We report a case of large paradoxical embolisms through a patent foramen ovale in a patient with acquired heparin-induced thrombocytopenia type II (HIT). One large ventricular thrombus embolizing through the aortic valve was documented on videotape for the first time while performing transesophageal echocardiography. A 56-year-old man was admitted with acute respiratory failure initially believed to have an exacerbated chronic obstructive pulmonary disease. Arterial oxygen saturation was only 33%. He received antibiotic and anti-obstructive treatments and was mechanically ventilated for 7 days. Few hours after extubation, he developed recurrent severe dyspnea accompanied by acute pain and pulselessness in his left leg. Transthoracic echocardiography revealed an enlarged right ventricle and suggested the presence of free-floating thrombi both in the right and in the left-heart cavities. During transesophageal echocardiography, a large serpentine left-heart thrombus embolized through the aortic valve and disappeared. The patient developed ventricular fibrillation and underwent successful cardiopulmonary resuscitation including emergency thrombolysis with alteplase. Four hours later, the surgeon retrieved a 20-cm long thrombus from the left femoral artery.

Coronary occlusion and pulmonary embolism are responsible for the majority of cases of out-of-hospital cardiac arrest (OHCA). Despite previous favourable results of pre-hospital fibrinolysis in cases of OHCA, the benefit could not be confirmed in a large controlled study using the fibrinolytic tenecteplase. For reteplase (r-PA), there are hardly any data regarding pre-hospital fibrinolysis during ongoing resuscitation. The present study reported results using r-PA therapy in a German physician-supported Emergency Medical Services system. The data of OHCA patients who received pre-hospital fibrinolytic treatment with r-PA after an individual risk/benefit assessment were retrospectively analysed. To assess the effectiveness of this approach, the rate of patients with a return of spontaneous circulation (ROSC) was compared with the corresponding figure that was calculated with the help of the RACA (ROSC after cardiac arrest) score. The RACA algorithm predicts the probability of ROSC based on data from the German Resuscitation Registry. Further outcome data comprised hospital discharge rate and neurologic status at discharge. From 2001 to 2009, 43 patients (mean age, 58.5 years; 65.1% male; 58.1% ventricular fibrillation) received r-PA. Of these, 20 patients (46.5%) achieved ROSC, compared to a probability of 49.8% according to the RACA score (P=0.58). A total of 8 patients (18.6%) were discharged alive, including 5 (11.2%) with a good neurological outcome. For the analysed small patient collective, pre-hospital r-PA did not offer any benefits with regard to the ROSC rate. Further analyses of larger patient numbers on a nationwide registry basis are recommended.

Aim To evaluate a correlation of serum level of neutrophil gelatinase-associated lipocalin (NGAL) to the risk of the occurrence of complications in patients with the early phase of ST-segment elevation myocardical infarction (STEMI) treated with fibrinolytic therapy prior to percutaneous coronary intervention (PCI). Methods A total of 54 patients with the diagnosis of STEMI treated with fibrinolytic therapy (alteplase) prior to PCI were included. Patients were admitted to the Intensive Care Unit (ICU) of Clinic for Heart, Blood Vessel and Rheumatic Diseases in the period January to March 2018. All patients underwent coronary angiography and PCI within the maximum of 48 hours delay after fibrinolysis, according to the hemodynamic and electrical stability and PCI availability. Blood samples were taken immediately after admission prior to fibrinolytic administration. Patients were divided into two groups according to NGAL values (less or more than 134.05 ng/mL). Results Higher values of NGAL have effect on a higher mean systolic and diastolic pressure (p=0.001 and p=0.003, respectively). Patients with higher NGAL values also have higher values of brain natriuretic peptide (p=0.0001) and highly sensitive troponin I (p=0.002). In that group relative risk (RR) for lethal outcome was 6.4 times significantly higher (p=0.002), for the development of heart failure 2.88 times (p=0.0002), for post-myocardial infarction angina pectoris 2.24 times (p=0.0158), and for ventricular rhythm disturbances (ventricular tachycardia, ventricular fibrillation) 1.96 times higher (p=0.0108). Conclusion Increased NGAL value is related to an unfavourable outcome of patients in the early phase of STEMI treated with fibrinolytic therapy prior to PCI.
