The Value of Right Heart Catheterization

Although the right heart catheterization (RHC) was first introduced in 1945, its use in the quantitative hemodynamic assessment of patients has remained of questionable benefit. With recent advances in pharmacotherapies and mechanical support devices, RHC has been increasingly used to assess and help tailor the management of more complex patient scenarios. We present a case series in which the use of the RHC was helpful in making complex medical decisions. (Level of Difficulty: Intermediate.)
