Chernobyl Heart is a 2003 documentary film by Maryann DeLeo.
 The film won the Best Documentary Short Subject award at The 76th Academy Awards.
Heart failure (HF), often referred to as congestive heart failure (CHF), occurs when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs.
 Signs and symptoms commonly include shortness of breath, excessive tiredness, and leg swelling.
 The shortness of breath is usually worse with exercise, while lying down, and may wake the person at night.
 A limited ability to exercise is also a common feature.
 Chest pain, including angina, does not typically occur due to heart failure.
Varicose veins are veins that have become enlarged and twisted.
 The term commonly refers to the veins on the leg, although varicose veins can occur elsewhere.
 Veins have pairs of leaflet valves to prevent blood from flowing backwards (retrograde flow or venous reflux).
 Leg muscles pump the veins to return blood to the heart (the skeletal-muscle pump), against the effects of gravity.
 When veins become varicose, the leaflets of the valves no longer meet properly, and the valves do not work (valvular incompetence).
 This allows blood to flow backwards and they enlarge even more.
 Varicose veins are most common in the superficial veins of the legs, which are subject to high pressure when standing.
 Besides being a cosmetic problem, varicose veins can be painful, especially when standing.
 Severe long-standing varicose veins can lead to leg swelling, venous eczema, skin thickening (lipodermatosclerosis) and ulceration.
 Although life-threatening complications are uncommon, varicose veins may be confused with deep vein thrombosis, which may be life-threatening.
White Horse is a short documentary by filmmakers Maryann DeLeo and Christophe Bisson that features a man (Maxym Surkov) returning to his Ukraine home for the first time in twenty years.
 Evacuated from the city of Pripyat, Ukraine in 1986 due to the Chernobyl disaster, he has not returned since then.
 DeLeo is the same filmmaker of the 2004 Academy Award-winning short film "Chernobyl Heart".
Foyle Film Festival is an annual film festival based in Derry, Northern Ireland.
 The 21st festival took place from 21 to 29 November 2008 and included the Northern Ireland premiere of "Brideshead Revisited" and the Irish, United Kingdom, and European premiere of Deborah Kampmeier's film "Hounddog".
 Other highlights included anti-nuclear campaigner Adi Roche introducing the documentary "The Children Beyond Chernobyl".
 The Festival included a programme of documentaries, short films and feature films from all over the world, as well as a full programme of educational events.
 Among the later successful filmmakers who exhibited their earliest works at the Foyle Film Festival was actor-producer Stegath James Dorr, who became the then youngest filmmaker to successfully submit a feature film with the Flint-lensed gritty youth docudrama "Dermot", exhibited at the festival in 1995.
 Planning is now underway for the 22nd Foyle Film Festival 2009.
Henning Carlsen (4 June 1927 – 30 May 2014) was a Danish film director, screenwriter, and producer most noted for his documentaries and his contributions to the style of cinéma vérité.
 Carlsen's 1966 social-realistic drama "Hunger" ("Sult") was nominated for the Palme D'Or and won the Bodil Award for Best Danish Film.
 Carlsen also won the Bodil Award the following year for the comedy "People Meet and Sweet Music Fills the Heart".
 Acting as his own producer since 1960, Carlsen has directed more than 25 films, 19 for which he wrote the screenplay.
 In 2006, he received the Golden Swan Lifetime Achievement Award at the Copenhagen International Film Festival.
Charles Wilkinson is a Canadian documentary filmmaker and film and television director.
 He is best known for his "environmental quadrilogy" of documentaries: "Peace Out", "Oil Sands Karaoke" and "" and "Vancouver: No Fixed Address".
 All four films premiered at Hot Docs International Documentary Festival, and have gone on to win awards at Hot Docs, the Vancouver International Film Festival and Yorkton Film Festival.
 Before moving into documentaries, Wilkinson worked for many years in dramatic television series and on feature films.
 His directing credits include such TV series as "", "The Immortal", "So Weird", "Dead Man's Gun", "Road to Avonlea", and "The Beachcombers", the feature films "Max", "Blood Clan", and "Breach of Trust" and the TV movie "Heart of the Storm".
 As a pre-teen, he was one of the original performers in the Calgary Safety Roundup, paired with his brother Billy as kid cowboy singers.
 "We sang both kinds - country and western."
A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.
 In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
 It is used for a non-invasive assessment of the overall health of the heart, including a patient's heart valves and degree of heart muscle contraction (an indicator of the ejection fraction).
 The images are displayed on a monitor for real-time viewing and are also recorded.
