Differences between PUS-CNB and surgical resection.

	Dominant position of biopsy	Time consumed (min)	Bleeding volume (ml)	Recovery time of wound	Length of stay in hospital (days)	Effective rate	Limitations
PUS-CNB	Cardiac wall type and pericardial tumor	15.6 ± 3.0	No obvious hemorrhage	The pain disappeared 1 h after the surgery	3	0.875	Potential for bleeding due to limited position of biopsy
Surgical biopsy	All positions	89.5 ± 10.9	210 ± 148.8	Wound healing time (8.8 ± 0.7 days)	12	0.667	Larger wounds lead to slower healing
