Lessons from a case with stiff left atrial syndrome complicated by iatrogenic inter-atrial shunts: a case report.

ABSTRACT:

Background

In patients with stiff left atrial (LA) syndrome, reservoir function is significantly impaired due to extensive LA fibrosis; consequently, the increase in LA pressure during haemodynamic stress is prominent, easily leading to pulmonary venous hypertension and subsequent pulmonary congestion, and eventually results in intractable heart failure.

Case summary

A 79-year-old female with mitral stenosis and atrial fibrillation underwent valve replacement, Cox-Maze IV procedure, LA plication, and appendage ligation 4 years prior to presentation. Thereafter, she underwent a total of two catheter ablation procedures for recurrent atrial tachycardia. Transthoracic echocardiography revealed two continuous colour jets across the interatrial septum, with a peak pressure gradie
