Propafenone, given before electrical cardioversion for chronic atrial fibrillation does not affect the mean defibrillation threshold or the rate of successful arrhythmia conversion. It decreases the recurrence of atrial fibrillation early after shock, thus allowing more patients to be discharged from the hospital with sinus rhythm.

A case of a giant vegetation of the mitral valve causing sudden death of the patient is reported. The case underlines that urgent removal of a big mass must always be considered because of the risk of sudden death or catastrophic embolism. Echocardiographic differential diagnosis of a mass is discussed and is crucial for the choice of the strategy.
