Aim      To study the right ventricular (RV) myocardial longitudinal systolic strain in patient with RV myocardial infarction (MI), and pulmonary embolism (PE) with and without McConnell’ phenomenon.Material and methods  This study included 53 patients with PE (mean age, 59.0±15.1 years; men, 58.5 %) and 30 patients with RVMI (mean age, 61.8±10.9 years; men, 90 %). Longitudinal strain of basal, medial and apical segments of the RV free wall (RVFW) and the interventricular septum (IVS) was determined in the mode of two-dimensional speckle tracking. Ratio of the IVS apical strain to the RVFW strain (apical ratio) was calculated. Systolic excursion of the RVFW apical segment (apical excursion) was measured in the anatomical M-mode from the apical four-chamber view.Results The McConnell’s sign was observed in 23 (43.4 %) of 53 patients with PE and in 16 (53.3 %) of 30 patients with RVMI (p>0.05). Irrespective of the cause for the RV damage, patients with the McConnell’s sign had higher values of the apical ratio (1.69±0.50 vs. 0.95±0.22; p<0.001; cutoff point, 1.18) and apical excursion (7.9±1.7 vs. 2.6±1.4 mm; p<0.001; cutoff point, 5.0 mm). Apical excursion closely correlated with the value of apical ratio (r=0.65; p<0.001) but not with the RVFW apical segment strain (r= –0.07; p>0.05).Conclusion      Incidence of the McConnell’s sign was similar in patients with PE and RVMI. McConnell’s sign is based on a passive systolic shift of the RVFW apical segment, which develops during contraction of the IVS apical segment. The greater the ratio of IVS apical segment to RBFW global strain the greater the amplitude of this shift. With the ratio value of 1.18 or more, the systolic shift of RVFW apical segment was >5 mm, which was visually perceived as the McConnell’s sign.

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.

We report a patient with cardiogenic shock (CS) in the course of acute right ventricular myocardial infarction (MI). Our case highlights the use of continuous veno-venous hemofiltration as a novel treatment option for acute kidney injury in the setting of CS and the use of rotational_atherectomy in patients with MI.
