Left ventricular puncture during thoracentesis.

Left ventricular puncture during a thoracentesis is a rare and unusual complication that has yet to be reported. We report a case in which a 74-year-old woman with dilated ischaemic heart disease suffered from puncture of the left ventricle during a routine ultrasound-guided thoracentesis despite following the recommended protocol and procedures. She became haemodynamically unstable and underwent an emergent thoracotomy for removal of the catheter and repair of the left ventricular wall. © BMJ Publishing Group Limited 2019.
