Abstract null null Objective null To report the early postoperative outcomes in adults with tetralogy of Fallot (TOF) undergoing cardiac surgery and to identify patient factors associated with complications. null null null Patients and Methods null We performed a single-institution retrospective review of adults with TOF who underwent cardiac surgery from January 8, 2008, through June 21, 2018. Patients’ characteristics, preoperative imaging, surgical interventions, outcomes, and complications w...

The purpose of this study was to describe procedural outcomes, hemodynamic improvement, regression of left ventricular (LV) mass hypertrophy, and cardiovascular. The primary outcomes were procedural complications, reinterventions, and hemodynamic improvement after coarctation of aorta (COA) repair. The secondary outcomes were improvement in the severity of hypertension, regression of LV mass index, and incidence of cardiovascular events (atrial fibrillation, ventricular tachycardia, heart failur...

Abstract Background Pulmonary artery wedge pressure (PAWP) is often elevated in patients with right-sided congenital heart disease (CHD), raising the possibility of coexisting left heart disease, but pressure-volume relationships in the left and right sides of the heart influence one another through interdependence, which may be amplified in patients with CHD. Methods We hypothesized that increases in PAWP in CHD patients would be more strongly related to ventricular interdependence as compared ...

Abstract Background Previous studies have described echocardiographic indices of right ventricular (RV) diastolic function in patients with tetralogy of Fallot (TOF) but these indices have not been validated against invasive hemodynamic data. The purpose of this study was to determine echocardiographic predictors of severe RV diastolic dysfunction, and the impact of severe RV diastolic dysfunction on transplant-free survival. Methods Cohort study of TOF patients that underwent non-simultaneous c...

Ambulatory blood pressure monitoring (ABPM) is more sensitive than resting blood pressure (BP) assessment in detecting hypertension in patients with coarctation of aorta (COA). However, it is not known whether ABPM provides a better measure of left ventricular (LV) pressure load and LV remodeling

Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease with the majority of patients requiring additional surgical interventions in adulthood. We examined preoperative imaging in adult TOF patients to identify factors impacting early postoperative morbidity and

Adults with Ebstein anomaly (EA) have excellent mid and late outcomes following cone repair (CR); however, early morbidity and mortality are not well described. We examined the impact of perioperative comorbid conditions on early postoperative outcomes in adults with EA following CR. This is a

Abstract Background Inferior vena cava (IVC) size and collapsibility provides a noninvasive estimate of right heart filling pressures, an important determinant of right heart hemodynamic performance that is not measured by cardiac magnetic resonance imaging (CMRI). We hypothesized that compared to CMRI risk model alone, a combined CMRI-IVC risk model will have better correlation with disease severity and peak oxygen consumption (VO2) in patients with tetralogy of Fallot (TOF). Methods Retrospect...
