REVIEW
Matthew I Jones, Shakeel A Qureshi
Surgical repair of tetralogy of Fallot (ToF) in childhood is associated with generally good outcomes, and almost all children can be expected to survive until adulthood. However, significant pulmonary regurgitation leading to progressive right ventricular dilatation is common in teenagers or young adults because of the nature of the surgical intervention. In patients whose repair included placement of a right ventricle to pulmonary artery conduit, it has been possible to place a stented valve within the conduit to treat this...

BACKGROUND: Late after tetralogy of Fallot (TOF) repair some patients exhibit aortic dilatation and stiffness. Noninvasive assessment of aortic stiffness could contribute to understand this aortopathy and may be important in risk stratification for major aortic event. METHODS: We included prospectively 82 adults after TOF repair and 41 age- and sex-matched normal controls. Aortic diameters were measured by two-dimensional transthoracic echocardiography and the aortic z-score was estimated...

BACKGROUND: We set out to determine whether patients with tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries (TOF/PA/MAPCA) are at risk for elevated dead space ventilation fraction (VD/VT), and whether this is associated with prolonged mechanical ventilation. We hypothesized that elevated VD/VT (>20%) in the first 24 hours after unifocalization surgery is associated with increased risk for prolonged mechanical ventilation (>7 days). METHODS: All patients with TOF/PA/MAPCA undergoing unifocalization surgery between January 2003 and December 2015 were included in this study...

BACKGROUND: Cardiac disease is associated with adverse outcomes in pregnancy and is the leading cause of indirect maternal death in the United Kingdom (UK) and internationally. National and international guidelines recommend women should receive care from multidisciplinary teams; however evidence is lacking to inform how they should be operationalised. OBJECTIVES: To describe the composition and processes of multidisciplinary care between maternity and cardiac services before, during and after pregnancy for women with cardiac disease, and explore clinicians' (cardiologists, obstetricians, nurses, midwives) and women's experiences of delivering/receiving care within these models...

Candida prosthetic endocarditis (CPE) is an uncommon and fatal complication in adults with congenital heart disease. The current guidelines for the management of fungal endocarditis recommend a combination of surgical and medical therapy. However, it still remains uncertain when surgical management in CPE patients should be performed. Therefore, the prognosis of CPE patients is very poor. Here we report a case of CPE in a 31-year-old woman who had undergone surgical repair for tetralogy of Fallot during childhood and pulmonary valve replacement at the age of 21 years...

Tetralogy of Fallot (TOF) often carries long-term seqüelae following surgical intervention. We hypothesized that early perioperative factors are associated with long-term adverse right ventricular (RV) remodeling, diminished exercise capacity, and increased morbidity. We conducted a retrospective cohort study of patients operated for TOF that underwent cardiac magnetic resonance imaging study (CMR), exercise stress test (EST), and detailed review of past medical history. Outcome variables included measures of RV size, and function, maximal work rate, and oxygen consumption, and interim hospitalizations, surgeries, and catheterizations...

Progressive aortic root dilation and stiffening have been reported in patients with tetralogy of Fallot (TOF), even after repair. However, the implications of such aortic dilation and stiffening have not been fully assessed. A stiff aorta has a negative effect on the coronary circulation. 15 patients with TOF after repair were enrolled in this study. Using a left ventriculogram and pressure waveform recorded by a pressure sensor-mounted catheter, we analyzed the diameter and distensibility of the ascending and descending aorta...

BACKGROUND: Junctional ectopic tachycardia is a serious arrhythmia that frequently occurs after tetralogy of Fallot repair. Arrhythmia prophylaxis is not feasible for all pediatric cardiac surgery patients and identification of high risk patients is required. The objectives of this study were to characterize patients with JET, identify its predictors and subsequent complications and the effect of various treatment strategies on the outcomes in selected TOF patients undergoing total repair before 2 years of age...

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect. Early surgical repair has dramatically improved the outcome of this condition. However, despite the success of contemporary approaches with early complete repair, these are far from being curative and late complications are frequent. The most common complication is right ventricle outflow tract (RVOT) dysfunction, affecting most patients in the form of pulmonary regurgitation, pulmonary stenosis, or both, and can lead to development of symptoms of exercise intolerance, arrhythmias, and sudden cardiac death...

Ultrasound-guided central venous cannulation is now considered as the standard of care, and this has largely replaced blind central venous cannulation using anatomical landmarks. We are reporting a case of inadvertent placement of central venous catheter in the right common carotid artery with the use of ultrasound guidance during emergency surgery for the total correction of Tetralogy of Fallot (ToF). This patient luckily had a favourable outcome despite this inadvertent catheter placement which was not recognised even after completion of surgery ...

OBJECTIVES: The objective of this study was to assess the utility of 3D printed heart models of congenital heart disease for preoperative surgical simulation. METHODS: Twenty patient-specific 3D models were created between March 2015 and August 2017. All operations were performed by a young consultant surgeon who had no prior experience with complex biventricular repair. All 15 patients with balanced ventricles had outflow tract malformations (double-outlet right ventricle in 7 patients, congenitally corrected transposition of great arteries in 5, transposition of great arteries in 1, interrupted aortic arch Type B in 1, tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries in 1)...

BACKGROUND: The optimal interval between serial cardiac magnetic resonance imaging (CMRI) scans for monitoring right ventricular (RV) enlargement in the setting of severe pulmonic valve regurgitation (PR) is unknown. The purposes of this study were to (1) determine the annual change in RV volume on serial CMRI scans and (2) identify the risk factors for rapid progression of RV enlargement. METHODS: A retrospective study of adults with postintervention native valve PR and ≥2 CMRI scans at Mayo Clinic Rochester from 2000 to 2015 was conducted...

BACKGROUND: Many patients with tetralogy of Fallot (TOF) who underwent surgical correction of their congenital cardiac malformation during infancy develop right ventricular dysfunction and exercise intolerance in the long term. The right ventricle (RV) dilates due to the development of severe pulmonary regurgitation (and secondary tricuspid insufficiency). To reduce RV dilation and improve exercise tolerance pulmonary valve replacement (PVR) is the common therapeutic strategy. Whether concomitant tricuspid valve repair (TVR) is beneficial in these pure volume-overload conditions is still unknown...

REVIEW
Hideki Tatewaki, Akira Shiose
In this review article, we describe pulmonary valve replacement (PVR) late after repaired Tetralogy of Fallot (TOF). Since the introduction of surgical intervention for patients with TOF in 1945, surgical management of TOF has dramatically improved early survival with mortality rates, less than 2-3%. However, the majority of these patients continue to experience residual right ventricular outflow tract pathology, most commonly pulmonary valve regurgitation (PR). The patients are generally asymptomatic during childhood and adolescence and, however, are at risk for severe PR later which can result in exercise intolerance, heart failure, arrhythmias, and sudden death...

BACKGROUND: Electrophysiologic (EP) and structural interventions in adult congenital heart disease (ACHD) are typically completed during separate hospital encounters. With planning/coordination, these cases can be combined. OBJECTIVES: We hypothesized that this integrated approach would yield patient and health system benefits. METHODS: Consecutive ACHD patients undergoing combined interventions were matched to controls with identical but separate procedures...

Right ventricular (RV) end-diastolic volume measured by cardiovascular magnetic resonance imaging (CMR) is a criterion for pulmonary valve replacement in patients with tetralogy of Fallot (TOF). We sought to determine if the ratio of echocardiographic, short-axis RV-to-left ventricular (LV) end-diastolic areas (EDA) could be used to predict RV volume on CMR. We retrospectively reviewed the echocardiograms of all patients with repaired TOF who underwent CMR at our institution from 2011 to 2015 and also had an echocardiogram within 6 months of the CMR...
