Dear Sir, My daughter Tripti was born on 3/12/2007,normal delivery.she suffered respiratory distress when she was 4 months old (3/4/2008).she was taken to Victor Apollo GOA, put on ventillator for 9 days and subsequently she recovered and was discharged.she was diagnosed to have severe PAH from her echo report. On followup i was advised to go to heigher center for review. I had taken her to KMC Manipal and later to Narayan Hrudayalaya Bangalore. She underwent echo and CT scan and was started on sildenafil(1/6/2008).After returning from Bangalore,she again had respiratory distress and was again ventillated for 3-4 days.Subsequently after becoming stable she was shifted to Frontier Lifeline Hospital CHENNAI,where she underwent echo,fiberoptic bronchoscopy,barium swallow test,angiogram e.t.c. Finally she was operated by a panel of doctors headed by Dr.K.M.CHERIAN,OPERATION PERFORMED:resection of extra pulmonary sequestrated segment of right lung(at the age of 7 months,22/07/2008). Post operation she improved clinically and her weezing epiosed s which use to occure at an interval of every 2-3 months got reduced. Sildenafil was stopped(20/10/2009) after almost 1.5 year of thearpy as it did not show any benefit as desired by doctor s at Frontier Life Line,Chennai.she was advised for followup after 1 year. she was put on homeopathic medicines from NOVEMBER-2009,and is being treated at Father Muller Hospital,Mangalore.since then till now(last one year and 3 months) she has had no problems of weezing or respiratory distress.She has improved clinically more than what we had expected as parents.She is very active,plays well with other kids,& weighs 10.5 kgs. Echo test was done on 10/01/2011 at Victor Apollo Goa,and the condition has remained same as far as PAH numbers are conserned.we are adviced to consider for Bonsntan thearpy.I am yet to get an opinion from Pediatrician and from Frontier Lifeline Hospital CHENNAI regarding the same. We have been advised to consult a Pediatric Pulmonologist to evaluate cause for PAH,as cardiac wise there is nothing to explain her condition. We are looking up for a Pediatric Pulmonologist to consult. All reports have been attached for your kind perusal. Hoping that every problem has a solution,only we need to look up for solution....... regards, Yashodhan.Heranjal YYYY@YYYY / YYYY@YYYY 08382-254059 0000/0000.
