Repair of a large main pulmonary artery aneurysm in a 71-year-old Jehovah's Witness patient.
Pulmonary artery aneurysm is a rarely reported and poorly studied entity; most mentions in the literature are in case series and case reports. Cardiac surgery in Jehovah's Witness patients is occurring more frequently because of improved techniques of blood conservation. ⋯ The patient recovered rapidly, and her symptoms were greatly improved. We think that a patient's status as a Jehovah's Witness need not preclude potentially life-saving cardiac operations.

We sought to determine whether preoperative statin treatment is more effective in reducing, after cardiac surgery with cardiopulmonary bypass, systemic inflammatory response and myocardial damage markers in patients who have elevated preoperative interleukin-6 levels than in patients who have normal preoperative interleukin-6 levels. The study involved a prospective cohort of 164 patients who underwent coronary and valvular surgery with cardiopulmonary bypass. There were 2 study groups: group A (n = 60), patients with elevated preoperative interleukin-6 levels; and group B (n = 104), patients with normal preoperative interleukin-6 levels. ⋯ Group B1 had significantly lower levels of interleukin-6 than did group B2 postoperatively. There were no significant differences in troponin I levels between groups B1 and B2. We conclude that, in patients with preoperative activation of the inflammatory system, preoperative treatment with statins is associated with lower postoperative interleukin-6 and troponin I levels after cardiac surgery with cardiopulmonary bypass.

Transcatheter aortic valve replacement is an increasingly common treatment of critical aortic stenosis. Many aortic stenosis patients have concomitant left ventricular dysfunction, which can instigate the formation of thrombus resistant to anticoagulation. Recent trials evaluating transcatheter aortic valve replacement have excluded patients with left ventricular thrombus. We present a case in which an 86-year-old man with known left ventricular thrombus underwent successful transcatheter aortic valve replacement under cerebral protection.
