Wolff Parkinson White Syndrome

Wolff-Parkinson-White syndrome (WPW) is a congenital malformation involving the presence of an abnormal conductive tissue between the atria and ventricles which is frequently associated with the appearance of supraventricular tachycardia. It requires activation of the ventricles before the normal contraction  (pre-excitation) through an extra ventricular path, called accessory, bypasses the AV node.   Classical electrocardiographic […]

Aortic Aneurysm

The aorta is the largest artery in the human body. It stretches from the aortic valve (from the heart) until the middle third of the abdomen, where it divides into the two common iliac arteries. It carries oxygenated blood necessary for the body’s metabolism. The aorta is divided into two major segments: thoracic aorta and […]

Atrial Septal Defect

Is the most common congenital cardiac malformation in adults. It can be of 3 kinds: 1. Sinus venosus defect -it is located in the upper portion of the interatrial septum, close to the  vena cava. May cause abnormal pulmonary vein drainage into the right atrium.  2. Ostium Secundum defect -is met quite frequently (70-75%). Attention, […]

Ventricular Septal Defect

Ventricular septal defect (VSD) is one of the most common congenital heart defects, also known as hole in the heart. Practically there is a hole in the wall that separates the two ventricles of the heart, allowing oxygen-rich and oxygen-poor blood to mix.   Before birth, the right and the left lower chambers of the […]

Patent Ductus Arteriosus

Patent ductus arteriosus is a communication between the aorta and pulmonary artery in the fetus, which at birth physiologically closes due to increased blood pressure and decrease oxygen prostaglandins. It normally closes in the first 10-15 hours of life, the patent ductus arteriosus being the result of not closing it. Patent ductus arteriosus is more […]
