摘要:

In recent years the development of modern direct techniques for revascularization surgery has resulted in a multitude of critically ill patients undergoing open heart surgery. To deal with the increasing numbers of patients who both require urgent open heart surgery and present with many complicated patterns of disease, a spectrum of cardiac assist measures, ranging from simple pharmacological interventions to mechanical cardiac assist techniques, has been developed. Those temporary mechanical cardiac assist devices which employ the principle of counterpulsation and balloon pumping have met with the most consistent clinical success. We now report our experience and progress in this field since early 1972.

摘要:

Arterial counterpulsation is a major advance in the treatment of myocardial Ischaemla in association with myocardial infarction. Counterpulsation is based on sound physiological principles and can be expected to limit ischaemia and necrosis when applied within the first 12 to 24 hours of infarction. It has been used in massive infarction with cardiogenic shock, and in threatening Infarction. Good results at both ends of a clinical spectrum suggest an important role throughout the spectrum. Studies in progress are attempting to define this role.

摘要:

A series of 84 patients with unstable angina, treated surgically by grafting procedures between October 1970 and September 1976, have been reviewed. The study indicates that extensive coronary artery disease is common in these patients, and suggests that operation may favourably influence mortality, both immediate and delayed, but does not reduce the risk of myocardial infarction. Eighty per cent of the patients were relieved of angina and able to lead a reasonably normal existence.

摘要:

This paper considers the changing concepts in management, and the results of surgery in 1000 isolated procedures on the mitral valve, during the past 25 years.The first 251 patients were managed by closed methods with an operative mortality of 4%, but with a high reoperation rate, at least 44% ultimately having valve replacement. Open methods were first used in 1960, 17 patients having conservative valvotomy without mortality, but with indifferent results. Valve replacement began in March, 1963, and since that time 615 mitral valve replacements have been carried out, in 433 of which it was an isolated procedure. The first 290 patients had replacement with a Starr Edwards ball valve prosthesis. The actuarial curve shows a survival rate of 70% at 5 years, 61% at 8 years and probably 50% at 15 years. The remainder, except for two, had replacement with disc valves, the first 65 with Bjork Shiley, and the last 76 with Lillehei Kaster prostheses. Four patients with Bjork Shiley prostheses developed thrombosis on the prosthesis, and this was a factor influencing the change to a LilleheiKaster prosthesis. The actuarial curve shows a survival rate of 86% at 4 1/2 years. Since March 1963, 171 patients have had conservative procedures with preservation of the valve; in 57 it was a blind procedure and in 114 it was an open procedure. There were no early deaths in these 171 patients, but there have been four late deaths. Twenty later came to valve replacement, 12 (20%) of them being in the closed gr'oup and 8 (7%) in the open group. One hundred and twenty‐eight (74%) are considered to be Grade I or II, most of these being in the open grou

摘要:

A retrospective study of the results of surgical treatment in 124 cases of coarctation of the thoracic aorta is presented. The diagnosis was based on clinical findings alone in 90% of cases. Aortography and/or cardiac catheterization were performed if the diagnosis was in doubt or if other cardiac abnormalities were suspected. Surgical treatment involved either resection with end‐to‐end anastomosis (114) or some form of grafting procedure (10). The results of treatment have been analysed in terms of operative mortality, late mortality, relief of hypertension, and the incidence of re‐ste

摘要:

Eight patients with transient attacks of cerebrovascular insufficiency were treated by reconstruction of an atheromatous stenosis at the origin of a vertebral artery. The technique was relatively simple and safe, and was effective in relieving symptoms. Previous reviews suggest that the symptoms of vertebrobasilar insufficiency tend to be persistent, frequent and distressing, and that they can be a prelude to brain stem infarction. The collateral circulation to the vertebrobasilar system may be restricted by anatomical variations and by disease, particularly affecting the circle of Willis. Bilateral vertebral artery disease can cause appreciable ischæmia even without associated carotid artery disease. Carotid endarterectomy is not particularly effective in relieving vertebrobasilar symptoms. Vertebral artery reconstruction appears to be the appropriate treatment for vertebrobasilar insufficiency
