[Clinical and hemodynamic results after aneurysmectomy and coronary revascularization]
Insights
Left ventricular aneurysmectomy (LVA) improves heart function and patient well-being, enhancing ejection fraction and contractility. However, clinical improvements do not directly correlate with hemodynamic changes post-surgery.
Area of Science:
- Cardiology
- Cardiac Surgery
- Cardiovascular Physiology
Context:
- Left ventricular aneurysmectomy (LVA) is a surgical procedure addressing heart damage.
- Assessing the impact of LVA on left ventricular function (LVF) is crucial for patient outcomes.
Purpose:
- To prospectively evaluate the clinical and hemodynamic effects of LVA.
- To determine the correlation between functional improvements and patient status after LVA.
Summary:
- Nineteen patients underwent LVA between 1979 and 1983 with no operative deaths.
- Significant improvements were observed in NYHA class (68%) and ejection fraction (33% to 43%, p<0.001).
- Abnormal left ventricular segments decreased (66% to 57%, p<0.05), with no change in end-diastolic pressure.
Impact:
- LVA demonstrates a positive impact on LVF, including ejection fraction and segmental contractility.
- The procedure leads to improved clinical status in a majority of patients.
- No direct correlation was found between clinical and hemodynamic improvements post-LVA.
Abstract:
To assess the effects of left ventricular aneurysmectomy (l.v.a.) on left ventricular function (l.v.f.), a prospective clinical and hemodynamic study has been performed in nineteen patients (pts) operated on from 1979 to 1983. There where no operative deaths and only one late death during follow-up. A significant improvement in NYHA class was observed in 68% of the pts, 16% worsened, and the clinical status in the remaining 16% was unchanged. Hemodynamic data showed an increase in e.f. (33 +/- 12% to 43 +/- 10%; p less than 0.001), a reduction of the percentage of the abnormally contracting left ventricular segments (66 +/- 23% to 57 +/- 23%; p less than 0.05) and no significant changes of left ventricular end diastolic pressure. Revascularization index (nr. of bypassed vessels/nr. of stenotic vessels) and graft patency rate were low (0.57 and 0.72 respectively). No significant relation was noted between clinical and hemodynamic findings in the postoperative study. We conclude that l.v.a. is associated with an improvement of l.v.f. (mainly in e.f. and segmental wall contractility) and of clinical status of the pts but without a direct relation between these two parameters.
