EXHIBIT 99.1 News Release For Immediate Release WorldHeart Announces First Quarter 2005 Financial Results Reports Record Quarterly Revenues Oakland, CA, USA - April 27, 2005: (NASDAQ: WHRT, TSX: WHT) - World Heart Corporation ("WorldHeart" or the "Company"), a global technology leader in mechanical circulatory support systems, today reported its first-quarter results for the period ended March 31, 2005. Summary financial statements are included with this release. WorldHeart's financial statements have been prepared in accordance with generally accepted accounting principles in the United States and are presented in U.S. dollars. 2005 First Quarter Financial Results WorldHeart recorded revenues of $3.4 million in the first quarter of 2005 which is an increase of $1.2 million, or 56%, over the revenues reported in the first quarter of 2004 and a sequential increase of $400,000, or 14%, over the revenues recorded in the previous quarter. This represents record quarterly revenues for WorldHeart and is the third consecutive quarter that revenues have increased. In the first quarter of 2005, WorldHeart recognized revenue on 32 implant kits as compared to 26 implant kits in the same quarter in 2004 and 35 implant kits in the fourth quarter of 2004. Gross margins for the first quarter of 2005 totaled $1.3 million, or 38% of sales. This compares to a gross margin of $1.0 million, or 46% of sales, in the first quarter of 2004. Margins continue to be impacted by variances associated with production levels under capacity and are expected to continue to improve as production volumes increase. The net loss for the first quarter of 2005 was $3.9 million, or $0.24 per share, as compared to a net loss of $3.5 million, or $0.23 per share, in the first quarter of 2004. The net loss of $3.9 million includes non-cash interest charges of approximately $350,000 associated with the accretion of interest associated with WorldHeart's convertible debentures as well as the non-cash amortization of intangibles and non-recurring restructuring costs which together total approximately $250,000. WorldHeart ended the first quarter of 2005 with cash and cash equivalents of $4.5 million. As has been announced previously, WorldHeart has agreed to purchase the assets of MedQuest Products, Inc. ("MedQuest"), which is in the late development stages of a magnetically-levitated, centrifugal flow rotary ventricular assist device ("VAD"), and to complete a $23 million financing transaction consisting of a private placement and the voluntary exercise of existing shareholder warrants. This transaction is subject to WorldHeart shareholder and regulatory approval, which is expected to be received in the second quarter of 2005. RELIANT Trial Update To date, WorldHeart has enrolled fourteen clinical centers and nine patients in the RELIANT trial. Several other centers are well into the process of completing their institutional review processes. "We expect that once twenty centers are enrolled, we will have reached a critical point at which patient enrollment will be more predictable and implants will take place at a higher rate", commented Jal S. Jassawalla, who became WorldHeart President and CEO in July, 2004. Total center enrollment in the study is expected to be between thirty and thirty-five U.S. centers." In April 2005, WorldHeart hosted an international Novacor Users' Meeting and a RELIANT Investigators' Meeting in Philadelphia, preceding the International Society for Heart and Lung Transplantation (ISHLT) Annual Meeting. "We are pleased with the attendance of over 45 clinical centers at our Users' and RELIANT Investigators' Meeting", commented Piet Jansen, MD, WorldHeart's Chief Medical Officer. " There is strong interest in our RELIANT trial which evaluates the Novacor LVAS for Destination Therapy, an important area of clinical need for advanced heart failure patients." ISHLT Annual Meeting In addition, at the ISHLT Meeting, results with the Novacor(R) LVAS were presented by clinical centers in the areas of long-term patient support (exceeding four years), improvements in renal function and improved outcomes with the ePTFE inflow conduit. Product Platform Update "We believe that the mechanical circulatory support market will require both pulsatile and rotary next-generation systems. Pulsatile devices are best suited for end-stage patients with poor ventricular contractility, who require full support or functional "replacement"; rotary devices are better suited for late-stage patients, with some contractility, who require only partial support or assist", commented Mr. Jassawalla. WorldHeart believes that it is the only mechanical circulatory support company with both pulsatile and rotary devices under development. Its current and prospective product platform includes: o The Novacor LVAS pulsatile device which is a leader in terms of reliability and long-term durability and is commercially available as a Bridge-to-Transplant in the US, Canada, the European Union and Japan. In Europe, it is also commercially available for Destination Therapy ("DT") and Bridge-to-Recovery. In the US, it is under evaluation in a pivotal study for DT (RELIANT trial); o The next-generation pulsatile VAD (Novacor II) under development, is a small, bearingless and pulsatile VAD. Development is proceeding as planned, with animal implants expected to begin by year-end; and o The HeartQuest VAD, under development, is a small, next-generation rotary pump currently in preclinical animal and bench testing and is expected to commence initial feasibility clinical trials by the beginning of 2006. "We have made significant progress in each of the last three quarters in three key areas", commented Mr. Jassawalla. "Our sales revenues have increased steadily in each quarter, we have enrolled fourteen centers in the RELIANT Trial, with several others in the pipeline. Finally, with the planned acquisition of MedQuest, we are broadening our product platform to address the full spectrum of clinical needs of end-stage and late-stage heart failure patients. The current Novacor LVAS with its reliability and long-term durability and our next-generation pulsatile, Novacor II, and the acquisition of a rotary VAD system, position us well to serve the growing need for Destination Therapy." WorldHeart will hold a teleconference today at 11:00 a.m. EDT. The teleconference can be accessed domestically by calling 1-800-814-4890 and internationally by calling 416-640-4127.

A replay will be available starting at 2:00 pm (EST) today through Wednesday, May 4, 2005, 11:59 pm (EST) and can be accessed at 877-289-8525 and entering pass code 21122250#. About Novacor(R)LVAS: The Novacor LVAS, a pump implanted alongside the patient's own heart to take over a large portion of the workload of the natural heart, supports end-stage heart failure patients. It is an electrically powered, pulsatile flow device with 20 years of clinical use. The Novacor LVAS has unprecedented reliability and durability. It is the first ventricular assist device to provide a recipient with more than 6 years of circulatory support and continues to hold the industry record for longest support on a single pulsatile device, over 4.75 years. To date, more than 1,600 patients have been supported with the Novacor, with over 600 patient-years of experience and no deaths attributed to device failure. The Novacor LVAS is commercially approved as a bridge to transplantation in the U.S. and Canada. In Europe, the Novacor LVAS has unrestricted approval for use as an alternative to transplantation, a bridge to transplantation, and to support patients who may have an ability to recover the use of their natural heart. In Japan, the device is commercially approved for use in cardiac patients at risk of imminent death from non-reversible left ventricular failure for which there is no alternative except heart transplantation.
