Submitral aneurysm: An unusual localization of aneurysm complicating a myocardial infarction: A case report.

INTRODUCTION

and importance: Submitral aneurysms are an uncommon heart condition that is widespread among young black Africans, congenital etiology is the most common, when SMA is found in patients of other races, other etiologies must be sought, especially ischemic.

CASE PRESENTATION: We present the case of a 65-year-old male patient admitted for wide complex tachycardia at a rate of 198 bpm, in whom transthoracic echocardiography revealed a submitral aneurysm and coronary angiography revealed an occlusion of the left circumflex artery.

CLINICAL DISCUSSION: Submitral left ventricular aneurysm is a rare cardiac pathology with a variety of causes including inflammation, infection, traumatic illness, or, in rare cases, ischemic heart disease; it can be caused by a congenital defect in the posterior portion of the mitral annulus, which is more common in African population. Clinical manifestations are frequently serious and alarming, such as ventricular tachycardia, cardiogenic shock or an embolic phenomenon; however, asymptomatic cases are possible.

CONCLUSION

What we can retain from our case is that SMA can be the cause or consequence of coronary ischemia, so we must be vigilant in patients with an atypical clinical presentation.
