Abstract Funding Acknowledgements Type of funding sources: None. Background  The autoimmune diseases (AD) have high morbidity and mortality due to their affection to the heart. Purpose Our objective was to describe the valvular heart disease (VHD) in patients with AD. Methods Patients with systemic lupus erythematous (SLE), rheumatoid arthritis (RA), and systemic sclerosis (SS) diagnosis were included, from January 1st 2008 to December 31th 2018. Prevalence rates of valve involvement were calculated. Results A total of 163 patients (57.6% with SLE, 23.3% with RA, 19.0% with SS) were included. The global prevalence of VHD was 5.4% in SLS, 23.6% en RA, and 15.9% in SS. The more affected valve in SLS was the tricuspid valve in 24% (12% with severe tricuspid regurgitation (STR), p = 0.028), in RA was the aortic valve in 26% (13% with severe aortic stenosis (SAS), p = 0.02), and with SS was the tricuspid valve in 48% (29% with moderate tricuspid regurgitation (MTR)). The calcium deposit was present in 66% in RA (37% in aortic valve, p < 0.001). The valve thickening (>5 mm) was higher in RA (50%, p < 0.001), with predominance in mitral valve (26%). Conclusions We found significant higher rates of STR in SLE, SAS in RA, and MTR in SS compared with the literature. Moreover, calcification and valve thickening were found more often in RA. Early diagnosis of subclinical VHD is mandatory to improve the long-term prognosis of these patients. Valvular heart disease.

The Impact

Abstract Background Valvular heart disease (VHD) has been caught in two important cross-currents in recent decades: aging demography and the rise of multimodality imaging and transcatheter valve therapy. In this setting, we aim to identify the distribution, characteristics, and management of Chinese VHD patients according to age. Methods China Valvular Heart Disease Cohort Study (China-VHD) was conducted from March to September 2019 in 46 centers over China. It included prospectively 12331 adults with native moderate or severe VHD, of which we described the distribution, management, and in-hospital events according to age (18–44, 45–54, 55–64, 65–74, ≥75). Multivariate Logistic regression was employed to investigate the impact of age on in-hospital events composed of in-hospital mortality, acute heart failure, and stoke. Results In Chinese VHD population, overall percentage peaked in 55–64 year olds. The frequency of multivalvular heart disease (MVHD) saw an increasing trend with age (p for trend <0.001). Of single valvular heart disease, mitral regurgitation (MR) was the most frequent left-sided VHD followed by aortic regurgitation (AR), aortic stenosis (AS), and mitral stenosis (MS). AS frequency significantly grew with age (p for trend = 0.02) while AR peaked in 18–44 year olds and fluctuated at a lower level in the older population. In contrast, mitral valve disease (MS, MR, and mixed mitral valve disease) was most frequent in 45–54 year olds and dropped with age (p for trend all <0.001). Noteworthily, all aortic valve disease was notably frequent in men whereas mitral valve disease and MVHD more common in women. Similar to developed countries, degenerative etiology rose steeply while rheumatic and congenital origin fell with age. Regarding management, surgical valve replacement rate was similar in age groups lower than 75 years old with increasing frequency of concomitant CABG. No matter aortic or mitral, the percentage of bio-prosthesis rocketed after 65 years (aortic: 74.7%, mitral: 70.6%). In multivariate logistic regression, covariables included age, sex, BMI, hypertension, diabetes, coronary heart disease, aortic disease, cardiomyopathy, COPD, NYHA class and valvular intervention. Compared to patients younger than 45, in-hospital events significantly higher in patients over 75 only (OR: 1.69 [95% CI: 1.07–2.66], p<0.02). Moreover, women showed a lower risk of in-hospital events (OR: 0.78 [95% CI: 0.63–0.96], p<0.01). Age distribution of VHD Conclusion Age plays a crucial role in valvular heart disease, best illustrated in AS. Unlike the western world, AR and MR are more frequent than AS but show a slightly decreasing trend with age. As expected, degenerative etiology is becoming more prevalent whereas rheumatism decreases. Age over 75 and male are associated with growing in-hospital events. Degenerative VHD thus present an important public-health burden. Acknowledgement/Funding Innovation project of Chinese academy of medical science

Valvular heart disease is an important cause of cardiac morbidity in developed countries despite a decline in the prevalence of rheumatic disease in those countries. This chapter discusses the many etiologies of valvular heart disease and presents methods for assessment and management. Specific valvular lesions discussed include mitral stenosis, mitral regurgitation, mitral valve prolapse, aortic stenosis, aortic regurgitation, and tricuspid and pulmonary disease. The section on tricuspid disease includes a discussion of mechanical prostheses (ball-in-cage and tilting-disk) and biologic prostheses (xenografts, allografts, and autografts) and their complications.  This review contains 5 figures, 9 tables, and 53 references.

Valve Diseases

Native mitral valve disease is the second valvular heart disease after aortic valve disease. For the last few decades, two-dimensional Doppler echocardiography was the cornerstone technique for evaluating patients with mitral valve disease. Besides aetiological information, echocardiography allows the description of valve anatomy, the assessment of disease severity, and the description of the associated lesions.This chapter will address the echocardiographic evaluation of mitral regurgitation (MR) and mitral stenosis (MS).In MR, the following findings should be assessed: 1. Aetiology. 2. Type and extent of anatomical lesions and mechanisms of regurgitation. 3. The possibility of mitral valve repair. 4. Quantification of MR severity. 5. Quantification of MR repercussions.In MS, the following findings should be assessed: 1. Aetiology. 2. Type and extent of anatomical lesions. 3. Quantification of MS severity. 4. Quantification of MS repercussions. 5. Wilkins or Cormier scores for the possibility of percutaneous mitral commissuroplasty.Management of patients with mitral valve disease is currently based on symptoms and on echocardiographic evaluation at rest. Therefore, knowing how to assess the severity of valve diseases as well as the pitfalls and the limitations of each echocardiographic method is of primary importance.

Functional capacity is the physical ability to perform a defined task. In humans it can be evaluated by using exercise testing, for instance sub-maximal exercise tests. Walking tests are widely used variations of sub-maximal exercise tests and in human medicine are considered to be realistically related to daily physical activity and prognosis in patients with heart failure. The aim of this study was to assess a sub-maximal exercise test in dogs with varying degrees of heart disease. The 6-minute walking test was used to test the functional capacity in healthy dogs and dogs with heart disease (degenerative mitral valve disease). Three groups of untrained owned dogs were compared. Two groups were dogs had mild and moderate degenerative mitral valve disease (ME-1 and ME-2, respectively) and the third group comprised healthy dogs with the same age and size conditions. Both groups of dogs with mitral valve disease walked shorter distances during 6 min (control 448.92 m; ME-1: 406.89 m; ME-2: 350.04 m). The influence of the test on the heart rate, electrocardiography and blood pressure was also evaluated. Although the 6-minute walking test has already been tested in healthy dogs, dogs with chronic pulmonary disease and dogs with artificially induced heart disease, this is the first time that this test has been validated in elderly dogs with naturally acquired heart disease. Thus, we demonstrate here that this test can be used reliably for assessing functional capacity in dogs with heart disease. &nbsp;

Ochronosis, an autosomal recessive metabolic disorder, causes an excess of homogentisic acid that results in adverse pigmentation, calcification, and inflammation of cartilaginous and other tissues. Cardiovascular abnormalities are less frequently reported than are other manifestations. In rare cases, ochronosis can cause valvular heart disease. We report the case of a 72-year-old man with aortic stenosis and mitral insufficiency who was diagnosed with ochronosis while undergoing surgical aortic and mitral valve replacement. We discuss the history and surgical management of alkaptonuric ochronosis.
