Insights

Fontan surgery outcomes were analyzed in Asian patients. Heterotaxy syndrome and high pulmonary artery pressure were poor prognostic factors, while low pulmonary artery pressure and less atrioventricular valve regurgitation improved survival.

Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Disease Surgery
  • Outcomes Research

Background:

  • Limited data exists on Fontan surgery outcomes in Asian populations.
  • This study addresses the need for regional data from the Republic of Korea.

Purpose of the Study:

  • To analyze the outcomes of Fontan surgery in a large cohort of Korean patients.
  • To identify risk factors for early and late mortality after Fontan surgery in this population.

Main Methods:

  • Retrospective review of medical records from 1,732 patients who underwent Fontan surgery across 10 cardiac centers.
  • Data collected included patient demographics, surgical type, pre-operative conditions, and survival rates.

Main Results:

  • Overall survival rates at 10, 20, and 30 years were 91.7%, 87.1%, and 74.4%, respectively.
  • Risk factors for early mortality included male sex, heterotaxy syndrome, atriopulmonary (AP) type surgery, and high pre-operative mean pulmonary artery pressure (mPAP).
  • Risk factors for late mortality included heterotaxy syndrome, genetic disorders, significant atrioventricular valve regurgitation (AVVR), high pre-operative mPAP, and absence of fenestration.

Conclusions:

  • Heterotaxy syndrome is a significant poor prognostic factor in Asian patients undergoing Fontan surgery.
  • Preoperative low mPAP and less AVVR are associated with improved early and long-term outcomes.

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
