Insights

Adults with bicuspid aortic valve have excellent long-term survival but frequently experience cardiovascular events. Baseline aortic valve calcification and dysfunction predict these events.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Aortic Valve Disease

Background:

  • Bicuspid aortic valve is the most common congenital heart defect.
  • It is associated with valvular dysfunction, endocarditis, thoracic aorta dilatation, and dissection.

Purpose of the Study:

  • To assess the incidence of cardiac events in adults with bicuspid aortic valve.
  • To identify predictors of cardiac events in this population.

Main Methods:

  • Retrospective analysis of cardiac outcomes in ambulatory adults with bicuspid aortic valve.
  • Follow-up in a tertiary hospital center.
  • Kaplan-Meier curves and multivariate analysis were used.

Main Results:

  • 227 patients were followed for 13±9 years.
  • 38.8% experienced at least one cardiac outcome; 20-year incidence was 47±4%.
  • Baseline moderate-severe aortic valve dysfunction and calcification predicted composite endpoint.

Conclusions:

  • Long-term survival in bicuspid aortic valve patients is excellent.
  • Frequent cardiovascular events occur, with calcification and dysfunction as key predictors.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

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...

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

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...

Mitral Stenosis II: Clinical features and Diagnostic Tests

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...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...
