This case report was an attempt to present the importance of diagnostic echocardiography and closure of a patent foramen ovale in carcinoid heart disease. Herein, we present a case of a 48-year-old woman with a carcinoid metastasis presenting with tricuspid regurgitation, pulmonic stenosis, patent foramen ovale, and borderline left ventricular ejection fraction on an echocardiogram. Surgical in...
Mitral valve disease is quite variable and can occur as an isolated defect or in association with other complex left sided lesions. These lesions are often best described with detailed pre-operative imaging studies to define the valve anatomy and to access associated left heart disease. Depending on the type of mitral valve disease, various surgical repair techniques have led to improved surviv...
Rheumatic disease is an important cause of inflammatory native heart valve disease. However, with increased understanding of the pathoetiology of valve disease and valve injury, it is evident that inflammation may play a role in many valve disorders. We are only beginning to understand these complex processes. With increasing knowledge that many of these processes are active, there may be oppor...
BACKGROUND The interest in beating heart surgery is growing since better results can be obtained with this procedure compared to conventional myocardial protection techniques using cardioplegic solutions. This led us to consider mitral valve replacement with beating heart. OBJECTIVES This study aimed to determine the safety and efficacy of beating heart mitral valve replacement without cross ...
Theoretical models of the human heart valves are useful tools for understanding and characterizing the dynamics of healthy and diseased valves. Enabled by advances in numerical modeling and in a range of disciplines within experimental biomechanics, recent models of the heart valves have become increasingly comprehensive and accurate. In this paper, we first review the fundamentals of native he...
proper education and notification of patients undergoing heart valve replacement is of paramount importance. the past decade has witnessed a growing interest in the use of modern, advanced technologies in medicine and patient education. this study aimed to introduce an education-notification application for patients undergoing heart valve replacement. research was carried out in two phases of s...
Infective endocarditis (IE) is the infection of endocardial surface heart. IE rare disease with significant complications which require early diagnosis and proper treatment for reducing morbidity mortality.IE vegetation on pulmonary valve, leaflets are uncommon. However, we have diagnosed one case infective associated Multisystem Inflammatory Syndrome in Children (MIS-C) related COVID-19. MIS-C...
Infective endocarditis involving an apparently structurally normal valve: new epidemiological trend?
Infective endocarditis (IE) has been increasingly diagnosed in patients without previously detected predisposing heart disease, but its clinical features have yet to be fully determined. A recent single-center study including echocardiographic images and surgical findings investigated the incidence of undiagnosed, clinically silent valvular or congenital heart diseases and healthcare-associated...
A 66-year-old woman was diagnosed with hepatic metastasized carcinoid tumor of the ileocecal junction resulting in elevated plasma chromogranin A levels and urinary 5-hydroxyindoleacetic acid (5-HIAA) levels. Further examination showed right-sided heart failure with severe tricuspid valve regurgitation. Carcinoid tumors produce serotonin which leads to flushing, secretory diarrhea, bronchospasm...
The burden of heart valve disease is rising in line with increasing life expectancy and the prevalence of moderate or severe disease is 13% in people aged ≥75 years old.1 The most common lesions are aortic stenosis (Figure 1) due to calcific disease and mitral regurgitation (Figure 2) as a result of mitral prolapse or secondary to left ventricular dysfunction. Untreated valve disease leads to p...
