We investigate the usefulness of minimally invasive aortic valve replacement (MICS-AVR) which was performed in our hospital. Methods: Of 63 consecutive patients undergone an isolated aortic valve replacement (AVR), 16 patients underwent MICS-AVR with partial lower sternotomy (M group) and 47 patients underwent AVR with median full sternotomy (C group). We compared the two groups in a retrospective study. Results: No significant difference was found in the surgical and perioperative-related factors between the two groups. However, the average of aortic cross-clamping time was longer, and intensive and high care unit stay was shorter in the M group. A tendency to decrease blood transfusion was observed in the M group. There was no hospital death in all patients. The mean follow-up period was 29 ± 15 months. There was no significant difference between the two groups in the survival rate, and the 5-year survival rates were 88.9% in the M group and 85.9% in the C group. Conclusion: It was suggested that the MICS-AVR could be safe and useful procedure in AVR.展开更多

We describe a case of idiopathic DCM that underwent successful surgical treatment using a modified left ventriculectomy, modification of the Batista procedure. The patient was a 63-year-old man who suffered from heart failure, New York Heart Association (NYHA) Class IV. Heart failure was derived from idiopathic DCM with a severely compromised left ventricular function complicated by left ventricular thrombosis. He underwent successful surgical treatment, specifically partial left ventriculectomy combined with the papillary muscle approximation, and the postoperative course was uneventful. He has been well with NYHA Class I for 3 years after the operation without heart failure.展开更多
