BACKGROUND: Left ventricular assist devices (LVADs) require serial assessment of right and left ventricular (RV & LV) volumes and function. Because the RV is not assisted, its function is a critical determinant of the hemodynamic and contributes significantly to postoperative morbidity and mortality. We evaluated the feasibility and the accuracy of tomographic-equilibrium radionuclide ventriculography (t-ERV) for the assessment of patients with LVADs. METHODS: Twenty-four patients with LVAD underwent t-ERV...

BACKGROUND AND OBJECTIVES: The aim of this retrospective study was to analyze differences in the initial hemodynamic assessment and its impact on the treatment in patients aged 80 years or older compared to younger patients during the first 6 h after admission to the medical intensive care unit (ICU). RESULTS: We analyzed 615 consecutive patients admitted to the medical ICU of which 124 (20%) were aged 80 years or more. The older group had a significantly higher acute physiology and chronic health evaluation (APACHE II) score, an overall mortality in the ICU and a presence of pre-existing cardiac disease...

BACKGROUND: Transition from an asymptomatic to symptomatic state in severe aortic stenosis is often difficult to assess. Identification of a morphological sign of increased hemodynamic load may be important in asymptomatic aortic stenosis to identify patients at risk. METHODS AND RESULTS: Thirty-nine patients with asymptomatic severe aortic stenosis (aortic valve area <1 cm(2), peak jet velocity >3.5 m/s) underwent exercise testing with simultaneous invasive hemodynamic monitoring and Doppler echocardiography...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. iNO lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure. METHODS: A hemorrhagic shock and pneumonectomy model was developed using sheep...

Right ventricular (RV) failure after cardiac surgery is associated with an ominous prognosis. The aetiology of RV failure is multifaceted and the ability to recognize RV failure early is paramount in order to initiate timely treatment. The present review focuses on different diagnostic modalities for RV function and discusses the normal versus abnormal findings in RV monitoring after cardiac surgery and the limitations of the applicable diagnostic modalities. There are specific challenges in RV assessment after cardiac surgery due to a loss of longitudinal contraction and a concomitant gain of transverse contraction...

Thoracic aortic aneurysms rupture and dissection are among the most devastating vascular diseases, being characterized by elevated mortality, despite improvements in diagnostic imaging and surgical techniques.An increased aortic root diameter (ARD) represents the main risk factor for thoracic aortic dissection and rupture and for aortic valve regurgitation.Even though arterial hypertension is commonly regarded as a predisposing condition for the development of thoracic aorta aneurysms, the role of blood pressure (BP) as determinant of aortic root enlargement is still controversial...

Tetralogy of Fallot (TOF) is one of the most common cyanotic congenital heart diseases. With surgical repair and the advances in postoperative care, contemporary mortality has dramatically improved and an increasing number of patients survive into adulthood, leading to a growing number of adult TOF. However, residual anatomic and hemodynamic abnormalities are encountered in nearly all patients, making follow-up mandatory. Furthermore, mortality starts to increase 25 years after surgery, emphasizing that, in adult TOF, closer monitoring is necessary...

Echocardiography as an imaging method in anaesthesia and intensive care medicine has enabled a new dimension of hemodynamic monitoring: the direct visualization of the cardiac function and its disruptions. Preconditions for a broad application in this area was the development of mobile, high-definition ultrasonic devices and the origination of focused examination techniques. A successful application of this method requires the respective know-how of the examiner, in order to take relevant decisions and avoid misdiagnoses...

BACKGROUND: The aim of this study was to evaluate the effect of exercise training on cardiac function in heart failure (HF) patients recently suffering from acute decompensation. Radionuclide ambulatory ventricular function monitoring (VEST) was used to detect variations in cardiac hemodynamics during training period. METHODS: This was a monocentric, randomized, controlled trial. We enrolled 72 HF patients [left ventricle ejection fraction (LVEF) <40%] within two weeks after acute cardiogenic pulmonary edema: 40 in the elderly group, 32 in the middle-aged group...

A reliable estimation of cardiac preload is helpful in the management of severe circulatory dysfunction. The estimation of cardiac preload has evolved from nuclear angiography, pulmonary artery catheterization to echocardiography, and transpulmonary thermodilution (TPTD). Global end-diastolic volume (GEDV) is the combined end-diastolic volumes of all the four cardiac chambers. GEDV has been demonstrated to be a reliable preload marker in comparison with traditionally used pulmonary artery catheter-derived pressure preload parameters...

BACKGROUND: Pericardial decompression syndrome is defined as paradoxical hemodynamic instability, left ventricular or bi ventricular systolic dysfunction and pulmonary edema after pericardial fluid drainage. Pericardial Decompression Syndrome is an unexpected clinical scenario with an incidence less than 5% in all surgically or percutaneously managed pericardial tamponade patients. The aim of this manuscript was to describe a case with cardiac tamponade in whom acute biventricular heart failure and pulmonary edema developed after surgical creation of a pericardial window, and to discuss this case in light of the literature...

Neurogenic pulmonary edema (NPE) is occasionally observed in patients with traumatic brain injury (TBI); however, this condition is often underappreciated. NPE is frequently misdiagnosed due to its atypical clinical performance, thus delaying appropriate treatment. A comprehensive management protocol of NPE in patients with TBI has yet to be established. The current study reported the case of a 67-year-old man with severe TBI who was transferred to our intensive care unit (ICU). On day 7 after hospitalization, the patient suddenly suffered tachypnea, tachycardia, systemic hypertension and hypoxemia during lumbar cistern drainage...

Wojciech Mądry, Maciej Aleksander Karolczak
In this paper, the authors attempt to concisely present the anatomical and pathophysiological bases as well as the principles for echocardiographic evaluation of mechanical aspects of cardiac function based on speckle tracking method. This technique uses a phenomenon involving the formation of characteristic image units, referred to as speckles or acoustic markers, which are stable during cardiac cycle, on a two-dimensional echocardiographic picture. Changes in the position of these speckles throughout the cardiac cycle, which are monitored and analyzed semi-automatically by a computer system, reflect deformation of both, cardiac ventricle as a whole as well as its individual anatomical segments...

Giant cell myocarditis (GCM) is a rare and commonly fatal form of fulminant myocarditis. During the acute phase, while immunosuppressive therapy is initiated, venoarterial extracorporeal membrane oxygenation (VA-ECMO) support is commonly used as a bridge to heart transplantation or recovery. Until recently, conventional transesophageal echocardiography and transthoracic echocardiography were the tools available for hemodynamic assessment of patients on this form of mechanical circulatory support. Nevertheless, both techniques have their limitations...

INTRODUCTION: As a common morphological change of aging heart, sigmoid ventricular septum is frequently found during routine preoperative evaluation, but often disregarded because of its little clinical importance. However, in this report, we describe a 70-year old patient with sigmoid ventricular septum who developed severe hemodynamic deterioration during liver transplantation because of its unique morphology of heart. METHODS: During the course of reperfusion of the graft, patient's hemodynamics were closely monitored using transesophageal echocardiography...

Echocardiography is pivotal in the diagnosis and management of the shocked patient. Important characteristics in the setting of shock are that it is non-invasive and can be rapidly applied.In the acute situation a basic study often yields immediate results allowing for the initiation of therapy, while a follow-up advanced study brings the advantage of further refining the diagnosis and providing an in-depth hemodynamic assessment. Competency in basic critical care echocardiography is now regarded as a mandatory part of critical care training with clear guidelines available...

Joel Wilken
Palpitations are a symptom of many cardiac and noncardiac conditions. The patient's history, physical examination, appropriately directed laboratory tests, and basic electrocardiogram are helpful in evaluating palpitations and may be essential to finding a diagnosis. There are many outpatient options for the evaluation of palpitations caused by a presumed cardiogenic cause. These evaluation tools include Holter monitor, event monitor, transtelephonic electrocardiographic monitor, treadmill exercise stress test, echocardiography, and electrophysiologic studies...

Dynamic echocardiographic monitoring in rats subjected to forced alcoholization showed the formation of disorders in intracardiac hemodynamics characteristic of ethanol cardiomyopathy formed by the end of 24-week continuous ethanol consumption. The results of echocardiographic monitoring were confirmed by histological and morphometric studies demonstrating fatty infiltration of the myocardium pathognomonic for this condition and bifocal dilatation of cardiac ventricles. These results persuasively demonstrate that echocardiographic studies on small animals are valid and can be used for search for cardiotropic drugs and studies of the mechanisms of their activities...
