Dysfunction of the Björk-Shiley prosthesis. Report of 32 cases.

We present 32 cases of dysfunction of the Björk-Shiley valvular prosthesis, representing 3.01% of the 1,063 BS prostheses implanted at this clinic. The complications observed were thrombosis of the prosthesis, suture dehiscence with or without endocarditis and disc-suture interference. In selected, favourable cases, we prefer thrombectomy with generous washing of the prosthesis and rotation of the disc, without removal of the disc from the prosthesis. Furthermore, when the dehiscence does not exceed 1/3 of the circumference of the ring, we have achieved very good results with single sutures supported on Teflon patches. Subsequent failures of this procedure were not of a technique nature, but rather due to the poor condition of the patients. In situations of clinical emergency, the diagnosis of valvular dysfunction may suffice as indication of surgery, further diagnostic measures being postponed in view of the data of the physical exploration.

Thrombectomy: surgical treatment of the thrombosed Björk-Shiley prosthesis. Report of seven cases and review of the literature.

Among 1,000 patients with 1,225 Björk-Shiley prostheses, we have detected 12 cases (0.98%) of late thrombosis of the Prosthesis, seven of which were successfully managed by thrombectomy. A review of other authors' experience with this procedure shows no deaths directly attributable to thrombectomy, although two patients had cerebral embolization during the procedure. For prevention of this complication, we propose that both the aorta and the left atrium be explored during thrombectomy of either the mitral or the aortic prosthesis so as to achieve complete exposure of the left ventricular outflow tract and complete removal of any thrombus located in the ventricle. We consider this the procedure of tract and complete removal of any thrombus located in the ventricle. We consider this the procedure of choice in thrombosis of the Björk-Shiley prosthesis. Replacement of the prosthesis would then be restricted to cases of prosthesis damage or those in which adequate anticoagulation cannot be maintained.

Iatrogenic myocardial dysfunction after formalization of the heart.

A 20-year-old patient with myoepicardial echinococcosis was referred to our hospital for surgical treatment. After polycystectomy had been performed, the surgical area was mistakenly washed with formaldehyde solution, and severe myocardial dysfunction ensued. Histological alterations were compatible with toxic cellular damage.
