|July 28, 2021
Summary
Physical examination revealed a rare congenital heart condition, an accessory left ventricle, misdiagnosed initially as a ventricular septal defect. This case highlights the importance of physical exam findings in diagnosing uncommon cardiac anomalies.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Diagnostic Imaging
Background:
- Physical examination skills are crucial in cardiology.
- Misdiagnosis can occur when imaging findings conflict with clinical examination.
- Congenital cardiac anomalies require accurate and timely diagnosis.
Purpose of the Study:
- To report a case of accessory left ventricle.
- To emphasize the role of physical examination in diagnosing rare cardiac conditions.
- To highlight discordance between imaging and physical exam findings.
Main Methods:
- Case report presentation.
- Review of patient's clinical presentation and diagnostic workup.
- Comparison of physical examination findings with imaging results.
Main Results:
- A patient initially diagnosed with ventricular septal defect was found to have an accessory left ventricle.
- Discordance between physical examination and imaging led to the correct diagnosis.
- Accessory left ventricle is a rare, benign congenital cardiac condition.
Conclusions:
- Physical examination remains a vital tool in diagnosing congenital cardiac conditions.
- Careful correlation of clinical findings with imaging is essential.
- Rare cardiac anomalies may be overlooked without thorough physical assessment.

Chambers of the Heart
7.3K
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Mitral Stenosis I: Introduction
93
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Development of the Heart
1.5K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Cardiovascular System Abnormal Findings II: Auscultation
310
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.

Aortic Regurgitation I: Introduction
92
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...

Mitral Regurgitation I: Introduction
105
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
