Recognition and management of left atrial dissection during mitral repair.

BACKGROUND: Left atrial dissection (LAtD) is a rare but potentially life-threatening complication of mitral valve surgery. Its management is not well stablished in the literature. However, early recognition through intraoperative TEE and attention to changes in the left atrial free wall during saline leak testing can lead to avoidance of severe complications. CASE PRESENTATION: We report a case of LAtD detected by intraoperative transesophageal echocardiogram (TEE) following mitral valve repair for primary mitral valve regurgitation secondary to degenerative mitral valve disease with MAZE IV procedure for atrial fibrillation. LAtD was noted on TEE as an expanding double density along the wall of the left atrium with a jet originating at the posterior annulus flowing into the LAtD which was repaired. Separation from bypass following LAtD repair was complicated by severe biventricular dysfunction requiring significant inotropic support and placement of an intra-aortic balloon pump (IABP). Patient's post-operative course was further complicated by right sided heart failure requiring placement of a right sided impella which was subsequently removed on POD 4. Patient was discharged home on POD 17. Transthoracic echo at 1 month, 3 months demonstrated resolution of the LAtD. A follow up echo at 4 years showed complete resolution of the LAtD with an intact mitral repair, trace mitral regurgitation, and a mean gradient across the repair of 3 mm Hg. CONCLUSIONS: Left atrial dissection is a rare but serious complication of mitral valve surgery. We provide a review of the current literature regarding LAtD, emphasizing the need to consider this complication early during mitral surgery to allow for uncomplicated repair.

Use of Ketorolac After Outpatient Urogynecologic Surgery: A Randomized Control Trial.

OBJECTIVE: Patient surveys highlight a prevalence of moderate to severe pain in the postanesthesia care unit. Multimodal analgesia has been promoted to improve this with fewer opioid-induced adverse effects. The aim of this study was to evaluate the opioid sparing and analgesic effect of postoperative intravenous (IV) ketorolac after outpatient transvaginal surgery. METHODS: Forty patients were enrolled in this institutional review board-approved, randomized, double-blind, placebo-controlled study, to receive either 30 mg of IV ketorolac or IV saline placebo postoperatively. Pain was assessed by visual analog scale at timed intervals. Narcotic pain medication was provided upon request. Narcotic use was reassessed by telephone 5 to 7 days postoperatively. Categorical characteristics were compared by χ. Continuous variables were evaluated by Mann-Whitney U test. RESULTS: Twenty patients were randomized to each group. Groups were similar in age, health, and operative factors. There was no significant difference in mean pain scores at any interval. The ketorolac group had a total morphine equivalent consumption median of 7.5 mg versus 4.0 mg for placebo, which was not significant (P = 0.17). Total use of narcotic pills postoperatively was equivalent (median, 5). There was no difference in postoperative nausea. One Dindo grade II complication was reported in the ketorolac group of a postoperative pelvic hematoma requiring transfusion. DISCUSSION: Intravenous ketorolac administered after outpatient transvaginal surgery did not result in a reduction of pain scores or total morphine consumption. There was one Dindo grade II complication in the ketorolac group. Larger randomized control trials are needed to validate these findings.
