Objectives: The objectives of this study were to evaluate the prevalence of the right ventricular infarction and its diagnostic, therapeutic and prognostic characteristics. Patients and methods:A single center retrospective study was carried out between January 2011 and December 2014. Patients who were diagnosed with right ventricular infarction at electrocardiogram and echocardiography were recruited.Outcomes: Among the 159 patients hospitalized for myocardial infarction, 10 had myocardial infarction extended to the right ventricle (6.3%). It occurred on an inferior infarction in 7 cases out of 35 and anterior infarction in 3 cases out of 124. The mean age was 53 years and sex ratio M/F of 2.33. All patients had at least 3 cardiovascular risk factors. Right-sided heart failure was found in 4 patients. Right ventricular infaction was associated with inferior STEMI in 7 patients, and anterior STEMI in 3 patients. Echocardiography showed right ventricular dilatation and impaired right ventricular systolic function in respectively 6 cases. Thrombolysis was performed in 7 patients and rescue angioplasty in 1 case. A regressive cardiogenic collapse was noted in 6 cases and one death in 1 case. Conclusion:Right ventricular infarction is relatively rare and usually related to an extension of an inferior myocardial infarction. Hemodynamic instability is of worse prognosis.

Introduction: Left atrial myxoma is a rare benign tumor. It can be an embolic complication such as an ischemic stroke. Case presentation: It was a 48 years old patient who was referred to our unity for the etiological investigation of an ischemic stroke. She did not have personal medical and surgical history. She had a recent right hemiplegia. The cardiac auscultation found a mitral diastolic murmur. The brain CT showed a recent ischemic stroke in the superficial and deep left sylvian territory. The transthoracic echography revealed a myxomatous mass, responsible of an obstacle of the left ventricular filling. Anticoagulation by antivitamin K (AVK) had been initiated and a resection of the mass indicated. Conclusions: The left atrial myxoma is a rare benign tumor whose mode of revelation can be an embolic complication. The Echocardiography is reference imaging modality in diagnosis with a high sensitivity.

Introduction: Sudden cardiac death (SCD) remains a major public health issue. In Senegal, there is a lack of data on this phenomenon; this underlies the relevance of this study whose objective is to study the epidemiological profile of victims experiencing unrecovered sudden cardiac arrest at Aristide LE DANTEC Hospital. Patients and Methods: This is a transverse study with retrospective data collection from January 1, 2016 to January 31, 2017. Included, in the study were all victims of sudden cardiac death in Dakar who had a necropsy in the morgues of Aristide Le Dantec Hospital. Results: We recorded 69 cases of sudden death of cardiovascular origin from 169 forensic autopsy reports, or 40.8% of autopsies. The average age was 44 years with a male predominance in 76.81%. The large majority of death occurred at home (26%), without witnesses (48%) and at rest (36%). Two cases of sudden death, or 3%, occurred at exertion. These deaths were recorded in 16% of cases in the middle of the day. The highest death rate was recorded during the month of December (15.9%). Malaise was the predominant symptom (13%) followed by emotional stress (6%). The existence of a history could only be clarified in 4% of cases. The electrocardiogram was only performed in 1 case. At necropsy, ischemic heart disease was the leading disease (46%), 26% of which was due to myocardial infarction, followed by hypertrophic cardiomyopathy (16%) and mixed cardiomyopathy (13%). Tamponade, dilated cardiomyopathy and aortic dissection were found in 9%, 6% and 4% of cases, respectively. Conclusion: Sudden cardiac death is a major public health problem. In the Senegalese population, victims of unrecovered SCD are relatively young with a predominance of men. Coronary artery disease is the most frequently implicated pathology. Faced with this observation, a national program for the integrated control of cardiovascular risk factors is necessary.
