Suffering from congenital heart disease, Ching Ching has undergone multiple heart surgeries and is currently in critical condition in the Pediatric Intensive Care Unit due to heart failure and pulmonary hypertension. She is currently at the top of the waiting list for heart and lung transplants among patients of her body size and urgently requires a suitable organ donor.
