Spontaneous inversion of the left atrial appendage.
An interesting case of spontaneous inversion of the left atrial appendage was caused by an acute decrease in ventricular volume and the shortening of diastole during supraventricular tachycardia, creating a negative pressure invaginating the left atrial appendage. The return of normal in sinus rhythm and left-sided diastolic pressures reversed the left atrial appendage to a normal position, sparing the patient unnecessary surgery.
