BACKGROUND: Pulmonary embolism (PE) is a common and potentially life-threatening diagnosis when a certain amount of thrombotic mass obstructs blood flow through the pulmonary circulation. The finding of acute and subacute ischaemic foci on magnetic resonance imaging (MRI) of the brain in a group of patients with this diagnosis in whom we demonstrate the presence of patent foramen ovale (PFO) by transoesophageal echocardiography (TEE) is surprisingly high. METHODS: A total of 129 patients with a diagnosis of pulmonary embolism (confirmed by computed tomography with contrast agent, CTA) who consented to further examination were examined by transthoracic echocardiography (TTE) and transoesophageal echocardiography (TEE) with contrast agent, underwent magnetic resonance imaging of the brain according to a specific protocol, and underwent a comprehensive baseline laboratory examination. RESULTS: In our group of 129 patients, we found the presence of PFO in 36.4% (n=47) of them. A total of 5.4% (n=7) patients had asymptomatic acute and subacute ischaemic changes on brain MRI; 6 of them had concomitant PFO. The statistically significant correlation between troponin levels and the presence of pathological findings on MRI and the trend of a similar correlation for NT-proBNP values is also very interesting finding. CONCLUSIONS: The association between the presence of PFO and the occurrence of symptomatic or asymptomatic findings on brain MRI is a well-known fact (the issue of paradoxical embolism) but the high frequency of acute and subacute lesions on brain MRI in the group of patients with a diagnosis of acute PE is surprising.

INTRODUCTION: Up to 50% of patients with ST elevation myocardial infarction (STEMI) have ≥ 50% stenosis in a major non-infarct-related artery. Several studies have evaluated the prognostic value of the completion of revascularization with overall inconclusive results. Selection of the stenoses was based on the angiographic evaluation, invasive hemodynamic measurement or the combined approach. It is unknown whether such a selection provides correlation of comparable patient groups. MATERIAL AND METHODS: We enrolled 51 patients (62.7 ±10.2 years) with acute STEMI and at least one residual (50-90%) stenosis in a non-infarct-related major coronary artery (excluding left main coronary artery). Overall 65 stenoses (67.9 ±10.7%) were evaluated angiographically following primary percutaneous coronary intervention and the hemodynamic significance was estimated with respect to the stenosis severity, caliber of the arterial segment, localization of the stenosis (proximity) as well as the estimated size of the supplied vascular territory. During subsequent hospitalization, invasive measurement of the hemodynamic significance using fractional flow reserve (FFR) was performed to guide the final revascularization strategy (FFR value of ≤ 0.80 considered significant). RESULTS: Based on angiographic evaluation, a total of 44 stenoses would be recommended for treatment, whereas only 31 stenoses were revascularized based on FFR measurement. Moreover, visual evaluation and hemodynamic measurement were discrepant in 27 of 65 (41.5%) stenoses. CONCLUSIONS: We observed a weak correlation between visual angiographic evaluation and invasive hemodynamic measurement. More stents would be implanted based on angiographic evaluation compared to FFR measurement.

Atherosclerosis is the most common cause of coronary steno-occlusive disease and acute myocardial infarction is the leading cause of death in industrialized countries. In patients with acute ST elevation myocardial infarction (STEMI), there is unquestionable evidence that primary percutaneous coronary intervention providing recanalization of the infarct related artery (IRA) is the preferred reperfusion strategy. Nevertheless, up to 50% of patients with STEMI have multivessel coronary artery disease defined as at least 50% stenosis exclusive of IRA. There is conflicting data regarding the optimal treatment strategy and timing in such patients. Currently, it is assumed that stable patients might benefit from complete revascularization particularly in reducing the need for future unplanned procedures but only culprit lesion should be treated during index procedure in unstable patients. In this article, we provide a comprehensive overview of this important and currently highly debated topic.

AIMS: Growth differentiation factor 15 (GDF15) shows potential predictive value in various cardiac conditions. We investigated relationships between GDF15 and clinical or procedural outcomes in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) in order to propose clinically useful predictive risk stratification model. METHODS: This prospective single-center registry enrolled 88 consecutive patients with severe symptomatic aortic stenosis treated with TAVI. Clinical parameters were collected and biomarkers including GDF-15 were measured within 24 h before TAVI. All relevant clinical outcomes according to the Valve Academic Research Consortium-2 were collected over the follow-up period. RESULTS: The cohort included 52.3% of females. The mean age of study participants was 81 years; the mean Society of Thoracic Surgeons (STS) score and logistic EuroSCORE were 3.6% and 15.4%, respectively. The mortality over the entire follow-up period was 10.2%; no death was observed within the first 30 days following TAVI. Univariate analysis showed significant associations between GDF15 and mortality (P=0.0006), bleeding (P=0.0416) and acute kidney injury (P=0.0399). A standard multivariate logistic regression model showed GDF-15 as the only significant predictor of mortality (P=0.003); the odds ratio corresponding to an increase in GDF15 of 1000 pg/mL was 1.22. However, incremental predictive value was not observed when the STS score was combined with GDF15 in this predictive model. CONCLUSIONS: Based on our observations, preprocedural elevated GDF15 levels are associated with increased mortality and demonstrate their additional value in predicting adverse clinical outcomes in a TAVI population.

AIMS: Here, we report a case of very late (70+ days) development of pseudoaneurysm on the site of sheath insertion in a 60- year old woman. METHODS: The patient underwent cardiac catheterization using transradial approach. RESULTS: Despite the transradial approach, which is generally considered as a suitable prevention of this problem, and despite absence of any periprocedural complications, the patient developed a pseudoaneurysm after more than 70 days from the procedure. CONCLUSIONS: In some cases, a pseudoaneurysm may develop extremely late after cardiac catheterization. Such an extremely late development of pseudoaneurysm has not been described in literature so far.
Paradoxical embolism is one of the predominant causes of cryptogenic stroke and interventional secondary prevention, i.e., closure of the patent foramen ovale (PFO), is a much discussed issue. This review aims to provide a complex perspective on this topic, aggregates and comments on the available data and current guidelines. Several large trials were performed, some of which proved the superiority of PFO closure over pharmacotherapy while others have not. Studies detecting significant superiority of intervention worked with disproportionately high representation of large shunts compared to the general population. Other controversies also remain, such as the lack of comparison of the effect of modern anticoagulant/antiplatelet treatment to PFO closure or the risk of developing unwanted side effects after intervention, and these are discussed in detail. PFO closure is a suitable method for secondary prevention of paradoxical embolism and, therefore, cryptogenic stroke. However, this is only true for carefully selected patient populations and such selection is of the utmost importance in deciding on interventional or conservative treatment.

The development of left ventricular thrombus (LVT) is a well-known and serious complication of acute myocardial infarction (AMI) due to the risk of systemic arterial embolism (SE), which is variable in its clinical picture and has potentially serious consequences depending on the extent of target organ damage. SE results in an increase in mortality and morbidity in these patients. LVT is one of the main causes of the development of ischaemic cardio-embolic cardiovascular events (CVE) after MI and the determination of the source of cardiac embolus is crucial for the initiation of adequate anticoagulant therapy in secondary prevention. Echocardiography holds an irreplaceable place in the diagnosis of LVT, contrast enhancement provides higher sensitivity. The gold standard for LVT diagnosis is cardiac magnetic resonance imaging, but it is not suitable as a basic screening test. In patients with already diagnosed LVT, it is necessary to adjust antithrombotic therapy by starting warfarin anticoagulation for at least 6 months with the need for echocardiographic follow-up to detect thrombotic residues. The effect of prophylactic administration of warfarin in high-risk patients after anterior AMI does not outweigh the risk of severe bleeding complications and does not result in a decrease in mortality and morbidity. At the present time, there is not enough evidence to use direct oral anticoagulants in this indication.
