Apical complications are considered the "Achilles' heel" of transapical aortic valve implantation, in which laceration and hemorrhage are potentially fatal. We describe the case of a rare complication of the transapical aortic valve implantation procedure, where after apical closure, tension on a distal coronary segment resulted in flow obstruction. Clinicians should be alert to the possibility of distal left anterior descending artery obstruction when ischemia following a transapical procedure is suspected. The exact location of sheath insertion during "transapical" aortic valve implantation is usually apicolateral. A more apical insertion should be avoided since the apex is a relatively weak region and there could be an increased risk of coronary avulsion or apical ventricular septal defect. Nevertheless, a too-lateral insertion could diminish the sheath orientation toward the left ventricular outflow tract and the sheath could also be entrapped with mitral valve chordae. Surgeons should be aware of these factors when deciding on the exact sheath insertion site during tranaspical procedures. |
