This case highlights the diagnostic challenge of Type A aortic dissection masquerading as acute myocardial infarction and underscores the importance of considering aortic dissection in patients with new-onset aortic regurgitation murmurs.
Type A aortic dissection (TAAD) is a life-threatening condition that often presents diagnostic challenges, particularly when mimicking acute myocardial infarction (AMI). This case report describes a 31-year-old male with a history of fever and no cardiovascular history who presented with acute chest pain and rapidly developed hemodynamic instability. Initial assessments revealed mild aortic regurgitation (AR) and ascending aortic dilation but no aortic dissection was reported. ECG showed ST-segment changes, yet coronary angiography ruled out obstructive coronary disease. Serial daily echocardiograms demonstrated rapid progression of AR from mild to severe within 72 h, accompanied by worsening left ventricular dysfunction. Reassessment of aortic CT confirmed TAAD with left main coronary artery involvement. Different elements of his presentation suggested possible other diagnoses, including TAAD, AMI and myocarditis. We discuss how evaluating these other diagnostic possibilities led to the correct diagnosis. This case underscores the diagnostic pitfalls of TAAD masquerading as AMI, it demonstrates the need to consider aortic dissection in patients with AMI and/or emerging diastolic murmurs of AR.
Wei et al. (Fri,) conducted a case report in Type A Aortic Dissection (n=1). surgical repair of aorta, aortic valve repair, and coronary ostial reconstruction was evaluated on Acute Myocardial Injury in the context of Aortic Dissection. Surgical intervention for Type A aortic dissection successfully led to recovery of left ventricular function after severe aortic regurgitation and myocardial injury.
