Acute left atrial dissection during redo mitral valve replacement

Abstract

Left atrial (LA) dissection is an extremely rare and life-threatening complication which is most commonly associated with mitral valve surgery. We report a case of LA dissection after a redo mitral valve replacement and discuss its etiology and management.

Short- and long-term outcomes following redo valvular surgery

“…During redo aortic valve procedures, injuries to the conduction system may necessitate permanent pacemaker implantation. During mitral valve surgery, left atrial dissection and A‐V disruption may occur as well as injuries to the native aortic valve, left circumflex artery, and left ventricular outflow tract . Redo valve surgery may also result in post‐operative myocardial dysfunction because of prolonged aortic cross clamp times.…”

“…During mitral valve surgery, left atrial dissection and A-V disruption may occur as well as injuries to the native aortic valve, left circumflex artery, and left ventricular outflow tract. [28][29][30] Redo valve surgery may also result in post-operative myocardial dysfunction because of prolonged aortic cross clamp times. The use of sutureless valve prostheses may help to expedite these procedures, especially during multi-valve surgery and in those procedures with concomitant coronary artery bypasses.…”

Third time mitral valve replacement-lessons learned

“…Mitral valve replacement may result in unique iatrogenic complications . These risks are increased during re‐operative procedures.…”
