Atrial standstill associated with lamin A/C mutation: A case report

The case report shares evidence for a better understanding of atrial standstill. This being a rare arrhythmogenic condition. This is a 46-year-old woman presented with multiple sites of arterial embolism, including lower extremity arteries, coronary artery, and cerebral artery. Unexpectedly, multiple arterial embolization in the patient was due to atrial standstill by transthoracic echocardiography and cardiac electrophysiological study. An additional family investigation revealed that the patient’s brother and sister also suffered from this disease. In search of further understanding the case, we carried out the genetic testing of the family and a frame shift double-G insertion mutation at c.1567 in the LMNA gene was found in all the three individuals. The patient recovered well after anticoagulation therapy and left bundle branch area pacing. This report remarks on the importance of multiple sites of arterial embolism which should be wary of family atrial standstill.
