INTRODUCTION: Enhanced External Counter Pulsation (EECP) is a non-invasive treatment option for patients with Coronary Artery Disease (CAD). The treatment has shown to augment diastolic pressure and reduce Left Ventricular (LV) after-load by reducing systemic vascular resistance. The effect of EECP in standard brachial blood pressure and central haemodynamic parameters are not known. AIM: We hypothesized that EECP may have differential effect in CAD patients with low systolic blood pressure when compared to normal systolic pressure and the mechanism underlying this differential effect may be due to improvement in LV function...

Stress-induced cardiomyopathy (SIC), also known as takotsubo cardiomyopathy (TTC), is a relatively newly-described condition, which has been increasingly reported in the literature. It is characterized by acute onset of symptoms and electrocardiogram changes mimicking myocardial infarction, with transient but completely reversible left ventricular (LV) dysfunction. SIC commonly occurs following physical or emotional stress. The present study discusses the case of a 68-year-old female patient who had suffered from infection of the upper respiratory tract for 10 days before admission to the hospital with symptoms of chest stuffiness and dyspnea that persisted for 2 days...

BACKGROUND: The fate of the left ventricle (LV) after aortic valve replacement (AVR) in mixed aortic valve disease (MAVD) is unknown. METHODS: Patients with moderate-severe MAVD, ejection fraction ≥50%, and no coronary artery disease who underwent AVR were identified. Moderate-severe MAVD was defined as a combination of ≥moderate aortic stenosis and ≥moderate aortic regurgitation. Assessment for LVD was performed at 1 and 5years after AVR. The purpose of the study was to determine prevalence and predictors of early and late left ventricular dysfunction (LVD) defined as ejection fraction <50% at 1 and 5years post-AVR...

A 58-year-old man had been diagnosed with non-obstructive hypertrophic cardiomyopathy (HCMP) according to echocardiography findings 16 years ago. Echocardiography showed ischemic cardiomyopathy (CMP)-like features with decreased systolic function but a non-dilated chamber. Coronary angiography was performed but showed a normal coronary artery. Cardiac magnetic resonance imaging (MRI) revealed multifocal transmural and subepicardial delayed-enhancing areas at the anteroseptal, septal, and inferoseptal left ventricular (LV) wall, and wall thinning and decreased motion of the anteroseptal LV wall...

BACKGROUND: Although epicardial adipose tissue (EAT) volume is associated with increased incidence of coronary artery disease (CAD), its role in myocardial systolic dysfunction is unclear. The present study aimed to identify independent determinants of EAT volume in patients without obstructive CAD, and to evaluate the association between EAT volume (vs other measures of obesity) and myocardial systolic strain analysis. METHODS: We prospectively recruited 130 patients without obstructive CAD on contrast-enhanced cardiac computed tomography imaging and normal left ventricular ejection fraction on 3-dimensional (3D) echocardiography...

OBJECTIVE: Coronary slow-flow phenomenon (CSFP) is described as protracted passage of angiographic contrast agent to the distal portion of the epicardial coronary arteries in the absence of stenosis. Few studies have addressed the effects of this condition on right ventricular (RV) dysfunction. The present objective was to assess RV function in CSFP via 2-dimensional speckle-tracking echocardiography (2DSTE). METHODS: A total of 29 patients with CSFP and 29 participants with normal coronary flow were compared regarding RV systolic and diastolic functions...

REVIEW
Michael R Pinsky
The primary role of the right ventricle (RV) is to deliver all the blood it receives per beat into the pulmonary circulation without causing right atrial pressure to rise. To the extent that it also does not impede left ventricular (LV) filling, cardiac output responsiveness to increased metabolic demand is optimized. Since cardiac output is a function of metabolic demand of the body, during stress and exercise states the flow to the RV can vary widely. Also, instantaneous venous return varies widely for a constant cardiac output as ventilatory efforts alter the dynamic pressure gradient for venous return...

BACKGROUND: Left ventricular (LV) dysfunction after orthotopic heart transplantation (OHT) is multifactorial and can be an indicator of graft rejection or coronary artery vasculopathy. Analysis of rotational mechanics may help in the early diagnosis of ventricular dysfunction. Studies describing the left ventricular rotational strain in children after OHT are lacking. It is important to establish the baseline rotational mechanics in pediatric OHT to pursue further studies in this population...

Patients with cancer can present with difficult management issues, as the medicine can sometimes cause sequelae destructive to healthy tissue. As this population lives longer, cardiotoxic effects are beginning to emerge, but the early recognition of this signal can prove difficult, with too late a recognition leading to lifelong cardiac impairment and dysfunction. Cardio-oncology can bridge this difficulty, and echocardiography and its newer imaging abilities are proving efficacious in this population. This article will address common sequelae of cardiotoxic treatment regimens and offer recommendations for echocardiographic surveillance...
