Abstract
The diagnosis and awareness of transthyretin amyloidosis cardiomyopathy (ATTR-CM) in heart failure with left ventricular ejection fraction (LVEF) > 40% remains under-recognized. This study aimed to investigate the prevalence and characteristics of ATTR-CM in patients with heart failure with LVEF > 40%. Patients with LVEF > 40% and maximal left ventricular wall thickness (MWT) > 10 mm who underwent bone scintigraphy were retrospectively investigated. Patients with a definite cause of heart failure were excluded. ATTR-CM was diagnosed when grade 2 or 3 myocardial uptake was observed on scintigraphy. Among 97 patients (male, 62.5%; median age, 69 years), 13 (13.4%) were diagnosed with ATTR-CM (wild type, 69.2%; hereditary type, 30.8%). Age or biomarker levels did not differ significantly; however, all patients with ATTR-CM were male. The ATTR-CM group had a significantly higher prevalence of polyneuropathy or carpal tunnel syndrome than the non-ATTR-CM group, accompanied by a longer PR interval, thicker MWT, larger left atrial volume index, and higher E/e'. Accordingly, ATTR was present in a substantial number, particularly among men. Clinicians should suspect ATTR when a male patient exhibits neurologic symptoms, diastolic dysfunction, and a long PR interval.

Atrial fibrillation in the setting of cardiac amyloidosis - A review of the literature. J Cardiol 2024; 84:155-160.

Abstract
Cardiac amyloidosis (CA) is related to the aggregation of insoluble fibrous deposits of misfolded proteins within the myocardium. Transthyretin amyloidosis (ATTR) and immunoglobulin light-chain amyloidosis are the main forms of CA. Atrial fibrillation (AF) is a common arrhythmia in CA patients, especially in those with ATTR amyloidosis. Increased atrial preload and afterload, atrial enlargement, enhanced atrial wall stress, and autonomic dysfunction are the main mechanisms of AF in CA patients. CA is associated with the formation of endocardial thrombi and systemic embolism. The promoters of thrombogenesis include endomyocardial damage, blood stasis, and hypercoagulability. The prevalence of thrombi in patients with AF remains elevated despite long-term anticoagulation. Consequently, transesophageal ultrasound examinations before cardioversion should be performed to exclude endocardiac thrombi despite anticoagulation. Furthermore, the CHA2DS2-VASc score should not be used to assess the thromboembolic risk in CA patients with AF. Rate control is challenging in patients with CA, while rhythm control is the preferred treatment option, especially in the early stages of the disease process. Although catheter ablation is an effective treatment option, more data are needed to explore the role of the procedure in CA patients.

Abstract
Atrial myopathy is a condition that consists of electrical, structural, contractile, and autonomic remodeling of the atria and is the substrate for development of atrial fibrillation, the most common arrhythmia. Pathophysiologic mechanisms driving atrial myopathy are inflammation, oxidative stress, atrial stretch, and neurohormonal signals, e.g., angiotensin-II and aldosterone. These mechanisms initiate the structural and functional remodeling of the atrial myocardium. Novel therapeutic strategies are being developed that target the pathophysiologic mechanisms of atrial myopathy. In this review, we will discuss the pathophysiology of atrial myopathy, as well as diagnostic and therapeutic strategies.

Abstract
Patients with heart failure with preserved ejection fraction (HFpEF) and atrial fibrillation (AF) have increased mortality and increased risk of stroke. Due to the heterogeneous nature of both disease processes, it is difficult to ascertain whether the diagnosis and progression of AF is the cause of deterioration or if it is a symptom of worsening heart failure. This presents physicians with a clinical conundrum of whether optimizing their heart failure will decrease the overall AF burden or if restoration of sinus rhythm is necessary to optimize patients with HFpEF. In this paper, we will review the impact of AF in patients with HFpEF, the pathophysiology and heterogeneity of HFpEF and AF, and the management of these patients. As HFpEF and AF become more prevalent, managing these disease processes needs standardization to improve outcomes. Further research is needed to understand the complex interplay between AF and HFpEF to help determine the best management strategy.

Abstract
Cardiac amyloidosis (CA) is now recognized as an important cause of heart failure. Increased wall thickness and diastolic dysfunction of the left ventricle are the most easily detectable manifestations of CA, but amyloid accumulates in all cardiac structures. Involvement of the left and right atria may be due to the haemodynamic effects of ventricular diastolic dysfunction, the effects of amyloid infiltration into the atrial wall, and the cardiotoxic damage of atrial cardiomyocytes by amyloid precursors. Atrial amyloidosis is an early manifestation of CA, and is associated with an increased risk of atrial fibrillation and thromboembolic events. Furthermore, atrial amyloidosis can be found even in the absence of systemic disease and ventricular involvement. This condition is named isolated atrial amyloidosis and is due to a local overproduction of atrial natriuretic peptide. In this review we summarize the evidence on the mechanisms and clinical relevance of atrial amyloidosis.

Abstract
Transthyretin amyloid cardiomyopathy (ATTR-CM) is a life-threatening infiltrative disease in elderly patients. Atrial arrhythmias (AAr) are common in patients with ATTR-CM. However, AAr treatment in these patients is challenging. In this case, a patient diagnosed with wild-type ATTR-CM suffered atrial fibrillation (AF) for ~1 year, according to the data of his self-monitoring and regular electrocardiogram. This AF reverted to normal sinus rhythm a few months after the initiation of tafamidis without administering an antiarrhythmic drug. Tafamidis may be beneficial as alternative antiarrhythmic therapy in patients with ATTR-CM.

Abstract
Transthyretin amyloid cardiomyopathy (ATTR‐CM) is caused by the cardiac deposition of insoluble amyloid fibrils formed by misfolded transthyretin proteins and is associated with various cardiac symptoms, such as progressive heart failure, conduction disturbance, and arrhythmia. The implementation of 99mtechnetium (99mTc)‐labelled bone radiotracer scintigraphy for diagnosing ATTR‐CM has enabled accurate diagnosis of the disease with high sensitivity and specificity and positioned this diagnostic modality as an integral part of disease diagnostic algorithms. In 2020, 99mTc‐pyrophosphate scintigraphy received exceptional approval for Japanese national health insurance reimbursement as a diagnostic method of ATTR‐CM. Nevertheless, the utility of 99mTc‐labelled bone radiotracer scintigraphy and the importance of an early diagnosis of suspected ATTR‐CM using this technique have yet to be internalized as common practice by general cardiologists, and guidance on daily clinical scenarios to consider this technique for a diagnosis of suspected ATTR‐CM is warranted. In this review, we discuss the utility of 99mTc‐labelled bone radiotracer scintigraphy for the early diagnosis of ATTR‐CM based on published literature and the outcomes of an advisory board meeting. This review also discusses clinical scenarios that could support early diagnosis of suspected ATTR‐CM as well as common pitfalls, correct implementation, and future perspectives of 99mTc‐labelled bone radiotracer scintigraphy in daily clinical practice. The clinical scenarios to consider 99mTc‐labelled bone radiotracer scintigraphy in daily practice may include, but are not limited to, patients with a family history of the hereditary type of disease; elderly patients (aged ≥60 years) with unexplained cardiac findings (e.g. cardiac hypertrophy associated with abnormalities on an electrocardiogram, heart failure with preserved ejection fraction associated with unexplained left ventricular hypertrophy, and heart failure with reduced ejection fraction associated with atrial fibrillation and left ventricular hypertrophy); and patients with cardiac hypertrophy associated with diastolic dysfunction, right ventricular/interatrial septum/valve thickness, left ventricular sparkling, or apical sparing. Cardiac hypertrophy and persistent elevation in cardiac troponin in elderly patients are also suggestive of ATTR‐CM. 99mTc‐labelled bone radiotracer scintigraphy is also recommended in patients with characteristic cardiac magnetic resonance findings (e.g. diffuse subendocardial late gadolinium enhancement patterns, native T1 increase, and increase in extracellular volume) or patients with cardiac hypertrophy and bilateral carpal tunnel syndrome.

Abstract
Cardiac amyloidosis, once considered a rare disease, has garnered significant attention over the last few years due to three key reasons: first, increased recognition of this disease in conjunction with various common cardiac conditions such as heart failure with preserved ejection fraction and aortic stenosis; second, due to the advent of promising new therapies for light chain disease (AL), transthyretin (ATTR) cardiomyopathy, and amyloid neuropathy; finally, the advancements in cardiac imaging including echocardiography, magnetic resonance imaging, and nuclear cardiac scintigraphy aid in non-biopsy diagnosis of ATTR cardiac amyloidosis. The hereditary forms of ATTR have further come into importance with the availability of genetic testing and increased prevalence of certain mutations in African Americans. Recognition of non-cardiac clues to this disease has gained importance and reiterates that high clinical suspicion, detailed patient history, and examination with appropriate use of imaging are vital to confirm the diagnosis.

Abstract
Amyloidosis is a systemic illness that affects multiple organ systems, including the cardiovascular, renal, gastrointestinal, and pulmonary systems. Common manifestations include restrictive cardiomyopathy, arrhythmias, nephrotic syndrome, and gastrointestinal hemorrhage. It is unknown whether coexisting atrial fibrillation (AF) worsens the disease burden and outcomes in patients with systemic amyloidosis. In this study, those with a diagnosis of amyloidosis with and without coexisting AF were identified by querying the Healthcare Cost and Utilization Project—specifically, the National Inpatient Sample for the year 2016—based on International Classification of Diseases, 10th Revision, Clinical Modification codes. During 2016, a total of 2,997 patients were admitted with a diagnosis of amyloidosis, including 918 with concurrent AF. Greater rates of mortality (7.4% vs. 5.6%); heart block (6.8% vs. 2.8%); cardiogenic shock (5% vs. 1.6%); placement of an implantable cardioverter-defibrillator, cardiac resynchronization therapy device, or permanent pacemaker (14.5% vs. 4.5%); renal failure (29% vs. 21%); heart failure (66% vs. 30%); and bleeding complications (5.7% vs. 2.8%) were observed in patients with a diagnosis of amyloidosis and coexisting AF when compared with in patients without AF. Interestingly, patients with amyloidosis without comorbid AF had greater odds of associated stroke relative to those with concurrent AF (7.9% vs. 3.4%).

Abstract
Telocytes are interstitial cells with long, thin processes by which they contact each other and form a network in the interstitium. Myocardial remodeling of adult patients with different forms of atrial fibrillation (AF) occurs with an increase in fibrosis, age-related isolated atrial amyloidosis (IAA), cardiomyocyte hypertrophy and myolysis. This study aimed to determine the ultrastructural and immunohistochemical features of cardiac telocytes in patients with AF and AF + IAA. IAA associated with accumulation of atrial natriuretic factor was detected in 4.3-25% biopsies of left (LAA) and 21.7-41.7% of right (RAA) atrial appendage myocardium. Telocytes were identified at ultrastructural level more often in AF + IAA, than in AF group and correlated with AF duration and mitral valve regurgitation. Telocytes had ultrastructural signs of synthetic, proliferative, and phagocytic activity. Telocytes corresponded to CD117+, vimentin+, CD34+, CD44+, CD68+, CD16+, S100-, CD105- immunophenotype. No significant differences in telocytes morphology and immunophenotype were found in patients with various forms of AF. CD68-positive cells were detected more often in AF + IAA than AF group. We assume that in aged AF + IAA patients remodeling of atrial myocardium provoked transformation of telocytes into "transitional forms" combining the morphological and immunohistochemical features with signs of fibroblast-, histiocyte- and endotheliocyte-like cells.

Abstract
Background Atrial fibrillation(AF) is as an abnormal irregular rhythm with chaotic generation of electrical signals in the atria of the heart. Various studies in the West have proved that atrial substrates, like isolated atrial amyloidosis can trigger the development of atrial fibrillation. In India, these structural changes have been analyzed on autopsied hearts. Aim To determine the role of Atrial Amyloid as a substrate for Atrial fibrillation in ante mortem hearts. Methods and Results Atrial appendages were obtained from seventy five patients undergoing open heart surgery at a tertiary care hospital in south India. They were stained with Hematoxylin &Eosin, Masson's Trichrome and Congo red stains and were examined for myocarditis, fibrosis and amyloidosis, respectively. 30 (40%) patients were in AF. Amyloid deposits were seen in 3 cases. All the three were in AF and had undergone mitral valve replacement (MVR) (P<0.05). 2 out of the 3 amyloid-positive cases showed active myocarditis and severe scarring but there was no statistically significant correlation between these factors. Conclusion Amyloid and myocarditis, independently act as an arrythmogenic substrates in the development of atrial fibrillation and are also increasingly associated with female gender and MVR. We hypothesize that the amyloid deposits are due to isolated atrial amyloidosis as they were seen only in young individuals. Some patients in sinus rhythm (SR) had large left atria and myocarditis and probably are at a higher risk for developing AF. Hence, follow-up of these patients is required for prevention of severe organ damage and timely therapeutic intervention.
