Classical Ozaki Procedure in a Seven-Month-Old Infant.

We present a case study of neotricuspidization of the aortic valve with neocusp suturing based on templates similar to those used in the Ozaki procedure but adapted for infants. This is an alternative for patients when valve reconstruction is impossible or risky. A good postoperative hemodynamic outcome was obtained, but it is necessary to evaluate this approach on the basis of long-term results.

Surgical Repair of Tetralogy of Fallot Using Autologous Right Atrial Appendage to Reconstruct the Right Ventricular Outflow Tract: A Case Series With Four-Year Follow-up.

This clinical case series describes the surgical management of tetralogy of Fallot in five children using autologous right atrial appendage to reconstruct the right ventricular outflow tract. Transthoracic echocardiography performed at four-year follow-up showed a mild residual gradient and moderate regurgitation of the neopulmonary valve in all cases.

Anomalous Left Coronary Artery from the Pulmonary Artery: How to Diagnose and Treat.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare coronary anomaly that can present in childhood or adulthood with a multitude of symptoms depending on the age of presentation. It should be suspected in infants presenting with heart failure in the setting of left ventricular systolic dysfunction and associated mitral regurgitation from papillary muscle ischemia. Adults with ALCAPA may present with cardiac ischemic symptoms.

Clinical Outcomes of Percutaneous Fontan Stenting in Adults.

Background: Fontan pathway stenosis is a well-known complication after palliation. Percutaneous stenting is effective for angiographic/hemodynamic relief of Fontan obstruction, but its clinical impact in adults remains unknown.

Methods: This was a retrospective cohort of 26 adults undergoing percutaneous stenting for Fontan obstruction from 2014 to 2022.

Transcatheter Treatment of Native Coarctation of the Aorta in a Child Using a Balloon-Expandable Endoprosthesis.

A 7-year-old child with native coarctation of the aorta was treated by transcatheter therapy using a 29-mm balloon-expandable stent. The procedure was successful and free of complications, and the patient was discharged home the same day. This stent has several features making it uniquely advantageous for treating this condition.

Optimizing Referral Timing of Patients With Fontan Circulatory Failure for Heart Transplant.

Background: There are no criteria guiding the timing of heart transplant referral for Fontan patients, nor are there any characteristics of those deferred or declined listing reported. This study examines comprehensive transplant evaluations for Fontan patients of all ages, listing decisions, and outcomes to inform referral practices.

Methods: Retrospective review of 63 Fontan patients formally assessed by the advanced heart failure service and presented at Mayo Clinic transplant selection committee meetings (TSM) January 2006 to April 2021.

How Does Cross-Sectional Imaging Impact the Management of Patients With Single Ventricle After Bidirectional Cavopulmonary Connection?

Background: There is currently no consensus regarding the use of surveillance cross-sectional imaging in pediatric patients after bidirectional cavopulmonary connection (BDCPC). We sought to determine how computed tomography with angiography (CTA) and cardiac magnetic resonance (CMR) imaging impacted the clinical management of pediatric patients after BDCPC.

Methods: A single-center retrospective study including patients with single ventricle who had BDCPC between 2010 and 2019, and CTA/CMR studies obtained in these patients, at ≤5 years of age, and with Glenn physiology.

Contemporary Early Postoperative Cone Repair Outcomes for Patients With Ebstein Anomaly.

Objective: To describe the early postoperative outcomes after cone repair (CR) for Ebstein anomaly (EA) across the age spectrum.

Patients And Methods: For this study, 284 patients from 1 to 73 years of age who underwent CR at Mayo Clinic from June 1, 2007, to December 21, 2018, were separated by age group (1-<4, 4-<19, 19-<40, and 40+ years) and by disease severity for analysis. Outcomes of interest included death, reoperation, readmission, early postoperative complications, cardiac intensive care unit and hospital length of stay, and need for superior cavopulmonary anastomosis.

Haemodynamic and prognostic associations of liver fibrosis scores in Fontan-associated liver disease.

Objectives: Fontan-associated liver disease (FALD) is universal post-Fontan palliation; however, its impact on survival remains controversial and current diagnostic tools have limitations. We aimed to assess the prognostic role of liver fibrosis scores (aminotransferase to platelet ratio [APRI] and fibrosis-4 [FIB-4]) and their association with haemodynamics and other markers of liver disease.

Methods: 159 adults (age ≥18 years) post-Fontan undergoing catheterisation at Mayo Clinic, Minnesota, between 1999 and 2017 were included.

Does the right ventricle size influence the left ventricle size and function in children with Ebstein anomaly?

Purpose: Patients with Ebstein anomaly (EA) have a variety of clinical manifestation. The assessment of structural and geometric characteristics of the heart is important for optimal management.

Methods: We retrospectively analyzed echocardiography database from 2009 to 2020.

Incidence of Reoperation After Surgical Procedure for Left Ventricular Outflow Tract Obstruction in Children and Young Adults.

Background: The common causes of subaortic left ventricular outflow tract obstruction (LVOTO) are hypertrophic cardiomyopathy (HCM) and membranous/tunnel subaortic stenosis (SAS). Reoperation after corrective surgery may be due to recurrent disease, associated congenital defects, or complications of the initial procedure. This study compares the late outcomes of young patients with HCM and SAS.

Fontan Palliation in Patients with Heterotaxy Syndrome: A Five Decade Experience.

Background: Patients with heterotaxy syndromes (right and left atrial isomerism) are at high risk of poor outcomes after single-ventricle palliation. However, the long-term outcomes and specific parameters associated with poor outcomes are incompletely understood.

Methods: A retrospective review was performed of all patients with atrial isomerism who had a Fontan at our institution from 1973 to 2020.

Outcomes of Biventricular and Single Ventricle Heterotaxy Patients: A Single Center Five-Decade Experience.

Background: Surgical palliation of patients with heterotaxy syndrome has proven challenging. Long-term outcomes have historically been poor. Factors contributing to these outcomes are not completely understood.

Surgical Management of a Giant Left Ventricular Fibroma in a Newborn.

This clinical case report describes surgical management of a giant left ventricular fibroma and postoperative venoarterial extracorporeal membrane oxygenation support in a newborn male. Transthoracic echocardiography performed at 9-month follow-up showed an ejection fraction of 33% and a cardiac index of 4.5 liters per minute per square meter.

Surgery for aortic recoarctation in children less than 10 years old: A single-center experience in Siberia, Russia.

Background: Persistence or recurrence of stenosis is a complication of initial coarctation repair. This study aims to report short-term outcomes of surgical management of recurrent coarctation and initial repair analysis.

Methods: We retrospectively reviewed our experience with 51 patients undergoing recoarctation surgical repair between 2008 and 2019 using antegrade cerebral perfusion (ACP) technique.

Systemic Semilunar Valve Repair/Replacement With Fontan Circulation: The Mayo Clinic Experience.

There is a paucity of literature regarding systemic semilunar valve (SSLV) dysfunction in patients with Fontan circulation. We sought to describe our center's 47-year experience with systemic semilunar valve replacement or repair (SSLVR) in patients with Fontan circulation. The Mayo Clinic Fontan Database is a comprehensive institutional database that stores clinical information of 1176 patients from 1973 to 2021.
