Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart.
Angioplasty is used to treat venous stenosis affecting dialysis access, with drug-coated balloon angioplasty proving to have better 6 month and 12 month patency than conventional balloon angioplasty. [13] Angioplasty is occasionally used to treat residual subclavian vein stenosis following decompression surgery for thoracic outlet syndrome. [14]
Carotid endarterectomy is used to reduce the risk of strokes caused by carotid artery stenosis over time. Carotid stenosis can either have symptoms (i.e., be symptomatic), or be found by a doctor in the absence of symptoms (asymptomatic) - and the risk-reduction from endarterectomy is greater for symptomatic than asymptomatic patients.
The patient should be able to sit up in bed within 24 hours. After two days, the patient may be moved out of the intensive care unit. Patients are usually discharged after 7–10 days. If the mitral valve replacement is successful, patients can expect their symptoms to improve significantly. [23] Some scarring occurs after surgery.
Aortic stenosis most commonly is the result of calcification of the cusps. Other reasons for stenosis are the bicuspid valve (some patients have only two cusps at the aortic valve instead of the usual three) and rheumatic aortic stenosis (now rare in the West). Obstruction at the level of the aortic valve causes increased pressure within the ...
Severe symptomatic aortic stenosis carries a poor prognosis. At present, there is no treatment via medication, making the timing of aortic valve replacement the most important decision to make for these patients. [4] Until recently, surgical aortic valve replacement was the
