Exhibit 99.1

Sunshine Heart Provides Update on U.S. Pivotal Study of C-Pulse® Heart Assist System

Eden Prairie, MN: April 16, 2015:  Sunshine Heart, Inc. (NASDAQ:SSH) announced today that the U.S. Food and Drug Administration (FDA) has reviewed the Company’s submission regarding the COUNTER HF’s U.S. pivotal study pause and requested minor protocol changes be submitted in order to receive approval to resume patient enrollment. The FDA did not indicate concerns regarding safety of the device and requested the updated protocol include information on several minor items, the most significant of which are the details regarding the Company’s proposal to incorporate a Physician Subject Selection Committee.  Furthermore, the Data Safety Monitoring Board (DSMB), reviewed COUNTER HF’s data and recommended continuing the Study.

“We are pleased the FDA has offered a collaborative process to enable the Study to commence in a timely manner. We were prepared for these types of minor protocol modifications and as such, we’ll be submitting these amendments by early next week,” commented Dave Rosa, President and Chief Executive Officer of Sunshine Heart.

Sunshine Heart previously announced on March 6, 2015, a temporary pause from enrollment in accordance with the study protocol. The protocol indicated that in the event more than three of the first twenty subjects pass away for any reason, including non-device related deaths, the Company would work with the FDA to establish a plan before resuming enrollment. All four of the reported patient deaths have been adjudicated by an independent Clinical Events Committee (CEC) as being non-device related.

COUNTER HF is a prospective, randomized, multi-center, controlled study evaluating the safety and efficacy of the C-Pulse system for the treatment of NYHA Class III and ambulatory Class IV heart failure.  The Study is being conducted by heart failure, electrophysiologists and cardiac surgeon specialists in the United States. It is expected to randomize 388 patients in up to 40 clinical sites. The purpose of the study is to determine whether the C-Pulse System is a safe and effective treatment for heart failure patients who meet the following key study qualifications:

·                  NYHA Class III or early Class IV heart failure*;

·                  Ejection fraction < 35% (measure of how well the heart pumps blood);

·                  Taking appropriate heart failure medications as prescribed by doctor; and

·                  Have been evaluated for cardiac resynchronization therapy with or without defibrillation (CRT, CRT-D) or implantable cardioverter defibrillator (ICD) therapy.

*New York Heart Class (NYHA) Class III or early Class IV: Very limited in daily activities or unable to do activities without discomfort. Become tired, short of breath, and have heart palpitations during physical activity. Note: Other qualifications apply and study doctors will determine who is eligible for the study.

About the C-Pulse® Heart Assist System

The C-Pulse Heart Assist System, or C-Pulse System, an investigational device in the United States, Canada and countries that do not recognize the CE mark approval, utilizes the scientific principles of intra-aortic balloon counter-pulsation applied in an extra-aortic approach to assist the left ventricle by reducing the workload required to pump blood throughout the body, while increasing blood flow to the coronary arteries. Combined, these potential benefits may help sustain the patient’s current condition or, in some cases, reverse the heart failure process, thereby potentially preventing the need for later-stage heart failure devices, such as left ventricular assist devices (LVADs), artificial hearts or transplants. It

may also provide relief from the symptoms of Class III and ambulatory Class IV heart failure and improve quality of life and cardiac function. Based on the results from our feasibility study, we also believe that some patients treated with our C-Pulse System may be able to stop using the device due to sustained improvement in their conditions as a result of the therapy.

Caution: Investigational device, limited by Federal (or United States) Law to Investigational use.
