A 68 year-old man with a severe ischemic cardiomyopathy underwent left ventricular assist device (LVAD) implantation (Heart Mate II device) for destination therapy. He presented 49 months following LVAD implant with worsening heart failure symptoms and new severe aortic regurgitation. Given high risk for both surgical and transcatheter aortic valve replacement, he was admitted for transcatheter closure of the aortic valve under transesophageal echocardiographic (TEE) guidance. TEE imaging revealed severe aortic regurgitation (see Figure 1A and 1B, and multimedia files 1 and 2)...

BACKGROUND: Right ventricular (RV) function has recently gained attention as a prognostic predictor of outcome even in patients who have left-sided heart failure. Since several conventional echocardiographic parameters of RV systolic function have been proposed, our aim was to determine if any of these parameters (tricuspid annular plane systolic excursion: TAPSE, tissue Doppler derived systolic tricuspid annular motion velocity: S', fractional area change: FAC) are associated with outcome in advanced heart failure patients with dilated cardiomyopathy (DCM)...

Ventricular tachycardia (VT) is common in cardiomyopathy patients with an implantable cardioverter-defibrillator. This analysis evaluated antiarrhythmic medication use and change in use over time in patients with VT and structural heart disease. Query of Medicare claims identified patients with an implantable cardioverter-defibrillator and VT. Patients with atrial fibrillation or supraventricular tachycardia were excluded. Two cohorts were created of patients enrolled in Medicare Part D for the 12 months before 2007 and 2012...

BACKGROUND: The relations of elevated N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and cardiac ischemia in hypertrophic cardiomyopathy (HCM) patients is uncertain. Therefore we designed the study with the following aims: (1) to analyze plasma concentrations of NT-pro-BNP in various subsets of HCM patients; (2) to reveal the correlations of NT-pro-BNP, myocardial ischemia, and diastolic dysfunction; (3) to assess predictors of the elevated plasma levels of NT-pro-BNP. METHODS AND RESULTS: In 61 patients (mean age 48...

OBJECTIVES: This is an early feasibility clinical test of mitral loop cerclage annuloplasty to treat secondary mitral valve regurgitation. BACKGROUND: Secondary mitral regurgitation is characterized by cardiomyopathy, mitral annular enlargement, and leaflet traction contributing to malcoaptation. Transcatheter mitral loop cerclage applies circumferential compression to the mitral annulus by creating a loop through the coronary sinus across the interventricular septum, protecting entrapped coronary arteries from compression, and interactive annular reduction under echocardiographic guidance...

BACKGROUND: Transthyretin (TTR) amyloidosis is a hereditary disease with a complex genotype-phenotype correlation. We conducted a literature survey to define the clinical landscape of TTR amyloidosis across populations worldwide. Then, we investigated whether the genetically determined TTR expression differs among human populations, contributing to the differences observed in patients. Polygenic scores for genetically determined TTR expression in 14 clinically relevant tissues were constructed using data from the GTEx (Genotype-Tissue Expression) project and tested in the samples from the 1,000 Genomes Project...

OBJECTIVES: Atrial fibrillation (AF) is common in patients with hypertrophic cardiomyopathy (HCM) and it is often poorly tolerated because of loss of atrial contraction and reduced filling time with rapid ventricular rates. Restoring sinus rhythm is of great clinical benefit to HCM patients. Very few data exist regarding surgical ablation of concomitant AF in this setting. The aim of this study was to evaluate the mid-term outcome of surgical AF ablation in patients who underwent cardiac surgery due to HCM...

Diabetic foot ulcer (DFU) is one of the major complications of diabetes and about 1% of people with diabetes have to go for lower limb amputation. With better understanding of the pathological basis of DFU, number of biomarkers like atrial natriuretic peptides, galectin-3, and cardiac troponins for diabetic cardiomyopathy, cystatin C for diabetics nephropathy and C-reactive protein for infection and procalcitonin could aid in early and noninvasive diagnosis especially when clinical signs are misleading. Predictive role of novel biomarkers in primary prevention however, requires additional studies considering sex, age and multiple complications in DFU...

BACKGROUND: Takotsubo Cardiomyopathy (TTC) is a transient disorder of ventricular wall dysfunction, mostly induced by physical or emotional stress. TTC may be associated with adverse cardiac events. The association of cancer and its clinical impact in TTC patients has not been described yet. METHODS: In 114 consecutive patients presenting with TTC between January 2003 and September 2015, we studied the frequency of cancer diagnosis, and compared the clinical course and the occurrence of a clinical endpoint of cancer and non-cancer patients during a follow up of 4...

Persistent atrial standstill is a rare arrhythmia in both human and veterinary patients. In recent decades, cases of partial atrial standstill have been recognized in humans. We describe a case of presumptive partial atrial standstill in a Greyhound, in which there was disparate left and right atrial electromechanical function and rapid progression to congestive heart failure over the span of fourteen weeks. An atrial cardiomyopathy characterized by severe, diffuse, fibrofatty replacement of the atrial myocardium was identified histologically...

Cardiac muscle-related microRNAs play important roles in cardiac development and disease by translational silencing of mRNAs, the dominant mechanism of microRNA action. To test whether they could be involved in daunorubicin-associated cardiomyopathy (DACM), we determined expression patterns of myomiRs in two distinct models of DACM. We used 10-12 weeks old male Wistar rats. In the sub-acute model, rats were administered with six doses of daunorubicin (DAU-A, 3 mg/kg, i.p., every 48 h). Rats were sacrificed two days after the last dose...

Inflammatory dilated cardiomyopathy (DCMi) is a major cause of heart failure in children and young adults. DCMi develops in up to 30% of myocarditis patients, but the mechanisms involved in disease progression are poorly understood. Patients with eosinophilia frequently develop cardiomyopathies. In this study, we used the experimental autoimmune myocarditis (EAM) model to determine the role of eosinophils in myocarditis and DCMi. Eosinophils were dispensable for myocarditis induction but were required for progression to DCMi...

Coronary artery perforation during percutaneous intervention is a rare but potentially life threatening complication. The treatment of coronary perforation can be challenging in view of potential life threatening consequences such as cardiac tamponade or myocardial infarction. Presented is a clinical course of a 69year-old female who developed cardiac tamponade as a result of presumed wire related perforation of the posterolateral branch of the right coronary artery. Her clinical course was further complicated by recurrent tamponade, atrial fibrillation, stress induced cardiomyopathy, heparin induced thrombocytopenia and cardiogenic pulmonary edema...

BACKGROUND: With a high prevalence of coronary artery disease (CAD) among patients with atrial fibrillation (AF), CAD is one of the main risk factors for AF. However, little is known about the characteristics of CAD in AF patients. Especially, the question, whether a specific anatomical distribution of coronary artery stenoses might predispose to AF via atrial ischemia remains speculative. To address this issue, we evaluated potential associations between angiographic characteristics of CAD and AF...

BACKGROUND: Studies evaluating right ventricular (RV) structural and functional abnormalities in feline hypertrophic cardiomyopathy (HCM) are limited. HYPOTHESIS: Right ventricular structural and functional abnormalities are present in cats with HCM and are associated with clinical severity. ANIMALS: Eighty-one client-owned cats. METHODS: Retrospective 2-dimensional (2D) echocardiographic study. Right atrial diameter (RAD), RV free wall thickness (RVFWd), RV internal dimension (RVIDd), RV fractional area change (FAC), and tricuspid annular plane systolic excursion (TAPSE) were measured in control cats (n = 26), cats with subclinical HCM (subclinical HCM; n = 31), and cats with HCM and congestive heart failure (HCM + CHF; n = 24)...

Aditi Kalla, Vincent M Figueredo
There has been little focus on the effects of alcohol on the elderly. Although the cardiovascular benefits of moderate alcohol consumption could be of the greatest benefit in this group, so might be the detrimental effects of abuse. In this article, we review available data on the effects of alcohol consumption on cardiovascular disease, cardiomyopathy, arrhythmias, hypertension, and vascular function in older adults. Alcohol consumption has increased in the US population age 65 years and older in the last decade, as has monthly heavy episodic drinking in older alcohol consumers...

BACKGROUND: Subclinical left ventricular (LV) diastolic dysfunction in type 2 diabetes (T2D) is a common finding and represents an early sign of diabetic cardiomyopathy. However, the relationship between LV diastolic dysfunction and the incident T2D has not been previously studied. METHODS: A total of 1817 non-diabetic participants (mean age, 54 years; 48% men) from the Korean Genome and Epidemiology Study who were free of cardiovascular disease were studied. LV structure and function were assessed by conventional echocardiography and tissue Doppler imaging...

Atrial fibrillation is characterized by uncoordinated electrical activation of the atria that leads to the loss of atrial mechanical function and atrial fibrosis as a substrate promoting maintenance of rhythm abnormality. Transvenous electrical cardioversion has not been previously reported in the dog. The authors demonstrate the use of this technique for successful cardioversion of atrial fibrillation in two dogs with dilated cardiomyopathy.
