Tran­scatheter aor­tic valve re­place­ment (TAVR) of­fers a ray of hope for pa­tients with aor­tic steno­sis. About 50% of pa­tients with aor­tic steno­sis do not sur­vive for more than two years af­ter the on­set of symp­toms un­less treated on time — and only 3% are alive at five years, in­di­cate statis­tics. Aor­tic steno­sis refers to nar­row­ing of the aor­tic valve (main out­flow heart valve). Symp­toms may not be no­tice­able un­til blood flow be­comes sig­nif­i­cantly re­duced. The con­di­tion is con­sid­ered se­vere when blood flow is com­pro­mised to the ex­tent that pa­tients de­velop breath­less­ness, chest pain and un­ex­plained faint­ing or black­outs on ex­er­tion. Over time, the con­di­tion can re­strict the ac­tiv­ity of pa­tients. In some peo­ple, aor­tic steno­sis can oc­cur due to a con­gen­i­tal heart de­fect called a bi­cus­pid aor­tic valve. How­ever, it mostly de­vel­ops dur­ing age­ing as cal­cium or scar­ring dam­ages the valve and re­stricts the amount of blood flow­ing through the valve. 2-D Echo di­ag­noses the dis­ease. TAVR, which an al­ready an estab­lished stan­dard of care for aor­tic steno­sis in Europe and USA, is now emerg­ing as a promis­ing treat­ment in In­dia. A CT scan an­giogram is done be­fore TAVR and is used to size the valve re­quired, as­sess block­ages in the heart ar­ter­ies, and size the leg artery from which the valve can be de­liv­ered. The new valve is po­si­tioned in­side the old dam­aged aor­tic heart valve and starts func­tion­ing im­me­di­ately. The valve has tis­sue leaflets and does not re­quire a strong blood thin­ner as in a metal sur­gi­cal valve. A 65-year-old man from Bangladesh had a se­verely cal­ci­fied aor­tic heart valve. A sec­ond open-heart surgery may have put him at risk. His dis­eased valve was suc­cess­fully re­placed with TAVR, and he was dis­charged within three days and he trav­elled back to Dhaka on day 4. Sim­i­larly, a 150kg gen­tle­man had dif­fi­culty breath­ing and was di­ag­nosed with se­vere aor­tic steno­sis. He al­ready had one open-heart surgery in the past and had a rough course in re­cov­er­ing from it. TAVR was of­fered and he got a dis­charge in four day. To pre­vent aor­tic steno­sis take steps to pre­vent rheumatic fever, take care of your oral health, ad­dress risks of coro­nary artery dis­ease.
