Uniportal versus multiportal video-assisted thoracoscopic surgery for spontaneous pneumothorax.

Background: Multiportal video-assisted thoracic surgery (mVATS) is the standard approach for the surgical treatment of spontaneous pneumothorax. However, uniportal VATS (uVATS) has emerged as an alternative aiming to minimize surgical morbidity. This study aims to strengthen the evidence on the safety and efficiency of uVATS compared to mVATS.

Surgical mediastinal lymph node staging for non-small-cell lung carcinoma.

Background: The current preferred approach for surgical mediastinal staging of non-small-cell lung carcinoma is video-assisted mediastinoscopy. An alternative technique in which lymph nodes are resected instead of biopsied is video-assisted mediastinoscopic lymphadenectomy (VAMLA) that is suggested to be superior in detecting N2 disease. Yet, evidence is conflicting and furthermore limited by sample size.

Bone suture anchor repair and functional outcome of a triceps tendon rupture, a rare clinical entity.

Triceps tendon rupture is rare and easily missed on presentation. A 58-year-old man was seen in our accident and emergency department with an inability to extend his right elbow against gravity after he fell. Ultrasound and MRI confirmed the suspected diagnosis of a traumatic triceps tendon rupture and excluded additional injuries.

The learning curve of video-assisted mediastinoscopic lymphadenectomy for staging of non-small-cell lung carcinoma.

Objectives: The objective of this study was to define the learning process of video-assisted mediastinoscopic lymphadenectomy (VAMLA) by the assessment of consecutive procedural metrics.

Methods: We conducted a single-centre retrospective observational study of all consecutive VAMLAs performed between 2011 and 2018 for the staging of non-small-cell lung carcinoma. Learning curves were assessed using non-risk adjusted cumulative observed minus expected (CUSUM) failure charts of complications.

Optical imaging versus CT and plain radiography to quantify pectus severity: a systematic review and meta-analysis.

Background: Computed tomography (CT) and two-view chest radiographies are the most commonly used imaging techniques to quantify the severity of pectus excavatum (PE) and pectus carinatum (PC). Both modalities expose patients to ionizing radiation that should ideally be avoided, especially in pediatric patients. In an effort to diminish this exposure, three-dimensional (3D) optical surface imaging has recently been proposed as an alternative method.

Chest tube drainage versus video-assisted thoracoscopic surgery for a first episode of primary spontaneous pneumothorax: a systematic review and meta-analysis.

Primary spontaneous pneumothorax affects up to 28 patients per 100 000 population yearly and is commonly resolved by chest tube drainage. However, drainage is also known to be associated with ipsilateral recurrence rates ranging from 25% to 43%. Preventive video-assisted thoracoscopic surgery (VATS) may be an effective alternative to diminish these recurrence rates and its associated morbidity.

Is visceral flow during intra-aortic balloon pumping size or volume dependent?

Aim: We evaluated the influence of intra-aortic balloon size and volume on mesenteric and renal flows.

Methods: Thirty healthy swine underwent 120-minute ligation of the left anterior descending coronary artery followed by 6 hours of reperfusion. Then, they were randomly assigned to the following five groups of animals, with six animals in each group: no intra-aortic balloon pump (IABP), a short 35-mL IABP, a short 40-mL IABP, a long 35-mL IABP and a long 40-mL IABP.

The ABLA-BOX: An In Vitro Module of Hybrid Atrial Fibrillation Ablation.

Objective: We present the first testing study on the ABLA-BOX, a new in vitro module of hybrid atrial fibrillation ablation.

Methods: ABLA-BOX consists of two chambers that mimic the epicardial and endocardial sides of the heart. The septum between chambers provides catheter access on both sites of the cardiac tissue.

Contact forces during hybrid atrial fibrillation ablation: an in vitro evaluation.

Purpose: Data on epicardial contact force efficacy in dual epicardial-endocardial atrial fibrillation ablation procedures are lacking. We present an in vitro study on the importance of epicardial and endocardial contact forces during this procedure.

Methods: The in vitro setup consists of two separate chambers, mimicking the endocardial and epicardial sides of the heart.

Surgical ablation in patients undergoing mitral valve surgery: impact of lesion set and surgical techniques on long-term success.

Aims: To assess the results and impact of lesion set and surgical technique on long-term success of surgical ablation during mitral surgery.

Methods And Results: The patient population consisted of 685 subjects with persistent and long-standing persistent atrial fibrillation (AF) undergoing cardiac surgery for mitral valve disease as the primary indication and concomitant ablation between January 2003 and January 2012 at three institutions. One hundred and sixty-six underwent unipolar (24.

The Optimal Weaning Strategy for Intraaortic Balloon Counterpulsation: Volume-Based Versus Rate-Based Approach in an Animal Model.

Background: Changes in hemodynamics, coronary circulation, visceral flow, and biochemical marker rate reduction or volume deflation for intraaortic balloon pump discontinuation were assessed.

Methods: Twelve healthy pigs were randomly assigned to two groups, the rate-based (RB, n = 6) and volume-based weaning groups (VB, n = 6). Hemodynamics and visceral and coronary flows were measured at baseline after 2 hours of intraaortic balloon pump 1:1, during the first 5 hours of weaning (frequency rate reduced to 1:2 in the RB group and volume decreased by 10%/h in the VB group), after 1 hour of frequency rate 1:3 in the RB group or a volume decrease by 75% in the VB group, 2 hours after withdrawal, and 4 hours after withdrawal.

Comparing short versus standard-length balloon for intra-aortic counterpulsation: results from a porcine model of myocardial ischaemia-reperfusion.

Objectives: We compare a short and a standard-size balloon with same filling volumes to verify the differences in terms of visceral flow, coronary circulation and haemodynamic performance during aortic counterpulsation in an animal model of myocardial ischaemia-reperfusion injury.

Methods: Eighteen healthy pigs underwent 120-min ligation of the left anterior descending coronary artery followed by 6 h of reperfusion, and they were randomly assigned to have intra-aortic balloon counterpulsation (IABP) with a 40-ml short-balloon (n = 6) or a 40-ml standard-length balloon (n = 6), or to undergo no IABP implantation (controls, n = 6). Haemodynamics and visceral and coronary flows were measured at baseline (t0), at 2 h of ischaemia (t1) and every hour thereafter until 6 h of reperfusion (from tR1 to tR6), respectively.

The "Spacemaker", a New Device for Minimally Invasive Cardiothoracic Surgery: An Evaluation and Feasibility Study.

Objective: Our aim was to evaluate a new inflatable lung retractor, the "Spacemaker", and its efficacy in facilitating minimally invasive cardiothoracic surgery without the need of one lung ventilation or carbon dioxide overpressure insufflation.

Methods: The device was tested in 12 anesthetized pigs (90-100 kg) placed on standard endotracheal ventilation. The device was introduced into the right or left side of the chest, depending on the intended procedure to be performed, via a 3-cm incision in the fifth intercostal space.

Short intra-aortic balloon pump in a swine model of myocardial ischaemia: a proof-of-concept study.

Objectives: This proof-of-concept study examined the haemodynamic performance as well as the coronary and visceral organ perfusion using a new short balloon for intra-aortic counterpulsation (IABP) in a swine model of myocardial ischaemia.

Methods: Eighteen healthy pigs underwent 120-min ligation of the left anterior descending coronary artery followed by 6 h of reperfusion, and they were randomly assigned into 3 groups undergoing IABP implantation with a 35-ml short balloon (n = 6), a 40-ml short balloon (n = 6) or no IABP implantation (controls, n = 6). Haemodynamics, and visceral and coronary flows were measured at baseline (t0), at 2 h of ischaemia (t1) and every hour thereafter until 6 h of reperfusion (from tR1 to tR6), respectively.

Guideline adherence in antithrombotic treatment after concomitant ablation surgery in atrial fibrillation patients.

Objectives: We investigated real-life oral anticoagulation (OAC) treatment after surgical ablation and examined its adherence to current recommendations. We also explored factors related to OAC use preoperatively and at follow-up.

Methods: One hundred and fifteen patients with atrial fibrillation (AF) were evaluated during 12-month follow-up after surgery.
