[Aortocoronary bypass surgery at Tygerberg Hospital, 1978 - 1980]
Insights
Saphenous vein bypass surgery for coronary artery disease showed low operative mortality and excellent long-term outcomes. Most patients experienced relief from angina, resuming normal activities post-surgery.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Outcomes
- Coronary Artery Disease Management
Context:
- Study conducted at Tygerberg Hospital between January 1978 and December 1980.
- 118 patients underwent saphenous vein bypass surgery for obstructive coronary artery disease.
- 16 patients had additional procedures like valve replacement or aneurysm resection.
Purpose:
- To evaluate the operative and long-term outcomes of saphenous vein bypass surgery for coronary artery disease.
- To assess the mortality rates and incidence of major cardiac events post-surgery.
- To determine the impact of surgery on patients' quality of life, including angina relief and return to work.
Summary:
- Operative and hospital mortality was low at 3.0% overall and 3.3% for isolated bypass surgery.
- Follow-up of surviving patients (mean 16.4 months) showed a low incidence of late myocardial infarction (3.6%).
- 89.1% of patients were free of angina pectoris, with most resuming normal activities or retirement.
Impact:
- Demonstrates the efficacy and safety of saphenous vein bypass surgery in managing coronary artery disease.
- Highlights the significant improvement in patient quality of life and functional status post-intervention.
- Provides valuable data on long-term outcomes, informing clinical practice for cardiac surgery.
Abstract:
Between January 1978 and December 1980. 118 patients underwent saphenous vein bypass surgery for obstructive coronary artery disease at Tygerberg Hospital. Sixteen patients in addition to bypass surgery underwent mitral and/or aortic valve replacement or resection of a ventricular aneurysm. The operative and hospital mortality was 3,0% (4/134) for all patients and 3,3% (4/118) for patients who had aortocoronary bypass surgery as the sole procedure. Follow-up of the surviving patients for a mean period of 16,4 months revealed a low incidence of late myocardial infarction of 3.6% (4/112) resulting in the death of only 1 patient; 89.1% of patients were free of angina pectoris and the majority of these resumed their normal work or enjoyed their retirement.
