"Bubble contrast TTE" involves the injection of agitated saline into a vein, followed by an Echocardiographic study. The bubbles are initially detected in the right atrium and right ventricle. If bubbles appear in the left heart, it may indicate a shunt, such as a patent foramen ovale , atrial septal defect , ventricular septal defect or ...
A bubble echocardiogram is an extension of this that uses simple air bubbles as a contrast medium during this study and often has to be requested specifically. Although colour Doppler can be used to detect abnormal flows between the chambers of the heart (e.g., persistent (patent) foramen ovale ), it has a limited sensitivity .
Intravenous microbubbles (> 10 micrometers in diameter) from agitated normal saline that are normally obstructed by pulmonary capillaries (normally <8 to 15 micrometers) rapidly transit the lung and appear in the left atrium of the heart within 7 heart beats.
Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
Agitated saline can be used as contrast for blood flow and microbubbles for capillary blood flow contrast. Transthoracic echocardiogram (TTE): Echocardiogram of the heart through the thorax external to the body. Much easier to perform than TEE because it is non-invasive and takes less time, but has several disadvantages (namely clarity of images).
These microbubbles are composed of agitated saline solution, most of which are too large to pass through the capillaries (blood vessels) of the lungs. Therefore, the only ones that reach the left side of the heart pass through an abnormal connection between the two sides of the heart, known as a right-to-left shunt.
