Reintervention of a mitral degenerated bioprosthesis has high surgical risk, especially in elderly patients with multiple comorbidities. We report 74 years old female two previous cardiac procedures and new structural deterioration severe regurgitation. Considering her high-surgical fully percutaneous treatment was performed balloon-expandable aortic valve position (valve-in-valve) through tran...

BACKGROUND Less invasive cardiac surgery is widely adopted nowadays. Upper or lower partial sternotomy is an approach for less invasive cardiac surgery. We report results of less invasive cardiac surgery via partial sternotomy. METHODS From August 1, 2009 to September 30, 2010, 35 patients underwent cardiac surgery via upper or lower partial sternotomy. The preoperative characteristics, opera...

BACKGROUND To retrospectively evaluate mitral valve abnormality in left atrial myxoma patients by using cardiac computed tomography (CT). MATERIAL AND METHODS Cardiac CT was performed in 56 patients with left atrial myxoma and 50 controls. Tumor and mitral valve characteristics were analyzed. The mitral valve parameters differences were compared between patients with myxoma and controls, myxo...

A 22-year-old male patient was admitted to our institution because of repeated chest pain and syncope. Physical examination was unremarkable except for a systolic murmur on cardiac auscultation. Transesophageal echocardiogram showed a large, very mobile cystic mass (21×17 mm) attaching to the bicuspid aortic valve, which caused severe left ventricular outflow tract obstruction with normal ventr...

surgery and to enhance our understanding of the pathophysiology of mitral stenosis. Although surgery produced a significant increase in calculated mitral valve area, the degree of improvement varied markedly. The younger patients had the greater increase in mitral valve area. The change in cardiac index and pulmonary vascular resistance correlated well with the change in mitral valve area. Only...

BACKGROUND Although temporary cardiac pacing is infrequently needed, temporary epicardial pacing wires are routinely inserted after valve surgery. As they are associated with infrequent, but life threatening complications, and the decreased need for postoperative pacing in a group of low risk patients; this study aims to identify the predictors of temporary cardiac pacing after valve surgery. ...

Mucopolysaccharidosis (MPS) is an inherited metabolic disease caused by deficiency of the enzymes needed for glycosaminoglycan (GAG) degradation. MPS type I is caused by the deficiency of the lysosomal enzyme alpha-l-iduronidase and is classified into Hurler syndrome, Scheie syndrome, and Hurler-Scheie syndrome based on disease severity and onset. Cardiac complications such as left ventricular ...

Congenital heart valve defects in humans occur in approximately 2% of live births and are a major source of compromised cardiac function. In this study we demonstrate that normal heart valve development and cardiac function are dependent upon Galnt1, the gene that encodes a member of the family of glycosyltransferases (GalNAc-Ts) responsible for the initiation of mucin-type O-glycosylation. In ...

The Medtronic-Hall cardiac valvular prosthesis has been available for insertion since 1977. This report reviews the English language literature concerning that valve published during the last 14 years. The review is focused on three modes of assessment. First, experience with valve implantation techniques and their results has demonstrated that with careful attention to education of the implant...

Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy. Transthoracic echocardiography revealed dilation of the left ventricle, valvular and subvalvular aortic stenosis, bicuspid aortic valve, aortic regurgitation, and mitral valve ...
