Aortic Valve and the Pulmonary Valve
The aortic valve lies between the heart’s two lower chambers and transports oxygen-rich blood to be distributed throughout the body, while its counterpart, the pulmonary valve, delivers low-oxygen blood to reach lungs instead.
Patients suffering from severe valve disease are treated in a specialist clinic instead of general cardiology clinics to ensure compliance with management guidelines.
Early Life and Education
Waveney Springer, 54, first began experiencing debilitating chest pains without warning while running two businesses – she assumed they were caused by stress but the severe, sporadic pains persisted and she sought medical advice from Thomas Matthew, M.D. of Suburban Hospital’s Johns Hopkins Cardiothoracic Surgery Program Director Thomas Matthew, M.D.
He diagnosed her with a stenotic mitral valve due to scarring from rheumatic fever as a child, performing minimally invasive surgery to replace it and now she’s pain-free and more energetic than ever!
Thomas was not a medical graduate, yet helped white surgeon Alfred Blalock revolutionize cardiac surgery. Their collaboration earned them national renown, winning them both the 1989 National Magazine Award for feature writing as well as an HBO film featuring Mos Def.
Blalock and Thomas continued their partnership when Blalock relocated from Vanderbilt to John Hopkins in 1943, where they engaged in combating Tetralogy of Fallot or Blue Baby Syndrome by opening up the ducts in infant hearts to allow oxygen through. It is widely believed they created this surgical procedure.
Blalock was disgruntled that Thomas was seen as “old hand,” as opposed to one of his “grand old men.” However, Thomas never received promotion or increased pay; thus his salary remained at its original level for many years.
Achievement and Honors
The Aortic Valve (AV) is an integral part of human hearts, controlling blood flow from lungs to left ventricle. If it becomes damaged or defective, causing Aortic Regurgitation Syndrome – leading to serious cardiovascular system issues.
Bob Harper founded a successful sales representative company in New York City that specialized in high-rise commercial building plumbing designs and municipal utility control valve systems. Each year he was awarded with Leonard Valve Co’s prestigious Frederick C. Leonard award.
Chuck was an incredible leader and incredible individual who courageously took risks and invested all of himself without looking back. He leaves behind his beloved wife, children and numerous cherished friends as well as an imprint of generosity and service that continues on into our world today.
Thomas and his brother were never removed from their father’s care despite calls from teachers to Child Protective Services about bruising and hunger; instead, several teachers reported lacerations and urine-soaked garage spaces as possible forms of abuse to CPS hotlines.
Thomas concentrated in later years on research in shock and cardiovascular surgery. Additionally, he participated in creating an innovative heart-lung machine which revolutionized medicine.
Recently, Valve has expanded their efforts in hardware and virtual reality (VR). They introduced Steam Machines along with SteamOS gaming computers in 2015; furthermore they created both HTC Vive and Valve Index VR headsets – although these releases met with mixed reception.
Gabe Newell, as leader of Valve Corporation – creators of games such as Half-Life and Portal – reportedly boasts an estimated net worth of $3 billion. Additionally, Valve offers its digital distribution service Steam as an iTunes-esque service and makes money off each sale that passes through it.
Valve offers value-added services to their customers, such as selection assistance, in-house repairs and maintenance support, technical assistance, training documentation services and technical support. Their team of professionals strive to give each of their customers an optimal experience with Valve products.
Before joining Valve, Ria spent decades working in radio and TV (and still winces whenever someone says, “Let’s go live to!” around her). Today, she works as an accountant at the University of Washington Foster School of Business while also specializing in Localization at Valve.
