[Early Structural Valve Deterioration of Bioprosthetic Mitral Valve in a Dialysis Patient].

Choice of prosthetic valve during valve replacement in dialysis patients is still controversial. There is a known risk of early structural valve deterioration of bioprosthesis in dialysis patients, whereas mechanical prosthesis is associated with a higher risk of bleeding and thrombotic events. A 68-year-old dialysis-dependent woman, who had undergone bioprosthetic mitral valve replacement at the age of 66, was admitted to our hospital because of general malaise and hypotension during dialysis.

[Mitral Valve Replacement and Cardiac Resynchronization Therapy for Mitral Regurgitation with Left Ventricular Noncompaction:Report of a Case].

Left ventricular noncompaction (LVNC) is a rare congenital abnormality resulting from an arrest of the normal process of myocardial compaction. LVNC has been known as a disease of infants, however, some surgical cases of LVNC in adult have been reported. A 61-year-old man who was diagnosed as dilated cardiomyopathy due to LVNC was admitted to our hospital because of dyspnea.

[Angina Pectoris due to Anomalous Aortic Origin of the Right Coronary Artery;Report of a Case].

A 45-year-old woman was admitted to our hospital because of chest pain on exertion. She was diagnosed to have an anomalous aortic origin of the right coronary artery(RCA) arising from the left sinus of Valsalva, passing between the aorta and the main pulmonary artery. Exercise treadmill test demonstrated significant depression of ST segments in leads II, III and aVF.

[Beating Mitral Valve Replacement for Functional Mitral Regurgitation after Cardiac Resynchronization Therapy;Report of a Case].

A 72-year-old man was admitted to our hospital because of dyspnea. He had a history of cardiac resynchronization therapy for congestive heart failure due to dilated cardiomyopathy 6 months previously. Echocardiography revealed severe functional mitral regurgitation which had been mild 6 months before.

[Double Valve Replacement and Tricuspid Annuloplasty in a Patient with Situs Inversus Totalis and Mirror-image Dextrocardia;Report of a Case].

Situs inversus totalis and mirror-image dextrocardia is a rare congenital anomaly. A 79-year-old man with a history of atrial fibrillation presented to our hospital with chest oppression. Chest X-ray and computed tomography showed mirror-image dextrocardia and situs inversus totalis.

[Early outcomes of isolated aortic valve replacement in octogenarians].

We retrospectively studied early outcomes of isolated aortic valve replacement (AVR)in octogenarians. From November 2006 to October 2012, 70 patients underwent AVR and we divided them into 2 groups:group O (24 patients aged 80 years or older, 80~91 years;mean age, 85.0 years);and group Y(46 patients aged younger than 80, 39~79 years;mean age, 69.

Left ventricular restoration for ischemic cardiomyopathy--comparison of presence and absence of mitral valve procedure.

Objective: Association of mitral regurgitation (MR) with ischemic cardiomyopathy (ICM) increases the degree of heart failure and its surgical management remains controversial. The aim of this study was to report the surgical results in patients with or without MR in association with ICM.

Patients And Methods: Ninety-two patients with ischemic cardiomyopathy (left ventricular [LV] ejection fraction less than 30% with global akinesis) underwent LV restoration.
