Insights
A rare congenital heart anomaly, single coronary artery, was diagnosed in a young male presenting with chest pain. Imaging revealed one artery originating from the right sinus, branching to supply both right and left heart areas.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Medical Imaging
Background:
- Congenital coronary artery anomalies are rare but can cause significant cardiovascular events.
- Single coronary artery (SCA) is a rare anomaly where only one coronary artery arises from the aorta.
- SCA can present with diverse clinical manifestations, including chest pain, myocardial infarction, and arrhythmias.
Purpose of the Study:
- To report a case of single coronary artery presenting with chest pain in a young male.
- To highlight the diagnostic utility of coronary angiography and computed tomography coronary angiography in identifying this anomaly.
Main Methods:
- A young male patient presented with acute chest pain.
- Diagnostic workup included coronary angiography and computed tomography coronary angiography.
- Imaging findings were analyzed to characterize the coronary artery anatomy.
Main Results:
- Coronary angiography and computed tomography coronary angiography revealed a single coronary artery originating from the right coronary sinus.
- This single coronary artery bifurcated into branches supplying both the right and left coronary territories.
- The anomaly was identified as a single coronary artery originating from the right sinus of Valsalva.
Conclusions:
- Single coronary artery is a rare congenital anomaly that can mimic ischemic heart disease.
- Advanced imaging modalities like computed tomography coronary angiography are crucial for accurate diagnosis.
- Early diagnosis and management are essential to prevent adverse cardiovascular outcomes in patients with SCA.
Abstract:
A young male presented to the hospital with chest pain. A coronary angiogram and a subsequent computed tomography coronary angiogram revealed a single coronary artery arising from the right coronary sinus which bifurcated into the right coronary artery and a large branch which supplies the left coronary artery territory. (Level of Difficulty: Beginner.).

01:30Coronary Artery Disease III: Clinical Manifestations
91
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

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...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

62
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

01:21Coronary Circulation
5.1K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

180
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
