Mitral Stenosis III: Medical Management01:26

Mitral Stenosis III: Medical Management

20
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...

Overview of Systemic Arteries

1.0K
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

324
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

34
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...

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Interventional Cardiology

Background:

  • Hybrid palliation, combining ductal stenting and pulmonary artery banding, is a standard Stage I palliative surgery for ductal-dependent systemic circulation.
  • Off-label stent use is common in this procedure, with limited data on specific devices like the Valeo stent.

Purpose of the Study:

  • To describe the experience and outcomes of using the balloon-expandable Valeo stent for ductal stenting in ductal-dependent systemic circulation.
  • To assess procedural success, survival rates, complications, and re-intervention rates associated with Valeo stent use.

Main Methods:

  • A retrospective analysis of 17 patients who underwent hybrid procedures with ductus arteriosus stenting and pulmonary artery banding between November 2019 and September 2024.
  • Descriptive statistics were used to analyze procedural data, patient demographics, and outcomes.

Main Results:

  • Seventeen patients (median age 14 days, median weight 3.47 kg) received Valeo stents. Fifteen had a single stent, two required an additional stent.
  • No intraoperative deaths occurred; one in-hospital death was recorded. Interstage mortality was 30% (5/17 survived to subsequent procedure).
  • The re-intervention rate was 35% (6/17), including additional stenting for ductal constriction and balloon angioplasty for growth. No in-stent stenosis or migration was observed.

Conclusions:

  • The Valeo stent is a suitable and effective option for ductal stenting in hybrid procedures for neonates with hypoplastic left heart syndrome and other left heart obstructive lesions.
  • The stent demonstrates a good safety profile and effectively maintains ductal patency with a low rate of interstage in-stent stenosis.
