There is a certain confusion as to the universal classification of coronary artery anomalies (CAAs), since the existing classifications are often fragmented and difficult to apply as they combine many anatomical, angiographic, and clinical elements. A practical global classification of CAAs for diagnostic and clinical purposes has not been proposed ...

We report a 10-month-old boy who underwent a bi-directional Glenn procedure and repair of coronary sinus orifice atresia. The left superior vena cava was the only vessel communicating with the coronary sinus in this case. The coronary sinus was allowed to communicate freely with the left atrium by creating a ...

Hypoplastic left heart syndrome is a rare but serious form of congenital cardiac disease, characterized by underdevelopment of the components of the left heart, rendering the left ventricle non-functional. Its aetiology is largely unknown, but there is certainly a genetic component. Prenatal diagnosis nowadays uncovers about half of cases. Postnatal ...

Definition of asphyxia Asphyxia is a Greek term and means loss of pulse (1). There is no clear definition of the term, though perinatal asphyxia or birth asphyxia often is defined as impaired placental- or pulmonary oxygen delivery to the neonate. As a consequence the neonate is going through a ...

Congenital anomalies of the coronary arteries occur in 0.2-1.2% of the general population; they cause 12% of sports-related sudden cardiac deaths and 1.2% of non-sports-related deaths. We review some of the substantial advances that have been made both, in the understanding of the embryonic development of the coronary arteries and ...

Left ventricular diverticulum is a rare congenital anomaly. In the adult population, the incidence was reported to be 0.26% in nonselected patients who underwent cardiac catheterization. Diverticula are usually localized near the apex and most often involve the inferior or anterior parietal walls of the left ventricle. In this report, ...

Ebstein's anomaly is a rare cardiac malformation that affects the tricuspid valve, right ventricle, and right atrioventricular junction. These anatomical and functional abnormalities cause important tricuspid regurgitation that results in right atrial and right ventricular dilatation and atrial and ventricular arrhythmias. Diagnosis is made by echocardiography. Operation includes tricuspid valve ...

Ebstein's anomaly is the most frequent cause of congenital tricuspid regurgitation. The coexistence of a mechanical heart prosthesis in a low-pressure circuit and poor compliance in the anticoagulant therapy contributed decisively to the appearance of recurrent mechanical heart valve thrombosis in these patients. A 49 years old female patient is ...

In embryology, a persistent connection of the left superior vena cava to the left atrium rarely coexists with a coronary sinus. We herein report an unusual case of persistent left superior vena cava terminating in a left atrium with normal coronary sinus, which was revealed at the time of permanent ...

Coronary sinus (CS) ostial obstruction decompressing through a left superior vena cava is a rare finding and presents unique risks to patients requiring a Glenn anastomosis for single-ventricle palliation. Preoperative diagnosis is imperative in order to avoid inadvertent ligation or coil occlusion. We report three cases with single-ventricle physiology and ...

Examination of the fetal heart has become an established part of mid-trimester anomaly scanning. Along side this has emerged the ability to diagnose congenital heart disease in the fetus with accuracy. Despite this, the development of screening programmes to look for fetal cardiac disease has only been partially successful. Furthermore, ...

One-and-a-half ventricle repair, consisting of endocardiectomy with tricuspid valve replacement and bidirectional cavopulmonary shunt, was performed on a patient with right ventricular endomyocardial fibrosis and right ventricular outflow tract obstruction. The patient made a smooth recovery. We believe that this repair provides good palliation for a subset of patients with ...

It is rare to find multiple fistulas arising from all three coronary arteries and draining into the left ventricle. Coronary angiography revealed this anomaly in a one-year-old girl with tricuspid atresia after conversion to the Fontan circulation. To the best of our knowledge, this is the first report of such ...

We report a case of unusual origin of cardiac angiosarcoma rising from the pulmonary trunk. The tumor caused severe obstruction of the right ventricular outflow tract with serious symptoms of right ventricular failure and tricuspid insufficiency. The angiosarcoma was surgically unresectable because of infiltration of the pulmonary artery and cardiac ...

Genes involved in the Notch signaling pathway have been shown to be critical regulators of cardiovascular development. In vitro studies have revealed that the Notch signaling pathway directly regulates transcription of hairy and enhancer of split-related (hesr) genes, encoding basic helix-loop-helix transcription factors. To assess the functional role of hesr ...

We used a genetic lineage-labeling system to establish the material contributions of the progeny of 3 specific cell types to the cardiac valves. Thus, we labeled irreversibly the myocardial (alphaMHC-Cre+), endocardial (Tie2-Cre+), and neural crest (Wnt1-Cre+) cells during development and assessed their eventual contribution to the definitive valvar complexes. The ...

OBJECTIVE: Congenital variations are known to be potential candidates for mechanical trauma leading to tricuspid valve lesions. For this reason, a detailed examination of heart valves as well as chordae tendineae should carefully be performed to clarify the reason of sudden death with no apparent cause. The aim of this ...

INTRODUCTION: Although in the treatment of common atrial flutter, the isthmus between the tricuspid valve annulus and the eustachian ridge is often chosen as the site for conduction block by radiofrequency ablation, the precise path of the flutter circuit remains unknown. We therefore investigated the propagation of the atrial flutter ...

The occurrence of pulmonary venous obstruction after total cavopulmonary connection with intraatrial lateral tunnel is a rare occurrence. We present two cases of hypoplastic left heart syndrome with restrictive interatrial communication presenting late after this type of modified Fontan repair. This occurred even after complete excision of the atrial septum ...
