This page provides all possible meanings and translations of the word cardia
the opening into the stomach and that part of the stomach connected to the esophagus
a former town in Thrace
The section of the esophagus that connects to the stomach.
Origin: From καρδία.
the anterior or cardiac orifice of the stomach, where the esophagus enters it
Origin: [NL., fr. Gr. heart, or upper orifice of the stomach.]
The cardia is the anatomical term for the part of the stomach attached to the esophagus. The cardia begins immediately distal to the z-line of the gastroesophageal junction, where the squamous epithelium of the esophagus gives way to the columnar epithelium of the gastrointestinal tract. Near the cardia at the gastroesophageal junction is the anatomically indistinct but physiologically demonstrable lower esophageal sphincter. The area termed the cardia overlaps with the lower esophageal sphincter; however, the cardia does not contain the lower esophageal sphincter. Although the topic was previously disputed, current consensus states that the cardia is part of the stomach. The cardia overlaps with but specifically does not contain the lower esophageal sphincter. This is in contrast to the "upper esophageal sphincter" contained in the hypopharynx and consists of striated muscle controlled by somatic innervation. The z-line is usually within the LES, thus LES can be identified by z-line color that changes from salmon pink to a deeper red. But, a study correlating manometric and endoscopic localization of the LES found that the functional location of LES was 3 cm distal to the z-line.

That part of the STOMACH close to the opening from ESOPHAGUS into the stomach (cardiac orifice), the ESOPHAGOGASTRIC JUNCTION. The cardia is so named because of its closeness to the HEART. Cardia is characterized by the lack of acid-forming cells (GASTRIC PARIETAL CELLS).
Incorporated in 1998, Cardia, Inc. is an innovative company engaged in developing, manufacturing and marketing transcatheter septal occluders. To date we have closed over 15,000 septal defects worldwide.Ultrasept, our latest family of products, serves as our 7th generation of septal closure devices. The dual articulating sails allow for easy deployment of the devices and create a super low profile within the atria. Ultrasept devices boast a simple, hands-free loading feature and are fully retrievable before and after release. Ultrasept products include double-round devices for the percutaneous closure of both PFO's (Patent Foramen Ovale) and ASD's (Atrial Septal Defect).A septal occluder is a cardiac implant that fixes a cardiac defect commonly referred to as a "hole in the heart.” Our devices are delivered through a catheter by an interventional cardiologist and only take about 30 minutes to implant. Many patients are admitted to the hospital in the morning and return home that afternoon or the next day without the lengthy recovery periods often needed after open-heart surgery.The market for our septal occluder products revolves around the need to close or fix a number of both pediatric and adult cardiac defects. The PFO (Patent Foramen Ovale) defect appears to occur in approximately 25% of the adult population. Most people have no symptoms and therefore require no treatment; however, it is now believed that about 250,000-1,000,000 cases worldwide per year may require closure. These people initially experience a cryptogenic stroke and upon follow up with their neurologist are revealed to have a PFO defect. If the defect is not closed, these patients are subject to repeated strokes.Similarly, ASD's (Atrial Septal Defect) appear in approximately 100,000-150,000 cases per year worldwide. Over time, if the defect is left unrepaired, serious cardiac problems can arise.Another possible application for the Ultrasept PFO devices is with regards to the relationship between PFO's and migraine headaches. Presently it is known that approximately 50% of all migraine sufferers have a PFO. Clinical Studies are currently underway to confirm this relationship of PFO's and migraine headaches.
