Giant aneurysm of left circumflex artery branch with fistula to the coronary sinus: a case report.

Background: Aneurysm of a coronary artery branch with a fistula is extremely rare. Here, we present a case of giant aneurysm of the left circumflex artery branch with a fistula to the coronary sinus treated successfully with aneurysmectomy.

Case Presentation: A 58-year-old woman was referred to our hospital due to an abnormal pericardial mass found by multidetector computed tomography.

The necessity of routine screening for deep vein thrombosis before surgery.

Background: Pulmonary embolism (PE) from deep venous thrombosis (DVT) can be a fatal postoperative complication. Preventive measures for venous thromboembolism (VTE) was evaluated in this hospital.

Materials And Methods: Preoperative DVT screening following surgery under general anesthesia in 2009-2016 was examined, and then, 217 patients diagnosed with DVT by preoperative leg-ultrasound (US) between 2014 and 2016 were retrospectively analyzed.

[True Ascending Aortic Aneurysm Late after Total Arch Replacement].

An aortic aneurysm was incidentally diagnosed in a 75-year-old woman during a thorough examination for other diseases. She had a history of total arch replacement( TAR) for aortic arch aneurysm 17 years previously. Contrast-enhanced computed tomography( CT) revealed a proximal aortic aneurysm with a maximum diameter of 67 mm protruding to the lateral side.

[Suspended Ventricular Septal Defect Closure Due to Heparin Resistance;Report of a Case].

We present a case of heparin resistance whereby open heart surgery was discontinued. A 53-year-old woman who was diagnosed with ventricular septal defect and atrial septal defect was scheduled for intracardiac repair. However, after intravenous heparin (400 U kg-1) supplementation, the activated clotting time (ACT) increased only to seconds.

[Midterm Outcomes of Root Replacement Using Homograft for Aortic Valve Infective Endocarditis].

From August 2003 to June 2013, 9 patients with aortic valve endocarditis underwent aortic root replacement using homografts which were harvested and preserved in our institute. The median patient age was 62 years (range 46~84) and 5 patients were men. Four cases were prosthetic valve infections.

Aortic root replacement for annuloaortic ectasia with a single coronary artery.

A single coronary artery, arising from the left sinus of Valsalva, associated with a bicuspid aortic valve and annuloaortic ectasia, is very rare. We report on a surgical case of bicuspid aortic valve regurgitation, annuloaortic ectasia, and dilation of the ascending aorta to the aortic arch in a patient with a single coronary artery. We successfully performed aortic root replacement with reimplantation of the single coronary artery and total arch replacement.

[On pump beating heart mitral and tricuspid valve annuloplasty via right mini thoracotomy approach in a patient who had undergone cardiac surgery 3 times].

The patient was an 84-year-old man. He had a history of 3-time median sternotomy with a functioning coronary bypass graft. Because of his dependence on inotropic agents caused by a progressing mitral and tricuspid valve insufficiency, we decided to perform surgery.

[Full root replacement with a Freestyle bioprosthesis for prosthetic valve endocarditis complicated by aortic-root pseudoaneurysm after subcoronary technique; report of a case].

We report a surgical case of prosthetic valve endocarditis( PVE) after aortic valve replacement with a Freestyle stentless bioprosthesis, which was successfully treated with full root replacement using a Freestyle valve. A 80-year-old man underwent aortic valve replacement with a Freestyle stentless bioprosthesis, using subcoronary technique for aortic stenosis in 2004. Three years later he had late PVE, and we found the aortic-root pseudoaneurysm.

Giant saccular aneurysm of coronary arteriovenous fistula to the main pulmonary artery: intraoperative assessment by using fluorescent imaging.

Coronary arteriovenous fistulas (CAF) and coronary artery aneurysms (CAA) are uncommon, but their detection has recently increased. In this case we succeeded in identifying the residual shunt flow by using an intraoperative fluorescence imaging technique with indocyanine green after surgical treatment. The photodynamic eye imaging system is based on fluorescence of indocyanine green.

Active infective endocarditis: management and risk analysis of hospital death from 24 years' experience.

Background: This study was performed to identify risk factors for hospital death in patients with acute and active infective endocarditis (AAIE) after surgical intervention.

Methods And Results: From 1980 to 2004, 94 patients underwent surgery for AAIE (age range, 3-77 years; 76% males). Congestive heart failure (CHF) was present in 44 patients, as well as vegetations in 64, septicemia in 16, abscesses in 17, and emboli in 22; 16 patients had prosthetic valve endocarditis.

Midterm results of Manouguian double valve replacement: comparison with standard double valve replacement.

Objective: Surgical strategies for patients who have a small aortic annulus associated with a small mitral annulus remain controversial. The objective of this study was to assess the validity of the Manouguian procedure for double valve replacement with patch enlargement of the annuli.

Methods: We reviewed 57 consecutive patients who underwent double valve replacement for combined aortic and mitral disease between September 1991 and October 2000.
