Effect of P2Y12 platelet reactivity level on peri- and postoperative outcomes of cardiac surgery patients.

Background: Evidence surrounding P2Y12 platelet reactivity units (PRU) impact on bleeding outcomes in patients undergoing coronary artery bypass is varied. This study sought to assess whether on-pump CABG procedures result in increased bleeding in patients with high compared to low PRUs.

Methods: This retrospective cohort study compared those with a PRU level ≤237 (low PRU group) to >237 (high PRU group).

Patch Repair of an Isolated Right Sinus of Valsalva Aneurysm.

Isolated aneurysm of the sinus of Valsalva is an uncommon problem. It is more likely to occur in the noncoronary or right coronary sinus. Most case reports and series we found in the literature showed that the diagnosis is usually accidental, and surgical repair provides a long-lasting resolution.

Cardiac paraganglioma.

Cardiac paragangliomas are rare tumors arising from chromaffin cells. Two patients with cardiac paragangliomas underwent surgical resection with no evidence of recurrence three and 13 years following surgery. This report describes these two patients with cardiac paragangliomas and discusses their management.
