Objective To summarize and analyze the clinical experience in the use of ultrasonic scalpel in skeletonized internal using bilateral sketetonized internal mammary artery harvested by ultrasonic scalpel in Juntendo University Hospital.Results The number of distal anastomoses was(4.1±1.5).Major complieations included severe arrhythmia in 2 patients.cerebral infarction complicated with sepsis in 1,diffuse intraveseular coagulopathy complicated with multiple organ failure in 1 patient.and pneumonia in 2 patients.There were 2 patients dead in-hospital.The mean follow-up period Was(15.6±3.2)months.There Was no late death or cardiac-related events during the follow-up periods.Condusion It is simple and safe to skeletonize the internal mammary artery using the ultrasonic scalpel.The early effect of bilateral skeletonized internal mammary artery grafting was satisfactory.

Objective To evaluate the early and midterm effect by retrospective analysis of the cone reconstruction in Ebstein′s anomaly. Methods From January 2012 through June 2016,16 patients with Ebstein′s anomaly underwent the cone reconstruction in our hospital. There were 7 males and 9 females at mean age(28.21 ± 11.88)years,including 12 patients of Carpentier B type,4 patients of Carpentier C type. There were 9 patients in New York Heart Association(NYHA)functional class Ⅲ,5 patients in NYHA functional class Ⅳand the others in NYHA functional class Ⅱ. All patients had Tricuspid insufficiency ,including 2 patients with Grade 2 ,10 patients with Grade 3 and 4 patients with Grade 4. All patients were followed up over a period of 6 to 51 months (mean:24.36 ± 10.71). By comparing the details of pre-operation with post-operation and post-operation with current stage,we analyze the outcomes of early and midterm effects. Results All patients are well survived. There were one patient recovering from the low cardiac output syndrome with adding the strength of the positive inotropic drug in the first day after operation ,and one patient recovering from bigeminy of ventricular prematurebeat with the aid of amiodarone and lidocaine the third day after operation. The remaining patients recovered smoothly. Early post-operative echocardiograms showed good right ventricular morphology and reduction in tricuspid regurgitation grade from(3.13 ± 0.62)to(1.75 ± 0.45)(P<0.001)with the functional class improved from(3.19 ± 0.66)to(2.00 ± 0.52)(P<0.001). After mean follow-up of(24.36 ± 10.71)months,the situation is improving furtherly with the tricuspid regurgitation grade reducing to(1.31 ± 0.48)(P=0.016)and the functional class rising to(1.50 ± 0.52) (P = 0.031). Conclusions This surgical technique for Ebstein′s anomaly can improve the function of tricuspid valve and the right ventricular morphology. It showed a satisfactory performance in the early and midterm results by enhancing the Cardiac function and life quality. But indications should be strictly grasped and more experiences need to be accumulated. Long-term effect need to be furtherly explored.
