All About Cardiovascular System and Disorders

Adult survival is uncommon in all except: a. Ebstein's anomaly b. Pulmonary atresia with intact ventricular septum c. TGA d. Interrupted aortic arch

Bioresorbable vascular scaffolds or (bioabsorbable coronary stents) tend to restore the coronary configuration and systolo diastolic movements to those seen before implantation.

Coronary thrombus increased the rate of ischemic complications at 30 days and 3 fold increase of death and MI in the first year after intervention.

Transcatheter aortic valve implantation (TAVI) represents a minimally invasive alternative to conventional surgery (aortic valve replacement).

Partial fenestration of Fontan circuit leaving an ASD prevents rapid rise in venous pressure as it relieves excessive RA pressure in immediate postop period.

Initially that right atrium can function as a hydraulic pump to drive the pulmonary circulation when an atriopulmonary anastomosis is made in Fontan surgery for tricuspid atresia.

Potential long term problems after arterial switch operation are pulmonary stenosis, coronary abnormalities and dilatation of neoaortic root with AR.

In 1873 Kussmaul reported that in patients with constrictive pericarditis, the expected inspiratory collapse of neck veins was replaced by increased inspiratory distension.

Atrial scarring and arrhythmias following an atrial based repair of TGAs is an important concern which made arterial switch as the better choice.

TGA is the most common cyanotic congenital heart disease at birth.
