AIMS: The Fontan operation is associated with significant long-term morbidity and mortality, posing challenges in management. No haemodynamic classification has been established to aid management and prognostication of patients with Fontan palliation. Our aim was to assess haemodynamic profiles for Fontan patients and evaluate their relationships to prognosis. METHODS AND RESULTS: Eighty-four adult Fontan patients without obstruction or significant valve disease undergoing cardiac catheterizatio...

Background National prevalence and outcomes of Fontan operation in the USA is unknown. Study objective was to determine trends (temporal change) in the annual volume of Fontan operations, in-hospital mortality, postoperative complications and type of hospital discharge. Methods Review of the Nationwide Inpatient Sample for patients that underwent Fontan operation from 2001 to 2014 using the International Classification of Diseases-Ninth Revision, Clinical Modification procedure code for Fontan o...

OBJECTIVE: To review our experience with balloon testing prior to atrial septal defect (ASD) closure in adults with left ventricular (LV) diastolic dysfunction. BACKGROUND: ASD closure in patients with LV diastolic dysfunction may precipitate LV failure. Temporary ASD occlusion has been used in this scenario but data are limited. METHODS: Retrospective review of 27 patients age ≥ 50 years undergoing temporary ASD balloon occlusion between 2000 and 2018 for suspected LV diastolic dysfunction or e...

BACKGROUND: We hypothesized that echocardiographic indices of right ventricular to pulmonary artery (RV-PA) coupling were comparable to cardiac magnetic resonance imaging (CMRI)-derived RV volumetric indices in predicting disease severity in chronic pulmonary regurgitation (PR). METHODS: Patients with ≥ moderate PR (2003-2015) with and without prior CMRI scans were enrolled into the study cohort and validation cohort, respectively. Endpoint was to determine the association between noninvasive RV...

Background Tachyarrhythmias and bradyarrhythmias affect 20%–50% of adult patients with tetralogy of Fallot (TOF) and some of these patients will require cardiac implantable electronic devices (CIED) such as pacemaker and/or internal cardioverter defibrillator. Methods The Mayo Adult Congenital Heart Disease database was queried for patients with repaired TOF and history of CIED implantation, 1990–2017. The study objectives were: (1) determine the occurrence of device-related complications define...

The performance of the modified Bernoulli equation to estimate the RV-RA pressure gradient by continuous wave Doppler in severe tricuspid regurgitation (TR) is not known. Simultaneous continuous wave (CW) Doppler of the TR jet was prospectively obtained at time of cardiac catheterization in seven

Left ventricular noncompaction (LVNC) is an inherited cardiomyopathy characterized by prominent left ventricular trabeculations and deep intertrabecular recesses. LVNC is associated with an increased risk of arrhythmia, embolic events, and heart failure. There is limited information regarding

The natural history of moderate aortic stenosis (mod AS) requires clarification to provide optimal management strategy. Patients with aortic valve area > 1 and ≤1.5cm2 in 2012 were identified and stratified by stroke volume index (SVI) and left ventricular ejection fraction (LVEF). All-cause
