“…The study of the systolic function of the RV involves several parameters according to the new recommendations [4], no parameter alone could conclude the stage of the systolic dysfunction of the RV, some parameters are considered as little or not valid as the systolic ejection fraction according to the Simpson method, on the contrary the fraction of shortening of the RV, the analysis of the longitudinal function by the TAPSE or the peak of the S wave velocity in tissue Doppler are the most retained and validated parameters for the determination of the systolic function, it depends in fact on the underlying heart disease to be studied [5][6].…”

Introduction: Coronary heart disease is the main cause of morbidity and mortality worldwide. Right ventricular (RV) infarction is often difficult to diagnose and has a poor prognosis due to rhythmic and hemodynamic complications. Objective: The study of electrical, ultrasonographic, and coronarographic features of the VD Infarction. Materials and Methods: Retrospective study of patients hospitalized in the Cardiology Department of the Mohammed VI University Hospital in Marrakech over a period of 24 months for MDI extended to the RV. Results: 120 patients were hospitalized during this period for MI with extension to the VD. Atypical clinical presentation was noted in 10% of cases. Clinical examination on admission revealed signs of right heart failure in 18% of cases, including 6% complicated by cardiogenic shock. Thrombolysis was performed in 10% of the patients, 67% of them successfully. The ECG found an isolated extension to the V3R leads in 76% of the cases and in association with a V4R overshoot in 45% of the cases, conduction disorders were noted in 28% of the cases, presented essentially by first degree auriculoventricular block. Echocardiography showed impaired LV function in 82% of cases, and longitudinal systolic dysfunction of the LV in 65%. Coronary angiography was performed in 91% of the cases, half of which underwent coronary angioplasty. The combination of both CD and IVA damage was found in 40% of the cases, and damage to the middle DC was the most common in almost half of the cases. The most frequent complications were rhythmic and conductive disorders in 38% of cases, and the evolution was fatal in 8% of cases. Conclusion: Involvement of the RV during MI is characterized by a very critical initial phase, once overcome, the overall prognosis becomes favorable in the long term.

“…Although occasionally encountered in clinical practice, published cases of McConnell’s sign related to right ventricular ischemia are limited. 5 , 6 , 7 , 8 McConnell’s sign has long been established as an echocardiographic sign with high specificity for acute PE. 1 A recent meta-analysis in patients with suspected PE confirmed that McConnell’s sign had a sensitivity of 22% and a specificity of 97% for the detection of acute PE.…”
