mitral valve repair
Surgical reconstruction of the mitral valve to restore normal function while preserving the native valve structure.
cardioplegic arrest
Intentional cessation of cardiac activity using cardioplegic solution to create a motionless surgical field.
cardiopulmonary bypass
Technique using a heart-lung machine to temporarily take over cardiac and pulmonary function during surgery.
Cardiopulmonary Exercise Testing
Comprehensive assessment combining exercise testing with respiratory gas analysis to evaluate cardiovascular and pulmona...
cardiotomy sucker
Surgical instrument that removes blood and debris from the operative field while returning blood to the CPB circuit.
chordal reconstruction
Surgical repair technique using artificial or native tissue to replace or repair damaged mitral valve chordae tendineae.

Newly developed aortic valve stenosis in previously normal valve, distinct from progression of existing disease.
dehiscence
Partial or complete separation of surgical wound edges, particularly concerning sternal wound healing.
Diastolic Dysfunction
Impaired ventricular relaxation and filling during diastole, often with preserved systolic function.
ECMO
Extracorporeal membrane oxygenation providing temporary cardiac and pulmonary support.
ejection fraction
The percentage of blood pumped out of the left ventricle with each heartbeat, used as a measure of cardiac function.
Elephant Trunk Procedure
Two-stage surgical approach for extensive aortic disease involving initial placement of a Dacron graft in the arch and d...
endocarditis prophylaxis
Preventive antibiotic therapy to reduce risk of infective endocarditis in high-risk patients.
endovascular
Referring to procedures performed inside blood vessels using catheters and guidewires rather than open surgical techniqu...
epicardial pacing
Temporary cardiac pacing using electrodes placed directly on the heart's surface during cardiac surgery.
