Aortic valve replacement and repair of left ventricular pseudoaneurysm in a Jehovah's Witness.

The preoperative and surgical management of a giant left ventricular pseudoaneurysm(LVP) associated with aortic valve replacement in a 76 year old male Jehovah's Witness patient is reported. The satisfactory recovery observed in this patient demonstrates the feasibility of this complex surgical procedure even in this particular patient population.

P wave duration and morphology predict atrial fibrillation recurrence in patients with sinus node dysfunction and atrial-based pacemaker.

P wave duration and morphology have never been systematically evaluated as markers of AF in patients with a conventional indication to pacing. This study correlated sinus P wave duration and morphology and the incidence of AF in patients with sinus node dysfunction (SND), previous history of AF before implant, and atrial-based pacemaker. Included were 140 patients (86 men, 54 women; mean age 71.
