Cardiac Valve Involvement in Takayasu Arteritis Is Common: A Retrospective Study of 1,069 Patients Over 25 Years

Novel Imaging Approaches to Cardiac Manifestations of Systemic Inflammatory Diseases: JACC Scientific Statement

Derangements in the innate and adaptive immune responses observed in systemic inflammatory syndromes contributes to unique elevated atherosclerotic risk and incident cardiovascular disease. Novel multimodality imaging techniques may improve diagnostic precision for the screening and monitoring of disease activity. The integrated application of these technologies lead to earlier diagnosis and noninvasive monitoring of cardiac involvement in systemic inflammatory diseases that will aid in preclinical studies, enhance patient selection, and provide surrogate endpoints in clinical trials, thereby improving clinical outcomes. We review the common cardiovascular manifestations of immune-mediated systemic inflammatory diseases and address the clinical and investigational role of advanced multimodality cardiac imaging.

Exploring Cardiovascular Manifestations in Vasculitides: An In-Depth Review

Systemic vasculitides encompass a cluster of autoimmune diseases that affect blood vessels, and are characterized by immune-mediated injury to either small- or large-sized blood vessels. Individuals afflicted with systemic vasculitides experience notable morbidity and mortality attributable to cardiovascular manifestations. Noteworthy among these are ischemic heart disease, venous thromboembolism, aortic involvement, valvular irregularities, myocarditis, and pericarditis. This narrative review investigated and evaluated the prevalent cardiovascular disturbances commonly associated with different types of vasculitides. This review also discusses the mechanisms that underlie these manifestations. It also provides a thorough explanation of the many diagnostic techniques essential for detecting the disease at its occult stage. It is essential for healthcare professionals to have knowledge of the cardiovascular complications caused by vasculitides, as this enables them to promptly recognize these symptoms and employ suitable diagnostic techniques early on. By doing so, timely detection can be ensured, which will subsequently aid in initiating appropriate treatment strategies that are vital for decreasing morbidity and mortality in patients with systemic vasculitides.

Cardiac involvement and cardiovascular risk factors in pediatric primary systemic vasculitides

Pediatric primary systemic vasculitides are a complex group of diseases. Vasculitis subgroups are mainly determined according to the size of the predominantly affected vessels. In patients with primary systemic vasculitis, the location of vascular involvement, the size of the vessels, the extent of vascular damage, and the underlying pathology determine the disease phenotype and severity. Cardiac involvement is rare in some pediatric vasculitis, such as IgA vasculitis and polyarteritis nodosa, while it is more common in some others like Kawasaki disease and Takayasu arteritis. On the other hand, chronic inflammation in the setting of systemic vasculitis forms a major cardiovascular risk factor. Accelerated atherosclerosis and the tendency to thrombosis are the main issues determining the cardiovascular risks in pediatric systemic vasculitis. Early diagnosis and treatment are essential in these patients to minimize morbidity and mortality. In this review, we aimed to raise physicians' awareness of cardiac involvement and cardiovascular risks in pediatric patients with primary systemic vasculitis.

A Case Report of Differential Diagnosis of Causes of Severe Valvular Heart Disease (Takayasu's Arteritis, Infective Endocarditis and Myxomatous Degeneration) with the Key Role of Histological and PCR Examination

Aortic valve lesion is a common and may have diverse causes, from degenerative, congenital and infectious diseases to autoimmune conditions. We present a rare case of Takayasu arteritis and severe heart lesion due to the myxomatous degeneration of the aortic and mitral valves associated with development of infective endocarditis (IE) complicated by abscess, fistula, valve perforation and recurrent acute decompensated heart failure in a young female patient. A combined use of histopathological and PCR analyses of valve tissues was critically important for differential diagnosis of the valve lesions, as it made it possible to identify the true cause of the disease. The presence of Takayasu arteritis has played an indirect role by creating conditions for the development of immunosuppression and determining the disease severity and its progression.

Risk factors of aortic regurgitation progression in Chinese patients with Takayasu's arteritis: a prospective cohort study

OBJECTIVE

To elucidate the 3-year follow-up outcomes and risk factors associated with aortic regurgitation progression in Takayasu's arteritis (TAK).

METHODS

This study was a prospective cohort study conducted among 77 patients with TAK at Zhongshan Hospital, Fudan University, China. All the participants were followed up and assessed with echocardiography for 3 years, and the baseline characteristics and dynamic changes in the aortic valve were recorded and investigated. A multivariable Cox model was used to explore the risk factors for aortic regurgitation progression.

RESULTS

The median onset age was 36.9 (26.0-44.4) years, and 57 patients (74.0%) were females. Fifty patients (64.9%) complained of aortic regurgitation, which was the most common valvular lesion at baseline. During the 3-year follow-up period, the progression of aortic regurgitation was observed in 29 (37.7%) patients with TAK. The progression group had higher baseline erythrocyte sedimentation rate (ESR; p = 0.013) and interleukin (IL)-6 (p = 0.029) levels and lower early treatment remission rates (p = 0.024). According to the Cox model, the elevated baseline IL-6 level [>13 pg/ml, hazard ratio (HR) = 2.4, 95% confidence interval (CI) = 1.0-5.8, p = 0.042] and absence of early treatment remission (HR = 3.3, 95% CI = 1.3-8.2, p = 0.010) were the independent risk factors for aortic regurgitation deterioration.

CONCLUSION

About one-third of patients with TAK experienced aortic regurgitation progression within 3 years from first admission. Elevated IL-6 levels at baseline and absence of early treatment remission were the two important risk factors for subsequent aortic regurgitation progression.

Clinical characteristics and outcomes in patients with Takayasu arteritis coexisting with myocardial ischemia and neurological symptoms: A multicenter, long-term, follow-up study

Background

The incidence of coexisting myocardial ischemia and neurological symptoms in Takayasu arteritis (TA) is currently unknown. There is no standardized treatment algorithm in complex cases involving the coronary and intracranial arteries.

Objective

This study aimed to describe the clinical characteristics and outcomes in patients with TA coexisting with myocardial ischemia and neurological symptoms.

Methods

We retrospectively collected and assessed 1,580 patients with TA, and enrolled patients with myocardial ischemia and neurological symptoms from January 2002 to December 2021 in several hospitals. The incidence, clinical features, management strategy, and prognosis of these patients were evaluated.

Results

Ninety-four (5.9%, 94/1,580) patients with TA coexisting with myocardial ischemia and neurological symptoms were included in the present study. Imaging results showed that the subclavian arteries were the most frequently affected arteries and 37 patients had intracranial vascular abnormalities, comprising the basilar artery (6.1%, 17/279), middle cerebral artery (2.5%, 7/279), anterior cerebral artery (2.9%, 8/279), and posterior cerebral artery (1.9%, 5/279). Among patients with neurological symptoms, 25 patients underwent percutaneous transluminal angioplasty and 20 patients underwent stent implantation. The most common site of stenosis was the ostial and proximal segments of the coronary artery, with 142 lesions among 188 (75.5%) lesions. Thirty-eight patients adopted interventional therapy, 21 patients underwent surgical treatment, and the remaining 35 patients received conservative treatment. There were 20 (21.27%, 20/94) late deaths during a mean follow-up of 57.79 months. The mortality rate in the conservative treatment group was significantly higher than that in the interventional therapy and surgical treatment groups.

Conclusion

Patients with TA involving both the coronary and intracranial vessels are not rare. Stenosis and occlusion lesions most frequently involve the ostia and proximal segment of the arteries. Severe vascular lesions should be revascularized as soon as possible. These patients should be supplemented with glucocorticoids, antiplatelet, nitrates, and statins.

Cardiothoracic surgery and peripheral endovascular intervention in cardiovascular damage from a cohort of orphan rheumatological diseases-epidemiological and survival analysis

Background

Aortic diseases in some orphan rheumatological diseases require medical, surgical or peripheral endovascular intervention because they can be catastrophic. Objectives: to analyze the main clinical and epidemiological characteristics of patients with Takayasu arteritis (TA), Marfan syndrome (MS) and similar conditions that were treated with cardiothoracic surgery and peripheral endovascular intervention.

Methods

Retrospective and descriptive cohort study that included patients of any age and gender with TA (as per the criteria of the American College of Rheumatology and EULAR/PRINTO), MS (according to Ghent criteria), and similar conditions who underwent cardiothoracic surgery or peripheral endovascular intervention. Data were collected from electronic charts.

Results

A total of 77 patients with TA and 135 patients with MS and similar conditions were included. The frequency of surgical or interventional requirements in patients with TA and MS/similar conditions was 77/364 (21.2%) and 135/300 (45%), respectively; such patients were followed for a median of 6 [2–12] and 3.29 (0.42–6.62) years, with (maximum follow-up range of 47 and 21.37 years, respectively). Aneurysms were present in 11 (14.3%) and 66 (48.9%) in patients with TA and MS/similar conditions, respectively. Aortic, mitral and tricuspid valve damage occurred in 8 (10.4%) patients, 4 (5.2%) patients and 1 (1.3%) patient with TA, respectively; corresponding frequencies in patients with MS/similar conditions were 98 (72.6%), 50 (37.0%) and 20 (14.8%). We identified that 20% of patients with TA died after 5.08 years (95% CI: 0.23–25.42 years) and 20 % of the patients with MS and other similar conditions died after 7.52 years (95% CI: 1.10–9.02 years).

Conclusions

The frequency of surgical intervention was low in this study. Long-term prognosis is good if surgery is performed in a timely manner. Epidemiological studies provide relevant information for public health decisions related to the management of orphan rheumatological diseases.

Risk factors and surgical prognosis in patients with aortic valve involvement caused by Takayasu arteritis

Objective

Aortic valve involvement is not uncommon in patients with Takayasu arteritis (TAK) and leading to poor prognosis. The aim of our study was to explore the risk factors of aortic valve involvement and to evaluate the prognosis in TAK patients with aortic valve involvement.

Method

In this retrospective study, 172 TAK patients were divided into groups with or without aortic valve involvement to identify the risk factors. Patients who underwent aortic valve surgical treatment were followed up to assess cumulative incidence of postoperative adverse events.

Results

A total of 92 TAK patients (53.49%) had aortic valvular lesion. The infiltration of inflammatory cells was found in surgical specimens of aortic valve. Numano type IIb, elevated high-sensitivity C-reactive protein (hs-CRP) level, and dilation of ascending aorta and aortic root were statistically associated with aortic valvular lesion in TAK patients (OR [95%CI] 6.853 [1.685–27.875], p=0.007; 4.896 [1.646–14.561], p=0.004; 4.509 [1.517–13.403], p=0.007; 9.340 [2.188–39.875], p=0.003). The 1-, 5-, and 7-year cumulative incidence of postoperative adverse events were 14.7%, 14.7%, and 31.8%, respectively. Surgical methods (p=0.024, hazard ratio (HR) 0.082) and postoperatively anti-inflammatory therapy (p=0.036, HR 0.144) were identified as potential predictors of postoperative adverse events.

Conclusions

Regularly echocardiogram screening is suggested in patients with Numano type IIb and aggressive treatment should be performed early in TAK patients. As for TAK patients with aortic valve surgery, aortic root replacement seems to be the preferred option and regular anti-inflammatory therapy may reduce the occurrence of adverse events of them.

Novel Therapies in Takayasu Arteritis

Takayasu Arteritis (TAK) is a large-vessel vasculitis that preferentially involves the aorta and its primary branches. Cardiac involvement is frequent in TAK and is a major determinant of the patient's outcome. Glucocorticoids (GC) are the mainstay of therapy for TAK, with high doses of GC effective to induce remission. However, relapses are common and lead to repeated and prolonged GC treatments with high risk of related adverse events. Potential GC toxicity is a major concern, especially because patients with TAK are young and need to be treated for several years, often for the whole life. Conventional immunosuppressive drugs are used in patients with severe manifestations but present some limitations. New therapeutic approaches are needed for patients with refractory disease or contraindications to conventional therapies. Fortunately, major progress has been made in understanding TAK pathogenesis, leading to the development of targeted biotherapies. In particular, IL-6 and TNF-α pathways seems to be the most promising therapeutic targets, with emerging data on Tocilizumab and TNF inhibitors. On the other hand, new insights on JAK-Inhibitors, Rituximab, Ustekinumab and Abatacept have been explored in recent studies. This review summarizes the emerging therapies used in TAK, focusing on the most recent studies on biologics and analyzing their efficacy and safety.

Physical Exercise in Managing Takayasu Arteritis Patients Complicated With Cardiovascular Diseases

Takayasu arteritis (TA) is a kind of large-vessel vasculitis that mainly affects the aorta and its branches, and the patients are usually women at a relatively young age. The chronic inflammation of arteries in TA patients leads to stenosis, occlusion, dilatation, or aneurysm formation. Patients with TA thereby have a high risk of cardiovascular disease (CVD) complications, which are the most common cause of mortality. This review summarizes the main cardiovascular complications and the risk factors of cardiovascular complications in patients with TA. Here, we discuss the benefits and potential risks of physical exercise in patients with TA and give recommendations about exercise prescription for TA patients to decrease the risks of CVD and facilitate rehabilitation of cardiovascular complications, which might maximally improve the outcomes.

Clinical characteristics and outcomes of chronic heart failure in adult Takayasu arteritis: A cohort study of 163 patients

BACKGROUND

Chronic heart failure (CHF) is a serious complication and a major cause of mortality in patients with Takayasu arteritis (TA). We aimed to explore the clinical features and long-term outcomes in TA patients with CHF.

METHODS AND RESULTS

Adult TA patients admitted to our hospital between January 2009 to April 2018 were classified as HF and non-HF group. The adverse events were defined as a composite of all-cause mortality and hospitalization for HF. The outcome of the HF-group was further analyzed. A total of 61 HF patients and 102 non-HF patients were identified. In the HF group, the median age at assessment was 41.9 years, and female was predominant (82.0%). The multivariable logistic regression model revealed that pulmonary hypertension, aortic regurgitation, mitral regurgitation, level albumin, and uric acid were independently associated with CHF. After a median follow-up of 1347 days, 25 adverse events occurred in HF patients, and the 5-year event-free rate was 54.7%. The Cox model showed that coronary artery involvement, aortic regurgitation, without interventional treatment were related to adverse events.

CONCLUSIONS

The 5-year event-free rate was not satisfying. Aggressive intervention may decreased the likelihood of adverse events in patients with CHF.

Cardiac involvement in the adult primary vasculitides

INTRODUCTION

Heart involvement in vasculitis is rare, but potentially severe. The ascertainment of cardiac disease in vasculitis is complex and requires an integrated multidisciplinary approach involving the Rheumatologist, Radiologist, Cardiologist, and Heart surgeon.

AREAS COVERED

the authors searched PubMed using the keywords 'heart'[Mesh] and vasculitis"[Mesh].

EXPERT OPINION

Virtually any vasculitis can affect the heart, but cardiac involvement is more common in some vasculitides such as Takayasu arteritis, polyarteritis nodosa, and eosinophilic granulomatosis with polyangiitis. Immunosuppressive treatment and when indicated surgery can improve the prognosis.

Elevated antistreptolysin O titer is closely related to cardiac mitral insufficiency in untreated patients with Takayasu arteritis

Background

The etiology of Takayasu arteritis (TA) is unknown; however, a possible relationship between streptococcal infection and TA has been proposed. This study aimed to identify the clinical features and cardiac valvular involvement in untreated TA patients with an elevated antistreptolysin O (ASO) titer.

Methods

In this retrospective study, the clinical characteristics and features of valvular involvement were compared in TA patients with or without an elevated ASO titer.

Results

Of the 74 untreated TA patients, 13 patients were found have elevated ASO titers (17.6%). Mitral insufficiency was the most common in patients with elevated ASO (69.2%, 9/13), followed by aortic valve insufficiency (46.2%, 5/13) and tricuspid insufficiency (46.2%, 5/13), which were no significantly different than that in normal ASO group. The proportions of moderate to severe mitral (30.8% vs 1.6%, p = 0.000) and tricuspid valve (15.4% vs 1.64%, p = 0.023) insufficiency in the ASO positive group were significantly higher than those in the ASO negative group. The odds of mitral regurgitation in patients with elevated ASO titers were 3.9 times higher than those in the group with normal ASO titers (p = 0.053, OR = 3.929, 95% confidence interval [CI]: 0.983–15.694). Furthermore, the risk of moderate to severe mitral insufficiency in patients with elevated ASO titers was 41.6 times higher than that in patients with normal ASO titers (p = 0.002, OR = 41.600, 95% CI: 3.867–447.559).

Conclusions

An increase in ASO titer is related to valvular involvement in TA and is closely linked to mitral insufficiency.

Surgical Treatment in Patients With Aortic Regurgitation Due to Takayasu Arteritis

BACKGROUND

Aortic regurgitation is a common complication in patients with Takayasu arteritis. Severe aortic regurgitation requires surgical treatment. We investigated the outcomes of aortic valve replacement (AVR) and composite graft replacement (CGR) in patients with Takayasu arteritis and aortic regurgitation.

METHODS

We retrospectively reviewed the data from 41 patients with Takayasu arteritis and aortic regurgitation treated by AVR (n = 23) and CGR (n = 18) from January 1992 to December 2016.

RESULTS

The mean age at operation was 40.3 years, and 61.0% were women. Concurrent procedures were performed in 43.9% of patients. The preoperative aortic root diameter in the AVR and CGR groups was 41.5 ± 7.9 and 47.8 ± 9.5 mm, respectively. The cardiopulmonary bypass time was longer in the CGR group (140.2 ± 44.8 minutes) than in the AVR group (105.2 ± 32.5 minutes). No in-hospital death occurred. During a median follow-up of 6.6 years (interquartile range, 0.6-9.4) we observed 10 patients with composite adverse events in the AVR group (1 death, 3 reoperations, 3 residual ascending aorta aneurysms, 6 paravalvular leaks, and 1 valve detachment) and 2 composite events in the CGR group (2 deaths and 1 paravalvular leak). The unadjusted 5-year event-free rate was 55.8% and 91.7% in the AVR and CGR groups, respectively (log-rank P < .05). CGR was associated with nominally lower events on adjusted analysis (hazard ratio, 4.212; 95% confidence interval [0.910, 19.509]; P = .066).

CONCLUSIONS

Paravalvular leak was the main postoperative complication. CGR was associated with nominally fewer adverse events.
