Summary
Myocardial bridging, a congenital anomaly where coronary arteries run through heart muscle, can cause heart failure symptoms. This case highlights its under-recognized potential for severe ventricular dysfunction and reduced cardiac output.
Area of Science:
- Cardiology
- Congenital Heart Disease
Background:
- Myocardial bridging is a congenital anomaly where a segment of an epicardial coronary artery courses through the myocardium.
- It is an under-recognized cause of angina pectoris.
Observation:
- This case report details a rare presentation of myocardial bridging manifesting as heart failure symptoms.
- The condition resulted in significant ventricular dysfunction and a marked decrease in cardiac output (CO).
Findings:
- The patient experienced severe exertional dyspnea and functional limitations due to the myocardial bridging.
- Standard ischemic workup, including diagnostic imaging and angiograms, did not fully explain the symptom severity.
Implications:
- Hemodynamic studies and cardiopulmonary exercise testing were crucial in revealing the extent of the patient's condition.
- This case underscores the importance of considering myocardial bridging in unexplained heart failure and the utility of advanced functional testing.

01:26Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

01:17Pathophysiology of Heart Failure
1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

01:22Heart Failure Drugs: β-Blockers
337
β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...
