A patient experienced episodic pulmonary edema accompanying nocturnal angina pectoris. The symptoms were provoked at cardiac catheterization by atrial pacing. Simultaneous onset of chest pain, shortness of breath, and sudden appearance of a large V wave in the pulmonary artery wedge pressure contour confirmed acute mitral valve regurgitation. Rapid reversal of these changes after nitroglycerin administration supported "papillary muscle dysfunction" as the explanation for these hemodynamic changes.
一名患者出现伴有夜间心绞痛的发作性肺水肿。这些症状在心脏导管插入术时通过心房起搏诱发。胸痛、呼吸急促同时出现，以及肺动脉楔压波形中突然出现大V波，证实了急性二尖瓣反流。硝酸甘油给药后这些变化迅速逆转，支持“乳头肌功能障碍”作为这些血流动力学变化的解释。
