Abstract Background and Aims Valvular heart disease (VHD) is highly prevalent in maintenance haemodialysis patients. This high prevalence is associated with poor outcomes and higher mortality [Samad et al., Journal of the American Heart Association, 6 (10), (2017)]. Previous large studies found VHD prevalence between 14% and 16% among prevalent haemodialysis patients [2018 USRDS Annual Data Report | Vol 2] [Hickson et al., Journal of the American College of Cardiology, 67(10), (2016)]. KDIGO consensus group identified several evidence gaps where research is necessary in order to improve our understanding of diagnosis and management of VHD in this population [Marwick et al., Kidney international, 96 (4), (2019)]. The aim of our study is to assess the burden of VHD in a large cohort of haemodialysis recipients in one center in the United Kingdom (UK). Method This is a retrospective cross-sectional evaluation of valvular heart disease in prevalent haemodialysis patients. Prevalent haemodialysis recipients were defined as patients established on haemodialysis for ≥ 3 months. Echocardiographic data was collected for all patients. Patients were considered to have VHD if they had significant aortic (AVD) or mitral valve disease (MVD) based on standard echocardiographic criteria. These valvular diseases are classified as mild, moderate or severe. Here, we report some descriptive statistics from our data. Results The study group includes 544 prevalent haemodialysis patients. Mean age was 62 years (SD 15.28), 40% females and 60% were males. Median dialysis vintage was 1.9 years (IQR 1, 3.2) [Range: 0.2, 10.2]. 14 % of patients received home-based hemodialysis and 86% received in-center dialysis. 30% of patients were actively awaiting a transplant. A total of 1155 echocardiography studies were reviewed. Of the 425 patients who had an echocardiogram; 34% (n=143) had evidence of VHD as defined above. Significant AVD was identified in 18% of patients (n=78). The dominant lesion was aortic regurgitation in 11%, and aortic stenosis in 7% of patients. 20% of patients (n=85) had significant MVD with mitral valve stenosis in 0.7% of patients (n=3) and mitral regurgitation in 18% of patients. 5% of patients had cardiothoracic intervention (n=21) for valvular heart disease, which included aortic valve replacement (n=9), transcatheter aortic valve implantation (TAVI) (n=9), and mitral valve replacement (n=3). Conclusion We found that at least one third (34%) of patients in this cohort had significant VHD- higher than the previously published figures. The numbers are likely to be higher, if echocardiogram information was available for all patients in the study. Timely echocardiographic studies and follow-up imaging for those with established disease are essential to identify patients with significant VHD, in order to establish impact of disease on both dialysis delivery and patient symptoms.

Abstract Background Granulomatosis with polyangiitis (GPA), formerly known as Wegener’s granulomatosis, is a systemic inflammatory process predominantly affecting upper and lower respiratory tract and kidneys. Valvular heart disease is a rare manifestation of GPA. Case summary We report two cases of acute valvular heart disease mimicking acute endocarditis caused by GPA. Both patients were middle-aged females with acute aortic valve regurgitation suggestive of possible infective endocarditis. In their recent medical history, atypical otitis and sinusitis were noted. The first patient was admitted with heart failure and the second patient because of persisting fever. Echocardiogram revealed severe aortic regurgitation with an additional structure on two cusps, suggestive of infective endocarditis in both patients. Urgent surgical replacement was performed; however, intraoperative findings did not show infective endocarditis, but severe inflammatory changes of the valve and surrounding tissue. In both patients, the valve was replaced by a prosthetic valve. Microscopic examination of the valve/myocardial biopsy showed diffuse acute and chronic inflammation with necrosis and necrotizing granulomas, compatible with GPA after infectious causes were excluded. Disease remission was obtained in both patients, in one patient with Rituximab and in the other with Glucocorticoids and Cyclophosphamide. Both had an uneventful follow-up. Discussion Granulomatosis with polyangiitis can be a rare cause of acute aortic valve regurgitation mimicking infective endocarditis with the need for surgical valve replacement. Atypical ear, nose, and throat symptoms can be a first sign of GPA. Symptom recognition is important for early diagnosis and appropriate treatment to prevent further progression of the disease.

Abstract Background Transcatheter aortic valve replacement (TAVR) in combination with a valve-in-valve (V-i-V) transcatheter mitral valve replacement (TMVR) is a rare procedure in comparison to surgical therapy especially in young patients. We report on a young patient at high surgical risk, receiving a double valve implantation with two S3 transcatheter heart valves. Case summary A 59-year-old female patient with two previous mitral valve replacements due to endocarditis and re-endocarditis experienced a new onset of severe mitral valve stenosis in combination with progredient aortic stenosis. She was admitted to the hospital with severe dyspnoea and intermittent non-invasive ventilation [New York Heart Association (NYHA) III–IV]. An interventional transapical transcatheter double valve implantation was planned and carried out due to cardiac decompensation and high comorbidity preoperatively (STS score of 6.92). At 6-month follow-up, the patient presented herself in an improved condition with reduced symptoms (NYHA I–II), a good functional status of both valves and an advanced right and left ventricular function in the echocardiogram. Discussion Even in younger patients at high risk, a combined native TAVR and V-i-V TMVR procedure can be performed. In this case, a transcatheter SAPIEN 3 valve was transapically implanted with good clinical mid-term outcome at 6 months.

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.

Introduction: Multiple valvular heart disease (mVHD) caused by mixed stenotic and regurgitant lesions involving at least two valves is a common condition which is poorly understood and challenging to manage. Herein, we simulate the hemodynamics of a patient with mVHD before and after transcatheter aortic valve replacement (TAVR) to better understand the physiology of this complex disease. Case: A 67-year-old man with celiac enteropathy presented to a local hospital with dyspnea, hypotension, and oliguria. Echocardiography revealed a dilated left ventricle (end-diastolic diameter [LVEDD] 6.7 cm) with an ejection fraction (EF) of 20% and multiple severe valvulopathies, including aortic stenosis (AS), aortic regurgitation (AR), and mitral regurgitation (MR). Right heart catheterization revealed a low cardiac index (1.76 L/min/m 2 ) and a high wedge pressure (36 mmHg) with V-waves exceeding 50 mmHg. The patient’s severe AR precluded mechanical circulatory support, so TAVR was emergently performed in the setting of worsening cardiogenic shock (CS) with a 29 mm self-expanding bioprosthesis via transfemoral access. Valve deployment was successfully guided by fluoroscopy and transthoracic echocardiography alone. CS resolved in the subsequent 48 hours, and at 3-month follow-up, his LV EF returned to 55% and LVEDD decreased to 4.4 cm. LV pressure-volume loops pre- and post-TAVR were generated using a cardiovascular physiology simulator (Fig. 1). TAVR’s correction of the patient’s severe AS and AR produced immediate energetic benefits, with pressure-volume area declining 13% and cardiac power output increasing 2.24-fold. Conclusions: This challenging case and the accompanying pressure-volume analysis affirms the feasibility of emergent TAVR in highly selected patients, the procedure’s ability to immediately improve ventricular performance, and the LV’s capacity to remodel when operating under more physiologic loading conditions.
