Key result
A simulated subxiphoidal puncture directed toward the left midclavicular point with a 30° inclination achieved an 87% success rate and 5% complication rate for blind pericardiocentesis.

Subxiphoid approach to left midclavicular line at 30° yielded highest simulated success (87%) and lowest complications (5%); leaves optimal blind technique open for prospective validation.

Does a subxiphoidal puncture directed toward the left midclavicular point with a 30° inclination improve success and reduce complications compared to other directions in simulated blind pericardiocentesis?
A subxiphoid approach directed to the left midclavicular point with a 30° inclination is the optimal anatomical landmark-guided technique for emergency blind pericardiocentesis, though image guidance remains preferred when available.
Petri et al. (2018) conducted an observational in Moderate to severe pericardial effusions (n=150). Subxiphoidal puncture starting in Larrey's triangle directed toward the left midclavicular point with a 30° inclination vs. Other puncture directions was evaluated on Successful pericardiocentesis (effusion reached). A simulated subxiphoidal puncture directed toward the left midclavicular point with a 30° inclination achieved an 87% success rate and 5% complication rate for blind pericardiocentesis.
