Assessment of Machine Learning Approaches to Predict in-Hospital Mortality in Patients Underwent Prosthetic Heart Valve Replacement Surgery

BACKGROUND Long-term outcome of patients treated with a St. Jude prosthetic heart valve was reported by investigators in Lausanne, Switzerland. This article quantifies the mortality and morbidity implications of single or multiple heart valve replacement. RESULTS After hospital discharge, mortality ratios were highest for duration 5-10 years, roughly comparable in patients who received a sing...

ccurate diagnosis of prosthetic heart valve infection has major implications on patient management and outcome. If the presence of prosthetic or periprosthetic valve endocarditis is misclassified, it can lead to delayed antibiotic or surgical intervention, which may adversely affect patient outcomes, and that is not inconsequential. Prosthetic valve endocarditis constitutes up to 30% of all cas...

A 55-year-old invasive/clinical cardiologist worked full time, exercised regularly, and was asymptomatic. Two weeks previously, he had new onset of angina on exertion. Echocardiography/Doppler and cardiac catheterization confirmed the clinical assessment of severe aortic stenosis with a valve area of 0.5 cm/m. The aortic valve was tricuspid; left ventricular ejection fraction was 0.60. Coronary...

giant left atria are defined as those measuring larger than 8 cm and are typically found in patients who have rheumatic mitral valve disease with severe regurgitation. enlargement of the left atrium may create compression of the surrounding structures such as the esophagus, pulmonary veins, respiratory tract, lung, inferior vena cava, recurrent laryngeal nerve, and thoracic vertebrae and lead t...

Heart valve replacement is a common cardiac surgical procedure used to treat native valvular diseases such as aortic and mitral stenosis and regurgitation. These procedures reduce the morbidity and mortality associated with diseased native valves and yet come at the expense of prosthetic valve complications. Structural valve degeneration is one such complication. We present a case of a critical...

Staphylococcus warneri, a coagulase negative staphylococcus, has been isolated in prosthetic device-related infections and has been reported as a rare cause of endocarditis. We report a case of prosthetic aortic valve S. warneri endocarditis, in which the patient lacked typical infectious signs and symptoms, instead presenting with congestive heart failure due to perforation of the valve. Provi...
