An anomalous origin of right coronary artery from the left sinus of Valsalva is a rare congenital anomaly of the coronary arteries. We describe a 40-year-old male hypertensive and hyperlipidemic patient who presented with typical anginal pain with normal ECG and echocardiogram and abnormal exercise ECG Test Coronary angiography showed ...

Information generated by work on the human genome means that we now understand the genetic basis of many of the cardiac anomalies that present in the fetal and neonatal periods. This allows for an earlier and more definitive diagnosis of an underlying syndrome, although it does not replace the need ...

Nonimmune hydrops fetalis (NIHF) or generalized soft tissue edema and cavity effusions may be due to cardiovascular diseases, congenital infections, genitourinary malformations, thoracic masses, placental conditions, chromosomal abnormalities, and idiopathic. We report 32 cases of NIHF from among 429 neonates who underwent autopsies (incidence 7.45%). Sixteen cases (50%) had cardiovascular ...

Left ventricular noncompaction (LVNC) has been recently proposed as a specific form of cardiomyopathy. There have been few pathological series describing gross and microscopic findings of this entity, especially in children. We present findings of 14 hearts (13 autopsy and 1 explant) with LVNC (isolated and associated with congenital heart ...

We report a 4-year-old girl who underwent replacement of a bioprosthetic valve in the tricuspid position due to rare bioprosthetic dysfunction. The bioprosthetic valve showed marked tricuspid insufficiency as well as stenosis caused by the adhesion of the preserved native valve leaflets to the undersurface of the implanted bioprosthesis.

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 ...

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 ...
Cáceres-Lóriga Fidel Manuel - - 2005
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 ...
Kato Yasuyuki - - 2005
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, ...

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 ...
