We report the case of an 83-year-old man in whom acute left ventricular failure with ventricular arrhythmic storm developed during a Bentall operation. During re-exploration of the annular and coronary ostial anastomoses, no abnormality was seen, and none of the common sequelae of aortic root replacement was evident. The application of retrograde cardioplegia yielded a Teflon pledget that had migrated into the distal part of the left main stem. The pledget was removed, the anastomoses were reestablished, and the patient recovered uneventfully. This case suggests that left ostial anastomosis re-exploration should be carefully considered when no other cause of coronary insufficiency is obvious, and that retrograde cardioplegia may be useful to detect embolization in the left coronary system.

Abstract
We report the case of an 83-year-old man in whom acute left ventricular failure with ventricular arrhythmic storm developed during a Bentall operation. During re-exploration of the annular and coronary ostial anastomoses, no abnormality was seen, and none of the common sequelae of aortic root replacement was evident. The application of retrograde cardioplegia yielded a Teflon pledget that had migrated into the distal part of the left main stem. The pledget was removed, the anastomoses were reestablished, and the patient recovered uneventfully. This case suggests that left ostial anastomosis re-exploration should be carefully considered when no other cause of coronary insufficiency is obvious, and that retrograde cardioplegia may be useful to detect embolization in the left coronary system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
