Can spontaneous cure occur for cardiac ailments?

Spontaneous cure can occur rarely in some cardiac ailments:

Small ventricular septal defects (defects in the wall between two lower chambers of the heart) and atrial septal defects (defects in the wall between two lower chambers of the heart) in infants can close spontaneously. A clot in a blood vessel of the heart can get spontaneously recanalized sometimes. An accessory electrical conduction pathway of the heart in WPW syndrome can occasionally get fibrosed and lose conduction.
