Pope Francis died of a stroke, which led to a coma and ultimately “irreversible cardiocirculatory collapse,’’ the Vatican announced Monday afternoon.

Here’s how Pope Francis’ successor will be chosen:

Dr. Andrea Arcangeli, who is in charge of the health department at the Vatican, disclosed the reason behind the pontiff’s passing. Alongside the cerebral stroke, the 88-year-old pope had pneumonia affecting both of his lungs. This led to instances of respiratory insufficiency, as reported by AP.

Arcangeli also noted that Francis had type-2 diabetes and hypertension.

The pope’s passing came after over two months of back-and-forth hospital visits in Rome. While in the Italian capital, he fought severe respiratory infections. At certain points, he needed high levels of additional oxygen and even had to undergo an emergency blood transfusion during the initial 38-day period at Gemelli Hospital.

He was initially hospitalized with bronchitis Feb. 14.
