Emmy Award winner Catherine O'Hara died on January 30, 2026 at the age of 71 in Los Angeles[1][3][6]. The cause of death was not disclosed[1][2]. The actress suffered from a rare congenital disease of dextrocardia with situs inversus, in which the heart is turned to the right side of the chest and some other organs are located on the opposite side[1][4][7]. She learned about the diagnosis many years ago during an electrocardiographic and X-ray examination during a routine medical examination[1][2]. Most people with situs inversus are unaware of the condition because they do not have symptoms that require treatment[1]. The rescuers were called to her home in a hurry, but even after being taken to the hospital, they could not save her[1].
