Large mediastinal masses are rare, and encompass a wide variety of diseases. Regardless of the diagnosis, all large mediastinal masses may cause compression or invasion of vital structures, resulting in respiratory insufficiency or hemodynamic decompensation. Detailed preoperative preparation is a prerequisite for favorable surgical outcomes and should include preoperative multimodality imaging, with emphasis on vascular anatomy and invasive characteristics of the tumor. A multidisciplinary team should decide whether neoadjuvant therapy can be beneficial. Furthermore, the anesthesiologist has to evaluate the risk of intraoperative mediastinal mass syndrome (MMS). With adequate preoperative team planning, a safe anesthesiological and surgical strategy can be accomplished.
Only mild signs of oxidative stress and no renal dysfunction were found during and after off-pump CABG compared with on-pump CABG.
Background: Persistent atrial fibrillation (AF) is associated with higher stroke and mortality risk than paroxysmal AF (pAF). Outcomes of catheter or surgical ablation are worse in patients with persistent AF than in pAF, and the optimal invasive rhythm control strategy has not been established. Purpose: We provide a contemporary systematic overview on efficacy and safety of catheter and minimallyinvasive surgical ablation for persistent AF. Methods: We systematically searched EMBASE, MEDLINE and CENTRAL from inception to July 2018 for randomized trials on surgical and catheter ablation, and included all study arms on persistent AF. Outcome was AF freedom after ≥12 months follow-up without AAD use. Random effects models were used to calculate proportions with 95%-confidence intervals. Safety consisted of adverse events during treatment and follow-up. Results: We included 6 studies on minimally-invasive surgical ablation and 56 on catheter ablation, involving 7624 patients with persistent AF. AF Freedom at 12 months was 69% (95%CI 64-74%) after surgical and 51% (95%CI 46-56%) after catheter ablation. More severe procedural adverse events occurred with surgery than with catheter ablation. Conclusions: In persistent AF patients, minimally-invasive surgical ablation is associated with more procedural complications, but higher AF freedom. As adverse events after surgical ablation appear more severe than in catheter ablation, a patient-tailored therapy choice is warranted.
AimsThoracoscopic surgical ablation has evolved into a successful strategy for symptomatic atrial fibrillation (AF) refractory to other therapy. More widespread referral is limited by the lack of information on potential complications. Our aim was to systematically evaluate 30-day complications of totally thoracoscopic surgical ablation.Methods and resultsWe retrospectively studied consecutive patients undergoing totally thoracoscopic surgical ablation at a referral centre in the Netherlands (2007–2016). Patients received pulmonary vein isolation, with additional lesion lines as needed, and left atrial appendage exclusion. The primary outcomes were freedom from any complications and freedom from irreversible complications at 30-days. Secondary outcomes included intra- and post-operative complications according to severity. Included were 558 patients with median age 62 years (interquartile range 56–68 years), 70% male and 53% with a previous failed catheter ablation. The cohort consisted of 43% paroxysmal AF, 47% persistent AF, and 10% long-standing persistent AF. Freedom from any 30-day complication was 88.2%, and from complications with life-long affecting consequences 97.5%. The intra-operative complication rate was 2.3% with no strokes or death observed. The median hospital length of stay was 4 days. The percentage of patients with major and minor complications at 30-days was 3.2% and 8.1%, respectively, with one patient dying of an ischaemic stroke. The only patient groups with excess complications were women aged ≥70 years and patients with a history of congestive heart failure.ConclusionsTotally thoracoscopic ablation is associated with a low complication rate in a referral centre and may be a useful alternative to other rhythm control strategies.
