Clinical Presentation and Management of the Cervical Aortic Arch in the Adult Population: A Review of Case Reports.

The cervical aortic arch (CAA) is an uncommon congenital anomaly in aortic development, characterized by an elongated aortic arch extending at or above the medial ends of the clavicles. Our objective was to examine the clinical and surgical characteristics of this infrequent condition in the adult population. PubMed, ScienceDirect, SciELO, DOAJ, and Cochrane Library databases were searched until December 2023 for case reports describing the presence of a cervical aortic arch in patients aged ≥18 years. Case reports and series were included if the following criteria were met: (1) description of the cervical aortic arch, (2) age ≥18 years, and (3) English language. The literature search identified 2,325 potentially eligible articles, 61 of whom met our inclusion criteria and included a combined number of 71 patients. Mean age was 38.6 ± 15.4 years, with a female prevalence of 67.1% (47/70). Two-thirds of the CAA were left-sided (48/71, 67.6%), and 62.0% (44/71) of patients presented a concomitant arch aneurysm. Asymptomatic patients were 45.7% (32/70), while of those that were symptomatic, 60.5% (23/38) had symptoms related to vascular-induced compression of trachea and esophagus. Surgery was performed in 42 patients (62.7%) among 67 cases that reported the patient's treatment, and 5 patients (11.9%) among those surgically treated underwent the procedure through an endovascular approach. CAA is an uncommon congenital abnormality that presents challenges in diagnosis and treatment due to its high anatomical variability, diverse clinical manifestations, and presence of concomitant diseases. Surgery seems to be a safe and effective option for the resolution of symptoms.

[Multidisciplinary therapy for recurrent pancreatic cancer].

We report 2 cases of pancreatic cancer with distant organ metastasis. Case 1: A 67-year-old man with pancreatic cancer (T3N0M0, Stage III) underwent pancreaticoduodenectomy (PD). A follow-up computed tomography (CT) scan performed 48 months after the primary resection detected two masses in his right lung, which were treated by stereotactic body radiotherapy ( SBRT). Twenty-three months after SBRT, the patient is alive. Case 2: A 54-year-old woman with pancreatic cancer (T3N1M0, Stage III) underwent PD. A follow-up CT scan performed 12 months after the primary resection detected 3 masses in her liver, which were treated by SBRT. The patient died because of lymph node metastasis of the pancreatic cancer 32 months after SRT.

Stroke Prevention With Prophylactic Left Atrial Appendage Occlusion in Cardiac Surgery Patients Without Atrial Fibrillation: A Meta-Analysis of Randomized and Propensity-Score Studies.

BACKGROUND: The role of left atrial appendage occlusion (LAAO) in patients without previous atrial fibrillation (AF) is not established. This meta-analysis was conducted on patients with normal sinus rhythm who underwent cardiac surgery, with and without concomitant LAAO, to evaluate its effect on the incidence of cerebrovascular accidents (CVAs). METHODS: A systematic review was conducted from inception until December 2023 for randomized and propensity-score studies comparing CVA in patients without AF undergoing cardiac surgery with or without LAAO. RESULTS: Six studies met our inclusion criteria with a total of 4130 patients: 2146 in the LAAO group and 1984 in the no-LAAO group. The risk ratio of postoperative AF was 1.05 (95% CI, 0.86-1.28); P=0.628. The CVA rates at 5 years were 6.8±1.0% in the no-LAAO group and 4.3±0.8% in the LAAO group (log-rank P=0.021). The Cox regression analysis for CVA in patients undergoing LAAO reported a hazard ratio of 0.65 (95% CI, 0.45-0.94); P=0.022. Landmark analysis at 4 years highlighted a significant difference in overall survival between no-LAAO and LAAO groups, 86±12.2% versus 89.6±11.0%; P=0.041. CONCLUSIONS: In this meta-analysis of patients without previous AF undergoing cardiac surgery, LAAO was associated with a decreased risk of CVA, no difference in the incidence of postoperative atrial fibrillation, and a significant overall survival benefit at a 4-year landmark analysis. Although these findings support LAAO, the randomized LeAAPS trial (Left Atrial Appendage Exclusion for Prophylactic Stroke Reduction Trial), LAA-CLOSURE trial (A Randomized Prospective Multicenter Trial for Stroke Prevention by Prophylactic Surgical Closure of the Left Atrial Appendage in Patients Undergoing Bioprosthetic Aortic Valve Surgery), and LAACS-2 trial (Left Atrial Appendage Closure by Surgery-2) will help define the effectiveness of LAAO in patients undergoing cardiac surgery who have risk factors for AF and CVA.

Impact of mitral stenosis on early and late outcomes of transcatheter aortic valve replacement for aortic stenosis: a single-center analysis.

OBJECTIVES: To assess the impact of concomitant mitral stenosis (MS) on early and late outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis. METHODS: This study involved 952 patients undergoing TAVR for severe tricuspid aortic stenosis. The patients were classified into 3 groups: without MS, with progressive MS, and severe MS (mitral valve area ≤ 1.5 cm2). Clinical outcomes between these groups were compared. RESULTS: The median age of the overall cohort was 82 years, and patients in the progressive (n = 49) and severe (n = 24) MS groups were more likely to be female than those in the no-MS group (n = 879). Periprocedural mortality rate was lowest in the no-MS group (1.8%) compared with the progressive (4.1%) and severe (4.2%) MS groups, which were not significantly different (P = .20). During 5 years of follow-up (median: 27, range: 0-72 months), there was no significant difference in all-cause mortality (log-rank P = .99), a composite of all-cause mortality or rehospitalization for heart failure (log-rank P = .84), or cardiovascular death (log-rank P = .57) between groups. Although crude analysis showed a significant difference in rehospitalization for heart failure in the severe MS group compared with the no-MS group (P = .049), the difference was not significant in the multivariate analysis (adjusted hazard ratio: 1.36 [95% CI, 0.66-2.80], P = .41). CONCLUSIONS: TAVR can be safely performed in patients with severe tricuspid aortic stenosis and concomitant MS, with early and mid-term outcomes comparable to those in patients without MS.

Clinical Outcomes After Durable Mitral Valve Repair for Ischemic Mitral Regurgitation.

BACKGROUND: This study aimed to clarify the incidence and determinants of postoperative adverse events in patients with ischemic cardiomyopathy who achieved long-term durable mitral valve repair. METHODS: Between 1999 and 2015, 166 patients with chronic ischemic mitral regurgitation (MR) and a left ventricular ejection fraction ≤40% underwent restrictive mitral annuloplasty. During follow-up (65 ± 34 months), echocardiographic assessments were performed 809 times (mean, 4.9 ± 2.4 times), and 20 patients who had postoperative recurrent MR (moderate or severe) were excluded. Finally, 146 patients (aged 68 [63-75] years) whose MR was well controlled over time were included. RESULTS: A total of 61 deaths or 27 readmissions for heart failure were observed in 76 patients (52%). Among hospital survivors, age (adjusted hazard ratio, 1.05; P = .001) and estimated glomerular filtration rate (adjusted hazard ratio, 0.61; P = .001) were identified as independent predictors of long-term mortality or readmission for heart failure. The degree of postoperative left ventricular function recovery was comparable between patients with and without adverse events. However, the former group showed greater values for systolic pulmonary artery pressure, tricuspid regurgitation severity, inferior vena cava dimension, and plasma brain natriuretic peptide level throughout the follow-up period (group effect P < .05 for all). CONCLUSIONS: Approximately 50% of patients died or were hospitalized for heart failure even in the absence of recurrent MR during the 5-year follow-up, a finding indicating that durable mitral repair does not always lead to favorable clinical outcomes. The adverse events may have been related to volume overload secondary to impaired renal function and less favorable pulmonary hemodynamics.
