RESUMO
PURPOSE: Fulminant myocarditis presents as acute severe heart failure and requires mechanical cardiocirculatory support. Left-ventricular (LV) decompression is necessary for the successful recovery of these patients. This retrospective study aimed to evaluate the functional outcomes of providing central extracorporeal membrane oxygenation (ECMO) with LV decompression for the treatment of refractory fulminant myocarditis. METHODS: Between January 2015 and February 2021, seven consecutive fulminant myocarditis patients (mean age: 41.1 ± 26.1 years) received central ECMO support with transapical LV decompression, with an 18 French cannula integrated into the ECMO circuit in a Y-fashion. The baseline characteristics and postoperative outcomes of the patients were collected. RESULTS: On admission, all patients received prior peripheral ECMO, and 85.7% (6/7) of patients received prior intra-aortic balloon pumping. However, all patients had refractory cardiogenic shock that failed prior to decompression. Six patients recovered successfully after a mean ECMO support of 20.0 ± 11.5 days and five patients had no recurrence of cardiac decompensation. The mean ICU and mean hospital stays were 36.7 ± 23.5 days and 60.6 ± 24.9 days, respectively. Hospital mortality was 28.6% (2/7). Two patients died due to sepsis and stroke during hospitalization. CONCLUSIONS: Central ECMO with an LV vent was effective for fulminant myocarditis refractory to percutaneous cardiopulmonary support therapy and other therapies.

A 41-year-old man stuck himself with needle through his pericardium during suicide attempt. Chest radiography revealed several needles in the bilateral lung fields as well. Computed tomography (CT) and echocardiography showed massive pericardial effusion and a needle penetrating the pericardium. The patient was initially treated conservatively, including pericardial drainage, and, seven days later, we removed the needle using syngo Needle Guidance in hybrid operating room. The length of skin incision was only 2 cm, and the postoperative course was uneventful. No previous studies, to the best of our knowledge, have shown the use of syngo Needle Guidance to remove a needle in the pericardial cavity. This surgical procedure is minimally invasive for the patient.

Left atrial free ball thrombus (LABT) after mitral valve replacement (MVR) is very rare, and sudden death may occur by thrombus impaction to the mitral valve orifice. A 81-year-old woman who underwent MVR and tricuspid annuloplasty ten years ago presented with syncope. She was admitted to a hospital, and echocardiography revealed a LABT. When she took sitting position, she fainted. The free ball thrombus possibly impacted mitral valve orifice. She was transferred to our hospital and an emergent operation was performed. There was a LABT of 4 cm in diameter, which was removed. Postoperative course was uneventful. There are 12case reports which described LABT after MVR, and anticoagulant therapy was insufficient in most of those cases. Strict anticoagulant therapy is important to prevent left atrial thrombus after MVR.

A 72-year-old man, who was treated 10 years earlier with endovascular aortic aneurysm repair, presented with a fever. Considering the concern of stent graft infection, the patient was treated with antibiotics, but his condition did not improve. He underwent stent graft resection and reconstruction with a Dacron graft. Pathological analysis of the aortic wall and computed tomography revealed recurrent intimal sarcoma, and the patient underwent resurgery. During follow-up, he underwent two additional resections for local recurrence, but he died 17 months later. Our results suggest that intimal sarcoma should be considered during the follow-up after endovascular aortic aneurysm repair.
RESUMO
OBJECTIVES: We aimed to identify predictors of postoperative permanent neurological deficits (PNDs) and evaluate the early management of cerebral perfusion in patients undergoing surgical repair of acute type A aortic dissection with cerebral malperfusion. METHODS: Between October 2009 and September 2018, a total of 197 patients with acute type A aortic dissection underwent aortic replacement. Of these, 42 (21.3%) patients had an imaging cerebral malperfusion (ICM). ICM was assessed preoperatively, which also revealed whether dissected supra-aortic branch vessels were occluded or narrowed by a thrombosed false lumen. After September 2017, early reperfusion and extra-anatomic revascularization were performed in cases with ICM. RESULTS: Hospital mortality rates for cases with ICM were 4.8% (2/42). Before September 2017, PND were observed in 6 patients (54.5%) with preoperative neurological symptoms (n = 11), and 7 patients (33.3%) without neurological symptoms (n = 21) in patients with ICM. Occlusion or severe stenosis of supra-aortic branch vessels (odds ratio, 7.66; P < 0.001), regardless of preoperative clinical neurological symptoms, was a risk factor for PND. After September 2017, 7 of 10 patients with ICM underwent early reperfusion and extra-anatomic revascularization. PND did not occur in any of these 7 patients. CONCLUSIONS: Occlusion or severe stenosis of supra-aortic branch vessels is a predictor of PND risk in patients undergoing surgery for acute type A aortic dissection. Early reperfusion and extra-anatomic revascularization may reduce the risk of neurological complications in patients with ICM, with or without neurological symptoms.

We report the successful surgical repair of a cervical aortic arch and diverticulum with a brain circulation anomaly through a clamshell incision. Because of the reliability of selective antegrade cerebral perfusion and superior exposure, we chose an approach through a clamshell incision. We describe the utility of this approach for treating a cervical aortic arch with a diverticulum.
