We report a case of coronary encapsulated rupture following stent impl
antation in the distal anastomosis of a saphenous by-pass graft to the
left anterior descending coronary artery that evolved well with conse
rvative treatment. The patient did not require pericardiocentesis and
was treated with prolonged inflations with low pressure autoperfusion
balloon at the rupture point. Pericardial adherences related to a prev
ious coronary surgery probably limited the bleeding process avoiding h
emodynamic collapse.
