Summary
Quadricuspid aortic valve (QAV), a rare congenital heart defect, was diagnosed in a pregnant patient. This case highlights the importance of monitoring for QAV during pregnancy due to potential risks.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Maternal-Fetal Medicine
Background:
- Quadricuspid aortic valve (QAV) is an extremely rare congenital heart anomaly, with limited documented cases.
- Pregnancy-associated QAV has not been previously reported in medical literature.
Observation:
- A 29-year-old pregnant patient presented with new-onset palpitations at 37 weeks gestation.
- Transthoracic echocardiography revealed a quadricuspid aortic valve (type b classification) with mild aortic regurgitation.
- The patient had no other congenital heart anomalies.
Findings:
- The patient successfully underwent a normal vaginal delivery without peripartum cardiac complications.
- This case represents the first reported instance of QAV identified during pregnancy.
Implications:
- QAV, though rare, can be associated with aortopathies, posing a high-risk state during pregnancy.
- Close cardiac monitoring is crucial for pregnant individuals with QAV, particularly in the second and third trimesters.
- Further research is needed to define the natural history and long-term outcomes of QAV, especially in pregnant populations.

337
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
175
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

492
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.

01:15Aortic Regurgitation I: Introduction
401
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

01:27Mitral Valve Prolapse I: Introduction
303
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
