About This Presentation

Description : Check out this medical PowerPoint presentation titled "Valve Surgery" by V.Rohn.
This medical PowerPoint presentation talks about Valve surgery, a complex procedure that requires skilled surgeons and specialized medical equipment.
Valve surgery refers to a surgical procedure that is performed to repair or replace a heart valve. The heart has four valves - the aortic valve, pulmonary valve, mitral valve, and tricuspid valve. These valves help regulate blood flow through the heart, and any damage or malfunction can lead to serious health problems.

Transcript

Slide 1-

Valve Surgery V.Rohn
Slide 2-

Valve Surgery History before the era of ECC 1925 – Suttar – first successful digital commisurolysis of mitral valve 1952 – Hufnagel – first mechanical „ball and cage“ valve implanted to the descending aorta
Slide 3-

Valve Surgery History With ECC 1960 – Harken – aortic valve replacement with the „ball and cage“ valve 1960 – Starr – replacement of the mitral valve
Slide 4-

Valve Surgery 1962 – Heimbecher – first use of the homograft in the mitral position 1967 – Ross – autograft of pulmonary valve in the aortic position 1971 – Carpentier – introduction of „bioprosthesis“, e.g. xenograft as a valve replacement 1983 – Carpentier –mitral valve plasty (reconstruction) concept
Slide 5-

Stenosis of the aortic valve Indications for surgery symptoms asymptomatic – AVA 0,75cm2/m2 and less pressure gradient 45 – 50mmHg low EF is not a contraindication Procedure Aortic valve replacement

Slide 12-

Aortic valve regurgitation Indication for surgery Symptoms or first signs of LV function deterioration EF < 55 % Dilatation of LV (EDD > 75 mm, ESD > 50 mm) Procedure Replacement Reconstruction

Aortic Valve Repair
Slide 24-

Mitral stenosis Etiology mostly rheumatic Symptoms long time asymptomatic dyspnea embolization (atrial fib.) Indication for surgery valve area less than 0,8 cm2/m2 pressure gradient above 8-10 mmHg
Slide 25-

Mitral stenosis percutaneous balloon valvuloplasty „closed“ commissurotomy „open“ commissurotomy replacement
Slide 26-

Mitral stenosis – open commissurotomy
Slide 27-

Mitral stenosis – closed commissurotomy
Slide 28-

Mitral regurgitation Etiology rheumatic Degenerative mitral regurg. (fibroelastic, myxomatous, Barlow disease) Ischemic symptoms dyspnea a.fib., embolization
Slide 29-

Mitral regurgitation Indication regurgitation more than 2-3/5 (echo, ventriculography) LV dilatation (ESD more than 55 mm) LV dysfunction, EF decrease Procedure 90% of degenerative mitral valves are amenable to repair replacement with preservation of the subvalvular apparatus

Slide 42-

Tricuspid valve
Slide 43-

Etiology Congenital – ASD, VSD, Ebstein disease pacemaker or automatic internal cardiac defibrillation (AICD) wires carcinoid lupus erythematosus, cor pulmonale, inferior myocardial infarction, scleroderma Functional- secondary to cardiac valvular pathology (mostly mitral valve disease) up to 20% of patients undergoing mitral valve replacement receive a tricuspid annuloplasty less than 2% require replacement
Slide 44-

Indication to surgery during left-sided valve surgery when TR annulus is dilated >21 mm/m2; >70 mm intra-operatively; >3.5 cm at TTE Symptomatic stenosis or regurg.
