BACKGROUND: Early detection of respiratory overload is crucial to mechanically ventilated patients, especially during phases of spontaneous breathing. Although a diversity of methods and indices has been established, there is no highly specific approach to predict respiratory failure. This study aimed to evaluate acceleration sensors in abdominal and thoracic wall positions to detect alterations in breathing excursions in a setting of gradual increasing airway resistance. METHODS: Twenty-nine healthy volunteers were committed to a standardized protocol of a two-minutes step-down spontaneous breathing on a 5 mm, 4 mm and then 3 mm orally placed endotracheal tube...

BACKGROUND: Pulmonary artery intimal spindle cell sarcomas are rare and carry with them a poor prognosis and high rate of recurrence. In extremely rare cases, this tumor can infiltrate the pulmonic valve and manifest as adult-onset pulmonic stenosis. CASE PRESENTATION: We report an unusual case of a patient with symptomatic, adult-onset severe pulmonic stenosis who was referred for possible balloon valvuloplasty but was subsequently found to have pulmonary artery intimal sarcoma infiltrating the pulmonary valve leading to progressive exertional dyspnea...

BACKGROUND: Pulmonary visceral subpleural hematoma is rare. We report visceral subpleural hematoma of the left diaphragmatic surface following left upper division segmentectomy. This very rare case was difficult to distinguish from thoracic abscess. CASE PRESENTATION: A 68-year-old man with hypertension had undergone video-assisted thoracoscopic left upper division segmentectomy for suspected lung carcinoma. Deep vein thrombosis of the lower leg was identified and edoxaban, a so-called novel oral anticoagulant, was started on postoperative day 7...

BACKGROUND: Evidence suggests that elective cardiac patients are at risk of functional and psychological deterioration in the time preceding surgery. This poses a risk to successful post-operative rehabilitation. This prospective one-group pre-test, post-test evaluation was designed to assess a clinical Pre-operative Rehabilitation (PREHAB) home-based exercise programme, to optimise pre-operative physical function and frailty in patients awaiting elective Coronary Artery By-Pass Graft (CABG) or Valve Surgery...

BACKGROUND: Few studies focused on evaluating the impacts of preoperative severe left ventricular dysfunction on clinical outcomes of patients undergoing off-pump coronary artery bypass grafting surgery (OPCAB). This single center retrospective study aimed to evaluate the impacts of severe left ventricular dysfunction on in-hospital and mid-term clinical outcomes of Chinese patients undergoing first, scheduled, and isolated OPCAB surgery. METHODS: From January 2010 to December 2014, 2032 eligible patients were included in this study and were divided into 3 groups: a severe group (patients with preoperative left ventricular ejection fraction (LVEF) of ≤35%, n = 128), an impaired group (patients with preoperative LVEF of 36-50%, n = 680), and a normal group (patients with preoperative LVEF of >50%, n = 1224)...

BACKGROUND: Advanced heart failure treated with a left ventricular assist device is associated with a higher risk of right heart failure. Many advanced heart failures patients are treated with an ICD, a relative contraindication to MRI, prior to assist device placement. Given this limitation, left and right ventricular function for patients with an ICD is calculated using radionuclide angiography utilizing planar multigated acquisition (MUGA) and first pass radionuclide angiography (FPRNA), respectively...

BACKGROUND: Aortic dissection (AD) represents a clinically uncommon aortic pathology which predicts a dismal prognosis if not promptly treated. In acute Debakey type I AD (ADIAD), aortic lesion extends from aortic root to even distal abdominal aorta among which aortic arch and its three main branches still remain a great surgical challenge for repair and reconstruction. Several decades have witnessed the painstaking efforts of cardiovascular surgeons across the globe for optimizing the surgical procedures, from total or hemi-arch replacement, "elephant trunk" technique to branched stent graft...

BACKGROUND: Reoperative cardiac valve surgery via sternotomy is associated with a substantial morbidity and mortality. This study evaluated the right anterolateral thoracotomy for high-risk patients undergoing mitral and tricuspid valve redo procedures. METHODS: Out of a series of 173 patients undergoing redo cardiac valve surgery, 24 patients were reoperative via the right anterolateral thoracotomy as the high-risk group on the basis of the proximity of the heart and great vessels to the sternum and the presence and location of patent bypass grafts...

EDITORIAL
Vipin Zamvar
This paper describes a pericardial fold that has not yet been mentioned in the Anatomy or Surgery literature.The "Zamvar" pericardial fold is formed by the parietal pericardium and the overlying fibrous pericardium folding back onto themselves over the left-sided pulmonary veins; it is 1 to 3 mm wide, and runs from the inferior edge of the left inferior pulmonary vein, to the superior edge of the left superior pulmonary vein. A similar fold is not seen on the right side.The presence of this fold allows for the safe placement of the deep pericardial retraction suture used during off-pump coronary artery surgery...

BACKGROUND: Mechanical chest compression using a piston device during reanimation is often the only way to ensure stable chest compression at a constant rate and force. However, its use can be associated with severe fractures of the thoracic rib cage and endanger the clinical course of the patient. Thus, the usage of such a piston device during the reanimation has currently been classified as a mere Class IIB indication. CASE PRESENTATION: We present a case of a 66-year-old male who underwent emergent CABG surgery after receiving out-of-hospital resuscitation as a result of myocardial infarction using the LUCAS system...

BACKGROUND: Aortic valve replacement in a patient with an aortic homograft can be very challenging, especially when concomitant mitral valve surgery needs to be performed. CASE PRESENTATION: We report a case of implantation of a sutureless aortic valve bioprosthesis combined with mitral valve replacement in a patient with a severely calcified aortic homograft where conventional valve replacement was technically unfeasible. CONCLUSIONS: We believe that sutureless AVR is a viable option especially for young patients with a high surgical risk where conventional valve replacement cannot be achieved...

BACKGROUND: Aneurysm or pseudoaneurysm is the main vascular complication of Behcet's disease. Most hospitals adopt endovascular treatment. CASE PRESENTATION: We report a case of Behcet's disease with recurrent thoracic aortic aneurysm combined with femoral artery aneurysm. The patient underwent two rounds of endovascular surgery, but developed new aneurysms immediately after surgery. Eventually, the patient died due to rupture of recurrent aneurysm. CONCLUSIONS: For vasculo-Behcet's disease, we suggest performing the operation during the stable period...

BACKGROUND: The original 'candy-plug' technique has been reported to be beneficial for the treatment of residual perfused false lumen in patients with aortic dissection. However, this technique is also associated with several problems, such as narrowing of the true lumen and damage to the flap or vessel wall. Therefore, we modified the procedure to overcome these problems. Here we report a case in which the patient was successfully treated using the modified procedure. CASE PRESENTATION: A 59-year-old man presented with chronic type B aortic dissection with aneurysmal dilatation...
