bedside ultrasound heart failure

The utilization of ultrasound has rapidly increased over the past few decades due to its ease of use, wider availability of portable machines, broad applicability, non-invasiveness, and real-time imaging. A varied spectrum of clinical conditions such as diverse lung pathologies and various etiologies of acute circulatory failure can be rapidly ascertained using bedside ultrasonography. It has been shown that lung ultrasonography has more sensitivity than chest x-ray in detecting pulmonary congestion in heart failure, subpleural lung consolidation in pneumonia, and characterizing and detecting even minimal pleural effusions...

PURPOSE: Heart failure (HF) often coexists with chronic obstructive pulmonary disease (COPD) and is associated with worse outcomes. We aimed to assess the feasibility of detecting vertical artifacts (B-lines) on lung ultrasound (LUS) to identify concurrent HF in patients hospitalized with acute exacerbation of COPD (AECOPD). Second, we wanted to assess the association between B-lines and the risk of rehospitalization for AECOPD or death. PATIENTS AND METHODS: In a prospective cohort study, 123 patients with AECOPD underwent 8-zone bedside LUS within 24h after admission...

Congestive nephropathy is kidney dysfunction caused by the impact of elevated venous pressures on renal hemodynamics. As a part of cardiorenal syndrome, the diagnosis is usually made based on history and physical examination, with findings such as jugular venous distension, a third heart sound, and vital signs as supporting findings. More recently, however, these once though objective measures have come under scrutiny for their accuracy. At the same time, bedside ultrasound has increased in popularity and is routinely being used by clinicians to take some of the guess work out of making the diagnosis of volume overload and venous congestion...

Pulmonary arterial hypertension (PAH) is a rare condition with the potential to progress to right heart failure. Point-of-Care Ultrasonography (POCUS), used and interpreted in real time at the bedside to further the cardiopulmonary assessment, has the potential to improve the longitudinal care of PAH patients in the ambulatory setting. Patients from PAH clinics at two academic medical centers were randomized to either a POCUS assessment cohort or non-POCUS standard care (ClinicalTrials.gov identifier NCT05332847)...

Point-of-care ultrasonography (POCUS) represents a goal-directed ultrasound examination performed by clinicians directly involved in patient healthcare. POCUS has been widely used in emergency departments, where US exams allow physicians to make quick diagnoses and to recognize early life-threatening conditions which require prompt interventions. Although initially meant for the real-time evaluation of cardiovascular and respiratory pathologies, its use has been extended to a wide range of clinical applications, such as screening for deep-vein thrombosis and trauma, abdominal ultrasonography of the right upper quadrant and appendix, and guidance for invasive procedures...

Lung ultrasound (LUS) has become one of the most exciting applications in neonatal point-of-care ultrasound (POCUS), yet still lacks routine clinical use. This study assesses the utility of LUS for neonatal respiratory disorders (NRDs) diagnosis and follow-up compared to chest X-ray (CXR). A prospective cross-sectional study was conducted on 100 neonates having NRDs with a gestational age ≥28 weeks, excluding those having multiple congenital anomalies, chromosomal aberrations, hydrops fetalis and/or heart failure...

Point-of-care ultrasound (POCUS) plays a strategic role in the diagnostic and therapeutic evaluation of critically ill patients and, especially, in those who are haemodynamically unstable. In this context, POCUS allows a more precise identification of the cause, its differential diagnosis, the eventual coexistence with another entity and, finally, guiding of the therapeutic approach. It implies a portable use of ultrasound in acute settings covering different specified protocols, such as echocardiography, vascular, lung or abdominal ultrasound...

BACKGROUND: Current noninvasive estimation of right atrial pressure (RAP) by either bedside jugular venous pressure exam or inferior vena cava measurement during a comprehensive echocardiogram offers imprecise estimates of actual RAP. METHODS: We enrolled 41 patients in a prospective, blinded study to validate a novel point-of-care ultrasound method using direct right atrial depth (RAD) measurement and jugular venous ultrasound to estimate RAP. Two subjects were excluded, and 39 were included in the final analysis...

A 59-year-old female with a history of stage IV lung adenocarcinoma presented with worsening shortness of breath and cough over several weeks. She was tachycardic, hypotensive, and tachypneic. Portable chest x-ray suggested bilateral pleural effusions and computed tomography angiography (CTA) revealed bilateral pulmonary emboli (PE) with suspected right heart strain. Upon admission to the medical intensive care unit for treatment of PE, bedside echocardiography was performed to direct management. Indicators of cor pulmonale and right heart strain were apparent including right ventricle dilation, reduced tricuspid systolic excursion, and a deformed left ventricle with "D sign"...

BACKGROUND: Point-of-care ultrasound is a fundamental tool in the emergency department when managing the critically ill patient. Determining a patient's hemodynamic status at the bedside can better guide resuscitation efforts. The left ventricular outflow tract velocity-time integral (VTI) is a validated, noninvasive, and rapidly acquired echocardiographic measurement that is analogous to stroke volume. DISCUSSION: VTI can be used to determine fluid responsiveness and to risk stratify patients, particularly in pulmonary embolism, heart failure, and sepsis...

Organ congestion from venous hypertension is an important pathophysiological mechanism mediating organ injury in several clinical contexts including critical illness, congestive heart failure and end-stage chronic kidney disease. However, the practical evaluation of venous congestion is often challenging at the bedside because of the limitations of traditional methods. Point-of-care ultrasound (POCUS) enables the clinician to assess venous velocity profiles during the cardiac cycle using Doppler modalities...

Fat embolism syndrome (FES), causing right heart dysfunction, is a rare disease that is often difficult to diagnose with imaging modalities such as computed tomography (CT). FES is the clinical presentation that follows the entry of fat globules into the systemic circulation, which typically results in respiratory failure, scattered petechiae, cardiovascular collapse, and neurological sequelae. It is mostly observed in the cases of orthopedic trauma but may occur in any circumstance where fat can enter the circulatory system...

Heart failure (HF) is a global public health burden, characterized by frequent emergency department (ED) visits and hospitalizations. Identifying successful strategies to avoid admissions is crucial for the management of acutely decompensated HF, let alone resource utilization. The primary challenge for ED management of patients with acute heart failure (AHF) lies in the identification of those who can be safely discharged home instead of being admitted. This is an elaborate decision, based on limited objective evidence...

Fluid overload has been associated with morbidity and mortality in various clinical scenarios including heart failure and critical illness. It exerts pathologic sequelae in almost all the organ systems. Proper management of patients with fluid overload requires knowledge of the underlying pathophysiology, objective evaluation of volume status, selection of appropriate therapeutic options, and maintenance and modulation of tissue perfusion. There are several methods to appraise volume status but none without limitations...

OBJECTIVE: arterial hypertension is a major pandemic in the modern world and is a common cause of heart failure. Identification of pulmonary and venous congestion is relevant in patients with arterial hypertension(AH) and decompensated heart failure (DHF). DESIGN AND METHOD: to assess the severity and dynamics of venous congestion (VC) by VExUS (including the study of the inferior vena cava (IVC), porto-hepatic and renal blood flow), and pulmonary congestion (PC) by LUS (with B-lines assessment according to 8-zone method) in patients with AH and DHF at admission to hospital and at discharge...

For the acutely dyspneic patient, discerning bedside between acute decompensated heart failure (ADHF) and COVID-19 is crucial. A lung ultrasound (LUS) is sensitive for detecting these conditions, but not in distinguishing between them; both have bilateral B-lines. The Blue protocol uses pleural sliding to differentiate decreased pneumonia; however, this is not the case in ADHF. Nonetheless, this pleural sliding has never been quantified. Speckled tracking is a technology utilized in the echocardiography field that quantifies the motion of tissues by examining the movement of ultrasound speckles...

Background: Mediastinal mass is an entity with variable pathology and clinical spectrum. Anterior mediastinal mass can result in severe symptoms due to involvement of surrounding vital structures such as the great vessels, trachea-bronchial tree, and heart. We highlight a case of cardiac tamponade in a patient with an anterior mediastinal mass that was paradoxically worsened after decompressive pericardiocentesis. Case summary: A 21-year-old male presented to the emergency department (ED) with breathlessness and hypotension...

We explored the application value of bedside ultrasound dynamic monitoring of the inferior vena cava diameter (IVCD) and collapse with sniff (inferior vena cava collapsibility index [IVCCI]) to guide dehydration adjustment in continuous renal replacement therapy (CRRT) in patients with combined renal failure and acute heart failure. We selected 90 patients with combined renal and acute heart failure who required CRRT in the intensive care unit (ICU) from January 2019 to June 2021. According to different blood volume assessment methods, patients were randomly divided into ultrasound, experience, and control groups...

BACKGROUND: In emergency medicine, ultrasound is frequently used in the diagnostic and therapeutic procedures and evaluation of treatment of critically ill patients simultaneously, due to its bedside applicability, rapidness and inexpensive cost. AIM: The competence of emergency physician in focused cardiac ultrasound evaluations and the success of diagnosing cardiac diseases were evaluated in a patient group presenting to the emergency department with complaints of non-traumatic chest pain and shortness of breath...
