Background: COVID-19 is a great medical challenge as it provokes acute respiratory distress and has pulmonary manifestations and cardiovascular (CV) consequences., Aims: This study compared cardiac injury in COVID-19 myocarditis patients with non-COVID-19 myocarditis patients., Methods: Patients who recovered from COVID-19 were scheduled for cardiovascular magnetic resonance (CMR) owing to clinical myocarditis suspicion. The retrospective non-COVID-19 myocarditis (2018-2019) group was enrolled (n = 221 patients). All patients underwent contrast-enhanced CMR, the conventional myocarditis protocol, and late gadolinium enhancement (LGE). The COVID study group included 552 patients at a mean (standard deviation [SD]) age of 45.9 (12.6) years., Results: CMR assessment confirmed myocarditis-like LGE in 46% of the cases (68.5% of the segments with LGE <25% transmural extent), left ventricular (LV) dilatation in 10%, and systolic dysfunction in 16% of cases. The COVID-19 myocarditis group showed a smaller median (interquartile range [IQR]) LV LGE (4.4% [2.9%-8.1%] vs. 5.9% [4.4%-11.8%]; P <0.001), lower LV end-diastolic volume (144.6 [125.5-178] ml vs. 162.8 [136.6-194] ml; P <0.001), limited functional consequence (left ventricular ejection fraction, 59% [54.1%-65%] vs. 58% [52%-63%]; P = 0.01), and a higher rate of pericarditis (13.6% vs. 6%; P = 0.03) compared to non-COVID-19 myocarditis. The COVID-19-induced injury was more frequent in septal segments (2, 3, 14), and non-COVID-19 myocarditis showed higher affinity to lateral wall segments (P <0.01). Neither obesity nor age was associated with LV injury or remodeling in subjects with COVID-19 myocarditis., Conclusions: COVID-19-induced myocarditis is associated with minor LV injury with a significantly more frequent septal pattern and a higher pericarditis rate than non-COVID-19 myocarditis.

Multislice computed tomography is an imaging method of internal organs including heart and vessels with the use of X-ray. The indications for computed tomography of the heart include also congenital heart diseases and the evaluation of the great arteries. Ultrasonography is a method of choice in heart evaluation. The authors show the possibilities of modern multislice computed tomography in congenital heart diseases imaging based on their own material.

Transcatheter implantation of pulmonary valve became a big step forward in the field of interventional cardiology. It is especially important in the patients with defects of the right ventricular outlet tract, because they were usually candidates for multiple surgical operations. We present first transcatheter replacement of pulmonary valve in 23-years-old man. The 'Melody' valve was implanted successfully. There were no complications and the patient was discharged in good condition.
