Thank you, Scott and good morning, everyone. Welcome to our fourth quarter 2018 earnings call and corporate update. CHF Solutions continues to successfully execute on the strategies we have publicly talked about over the past 12 months. Including one, investing in our direct US sales and clinical teams. Two, expanding our market target areas with new clinical applications for fluid management. Three, growing our international distribution footprint. Four, developing and/or investing in diagnostic technologies to help our customers manage fluid removal. And most importantly number five, increasing revenue growth. I will review each of these strategic initiatives this morning starting with our fourth quarter revenue growth. Fourth quarter revenue was $1.5 million, an 80% increase in year-over-year revenue versus Q4 of 2017 representing seven consecutive quarters of year-over-year double-digit growth. Revenue growth for the year 2018 was 41% compared to the year 2017. Our revenue growth is a result of successful execution of our commercialization strategy and the investment we have made in our direct US sales team and clinical team. We are now fully staffed with 13 US sales territories and 5 clinical education specialists. In January, we promoted one of our experienced account managers to regional manager to join our commercial management team of VP of US sales, Senior Director of Clinical Education and VP of International Business Development. Going forward, we expect modest additional investment in the field organization and will focus on leveraging the investments we have made through 2018. As previously announced, we have expanded our commercial focus into the post cardiovascular surgery market. With the synergies between heart failure cardiologists and cardiovascular surgeons and the treatment of heart day patients suffering from fluid overload, expansion into the post CP surgical market is a natural next step for commercial focus. The cardiovascular surgical market includes procedures such as heart valve replacements, coronary artery bypass grafts, left ventricular assist devices and heart transplants. There are over 7 million cardiovascular surgery per year in the US alone. Cardiovascular surgery patients often need treatment for fluid overload and frequently fail diuretic therapy. Surgical patients can be challenged by fluid overload post procedure due to the extra fluids administered during surgery or medications and medical surgery. Fluid overload accounts for 13.5% of post CB surgery readmissions to the hospital, and is reported as the third most common cause of hospital readmissions within 30 days of surgery. And the number one cause after 30 days post surgery. Excess fluid if not removed effectively contributes to renal dysfunction, arrhythmias and infections and is associated with increased ICU length of stay at a three-fold increase in mortality. The Aquadex FlexFlow system offers a simple form of ultrafiltration that can be prescribed by any medical specialty for the treatment of volume overload in post surgical patients, who are not responding to diuretics. In addition, we have begun discussions with the FDA and preparation for a pre-submission meeting with the FDA. We expect --which we expect to occur in the second quarter of this year. To modify our label to specifically include pediatric patients. We are not currently marketing to the pediatric market, but we are aware that our products are being used to treat pediatric patients. Several children's hospitals use Aquadex to treat pediatrics because of the low volume of extracorporeal blood, only 33 millilitres required in our Aquadex system. These children's hospitals are creating pediatric patients for many conditions that can result with fluid overload including kidney replacement therapy, heart disease, cardiac surgery, extracorporeal membrane oxygenation therapy and organ transplant. We expect 510-K clearance of a specific indication for Pediatrics in the second half of 2019. We look forward to continuing to partner with the medical community in the treatment of fluid-overloaded patients and believe these initiatives create a significant market growth opportunity. We're making progress moving into the heart failure outpatient market, primarily with our clinical partnership with the Tampa VA. As previously disclosed, the United States Department of Veterans Affairs has awarded CHF Solutions Incorporated a five-year, $6.5 million contract to supply Aquadex FlexFlow systems and blood circuits to the James A Haley Department of Veterans' Affairs Medical Center in Tampa, Florida. Both the consoles and the disposables will be utilized for an outpatient physician initiated study focused on improving veterans' quality of life and reducing the cost of hospital admissions by using the Aquadex FlexFlow system in VA outpatient care facilities. There are also several US hospitals providing the Aquadex FlexFlow therapy in their outpatient clinics to avoid a 30-day readmission and the cost and penalties that can be assessed by Medicare. Our international business continues to grow with the fourth quarter negotiations and recent addition of distribution in India and Brazil. In December, Aquadex system was used in a UK hospital to treat a man that had been hospitalized for five weeks due to complications of fluid overload after cardiovascular surgery. During a three-day Aquadex treatment approximately four gallons of fluid was removed and the patient was discharged from the hospital the next day. We are dedicated to providing physicians with solutions that help them more effectively treat fluid-overloaded patients. We remain focused on identifying and researching multiple diagnostic technologies that more clearly inform treatment providers on appropriate Aquadex patient selection, when to initiate therapy, how to manage throughout the therapy and when to discontinue ultrafiltration. We expect to initiate a clinical evaluation with Daxor Corporation soon to document the synergies between the companies Aquadex FlexFlow system and Daxor's BVA-100 blood volume analyzer to assist and informing clinicians on fluid volume status, and how to manage therapy to achieve positive clinical results. We believe that this collaboration with Daxor is another important building block of our strategy to evaluate diagnostic tools which may refine and maximize fluid management therapy. During the fourth quarter, we submitted two new patents to the US Patent Office detailing several enhancements and new features for the Aquadex FlexFlow system. An example includes the ability to significantly strengthen our accutrack bio and penis technology with both central venous pressure measures and systemic vascular resistance measured to accompany our Aquadex FlexFlow system. Given our expanded worldwide commercialization efforts, we anticipate further accelerated sales growth by continuing to position ourselves in the market as the primary provider of ultrafiltration therapy for cardiologists, hospitalists and Intensivist and cardiac surgeons. Our vision is to become the global market leader in fluid management with solutions to improve patient's quality of life. CHF Solutions continues to be at the forefront of fluid management and heart failure when diuretics have failed, spearheading the growing awareness of the current challenges faced with using IV diuretic therapy only, and thereby introducing the clinical value of ultrafiltration treatment as an opportunity to improve clinical outcomes, reduce hospitalization rates and reduce a major expense to the healthcare system. I will now turn the call over to Claudia who can walk you through our Q4 2018 results and financial details. Following that I will provide some closing comments and we'll open the call to questions.
