Successful Medical Treatment for Aortoesophageal Fistula after Thoracic Endovascular Aortic Repair.

Aortoesophageal fistula is a fatal disease that requires surgical treatment. Due to the patient's wishes, we chose medical treatment for aortoesophageal fistula after thoracic endovascular aortic repair for a pseudoaneurysm in the distal anastomotic site after total aortic arch replacement. Satisfactory early and long-term outcomes were obtained with complete fasting and appropriate antibiotics.

Nitric Oxide Inhalation and V-V ECMO for Severe Respiratory Failure after Acute Type A Aortic Dissection Surgery.

A 65-year-old man was admitted to our hospital with acute type B aortic dissection that extended into both common iliac arteries with an occluded right common iliac artery and large bullae in bilateral upper lung fields. Femoro-femoral arterial bypass surgery with an artificial blood vessel was performed. Two days postoperatively, acute type B aortic dissection progressed to acute type A aortic dissection. Emergency total arch graft replacement (TAR) was performed through a median sternotomy on the same day. Immediately following TAR, the patient experienced hypoxemia. Acute respiratory distress syndrome (ARDS) was diagnosed following TAR for acute aortic dissection with pneumonia. Nitric oxide inhalation (NOI) therapy was commenced at 20 ppm from the fourth day post-surgery. However, 6 d following TAR, he developed bilateral pneumothorax due to ruptured bullae requiring chest tube management and thoracoscopic left upper lobe bullectomy. Eight days following TAR, veno-venous extracorporeal membrane oxygenation (V-V ECMO) was initiated and NOI therapy was completed. V-V ECMO was withdrawn 18 d after TAR. Postoperatively, after 2 years 3 months, the patient remains ambulatory without assistance, walking to the outpatient clinic.

Echocardiography-guided aortic cannulation by the Seldinger technique for type A dissection with cerebral malperfusion.

OBJECTIVE: The purpose of this study was to assess the efficacy of echocardiography-guided ascending aortic central cannulation using the Seldinger technique during surgery for type A acute aortic dissection complicated by stroke due to cerebral malperfusion. METHODS: Between April 2007 and December 2017, 208 patients with type A acute aortic dissection underwent echocardiography-guided ascending aortic central cannulation using the Seldinger technique. We analyzed 16 of these patients (7.7%; median age, 63 years; 8 men) with stroke due to cerebral malperfusion, including 10 in a comatose state (Glasgow Coma Scale ≤8) and 6 with hemiplegia (manual muscle test ≤1) on hospital arrival. The Modified Rankin Scale was used to evaluate activities of daily living. RESULTS: The median time from onset of symptoms to establishment of cardiopulmonary bypass was 327 (176-561) minutes. The median time from the start of surgery to establishment of cardiopulmonary bypass was 34 (30-44) minutes. The mortality rate was 6.3% (1/16). In patients with preoperative coma, the Glasgow Coma Scale improved significantly after surgery from 4.5 to 15 at 30 days (P < .001). In patients with preoperative hemiplegia, 4 showed improved motor function on the manual muscle test score at 90 days. In all patients, Modified Rankin Scale scores improved significantly from 5.0 preoperatively to 1.0 after follow-up (P < .001). CONCLUSIONS: Echocardiography-guided ascending aortic central cannulation using the Seldinger technique has potential as a rapid and reliable perfusion route during surgery for type A acute aortic dissection complicated by stroke due to cerebral malperfusion.

Non-heart transplant surgical approaches with left ventricular restoration and mitral valve operation for advanced ischaemic cardiomyopathy.

OBJECTIVES: The aim of this study was to assess long-term outcomes of non-heart transplant surgical approaches to advanced ischaemic cardiomyopathy (ICM), including left ventricular restoration (LVR) and mitral valve operation. METHODS: Since September 2002, 102 consecutive patients (mean age 65, 18 females) with advanced ICM [ejection fraction (EF) <40%, left ventricular end-systolic volume index (LVESVI) > 60 ml/m(2)] were treated using non-heart transplant procedures. A total of 84 patients with asynergy of large scar exceeding 35% of left ventricular (LV) perimeter underwent LVR, and 30 patients with greater than or equal to moderate mitral regurgitation (MR) underwent mitral valve operation such as annuloplasty (n = 23) and valve replacement (n = 7). Patients were divided into four groups according to their interagency registry for mechanically assisted circulatory support (INTERMACS) profiles: Profile 1-2 (the highest levels of clinical compromise; n = 9), Profile 3-4 (n = 40), Profile 5-6 (n = 32) and Profile ≥ 7 (n = 21). We compared the four groups, looking at survival, major adverse cardiac and cerebrovascular event (MACCE), New York Heart Association (NYHA) status, LV volume and function. RESULTS: The overall 8-year survival including 3 hospital deaths (2.9%) was 64.3% without sudden death due to arrhythmia. Ninety-nine survivors showed significant improvement in the mean NYHA status, from 2.9 to 1.4, and the mean EF (33.2-41.7%) (P < 0.0001). The mean LVESVI was significantly reduced from 104.1 to 61.4 ml/m(2) (41% volume reduction) (P < 0.0001). Seven-year survival in patients with Profiles 1-2, 3-4, 5-6 and ≥ 7 were 50.0, 57.2, 60.3 and 95.2%, respectively (P = 0.13). Freedom from MACCE at 5 years in patients with Profiles 1-2, 3-4, 5-6 and ≥ 7 were 29.6, 47.0, 67.2 and 95.2%, respectively (P = 0.0067). The improvements in NYHA status were significantly greater in patients with higher levels of clinical compromise (P < 0.0001), although, there was no significant difference in LV volume reduction and functional improvement among the four groups. Patients with Profile ≥ 7 had significantly better survival at 7 years (hazard ratio (HR): 0.11, P = 0.046) and freedom from MACCE at 5 years (HR: 0.053, P = 0.0066) compared with patients with Profiles 1-2. CONCLUSIONS: Our non-heart transplant surgical approaches using LVR and mitral valve operation for advanced ICM yielded excellent long-term outcomes in terms of survival and NYHA status, even in patients who are potential candidates for heart transplantation or LV assist devices; and are encouraging in a very particular situation where heart transplantation is limited due to organ storage.

Long-term outcomes and comparison after conventional coronary artery bypass grafting for left main disease between patients classified as percutaneous coronary intervention recommendation classes II and III.

OBJECTIVES: We retrospectively analysed long-term outcomes after conventional coronary artery bypass grafting (CABG) between patients having left main (LM) disease who should have been assigned class II and those assigned class III recommendation for percutaneous coronary intervention (PCI) according to the 2010 European Society of Cardiology and the European Association for Cardio-Thoracic Surgery guidelines. METHODS: From January 2000 to December 2009, conventional CABG was routinely employed in 180 consecutive patients with previously untreated and stable LM lesion. A comparison between two groups (CABG for PCI class II and CABG for PCI class III) was performed, looking at the primary endpoint of major adverse cardiac and cerebrovascular events (MACCE), including all-cause death, stroke [cerebral vascular accident (CVA)], myocardial infarction (MI) and repeat revascularization. We also analysed the effects of variables on MACCE at 8 years after the operation. RESULTS: The overall 8-year MACCE rates were significantly lower in the CABG for PCI class II group than in the CABG for PCI class III group (9.7% class II vs 31.1% class III; P = 0.0005). This was largely because of an increased rate of repeat revascularization (1.2% class II vs 13.8% class III; P = 0.0029). The cumulative rate of the combined outcomes of all death/CVA/MI was significantly lower in the CABG for PCI class II group (8.5% class II vs 19.2% class III; P = 0.048); there was no observed difference between the groups for all-cause death, CVA and MI. The SYNTAX score was demonstrated to be the only significant predictor of combined outcomes (Death/CVA/MI) at 8 years [odds ratio (OR) 1.05, P = 0.023], repeat revascularization at 8 years (OR 1.11, P = 0.0013) and MACCE at 8 years (OR 1.07, P < 0.0001). CONCLUSIONS: In our routine strategy of conventional CABG for LM disease, patients believed to be PCI candidates for LM disease have significantly better long-term outcomes as characterized by combined outcomes (Death/CVA/MI), repeat revascularization and MACCE. These results provide a suitable benchmark against which long-term outcomes of PCI for LM disease can be compared. The SYNTAX score, which was introduced to determine treatment for complex coronary disease, is indicative of long-term outcomes after CABG for LM disease.
