Summary
Patients with d-transposition of the great arteries after a Mustard procedure face a risk of coronary embolism and myocardial infarction. A mural thrombus in the systemic ventricle was identified as a likely cause in this case report.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- D-transposition of the great arteries (dTGA) is a complex congenital heart defect.
- The Mustard procedure is a palliative surgical intervention for dTGA.
- Long-term complications following palliative cardiac surgery require ongoing investigation.
Observation:
- A young male patient with a history of Mustard procedure for dTGA presented with recurrent myocardial infarctions.
- Cardiac imaging revealed a mural thrombus within the systemic ventricle.
- Coronary embolism was identified as the etiology for the myocardial infarctions.
Findings:
- The mural thrombus served as a probable nidus for coronary embolism.
- Patients undergoing the Mustard procedure are identified as a population at risk for coronary embolization.
- Coronary embolism can manifest as myocardial infarction in the late post-operative period.
Implications:
- This case highlights a significant, potentially life-threatening complication in Mustard procedure survivors.
- Awareness of coronary embolism risk is crucial for the long-term management of dTGA patients.
- Timely diagnosis and management of embolic events may prevent adverse outcomes, including sudden cardiac death.

01:21Myocarditis I: Introduction
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
01:27Myocarditis II: Clinical Features and Diagnostic Tests
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
01:14Myocarditis III: Medical Management
Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...
01:30Acute Coronary Syndrome III: Diagnostic Studies
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
