Transthoracic echocardiography ( TTE transthoracic echocardiography ) is a critical tool in the field of clinical cardiology. It often serves as one of the first-line imaging modalities in the evaluation of cardiac disease owing to its low cost, portability, widespread availability, lack of ionizing radiation, and ability to evaluate both anatomy and function of the heart. Consequently, a large majority of patients undergoing a cardiac computed tomography (CT) or magnetic resonance (MR) imaging examination will have a TTE transthoracic echocardiography available for review...

BACKGROUND: Infective endocarditis rarely causes mitral valve stenosis. When present, it has the potential to cause severe hemodynamic decompensation and death. There are only 15 reported cases in the literature of mitral prosthetic valve bacterial endocarditis causing stenosis by obstruction. This case is even more unusual due to the mechanism by which functional mitral stenosis occurred. CASE PRESENTATION: We report a case of a 23-year-old white woman with a history of intravenous drug abuse who presented with acute heart failure...

Acute pulmonary embolism (PE) is a major cause of morbidity and mortality and is classified as massive (high risk), submassive (intermediate risk), or nonmassive (low risk) based on the hemodynamic status and clinical characteristics of the patient. At this time, the management of patients with submassive PE remains controversial and approaches for improving risk assessment are critical. In this review, we discuss several echocardiographic methods to assess right heart function that may aid in the risk assessment of patients with acute PE...

We report the case of a 79-year-old woman who presented to our hospital for elective removal of an infratentorial meningioma and suffered a periprocedural cardiac arrest. Shortly after uncomplicated induction of anesthesia prior to the surgery, the patient became hypotensive and bradycardic, culminating ultimately in a cardiac arrest with pulseless electrical activity. Return of spontaneous circulation occurred within 90 seconds of arrest, but the patient remained dependent on maximal doses of epinephrine and dopamine for hemodynamic support...

Up to 40% of patients with aortic stenosis (AS) harbor discordant Doppler-echocardiographic findings, the most common of which is the presence of a small aortic valve area (≤1.0 cm(2)) suggesting severe AS, but a low gradient (<40 mm Hg) suggesting nonsevere AS. The purpose of this paper is to present the role of multimodality imaging in the diagnostic and therapeutic management of this challenging entity referred to as low-gradient AS. Doppler-echocardiography is critical to determine the subtype of low-gradient AS: that is, classical low-flow, paradoxical low-flow, or normal-flow...

OBJECTIVES: Doxorubicin (DXR), an anthracyclic antineoplastic agent, is one of the most commonly drug utilized to induce dilated cardiomyopathy (DCM) and heart failure (HF), but the well optimized protocol for cardiomyopathy induction leading to development of cardiac systolic dysfunction is unclear. This study aims to critically compare short-term and long-term DXR injection protocols for the induction of DCM in rats. METHODS: Animals were allocated into 3 experimental groups: a ST (short-term DXR injection) group, in which animals received 6 intraperitoneal (i...

A system for collection, distribution, and long distant, asynchronous interpretation of cardiac auscultation has been developed and field-tested in rural China. We initiated a proof-of-concept test as a critical component of design of a system to allow rural physicians with little experience in evaluation of congenital heart disease (CHD) to obtain assistance in diagnosis and management of children with significant heart disease. The project tested the hypothesis that acceptable screening of heart murmurs could be accomplished using a digital stethoscope and internet cloud transmittal to deliver phonocardiograms to an experienced observer...

RATIONALE: Vascular maturation plays an important role in wound repair post-myocardial infarction (MI). The Notch3 is critical for pericyte recruitment and vascular maturation during embryonic development. OBJECTIVE: This study is to test whether Notch3 deficiency impairs vascular maturation and blunts cardiac functional recovery post-MI. APPROACH AND RESULTS: Wild type (WT) and Notch3 knockout (Notch3KO) mice were subjected to MI by the ligation of left anterior descending coronary artery (LAD)...

Primary mural endocarditis is an extremely rare infection in which nonvalvular endocardial involvement is seen without any cardiac structural abnormalities such as ventricular septal defects. The rapid and precise diagnosis of this disease remains challenging. We present 2 cases (67- and 47-year-old male patients) of pathologically confirmed primary mural endocarditis that could have been detected by initial transthoracic echocardiography in the emergency department. Transthoracic echocardiography and transesophageal echocardiography play critical roles in the early recognition and confirmation of primary mural endocarditis...

BACKGROUND: Diagnosing pericardial effusion is critical for optimal patient care. Typically, clinicians use physical examination findings and historical features suggesting pericardial effusion to determine which patients require echocardiography. The diagnostic characteristics of these tools are not well described. The objective of this study is to determine the prevalence of historical features and sensitivity of clinical signs to inform clinicians when to proceed with echocardiogram...

Reliable methods for measuring the thoracic aorta are critical for determining treatment strategies in aneurysmal disease. Z-scores are a pragmatic alternative to raw diameter sizes commonly used in adult medicine. They are particularly valuable in the pediatric population, who undergo rapid changes in physical development. The advantage of the Z-score is its inclusion of body surface area (BSA) in determining whether an aorta is within normal size limits. Therefore, Z-scores allow us to determine whether true pathology exists, which can be challenging in growing children...

Introduction Tele-echocardiography can ensure prompt diagnosis and prevent the unnecessary transport of infants without critical congenital heart disease, particularly at isolated locations lacking access to tertiary care medical centers. Methods We retrospectively reviewed all infants who underwent tele-echocardiography at a remote 16-bed level IIIB NICU from June 2005 to March 2014. Tele-echocardiograms were completed by cardiac sonographers in Okinawa, Japan, and transmitted asynchronously for review by pediatric cardiologists in Hawaii...

REVIEW
Peter McCanny, Frances Colreavy
Cardiac tamponade should be considered in a critically ill patient in whom the cause of haemodynamic shock is unclear. When considering tamponade, transthoracic echocardiography plays an essential role and is the initial investigation of choice. Diagnostic sensitivity of transthoracic echocardiography is dependent on image quality, and in some cases a transoesophageal approach may be required to confirm the diagnosis. Knowledge of the pathophysiology and echocardiographic features of cardiac tamponade are essential for the practicing Intensivist...

The current trend to treat hypotension in critically ill patients is to place a greater emphasis on inotropic support and less on fluid resuscitation in order to limit the potential harm from fluid overload. This combination may trigger left ventricular outflow tract obstruction (LVOTO) in susceptible patients. Although LVOTO is classically described in patients with hypertrophic cardiomyopathy it has been reported in other conditions including septic shock, apical ballooning syndrome, myocardial infarction, respiratory failure, and post valvular surgery...
