A Successful Heart Transplantation Coupled with Temporary Right Ventricular Assist Device Implantation in a Patient with (ir)Reversible Pulmonary Hypertension.

Pulmonary hypertension (PH) constitutes one of the main contraindications to heart transplantation (OHT), and elevated pulmonary vascular resistance (PVR) is associated with high risk of posttransplant right heart failure (RVF). In the present case report, a patient with PH is introduced who qualified for heart lung transplantation (HLT) and underwent successful OHT with temporary right ventricle assist device (tRVAD) due to the lack of a suitable heart-lung donor. Temporary RVAD support coupled with optimal medical management may help reverse pulmonary vascular resistance, which was previously deemed as permanent in patients requiring heart transplantation.

A systematic approach to transoesophageal echocardiography in the intensive care unit - a practical guide for intensivists.

Transoesophageal echocardiography (TOE) has become a useful diagnostic and monitoring tool in critical care settings, especially when transthoracic echocardiography is difficult to perform. It gives valuable information in mechanical ventilation, especially in the prone position, in obese patients, and in patients with surgical dressings and chest tubes. Transthoracic echocardiography allows visualization of deep cardiac structures and their pathologies. It has extensive diagnostic implications. This article describes the systematic approach to critical care TOE examination with a detailed description of the views necessary for rapid haemodynamic assessment in critical care patients. It is concordant with European Diploma in Advanced Echocardiography (EDEC) requirements, and its structural approach is based on the author's experience acquired in the EDEC examination process. Performing TOE in an organized fashion can help to pinpoint most of the pathologies and monitor the treatment process in the intensive care unit.

Severe Acute Respiratory Distress Syndrome in Potential Organ Donors-Rescue Prone Positioning: A Case Report.

Organ transplantation is a recognized treatment for many critical organ insufficiencies. One of the main problems in transplantation is the mismatch between organ donation and demand. It is very important to improve donor eligibility after brain stem death and to minimize insult to donatable organs by appropriate donor management. We present prone positioning as an effective supportive method of organ optimization in patients with acute respiratory distress syndrome with severe hypoxemia and hemodynamic instability.

Utility of tissue Doppler imaging of systolic function to diagnose diastolic dysfunction in critically ill patients.

BACKGROUND: Diastolic dysfunction might be associated with increased mortality in severe sepsis and septic shock. In 2016 new American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) guidelines were published. They simplify our approach to diastolic dysfunction recognition, but they were not validated in critical care settings. The aim of the study was to assess the applicability of systolic tissue Doppler imaging of left ventricle in patients with and without diastolic dysfunction classified on the basis of the new guidelines. METHODS: Two echocardiographers analyzed transthoracic echocardiography (TTE) exa-minations and assigned patients according to ASE/EASCVI guidelines to three groups: patients with systolic dysfunction and diastolic dysfunction, patients with normal systolic function and diastolic dysfunction, and patients with normal systolic and diastolic function. RESULTS: We performed 593 examinations in 320 patients and 390 examinations in 200 patients were included in the study. In 264 examinations with ejection fraction (EF) < 55% systolic and diastolic dysfunction was diagnosed (group 1). In 114 examinations with EF ≥ 55% normal systolic and diastolic function was diagnosed (group 2). In 12 examinations with EF ≥ 55% normal systolic and abnormal diastolic dysfunction was diagnosed (group 3). After analyzing mean systolic tissue Doppler of the mitral annulus we found a statistically significant difference between group 1 and 2 (P < 0.0001) and between group 2 and 3 (P < 0.0001). The difference in values of means in group 1 vs. 3 was not statistically significant (P = 0.853). CONCLUSION: Systolic tissue Doppler analysis of mitral annulus might help to diagnose diastolic dysfunction especially in patients with preserved ejection fraction.

Clinical effectiveness of MARS treatment - multidirectional analysis of positive clinical response to treatment.

AIM OF THE STUDY: Liver failure is a life-threatening condition which often requires intensive care treatment. It is essential to quickly determine whether there are indications for extracorporeal liver support systems for the patient. The aims of the study were: to assess effectiveness of molecular adsorbent recirculating system (MARS) therapy based on selected clinical criteria, to analyze the moment of clinical response and to create a patient's profile, who will benefit clinically from the treatment. MATERIAL AND METHODS: The analysis encompassed medical histories of 65 patients treated with MARS. Effectiveness of treatment was evaluated based on selected clinical parameters. Statistical analysis was performed based on medical data gathered. RESULTS: There were 158 cycles of MARS performed, with effectiveness documented in 57 cycles (36.6%). The first MARS session was effective in 43.1% of patients. They also more often responded to the second cycle (63.6% vs. 15.4%). A significant part of the analysis was devoted to create a profile of the patient in whom positive response can be expected. A low MELD score and low baseline white blood cells (WBC) level are statistically significant factors in multivariate analysis of selected features of positive clinical response to treatment. CONCLUSIONS: MARS therapy is an effective form of treatment in a properly selected group of patients with liver failure. The first MARS session is the most effective one. It is also a good prognostic factor for further clinical response to treatment. Multifactorial analysis of positive clinical response to treatment enables to create a patient's profile based on the lower baseline MELD score and WBC.

Effectiveness and Safety Assessment of Citrate Anticoagulation During Albumin Dialysis in Comparison to Other Methods of Anticoagulation.

Liver failure is a serious and often deadly disease often requiring MARS (Molecular Adsorbent Recirculating System) therapy. Choosing the safe and effective method of anticoagulation during artificial liver support systems seems to be very difficult and extremely important. The aim of this study was to assess effectiveness and safety of regional anticoagulation with citrate in liver failure patients during MARS. We used a single center observational study. We analyzed 158 MARS sessions performed in 65 patients: 105 (66.5%) sessions in 41 patients with heparin anticoagulation, 40 (25.3%) sessions in 19 patients with citrate, and 13 (8%) sessions in only five patients without anticoagulation, that were excluded from part of the analysis. To determine the effectiveness of regional anticoagulation with citrate, probability of filter survival and changes in laboratory parameters were analyzed according to the applied method of anticoagulation. The safety of citrate was determined by Ca/Ca2+ ratio, acid-base balance, bleeding complications, and the need for blood product transfusions. The probability of filter survival in the citrate group was 94% and in the heparin group 82% (P = 0.204). There was no relationship between the method of anticoagulation and effectiveness of MARS therapy in lowering the levels of the analyzed parameters. Only one patient had a Ca/Ca2+ ratio higher than he safety margin. There were no statistically significant changes in pH and lactate level irrespective of anticoagulation; bicarbonate dropped significantly only in the heparin group (P = 0.03). The frequency of bleeding complications and the need for transfusions did not differ significantly between groups. Regional anticoagulation with citrate can be an effective and safe method of anticoagulation during MARS therapy, but requires attentive monitoring and further studies in liver failure patients.

Utility of transthoracic echocardiography (TTE) in assessing fluid responsiveness in critically ill patients - a challenge for the bedside sonographer.

Transthoracic echocardiography (TTE) has become one of the most important diagnostic tools in the treatment of critically ill patients. It allows clinicians to recognise potentially reversible life-threatening situations and is also very effective in the monitoring of the fluid status of patients, slowly substituting invasive methods in the intensive care unit. Hemodynamic assessment is based on a few static and dynamic parameters. Dynamic parameters change during the respiratory cycle in mechanical ventilation and the level of this change directly corresponds to fluid responsiveness. Most of the parameters cannot be used in spontaneously breathing patients. For these patients the most important test is passive leg raising, which is a good substitute for fluid bolus. Although TTE is very useful in the critical care setting, we should not forget the important limitations, not only technical ones but also caused by the critical illness itself. Unfortunately, this method does not allow continuous monitoring and every change in the patient's condition requires repeated examination.
