[Valve Re-replacement Combined with Patch Enlargement of the Aortic Annulus for Bioprosthetic Valve Deterioration;Report of a Case].

A 42-year-old woman had undergone aortic valve replacement with a 19 mm bioprosthetic valve for aortic stenosis due to a bicuspid valve 8 years before. She was admitted to our hospital for valve re-replacement owing to the prosthetic valve dysfunction. As the patient's valve annulus was markedly thickened owing to pannus formation, we were unable to pass a 19 mm valve sizer through the annulus even after removal of the prosthetic valve and the tissue surrounding the annulus.

Exacerbation of severe constrictive pericarditis after prior inadequate pericardiectomy.

Pericardiectomy is commonly used to treat constrictive pericarditis (CP); however, persistent calcification can complicate recovery. An 82-year-old man presented with CP following an inadequate pericardiectomy at another hospital two years earlier. He was referred to our hospital with a diagnosis of recurrent CP.

[Patch Closure of Posterior Type Ventricular Septal Perforation with Posterior Left Ventricular Aneurysm through Right Ventricular Incision].

We report a case of patch closure of posterior type ventricular septal perforation (VSP) with posterior left ventricular aneurysm (PLVAN) through right ventricular incision. A 70-year-old man was transferred to our hospital because of persistent epigastric pain. He was diagnosed with inferior acute myocardial infarction, and percutaneous coronary intervention was performed to the right coronary artery[ atrio-ventricular(AV)].

Surgical treatment for saphenous vein graft aneurysm without redo sternotomy.

Background: Saphenous vein graft aneurysm (SVGA) is a rare complication after coronary artery bypass grafting; however, it may lead to fatal conditions. A redo sternotomy poses a high risk of injury to the patent graft.

Case Report: A 59-year-old man with chest pain was diagnosed with a giant SVGA (67 mm) anastomosed to the right coronary artery (RCA) and compressing the right atrium.

Surgery for Acute Type A Aortic Dissection in A Pregnant Woman At 28 Weeks' Gestation.

A 27-year-old woman with sudden back pain was transported to our hospital. Abdominal ultrasonography revealed pregnancy of 28 weeks' gestation. Computed tomography demonstrated a type A aortic dissection.

[Acute Pancreatitis after Thoracoabdominal Aortic Aneurysm Repair in Patient Having a History of Pancreaticoduodenectomy;Report of a Case].

A 76-year-old man who have a history of pancreaticoduodenectomy was admitted to our hospital for surgical treatment of pararenal abdominal aortic aneurysm. He underwent thoracoabdominal aortic aneurysm repair through the Stoney's thoracoabdominal incision under partial cardiopulmonary bypass. Postoperatively, laboratory examination showed elevated pancreatic amylase and computed tomography revealed acute pancreatitis.

[Surgical Experience of Mitral Valve Plasty in Patient with Persistent Left Superior Vena Cava;Report of a Case].

A 45-year-old man diagnosed with severe mitral regurgitation was admitted to our hospital for surgical treatment. Preoperative computed tomographic imaging revealed a persistent left superior vena cava. At operation, cardiopulmonary bypass was established with ascending aortic and bicaval cannulation.

Cardiac tamponade caused by acute coxsackievirus infection related pericarditis complicated by aortic stenosis in a hemodialysis patient: a case report.

Background: Pericardial effusion is observed in the majority of viral pericarditis cases; however, viral pericarditis accompanied by a large effusion resulting in cardiac tamponade is rare.

Case Presentation: Here, we report the case of a 75-year-old hemodialysis patient with acute viral pericarditis complicated by aortic stenosis. The patient was referred with a diagnosis of aortic stenosis and pericardial effusion.

[Clinical Experience of Aortic Valve Replacement Using the New Stentless Bioprosthesis].

Background: The SOLO SMART valve is a bovine pericardial stentless bioprosthesis which shows superior hemodynamic performance compared to the stented valves. It is designed for supraannular and subcoronary implantation. We report our surgical experience and results in patients undergoing aortic valve replacement(AVR) with this new bioprosthesis.

Proximal first: a beneficial strategy for no-touch saphenous vein graft.

In the mid-1990s, a novel saphenous vein harvesting technique, in which the vein is harvested with its surrounding tissue without manual distention, was introduced. This no-touch technique provides an excellent long-term patency; however, graft twisting and kinking should be given attention. To fully bring out the benefit of the no-touch method while reducing the risk of twisting and kinking, we have modified the anastomosis strategy.
