Insights

Transcatheter closure of atrial septal defects (ASDs) can precipitate acute left ventricular failure in elderly patients. This case highlights a rare complication, emphasizing the need for careful patient selection and monitoring after ASD device closure.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Heart Failure Research

Background:

  • Congestive left ventricular failure is a known complication following surgical closure of atrial septal defects (ASDs), particularly in elderly individuals.
  • Transcatheter closure of ASDs is a common procedure, but potential complications require ongoing investigation.

Observation:

  • A 78-year-old woman with a history of an atrial septal defect (ASD) and preserved left ventricular function underwent successful transcatheter closure using an Amplatzer Septal Occluder.
  • Two hours post-procedure, the patient developed acute pulmonary edema and left ventricular failure, characterized by a significant increase in end-diastolic diameter and a drop in ejection fraction.

Findings:

  • The patient required mechanical ventilation and inotropic support for several days due to severe left ventricular failure.
  • Diuretic therapy was administered until ejection fraction improved, and the patient was hospitalized for two weeks post-intervention.
  • This represents a novel case of left ventricular failure occurring after transcatheter ASD closure.

Implications:

  • Reduced preload over decades may contribute to impaired ventricular compliance, predisposing elderly patients to acute left ventricular failure after ASD closure.
  • This case underscores the importance of considering ventricular compliance and potential hemodynamic shifts in elderly patients undergoing atrial septal defect closure.
  • Further research is warranted to identify risk factors and optimize management strategies for preventing left ventricular failure post-ASD closure.

Mitral Stenosis I: Introduction01:22

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...

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...

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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Aneurysm 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...
