The high spatial resolution of cardiac computed tomography (CT) and cardiac magnetic resonance (CMR) permit the diagnosis of congenital ventricular outpouchings (CVOs), including congenital ventricular diverticula (CVD), congenital ventricular aneurysms (CVA), clefts, and crypts. A unique classification has not been established, and these terms are used interchangeably with confounding terminology. Moreover, their significance is not univocal. A research was performed using PubMed on six subjects: (1) congenital left ventricular outpouchings; (2) congenital ventricular diverticulum; (3) congenital ventricular aneurysm; (4) ventricular clefts; (5) ventricular crypts; and (6) ventricular crevices...

Congenital left ventricular aneurysm or diverticulum are rare cardiac malformations described in 809 cases since the first description in 1816, being associated with other cardiac, vascular or thoraco-abdominal abnormalities in about 70%. It appears to be a developmental anomaly, starting in the 4th embryonic week. In an experimental study, targeted knockdown of cardiac troponin T in the chick was performed at day 3, after the heart tube has formed. Morpholino treatment of gene TNNT2 at this stage led to the development of left ventricular diverticula (LVD) in the primitive left ventricular wall...

After an arterial switch operation (ASO), serial imaging is necessary to monitor for maladaptive changes. We compared cardiac magnetic resonance imaging (CMR) to 2-D transthoracic echocardiography (TTE) in assessing post-operative ASO patients. We performed a retrospective review of patients at a single tertiary care center who underwent an ASO and subsequently had a CMR performed from 7/2010 to 7/2016. Those with single ventricle anatomy, congenitally corrected transposition of the great arteries, or previous atrial switch operation were excluded...

Congenital aneurysms and diverticula of the heart are rare anomalies and their prenatal diagnosis is challenging. Fetuses with suspected cardiac aneurysms on ultrasound (US) screening should undergo targeted fetal echocardiography, postnatal imaging, and follow-ups. Herein, we describe the second trimester US scan and postnatal cardiac magnetic resonance imaging (MRI) findings of a baby girl with concurrent septal and right ventricular cardiac aneurysms. Other cardiac and extra-cardiac structures were normal...

BACKGROUND: Fetal cardiovascular magnetic resonance (CMR) imaging may provide a valuable adjunct to fetal echocardiography in the evaluation of congenital cardiovascular pathologies. However, dynamic fetal CMR is difficult due to the lack of direct in-utero cardiac gating. The aim of this study was to investigate the effectiveness of a newly developed Doppler ultrasound (DUS) device in humans for fetal CMR gating. METHODS: Fifteen fetuses (gestational age 30-39 weeks) were examined using 1...

BACKGROUND: Coarctation of the aorta (CoA) is one of the most common congenital heart defects. Due to improved surgical techniques, most patients live into adulthood. However, late complications including hypertension, recoarctation and arrhythmias are common. The autonomic nervous system (ANS) might play a role in the pathology. The aim of this study was to evaluate cardiac ANS activity and cardiac function in children after CoA repair and investigate the relationship between the two...

The aim of the study was to evaluate systemic right ventricular (RV) dyssynchrony in patients with congenitally corrected transposition of the great arteries (CCTGA) and transposition of the great arteries (TGA) with New York Heart Association functional class (NYHA FC) < III. We used cardiac magnetic resonance (CMR) to evaluate the dyssynchrony and assessed whether RV dyssynchrony can be predictive of major cardiac events in their early stages in these patients. We enrolled 71 consecutive, NYHA FC < III patients with systemic RV who underwent CMR between April 1995 and December 2016...

RATIONALE: Left atrial appendage aneurysms (LAAA) are rare. Patients with LAAA are often diagnosed incidentally or after cardiac tachyarrhythmia or systemic thromboembolism happen. Early diagnosis and surgical resection is of utmost importance to prevent hazardous adverse events. PATIENT CONCERNS: We present a case of 46-year-old man with congenital LAAA. The individual in this manuscript has given written informed consent to publish these case details. DIAGNOSES: Imaging studies, such as echocardiography, cardiovascular computed tomography (CT) and magnetic resonance imaging (MRI), demonstrated the large cavity arising from the left atrial appendage...

Cardiac imaging is central to today's pediatric cardiology practice not only to diagnose structural congenital defects and delineate cardiac and extracardiac anatomy but also for determining the hemodynamic impact of the structural defects and acquired pediatric diseases. Not so long ago, clinicians had to heavily rely on angiography as the main cardiac imaging modality to visualize the heart. Particularly, the development of echocardiography in the 1970s and 1980s together with the development of magnetic resonance imaging (MRI) and computed tomography (CT) resulted in a non-invasive diagnostic revolution with diagnostic catheterization becoming obsolete apart for very specific indications...

BACKGROUND: Unilateral absence of the pulmonary artery (UAPA) is a rare congenital malformation often associated with other cardiac anomalies; however it may occur as an isolated lesion. Isolated absence of the right pulmonary artery is twice more frequent than that of the left pulmonary artery. Patients with isolated UAPA are usually asymptomatic at birth; thereafter they may develop a progression of symptoms such as exercise intolerance, dyspnea, chest pain, hemoptysis and recurrent pulmonary infections...

Left ventricular noncompaction cardiomyopathy (LVNC) is characterized by compact and trabecular layers of the left ventricular myocardium. This cardiomyopathy may occur with congenital heart disease (CHD). Single cases document co-occurrence of LVNC and heterotaxy, but no data exist regarding the prevalence of this association. This study sought to determine whether a non-random association of LVNC and heterotaxy exists by evaluating the prevalence of LVNC in patients with heterotaxy. In a retrospective review of the Indiana Network for Patient Care, we identified 172 patients with heterotaxy (69 male, 103 female)...

INTRODUCTION: Our goal was to assess the diagnostic performance of magnetic resonance imaging (MRI) as a single method to diagnose pulmonary hypertension (PH) compared to right heart catheterization (RHC), computed tomography (CT), and ventilation/perfusion (V/Q) scintigraphy. METHODS: We identified 35 patients diagnosed with PH by RHC in our institution who have also undergone a CT, a scintigraphy, and an MRI within a month. All cases were discussed in multidisciplinary meetings...

Tracheobronchial anomalies are common in congenital heart disease (CHD), including tracheobronchial stenosis, tracheal bronchus, cardiac bronchus, and bronchial isomerism, which can cause varying degrees of respiratory illness. It is necessary to assess tracheobronchial anomalies and make a preoperative airway evaluation. Multi-slice computed tomography (MSCT) and cardiac magnetic resonance imaging (MRI) are the most effective noninvasive modalities for the diagnosis of CHD and the associated tracheobronchial anomalies...

Exercise-associated benefits on the cardiovascular systems are well established. Although exercise-associated sudden cardiac death is rare, most deaths in young athletes are due to hereditary or congenital cardiac diseases. Athletic adaptation itself is associated with several structural changes that overlap those observed in individuals with cardiomyopathies, often leading to dilemmas for the clinician regarding life-changing decisions including advice against competitive sports participation. Cardiac magnetic resonance plays an increasingly important role in helping to establish an accurate diagnosis in these individuals...

Pulmonary atresia with intact ventricular septum (PA-IVS) is a rare complex cyanotic congenital heart disease with heterogeneous morphological variation. Prenatal diagnosis allows for developing a safe plan for delivery and postnatal management. While transthoracic echocardiography allows for detailed delineation of the cardiac anatomy, additional imaging modalities such as computed tomography, magnetic resonance imaging, and catheterization may be necessary to further outline features of the cardiac anatomy, specifically coronary artery anatomy...

Ebstein anomaly is a congenital disorder of right ventricular myocardial development, which affects the tricuspid valve in addition to the right ventricular myocardium. Cardiac imaging by transthoracic echocardiography and cardiac magnetic resonance imaging are the key modalities used to assess timing and type of surgery. In this article, we review the current standards of echocardiographic and magnetic resonance imaging in Ebstein anomaly.

Phase-contrast cine MRI (PC-MRI) is the gold-standard non-invasive technique for measuring vessel blood flow and has previously been applied in the human fetal circulation. We aimed to assess the feasibility of using PC-MRI to define the distribution of the fetal circulation in sheep. Fetuses were catheterized at 119-120 days gestation (term, 150 days) and underwent MRI at 123 days gestation under isoflurane anesthesia, ventilated at a FiO2 of 1.0. PC-MRI was performed using a fetal arterial blood pressure catheter signal for cardiac triggering...

Advances in medical diagnosis reveal that coronary artery aneurysms (CAAs) may develop in several clinical scenarios and manifest variable symptoms, imaging appearances, and outcomes. Aneurysms are pathologically classified into three groups: atherosclerotic, inflammatory, and noninflammatory. The last category is associated with congenital, inherited, and connective tissue disorders. Overlap exists among the groups, because secondary atherosclerotic change may be present in an aneurysm of any cause. Atherosclerosis is the most common cause of CAAs in adults, and inflammation is considered the underlying mechanism...
