Board Certified In Phlebology

3231 South Higuera Street

Premier Heart and Vein Care successfully marries the concept of small town care and high-tech health care in this practice were “ahead of the curve” meets style, sophistication, and service. Dr. Kenneth Stevens and his staff pride themselves on a comprehensive and holistic approach to providing the latest in medical technology to care for the unique inter-relationship between coronary, arterial, and venous disease.  

Premier Heart and Vein Care features the most innovative and advanced equipment on the Central Coast in San Luis Obispo. Premier Heart Care and Vein Care were established in 2008 and 2010 respectively, with the practices now combined together.  In addition to providing cardiovascular care, the practice offers Covidien ClosureFAST Radiofrequency Ablation (also known as the Venefit procedure) and both sclerotherapy and laser treatment to patients suffering from venous insufficiency, varicose veins and spider veins. The in office ultrasound lab used to evaluate patients has been certified for quality by the American College of Radiology as well.  Dr. Stevens' practice is located on the Central Coast in San Luis Obispo and provides radiofrequency ablation as an in-office service to those in the region suffering from varicose and spider vein issues. 

Radiofrequency Vein Ablation is a same-day treatment that is virtually painless, treats the underlying pathology, minimally invasive, and gets you right back on your feet better than ever. Dr Stevens has been involved with teaching other physicians about phlebology and the radiofrequency ablation procedure; he has performed over 2300 ablation procedures and almost 5000 venous ultrasounds. He  has developed a high quality practice with patients travelling from as far away as Monterey, Bakersfield, Santa Barbara, Santa Maria and Los Angeles suburbs, as well as locally for care. Lastly, the practice has now incorporated the Venaseal procedure into the practice, which involves treating varicose veins with a special FDA approved glue compared with using thermal energy or chemicals to close a pathologic vein, along with the Cutera Xeo laser platform to treat spider veins and reticular veins.

Services Offered

Venous Duplex Scanning: A venous duplex scan uses sound waves to assess the function of the veins. This exam assess all of the veins in the leg, both superficial and deep, from the groin to the ankle. During the exam, both legs will be examined. The test also helps to detect a blockage in blood flow (such as a blood clot) that may cause pain or swelling in the legs. The test measures any venous reflux that may occur, and helps generate a treatment roadmap. Our lab is certified by the American College of Radiology. 

The Covidien Closure Fast or Venefit  procedure is a minimally invasive treatment alternative with less pain and less bruising when compared to traditional vein stripping surgery and laser treatment. Using the Closure Fast system, Dr Stevens closes the diseased veins by inserting the Closure Fast catheter into a vein and heating the vein wall using temperature-controlled radiofrequency energy. Heating the vein wall causes collagen in the wall to shrink and the vein to close. After the vein is sealed shut, blood then naturally reroutes to healthy veins. Radiofrequency ablation has been utilized for over ten years, in over 500,000 patients, with success rates greater than 90%. 

Sclerotherapy involves the direct injection of an FDA approved sclerosing agent into the varicose vein using either a very fine needle or catheter. This chemical solution irritates the vein tissue, and causes the vein to close. The practice offer both foam and liquid sclerotherapy, and is one of just a  few centers in California offering Varithena
                                                                                                                                                                                                                                                  Wound care and lymphedema treatment:   At times, patients with venous disease have more severe conditions such as non healing ulcers and lymphedema. The practice does have experience in dealing with these challenging patients; often, these have been long standing problems. Evaluation entails  a comprehensive approach assessing the heart, arteries and as well the veins to guide proper management and treatment. Dr. Stevens" background and training allows him to successfully address these complex cases. His is the only practice in the region using Apligraf to treat venous ulcers.

He holds a B.A. degree from Colgate University, M.S. degrees from Georgetown University and University of Wisconsin–Madison, and a Medical Degree from Loyola University of Chicago.

Dr. Stevens eventually relocated to San Luis Obispo, California, where he opened Premier Heart Care in 2008. At Premier Heart Care, Dr. Stevens is committed to treating patients with the utmost respect and compassion. Delivering the highest standard of cardiac and vascular care is his top priority, and his practice has built a strong reputation for providing state-of-the-art diagnosis, disease management, and treatment.

After many years of interest, Dr. Stevens decided to offer non-surgical treatment for varicose veins and venous insufficiency in addition to cardiovascular treatment. It was then that Premier Vein Care was born in 2010, allowing for a more comprehensive approach to vascular care. At Premier Vein Care, patients  receive high quality vein treatment in a friendly, state-of-the-art facility. The ultrasound lab is certified by the American College of Radiology, and Dr. Stevens is a registered phlebology sonographer, RPhS, through Cardiovascular Credentialing International.
