Summary
Bone dysmorphogenesis and Marfanoid habitus are predictors of sclerodegenerative aortic valve lesions (SDAVL). Three or more bone dysmorphogenesis signs indicate increased risk for SDAVL development.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Rheumatology
Background:
- Sclerodegenerative lesions and calcific stenosis of the aortic valve (AV) are significant health concerns.
- The role of dysplastic syndromes and phenotypes in AV disease development requires further investigation.
Purpose of the Study:
- To estimate the role of different dysplastic syndromes and phenotypes in the development of sclerodegenerative lesions and calcific stenosis of the aortic valve (AV).
Main Methods:
- Examined 150 patients (89 with sclerodegenerative AV lesions (SDAVL), 61 controls).
- Included patients aged 42-83 years.
- Histological examination of 25 valves from patients with critical calcific aortic stenosis (CAS).
Main Results:
- Marfanoid habitus (18%) and mitral valve prolapse (10.7%) were common in older age groups.
- An association was found between bone signs of dysmorphogenesis and the development of SDAVL and CAS.
Conclusions:
- Three or more signs of bone dysmorphogenesis, along with Marfanoid habitus, should be considered a predictor of SDAVL.
- These findings highlight the link between connective tissue disorders and aortic valve disease.

Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
Mitral Stenosis I: Introduction
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...
Mitral Valve Prolapse I: Introduction
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...
Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
Cardiomyopathy IV: Restrictive Cardiomyopathy
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
Aortic Regurgitation I: Introduction
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...
