Aortic valve intervention (AVI) in patients with a severe aortic stenosis (AS) and a preserved left ventricular ejection fraction (LVEF) is controversial. Mitral annular plane systolic excursion (MAPSE) is an easily acquired metric of left ventricular longitudinal shortening. We sought to investigate if an asymptomatic decrease in MAPSE preceded the need for AVI in asymptomatic patients with AS and a preserved LVEF. In this retrospective cohort study, we identified 205 consecutive patients (56% male, 73 ± 11 years) with at least a moderate AS and a normal LVEF who underwent a serial outpatient transthoracic echocardiography (TTE) from 2006 to 2013...

A 57-year-old man presented with abdominal pain, hematemesis, and melena. He reported taking high-dose ibuprofen for back pain and drinking several 24-ounce beers daily. Examination was remarkable for icteric sclera, poor dentition, tachycardia, and crescendo-decrescendo murmur at right upper sternal border, radiating to the carotids. Labs revealed leukocytosis, anemia, thrombocytopenia, and elevated liver function tests and INR. Endoscopy demonstrated antral ulcers, duodenitis, and esophagitis. Blood cultures were obtained and broad-spectrum antibiotics started; cultures later grew Streptococcus mitis, and antibiotic coverage was narrowed...

BACKGROUND: No established measure of concentric left ventricular wall hypertrophy (cLVH) on routine computed tomography (CT) of the adult chest currently exists. The objective of this study was to identify and test linear measures for the detection of cLVH using transthoracic echocardiography (TTE) as the reference standard. METHODS: Contrast-enhanced non-electrocardiogram-gated chest CTs acquired within two weeks of TTE were retrospectively evaluated. Two radiologists independently made trans-axial measurements in the proximal half of the left ventricle at its approximate widest internal diameter: maximum septal thickness (sept), maximum lateral wall thickness (lat), and inner (Id) and outer (Od) wall-wall diameters at the level of greatest combined myocardial thickness...

We report on an 84-year-old woman with anteroseptal acute myocardial infarction. Emergency coronary angiography revealed the occlusion of proximal left anterior descending artery without collateral circulation, and percutaneous coronary intervention was performed. Two drug eluting stents were implanted, and the procedure was concluded with thrombolysis in myocardial infarction grade 3 without complications. Postoperatively, no murmur was audible on auscultation and no shunt flow was observed on transthoracic echocardiography (TTE), and normal blood pressure was maintained...

The purpose of this study was to investigate the effects of adding strength training with or without vibration to cross-country (XC) skiers' endurance training on double poling (DP) performance, physiological and kinematic adaptations. Twenty-one well-trained male XC skiers combined endurance- and upper-body strength-training three times per week, either with (n=11) or without (n=10) superimposed vibrations for 8 weeks, whereas eight skiers performed endurance training only (CON). Testing included 1RM in upper-body exercises, work economy, neural activation, oxygen saturation in muscle and DP kinematics during a prolonged submaximal DP roller ski test which was directly followed by a time to exhaustion (TTE) test...

This article presents the case of a 53-year-old man who presented with acute right superficial femoral and popliteal arterial thrombosis for which he underwent an emergent uncomplicated thrombectomy. He denied preceding cardiovascular or neurologic symptomatology and had no history of coronary or peripheral arterial disease, trauma, hypercoagulability, or malignancy. However, he reported having several days of intense emotional stress prior to presentation. His cardiac exam was normal, his electrocardiogram showed normal sinus rhythm and nonspecific ST-T wave abnormalities, and his troponin levels were normal...

BACKGROUND: Meaningful translational large animal models for cardiac diseases are indispensable for studying disease mechanisms, development of novel therapeutic strategies, and evaluation of potential drugs. METHODS: For induction of heart failure, cardiac hypertrophy and fibrosis, a bare metal stent was implanted in the descending aorta of growing pigs (n = 7), inducing pressure stress on the left ventricle (group HYPI). The constant stent size in growing pigs resulted in antegrade partial obstruction of the aortic flow with a gradual increase in afterload...

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: Acute exercise performance can be limited by arterial hypoxemia, such that hyperoxia may be an ergogenic aid by increasing tissue oxygen availability. Hyperoxia during a single bout of exercise performance has been examined using many test modalities, including time trials (TTs), time to exhaustion (TTE), graded exercise tests (GXTs), and dynamic muscle function tests. Hyperoxia has also been used as a long-term training stimulus or a recovery intervention between bouts of exercise...

BACKGROUND: Pulmonary hypertension (PH) is an important lethal manifestation of systemic sclerosis (SSc). Evidence of an association between peripheral and pulmonary arterial vasculopathy in SSc has been demonstrated. We hypothesized that peripheral arterial stiffness could predict PH in SSc. METHODS: We performed a cross-sectional study among patients with SSc who underwent Cardio-Ankle Vascular Index (CAVI, VaSera VS-1000; Fukuda Denshi, Tokyo, Japan) and transthoracic echocardiography (TTE) examination to evaluate peripheral arterial stiffness and PH, respectively...

BACKGROUND: Dexmedetomidine (DEX) has been used for sedation in young infants and children undergoing transthoracic echocardiography (TTE). The median effective dose of intranasal DEX has not been described for postcardiac surgery children. Postcardiac surgery children could require more DEX to achieve satisfactory sedation for TTE examination than children suspected of congenital heart disease. OBJECTIVES: To study whether postcardiac surgery children need a larger dose of DEX for TTE than normal children...

BACKGROUND: Right ventricular systolic pressure (RVSP) estimated by echocardiography is critical for the initial screening and follow-up of pulmonary hypertension (PH). Inter-observer variability (IOV) in RVSP can impact clinical decision making. This study assessed whether a simple guideline-based teaching intervention could reduce the IOV in RVSP interpretation. METHODS AND RESULTS: Eleven participants in a high-volume tertiary level echocardiography laboratory underwent an assessment of the baseline IOV in the assessment of RVSP for a series of transthoracic echocardiograms (TTE), depicting various degrees of PH among 8 cases each before and after a teaching intervention...

Left atrium (LA) size is a well-studied predictor of atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). Yet, there is still little agreement on the best imaging technique to size the LA, and on the most appropriate sizing parameter. Volumetric assessment of LA with three-dimensional rotational angiography (3DRA LA volume index) might be a valid alternative to the commonly used transthoracic echocardiography (TTE LA volume index). The aim of our study was to investigate whether LA volume by 3DRA at the time of PVI is able to predict the risk of atrial fibrillation recurrence...
