. An elliptical rotation flap has been used for pilonidal sinus treatment with no recurrence rate.
