Clinical Causes: Atherosclerosis (buildup of plaque in arteries) Trauma or injury to the chest Congenital vessel abnormalities Connective tissue disorders such as Marfan syndrome Infections leading to vessel wall weakening Previous coronary artery procedures or surgeries

Key Symptoms: Chest pain or discomfort, which may be sudden and severe Shortness of breath Palpitations or irregular heartbeat Lightheadedness or dizziness Fear or anxiety sensations often accompanying chest symptoms Signs of heart failure in advanced cases, like swelling in legs and shortness of breath on exertion

Diagnosis Path: Diagnosing coronary artery aneurysm and dissection involves a combination of clinical evaluation and imaging tests. Common diagnostic procedures include: - **Coronary angiography**: An invasive test where dye is injected into the coronary arteries to visualize any abnormal dilations or tears. - **Computed tomography angiography (CTA)**: A non-invasive imaging modality offering detailed images of coronary vessels. - **Magnetic resonance angiography (MRA)**: An alternative non-invasive scan useful in specific scenarios. - **Electrocardiogram (ECG)**: To detect signs suggestive of ischemia or infarction. - **Echocardiogram**: An ultrasound of the heart to assess overall heart function and look for complications. Accurate diagnosis is essential to determine the extent and specific nature of the vascular anomalies.

Treatment Protocols: Management strategies vary based on the size, location, and severity of the aneurysm or dissection. Treatment options may include: - **Medical therapy**: Using medications such as antiplatelet agents, beta-blockers, or statins to reduce the risk of clot formation and control blood pressure. - **Endovascular procedures**: Minimally invasive techniques like coil embolization or the placement of covered stents to seal aneurysms or repair dissections. - **Surgical intervention**: Procedures like coronary artery bypass grafting (CABG) or aneurysm resection may be necessary in complex cases or when the risks of complications are high. - **Monitoring**: Regular follow-up imaging to track changes in aneurysm size or the progression of dissection. The goal of treatment is to prevent complications such as rupture, heart attack, or sudden death, emphasizing the importance of personalized care plans.
