EECP is most appropriate for people who are<br />

not receiving adequate relief from medications<br />

<strong>and</strong> would benefit from CORONARY ARTERY BYPASS<br />

GRAFT (CABG) but cannot, or choose not, to<br />

undergo the surgery. EECP is not appropriate for<br />

people who have uncontrolled HYPERTENSION or<br />

ARRHYTHMIA or who have bleeding disorders. There<br />

are no identified risks associated with EECP. Some<br />

people do find the pressure <strong>of</strong> the counterpulsations<br />

somewhat uncomfortable.<br />

fibroelastoma A noncancerous, connective tissue<br />

tumor that arises from the ENDOCARDIUM, usually<br />

on or near a HEART valve. Also called cardiac<br />

papillary fibroelastoma, this rare tumor can<br />

become serious or life threatening when it interferes<br />

with the function <strong>of</strong> a heart valve. Fibroelastomas<br />

most commonly form on or near the aortic<br />

valve or the tricuspid valve. They may become<br />

large enough to prevent the valve’s proper function<br />

or to block the flow <strong>of</strong> BLOOD through the<br />

valve. A fibroelastoma may also create turbulence<br />

in the heart, allowing blood to pool <strong>and</strong> clot. Generally<br />

fibroelestomas cause no symptoms <strong>and</strong> cardiologists<br />

may detect them incidentally during<br />

echocardiogram for other purposes. Because fibroelastomas<br />

pose such a significant risk for clotting<br />

<strong>and</strong> STROKE, cardiologists typically recommend surgery<br />

to remove them. Cardiologists do not know<br />

what causes fibroelastomas, though there is some<br />

debate whether they are congenital or acquired.<br />

gallop A pair <strong>of</strong> extra HEART SOUNDS the cardiologist<br />

can hear with the bell <strong>of</strong> the STETHOSCOPE during<br />

diastole, so-named because they occur in rapid<br />

succession <strong>and</strong> sound like the hooves <strong>of</strong> a galloping<br />

horse. The characteristic sound is that <strong>of</strong> a<br />

deep-toned thud. A gallop <strong>of</strong>ten exists with tachycardia<br />

(rapid, regular HEART RATE) <strong>and</strong> generally<br />

signals ventricular dysfunction such as might follow<br />

HEART ATTACK.<br />
