aortic arch reconstruction
Complex surgical repair of the aortic arch for congenital anomalies or acquired disease.
hemothorax
Accumulation of blood in the pleural space, typically following trauma or surgical procedures.
homograft
A valve or vascular conduit harvested from a human donor, used for cardiac or vascular reconstruction.
IABP
Intra-aortic balloon pump, a mechanical circulatory support device that augments coronary perfusion and reduces cardiac...
intimal hyperplasia
Abnormal thickening of the inner arterial wall layer, commonly occurring at surgical anastomoses and contributing to gra...
intraoperative TEE
Transesophageal echocardiography performed during cardiac surgery for real-time monitoring.
LIMA
Left internal mammary artery, the preferred arterial conduit for coronary bypass grafting.
lobectomy
Surgical removal of an entire lobe of the lung, typically performed for lung cancer treatment.
mammary artery
The internal thoracic artery commonly used as a conduit for coronary artery bypass grafting, particularly to the left an...
mediastinal lymph node dissection
Systematic removal of lymph nodes from the mediastinum during thoracic cancer surgery for staging and treatment.
mediastinal shift
Displacement of mediastinal structures from their normal midline position, often indicating underlying pathology.
mediastinoscopy
Minimally invasive procedure to examine and biopsy lymph nodes in the mediastinum.
minimally invasive cardiac surgery
Cardiac procedures performed through smaller incisions than traditional median sternotomy.
minimally invasive mitral surgery
Mitral valve surgery performed through smaller incisions using specialized techniques and instruments.
mitral valve repair
A surgical procedure to restore function of the mitral valve rather than replacing it entirely.
myectomy
Surgical removal of a portion of heart muscle, typically performed to relieve obstruction in hypertrophic cardiomyopathy...
myocardial protection
Techniques used during cardiac surgery to preserve heart muscle function while the heart is stopped and bloodless.
myocardial revascularization
Surgical restoration of blood flow to areas of heart muscle affected by coronary artery disease.
myocardial stunning
Temporary myocardial dysfunction that persists after restoration of blood flow following ischemia.
off-pump CABG
Coronary artery bypass surgery performed on the beating heart without cardiopulmonary bypass support.
pannus
Fibrous tissue overgrowth that can obstruct prosthetic heart valves or interfere with cardiac function.
paravalvular leak
Abnormal blood flow around the periphery of a prosthetic heart valve due to incomplete sealing.
perfusion pressure
The driving pressure that determines blood flow through tissues during cardiopulmonary bypass or organ perfusion.
pericardial effusion
Abnormal accumulation of fluid in the pericardial space surrounding the heart, which may impair cardiac filling.
pericardial friction rub
A harsh, grating sound heard on auscultation caused by inflamed pericardial surfaces rubbing together.
