Summary
Practices for congenital aortic stenosis (AS) vary, especially for moderate cases. While mild and severe AS management shows consensus, definitions and treatments for moderate AS lack uniformity among pediatric cardiologists.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiovascular Surgery
Background:
- Congenital aortic valve stenosis (AS) management lacks standardized practice guidelines.
- Existing literature offers limited insight into current treatment approaches for AS.
Purpose of the Study:
- To investigate the uniformity and heterogeneity of current practices in managing congenital aortic stenosis (AS).
- To assess variations in follow-up, diagnostic methods, pharmacological therapy, and intervention strategies for AS.
Main Methods:
- A survey-based study distributed to academic pediatric cardiology programs in the US and internationally.
- Questionnaires evaluated follow-up schedules, diagnostic tests, medical treatments, exercise recommendations, and timing/type of therapeutic interventions.
Main Results:
- Consensus exists for managing mild and severe AS, but definitions and treatments for moderate AS vary significantly.
- Respondents showed disagreement on follow-up for moderate AS, while mild AS had annual follow-up recommendations and severe AS had varied intervention timings.
- Decision-making for biventricular vs. univentricular repair in neonates considered factors like mitral/aortic valve z-scores and left ventricle length, with varied use of Rhodes score.
Conclusions:
- Significant heterogeneity exists in the definition, evaluation, and treatment of moderate congenital aortic stenosis.
- While mild and severe AS management shows consensus, moderate AS requires further standardization.
- Current practices indicate a tendency towards catheter intervention for AS, with exceptions for specific valve conditions or regurgitation.

01:25Aortic 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...
01:26Mitral 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...
01:27Mitral Stenosis IV: Nursing Management
A comprehensive nursing assessment is essential for patients with valvular heart disease, which involves any dysfunction of the heart valves that could impact blood flow and overall heart function.Subjective Data Collection:Chief Complaint and Present Illness: Start with the patient's primary concerns, focusing on the onset, duration, and progression of cardiac symptoms such as dyspnea, fatigue, chest pain, and palpitations.Past Medical History: Collect detailed information on any previous...
01:17Aortic Regurgitation IV: Nursing Management
A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...
01:15Aortic 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...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
