Abstract

A 71-year-old high-risk fourth-time redo male patient was diagnosed with prosthetic valve endocarditis of both aortic and mitral valves, and subsequently required a re-operative aortic and mitral valve replacement. He was placed on cardiopulmonary bypass (CPB) and arrested with normothermic hyperkalemic all-blood cardioplegia (microplegia) containing adjunctive adenosine-lidocaine-magnesium (adenocaine); aerobic arrest was maintained with near-continuous retrograde low potassium (approximately 2 mEq/L) adenocaine microplegia. After 4 hours of arrest on CPB, the aortic valve was found to be incompetent and was resected. A root replacement was required utilizing a Medtronic Freestyle Root prosthesis. Four separate periods of cross-clamp were required during the course of the entire operation. The patient was on CPB for 9.8 hours with a total cross-clamp time of 7 hours, during which he received 72 liters of all-blood adenocaine microplegia. After a terminal "hot shot" with adenocaine microplegia and no added potassium, CPB was discontinued with no systemic hyperkalemia (5.1 mmol/L), no hemodilution (hematocrit, 24%), no balloon pump, no antiarrhythmic agents, and modest inotropic support. The patient was hemodynamically stable, was extubated in 12 hours, and was transferred out of the cardiac ICU after 48 hours with a subsequent uneventful recovery.

Abstract

Objective: Surgical ablation with radiofrequency is a safe and effective treatment for atrial fibrillation. Recent advances in instrumentation have allowed for the application of bipolar radiofrequency through a minimally invasive approach using small bilateral thoracotomies for pulmonary vein isolation, destruction of autonomic ganglia, and excision of the left atrial appendage (GALAXY procedure)., Methods: Thirty-two patients underwent surgical ablation of atrial fibrillation with the GALAXY procedure over a 43-month period. Data were collected in a prospective manner during hospitalization and at 1-, 3-, 6-, and 12-month intervals for rhythm, medications, and subsequent interventions., Results: There were no operative mortality, no myocardial infarction, and no stroke. One patient required reexploration for bleeding. Mean follow-up was 28 months (range, 4-43 months). Freedom from atrial fibrillation at 12 and 24 months, respectively, was 90% and 67% for patients with paroxysmal fibrillation and 80% and 63% for patients with persistent atrial fibrillation. Of the patients who were not in sinus rhythm, four reverted to atrial fibrillation and two reverted to atrial flutter., Conclusions: The GALAXY procedure is a safe and effective, minimally invasive method for treatment of isolated (lone) atrial fibrillation. The operation provides excellent short-term freedom from atrial fibrillation and should be considered in patients with isolated paroxysmal atrial fibrillation.
