Case ReportsResection of left ventricular papillary fibroelastoma through thoracoscopic-assisted minithoracotomy.
Although a mobile papillary fibroelastoma in the left ventricle should be excised to prevent systemic embolism, difficulties in surgical exposure of a left ventricular mass are not uncommon. Herein, we report a minimally invasive approach for resecting left ventricular papillary fibroelastoma using thoracoscopic assistance.

ReviewIs it ever worth contemplating an aortic valve replacement on patients with low gradient severe aortic stenosis but poor left ventricular function with no contractile reserve?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is worth performing aortic valve replacement in patients with severe aortic stenosis and poor left ventricular function but no contractile reserve on dobutamine stress testing. Altogether 251 papers were identified using the below mentioned search and all major international guidelines were included. ⋯ Thus, absence of contractile reserve on stress testing does not exclude myocardial recovery after surgery, although it is a strong predictor for operative mortality. It should be noted that surgery has only been reported in very few of these patients to date. B-natriuretic peptide has also been suggested as a further marker of better prognosis in these high-risk patients in one small study.

ReviewIs incentive spirometry effective following thoracic surgery?
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether incentive spirometry is a useful intervention for patients after thoracic surgery. Altogether 255 papers were found using the reported search, of which seven represented the best evidence to answer the clinical question. ⋯ We conclude that incentive spirometry is a relatively good measure of lung function and may be used to assess respiratory recovery in the days after thoracic surgery. Physiotherapy either with or without incentive spirometry reduces the incidence of postoperative complications and improves lung function but there is currently no evidence that incentive spirometry in itself could either replace or significantly augment the work of the physiotherapists. Clinicians should be aware that while incentive spirometry can provide an assessment of lung recovery, well-organised and regular physiotherapy remains the most effective mechanism to augment their patient's recovery and avoid postoperative complications.

Propranolol: a new indication for an old drug in preventing postoperative junctional ectopic tachycardia after surgical repair of tetralogy of Fallot.
Junctional ectopic tachycardia (JET) is a major cause of postoperative morbidity after complete repair of tetralogy of Fallot (TOF). Propranolol is a known medication used in patients with TOF to prevent and control hypercyanotic spells. Despite this, there is little information regarding the relation between preoperative use of propranolol and the incidence of postoperative JET. ⋯ The propranolol group had significantly less mechanical ventilation time, less ICU stay and less total hospital stay than the control group (P<0.05). Our findings suggest that the preoperative use of propranolol may decrease the incidence of JET after full surgical repair of TOF. A prospective randomized study may help to elucidate the exact relationship between the preoperative use of propranolol and the incidence of postoperative JET.

Clinical TrialDelayed recovery of human leukocyte antigen-DR expression after cardiac surgery with early non-lethal postoperative complications: only an epiphenomenon?
HLA-DR expression on peripheral blood monocytes is reduced after cardiac surgery. Little is known about the reconstitution of HLA-DR expression on peripheral blood monocytes in patients suffering from early non-fatal perioperative complications. We conducted a prospective study to prove whether these complications adversely affect the recovery of HLA-DR expression. ⋯ A delayed recovery of HLA-DR expression is seen in patients with early perioperative complications. These non-fatal complications appear to represent a 'second hit' resulting in a prolonged deficiency of the innate immune system. This might predispose to further infectious and septic complications.
