UNASSIGNED: Near-fatal asthma (NFA) is a severe condition that can lead to respiratory arrest or high carbon dioxide levels, often requiring mechanical ventilation. Biologics have revolutionized the management of severe asthma, significantly improving symptom severity, reducing the number of exacerbations and hospitalizations, and decreasing the need for oral corticosteroids. However, their effectiveness in acute settings, particularly for ICU patients experiencing severe respiratory failure, is not well-studied. More research is needed to determine if biologics can improve recovery during severe asthma exacerbations.
UNASSIGNED: We report a case of NFA in a patient with severe allergic eosinophilic asthma, who experienced global respiratory failure necessitating hospitalization, intubation, and veno-venous extracorporeal membrane oxygenation (VV-ECMO). Given the severity of the clinical condition, compassionate administration of Benralizumab, which targets the IL-5 receptor, was attempted.
UNASSIGNED: Five days from anti-IL5 receptor treatment start, the patient was extubated and the ECMO stopped. After the stepdown to the respiratory intensive care unit (RICU), the patient was weaned from oxygen therapy and subsequently discharged from hospital.
UNASSIGNED: Benralizumab demonstrated rapid effectiveness in improving respiratory failure leading to successful weaning from VV-ECMO and subsequent extubation.

Tapeworms of the genus Echinococcus cause parasitic disease in humans through the ingestion of eggs in contaminated food and water. Rupture of slowly enlarging cysts in the liver, lungs, and other organs can be life-threatening and many deaths are recorded yearly worldwide. Surgery and removal of such cysts remain the most effective treatment. Veno-venous extracorporeal membrane oxygenation (ECMO) routinely placed in the ICU in patients with acute respiratory distress syndrome (ARDS), may provide time and adequate oxygenation for the completion of surgery in echinococcosis cases. In this article, we present a rare case of pulmonary echinococcosis in a young patient requiring ECMO support prior to surgery.

Background and Objective: Although extracorporeal membrane oxygenation (ECMO) is an essential life-saving technique for patients with refractory cardiopulmonary shock, it can be fatal in certain cases. Case Presentation: A 19-year-old girl treated with ECMO presented with acute limb ischemia 2 days after cannula removal. The decannulation was performed percutaneously by an interventional cardiologist, and the vascular surgery department was consulted after the patient developed symptoms. The first suspected diagnosis was thrombosis due to incorrect use of the closure device. However, the artery had ruptured due to the insertion of a catheter with a cannula that was larger than the patient\'s artery. Management and Outcome: Fortunately, excessive bleeding due to the size-mismatched cannula was prevented by an unintentional complication of the closing device, which saved the patient\'s life. She underwent a right common femoral artery thrombectomy and patch angioplasty. Hospital guidelines have changed regarding the surgical removal of ECMO cannulas. Discussion: This report aims to highlight the importance of two aspects that are critical to a successful outcome: individualized cannula selection followed by precise insertion and removal and postoperative evaluation of a patient\'s final status.

UNASSIGNED: Restrictive cardiomyopathy (RCM) represents a rare cardiovascular disorder stemming from filament-associated genes. Nonetheless, treating RCM presents considerable challenges, particularly concerning device implantation and mechanical support. Furthermore, elucidating the molecular function of specific variants holds promise in benefiting patients and enhancing prognosis, given the significant heterogeneity among RCM variants.
UNASSIGNED: The proband, an eight-year-old female, was admitted to our hospital post cardiopulmonary resuscitation due to sudden cardiac arrest. Echocardiography revealed bilateral atrial enlargement. Whole-exome sequencing uncovered a novel heterozygous mutation (c.509G>A, p.R170Q) in TNNI3. Evaluation using the MutationTaster application deemed c.509G>A pathogenic (probability = 0.99). Following clinical manifestations, imaging assessments, and genetic screening, the proband received an RCM diagnosis. ECMO was recommended along with continuous renal replacement therapy. However, persistent atrial flutter ensued post-ECMO withdrawal. Attempts to restore cardiac rhythm with cardioversion, metoprolol, and amiodarone proved futile. Subsequent heart failure led to the patient\'s demise due to cardiac shock. Based on crystal protein structural analysis, we observed that cTnI-R170Q and R170W exerted similar impacts on protein structural stability and formation. However, both differed significantly from cTnI-R170G, primarily influencing amino acid regions 32-79 and 129-149, involved in TnC and actin binding. Therefore, cTnI-R170Q was revealed to induce RCM via the same molecular mechanism as cTnI-R170W.
UNASSIGNED: Managing RCM remains a critical challenge. This study underscores the discouragement of device implantations for cardiac pump functional support in RCM, particularly for non-short-term scheduled HTx. Additionally, considering catheter ablation for atrial fibrosis-induced AFs is recommended. Mechanistically, cTnI-R170Q primarily diminishes troponin-actin interactions and destabilizes thin filaments.

UNASSIGNED: Acute pulmonary embolism (APE) is a common and potentially fatal cardiovascular disease that can lead to sudden cardiac arrest in severe cases. When conventional cardiopulmonary resuscitation measures fail to achieve the return of spontaneous circulation (ROSC) in patients with APE, venoarterial extracorporeal membrane oxygenation (ECMO) becomes a viable therapeutic option. As an advanced life support treatment, ECMO ensures the perfusion of critical organs, providing sufficient time for interventions necessary for ROSC.
UNASSIGNED: We report the case of a patient who experienced cardiac arrest due to pulmonary embolism. During the treatment, the patient received two sessions of external cardiopulmonary resuscitation (ECPR) as supportive care and experienced cerebral hemorrhage. Ultimately, the patient improved and was discharged following support from extracorporeal membrane oxygenation (ECMO), careful anticoagulation strategies, and intervention with balloon pulmonary angioplasty.
UNASSIGNED: ECMO can serve as an important life support technology for patients with severe APE. Through a cautious anticoagulation therapy, not only was the ECMO support successfully maintained but also was further deterioration of cerebral hemorrhage effectively prevented. For patients with concurrent main pulmonary artery embolism and bleeding, balloon pulmonary angioplasty may be an option.

UNASSIGNED: The use of mechanical circulatory support (MCS) has markedly increased over the last decade, so have the inter-hospital transfers, with the aim of being able to offer advanced heart failure (AHF) therapies and centralizing patients to tertiary centres.
UNASSIGNED: In this article, we present the first in Europe long-distance air transfer of a patient supported by veno-arterial extracorporeal membrane oxygenator and Impella (ECPELLA), as a bridge to successful heart transplant. In our case report, a foreign young patient with AHF due to familiar cardiomyopathy required multiple MCS devices to achieve cardiovascular stability. After appropriate planning and multidisciplinary discussion, the patient was transferred on MCS to his country of origin via a fixed-wing airplane, in order to be assessed for heart transplantation. During take-off, the Impella flows temporarily dropped and a suction alarm was displayed; however, this rectified without intervention, and the rest of the flight was uneventful. One month after transfer, the patient underwent successful heart transplantation and remained clinically stable during the 12-month follow-up.
UNASSIGNED: Our experience links together the current challenges in the evolving AHF strategies and the increased need for inter-facility cooperation. Both these clinical and logistic challenges appear to lead to possible improved outcomes, after appropriate assessment, training, and accurate planning. Our experience provides useful information on feasibility of long-distance transport of patients supported by ECPELLA in Europe.

Acute respiratory syndrome caused by a novel coronavirus (SARS-CoV-2) in pregnant women can progress to a critical condition. In this paper, we present a case of a woman in the 28th week of gestation hospitalized due to respiratory insufficiency caused by COVID-19 infection and consequent bilateral pneumonia with development of severe acute respiratory distress syndrome. Noninvasive ventilation through a face mask was started but due to progression of respiratory insufficiency with high FiO2 and positive end expiratory pressure (PEEP), we decided to intubate the patient, after which obstetricians agreed to complete pregnancy by cesarean section. The clinical course was complicated by desaturation and bradycardia with recurring asystole which recovered after the use of atropine. The patient was increasingly difficult to mechanically ventilate on the PSIMV modality (tidal volume [TV] <200 mL). She was switched to ASV modality (TV up to a maximum of 350 mL, ASV 130%, PEEP 16 cm H2O, FiO2 100%, RR 25/min, pPeak 35 cm H2O, pPlateau 35 cm H2O), after which peripheral saturation recovered to 89%. Due to inadequate mechanical ventilation, the patient was transferred to Dr. Fran Mihaljević University Hospital for Infectious Diseases in order to perform extracorporeal membrane oxygenation (ECMO). Owing to all of the measures taken, recovery followed after 13 days on ECMO.

Re-expansion pulmonary edema is defined as pulmonary edema that occurs when a chronically collapsed lung rapidly re-expands, most commonly following chest tube placement for pneumothorax, re-expansion of severe atelectasis, and evacuation of pleural effusion. Though it is very rare, the sudden onset and clinical features of re-expansion pulmonary edema make it a lethal complication that requires urgent treatment. We present a 60-year-old patient who underwent an aortic valve replacement with pre-existing large bilateral pleural effusions. Intraoperatively, upon evacuation of the pleural effusions, the patient developed worsening lung compliance, refractory hypoxemia, and hypercapnia that required emergent veno-venous extracorporeal membrane oxygenation support.

UNASSIGNED: Intravenous administration of azithromycin has been linked to severe hypotension in some case reports in the past. We report a further case of profound shock requiring excessive use of vasopressors and extracorporeal membrane oxygenation (ECMO).
UNASSIGNED: An 18-year-old Caucasian male was admitted due to fulminant myocarditis and signs of cardiogenic shock. He had to be put on venoarterial ECMO only hours after admission. Due to the occurrence of disseminated intravascular coagulation and heparin-induced thrombocytopenia, haemodynamic support was discontinued on Day 8. On Day 11 of his stay, the patient started to exhibit signs of severe infection and a single 1500 mg dose of azithromycin was prescribed. Immediately after starting the infusion, the patient developed profound hypotension and signs of cardiogenic shock. Consecutively, venoarterial ECMO had to be re-established, and the azithromycin infusion was stopped in the process. It took the restart of the compound to recognize the connection between the administration of the therapy and the occurrence of cardiogenic shock. After discontinuing azithromycin, no further sudden hypotensive episodes were recorded, and the patient received left ventricular assist device implantation as a bridge to recovery or transplant.
UNASSIGNED: Rapid-onset hypotension appears to be a very rare but important adverse drug reaction associated with intravenous administration of azithromycin. Factors such as preceding infection and reduced biventricular function may facilitate the described occurrence.
