RESUMO
INTRODUCTION: Accessory left atrial cords are fibroelastic structures found in the left atrium. Left atrial cords may be associated with mitral valve disease, atrial fibrillation, stroke, and other congenital left-side anomalies. METHODS: We presented the case of a man with severe Mitral Regurgitation and two accessories left atrial cords attached to P2 scallop by a single tendon and performed a literature review using PUBMED/MEDLINE, Web of Science, and EMBASE databases on December 4, 2021. RESULTS: According to our review, accessory left atrial cords were found more frequently in women (36 patients, 62%), more frequently attached to the mitral valve (66% of reports) and mitral regurgitation was the most frequently reported pattern of mitral valve disease (64.2%). No other cases of double left atrial cords attached to P2 segment were found. CONCLUSION: Accessory left atrial chords may be related to mitral valve disease and other left-side congenital abnormalities. These structures were found more frequently in females and A2 insertion was the most frequently observed pattern in the review.

BACKGROUND: The use of rapid deployment and sutureless aortic prostheses is increasing. Previous reports have shown promising results on haemodynamic performance and mortality rates. However, the impact of these bioprostheses on left ventricular mass (LVM) regression remains unknown. We decided to study the changes in remodelling and LVM regression in isolated severe aortic stenosis treated with conventional or Perceval® or Intuity® valves. METHOD AND RESULTS: From January 2011 to January 2016, 324 bioprostheses were implanted in our centre. The collected characteristics were divided into 3 groups: conventional valves, Perceval®, and Intuity®, and they were analysed after 12 months. There were 183 conventional valves (56%), 72 Perceval® (22%), and 69 Intuity® (21.2%). The statistical analysis showed significant differences in transprosthetic postoperative peak gradient (23 [18-29] mm Hg vs. 21 [16-29] mm Hg and 18 [14-24] mm Hg, p < 0.001), ventricular mass electrical criteria regression (Sokolow and Cornell products), and 1-year survival (90 vs. 93% and 97%, log rank p value = 0.04) in conventional, Perceval®, and Intuity® groups. CONCLUSIONS: We observed differences in haemodynamic, electrocardiographic, and echocardiographic parameters related to the different types of prosthesis. Patients with the Intuity® prosthesis had the highest reduction in peak aortic gradient and the higher ventricular mass regression. Besides, patients with the Intuity® prosthesis had less risk of mortality during follow-up than the other two groups. Further studies are needed to confirm these findings.

One of the risks of distraction osteogenesis-based techniques is the development of vascular complications, such as pseudoaneurysms associated with the osteotomies performed or the fixation elements of the external fixator used in the procedure. Pseudoaneurysm are formed when the tunica adventitia of the artery is injured, resulting in a gradual and persistent blood extravasation into the surrounding tissues that is encapsulated and connected to the arterial lumen. This report describes a rare case of a late-presentation pseudoaneurysm in the anterior tibial artery resulting from a tibial lengthening procedure aimed at addressing a leg length discrepancy in a 57-year-old female with severe peripheral neuropathy resulting from long-standing poorly controlled diabetes mellitus. We describe the diagnostic process, the treatment options and confirm how the shape of the bony callus can be a reliable indicator of this pathology, as has already been described in the literature.
RESUMO
INTRODUCTION: The aim of this article is to present our experience in performing distal femoral bypass under local anaesthesia for high risk patients. MATERIAL AND METHODS: Lower limb revascularisation surgery under local anaesthesia was performed on 8 patients in our centre between January and May 2010. The common characteristics of the patients were, advanced age, chronic ischaemic heart disease on antiplatelet treatment, and chronic obstructive pulmonary disease (COPD). RESULTS: All 8 patients (100%) tolerated the procedure well without having to resort to sedation or invasive anaesthetic procedures. The receiving artery was the posterior tibial in 6 cases (75%) and the popliteal and peroneal in 1 (12%). Early patency of the graft was achieved 7 patients and 1 had early thrombosis with a supracondylar amputation. The technique used was femoral-popliteal in 1 case, femoral-posterior tibial in 6 cases, and popliteal-peroneal in 1 case. The saphenous vein was the graft used, inverted in 1 patient (12%), and in situ in 7 (88%) with a 3mm BARD™ valvotomy. There were no post-operative complications as regards haemorrhage, infections or death. A minor amputation was performed on 3 patients (37%), and after a mean of 3 months (1-4 months) follow-up, 7 cases were free of major amputation. CONCLUSIONS: Revascularisation of the distal zone of the lower limbs can be safely and effectively performed using local anaesthesia, avoiding the risks of general anaesthesia and without the need to stop antiplatelet treatment. Anatomical problems (obesity) may limit the procedure.

OBJECTIVES: The Edwards Intuity valve is a rapid deployment aortic prosthesis that favours less invasive approaches. However, evidence about the clinical behaviour of their smaller sizes is scarce. Herein, we studied haemodynamic behaviours and clinical outcomes of small Intuity prostheses (19-21 mm) in comparison to larger Intuity prostheses (>21 mm). METHODS: This is an observational study including patients implanted with an Edwards Intuity rapid deployment aortic prosthesis. Patients with prosthesis sizes 19-21 and >21 mm were included. Baseline and perioperative variables, as well as adverse events during the follow-up were recorded and compared between groups. RESULTS: A total of 122 patients (37% female, mean age 75 ± 4.5 years) were included, of whom 54 (45%) were implanted with a small prosthesis and 68 (55%) with a prosthesis >21 mm. There were no significant differences between patients with small Intuity prostheses and patients with larger prostheses regarding in-hospital mortality (2% vs 4%, P = 0.43) or mortality during the follow-up (3.41 vs 2.45 per 100 patients-years; P = 0.58). Survival in the small Intuity valve group was 95% at 1 year and 83% at 6 years, whereas in the larger Intuity valve group was 96% at 1 year and 78% at 6 years. The presence of a small prosthesis did not influence mid-term survival (log-rank P-value = 0.62). CONCLUSIONS: This study showed good clinical performance of Intuity aortic prostheses with appropriate mid-term survival in patients with the small aortic annulus. Thus, the Edwards Intuity rapid deployment aortic prosthesis may be considered as a potential option in patients with the small aortic annulus.

We report a case of acute aortic syndrome in a 64-year-old man who presented with chest pain and hypotension. His electrocardiogram and cardiac troponins were normal. Computed tomography showed hemopericardium of 2.4 cm, but no aortic intimal tear. At surgery, the portion of the aorta affected by adventitial hemorrhage was replaced with a Dacron graft. A nonpenetrating ulcerated plaque was also observed. Massive bleeding through the chest drains with hypotension required emergency reoperation in the intensive care unit. The patient was discharged home on postoperative day 11.

Introducción: El objetivo de este trabajo es transmitir nuestra experiencia en by pass arterial femorodistal bajo anestesia local para pacientes de alto riesgo. Material y métodos De enero a mayo de 2010 hasta 8 pacientes han sido intervenidos en nuestro centro de cirugía de revascularización en miembros inferiores bajo anestesia local. Las características comunes de los pacientes eran la edad avanzada, cardiopatía isquémica crónica en tratamiento con antiagregantes plaquetarios y la enfermedad pulmonar obstructiva crónica (EPOC).Resultados Los 8 pacientes (100%) toleraron de forma adecuada el procedimiento sin recurrir a sedación ni a procedimientos anestésicos invasivos. La arteria receptora fue la tibial posterior en 6 de ellos (75%) y la poplítea y peronea en uno (12%). En 7 casos logramos permeabilidad precoz del injerto y uno presentó trombosis precoz con amputación supracondílea; la técnica empleada fue femoropoplíteo en un caso, femorotibial posterior en 6 casos y poplíteo-peroneo en otro. El injerto utilizado fue la vena safena mayor, invertida en un paciente (12%) e in situ en 7 (88%) con valvulotomo BARD™, 3mm. Las complicaciones postoperatorias fueron del 0% para hemorragia, infección y muerte; en 3 pacientes (37%) amputación menor y, tras un periodo de seguimiento medio de 3 meses (1-4 meses), 7 casos están libres de amputación mayor. Conclusiones La revascularización del territorio distal de los miembros inferiores puede llevarse a cabo mediante anestesia local de forma segura y eficaz, sin necesidad de retirar antiagregantes ni asumir los riesgos de la anestesia general. La anatomía desfavorable (obesidad) puede limitar el procedimiento (AU)
