Serial evaluation of cardiac function with aortic regurgitation caused by serious aortic lesions. A preliminary
1Second Department of Surgery, Okayama University Medical School, Japan.
Insights
Patients with aortic regurgitation and serious aortic lesions show better postoperative recovery and preserved left ventricular (LV) function after simultaneous correction. This supports combined surgical repair for improved outcomes.
Area of Science:
- Cardiology
- Cardiac Surgery
- Cardiovascular Physiology
Background:
- Aortic regurgitation (AR) with concurrent serious aortic lesions presents complex clinical challenges.
- Understanding the impact of combined lesions on left ventricular (LV) function is crucial for surgical planning.
Purpose of the Study:
- To compare the postoperative recovery and LV function between patients with AR due to serious aortic lesions (AR-Ao-group) and isolated chronic AR (AR-group).
- To evaluate the efficacy of simultaneous correction of aortic incompetence and aortic lesions.
Main Methods:
- Serial evaluation of LV function and LV sphericity before and after surgery.
- Comparison of outcomes between ten cases in the AR-Ao-group and the AR-group.
Main Results:
- No significant preoperative LV function differences were observed between the groups.
- Statistically significant improvements in LV sphericity and LV function were noted postoperatively in the AR-Ao-group.
- Adequate LV function reserve was maintained in the AR-Ao-group.
Conclusions:
- Simultaneous correction of aortic incompetence and aortic lesions leads to superior postoperative outcomes.
- The AR-Ao-group demonstrated better LV functional recovery compared to the AR-group.
- Combined surgical repair is recommended for patients with AR and associated aortic lesions.
Abstract:
Clinical and hemodynamic appearances of aortic regurgitation caused by serious aortic lesions (AR-Ao-group) seemed more deteriorated than those with isolated chronic aortic regurgitation (AR-group). Often postoperative course and operative outcome are smooth and satisfactory in the AR-Ao-group. To support this observation, serial changes of left ventricular (LV) function and LV sphericity were evaluated before and after operation in ten cases in the AR-Ao-group and compared with those in the AR-group. Before operation, there were no significant differences in LV function between the two groups. Postoperative improvement of LV sphericity and LV function were statistically better in the AR-Ao-group. The LV function reserve was considered sufficiently retained in the AR-Ao-group. Results with this study supported that clinical observation. Therefore, the total correction, at the same time of aortic incompetence and aortic lesions is recommended.
