What is the most common risk associated with right heart catheterization?

The most common risk associated with right heart catheterization is skin bruising at the insertion site. When a catheter is inserted, the skin and underlying tissues can be disturbed, leading to minor bleeding and bruising. This is a relatively frequent occurrence due to the nature of the procedure and is typically harmless and resolves on its own.

Understanding the risks associated with right heart catheterization provides insight into the importance of patient monitoring during and after the procedure. In contrast, while excessive bleeding, pneumothorax, and air embolism can occur, they are generally less common. Excessive bleeding may occur, particularly in individuals with coagulopathy or on anticoagulation therapy, but it is not as frequently seen as bruising. Pneumothorax, usually associated with procedures on the left side and primarily with central venous catheterizations, is rare with right heart catheterization. Air embolism is a serious complication, but it is an infrequent risk when proper techniques are employed. Therefore, while these risks are significant, skin bruising remains the most commonly encountered complication during right heart catheterization.
