Carbon dioxide (CO) has been extensively used to allow laparoscopic procedures, due to its extensive advantages in obtaining a fairly innocuous pneumoperitoneum to allow visceral dissection. Its use in video assisted thoracic surgery (VATS) has seldom been described. We present our experience in more than 100 patients, operated for various thoracic pathologies, in whom we created a surgical pneumothorax to allow different surgeries to be undertaken.

Introduction The stent assisted balloon induced intimal disruption and relamination in aortic dissection repair (STABILISE) technique is being increasingly used for the treatment of complicated aortic dissections. However, as it is a fairly recent technique, the scientific information is limited. Report In this paper we report two cases of the STABILISE technique associated with procedures in the ascending aorta and supra-aortic trunks, consisting of a “frozen elephant trunk” procedure in one case and in the other, a carotid endarterectomy associated with reimplantation of the vertebral artery and partial arch debranching. Discussion In conclusion, while acknowledging the need for longer follow up and greater experience to support the safety and efficacy of this procedure, the two cases reported confirm that the STABILISE technique is a valid endovascular alternative in the treatment of complicated aortic dissections.
Cardiac surgery is almost universally performed through a median sternotomy, an approach which is painful, unestethical, and prone to life-threatening infections. Minimally invasive cardiac surgery has tried to avoid problems associated with full sternotomy for many years. Recently, uniportal thoracic surgery was shown to be very advantageous when compared to standard thoracotomy and classical video assisted thoracic surgery (VATS). Despite very good results in lung surgery, cardiac surgery through a single thoracic port has rarely been attempted and successfully conducted. The authors present the rational, the technique, and their experience in cardiac single thoracic port surgery (CSTPS).
Background: Anterior mediastinal tumours account for 50% of all mediastinal masses. Surgical intervention is the standard approach for their diagnosis or treatment. Minimally invasive techniques have gained significant popularity in the last few decades due to the obvious advantages that they offer. We will describe a series composed of the first 20 patients who were submitted to a new minimally invasive videoassisted technique, which uses an inframammary incision approach involving a Thoratrak rib spreader and a Rultract Skyhook retractor. Methods: A retrospective study was undertaken, involving all the patients in our department who were submitted to a resection of their anterior mediastinal masses by inframammary incision, using a Thoratrak rib spreader, a Rultract Skyhook retractor and video assistance. Results: A total of 20 patients were included, with a mean age of 52.6. The mean surgery duration was 47 minutes, with an intraoperative blood loss of 70 mL. The mean period of hospitalisation was 2.9 days. No patients underwent conversion to open surgery, and there were no major complications. The mean size of the masses that were excised was 13.9 cm, with a mean weight of 77.3 g. The surgical margins were all free of tumour tissue, and no early recurrence was observed during the postoperative follow-up period. Conclusions: Video-assisted thoracoscopic surgery (VATS) and robot assisted thoracic surgery (RATS) account for most of the minimally invasive procedures. However, VATS has certain limitations in terms of deep perception and manoeuvrability, and RATS has the disadvantage of lacking tactile and force feedback for the surgeon. The inframammary technique allows for safe direct dissection around the vascular and nervous structures, ensuring a complete observation of the anterior mediastinum and its structures. The findings in the present study suggest that this technique is useful. We had good surgical results, short surgery times and very low blood loss, and all tumours were totally resected, with tumour-free surgical margins. The size and the right lateralisation of the mass did not present any contraindications, and the learning curve and investment were minimal. In conclusion, the inframammary approach could be a safe and useful approach for treating anterior mediastinal pathology.
Background Aortic valve stenosis is the most common adult valve disease in industrialized countries. The aging population and the increase in comorbidities urge the development of safer alternatives to the current surgical treatment. Sutureless bioprosthesis has shown promising results, especially in complex procedures and in patients requiring concomitant surgeries. Objectives Assess the clinical and hemodynamic performance, safety, and durability of the Perceval® prosthetic valve. Methods This single‐center retrospective longitudinal cohort study collected data from all adult patients with aortic valve disease who underwent aortic valve replacement with a Perceval® prosthetic valve between February 2015 and October 2020. Of the 196 patients included (mean age 77.20 ± 5.08 years; 45.4% female; mean EuroSCORE II 2.91 ± 2.20%), the majority had aortic stenosis. Results Overall mean cross‐clamp and cardiopulmonary bypass times were 33.31 ± 14.09 min and 45.55 ± 19.04 min, respectively. Mean intensive care unit and hospital stay were 3.32 ± 3.24 days and 7.70 ± 5.82 days, respectively. Procedural success was 98.99%, as two explants occurred. Four valves were reimplanted due to intraoperative misplacement. Mean transvalvular gradients were 7.82 ± 3.62 mmHg. Pacemaker implantation occurred in 12.8% of patients, new‐onset atrial fibrillation in 21.9% and renal replacement support was necessary for 3.1%. Early mortality was 2.0%. We report no structural valve deterioration, strokes, or endocarditis, and one successfully treated valve thrombosis. Conclusions Our study confirms the excellent clinical and hemodynamic performance and safety of a truly sutureless aortic valve, up to a 5‐year follow‐up. These results were consistent in isolated and concomitant interventions, solidifying this device as a viable option for the treatment of isolated aortic valve disease.
Melanoma is a tumor that virtually involves any tissue and commonly metastasizes to the heart. It is usually not diagnosed because of the absent/nonspecific cardiac signs and symptoms. Herein, we present a case of a 41-year-old man without any cardiovascular risk factor, admitted to the emergency room with chest pain, diagnosed with a myocardial infarction. Due to the presence of a mass adjacent to the mitral valve on the cardiac ultrasound examination, causing mitral regurgitation, the patient was referred to surgery. Pathological analysis of the excised specimens diagnosed the melanoma. The chemotherapy was started and achieved a partial response. Cardiac metastases usually affect the myocardium, leaving the valves unaffected. In this case, the acute coronary syndrome was the first manifestation of the malignant melanoma. We highlight the high level of suspicion needed in these cases.
