We report the Lampshade Technique : a new technique using Carbo-Seal Valsalva (Sorin Biomedica, Saluggia, Italy) to facilitate preparation of a composite graft. A Bentall operation and an ascending aorta replacement were performed with a composite graft using a Carbo-Seal Valsalva. This new technique can be considered useful as it can reduce the time required for preparing a composite graft, and create a skirt portion for continuous suturing to prevent bleeding.

Primary cardiac malignant tumors are relatively rare, and their prognosis is poor. We report a patient with sarcoma causing severe mitral regurgitation and stenosis due to rapid and specific infiltration into the mitral valve.

A 67-year-old man with ascending aortic aneurysm was referred to our hospital. Transthoracic echocardiography showed severe aortic regurgitation with annuloaortic ectasia and transesophageal echocardiography revealed a quadricuspid aortic valve. This patient underwent aortic root replacement with a valve sparing technique. Under deep hypothermic circulatory arrest with retrograde cerebral perfusion, replacement of the ascending aorta was successfully performed. The postoperative course was uneventful. This patient is doing well 6 months after surgery without recurrence of aortic regurgitation.

A 76-year-old woman with acute myocardial infarction (AMI) suddenly fell down with cardiogenic shock. Echocardiography showed free wall rupture (FWR), therefore emergency operation was performed under IABP and PCPS assistance. Seven days after initial operation, onset of ventricular septal perforation (VSP) was recognized. Eighteen days after initial operation, the infarct exclusion technique with a bovine pericardial patch was performed. She has been doing well 4 months after the operation with trivial residual shunt. Mechanical complications after AMI are classified as FWR, VSP, and papillary muscle rupture. A combination of any two types of these is called ventricular double rupture. Ventricular double rupture is a very rare condition, and its prognosis is poor. We report here a surgical case with ventricular double rupture after AMI.

A 69-year-old man with type II right-sided aortic arch (RAA) underwent an off-pump coronary artery bypass grafting (OPCAB) in December, 2017. He underwent an abdominal aortic aneurysm resection and graft replacement in April, 2018. The postoperative computed tomography (CT) that was performed in May 2018 revealed aortic dissection from the ascending aorta to the aortic arch, although he was asymptomatic. We evaluated the native coronary artery and patent bypass grafts by coronary CT. Graft replacement of the ascending aorta and partial aortic arch was carried out on an elective basis and the proximal anastomotic site of the vein grafts was attached to the prosthetic graft. Stanford type A aortic dissection (AAD) after previous coronary artery bypass grafting differs from spontaneous AAD in presentation, management and outcome. We report here a successful surgical case with RAA and AAD after OPCAB.

Cardiovascular surgeons have strong preferences regarding basic surgical skills. However, those basic skills have never been discussed great detail. The aim of this study is to survey the approach methods for axillary and subclavian artery targeting cardiovascular surgeons in Japan aged under 40, and to share the results of those basic skills.

Background/Aims:
Advanced pancreatic and biliary tract cancers can invade the duodenum and cause duodenal hemorrhagic stenosis. This study aimed to evaluate the efficacy of covered self-expandable metal stents in the treatment of cancer-related duodenal hemorrhage with stenosis.
Methods:
Between January 2014 and December 2016, metal stents were placed in 51 patients with duodenal stenosis. Among these patients, a self-expandable covered metal stent was endoscopically placed in 10 patients with hemorrhagic duodenal stenosis caused by pancreatobiliary cancer progression. We retrospectively analyzed the therapeutic efficacy of the stents by evaluating the technical and clinical success rates based on successful stent placement, degree of oral intake, hemostasis, stent patency, and overall survival.
Results:
The technical and clinical success rates were 100%. All 10 patients achieved a gastric outlet obstruction scoring system score of three within two weeks after the procedure and had no recurrence of melena. The median stent patency duration and overall survival after stent placement were 52 days (range, 20–220 days) and 66.5 days (range, 31–220 days), respectively.
Conclusions
Endoscopic placement of a covered metal stent for hemorrhagic duodenal stenosis associated with pancreatic or biliary tract cancer resulted in duodenal hemostasis, recanalization, and improved quality of life.
