Save Lily's Heart

Hello Everyone!
Let me start off by telling you a little bit about myself. I am Mariana Pardo, I am a veterinarian currently in my 2nd year of my Emergency and Critical Residency at Cornell. 8 years ago I came to the states from chile to pursue my specialty. during this entire time I avoided getting a pet as I was "too busy" to take care of them.
The reality is that the right one hadn't appeared....
It was my day off when I received a text message with a picture of the most precious puppy ever. The text message said "she needs a home"...
For those that don't know me, I had miniature schnauzers growing up, so they hold a special place in my heart. Working in a vet school I have seen my fair share of cuteness needing a home and have always been able to walk away. But not this time. Nothing else but love at first sight could explain what I felt. I met her 15 minutes later and could not perceive a life without her. Of course, there was a catch.
She was being given away because she had pulmonic stenosis (a congenital heart defect that involves a narrowing of the valve  going from theright ventricle into the pulmonary artery). She was 15 weeks old, but I was assured that she may never require surgery and maybe not even medications. I took her without hesitation and she became a blessing in my hectic world.
A few months later she had a syncope (fainting episode) and she had another echocardiogram. They unfortunately found that she in fact had double chamber right ventricle ( congenital anomaly in which the right ventricle is divided into 2 portions by abnormal muscle bundles). Her heart had been too small previously to observe this.
The prognosis is grave and her life expectancy can range from 6 months to 2-3 years at most, she could go into heart failure at any time. In order to slow down her progression she was started on atenolol, a medication that slows her heart down. She recently had another echocardiogram and her heart has worsened despite medications.
The amazing cardiologists at Cornell now recommend surgery. This involves placing a catheter through her jugular vein into her heart, the tip of the catheter has a balloon and cutting blades, when the balloon is inflated the blades cut through the muscles that are producing the double chamber. This is a high risk surgery that is rarely done in animals, her chances of mortality during surgery are 50/50, however it is her only chance.
As a resident, the costs of a procedure like this are beyond what I can afford, and so I ask all of you to help me raise enough money to cover for the expenses of Lily's surgery.
If this is her best chance, I want to do everything in my power to make her better. What ever time I have with her will be a blessing and I will never regret taking her because she has given me so much more than I could ever give her back.
