Magnetic Resonance in Transthyretin Cardiac Amyloidosis.

Aims Wild-type transthyretin amyloidosis (ATTRwt) is mostly considered a disease predominantly of elderly male, characterized by concentric LV hypertrophy, preserved LVEF, and low QRS voltages. We sought to describe the characteristics of a large cohort of ATTRwt patients to better define the disease. Methods and results Clinical findings of consecutive ATTRwt patients diagnosed at 2 centres were reviewed. ATTRwt was diagnosed histologically or non-invasively (LV hypertrophy ≥12 mm, intense cardiac uptake at 99mTc-DPD scintigraphy and AL exclusion). Mutations in TTR were excluded in all cases. The study cohort comprised 108 patients (78.6 ± 8 years); 67 (62%) diagnosed invasively and 41 (38%) non-invasively. Twenty patients (19%) were females. An asymmetric hypertrophy pattern was observed in 25 (23%) patients. Mean LVEF was 52 ± 14%, with 39 patients (37%) showing a LVEF < 50%. Atrial fibrillation (56%) and a pseudo-infarct pattern (63%) were the commonest ECG findings. Only 22 patients fulfilled QRS low-voltage criteria while 10 showed LV hypertrophy on ECG. Although heart failure was the most frequent profile leading to diagnosis (68%), 7% of individuals presented with atrioventricular block and 11% were diagnosed incidentally. Almost one third (35; 32%) were previously misdiagnosed. Conclusion The clinical spectrum of ATTRwt is heterogeneous and differs from the classic phenotype: women are affected in a significant proportion; asymmetric LV hypertrophy and impaired LVEF are not rare and only a minority have low QRS voltages. Clinicians should be aware of the broad clinical spectrum of ATTRwt to correctly identify an entity for which a number of disease-modifying treatments are under investigation.

Clinical characteristics of wild-type transthyretin cardiac amyloidosis: disproving myths.

Cardiovascular (CV) imaging is an important tool in baseline risk assessment and detection of CV disease in oncology patients receiving cardiotoxic cancer therapies. This position statement examines the role of echocardiography, cardiac magnetic resonance, nuclear cardiac imaging and computed tomography in the management of cancer patients. The Imaging and Cardio-Oncology Study Groups of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) in collaboration with the European Association of Cardiovascular Imaging (EACVI) and the Cardio-Oncology Council of the ESC have evaluated the current evidence for the value of modern CV imaging in the cardio-oncology field. The most relevant echocardiographic parameters, including global longitudinal strain and three-dimensional ejection fraction, are proposed. The protocol for baseline pre-treatment evaluation and specific surveillance algorithms or pathways for anthracycline chemotherapy, HER2-targeted therapies such as trastuzumab, vascular endothelial growth factor tyrosine kinase inhibitors, BCr-Abl tyrosine kinase inhibitors, proteasome inhibitors and immune checkpoint inhibitors are presented. The indications for CV imaging after completion of oncology treatment are considered. The typical consequences of radiation therapy and the possibility of their identification in the long term are also summarized. Special populations are discussed including female survivors planning pregnancy, patients with carcinoid disease, patients with cardiac tumours and patients with right heart failure. Future directions and ongoing CV imaging research in cardio-oncology are discussed.

Echo Parameters for Differential Diagnosis in Cardiac Amyloidosis: A Head-to-Head Comparison of Deformation and Nondeformation Parameters.

Over the past few decades, advances in pharmacological, catheter-based, and surgical reperfusion have improved outcomes for patients with acute myocardial infarctions. However, patients with large infarcts or those who do not receive timely revascularization remain at risk for mechanical complications of acute myocardial infarction. The most commonly encountered mechanical complications are acute mitral regurgitation secondary to papillary muscle rupture, ventricular septal defect, pseudoaneurysm, and free wall rupture; each complication is associated with a significant risk of morbidity, mortality, and hospital resource utilization. The care for patients with mechanical complications is complex and requires a multidisciplinary collaboration for prompt recognition, diagnosis, hemodynamic stabilization, and decision support to assist patients and families in the selection of definitive therapies or palliation. However, because of the relatively small number of high-quality studies that exist to guide clinical practice, there is significant variability in care that mainly depends on local expertise and available resources.

Mechanical Complications of Acute Myocardial Infarction: A Scientific Statement From the American Heart Association.

Background Cardiac amyloidosis (CA) is associated with typical morphological features on echocardiography, including concentric LV hypertrophy (LVH). Cardiac magnetic resonance (CMR) can accurately depict anatomy in different cardiomyopathies. Our aim was to describe the morphological features and remodelling patterns of CA with CMR, and establish their diagnostic accuracy, as well as the value of traditional diagnostic criteria derived from echocardiography and electrocardiography. Methods Consecutive patients referred for CMR for possible CA were retrospectively evaluated. The diagnosis of CA was established in the presence of a positive cardiac biopsy and/or a typical pattern of myocardial late gadolinium enhancement. Morphological parameters were obtained from standard cine sequences. The presence and distribution of LVH, relative wall thickness (RWT) and LV remodelling patterns were determined. Results 130 patients (92 males (70.8%), age 64±13 years) were included. CA was diagnosed in 51 (39.2%). Patients with CA had increased LV wall thickness and LV mass index. An LV remodelling pattern different from concentric LVH was found in 42% of patients with CA, and asymmetric LVH was noted in 68.6%. A model including RWT, asymmetric LVH, and LVMI showed diagnostic accuracy of 88%, sensitivity of 67% and specificity of 86% for CA detection. Traditional diagnostic criteria for CA showed high specificity but poor sensitivity. Conclusions Asymmetric LVH and remodelling patterns different from concentric LVH are common in CA. Increased LV mass index, increased RWT, and asymmetric LVH are independently associated with the diagnosis. Traditional diagnostic criteria show poor sensitivity.

Cardiac magnetic resonance evaluation of left ventricular remodelling distribution in cardiac amyloidosis

Palliative care in the cardiac intensive care unit

Finding Purpose as Fellows: Opportunities Through Organization

Patients admitted to today's cardiac intensive care units (CICUs) have increasingly complex medical conditions; consequently, palliative care is becoming an integral component of their care. Although there is a robust body of literature emanating from other intensive care unit settings, there has been less discussion about the role of palliative care in the CICU. This study examined all admissions to the Mount Sinai Hospital CICU from January 1 through December 31, 2012. Of the 1,368 patients admitted, there were 117 CICU patient deaths. End-of-life discussions were carried out in 85 patients (72.6%) who died during that hospital admission; the primary CICU team led these discussions and helped with decision making in >1/2 of them. For the 85 patients who had goals of care (GOC) discussions, there was a higher rate of redirected GOC toward comfort care or no escalation of care (38.8% vs 3.1%, p
