Insights
Myocardial bridging (MB) is a congenital heart defect where a coronary artery segment runs within the heart muscle. This case study shows successful management of MB causing ischemia with calcium channel blockers.
Area of Science:
- Cardiology
- Congenital Heart Anomalies
Background:
- Myocardial bridge (MB) is a congenital coronary anomaly where a segment of a coronary artery tunnels through the heart muscle.
- This anomaly can lead to myocardial ischemia, particularly during increased heart rate or stress.
Observation:
- A 44-year-old man presented with chest pain and dizziness, exacerbated by a common cold.
- Coronary angiography revealed a myocardial bridge in the mid-left anterior descending artery (LAD).
- The LAD segment showed significant stenosis, indicative of ischemia.
Findings:
- The patient was treated with a calcium channel blocker as initial therapy.
- The pharmacological approach effectively managed the symptoms associated with the myocardial bridge.
- The patient remained asymptomatic during a two-year follow-up period.
Implications:
- This case highlights the potential for non-surgical management of symptomatic myocardial bridges.
- Calcium channel blockers may be a viable first-line treatment for myocardial bridging causing ischemia.
- Further research into conservative management strategies for MB is warranted.
Abstract:
Myocardial bridge (MB) is a congenital coronary anomaly in which a portion of the coronary artery courses intramyocardium instead of the normal trajectory on the epicardial surface. We report a case study with a 44-year-old man from Faryab Province in Afghanistan who presented chest pain and dizziness while suffering a common cold. After full investigation, the patient underwent coronary angiography which showed a myocardial bridge at the middle portion of the left anterior descending artery (LAD) with a significant stenosis causing ischemia. We treated the patient with a calcium channel blocker as initial treatment. The patient tolerated the medication well and remained asymptomatic during two years follow-up.
