- Doctors say heart surgery on Palestinian leader was successful
- Abbas attended funeral of Israeli statesman Shimon Peres in late September
Abbas, 81, underwent cardiac catheterization, a process in which a tube is inserted into a large blood vessel that leads to the heart.
The procedure is usually performed to find out if a patient has a disease of the heart muscle, valves or coronary arteries, according to the American Heart Association.
The surgery was successful and Abbas is now asleep under sedation, say doctors.
Abbas out and about
One of the last times the Palestinian leader was seen in public was at the funeral of Israeli statesman Shimon Peres in late September. In a brief moment of reconciliation, Abbas shook hands
with Israeli Prime Minister Benjamin Netanyahu.
The two men have often been on opposite sides of a political divide that sometimes seems unbridgeable.
