RESUMO
OBJECTIVE: The aim of this study was to evaluate the impact of the COVID-19 pandemic on the trends of carotid revascularization (endarterectomy [CEA], transfemoral carotid artery stenting [TFCAS]) for symptomatic and asymptomatic carotid stenosis before, during, and after the end of the first lockdown in 2020 in France. METHODS: Nationwide data were provided by the French National Hospital Discharge database (Programme de Médicalisation des Systèmes d'Information). We retrospectively analyzed patients admitted for CEA or TFCAS in all French public and private hospitals during a 9-month period (January-September) in 2017, 2018, 2019, and 2020. Procedures were identified using the French Common Classification of Medical Procedures. Stenoses were considered symptomatic in the presence of stroke and/or transient ischemic attack codes (according to the International Classification of Diseases-Tenth Revision) during the stay, and asymptomatic in the absence of these codes. Hospitalization rates in 2020 were compared with the rates in the same period in the 3 previous years. RESULTS: Between January and September 2020, 12,546 patients were hospitalized for carotid artery surgery (CEA and TFCAS) in France. Compared with the 3 previous years, there was a decrease in hospitalization rates for asymptomatic (-68.9%) and symptomatic (-12.6%) CEA procedures in April, starting at the pandemic peak concomitant with the first national lockdown. This decrease was significant for asymptomatic CEA (P < .001). After the lockdown, while CEA for asymptomatic stenosis returned to usual activity, CEA for symptomatic stenosis presented a significant rebound, up 18.52% in August compared with previous years. Lockdown also had consequences on TFCAS procedures, with fewer interventions for both asymptomatic (-60.53%) and symptomatic stenosis (-16.67%) in April. CONCLUSIONS: This study demonstrates a severe decrease for all interventions during the first peak of the COVID-19 pandemic in France. However, the trends in the postlockdown period were different for the various procedures. These data can be used to anticipate future decisions and organization for cardiovascular care.

PURPOSE: The STABILISE technique has extended the treatment of aortic dissection to the thoracoabdominal aorta to achieve complete aortic remodeling. The aim of this multicenter study was to analyze the short- and midterm anatomical results of the STABILISE technique. MATERIALS AND METHODS: We retrospectively analyzed patients treated with the STABILISE technique for complicated aortic dissection at 3 French academic centers. The aortic diameter at different levels was measured preoperatively, postoperatively, and at 1 year. RESULTS: Between 2018 and 2020, 58 patients, including 47 men (average patient age: 60±11 years), were treated for type B aortic dissection in 34 cases and residual aortic dissection after type A repair in 24 cases. Three (5.2%) patients died postoperatively. Complete aortic remodeling (false lumen thrombosis and complete reapposition of the intimal flap) was achieved in 45/55 patients (81.8%), and false lumen thrombosis in the thoracic aorta was achieved in 52/55 patients (94.5%). At 1 year, with a computed tomographic (CT) scan available for 98.2% (54/55) of patients, we observed a significant decrease in the maximal thoracic aortic diameter and a significant increase in the aortic diameter at the bare-stent level compared with the preoperative CT scan. Severe aortic angulation (p=0.024) was a risk factor for incomplete aortic remodeling and significantly increased the aortic diameter (p=0.032). Chronic aortic dissection was associated with an increased risk of incomplete aortic remodeling (p=0.002). CONCLUSIONS: STABILISE for complicated aortic dissection results in false lumen thrombosis, complete reapposition of the intimal flap, and a decrease in the maximum aortic diameter in most cases. Incomplete reapposition of the intimal flap, which is more frequent in cases of chronic aortic dissection and severe aortic angulation, is a risk factor for a significant increase in the aortic diameter at the bare-stent level, and this risk justifies close follow-up and better patient selection. CLINICAL IMPACT: STABILISE technique for complicated aortic dissection results in false lumen thrombosis, complete aortic remodeling and a decrease in the maximum aortic diameter in most cases. At the bare-stent level, incomplete reapposition of the intimal flap, more frequent in chronic aortic dissection and severe aortic angulation, is a risk factor for an increased aortic diameter. This finding justifies close follow-up and better patient selection; thus, the STABILISE technique should be used with care in chronic aortic dissection and severe aortic angulation.

BACKGROUND: There are still gaps regarding the impact of the nationwide lockdown on non-COVID-19 emergency hospitalizations. This study aims to describe the trends in hospitalizations for cardiovascular surgical emergencies in France, before, during and after the first lockdown. MATERIALS AND METHODS: All adults admitted for mechanical complications of myocardial infarction (MI), aortic dissection, aortic aneurysm rupture, acute and critical limb ischemia, circulatory assistance, heart transplantation and major amputation were included. This retrospective cohort study used the French National Hospital Discharge database. The numbers of hospitalizations per month in 2020 were compared to the previous three years. RESULTS: From January to September 2020, 94,408 cases of the studied conditions were reported versus 103,126 in the same period in 2019 (-8.5%). There was a deep drop in most conditions during the lockdown, except for circulatory assistance, which increased. After the lockdown, mechanical complications of MI and aortic aneurysm rupture increased, and cardiac transplantations declined compared with previous years. CONCLUSION: We confirmed a deep drop in most cardiovascular surgical emergencies during the lockdown. The post-lockdown period was characterized by a small over-recovery for mechanical complications of MI and aortic aneurysm rupture, suggesting that many patients were able to access surgery after the lockdown.
RESUMO
BACKGROUND: Cardiopulmonary bypass (CPB) induces a systemic inflammatory response (SIRS) and affects the organ vascular bed. Experimentally, the lack of pulsatility alters myogenic tone of resistance arteries and increases the parietal inflammatory response. The purpose of this study was to compare the vascular reactivity of the internal thoracic arteries (ITAs) due to the inflammatory response between patients undergoing coronary artery bypass grafting (CABG) under CPB with a roller pump or with a centrifugal pump. METHODS: Eighty elective male patients undergoing CABG were selected using one or two internal thoracic arteries under CPB with a roller pump (RP group) or centrifugal pump (CFP group). ITA samples were collected before starting CPB (Time 1) and before the last coronary anastomosis during aortic cross clamping (Time 2). The primary endpoint was the endothelium-dependent relaxation of ITAs investigated using wire-myography. The secondary endpoint was the parietal inflammatory response of arteries defined by the measurements of superoxide levels, leukocytes and lymphocytes rate and gene expression of inflammatory proteins using. Terminal complement complex activation (SC5b-9) and neutrophil activation (elastase) analysis were performed on arterial blood at the same times. RESULTS: Exposure time of ITAs to the pump flow was respectively 43.3 minutes in the RP group and 45.7 minutes in the CFP group. Acetylcholine-dependent relaxation was conserved in the two groups whatever the time. Gene expression of C3 and C4a in the artery wall decreased from Time 1 to Time 2. No oxidative stress was observed in the graft. There was no difference between the groups concerning the leukocytes and lymphocytes rate. SC5b-9 and elastase increased between Time 1 and Time 2. CONCLUSION: Endothelium-dependent relaxation of the internal thoracic arteries was preserved during CPB whatever the type of pump used. The inflammatory response observed in the blood was not found in the graft wall within this time frame.
