TAVR TAVR
Transcatheter aortic valve replacement, a minimally invasive procedure to replace the aortic valve without open surgery.
hybrid procedure
Combined surgical and interventional approach performed in a specialized operating room equipped with advanced imaging c...
IABP
Intra-aortic balloon pump, a mechanical circulatory support device used to augment cardiac output and coronary perfusion...
intra-aortic balloon pump
A mechanical circulatory support device that assists cardiac function by inflating and deflating a balloon in the aorta.
intraoperative TEE
Real-time transesophageal echocardiographic monitoring used during cardiac surgery for assessment and guidance.
LIMA
Left internal mammary artery, the preferred conduit for coronary artery bypass grafting due to excellent long-term paten...
maze procedure
Surgical treatment for atrial fibrillation using incisions or ablation to interrupt abnormal electrical pathways.
mechanical circulatory support
Devices that assist or replace cardiac function, including ventricular assist devices, ECMO, and intra-aortic balloon pu...
median sternotomy
Standard surgical approach involving division of the sternum along its midline to access the heart.
minimally invasive cardiac surgery
Cardiac surgical procedures performed through smaller incisions or ports rather than full sternotomy.
mitral valve repair
Surgical correction of mitral valve dysfunction while preserving the patient's native valve tissue and apparatus.
myectomy
Surgical removal of hypertrophied muscle tissue, typically from the interventricular septum in hypertrophic cardiomyopat...
myocardial preservation
Techniques used during cardiac surgery to protect the heart muscle from ischemic injury.
myocardial protection
Strategies employed during cardiac surgery to prevent heart muscle damage during periods of interrupted blood flow.
myocardial revascularization
Surgical restoration of blood supply to ischemic heart muscle through bypass grafting.
myocardial stunning
Temporary mechanical dysfunction of viable myocardium following brief ischemia, despite restoration of normal perfusion.
myocardial viability study
Imaging assessment to determine whether dysfunctional myocardium contains viable tissue that could benefit from revascul...
Norwood procedure
A three-stage palliative surgical approach for hypoplastic left heart syndrome, involving reconstruction of the aortic a...
OPCAB
Off-pump coronary artery bypass surgery performed on a beating heart without cardiopulmonary bypass.
papillary muscle rupture
Catastrophic complication where a papillary muscle tears, usually following myocardial infarction, causing severe mitral...
patch augmentation
The use of a patch to enlarge or reinforce cardiac structures, commonly valves, vessels, or septal defects.
pericardial effusion
Abnormal accumulation of fluid in the pericardial space, potentially requiring surgical drainage or window creation.
pericardiotomy
Surgical incision of the pericardium to access the heart or relieve pericardial constraint.
perioperative myocardial infarction
Heart attack occurring during or within 48 hours of cardiac surgery, often related to inadequate myocardial protection.
plegia solution
Cardioplegic solution used to induce cardiac arrest and protect the myocardium during cardiac surgery.
