Rupert was first diagnosed with a heart murmur October 2018 . He showed no signs of illness but I was concerned about his rapid breathing. On examination I was told he had a heart murmur and a subsequent X-Ray showed fluid in his lungs and an enlarged heart . We couldn’t believe it as he’d shown no real signs of illness before this . Our cardiologist then determined that he had leakage from the mitral valve and had one episode of heart failure ! He was prescribed Vetmedin, Cardalis and diuretics. These seemed to stabilize him

We rushed her to animal ER where we were told she had congestive heart failure with fluid in her lungs and a severely enlarged heart.
Milo was diagnosed with MVD July 2016. I was told he didn’t need any medication; this was just part of the aging process and his heart was just reflective of his age of 10 plus years. I was told to bring him back in a year. Milo returned to Blue Pearl in August 2017 and the previous Dr. had retired and Milo was assigned to Dr. Mark Harmon. After reviewing his Eco, I was told Milo had advanced stage B2 MVD and probably had
Tiger was diagnosed in March 2018 with a grade IV heart murmur, MVD stage C and severe Pulmonary Hypertension. She was nine years and a half years old.

ToTo is a 10 year old Yorkshire Terrier from New York, NY. ToTo had a totally clean bill of health until a low grade murmur was detected in July of 2016. X-rays and echocardiogram at the time did not conclude treatment, just a follow up one year later. During pre-check for teeth cleaning three weeks ago, March 2017, blood work came back with slightly elevated enzymes in the liver; and x-ray showed a much more enlarged heart than last summer.
Koda’s symptoms came on suddenly and rapidly. He had his yearly check up with his primary care veterinarian in April 2017 with no noticeable murmur whatsoever. Yet in late October 2017 he began coughing consistently, so I took him to be seen by his primary care veterinarian and was referred to a cardiologist immediately.
In July 2014 a level 2 murmur was detected during a routine visit at UF prior to his third dental cleaning and an echocardiogram confirmed Mitral Valve Disease.

Dutch went on Lasix for the fluid in his lungs, enalapril and pimobendan.
In January of 2017 I took Simba in for his annual health check-up and the vet noticed a slightly enlarged heart. I was advised to take him to the cardiologist where I was told everything was fine and that he didn’t need to be on medication at the time. Approximately 1 month after his second cardiologist visit on August 11, 2017, Simba went into congestive heart failure (CHF). A month later, he had another episode and I cried every night reading about this terrible disease.
Bailey is a rescue dog that we adopted in Virginia in 2012. We fell in love with him the second we saw him. His diagnosis with MVD was devastating to us and we wanted to do anything we could to help him. During his annual check up in 2015 he was diagnosed with a heart murmur. Our vet said it was nothing to be concerned with at that time. He was fine until April of 2017 when we found out he had Mitral Valve Disease and his murmur was upgraded to Stage B2. We took him to a cardiologist and he was started on heart medication to try and slow down the disease.
Keisha first presented a stage 2 murmur in April 2017. No treatment was recommended at the time. On 17th December 2017 she was given diagnosis of MVD with CHF and placed on furosemide and spironolactone. Her ultrasound showed very enlarged heart (size of a Doberman) and damaged mitral valve, ruptured chords. After several CHF episodes, surgical options were researched and Jasmine vets in Japan referred Keisha to Niek Beijerink at University of Sydney. Keisha had surgery at University of Sydney with Dr. Uechi on April 19, 2018.
In early December 2017 Dot went into congestive heart failure after 3 years of a mild heart murmur. I found out because he started lifting his nose in the air and refused to lay down. My family and I were all devastated and immediately went to UC Davis's cardiology hospital. We heard about the mitral valve repair surgery for dogs but weren't sure if it was reliable. We were so lucky because we met Dr. Nishimura who knew Dr. Uechi and guided us through the process and introduced me to the Mighty Hearts Project.
During a weekend in September 2017 I noticed Pedey was coughing more and seemed lethargic. I took him to the vet the next day. They performed a chest x-ray and found his heart to be severely enlarged. I thought it looked like a football it was so big. I was able to get him to a cardiologist the following day and he was diagnosed with mitral valve disease and congestive heart failure. He had a grade 4-5/6 left apical systolic murmur and his left atrium and ventricle were both severely enlarged.
Tiara is a 12-year-old Chihuahua. She was diagnosed with MVD on Nov. 2016. Our primary care vet prescribed Apinac 12.5mg for the first half year. In May of 2017, Tiara’s murmur started to get worse, so Dr. Fujisawa added Vetmedin for her. But just after 2 months, she started to cough, and was having difficulties breathing. We brought her to the hospital and they did all the cardiology examinations.
When first learning of Charlie’s diagnosis in July of 2017 I was absolutely devastated. He has been my best friend and constant companion these last 9 years and we have grown inseparable. After many sleepless nights I had stumbled upon the Mighty Hearts page and just like that everything changed! For the first time, since Charlie’s diagnosis, I experienced HOPE!
In March 2017 we discovered that Charlie had a heart murmur when we went to our vets for his annual vaccination and checkup. Following heart scans shortly after we were given the distressing news that Charlie had MVD and that other than managing the disease there was nothing that could be done and we would lose him within 18 months or so. After much research I discovered that surgery may be a possibility and learned about the amazing work of Dr. Masami Uechi. I also discovered that Dr. Dan Brockman at the Royal Veterinary College (RVC) in the UK
Riggs was diagnosed at the age of 5 with the common early onset heart murmur seen in many cavaliers. He was maintained on only Enalapril for 3 years and had echos done every 6 months. He had slowly been having an increase in his heart size but nothing dramatic or that warranted further medication. At the age of 8, Riggs started coughing and having increased respiratory rates. It took several attempts and different veterinarians and specialists to find the right medication combination at that time to help him.
Stella was first diagnosed in November 2016 with a heart murmur by her vet during a routine check up. It was recommended that I take her for an echo just in case. After the echo she was diagnosed with chronic valve disease, so I took her to a cardiologist. At that time she had no symptoms and was not in need of medication. I was told to bring her back every 6 months for re-evaluation. Fortunately, when my cardiologist explained what the disease was and I asked if there was a surgical option, she had heard about the Dr. Uechi and said she would investigate what their protocols where and see if they would look at Stella’s records.
Rusty was first diagnosed with heart murmur grade 3/6 in August of 2016 while traveling and seeing a vet for an unrelated health issue. We were told at the time that heart murmurs are common and that it was unlikely it would progress to anything more serious. In January 2018, Rusty suddenly and with no warning whatsoever started coughing repeatedly. After a quick visit to the ER, he was misdiagnosed with kennel cough and given antibiotics. Two days later with his cough getting much worse, he finally got imaged and was diagnosed with MVD Stage B2 and CHF. We were (once again) traveling at the time and were advised that he may not even survive.
Rocco who is super energetic, was in the garden. I was feeding the birds and he liked to run off with bits of bread as a game. He suddenly started to stumble and look like he was choking. I picked him up and tried to look in his mouth but couldn't see anything. He stopped breathing. I had to think quick as was no time to get to vets.
Sophie is a 9 year old Cavalier King Charles Spaniel from Washington Crossing, PA. Sophie was diagnosed with MVD in June 2012. It was only a grade 2 murmur and did not require any medication at that time. She was rechecked in March 2013 and the MVD had progressed. There was some regurgitation with minimal heart enlargement so she was put on 25 mg Enalapril 2 x per day. Slowly over the following years her heart continued to enlarge

Zoey was originally diagnosed with a heart murmur at four years old and told it wasn't an issue and that the condition would be monitored. After an episode of gasping and coughing in July 2016, Zoey was taken to the vet and misdiagnosed twice with pneumonia and a mass on her lung. She would not have survived the surgery at the time, so Zoey's owners took her to a known ER vet who knew right away it was her heart. She was put on Lasix, put in an oxygen chamber, and referred to a cardiologist at the University of Florida.
In March 2016, Easy was diagnosed with Mitral Valve Disease. She had an enlarged heart which stabilized with drug therapies.
