OBJECTIVE Observe the efficacy of surgical treatment in patients with severe pulmonary arterial hypertension caused by mitral valve disease. METHODS We examined the results of surgical treatment in 32 patients with mitral valve disease and severe pulmonary arterial hypertension (pulmonary arterial systolic pressure ≥ 80 mmHg) retrospectively. Operative and postoperative data collection includ...
To minimize the weight of the prosthesis various techniques that create a hollow prosthesis have been known. There are a lot of drawbacks of these techniques as they are complex, time consuming, and of high cost. Here is a technique that utilizes putty material for fabricating hollow denture prosthesis.

BACKGROUND The impact of aortic prosthesis-patient mismatch (P-PtM) on long-term survival is unclear. METHODS AND RESULTS Between 1985 and 2000, 388 patients at Mayo Clinic in Rochester, Minn, underwent aortic valve replacement (AVR) with 19- or 21-mm St Jude Medical prostheses and had transthoracic echocardiography within 1 year after AVR. Mean age of patients was 62+/-13 years; 69% were fem...
OBJECTIVES The purpose of this analysis was to assess 5-year outcomes of transcatheter aortic valve implantation (TAVI) using the current technology of the self-expanding CoreValve prosthesis (Medtronic Inc., Minneapolis, Minnesota). BACKGROUND There is a paucity of evidence on long-term durability of currently available transcatheter heart valves. METHODS Starting in June 2007, all consecu...
INTRODUCTION Percutaneous transcatheter aortic valve implantation (TAVI) has become an established therapy for inoperable and high-surgical-risk patients with severe aortic stenosis. Although TAVI in patients with degenerated surgical aortic bioprostheses (i.e. valve-in-valve TAVI) is increasingly reported in Western studies, such data is lacking in Asian patients. We describe the initial exper...
Sound spectroanalysis was carried out for diagnosis of malfunctioning prosthetic heart valves in 50 cases, which consisted of 31 mitral, 14 aortic, 4 mitral+aortic and 1 tricuspid valve replacements with the age ranging from 17 to 57 years. Types of prosthetic valves used in this series were Starr-Edwards silicon ball valves, metal ball valves, disc valves, Kay-Shiley valves, Smeloff-Cutter val...
conclusions preservation of mitral annulus and papillary muscle continuity may enhance post- mvr cardiac performance with low mortality and morbidity rates. the risk of pvd was not significantly higher than conventional mvr in our series. results the improvement of functional status was seen in almost all survivors but was more obvious in the group i. in early follow-up, 56.4% of group i cases ...
a 45- year old man with a history of aortic valve replacement presented with acute chest pain which was diagnosed to be anterior wall myocardial infarction. he received thrombolytic therapy with streptokinase. echocardiography and fluoroscopy showed normally functioning ball and cage aortic prosthesis. coronary arteriography showed globular filling defect in midportion of left anterior descendi...
