BACKGROUND: Asymptomatic left ventricular (LV) dysfunction is highly prevalent in type 2 diabetes patients. Unlike the other hypoglycemic drugs, SGLT2 inhibitors have shown potential benefits for reducing cardiovascular death and risk factors, aside from lowering plasma glucose levels. With this study we aim at determining whether the treatment with empagliflozin is associated with an improvement in LV functions in diabetic patients with asymptomatic LV dysfunction against Sitagliptin, which is presumably neutral on myocardial function...

AIMS: Quantification of systolic function in patients with atrial fibrillation (AF) is challenging. A novel approach, based on RR interval correction, to counteract the varying heart cycle lengths in AF has recently been proposed. Whether this method is superior in patients with systolic heart failure (HFrEF) with AF remains unknown. This study investigates the prognostic value of RR interval-corrected peak global longitudinal strain {GLSc = GLS/[RR^(1/2)]} in relation to all-cause mortality in HFrEF patients displaying AF during echocardiographic examination...

AIMS: Although echocardiography is generally used for the diagnosis of heart failure with preserved ejection fraction (HFpEF), invasive measurements of filling pressures are the gold standard. Studies simultaneously performing echocardiography and invasive measurements in HFpEF are sparse. METHODS AND RESULTS: Invasive haemodynamic and echocardiographic measurements were simultaneously performed in 98 patients with heart failure New York Heart Association class ≥II, left ventricular ejection fraction (LVEF) ≥45%, and suspected pulmonary hypertension on a previous echocardiogram...

BACKGROUND: Inhibition of the renin-angiotensin axis can reduce the likelihood of atrial fibrillation (AF). However, the effects of angiotensin-converting-enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) on thrombogenicity in AF remain incompletely elucidated. Thisretrospective case-control study was conducted to evaluate whether the use of ACEI or ARB could reduce the incidence of left atrial appendage thrombus (LAAT) and spontaneous echocardiographic contrast (SEC) in patients with AF...

BACKGROUND: Ischemic mitral regurgitation (iMR) predisposes to right ventricular (RV) pressure and volume overload, providing a nidus for RV dysfunction (RVDYS) and non-ischemic fibrosis (NIF). Echocardiography (echo) is widely used to assess iMR, but performance of different indices as markers of RVDYS and NIF is unknown. METHODS: iMR patients prospectively underwent echo and cardiac magnetic resonance (CMR) within 72 hours. Echo quantified iMR, assessed conventional RV indices (TAPSE, RV-S', fractional area change [FAC]), and strain via speckle tracking in apical 4-chamber (global longitudinal strain [RV-GLS]) and parasternal long axis orientation (transverse strain)...

Right ventricular (RV) structure and function is clinically important in a wide range of conditions. While conventional echocardiography (echo) methods are widely used, its limitations in RV assessment due its complex geometry are well recognized. New applications of traditional echo methods as well as emerging echo techniques including 3-dimensional (3D) echo and speckle tracking strain have the potential to overcome limitations of conventional echo, though widespread clinical use remains to be seen. Volumetric methods using cardiac magnetic resonance (CMR) and computed tomography (CT) provide accurate assessment of RV function without geometric assumptions...

Transplant coronary artery vasculopathy (TCAV) following orthotopic heart transplantation (OHT) continues to be the primary reason for late graft failure in children. The current gold standard of diagnosis of TCAV is coronary angiography with or without intravascular ultrasound. This study investigates the longitudinal use of speckle-tracking echocardiographic strain imaging as an early non-invasive marker to screen for development of TCAV. Echocardiograms from patients who underwent OHT between 2006 and 2010 at Children's Hospital Colorado (n = 50) were retrospectively assessed...

A 14-year-old American Staffordshire terrier was presented for episodes of exercise-induced syncope. At admission, atrial flutter coupled to third-degree atrioventricular block was diagnosed electrocardiographically. On the second day of hospitalization, surface electrocardiogram revealed spontaneous conversion to sinus rhythm with persistence of atrioventricular block. Complete transthoracic echocardiograms were performed after each electrocardiographic examination. The combined use of conventional echocardiography with tissue Doppler imaging-based modalities allowed to investigate the atrial electromechanical correlation and function during typical atrial flutter and after its resolution...

A healthy 19-year-old man was referred to our hospital due to an elongated left heart border on chest radiograph. Transthoracic echocardiography showed a posteriorly deviated left ventricular apex, increased right ventricular dimension, and hypokinesis of the interventricular septum. Pulsed Doppler echocardiogram revealed a triphasic mitral inflow pattern. Myocardial longitudinal strain rate imaging revealed that the early diastolic strain rate abruptly decreased to a negative value and then became positive at the left ventricular apex...

The poor prognosis of cardiac sarcoidosis (CS) underscores the need for risk stratification. We evaluated 84 consecutive sarcoidosis patients who were referred for echocardiographic studies for cardiac symptoms or abnormal electrocardiograms. In 54 patients without previous diagnosis of CS or other known structural heart disease, 13 reached endpoints during (median) 24 months follow up. Significantly impaired peak systolic longitudinal strain in their original echocardiograms were identified in 13 of 17 left ventricular segments, clustering in the free wall, interventricular septum and apex...

Prevention strategies are important to optimize and to manage heart care in breast cancer survivors. Regular physical activity at moderate intensity is normally proposed to maintain myocardial performance; however, no data is available about the different impact of different levels of physical exercise. 2D speckle tracking echocardiography (2DSTE) is an accepted method for early detection of myocardial dysfunction. The study aims to monitor the cardiac performances in breast cancer survivors by 2DSTE analysis to manage sports activity vs physical activity...

Cardiac involvement is common in patients with light-chain (AL) amyloidosis and portends a poor prognosis, although little is known about the changes in cardiac mechanics after chemotherapy. We sought to explore the relation between amyloidosis staging and baseline cardiac mechanics and to investigate short-term changes in cardiac mechanics after chemotherapy. We identified 41 consecutive patients from the Stanford Amyloid Center who had echocardiograms and free light-chain values before and after chemotherapy, along with 40 age- and gender-matched controls...

BACKGROUND: Women who have coronary artery disease (CAD) often present with atypical symptoms that may lead to misdiagnosis. We assessed strain, systolic strain rate and left ventricular dyssynchrony with 2- dimensional- speckle tracking echocardiography to evaluate its use as a non-invasive method for detecting CAD in women with normal ejection fraction compared with healthy women controls with a normal angiogram. METHODS: We included 35 women with CAD confirmed by coronary angiography and a positive exercise stress echocardiography and 35 women in a control group with a low pretest probability of CAD, normal angiogram and a normal stress echocardiography with normal EF...

In this case report, we describe an unusual episode of bilateral submassive pulmonary embolism (PE) caused by a popliteal vein aneurysm (PVA). The development of PE stems from many risk factors including obesity (BMI³ 30 kg/m2), hypertension, cigarette smoking (greater than 25 cigarettes per day), increasing age, surgery, immobility, malignancy, and inherited thrombophilia. A PVA is a rare but significant cause of PE. A 28-year-old male presented to the emergency department with progressive shortness of breath...
