RESUMO
BACKGROUND AND AIMS: Transcatheter pulmonary valve implantation (TPVI) is indicated to treat right-ventricular outflow tract (RVOT) dysfunction related to congenital heart disease (CHD). Outcomes of TPVI with the SAPIEN 3 valve that are insufficiently documented were investigated in the EUROPULMS3 registry of SAPIEN 3-TPVI. METHODS: Patient-related, procedural, and follow-up outcome data were retrospectively assessed in this observational cohort from 35 centres in 15 countries. RESULTS: Data for 840 consecutive patients treated in 2014-2021 at a median age of 29.2 (19.0-41.6) years were obtained. The most common diagnosis was conotruncal defect (70.5%), with a native or patched RVOT in 50.7% of all patients. Valve sizes were 20, 23, 26, and 29â mm in 0.4%, 25.5%, 32.1%, and 42.0% of patients, respectively. Valve implantation was successful in 98.5% [95% confidence interval (CI), 97.4%-99.2%] of patients. Median follow-up was 20.3 (7.1-38.4) months. Eight patients experienced infective endocarditis; 11 required pulmonary valve replacement, with a lower incidence for larger valves (P = .009), and four experienced pulmonary valve thrombosis, including one who died and three who recovered with anticoagulation. Cumulative incidences (95%CI) 1, 3, and 6 years after TPVI were as follows: infective endocarditis, 0.5% (0.0%-1.0%), 0.9% (0.2%-1.6%), and 3.8% (0.0%-8.4%); pulmonary valve replacement, 0.4% (0.0%-0.8%), 1.3% (0.2%-2.4%), and 8.0% (1.2%-14.8%); and pulmonary valve thrombosis, 0.4% (0.0%-0.9%), 0.7% (0.0%-1.3%), and 0.7% (0.0%-1.3%), respectively. CONCLUSIONS: Outcomes of SAPIEN 3 TPVI were favourable in patients with CHD, half of whom had native or patched RVOTs.

OBJECTIVE: Studies suggest that men who undergo assisted reproductive technologies (ART) may have a higher risk of cardiovascular disease; however, limited data on this matter is available. This observational pilot study aimed to investigate the overall vascular health of fathers with history of intracytoplasmic sperm injection (ICSI) compared to fathers whose partners conceived spontaneously. METHODS: Diet quality, physical activity, sedentary behavior as well as overall vascular function including the assessment of pulse wave analysis, intima-media thickness (cIMT), arterial stiffness of the common carotid artery (CCA) and blood lipids, were evaluated. RESULTS: A total of 34 fathers with history of ICSI and 29 controls (48.49 [46.32 - 57.09] years vs. 47.19 [40.62 - 55.18] years, p = 0.061) were included. After adjusting for age, no significantly increased cardiovascular risk was detected regarding vascular function. CONCLUSIONS: The results suggest an unaltered cardiovascular risk profile in fathers with history of ICSI. In the future, prospective multicenter studies are required to validate these preliminary results.

Tetralogy of Fallot (TOF) is the most common cyanotic heart defect. TOF consists of the combination of four anomalies (Fig. 35.1): (1) a large malalignment ventricular septal defect, (2) an obstruction of the right ventricular outflow tract (usually infundibular and valvular pulmonary stenosis with a small pulmonary valve annulus and supravalvular stenosis, (3) an aorta that "overrides" the ventricular septal defect, and (4) right ventricular hypertrophy. TOF represents 4-8% of congenital heart defects. Specific variations of TOF include all forms of pulmonary atresia with VSD and absent pulmonary valve syndrome. In addition, the left and right main pulmonary arteries may be stenotic or hypoplastic. In these cases, there may be major aortopulmonary collateral arteries (MAPCAs) which are vessels arising from the aorta or the subclavian arteries that supply segments of the pulmonary arterial tree. Additional variations include an ASD (Pentalogy of Fallot), a right aortic arch, and coronary abnormalities.

d-Transposition of the great arteries (d-TGA) is the most common form of congenital heart disease that presents with cyanosis in a newborn. The aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. It constitutes 3-5% of all congenital heart defects. In a simple d-TGA (about two-thirds of patients), there is no other cardiac abnormality other than a patent foramen ovale (PFO) and a patent ductus arteriosus (PDA). In a complex d-TGA additional cardiac abnormalities such as VSD, pulmonary stenosis or coronary abnormalities are present. About one-third to 40% of patients with d-TGA have an associated ventricular septal defect. Among patients with d-TGA, 6% of those with intact ventricular septum and 31% of those with ventricular septal defect have associated pulmonary stenosis. Coronary abnormalities are of importance with regard to the complexity of surgical repair.

The following semilunar valve defects and aortic arch anomalies are called simple defects because there is a single problem that can be well described. Based on the degree of malformation and hemodynamic consequence, these simple lesions can however be life threatening immediately after birth. They all affect either the left or right outflow tract or the aortic arch.

There are two major coronary arteries that arise normally directly above the aortic valve in the sinus. The left main coronary artery (LCA or LMCA) arises from the left coronary sinus and divides shortly after its origin into the left anterior descending and the circumflex coronary arteries (LCX). Branches of the left anterior descending (LAD) coronary artery include the left conus, septal, and diagonal arteries. Branches of the circumflex coronary artery may include the sinus node artery, Kugel's artery, marginal arteries, and the left atrial circumflex artery (Fig. 47.1). The LAD follows the interventricular septum to the apex, the LCX turns posterior, follows the atrioventricular groove between the left atrium and ventricle to the coronary sinus. Branches of the right coronary artery (RCX) include the conal branch, the sinus node artery, an atrial branch, the right ventricular muscle branches (including the acute marginal branch), the posterior descending coronary artery, the atrioventricular node artery, and septal branches (Fig. 47.2). The RCX follows the atrioventricular groove between the right atrium and ventricle. The "dominant coronary artery" is the one giving rise to the posterior descending coronary artery. It originates from the right coronary artery in 80% of people.

Ebstein anomaly is a rare congenital heart defect, accounting for less than 1% of cardiac malformations and occurring in approximately 1 out of 210,000 live births. It is characterized by an abnormality of the tricuspid valve, where the valve is positioned lower than normal in the right ventricle. Although primarily a tricuspid valve defect, the right ventricle itself is often structurally abnormal and weakened (myopathic).

Atrioventricular septal defects (AVSDs) consist of a number of cardiac malformations that result from abnormal development of the endocardial cushions. AVSDs occur in 0.19 of 1000 live births and constitute 4-5 % of congenital heart defects. AVSDs can be categorized as incomplete (or partial) or complete, and intermediate or transitional.

Situs abnormalities may occur in many and most often more complex congenital cardiac malformations. These conditions are collectively referred to as heterotaxy syndromes, derived from the Greek words "heteros" meaning different and "taxos" meaning orientation or arrangement. Clinically, heterotaxy spectrum encompasses defects in the left-right laterality and arrangement of visceral organs. "Situs" is derived from Latin and is the place where something exists or originates. In human anatomy, situs can be solitus (derived from Latin, meaning "normal"), inversus, or ambiguus. Heterotaxy syndrome represents an intermediate arrangement of internal organs between situs solitus and situs inversus, also known as "situs ambiguous." Situs ambiguus describes an abnormal distribution of major visceral organs within the chest and abdomen. The determination of situs as normal, inversus, or ambiguus is primarily based on the location of unpaired organs such as the spleen, liver, stomach, and intestines. Diagnosis is made by clinical examination, echocardiography, a chest X-ray (position of the heart, stomach, and liver), and ultrasound of the abdominal organs. Situs is considered solitus if the left atrium, spleen, stomach, and the trilobed lung are on the left side and the liver and bilobed lung are on the right side. Situs ambiguus is present if the location of unpaired structures is random or indeterminate even after detailed and appropriate imaging. Situs inversus results when the arrangement of the thoracic and abdominal organs is mirrored. Individuals with situs inversus or situs solitus do not experience fatal dysfunction of their organ systems, as general anatomy and morphology of the abdominothoracic organ-vessel systems are conserved.

Although the terms "single ventricle" and "univentricular heart" are frequently used to describe a variety of complex congenital heart defects, in fact, nearly all hearts have two ventricles, although one of the two may be too small to be functional. A better term for these hearts would therefore be "functional single ventricle."

Truncus arteriosus (TA, also known as common arterial trunk) consists of only one great artery ("the truncus") with a semilunar valve (truncus valve) arising from the heart and an additional ventricular septal defect and (Fig. 50.1). This great artery is positioned above the ventricular septal defect and gives rise to the coronary arteries, the pulmonary arteries, and the aortic arch. Historically, TA has been classified by Collet and Edwards in three types, where in type I there was a common pulmonary artery truncus, in type II the left and right PA arise separately but close to each other, in type III both PA arise independently; in addition, there was a type IV that was later characterized as pulmonary atresia with VSD and major aortopulmonary collateral arteries arising from the descending aorta.

Hypoplastic left heart syndrome (HLHS) is a complex congenital heart defect characterized by several abnormalities that result in a significantly underdeveloped left ventricle and severe hypoplasia of the ascending aorta, often leading to retrograde perfusion. These abnormalities include aortic valve atresia or severe stenosis, accompanied by a severely hypoplastic aortic valve annulus (Fig. 59.1). Mitral valve atresia, hypoplasia, and/or stenosis with a hypoplastic valve annulus with or without a ventricular septal defect can also contribute to the development of HLHS. Endocardial fibroelastosis and sinusoids may be present as well. The interatrial septum can either be closed or the foramen ovale severely stenotic. Other malformations, such as anomalous pulmonary venous drainage or variations of the systemic veins, may coexist. It is also common to observe a coarctation of the aorta in these cases.

Cardiomyopathies are a group of diseases that primarily affect the heart muscle, leading to mechanical or electrical dysfunction of the heart. They can be categorized into primary and secondary forms. Primary cardiomyopathies can be further classified as congenital, acquired, or mixed. In terms of the heart muscle itself, there are five distinct types of cardiomyopathies: hypertrophic cardiomyopathy, dilated or congestive cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic (right ventricular) dysplasia, and noncompaction cardiomyopathy. While cardiomyopathies primarily affect the heart, they can also have systemic manifestations, impacting other organs and potentially causing progressive debilitation, heart failure, or even death.

Total anomalous pulmonary venous return (TAPVR) is rare (accounting for about 1% of all CHD) and can occur as a single lesion or in combination with other types of CHD (such as heterotaxy or HLHS). TAPVR is defined as an abnormal connection where all pulmonary veins do not drain into the left atrium but into the right atrium either directly or through a vein that is connected to the right atrium. TAPVR can be divided into four anatomic groups (Fig. 32.1): (1) supracardiac (about 55%), (2) cardiac (about 30%), (3) infracardiac (about 13%), and (4) mixed (very rare). In addition, it can be divided into two physiological types: nonobstructed and obstructed. Embryologically, all pulmonary veins usually connect to a pulmonary venous confluence that connects to the left atrium. If this connection does not occur, the pulmonary venous confluence connects to a systemic vein instead.

Increased aortic stiffness predisposes cardiac afterload and influences cardiac function. Congenital heart diseases involving aortic arch malformation and extended cardiovascular surgery, i.e. univentricular heart diseases, can lead to increased aortic stiffness. This study aimed to investigate whether Fontan patients (FO) have increased aortic stiffness within distinct aortic segments, and whether these parameters relate to Fontan-specific haemodynamics. In a prospective case-control study, 20 FO and 49 heart-transplanted control subjects with biventricular circulation underwent invasive cardiac catheterisation. We invasively measured pulse wave velocity (PWV) in the ascending aorta and along the entire aorta. Haemodynamic parameters, including end-diastolic pressure, pulmonary artery pressure, the cardiac index and systemic vascular resistance index were also assessed. FO exhibited significantly higher ascending aorta PWV (aPWV) than controls (FO: 7.2 ± 2.4 m/s|Controls: 4.9 ± 0.7 m/s, p < 0.001) and compared to the inner group central aorta PWV (cPWV; FO: 5.5 ± 1.2 m/s|Controls: 5.3 ± 1.0 m/s). Multivariate analysis confirmed this aPWV elevation in FO even after adjusting for age and BMI. aPWV and cPWV were almost identical within the control group. Correlation analyses revealed associations between cPWV and blood pressure in controls, while correlations were less apparent in FO. We detected no significant association between the aPWV and other haemodynamic parameters in any of our groups. FO exhibit increased aPWV, indicating specific vascular stiffness in the ascending aorta, while their overall aortic stiffness remains comparable to controls. Further research is needed to understand the implications of these findings on Fontan circulation and long-term cardiovascular health. CENTRAL MESSAGE: Fontan patients show increased aortic arch pulse wave velocity, suggesting specific vascular stiffness. PERSPECTIVE STATEMENT: Our study offers rare insights into pulse wave velocity in Fontan patients, highlighting increased arterial stiffness in the aortic arch. Vascular stiffness was particularly increased in the area of surgical reconstruction. This indicates the need for further research on vascular stiffness in Fontan circulation to understand its impact on cardiovascular health.

RESUMO
BACKGROUND: Energy drinks (EDs) are popular beverages among minors. To date, clinical studies investigating ED-induced effects on the pediatric cardiovascular system are sparse. This study aimed to investigate the effects of a single, bodyweight-adjusted ED dosage on 24-h ambulatory blood pressure monitoring (ABPM) in healthy children and adolescents. METHODS: This study was a randomized, single-blind, placebo-controlled, crossover clinical trial. Study participants received a single, bodyweight-adjusted ED amount or a placebo drink on 2 consecutive days at similar morning hours. Twenty-four-hour ABPM was assessed via an automated oscillometric blood pressure device after beverage consumption on both study days. RESULTS: A total of 17 healthy children and teenagers (13.90 (12.29-17.89) years) were included in the final analysis. The ED consumption led, compared to the placebo intake, to a significantly higher 24-h systolic (115.90 (110.22-118.04) vs. 110.64 (108.09-115.45) mmHg, p = 0.013) and diastolic blood pressure (66.08 (64.20-68.32) vs. 62.63 (61.40-66.46) mmHg, p = 0.005). CONCLUSIONS: The single, bodyweight-adjusted ED consumption is linked with a significantly higher systolic as well as diastolic 24-h blood pressure in healthy children and adolescents. Minors, particularly those with an increased cardiovascular morbidity, should be discouraged from drinking EDs. IMPACT: Energy drinks (EDs) are consumed by many children and teenagers. While adverse cardiovascular events after ED consumption were reported in the literature, the effects of these beverages on the pediatric 24-h blood pressure profile have not been systematically evaluated yet. In our manuscript, we demonstrate for the first time that acute ED consumption is associated with a significantly higher 24-h systolic blood pressure and diastolic blood pressure in healthy minors.
