[Mycotic Aneurysm of Distal Aortic Arch, after Total Arch Replacement with Open-stent Graft;Report of a Case].

The patient was a 72-year-old man, who had undergone total arch replacement with an open-stent graft due to saccular aneurysm of distal arch, 2 years before. He was admitted to a local hospital with the complaint of high fever, and was diagnosed as having pyothorax, after computed tomography (CT) scanning. After transferred to our hospital, he was treated by drainage, and antibiotic therapy.

[Successful management of aorto-esophageal fistula, using staged 3 times operation].

A 66-year-old man, presented with hematemesis and hemorrhagic shock, was transported to our institution. Computed tomographic examination suggested a pseudo-aneurysm formed by bleeding from aorto-esophageal fistula( AEF). We planned staged operations.

[Discrete type subaortic stenosis disclosed by hemolytic anemia after aortic and mitral valve replacement].

We report a case of discrete type subaortic stenosis disclosed by hemolytic anemia 7 years after aortic and mitral prosthetic valve replacement. A 53-year-old female complained of general fatigue, dyspnea, macrohematuria and hemolysis. She had undergone aortic valve replacement for non-coronary cusp perforation 15 years before, and mitral valve replacement and tricuspid annuloplasty 7 years before.

[Y-graft replacement with left renal artery reconstruction for acute aortic dissection type B].

A 56-year-old male was admitted to our hospital for acute type B aortic dissection. He received conservative therapy but follow-up computed tomography (CT) revealed a low-enhanced left kidney and severe stenosis of the left common iliac artery due to the expansion of the false lumen. Serum blood urea nitrogen (BUN) and creatinine increased and renovascular hypertension worsened with severe intermittent claudication of the left leg.

[Successful postoperative percutaneous cardiopulmonary support( PCPS) for the right-heart failure in a patient with recurrent mitral valve stenosis and a calcified left atrium; report of a case].

A 79-year-old female underwent open mitral commissurotomy and thrombectomy for mitral valve stenosis and thrombus in the left atrium 21 years ago. She was admitted for congestive heart failure because of recurrent mitral valve stenosis. Cardiac echocardiography showed severe mitral valve stenosis and the calcification of the left atrium wall.

[Giant pseudoaneurysm of the ascending aorta following the aortic valve replacement;report of a case].

56-year-old male, who had undergone re-aortic valve replacement (AVR) 33 years ago, received preoperative study for pancreatic surgery. Computed tomography (CT) revealed a giant pseudoaneurysm (7 cm diameter) of the ascending aorta. The ascending aorta was not dilated.

[Ventricular septal rupture and right ventricular free wall rupture after acute myocardial infarction].

Cardiac rupture is a catastrophic complication of acute myocardial infarction with highly mortality rate. Three types of rupture are ventricular free wall rupture( VFR), ventricular septal rupture( VSR), and papillary muscle rupture( PMR). A combination of any 2 types of rupture is called ventricular double rupture (VDR), and very rare.

Congenital unicuspid aortic valve stenosis in siblings.

We reported the case of unicuspid aortic valve in sibling, suggesting the familial incidence and genetic relation. A 41-year-old man (elder brother) with 79 mmHg of aortic valvular peak pressure gradient (peak PG) underwent aortic valve replacement with mechanical prosthetic valve (ATS 21 mm). The intraoperative finding showed the unicuspid aortic valve with one rudimentary commissure.

[New technique of concomitant replacement of the aortic valve and the ascending aorta with enlargement of the aortic annulus for congenital bicuspid aortic valve].

Congenital bicuspid aortic valve (BAV) is one of the most common congenital heart diseases, with a high incidence of associated valvular lesions and aortic abnormalities including aortic stenosis( AS), aortic regurgitation, aortic dilatation, and aortic dissection. Patients with BAV and AS often have a small aortic annulus. We encountered a case of BAV in which a 51-year-old woman with severe AS having a small aortic annulus and a dilated ascending aorta required surgical intervention.

Adventitial cystic disease of the popliteal artery.

We describe a patient with adventitial cystic disease of the popliteal artery with intermittent claudication involving the right calf during exercise. Magnetic resonance imaging (MRI) and computed tomography (CT) revealed a cystic lesion that encircled and compressed the popliteal artery. Resection of the cyst involving a segment of the affected popliteal artery and interposing an autologous vein graft resolved the symptoms, and the postoperative course was uneventful.

[Management of a lung tumor accompanied by aortic dissection; report of a case].

During an annual health check-up, a 75-year-old man was admitted to our hospital due to an abnormal shadow in the left upper lung field. A computed tomography (CT) scan taken at his 1st hospital visit showed a calcified nodule in the left upper lobe and Stanford type A aortic dissection. We could not perform bronchofiberscopy due to the risk associated with the aortic dissection and could not make a diagnosis prior to surgery.
