TAH

TAH is an acronym that can refer to several concepts in different fields.

In medicine, the total artificial heart (TAH) is a surgically implanted mechanical device that replaces both ventricles and maintains circulation. It is used to support patients with end-stage heart failure as a bridge to heart transplantation or, in some cases, as destination therapy. The most widely used model is the SynCardia Total Artificial Heart (often referred to as SynCardia TAH). Implantation requires major surgery, postoperative anticoagulation, and ongoing device management and monitoring.

In linguistics, tah is the ISO 639-3 code for the Tahitian language, spoken in Tahiti and nearby islands in French Polynesia. Tahitian is a member of the Polynesian subgroup of the Austronesian language family, and it has a rich oral and written tradition.

Other uses exist in varying contexts, where TAH may stand for different organizations, programs, or terms. Because acronym meanings are context-dependent, there is no single universally recognized interpretation of TAH beyond these or other specific usages.
