You answered incorrectly.
The correct answer is (d) inflate balloon proximal to the area of perforation to limit bleeding. If a small leak, it may tamponade, but at least limiting leakage will provide stability for the patient to decide next steps. One will likely not stop anticoagulation immediately given the devices in place and the status of stents etc. so (a) is not the appropriate initial option. While, occasional perforations require surgery, most can be handled in the cath lab and therefore calling surgery is not the first choice. Thus, (b) is not the best first choice. Likewise preparing for a ping-pong technique is not the best first step, making (c) incorrect. Lastly, pericardiocentesis is not the first step (e) and is not correct. Controlling the bleeding precedes all of the others.
