Septal defect repair
Septal defect repair is the closure of an abnormal opening between the heart's chambers, most often an atrial or ventricular septal defect, by surgery or a transcatheter occluder device.
Septal reduction therapy
Septal reduction therapy (SRT) is a group of invasive treatments for obstructive hypertrophic cardiomyopathy, chiefly surgical septal myectomy, an open-heart operation, and alcohol septal ablation, a catheter procedure.
Septostomy
Septostomy is a catheter procedure that creates or enlarges an opening in a bodily septum, most often the heart's atrial septum, to relieve pressure or improve blood flow.
Sleeve lobectomy
Sleeve lobectomy, also called sleeve resection, is a thoracic operation that removes a lung lobe together with a segment of main bronchus, rejoined end-to-end, mainly for central lung cancer.
Sublobar resection
Sublobar resection is an operation for early-stage non-small-cell lung cancer that removes part of a lung lobe rather than the whole lobe, preserving more lung function.
Substrate ablation
Substrate ablation is a catheter-based strategy for ventricular tachycardia that modifies the scar and border-zone tissue sustaining reentry, developed for VT that is unmappable, noninducible, or hemodynamically intolerable.
Surgical ventricular reconstruction
Surgical ventricular reconstruction (SVR), most often the Dor procedure, is a cardiac operation that reshapes the scarred left ventricle after a heart attack, usually combined with coronary bypass grafting.
Sympathectomy
Sympathectomy is a surgical procedure that interrupts sympathetic nerves to treat primary hyperhidrosis, facial blushing, and selected cardiac or vascular conditions, with Endoscopic Thoracic Sympathectomy (ETS) being the modern standard.
Tetralogy of Fallot repair
Tetralogy of Fallot repair is an open-heart operation that corrects the congenital defect by closing the ventricular septal defect and relieving right ventricular outflow obstruction, routinely performed in infancy since the 1950s.
Thoracic Surgical Procedures
Thoracic surgical procedures (MeSH D019616) are operations on chest organs, most commonly lungs and heart, including CABG, lobectomy, VATS, and robotic approaches.
Thoracoplasty
Thoracoplasty is a chest wall operation in which ribs are resected to shrink the chest, eliminating pleural spaces such as chronic empyema or infected postpneumonectomy cavities.
Thoracoscopic lobectomy
Thoracoscopic lobectomy is minimally invasive surgery that removes an entire lung lobe through small, non-rib-spreading incisions guided by a video camera, used mainly for early-stage non-small cell lung cancer.
Thoracoscopic lung resection
Thoracoscopic lung resection is minimally invasive removal of lung tissue through small incisions without rib spreading, ranging from wedge resection to lobectomy, mainly for lung tumors including early-stage non-small cell lung cancer.
Thoracoscopic thymectomy
Thoracoscopic thymectomy is a minimally invasive operation that removes the thymus gland and surrounding fat through small chest incisions, performed mainly for myasthenia gravis and small thymic tumors.
Thoracostomy
Thoracostomy, including needle thoracostomy, is a clinical procedure that creates an incision or puncture through the chest wall to drain air, fluid, or blood from the pleural space.
Tracheobronchoplasty
Tracheobronchoplasty is a thoracic operation that reinforces the weakened posterior wall of the trachea and main bronchi with mesh, restoring airway shape in adults with severe tracheobronchomalacia.
Tracheoplasty
Tracheoplasty is a surgical reconstruction of the trachea that widens or rebuilds a narrowed airway, most often to correct congenital or acquired tracheal stenosis; slide tracheoplasty trades length for caliber.
Transcatheter aortic valve replacement
Transcatheter aortic valve replacement (TAVR), also called TAVI, is a minimally invasive procedure that implants an aortic valve via catheter to treat severe aortic stenosis.
Transcatheter mitral valve implantation
Transcatheter mitral valve implantation (TMVI), also called transcatheter mitral valve replacement (TMVR), is a minimally invasive catheter procedure replacing the mitral valve, first performed in 2012, for patients unsuitable for surgery.
Transcatheter mitral valve repair
Transcatheter mitral valve repair, also called mitral transcatheter edge-to-edge repair (M-TEER), is a minimally invasive procedure that clips the mitral leaflets together to reduce severe regurgitation without open-heart surgery.
Transcatheter mitral valve replacement
Transcatheter mitral valve replacement (TMVR) is a minimally invasive procedure that implants a prosthetic mitral valve through a catheter, treating severe regurgitation in patients unsuitable for surgery or TEER.
Transcatheter tricuspid valve repair
Transcatheter tricuspid valve repair, or T-TEER, is a catheter-based procedure that clips tricuspid valve leaflets together to reduce severe regurgitation, delivered through a vein without open surgery.
Transmyocardial Laser Revascularization
Transmyocardial laser revascularization (TMLR, transmyocardial revascularization, TMR) is a surgical procedure drilling 10-50 laser channels through the left ventricle to treat refractory angina; FDA-approved in 1998, later judged obsolete.
Transvenous lead extraction
Transvenous lead extraction is a catheter-based procedure that removes pacemaker or defibrillator leads through the veins, mainly for infection, with complete success above 95% and major complications near 1%.
Transvenous pacing
Transvenous pacing is a temporary procedure in which a pacing catheter passed through a vein into the right ventricle delivers electrical impulses to maintain heart rate in bradyarrhythmias.
Tricuspid valve replacement
Tricuspid valve replacement is a cardiac surgery procedure in which a diseased tricuspid valve is replaced with a prosthetic valve, used only when repair is not feasible or has failed.
Uniportal video-assisted thoracic surgery
Uniportal video-assisted thoracic surgery (uniportal VATS) passes a camera and all instruments through one 2.5–5 cm incision, avoiding rib spreading; it was first described in 2004.
Uniportal video-assisted thoracoscopic surgery
Uniportal video-assisted thoracoscopic surgery, or uniportal VATS, is a minimally invasive chest surgery technique in which the camera and all instruments pass through a single small incision.
Valve replacement surgery
Valve replacement surgery replaces a diseased heart valve, most often the aortic valve, with a mechanical or biological prosthesis; the first aortic replacement was reported in 1960.
Valve-sparing aortic root replacement
Valve-sparing aortic root replacement (VSRR) is a cardiac operation that replaces a dilated aortic root with a Dacron graft while preserving the patient's own aortic valve, avoiding a prosthetic one.
