The Role of Left Ventricular Reconstruction in Ischemic Cardiomyopathy

We review the relevant literature and our own experience to identify cases in which left ventricular reconstruction (LVR) has been successful, particularly for ischemic cardiomyopathy (ICM). Despite substantial advances in medical and device therapies, surgical treatment of ICM remains important. In this context, LVR for ICM is expected to play a complementary role between heart transplantation or ventricular assist device therapy and surgical treatments such as coronary artery bypass surgery. However, the number of LVRs performed has decreased. This may be because of the lack of well-established cases of successful LVR. Although a good outcome can be expected if the left ventricular (LV) volume is controlled after LVR, it is difficult to identify surgical responders based on preoperative LV volume. Here, we focused on the LV diastolic function, assessed by the echocardiographic mitral inflow waveform ratio (E/A ratio), as an index of the degree of progression of LV remodeling and examined the outcomes of LVR. The preserved LV diastolic function group (E/A ratio < 2) had significantly better outcomes than the impaired LV diastolic function group. The relationship between the degree of LV diastolic function and the efficacy of LVR has recently been investigated. Additionally, LVR has evolved from the resection of ventricular aneurysms to the isolation of the infarct area, reduction of LV volume, and restoration of the normal conical structure of the left ventricle, with promising results. Therefore, selective LVR is an option for HF treatment of heart failure.

Background
The anomalous origin of the left circumflex coronary artery is rare and, when isolated, typically has minimal pathological significance. However, it can cause damage or compression of the coronary artery during aortic and mitral valve surgery.
Case presentation
The patient was a 34-year-old male diagnosed with severe aortic regurgitation due to a bicuspid aortic valve following infective endocarditis at the mitral valve. He was referred to our hospital owing to worsening heart failure. Preoperative evaluation revealed a mitral valve aneurysm and an anomalous left circumflex coronary artery originating from the right coronary artery and running posteriorly along the aortic valve annulus. During surgery, dissection of the anomalous left circumflex coronary artery was challenging. Mitral valve aneurysm repair and aortic valve replacement were performed. For the aortic valve replacement, a 23-mm St. Jude Medical Regent valve, one size smaller than optimal, was secured in the supra-annular position. Additionally, a coronary artery bypass graft was performed on the distal circumflex artery using a saphenous vein graft. The patient experienced no ischemic myocardial damage and was discharged in stable condition on postoperative day 14.
Conclusions
The anomalous origin of the left circumflex coronary artery should be recognized, and appropriate measures must be taken during valve surgery. Preemptive coronary artery bypass grafting is a reasonable option for patients undergoing aortic and mitral valve surgeries. -
