- Anastomosis – A Cross connection between two tubes. In surgery, anastomosis refers to a connection between two vessels made by surgical stitching or stapling.
- Aneurism – Local dilatation of a blood vessel.
- Angina pectoris or Chest angina is severe chest pain due to coronary artery stenosis.
- Arrest – cardiac arrest, sudden cessation of heart function.
- Arrhythmia – irregular heart rhythm
- Atrial fibrillation – lack of atrial contraction in which heart atria flicker and trigger completely irregular ventricle contraction
- Atherosclerosis – Process of cholesterol plaques settling and subsequent inner arterial layers degeneration.
- Atrial flatter – similar to atrial fibrillation except that some very fast and inefficient atrial contraction exists.
- Bentalova procedure – Aortic surgery in which aortic valve and ascending aorta are replaced altogether with a conduit graft while coronary artery ostia are reimplanted on the graft .
- Aortic dissection – dissection of aortic wall layers by blood flow. Severe condition and surgical emergency.
- Dyspnea – Shortness of breath
- Graft – Generally, a blood vessel harvested from a patient and used for bypassing the stenotic artery. In transplant surgery, denotes transplanted organ.
- Fibrillation – Flickering of heart chambers. Ventricular fibrillation is a severe malignant arrhythmia resulting in sudden death.
- Hypoxia – Decreased blood oxygen level.
- Emboly – Blood vessel obstruction by a cloth or other material originating from somewhere in the human body.
- Infraction – Tissue death
- Ischemia – Tissue oxygen deprivation
- Insufficiency – Failure, heart failure or incompetence valve insufficiency
- Clinical death – Heart arrest. A possibly reversible condition that if untreated leads to brain death.
- Come – Deep state of prolonged unconsciousness.
- NYHA classification – New York Heart Association classification of heart failure. Class I -no limitations of activity; Class II – slight limitation in everyday physical activity; Class III – ordinary activity results in shortness of breath; Class IV – dyspnea at rest
- Brain death – brain cell death, irreversible condition.
- Paresis – Decrease mobility due to peripheral or central nerve damage.
- Plegia – Complete inability to move due to peripheral or central nerve damage.
- Pulmonary embolism – Complete pulmonary artery blockage by cloth mostly from peripheral vein.
- Prolapse – Valve incompetence. Valve leaflets do not close therefore result in blood regurgitation in the opposite direction.
- Regurgitation – Blood back flow due to valve incompetence.
- Syncope – Sudden loss of consciousness due to a drop in blood pressure
- Stenosis – blood vessel blockage
- Thrombus – A blood clot
- Thrombosis – Blood clot formation
