Heart failure (HF) is a progressive disease. It is estimated that more than 250,000 patients suffer from advanced HF with reduced ejection fraction refractory to medical therapy. With limited donor pool for heart transplant, continue flow left ventricle assist device (LVAD) is a lifesaving treatment option for patients with advanced HF. This review will provide an update on indications, contraindications, and associated adverse events for LVAD support with a summary of the current outcomes data.

Cardiogenic shock is a multisystem pathology that carries a high mortality rate, and initial pharmacotherapies include the use of vasopressors and inotropes. These agents can increase myocardial oxygen consumption and decrease tissue perfusion that can oftentimes result in a state of refractory cardiogenic shock for which temporary mechanical circulatory support can be considered. Numerous support devices are available, each with its own hemodynamic blueprint. Defining a patient's hemodynamic profile and understanding the phenotype of cardiogenic shock is important in device selection...

Transcatheter mitral valve repair should be considered for patients with severe secondary mitral regurgitation with symptomatic heart failure with reduced ejection fraction for symptom improvement and survival benefit. Patients with a higher severity of secondary mitral regurgitation relative to the degree of left ventricular dilation are more likely to benefit from transcatheter mitral valve repair. A multidisciplinary Heart Team should participate in patient selection for transcatheter mitral valve therapy...

Successful remote patient monitoring depends on bidirectional interaction between patients and multidisciplinary clinical teams. Invasive pulmonary artery pressure monitoring has been shown to reduce heart failure (HF) hospitalizations, facilitate guideline-directed medical therapy optimization, and improve quality of life. Cardiac implantable electronic device-based multiparameter monitoring has shown encouraging results in predicting future HF-related events. Potential expanded indications for remote monitoring include guideline-directed medical therapy optimization, application to specific populations, and subclinical detection of HF...

Life-threatening dysrhythmias remain a significant cause of mortality in patients with nonischemic cardiomyopathy (NICM). Implantable cardioverter-defibrillators (ICD) effectively reduce mortality in patients who have survived a life-threatening arrhythmic event. The evidence for survival benefit of primary prevention ICD for patients with high-risk NICM on guideline-directed medical therapy is not as robust, with efficacy questioned by recent studies. In this review, we summarize the data on the risk of life-threatening arrhythmias in NICM, the recommendations, and the evidence supporting the efficacy of primary prevention ICD, and highlight tools that may improve the identification of patients who could benefit from primary prevention ICD implantation...

Obesity has been long recognized as a risk factor for the development of heart failure, but recent evidence suggests obesity is more typically associated with heart failure with preserved ejection fraction as opposed to heart failure with reduced ejection fraction (HFrEF). Nevertheless, numerous studies have found that obesity modulates the presentation and progression of HFrEF and may contribute to the development of HFrEF in some patients. Although obesity has definite negative effects in HFrEF patients, the effects of intentional weight loss in HFrEF patients with obesity have been poorly studied...

Frailty affects half of all patients with heart failure with reduced ejection fraction (HFrEF) and carries a ∼2-fold increased risk of mortality. The relationship between frailty and HFrEF is bidirectional, with one condition exacerbating the other. Paradoxical to their higher clinical risk, frail patients with HFrEF are more often under-treated due to concerns over medication-related adverse clinical events. However, current evidence suggests consistent safety of HF medical therapies among older frail patients with HFrEF...

The conventional sequence of guideline-directed medical therapy (GDMT) initiation in heart failure with reduced ejection fraction (HFrEF) assumes that the effectiveness and tolerability of GDMT agents mirror their order of discovery, which is not true. In this review, the authors discuss flexible GDMT sequencing that should be permitted in special populations, such as patients with bradycardia, chronic kidney disease, or atrial fibrillation. Moreover, the initiation of certain GDMT medications may enable tolerance of other GDMT medications...

Treatment of heart failure with reduced ejection fraction (HFrEF) has benefitted from a proliferation of new medications and devices. These treatments carry important clinical benefits, but also come with costs relevant to payers, providers, and patients. Patient out-of-pocket costs have been implicated in the avoidance of medical care, nonadherence to medications, and the exacerbation of health care disparities. In the absence of major health care policy and payment redesign, high-quality HFrEF care delivery requires transparent integration of cost considerations into system design, patient-clinician interactions, and medical decision making...

Minoritized racial and ethnic groups have the highest incidence, prevalence, and hospitalization rate for heart failure. Despite improvement in medical therapies and overall survival, the morbidity and mortality of these groups remain elevated. The reasons for this disparity are multifactorial, including social determinant of health (SDOH) such as access to care, bias, and structural racism. These same factors contributed to higher rates of COVID-19 infection among minoritized racial and ethnic groups. In this review, we aim to explore the lessons learned from the COVID-19 pandemic and its interconnection between heart failure and SDOH...

Transthyretin amyloid cardiomyopathy (ATTR-CM) is a relatively prevalent cause of morbidity and mortality. Over the recent years, development of disease-modifying treatments has enabled stabilization of the circulating transthyretin tetramer and suppression of its hepatic production, resulting in a remarkable improvement in survival of patients with ATTR-CM. Second-generation drugs for silencing are currently under investigation in randomized clinical trials. In vivo gene editing of transthyretin has been achieving unanticipated suppression of hepatic production in ATTR-CM...

Transthyretin amyloid cardiomyopathy (ATTR-CM) is caused by the myocardial extracellular deposition of amyloid fibrils formed from the dissociation of TTR tetramer into monomers. The rate-limiting step in TTR amyloidogenesis is the dissociation of the TTR tetramer into monomers: Tafamidis is an effective TTR-stabilizer in its native homotetrameric structure. Tafamidis is a safe and effective drug in reducing symptoms, hospitalization and mortality in accurately selected patients affected by hereditary and wild-type transthyretin amyloid cardiomyopathy...

Amyloidosis is a systemic disease due to the accumulation of misfolded amyloid fibrils that damage the heart and worsen the prognosis. Heart failure (HF), a condition frequently linked with an advanced stage of this disease, is the most prevalent clinical manifestation that leads to its diagnosis. However, due to the growing awareness of the occurrence of cardiac amyloidosis (CA), it is now possible to perform an early diagnosis and have a positive impact on its natural course. This study aims to highlight the most compelling issues concerning patients' clinical management with HF and CA...

Hereditary transthyretin-related amyloidosis (hATTR) is the most common form of familial amyloidosis. It is an autosomal dominant disease caused by a pathogenic variant in the TTR gene. More than 140 TTR gene variants have been associated with hATTR, with the Val30Met variant representing the most common worldwide. The clinical phenotype varies according to the gene variant and includes predominantly cardiac, predominantly neurologic, and mixed phenotypes. The present review aims to describe the genotype-phenotype correlations in hATTR...

Cardiac amyloidosis (CA) is caused by the myocardial deposition of misfolded proteins, either amyloid transthyretin (ATTR) or immunoglobulin light chains (AL). The paradigm of this condition has transformed, since CA is increasingly recognized as a relatively prevalent cause of heart failure. Cardiac scintigraphy with bone tracers is the unique noninvasive technique able to confirm CA without performing tissue biopsy or advanced imaging tests. A moderate-to-intense myocardial uptake (Perugini grade ≥2) associated with the absence of a monoclonal component is greater than 99% specific for ATTR-CA, while AL-CA confirmation requires tissue biopsy...

Cardiac magnetic resonance represents the gold standard imaging technique to assess cardiac volumes, wall thickness, mass, and systolic function but also to provide noninvasive myocardial tissue characterization across almost all cardiac diseases. In patients with cardiac amyloidosis, increased wall thickness of all heart chambers, a mildly reduced ejection fraction and occasionally pleural and pericardial effusion are the characteristic morphologic anomalies. The typical pattern after contrast injection is represented by diffuse areas of late gadolinium enhancement, which can be focal and patchy in very early stages, circumferential, and subendocardial in intermediate stages or even diffuse transmural in more advanced stages...

Amyloidosis is a systemic condition characterized by multiple organs involvement. A multidisciplinary and multimodal approach in assessing patients is pivotal and recommended by the international scientific societies. Biomarkers represent an essential noninvasive tool to increase the suspicion of disease and orient further workup and clinical management of patients. This review provides an updated contemporary focus on the clinical use of biomarkers in cardiac amyloidosis, emphasizing their role in both the diagnostic and prognostic setting and discussing future perspective of emerging biomarkers...

Amyloidosis is a rare, heterogeneous group of diseases characterized by extracellular infiltration and deposition of misfolded fibrils in different organs and tissues. A timely diagnosis is important as it can improve outcome. Echocardiography has emerged as a powerful tool to prompt suspicion and refer patients to second-level evaluation to reach a definitive diagnosis. In this scenario, new echo techniques offer new insight into the cardiac amyloidosis (CA) pathophysiology and clinical course. The present review aims to describe the developments in echocardiographic assessment of patients with suspected CA and it summarizes new available echocardiographic scores able to guide a definite diagnosis...
