OBJECTIVES: This study sought to investigate the incidence, associated findings, and natural history of effusive-constrictive pericarditis (ECP) after pericardiocentesis. BACKGROUND: ECP is characterized by the coexistence of tense pericardial effusion and constriction of the heart by the visceral pericardium. Echocardiography is currently the main diagnostic tool in the assessment of pericardial disease, but limited data have been published on the incidence and prognosis of ECP diagnosed by echo-Doppler...

BACKGROUND: Pleural effusion (PLE) may lead to low blood pressure and reduced cardiac output. Low blood pressure and reduced cardiac output are often treated with fluid loading and vasopressors. This study aimed to determine the impact of fluid loading and norepinephrine infusion on physiologic determinants of cardiac function obtained by ultrasonography during PLE. METHODS: In this randomised, blinded, controlled laboratory study, 30 piglets (21.9 ± 1.3 kg) had bilateral PLE (75 mL/kg) induced...

BACKGROUND: Continuous-wave Doppler (CWD) ultrasound through the left ventricular outflow tract is one modality used for non-invasive cardiac output measurement. The ultrasonic cardiac output monitor (USCOM) is a relatively new monitor which uses a small, transcutaneous ultrasound probe to measure cardiac output with CWD via the suprasternal window. It is faster and less complex to train new users than conventional echocardiography. In addition to stroke volume (SV), the USCOM can calculate stroke volume variation (SVV) and the Smith-Madigan inotropy index (SMII), which is an estimate of the pre-load independent contractility of the myocardium...

OBJECTIVES: First, we aimed at assessing whether fluid responsiveness is predicted by the effects of an end-expiratory occlusion on the velocity-time integral of the left ventricular outflow tract. Second, we investigated whether adding the effects of an end-inspiratory occlusion and of an end-expiratory occlusion on velocity-time integral can predict fluid responsiveness with similar reliability than end-expiratory occlusion alone but with a higher threshold, which might be more compatible with the precision of echocardiography...

REVIEW
Heike Rabe, Hector Rojas-Anaya
During the transition to extrauterine life, preterm infants are at high risk of developing circulatory failure. Currently, hypotension is used as major diagnostic criteria for starting treatments such as fluid boluses, inotropes or steroids. Most of these treatment options have not been studied in large randomised controlled trials for efficacy and safety and are under discussions. A wide variety in their use is reported in the literature and clear evidence about which inotrope or other treatment should be preferred is lacking...

BACKGROUND: Fluid management remains a major challenge of hemodialysis (HD) care, with serious implications for morbidity and mortality. Intradialytic fluid management is typically guided by blood pressure, an indirect resultant of hemodynamics status. Direct measurements of hemodynamic parameters may improve cardiovascular outcomes by providing rational bases for intervention. We compare stroke volume (SV) measurements using a noninvasive, regional biompedance cardiography device (NiCaS) with Doppler echocardiography (Echo) in HD setting...

OBJECTIVE: To evaluate early and dynamic changes of the left ventricular systolic function of patients with septic shock by two-dimensional speckle tracking imaging (2D-STI), and to provide guidance for treatment and prognosis. METHODS: Fifty-eight septic shock patients admitted to intensive care unit (ICU) of Subei People's Hospital from January 2016 to April 2017 were enrolled. The septic shock patients were given early fluid resuscitation. The left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), early diastolic mitral flow velocity/early diastolic mitral annular peak velocity (E/Em) were obtained by conventional echocardiography, and the left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS) were obtained by 2D-STI before fluid resuscitation and 1, 3, 7, 14 days after fluid resuscitation...

The term pulmonary hypertension refers to a serious condition characterised by high pulmonary vascular pressure, mainly as a consequence of various cardiac and respiratory diseases. Current clinical classification of pulmonary hypertension considers five distinct groups. Transthoracic echocardiography represents the first and most important noninvasive screening tool for estimating the probability of pulmonary hypertension. The diagnostic approach to pulmonary hypertension is supported by a proposed algorithm, which identifies the underlying cause...

REVIEW
Xavier Monnet, Jean-Louis Teboul
BACKGROUND: For complex patients in the intensive care unit or in the operating room, many questions regarding their haemodynamic management cannot be answered with simple clinical examination. In particular, arterial pressure allows only a rough estimation of cardiac output. Transpulmonary thermodilution is a technique that provides a full haemodynamic assessment through cardiac output and other indices. MAIN BODY: Through the analysis of the thermodilution curve recorded at the tip of an arterial catheter after the injection of a cold bolus in the venous circulation, transpulmonary thermodilution intermittently measures cardiac output...

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...

High mitral inflow early (E) velocity to tissue Doppler E' ratio (E/E') and an E to late diastolic filling velocity ratio (E/A) are used to evaluate left ventricular (LV) diastolic function and filling pressure, but the usefulness of combined assessment of E/E' and E/A is not fully understood. Methods: We retrospectively analyzed 1,266 patients who underwent echocardiography to assess cardiac function. Patients were grouped based on the values of E/E' (low E/E'<15, high E/E'≥15) and E/A (low E/A≤0...
