Fatal visceral ischemia as a complication of intra-aortic balloon placement.

We present a case of visceral ischemia due to an anatomic versus balloon length mismatch. An 80-year-old women underwent elective coronary artery bypass graft surgery. The direct post-operative period was complicated by low cardiac output, not responding to inotropic or vasopressor drugs. An intra-aortic balloon pump (IABP) was inserted during an explorative rethoracotomy. The first 3 days, an improvement of the hemodynamic function was seen. During this period, hepatic dysfunction, renal failure with need for hemodialysis and rising values of serum lactate were seen. A computed tomography (CT) of the chest and abdomen showed splenic infarction, ascites and signs of gastric and intestinal ischemia. The IABP was blocking the celiac trunk, the superior mesenteric artery and the renal arteries and was immediately removed. The patient died shortly after due to multiple organ failure. To prevent ischemic complications in smaller patients, we advise a follow-up CT after placement of the IABP.

Mid-term follow-up after maze IV procedures for concomitant atrial fibrillation.

BACKGROUND: We performed a retrospective analysis of the maze IV procedures performed in our surgical department for concomitant atrial fibrillation. METHODS: Preoperative, in-hospital and postoperative follow-up data were collected from 46 consecutive patients who underwent the maze IV operation between April 2006 and December 2010. All electrocardiograms and Holters were reviewed. RESULTS: One patient died in-hospital. During a mean follow-up of 25 +/- 16.3 months seven patients died: two related to a hemorrhagic stroke, one due to right ventricular failure, the remainder deaths were not cardiac related. The success rate, defined as no recurrence of AF or atrial flutter with a blanking period of 6 months postoperatively, was 73.7%. Plots of probability of freedom of atrial fibrillation over time are drawn and reach a stable level after one year. CONCLUSIONS: The mid term results of the maze IV procedures for concomitant atrial fibrillation are very good. The results are stable for the remainder of follow-up.

[Favourable long-term results using the unmodified maze procedure in patients with medication-refractory or nearly refractory atrial fibrillation; experience from 1993/'04]. / Gunstige langetermijnresultaten van de originele 'maze'-operatie voor patiënten met medicamenteus moeilijk of niet te behandelen boezemfibrilleren; ervaringen van 1993/'04.

OBJECTIVE: To assess the short- and long-term results following the unmodified maze procedure in patients with medication-refractory or nearly refractory atrial fibrillation. DESIGN: Retrospective. METHODS: We retrospectively collected and analysed preoperatively in-hospital and follow-up data from patients with atrial fibrillation with or without structural heart disease who underwent the unmodified maze procedure in the St. Antonius hospital, Nieuwegein, the Netherlands. RESULTS: In the 11-year period 1993-2004, 203 patients underwent the procedure: 139 underwent the maze procedure only and 64 underwent combined surgery for concomitant atrial fibrillation and structural heart disease. There were no in-hospital deaths. During a mean follow-up period of 4 years, 2 ofthe 203 patients died from cardiac causes; both had undergone combined surgery. With a mean follow-up period of 4 years, the rate of atrial fibrillation-free survival was 90% in patients with lone atrial fibrillation and 70% in patients with concomitant atrial fibrillation. For patients who had no recurrent atrial fibrillation 1 year after surgery, the risk of recurrence after 4 years was small (odds ratio: 9.56). Risk factors for recurrence included a large left atrium and a long duration of atrial fibrillation (more than 5 years). CONCLUSION: The maze procedure was a successful surgical intervention for patients with atrial fibrillation, both in the short and long term. This procedure can be considered when medication and electrical cardioversion are ineffective.
