An Unexpected Diagnostic Twist in an Elderly Patient: No Heart Failure With Preserved Ejection Fraction.

Heart failure with preserved ejection fraction (HFpEF) is considered to be the dominant cause of dyspnea and pulmonary hypertension (PH) in elderly patients with preserved left ventricular systolic function and cardiovascular comorbidities. However, it is important to keep in mind that left ventricular diastolic dysfunction is not the only possible cause of PH in cases of late-onset clinical manifestation. A multiparametric approach is essential for accurate diagnosis and therapeutic decision-making. A 74-year-old patient was admitted due to progressive dyspnea and suspicion of PH. Given the patient's risk profile, HFpEF and concomitant post-capillary PH were anticipated. Despite negative findings on CT angiography and transesophageal echocardiography, right heart catheterization was performed, revealing discrepant oxygen saturations in the superior vena cava and right atrium. A partial anomalous pulmonary venous return and an atrial septal defect were identified through cardiac magnetic resonance imaging.

Pulmonary Artery Dilatation Due to Pressure or Volume Overload in Congenital Heart Disease.

Background: Pulmonary artery dilatation is described mostly in association with pulmonary hypertension. Patients/Methods: Study analysis: 60 patients with pulmonary arterial hypertension in congenital heart disease (PAH-CHD); 64 with repaired tetralogy of Fallot/pulmonary regurgitation (rTOF/PR); and 80 healthy (NORMAL). Measured were: main pulmonary artery (MPA) diameter and MPA/ascending aorta (Ao asc) ratio, by echocardiography (ECHO) and computer tomography or magnetic resonance imaging (CT/MRI). Results: In MPA diameter, significant differences between PAH-CHD, rTOF/PR, and NORMAL were found (median): 37 vs. 27 vs. 21 mm (p < 0.0001). In MPA/Ao asc ratio, there was a difference between PAH-CHD and NORMAL (median): 1.3 vs. 0.8 (p < 0.0001), but not between rTOF/PR and NORMAL: 0.74 vs. 0.8 (p = 0.3). Significant MPA dilatation (>40 mm) was present: in PAH-CHD, 35% (ECHO) and 76.9% (CT/MRI) of patients, while in rTOF/PR, 3.1% (ECHO) and 7.8% (CT/MRI). Severe MPA dilatation (>50 mm) occurred only in PAH-CHD: 16.7% (ECHO) and 31.4% (CT/MRI), while not in rTOF/PR. There was a significant correlation between ECHO and CT/MRI measurements, but ECHO was underestimated in all parameters. Conclusions: MPA dilatation due to pressure overload is more frequent and more severe; volume overload also leads to MPA dilatation but is less severe. The MPA/Ao asc ratio is not reliable for MPA dilatation estimation in rTOF/PR.

Complications after administration of mRNA vaccine against COVID-19 - case report and short review.

The pandemic of the disease COVID-19 (COronaVIrus Disease 2019) caused by the SARS-CoV-2 coronavirus (severe acute respiratory syndrome coronavirus 2) resulted in millions of deaths and many patients have chronic consequences after overcoming the acute condition. Several vaccines have been developed in an effort to stop the spread of the virus, but they have potentially serious adverse effects. We present a case report of a patient with acute (myocarditis, exacerbation of bronchial asthma) and long-term (postural orthostatic tachycardia syndrome - POTS) complications after vaccination with the second dose of mRNA vaccine BNT162b2 (Comirnaty®). Treatment consists of regimen measures, numerous pharmacotherapy (metoprolol, ivabradine, corticosteroids, antihistamines, antiphlogistics, bronchodilators) and several nutraceuticals (maritime pine bark extract, quercetin, vitamins, magnesium, phosphatidylcholine). In the discussion, we analyze post-vaccination injury and present a short review of the current literature.

Hypereosinophilic syndrome presenting with progressive cardiac cachexia: a case report.

Background: Hypereosinophilic syndrome (HES) is a rare haematologic disorder defined by persistent eosinophilia associated with organ damage. Cardiac involvement occurs in HES patients frequently and represents major cause of their morbidity and mortality. Case summary: A 66-year-old female patient underwent comprehensive cancer screening due to significant weight reduction. Screening showed negative results except for echocardiography, which revealed a large right ventricular mass imitating malignant cardiac tumour. Patient thus underwent biopsy of the intracardial mass. The procedure was complicated with right ventricular perforation causing cardiac tamponade, successfully resolved by immediate pericardiocentesis. Subsequent echocardiography revealed an echodense mass also in left ventricular apex, resembling a thrombus. Laboratory findings with mildly elevated eosinophil count and presence of formations in both ventricular apexes arose suspicion of non-malignant disease origin, specifically eosinophilic endomyocarditis. The presumption was supported by medical history of bronchial asthma, pansinusitis, and hypereosinophilia. Cardiac magnetic resonance (CMR) confirmed signs of eosinophilic endomyocarditis of both ventricles, together with presence of several intracardiac thrombi. However, despite intensive treatment, patient died due to progressive heart failure 3 months later. Discussion: As seen in our case, establishing diagnosis of eosinophilic endomyocarditis may represent a challenge in clinical practice, since it represents a rare disease with variable clinical manifestations. However, presence of formations in both ventricles together with peripheral eosinophilia should raise suspicion of this diagnosis. Our case also highlights the importance of CMR imaging in diagnostic process of eosinophilic endomyocarditis, since it represents a non-invasive diagnostic modality able to detect distinctive signs of eosinophilic endomyocarditis.

Lung Cancer Screening Initiative in Slovakia: Guidelines of screening implementation.

Lung cancer (LC) represents a major healthcare issue worldwide. It is the leading cause of cancer-related mortality in Slovakia and European Union. Data from multiple randomized controlled trials have shown significant evidence of a mortality benefit in LC using screening with low-dose computed tomography of the chest (LDCT). Therefore, European healthcare authorities, relevant expert societies, and professional organizations recommend implementing national LC screening (LCS) programs in their member countries. This article outlines the basic methodology, guidelines, and practical aspects of LCS implementation strategies in Slovakia. We describe fundamental principles to identify asymptomatic high-risk patients reduce false positive and false negative results, decrease benign resection rates, and avoid unnecessary invasive procedures. The efficacious utilization of public resources to secure the highest possible quality standards of LDCT plays a crucial role in successfully implementing a nationwide LCS program (Tab. 1, Fig. 4, Ref. 31).

Diagnostic performance of edited 2HG MR spectroscopy of central glioma in the clinical environment.

OBJECTIVE: Oncometabolite D-2-hydroxyglutarate (2HG) is pooled in isocitrate dehydrogenase (IDH)-mutant glioma cells. Detecting 2HG by MR spectroscopy (MRS) has been proven viable in the last decade but has not entirely found its way into the clinical routine. This study aimed to explore the adoption of 2HG MRS while acknowledging factors that influence its performance in the clinical environment. METHODS: Thirty-nine MR spectra were acquired and reported prospectively in patients with suspected glioma using a 3 T system with Mescher-Garwood point-resolved spectroscopy (MEGA-PRESS) sequence utilizing averaged free induction decay (FID) signals. Postprocessing and evaluation of spectra were performed with jMRUI and LCModel. 2HG concentration estimates, 2HG/Cr ratio, together with quality measures, including Cramér-Rao lower bounds (CRLBs), full-width at half-maximum (FWHM) values, and signal-to-noise ratio (SNR) were calculated using LCModel. Immunohistochemistry and genomic analysis results used as a ground truth were available for 15 patients. RESULTS: The threshold for test positivity was set according to the ROC curve at 1 mM. Calculated sensitivity was 57.14% (95% CI 0.20-0.88), specificity 87.5% (95% CI 0.46-0.99), positive predictive value 80%, and negative predictive value 70%. Overall diagnostic accuracy was 73.33% (95% CI 0.45-0.92). The 2HG/Cr ratio with the cutoff value 0.085 significantly improved sensitivity and overall diagnostic accuracy [85.71%, 95% CI 0.42-1.00 and 86.67%, (95% CI 0.60-0.98), respectively]. CONCLUSION: Multiple factors compromising spectral quality in the clinical adoption of edited 2HG MRS resulted in diminished sensitivity but clinically acceptable specificity. Furthermore, the 2HG/Cr ratio performs better than the sole 2HG concentration estimate in the pre-operative setting.

Assessment of the thymic morphometry using ultrasound in full-term newborns.

PURPOSE: The size of thymus is variable and depends on age of the individual. Thymus undergoes its maximum development at the time of birth, when it also has the greatest relative weight. The aim of our study was to compare the two ways of expressing the size of the newborns' thymus, the Thymus index and estimated volume of thymus. METHODS: The examined group consisted of 212 full-term newborns from Slovakia, Europe. We estimated the length, width and thickness of the left and right lobes. We used these data to calculate the approximate volume of the thymus. We also expressed size of the thymus as a multiple of the transverse diameter of the cranial part of the thymus and the sagittal area of the larger lobe of the thymus, the so-called Thymus index. Bilateral differences in thymus lobes' sizes, as well as the thymus' sizes between sexes and among the newborns of different types of birth were also analysed. RESULTS: Our results show that (1) the left thymus lobe is longer and thicker than the right lobe; (2) the Thymus index and the estimated volume of the thymus have a strong significant and positive correlation; (3) boys reach significantly higher values of the Thymus index than girls; and (4) when comparing the differences in the thymus size between the newborns born in two different ways (spontaneous and operatively), no significant difference was discovered. CONCLUSION: Ultrasound examination is safe, effective and suitable for simple assessment of the thymus size, which has a great variability in children. In other hand, the use of the Thymus index in everyday clinical practice is limited due to different mean values in a number of studies.

Congenital absence of the portal vein--Case report and a review of literature.

Congenital absence of the portal vein (CAPV) is a rare anomaly in which the intestinal and the splenic venous drainage bypass the liver and drain into systemic veins through various venous shunts. To our knowledge, we have reviewed all 83 cases of CAPV, since first described in 1793. This equates to a rate of almost 2.5 cases per year over the last 30 years. Morgan and Superina (1994, J. Pediatr. Surg. 29:1239-1241) proposed the following classification of portosystemic anomalies; either the liver is not perfused with portal blood because of a complete shunt (Type I) or the liver is perfused with portal blood due to the presence of a partial shunt (Type II). In our case, abdominal venous blood drained into the suprarenal inferior vena cava via the left renal vein and dilated left gastric veins. After analyzing all reported cases, we recognize that more than 65% of patients are females and more than 30% of all published cases had been diagnosed by the age of 5 years. Additional anomalies are common in CAPV. In the reported cases, more then 22% of patients had congenital heart disease. Other commonly found anomalies include abnormalities of the spleen, urinary and male genital tract, brain as well as skeletal anomalies. Hepatic changes such as focal nodular hyperplasia, hepatocellular carcinoma, and hepatoblastoma are diagnosed in more then 40% of patients. This article also illustrates the radiological findings of CAPV. Radiological evaluation by ultrasound, CT, and MRI is helpful to detect coexisting abnormalities.
