Background Robot-assisted minimally invasive heart surgery is an effective alternative when compared with classical approaches. It has a low mortality and postoperative complications and its long-term durability is comparable with conventional techniques., Aim: To report short- and long-term results with the use of a robot-assisted transthoracic approach., Patients and Methods: Review of patients undergoing heart surgery between 2015 and 2019 using a robot assisted minimally invasive technique in a single center. We analyzed demographic characteristics, surgical and early ultrasound results., Results: Thirteen procedures were reviewed, nine mitral valve repairs (MVR) in patients aged 61 ± 21 years (seven males) and four atrial septal defect (ASD) closures in patients aged from 24 to 52 years (three men). For MVR, the average extracorporeal circulation and myocardial ischemia times were 120 ± 20.9 and 89 ± 21 minutes, respectively. The median hospitalization was four days. Two cases of MVR had postoperative complications. There was no mortality. All cases showed improvement in their symptoms. Ultrasound findings showed no postoperative mitral insufficiency except in one case., Conclusions: We report very good results in both complex mitral repair and CIA closure, comparable to centers with high standards in minimally invasive robot-assisted heart surgery.

Introduction: Foot amputation wounds in patients with diabetes are complex and treatment is often difficult. At the moment negative pressure wound therapy (NPWT) is widely used for the treatment of several types of wounds. Nevertheless, the clinical evidence to support the application of this dressing in foot amputation wounds in patients with diabetes is scarce. The aim of this study was to evaluate the efficacy of NPWT compared with standard wound dressing to treat diabetic foot amputation wounds., Patients and Method: Randomised controlled trial. Diabetic patients aged 18 years or older with a foot amputation wound were assigned to treatment with NPWT (A group) or standard wound dressing (B group). Primary efficacy end point was time in reaching 90% of wound granulation. A size of sample of 11 patients per group was used. NPWT was prepared with a polyurethane ether foam dressing, a Nelaton catheter, a transparent adhesive drape and continuous negative pressure of 100 mmHg. The wound was treated every 48-72 h and evaluated weekly. Descriptive and analytical statistics were used., Results: There were 24 patients, with a mean age of 61.8 +/- 9 years (79% men), 12 in each group. The average time to reach 90% of granulation was lower in A group (18.8 +/- 6 days versus 32.3 +/- 13.7 days), a statistically significant difference (P = 0.007)., Conclusion: NPWT reduces the granulation time of diabetic foot amputation wounds by 40%, compared with the standard wound dressing.

Acute dissection of the aorta, although not common, has early and highly lethal complications. The type A dissection is treated with surgery. Patients with type B dissections are treated with surgery if they have complications like rupture, growth or visceral ischemia. Surgery, however, has complications such as spinal cord ischemia. Endovascular grafts have less mortality and complications. We report a 59 years old male patient with a type B dissection complicated with rupture. He was treated successfully with the placement of an endoluminal graft. He was discharged five days after the procedure in good conditions. After one year of follow up, the patient remains asymptomatic.
