TopThis is governed by the extent of damage and or symptoms of the patient. What is the usual age at which this stage is reached and surgery becomes necessary? TopThere is no definite relationship with age. Some patients
deteriorate so fast that surgery may become necessary even in' late childhood, while others may enter into their 50s before they require surgery. What investigations are necessary before taking up the patient for surgery? Top Apart from the routine investigations called for at the time of any operative procedure, investigations are carried out for exact determination of the disease. Echocardiography is the best choice. What kinds of valve surgery are currently in vogue? TopIn mitral stenosis, a whole range of surgical techniques is currently being employed. What type of surgery suits which patient depends largely upon the extent of disease and the facilities available. You just said that there are two kinds of valves in use to replace the diseased valve. One, an artificial one, the other, a pig valve. Which is better and why? TopYes, valves are broadly of two kinds. One, made of artificial material, is called a prosthetic valve. The other, the pig valve, is procured from a pig's heart. Are these valves easily available in India? Which kind is more expensive? TopYes, both kinds of valves are easily available in the
country. They are imported from the developed countries. Are prosthetic valves prone to mechanical failure? TopThe risk is very small, almost negligible. If this does happen, a repeat surgery can be done. How long is the usual operating time when a valve has to be mended?Anything between two and four hours. What if it has to be replaced?That usually takes four to five hours operating time. How long is the usual post-operative stay in the hospital after valve surgery? TopCommonly, a patient is discharged from the hospital ten to twelve days after the day of surgery. How much longer does it take for the patient to recuperate and go back to normal life? Often, in about a month or a month-and-a-half the patient can get back to work and resume normal physical activity. What is the operative risk during repair and replacement of valves? TopMending operations have a mortality of less than 2%. But valve replacement surgery has a higher risk of up to 7%. The risk is higher in patients with frank heart failure. What precautions are necessary after valvular surgery? TopPatients must strictly comply with the doctor's advice. Shots of penicillin for prophylaxis against recurrence of rheumatic fever are recommended. Can valve surgery be done on a pregnant patient if necessary? TopYes, if the patient cannot be managed even with intensive medical treatment, surgery may be done. Can a woman fitted with prosthetic valve afford a pregnancy?Yes, but prior advice from the treating doctor must be taken. Such patients need to be admitted to the hospital at least eight weeks before the expected date of labour and their oral anti-coagulant medication dosage needs to be readjusted.
