|---|---|---|---|---|
| Mar 2025 | Series E | Ally Bridge Group (lead); Claret Capital Partners; Lumira Ventures; M. H. Carnegie & Co.; Horizon 3 Healthcare; Hostplus | $53M | Cardiac Dimensions, a Kirkland, Washington-based medical device company founded in 2001, develops the Carillon Mitral Contour System, a minimally invasive therapy for functional mitral regurgitation (FMR) associated with heart failure. The device tightens the leaky mitral valve to improve patient outcomes in this high-need population. The company has operations in Sydney and Frankfurt, with about 65 employees, one-third in Europe. On March 20, 2025, Cardiac Dimensions closed an oversubscribed $53 million Series E financing round led by Ally Bridge Group, with participation from new investor Claret Capital Partners and existing investors Hostplus, M.H. Carnegie & Co., Horizon 3 Healthcare, Lumira Ventures, and a confidential strategic investor. The funding will complete the U.S. pivotal EMPOWER Trial and support global commercial expansion of the Carillon therapy outside the U.S. CEO Rick Wypych emphasized the company's positioning to provide a safe, simple, and effective solution for FMR patients, noting the investors' strong conviction in the therapy's potential. Steve Plachtyna of Ally Bridge Group, now on the board, highlighted progress in clinical efforts and commercial sales. Total funding raised by the company exceeds $200 million, with estimates around $214.76 million to $267.76 million across 17 rounds. |
| Jan 2023 | Series D | Horizon 3 (lead); Lumira Ventures; Redbus Ventures; M. H. Carnegie & Co.; Arboretum Ventures; Hostplus | $35M | Cardiac Dimensions, a Kirkland, Washington–based medical device company, develops minimally invasive treatments for heart failure and functional mitral regurgitation (FMR). The company's Carillon Mitral Contour System is designed to tighten a leaky mitral valve through a catheter-based procedure, addressing a condition where blood leaks backward through the heart's mitral valve during left ventricular contraction. The system has completed four clinical trials investigating safety and performance, with a fully randomized, blinded, sham-controlled trial among the completed studies. Cardiac Dimensions closed a Series D financing round in January 2023, raising $35 million to advance clinical development and commercialization efforts. The company had previously raised $39 million in Series B funding in April 2018. By March 2025, the company had closed a subsequent Series E round of $53 million, bringing total disclosed funding to approximately $214.76 million. The Carillon Mitral Contour System has received regulatory approval in Europe and is available in countries that recognize European medical device standards. In the United States and Canada, the device remains investigational and is available only for research purposes. The company is conducting the EMPOWER Trial, a pivotal U.S. study designed to support regulatory approval in the American market. As of 2025, Cardiac Dimensions operates offices in Kirkland, Sydney, and Frankfurt, reflecting its global commercialization strategy focused on expanding access to mitral valve therapies for heart failure patients. |
| Sep 2020 | Series C | EQT; Aperture Venture Partners; Lumira Ventures; Redbus Ventures; M. H. Carnegie & Co.; Arboretum Ventures; Hostplus | $18M | Cardiac Dimensions closed a $17.5 million Series C financing on September 29, 2020, led by existing shareholders including Aperture Venture Partners, Arboretum Ventures, Hostplus, Life Sciences Partners, Lumira Ventures, and M.H. Carnegie & Co. The company develops the Carillon Mitral Contour System, a minimally invasive device designed to treat functional mitral regurgitation (FMR) in patients with heart failure by tightening the leaky mitral valve through a catheter-based procedure. The round followed regulatory approval from Australia's Therapeutic Goods Administration earlier in September 2020 and was intended to accelerate commercial sales expansion in Europe and new geographies including Australia. At the time of the round, the Carillon System had completed clinical trials and demonstrated safety and efficacy in treating a large patient population with limited therapeutic options. The company later raised a $53 million Series E round in March 2025, bringing total disclosed funding to over $200 million, and continued advancing its EMPOWER Trial U.S. pivotal study while expanding global commercial operations. |
| Apr 2018 | Series B | Hostplus (lead); Aperture Venture Partners; Lumira Ventures; M. H. Carnegie & Co.; Arboretum Ventures; Oxford Finance LLC; LSP Health Economics Fund | $39M | Cardiac Dimensions, a developer of minimally invasive treatments for heart failure, particularly functional mitral regurgitation (FMR), closed a $39 million Series B financing in April 2018 led by Australia-based Hostplus with participation from venture debt provider Oxford Finance LLC and existing investors M.H. Carnegie & Co., Arboretum Ventures, Lumira Capital, LSP Health Economics Fund, and Aperture Venture Partners. The company's flagship product is the Carillon Mitral Contour System, a catheter-based alternative to medications and invasive surgery for treating FMR in heart failure patients. According to Hostplus leadership, an estimated 50,000 Australians and hundreds of thousands globally have heart failure with FMR and could benefit from the Carillon System. The funding was intended to support completion and publication of the landmark REDUCE FMR trial, continue enrollment in the U.S. CARILLON pivotal trial, and enhance the company's presence in world markets. Cardiac Dimensions went on to raise a $17.5 million Series C in September 2020, a $35 million Series D in January 2023, and a $53 million Series E in March 2025, demonstrating continued investor confidence in the Carillon therapy's commercial and clinical potential. |
| Mar 2015 | Series A | EQT; Aperture Venture Partners; Lumira Ventures; Difference Capital; M. H. Carnegie & Co.; Arboretum Ventures | $15M | Cardiac Dimensions completed a $43 million equity financing round announced around November 2015, with the addition of $15.2 million from investors including Aperture Venture Partners, Life Sciences Partners, Lumira Capital, M.H. Carnegie & Co., and Arboretum Ventures. The proceeds supported the REDUCE FMR clinical trial, a blinded randomized study of the Carillon Mitral Contour System for functional mitral regurgitation in heart failure patients across up to 20 hospitals in Europe and Australia, as well as R&D and commercial expansion. |
| Oct 2014 | Series A | Arboretum Ventures (lead); Lumira Ventures | $9M | Cardiac Dimensions, a Kirkland, WA-based developer of the CARILLON Mitral Contour System for treating functional mitral regurgitation in heart failure patients, expanded its equity financing to $28.5 million in October 2014 with an $8.5 million addition led by Arboretum Ventures, joining Lumira Capital, M.H. Carnegie & Co., and other international investors. The round followed an initial $20 million tranche closed in April 2014. Proceeds supported completion of the REDUCE FMR clinical trial, the company's first blinded, randomized multi-center study evaluating the percutaneous mitral repair device, and expanded commercial efforts following positive TITAN II trial data. This financing built on prior rounds, enabling aggressive pursuit of clinical, commercial, and geographical objectives for the minimally invasive therapy targeting the 70% of 20 million heart failure patients with functional mitral regurgitation. |
| Apr 2014 | Series A | Lumira Ventures (lead); M. H. Carnegie & Co. (lead); Redbus Ventures | $20M | Cardiac Dimensions is a Kirkland-based medical device company founded in 2001 that develops minimally invasive treatments for heart failure and functional mitral regurgitation (FMR). The company's flagship product is the Carillon Mitral Contour System, a non-surgical catheter-based device designed to treat mitral valve regurgitation, the most common type of heart valve disorder affecting approximately 70 percent of the 20 million people suffering from FMR. In April 2014, Cardiac Dimensions closed a $20 million financing round led by M. H. Carnegie & Co. and Lumira Capital.
