BACKGROUND
Dyspnea is a common symptom in a patient with valvular heart disease. The mechanism underlying this disease is still uncertain. Respiratory muscle weakness has been proposed to be one of the mechanisms underlying dyspnea in heart failure, but this has not been adequately studied in
Surgical treatment of mitral stenosis (MS) usually consists of open mitral commissurotomy (MC) or percutaneous balloon MC, which require a cardiopulmonary bypass or transseptal approach, respectively. We describe here the first surgical management of congenital MS in a dog using a less invasive
Mixed-typed cryoproteins, consisting of IgG and IgM, were demonstrated in the sera of four sisters. While the IgG component was polyclonal in every instance, in two of them the IgM component was found to be monoclonal with type chi light chains. Clinical diagnoses included the
Myasthenia gravis is an autoimmune disease characterised by weakness of the skeletal muscles, with remissions and exacerbations due to antibodies acting on the acetylcholine receptors. This leads to the characteristic defect transmission in the neuromuscular junction. Treatment includes

BACKGROUND
Weakness and fatigue are accepted as normal accompaniments of aging. Usually, older individuals are not investigated with much enthusiasm but a treatable cause is discernible on several occasions.
METHODS
We had a 67 year old hypertensive lady with a mitral stenosis, presenting in
BACKGROUND
Intracardiac myxomas are frequent benign tumors of the heart and typically localize in the left atri- um and interatrial septum. When myxomas generate at other sites, they are designated as atypical. Mutations in the PRKAR1A gene (a tumor suppressor gene that encodes a protein kinase A
Traumatic intravascular hemolysis after heart valve replacement can be a serious problem. It is commonly associated with either structural deterioration or paravalvular leaks. A 63-year-old woman with a six-year history of surgery for mitral stenosis presented with complaints of weakness and
A 58-year-old woman was hospitalized because of shortness of breath, cough, weakness, and physical signs suggestive of mitral stenosis. Echo-Doppler examination revealed a left atrial mass. This was removed and turned out to be a fibrosarcoma. Recurrence of the tumor with metastases into the
A 42-year-old woman with chronic mitral stenosis was admitted for progressive dyspnea, palpitation, and weakness of lower extremities. Echocardiography revealed rheumatic, thickened, and stenotic mitral and aortic valves, and two free-floating ball thrombi were detected in the left atrium and
