Nechama Rivlin, the wife of Israeli President Reuven Rivlin, was rushed to the hospital on Tuesday evening after experiencing heart complications more than a few weeks after receiving a lung transplant.

Rivlin, 73, was suffering from a “severe shortness of breath with a cardiac link,” according to a statement from Beilinson Hospital in Petach Tikvah, where the operation occurred and where she is currently hospitalized.

The hospital said she has been sedated and is on respiratory support.

Her husband, who is 79, cut short his trip to Canada and is scheduled to be on the next Air Canada flight home, which departs around midnight Israel time and will land in Israel at 9 a.m. local time, reported The Times of Israel.
