A Case of Cardiogenic Stroke After Thoracoscopic Left Atrial Appendectomy.

Thoracoscopic left atrial appendectomy is a minimally invasive procedure for left atrial appendage occlusion in patients with non-valvular atrial fibrillation, particularly those at a great risk for both stroke and bleeding despite appropriate oral anticoagulant therapy. It serves as an alternative strategy for stroke risk reduction. Moreover, the oral anticoagulant therapy can be discontinued after the operation. However, we encountered a 74-year old male patient who developed cardiogenic stroke after thoracoscopic left atrial appendectomy. We report this case to introduce how we evaluate the risk of postoperative cardiogenic stroke by means of contrast-enhanced cardiac computed tomography (CT), and how we formulate the postoperative patient management strategy including short-term oral anticoagulation therapy by using results of cardiac CT.

Thoracoscopic left atrial appendectomy and thoracic endovascular aortic repair (TEVAR) in a patient with cardiogenic stroke combined with acute aortic dissection.

The simultaneous occurrence of cardiogenic stroke and acute aortic dissection is rare, and its treatment remains unclear. Although anticoagulation therapy is usually chosen for cardiogenic stroke due to atrial fibrillation, it is inappropriate for acute aortic dissection. Recently, thoracoscopic left atrial appendectomy (TLAA) has been suggested as an alternative for anticoagulation. We herein report a case of a 78-year-old man with combined cardiogenic stroke and acute aortic dissection in whom thoracic endovascular aortic repair (TEVAR) was performed after TLAA. Although anticoagulants were discontinued after TLAA, there was no recurrence of stroke, and he underwent TEVAR safely. This case indicates that TLAA followed by TEVAR is an ideal treatment for combined cardiogenic stroke and acute aortic dissection and also suggests a new indication of TLAA.

[Relapse of Mitral Regurgitation Due to Tethering after Valve Plasty with Edge-to-edge Repair;Report of a Case].

A 75-year-old woman with severe mitral regurgitation (MR) successfully underwent mitral valve plasty with edge-to-edge plasty and commissural annuloplasty. Three days after the operation, she was found to have moderate MR caused by tethering of the valve. Functional MR occurring as a complication of mitral edge-to-edge plasty could be treated conservatively.

[Thoracoscopic Left Atrial Appendectomy for a Patient with Thrombus in the Left Atrial Appendage after Anticoagulation Therapy;Report of a Case].

Thoracoscopic left atrial appendectomy for patients with non-valvular atrial fibrillation has been suggested as a new approach for preventing cardiogenic thromboembolism. While this procedure is effective in patients who suffer from thromboembolism even with anticoagulation therapy, it is contraindicated in patients with an existing left atrial appendage thrombus. We herein report a case of 61-yearold female with atrial fibrillation and recurrent cardiogenic thromboembolism. Left atrial appendage thrombus had been detected even under anticoagulation therapy. We decided to strengthen anticoagulation therapy and successfully resolved the left atrial appendage thrombus. Thus, thoracoscopic left atrial appendectomy was performed safely, and thromboembolism has never occurred since the operation.

Efficacy of vacuum-assisted closure therapy on rehabilitation during the treatment for surgical site infection after cardiovascular surgery.

OBJECTIVE: Surgical site infection (SSI) after cardiovascular procedures is a severe complication, potentially leading to high morbidity and mortality. In addition, during the treatment of SSI, rehabilitation is delayed, which can severely impair postoperative recovery. The aim of this study was to assess the effect of vacuum-assisted closure (VAC) therapy on rehabilitation during the treatment of SSI after cardiovascular surgery. METHODS: From January 2008 to March 2015, 10 patients underwent VAC therapy for SSI after cardiovascular operations. The patient characteristics, duration of VAC therapy, time interval from the implementation of VAC to physical therapy (PT) (T1), ambulation (T2) and walking (T3), functional independent measure (FIM), and maximum consecutive walking capacity (MCWC) were retrospectively analyzed. RESULTS: Nine patients underwent mid-sternal incision and one patient underwent thoraco-abdominal incision. The mean time interval from the beginning of VAC therapy to PT, ambulation, and walking was 0.38 ± 0.50, 0.63 ± 0.71, and 1.38 ± 1.86 days, respectively. The average FIM was 84.5 ± 14.0 at the beginning of VAC therapy and 106.7 ± 18.5 at the end of VAC therapy (P = 0.000494). On average, MCWC was 52.3 ± 54.6 m at the installation of VAC therapy and 189.7 ± 152.8 m at the completion of VAC therapy (P = 0.0169). FIM and MCWC improvement rate was better in VAC group than non-VAC group although these data are not suitable for statistical analysis because of a small sample size. CONCLUSIONS: Although further studies are warranted, VAC therapy may have a role in facilitating rehabilitation and improving the prognosis of SSI cases after major cardiovascular operations.

[Total Endoscopic Left Atrial Appendectomy for Valvular Atrial Fibrillation;Report of a Case].

Total endoscopic left atrial appendectomy for non-valvular atrial fibrillation(Af) has been reported to be a safe and effective procedure to prevent cardiogenic thromboembolism and also discontinue oral anticoagulant therapy. On the other hand, open-heart surgery is generally indicated for valvular Af. We report the case of a 67-year-old male patient with valvular Af and recurrent episodes of cardiogenic thromboembolism who underwent total endoscopic left atrial appendectomy. He was diagnosed as having mitral valve stenosis and scheduled for surgery, but presented with cerebellar hemorrhage after warfarin was replaced with heparin in the preoperative phase. Consequently, the operation was cancelled. The case was considered as a good relative indication for total endoscopic left atrial appendectomy, which does not need a cardiopulmonary bypass, to prevent future cardiogenic thromboembolism. The operation was performed and the postoperative course was uneventful.
