Background: Chronic hypercapnic respiratory failure (HRF) in obesity hypoventilation syndrome (OHS) is commonly treated using non-invasive ventilation (NIV). We hypothesised that treatment of OHS would improve neural respiratory drive index (NRDI) and cardiac function. Methods: Fourteen patients (8 females) with OHS, who were admitted for initiation of domiciliary NIV, were prospectively studied. Patients had (mean ± SD): age (53±10 years), body mass index (BMI) (50...

AIM: Reversible myocardial dysfunction is common after out-of-hospital cardiac arrest (OHCA). The aim of this study was to determine if changes on serial transthoracic echocardiography (TTE) can predict long-term mortality in OHCA subjects. METHODS: This is a single-center historical cohort study of OHCA subjects undergoing targeted temperature management who received >1 TTE during hospitalization. Two-dimensional and Doppler parameters of systolic and diastolic function were compared between paired TTE...

Angiosarcomas of the uterine is a malignant and poor prognostic tumor and can either be a primary sarcoma or arising secondary to radiotherapy of a more complex tumor. Primary uterine angiosarcomas are exceptional and probably arise from embryonic vascular remnants, teratoma or from the rich uterine vasculature. We reported a rare case of primary angiosarcoma of uterine that at the time of diagnosis presented with sign and symptom of local and distant metastasis. The patient presented with dyspnea, chest pain, and history of vaginal bleeding and pelvic pain...

The transcatheter aortic valve implantation (TAVI) consist an alternative treatment in patients with severe aortic stenosis. Multimodality imaging using transthoracic echocardiography (TTE) or transesophageal echocardiography (TOE) and multislice CT (MSCT) constitute cornerstone techniques for the pre-operative management, peri-procedural guidance, follow up and recognition of possible transcatheter valve related complications. CT angiography is much more accurate regarding the total definition of aortic annulus diameter and circumferential area...

BACKGROUND: The objective was to better understand Doppler hemodynamics and exercise capacity in patients with Fontan palliation by delineating the hemodynamic mechanism for temporal changes in their peak oxygen consumption (V̇o2). METHODS: We performed a retrospective review of adult Fontan patients with systemic left ventricle (LV) who underwent serial transthoracic echocardiograms (TTE) and cardiopulmonary exercise tests (CPET) at Mayo Clinic in 2000-2015. TTE and CPET data were used (1) to determine agreement between V̇o2 and Doppler-derived LV function indices (eg, stroke volume index [SVI] and cardiac index [CI]) and (2) to determine agreement between temporal changes in peak V̇o2 and LV function indices...

BACKGROUND: Non-ST elevation myocardial infarction (NSTEMI) is a common manifestation of acute coronary syndrome (ACS), but delayed diagnosis can increase mortality. In this proof of principle study, the emergency physician performed transthoracic echocardiography (TTE) on scene to determine whether NSTEMI could be correctly diagnosed pre-hospitalization. This could expedite admission to the appropriate facility and reduce the delay until initiation of correct therapy. METHODS: Pre-hospital TTE was performed on scene by the emergency physician in patients presenting with ACS but without ST-elevation in the initial 12-lead electrocardiography (ECG) (NSTE-ACS)...

BACKGROUND: Artificial chord implantation has become one of the most applied techniques for mitral valve repair (MVR). Many techniques have been described with the goal of optimizing neochord implantation. A new annuloplasty device designed to simplify the determination of appropriate neochord length has been recently introduced. We will describe our initial experience with this new device. METHODS: The semirigid device is equipped with removable loops on the posterior aspect of the ring...

RATIONALE: Purulent pericarditis is a rare and usually fatal disease. Immunodeficiency state and preexisting pericardial effusion can predispose patients to infections. However, we are not aware of similar cases in patients with adult-onset Still's disease (AOSD). In addition, it is seldom caused by Salmonella bacteria. PATIENT CONCERNS: We report a 30-year-old woman with dyspnea on exertion and epigastric fullness. She was newly diagnosed with AOSD 4 months previously and medicated with prednisolone...

Transcatheter aortic valve replacement (TAVR) has been a revolutionary technique in the treatment of degenerative aortic valve stenosis. Selection of appropriate patients and appropriate valve size is crucial for improved patient outcome. Echocardiographic imaging is a critical component for patient selection and plays an important role in the selection of valve size, procedural guidance, and patient follow-up. This review discusses role of echocardiography in patient selection, device implantation, and postimplant follow-up for the first-generation CoreValve as used in pivotal trial...

Tricuspid annular plane systolic excursion (TAPSE) is a robust measure of RV function, but the performance of transesophageal echocardiography (TEE) measured TAPSE during surgery is not well established. We aim to evaluate feasibility of various TEE views before, during and after surgery. Furthermore, we compare performance of individual TEE measurements depending on view and method (AMM- and M-mode as well as 2D) as well as TAPSE measured using TEE with transthoracic echocardiography (TTE) TAPSE. The study was conducted from January 2015 through September 2016...

PURPOSE: Hip and knee arthroplasty surgeries are associated with embolism of materials such as air, cement, and fat. Patent foramen ovale (PFO) is a common congenital cardiac condition that has been reported to lead to paradoxical embolism. This observational study aimed to investigate if the presence of a PFO was associated with an increased risk of postoperative delirium in patients undergoing primary elective hip or knee arthroplasties. METHOD: This was a prospective cohort study at a tertiary teaching hospital...

INTRODUCTION: Dislocation of the elbow associated with radial head and coronoid fracture, the so-called "terrible triad" of the elbow, is challenging to treat and has a history of complicated outcomes. This study is to compare the clinical outcome of a single lateral approach-the extensile splitting extensor digitorum communis (EDC) approach and combined lateral and medial (CML) approaches for the treatment of terrible traid of the elbow (TTE). MATERIAL AND METHODS: After appropriate exclusion, 60 TTE patients (28 patients in the EDC group, 32 patients in the CML group) from 2009 January to 2015 August were reviewed in this study...

There is evidence suggesting diaphragmatic fatigue (DF) occurs relatively early during high-intensity exercise; however, studies investigating the temporal characteristics of exercise-induced DF are limited by incongruent methodology. Eight healthy adult males (25 {plus minus} 5 years) performed a maximal incremental exercise test on a cycle ergometer on Day 1. A constant load time-to-exhaustion (TTE) exercise test was conducted on Day 2 at 60% delta between the calculated gas exchange threshold and peak work rate...

A 51-year-old man presented with chest pain, high troponin level, inflammatory syndrome and ST-segment elevation in the anterior leads. While the transthoracic echocardiogram (TTE) showed anteroseptal hypokinesis and apical akinesis, the coronary angiogram was normal. Cardiac MR demonstrated a typical aspect of myocarditis (multiple areas of mid-myocardial late gadolinium enhancement, sparing the subendocardial layer, along with oedema). The initial diagnosis was clinically suspected myocarditis with pseudoinfarct presentation...
