An analysis of the publication of the outstanding Russian therapist and cardiologist D.D. Pletnev (18711941) is given in the article. In 1925, he published an article On the issue of lifetime differential diagnosis of right and left coronary artery thrombosis in the journal Russian Clinics in Russian and German languages. Timely diagnosis of right myocardial infarction determines the prognosis and treatment tactics of this disease, and the case itself has a priority for the Russian science. The authors emphasize the outstanding talent of D.D. Pletnev as a physician and scientist, whose name is associated with the emergence of one of the most brilliant therapeutic schools (A.L. Myasnikov, E.I. Chazov, etc.).

Abstract Background Isolated right ventricular myocardial infarction (RVMI) due to a recessive right coronary artery (RCA) occlusion is a rare presentation. It is typically caused by right ventricle (RV) branch occlusion complicating percutaneous coronary intervention. We report a case of an isolated RVMI due to flush RCA occlusion presenting via our primary percutaneous coronary intervention ST-elevation myocardial infarction pathway. Case summary A 61-year-old female smoker with a history of hypercholesterolaemia presented via the primary percutaneous coronary intervention pathway with sudden onset of shortness of breath, dizziness, and chest pain while walking. Transradial coronary angiography revealed a normal left main coronary artery, large left anterior descending artery that wrapped around the apex and dominant left circumflex artery with the non-obstructive disease. The RCA was not selectively entered despite multiple attempts. The left ventriculogram showed normal left ventricle (LV) systolic function. She was in cardiogenic shock with a persistent ectopic atrial rhythm with retrograde p-waves and stabilized with intravenous dobutamine thus avoiding the need for a transcutaneous venous pacing system. A computed tomography pulmonary angiogram demonstrated no evidence of pulmonary embolism while an urgent cardiac gated computed tomography revealed a recessive RCA with ostial occlusive lesion. A cardiac magnetic resonance imaging confirmed RV free wall infarction. She was managed conservatively and discharged to her local district general hospital after 5th day of hospitalization at the tertiary centre. Discussion This case describes a relatively rare myocardial infarction presentation that can present with many disease mimics which can require as in this case, a multi-modality imaging approach to establish the diagnosis.

Perinatal myocardial infarction caused by aortic root and coronary artery thrombosis in neonatal period is extremely rare and has a gloomy prognosis that may cause devastating complications. A 3-h newborn baby who had acute myocardial infarction findings on postnatal electrocardiography had a thrombus in the aortic root with hyperechogenic right coronary artery region, and impaired right ventricular functions on echocardiography. The patient was urgently operated and thrombus was successfully removed from the aortic root and the right coronary artery. In conclusion, for large thrombi posing a risk for embolization in the aortic root, an urgent surgical thrombectomy procedure should be performed.

Myocardial infarction (MI) (i.e., heart attack) is the irreversible death (necrosis) of heart muscle secondary to prolonged lack of oxygen supply (ischemia) which accounts for a large number of deaths in the hospital. Diagnosis of myocardial infarction is confirmed based on clinical manifestations and electrocardiographic changes along with increased cardiac enzymes. Electrocardiogram (ECG) is one of the safest and easiest methods in the first place. Therefore, this study aimed to investigate the diagnostic value of standard electrocardiogram in the diagnosis of acute right ventricular infarction following lower cardiac infarction. This research was carried out at a time interval of one and a half years to diagnose acute primary infarction. In this method, the diagnostic value of ST↓ in lead I, ST↓ in lead aVL and I ST↓ + aVL, compared with ST↑ in lead V4R was investigated for diagnosis of right ventricular infarction. ST↑ in the lead V4R is a gold standard for the detection of right ventricular MI. All the patients who had the inclusion criteria were allowed to participate in the study. A total of 66 patients participated in the study. Accordingly, 58 (87%) were male and 8 (13%) were female. The mean age of the population was 54.9 ± 11.41. According to the ST↑ standard in lead V4R, 26 patients (39%) had right ventricular myocardial infarction. There was no significant relationship between angina pectoris and premature infarction (P-Value = 0.869). In this study, the right ventricular was most commonly involved in right coronary artery (78%). There was no significant relationship between the occlusion of right coronary artery and right ventricular infarction in 60 patients (P-Value = 0.94). The results showed that electrocardiogram manifestations help determine the occlusion site and the area at risk (ST↓ in lead aVL and aVL + I, sensitivity = 96%). In myocardial infarction, symptoms such as the ST-Segment elevation in lead aVR and ST-Segment depression in the lower leads are possible. Accordingly, in the lower infarction, ST changes in the leads V1-V6 are helpful in detecting patients at risk. Thus, the use of electrocardiogram in acute myocardial infarction helps detect more invasive patients and prevents extensive myocardial damage and other complications.
