TAVR is a young heart valve replacing treatment . The full term TAVR means transcatheter aortic valve replacing , in this process a thin thread cognize as catheters is inserted through the artery of leg to bosom . Valve made from animal tissue paper is position in the heart part ; this approach is jazz as aortal stricture . This narrowing appendage in reality helps in deflect many complicated things like dresser initiative , use of heart - lung ringway simple machine or making any incision in heart . Earlier , before TAVR amount in to visualise open heart operating theater was the only fashion of intervention for grievous stenosis .
High-Risk Patients
Majority of people are not recommended to undergo valve replacement surgery . This is so because either they are not physically fit to undergo the surgery or they may spring up any other serious after surgery ramification . For such citizenry , transcatheter aortal valve replacement is no where less than a life-time saving intervention process .
Moderate-Risk Patients
Transcatheter aortal valve replacement has also received approval from FDA i.e. , Food and Drug Administration for execute this treatment on those affected role who have moderate surgical risk . TAVR help oneself in following ways :
Is TAVR Safe?
permit us take a feeling on how safe and in effect TVAR treatment is . In the past tenner , massive organic evolution has taken shoes in the field of operative technique for produce the heart surgical operation more effective and safe in every respectfulness . Earlier , for aortic valve surgery doctor habit to make a deep slit in the breast of the patient and then the patient was kept on middle - lung simple machine . Despite of the fact , how dependable the handling is there was no other treatment option available to doctors . As overt ticker surgery has a lot of peril associated , so it is not recommended to elderly multitude or who put up from weak marrow condition . However , if we talk about TVAR i.e. transcatheter aortal valve replacement engineering , it does not require to keep the patient on heart - lung machine or making any surgical incision on patient ’s chest . This come about because TAVR technique is performed with the help of a hunky-dory catheter , which is insert into the patient organic structure through peel . TAVR is far less dreadful liken to open heart operating theater . Hence , the patient who were not advocate to undergo open philia can undergo TAVR intervention because the risk imply in the process is less and the success rate of the procedure is also very high .
How It Works?
In traditional unfastened heart surgery , doctors remove the old valve and place Modern valve . However , in TAVR technique the Modern valve is placed properly inside the previous or existing one . This is done in such a way that the new valve move indoors by mash the old valve . As the procedure is done with the help of a fragile tube ; so the artificial valve is compressed before it is inserted into the torso . Once the valve is successfully place in the right position , the valve is then expanded to its original size .
establish on how the valve is expanded , there are two case of TAVR valves , one is balloon expansible and the other one is the self expandable . In the balloon expansile one , the compressed valve is expanded using balloon . Once the valve reaches its required location , the balloons inflates on its own flesh out the valve to its original size . On the other hand self expansile type of valve has a squeeze springtime inside the tube . Once the self expansible TAVR valve reach its place , the valve expands naturally .
