Insights

Stenting angioplasty is an effective treatment for pediatric coarctation of the aorta (COA). While generally safe, recurrent COA patients face higher risks of re-stenosis and hypertension post-procedure.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Interventional Cardiology

Background:

  • Optimal treatment timing and modality for pediatric coarctation of the aorta (COA) remain debated.
  • Surgery, balloon angioplasty, and stenting are effective for moderate to severe COA.
  • This study evaluates complications of COA stenting angioplasty in pediatric patients.

Purpose of the Study:

  • To investigate the complications associated with aortic stenting angioplasty in pediatric patients with coarctation of the aorta.
  • To compare outcomes between native and recurrent COA in pediatric patients undergoing stenting.

Main Methods:

  • Retrospective, descriptive study of pediatric patients (<20 years) undergoing aortic stenting for congenital COA.
  • Data collected from Rajaie Cardiovascular, Medical and Research Center between 2005-2010.
  • Analysis of early and late complications in native versus recurrent COA groups.

Main Results:

  • 26 pediatric patients (18 males, 9 females) with congenital COA underwent stenting.
  • 19 patients had native COA, 7 had recurrent COA.
  • Early complications were mostly minor; one major complication occurred. Late complications: 0% in native COA, 28.57% re-stenosis and 14.28% hypertension in recurrent COA.

Conclusions:

  • Endovascular stenting is an effective and safe treatment for pediatric native COA.
  • Patients with recurrent COA face higher risks of late complications like re-stenosis and hypertension after stenting.

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...

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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
Aortic Regurgitation III: Medical Management01:25

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...

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...
