Pope Francis, known as “Lolo Kiko” among Filipinos after his 2015 visit, died of a stroke and irreversible heart failure on Easter Monday, April 21.

Vatican doctor Andrea Arcangeli, in a certificate, has confirmed the Catholic leader had a stroke that led him into a coma and heart failure.

The Pontiff, at the age of 88, was hospitalized for 38 days since February this year due to respiratory illnesses and double pneumonia.

Arcangeli declared that the Pope has suffered from a previous episode of acute respiratory failure in the context of bilateral multimicrobial pneumonia, multiple bronchiectasis, hypertension, and diabetes.

All Cardinals in Rome are expected to make funeral plans starting Tuesday, April 22, while the Vatican hopes to conduct the interment between Friday and Sunday this week.

The Pope’s body could be moved into St. Peter’s Basilica by Wednesday, April 23, for public viewing.

In his testament, the Pope wished to be buried outside of Vatican in the Papal Basilica of Saint Mary Major due to his devotion to Mary, Mother of God.

He also desired his tomb to be on the ground as simply as possible, with no ornamentation and only an inscription saying “Franciscus.”

His death set in motion ancient traditions that will commence a gathering of a conclave of cardinals to elect a new Pope.
