The point-of-care ultrasound exam has become an essential tool for hemodynamic monitoring and resuscitation in the trauma bay as well as the intensive care unit. Transthoracic ultrasound provides a dynamic assessment of cardiac function, volume status, and fluid responsiveness that offers potential advantage over traditional methods of hemodynamic monitoring. More recently, a focused transthoracic echocardiography exam was described to improve immediate resuscitation of severely injured patients in the trauma bay...

BACKGROUND: Catheter and surgical ablation of atrial fibrillation (AF) can be associated with a risk of thromboembolic events. The goal of this study was to assess optimal anticoagulation management during thoracoscopic ablation of AF. METHODS: Fifty-two patients with persistent or long-standing persistent AF underwent hybrid ablation consisting of thoracoscopic ablation followed by electrophysiologic (EP) evaluation and consecutive ablation if indicated. The thoracoscopic ablation was performed using three different anticoagulation protocols: (1) without periprocedural heparin and without occlusion of the left atrial appendage; (2) with periprocedural heparin but without left atrial appendage occlusion; and (3) with periprocedural heparin and left atrial appendage occlusion...

BACKGROUND: It is unknown whether contrast transcranial color-coded sonography of vertebral artery monitoring via the foramen magnum window (cTCCS-VA) is useful to detect right-to-left shunt (RLS). We investigated whether cTCCS-VA can be proposed as an alternative to middle cerebral artery monitoring via the temporal bone window (cTCCS-MCA) for RLS detection, as compared with contrast transesophageal echocardiography (cTEE). METHODS: We evaluated 112 patients with ischemic stroke or transient ischemic attack...

BACKGROUND: Transesophageal echocardiography (TEE) is a valuable monitor for patients undergoing cardiac and noncardiac surgery as it allows for evaluation of cardiovascular compromise in the perioperative period. It is challenging for anesthesiology residents and medical students to learn to use and interpret TEE in the clinical environment. A critical component of learning to use and interpret TEE is a strong grasp of normal cardiovascular ultrasound anatomy. METHODS: Fifteen fourth-year medical students and 15 post-graduate year (PGY) 1 and 2 anesthesiology residents without prior training in cardiac anesthesia or TEE viewed normal cardiovascular anatomy TEE video clips; participants were randomized to learning cardiac anatomy in generative retrieval (GR) and standard practice (SP) groups...

A 79-year-old man with history of aortic stenosis, status post bioprosthetic aortic valve replacement, episodes of bacteremia, and endocarditis presented to hospital with fever. Clinical assessment led to suspicion of possible endocarditis. Initial interpretation of transesophageal echocardiogram was inconclusive without vegetation in mitral/aortic valve. An In-leukocyte scan demonstrated increased uptake in the area of aortic valve, suggestive of infection. Further review of the transesophageal echocardiogram showed signs of annular abscess...

Background.: The presence of patent foramen ovale (PFO) has been linked to many illness, including cryptogenic stroke, transient ischemic attack, migraine, platypnea-orthodeoxia syndrome and decompression sickness in scuba divers. Transesophageal echocardiography is the gold standard technique for the visualization of atrial septal anatomy, but it is a secondary level exam, not always available, with additional associated costs and not completely free from procedural risks. Standard transthoracic echocardiography (TTE) has a too low sensitivity for PFO screening...

INTRODUCTION: Cor triatriatum is a congenital cardiac anomaly in which the left (sinister) or right (dexter) atrium is divided into two compartments by residual embryonic tissue, resulting in a tri-atrial heart. As cor triatriatum dextrum can present clinically in various ways and have multiple associated cardiac anomalies, this report attempts to contribute to what is known about this exceedingly rare disorder. CASE: A 40 year old Hispanic man with a medical history of gastritis presented with complaints of palpitations, dizziness and bilateral lower extremity edema...

INTRODUCTION: Dehiscence of a mitral valve annuloplasty ring is a rare occurrence that often manifests as mitral regurgitation and heart failure. We present a case of mitral ring dehiscence which was initially unrecognized by standard 2-dimensional transthoracic echocardiography (2D TTE); and 2-dimensional transesophageal echocardiography (2D TEE);. CASE: A 65-year-old woman was referred to Cardiology clinic for evaluation of dyspnea. Her history included tobacco abuse, atrial fibrillation status post pulmonary vein isolation, nonischemic cardiomyopathy, and prior mitral valve repair with annuloplasty ring for rheumatic valvular disease...

BACKGROUND: Transesophageal echocardiography (TEE) is routinely performed before atrial fibrillation (AF) transcatheter ablation to exclude the presence of left atrial (LA) or LA appendage (LAA) thrombi. The aim of the study is to evaluate if easily accessible clinical parameters may relate to the presence of LA or LAA thrombi to identify patients who could potentially avoid TEE. METHODS AND RESULTS: Between January 2012 and September 2014, data from 1539 consecutive patients undergoing TEE, as a work-up before AF transcatheter ablation, in six large volume centers were collected...

Laparoscopic hepatectomy carries a high risk of gas embolism due to the extensive hepatic transection plane and large hepatic vena cava. Here, we compared the influence of inhaled and intravenous anesthetics on gas embolism during laparoscopic hepatectomy. Fifty patients undergoing laparoscopic hepatectomy were divided into two groups to receive sevoflurane anesthesia (group S, n = 25) or intravenous propofol anesthesia (group p, n = 25). During the operation, gas emboli were detected by transesophageal echocardiography and graded according to their size...

BACKGROUND AND PURPOSE: Etiology of acute ischemic stroke remains undetermined (cryptogenic) in about 25% of patients after state-of-the-art diagnostic work-up. METHODS: One-hundred and three patients with magnetic resonance imaging (MRI)-proven acute ischemic stroke of undetermined origin were prospectively enrolled and underwent 3-T cardiac MRI and magnetic resonance angiography of the aortic arch in addition to state-of-the-art diagnostic work-up, including transesophageal echocardiography (TEE)...

OBJECTIVE: The aim of our study was to evaluate the level of agreement between tricuspid annular plane systolic excursion (TAPSE) measured by transthoracic echocardiography (TTE) and TAPSE measured using transesophageal echocardiography (TEE) in anesthetized patients. MATERIALS AND METHODS: Thirty patients scheduled for elective cardiac surgery were prospectively studied. Shortly after induction of anesthesia before the operation, TAPSE was measured by TTE using M-mode in apical 4chamber view (4CH) and by TEE in six different views: using 2D echocardiography in midesophageal (ME) 4CH view, using M-mode in deep transgastric right ventricle (dTG RV) view at 0° and dTG RV longaxis view (LAX) as well as using anatomical M-mode (AM-mode) in ME 4CH, dTG RV at 0° and dTG RV LAX views...

BACKGROUND: Microsurgical resection of vestibular schwannomas is demanding, even if not all of these tumors represent a challenge for experienced surgeons. In order to make the right decisions when it comes to balancing the extent of tumor resection with preservation of function, the surgeon must possess detailed knowledge of the surgical techniques and also have mastered these. OBJECTIVE: The current article describes the state-of-the-art of the three major microsurgical techniques for resection of vestibular schwannomas, their pearls and their perils...

Two children with congenital heart disease status post surgical correction presented with prolonged constitutional symptoms, hepatosplenomegaly and pancytopenia. Concern for malignancy prompted bone marrow biopsies that were without evidence thereof. In case 1, echocardiography identified a multilobulated vegetation on the conduit valve. In case 2, transthoracic, transesophageal and intracardiac echocardiography were performed and were without evidence of cardiac vegetations; however, pulmonic emboli raised concern for infective endocarditis...

Oral anticoagulant therapy (OAT) is a mainstay of atrial fibrillation (AF) pharmacological treatment. Left atrial appendage closure is a possible treatment, when feasible, in patients with intracerebral hemorrhage during OAT. We report a case of right atrial appendage thrombosis in a patient with chronic AF admitted for syncope due to diuretic-induced orthostatic hypotension. Two years previously, he had undergone left atrial appendage closure with the Amplatzer Cardiac Plug device because of intracerebral hemorrhage during OAT...

Tricuspid regurgitation (TR) is commonly encountered in the management of patients with a variety of cardiovascular diseases. Primary TR is the result of structural abnormalities of the valve or chordal attachments whereas functional TR results from alterations in right ventricular (RV) or right atrial (RA) size, shape or function. The vast majority of TR cases seen in practice are functional in nature and usually results from left-sided heart disease (e.g., mitral valve disease, left ventricular (LV) systolic dysfunction) and/or pulmonary vascular disease, though it also manifests in the presence of isolated chronic atrial fibrillation (AF)...

We report a 23-year-old woman, with three recent exertional syncopes. Transthoracic (TTE) and transesophageal (TEE) echocardiography found a large heterogeneous mass (38 x 35 mm) arising from the posterior mitral annulus, protruding in systole through the left ventricular outflow tract (LVOT). Heart MRI confirmed the echocardiography findings, suggesting a cardiac myxoma. Cardiac surgery accomplished the complete resection of the lesion, confirming a mass arising from the posterior mitral annulus and preserving mitral anatomy and function...
