Amiodarone-Induced Pulmonary Toxicity: Percutaneous Needle Aspiration Biopsy and Ultrastructural Findings

Amiodarone, a bi-iodinated benzofuran derivative, is widely used for arrhythmias. Many patients benefit from the effectiveness of amiodarone in treating potentially life-threatening arrhythmias. However, amiodarone-induced pulmonary toxicity (APT) is a severe complication. Even after the discontinuation of amiodarone, not only is APT difficult to manage, but there is also a potentially life-threatening risk of recurrence of arrhythmias. In this case, we describe multiorgan complications secondary to amiodarone use, especially APT combined with pneumonia with atypical pathogens and pulmonary hemorrhage following procedures. Following treatment and stabilization, the patient experienced sudden cardiac death while recovering from pulmonary complications. Case
