Coarctation of the aorta and severe aortic insufficiency: What to repair first?

A new surgical approach is proposed for patients with coarctation of the aorta associated with severe aortic valvular insufficiency. The valvular lesion should be repaired first and the coarctation corrected during a second operation; both interventions should be done during the same hospital stay. We base our approach on the belief that improved coronary perfusion can be achieved when the aortic insufficiency is corrected first. The disadvantages of the opposite surgical approach, such as anticoagulation problems, renal underperfusion, and hypertensive complications are easily avoided.

Reoperation for dysfunction of the Björk-Shiley mitral disc prosthesis: report of eight cases.

Of 193 patients with Björk-Shiley mitral valve prostheses, replacement was necessary in 8 (4.1%). The reasons for reoperation were: detachment (4), thrombosis (1), technical error (1), and late disc entrapment (2). Five of these patients died (62.5%), the death being directly related to the need for urgent operation because of low cardiac output. We recommend avoiding the use of the larger sized Björk-Shiley prostheses, since striking of the disc against the ventricle wall, probably consequent to postoperative decrease in heart size, may appear even 1 year after implantation of the prosthesis. An early diagnosis and early reoperation offer these patients a much more favorable prognosis.

Cardiac valve replacement with the Björk-Shiley prosthesis in young patients.

Between 1971 and 1974, 26 valve replacements with the Björk-Shiley tilting disc valve prosthesis were performed in 23 children between 4 and 16 years of age. Mitral valve replacement was carried out in 11 patients, aortic valve replacement in 9 and double replacement in the other 3 patients. Several of the patients presented associated lesions which were also corrected at the same intervention, One patient died during the postoperative period; the remaining 22 all showed significant clinical remission. No incidents of thromboembolism or complications of any other nature were observed during follow-up periods of 6 to 26 months. It is our belief that the Björk-Shiley valve represents an improvement over other prostheses currently used for the surgical correction of valve disease in children.

Unusual complication of the Sengstaken-Blakemore tube.

Reported here is the first description of innominate vein obstruction by esophageal tamponade. The syndrome is characterized by local edema of the area drained by the vein. The diagnosis can be made by phlebography. Deflation of the balloon corrects the problem.

[Experimental cardiogenic shock (author's transl)].

An experimental model fo cardiogenic shock has been developed in anesthetized dogs. The shock was produced by injecting mercury into the second diagonal branch of the descending anterior coronary artery. Arterial and venous pressure E.C.G., aortic, renal and circumflex flow were directly measured. Other parameters such as O2 consumption and arterio-venous difference were also studied. The present model seems very useful to make therapeutic studies. Open chest surgery has been used for simplicity and economic reasons.

Cardiac echinococcosis: report of 3 cases and review of the literature.

Three patients who underwent successful surgical treatment of cardiac hydatid disease are discussed. The nonspecificity of diagnostic measures and the importance of keeping this diagnosis in mind when faced with a patient coming from an area where hydatidosis is endemic are stressed. We propose the use of cardiopulmonary bypass in the surgical treatment of this problem.

Combined mitral and aortic valve replacement with the Börk-Shiley prosthesis.

Combined mitral and aortic valve replacement with the BJORK-Shiley tilting-disc valve prosthesis was performed in 42 patients. Hospital and late mortality rates were both at the 9.5% level. No correlation was seen between mortality and combination of concomitant valve lesions. Morbidity was elevated. No episodes of embolism were observed after surgery, although one patient died of severe haemorrhage. Only one patient showed valvular dysfunction (grade 2/4 leakage), but did not require reoperation. Postoperatively, 75.7% of the patients were asymptomatic for a mean follow-up period of 21.1 months. The Björk-Shiley prosthesis offers a small gradient associated with a low profile, which constitute important advantages in multiple valve replacement.
