Effectiveness of chest physiotherapy and pulmonary rehabilitation in patients with non-cystic fibrosis bronchiectasis: a narrative review.

Respiratory physiotherapy and rehabilitation are important therapeutic options in non-cystic fibrosis bronchiectasis (NCFB). The aims of this review of clinical trials were to evaluate the safety and the effects on physiologic and clinical outcomes of airway clearance techniques (ACTs) and rehabilitation in NCFB patients, in comparison to usual care. The search was performed on March 2018 by using PubMed and PeDro databases. 33 studies were selected. The use of ACTs for NCFB were effective in increasing sputum volume although no benefit in quality of life (QoL) or pulmonary exacerbations were observed. There were no differences in effectiveness between the several techniques used. Humidification and saline inhalation were able to aid airway clearance. Hypertonic solution (HS) was more effective than isotonic solutions (IS) in improving expectoration and sputum viscosity. Pulmonary rehabilitation (PR) was found to be associated with short term benefits in exercise capacity, dyspnea and fatigue. Exercise training seems to improve quality of life and lower exacerbation rate, but long-term data are not available. Further studies are necessary to identify the most feasible long-term outcomes such as QoL and exacerbation rate

Treatment of non-restrictive cor triatriatum sinister during concomitant cardiac surgery

Abstract Background Cor triatriatum is a rare congenital heart disease representing the 0.4% of all congenital cardiac anomalies. To date, no specific genetic alteration has been associated to cor triatriatum. The left-sided presentation (cor triatriatum sinister (CTS)) generally consists in a fibromuscular membrane that divides the left atrium into two chambers, therefore generating a varying grade of flow obstruction depending on the shape, location, and membrane fenestration size. Cor triatriatum sinister can be isolated or associated to other congenital heart defects such as ostium secundum atrial septal defect, patent foramen ovale or abnormal pulmonary veins drainage. Case presentation Our case is a 63-year-old woman who was diagnosed with a non-restrictive membrane during a hospitalization for acute heart failure. In the following 6 months, she started to become symptomatic. However, the onset of symptoms was more likely related to mitral valve regurgitation worsening and previously unknown coronary artery disease, rather than to CTS. She underwent bi-atrial surgical ablation (Cox Maze IV procedure) for atrial fibrillation (AF), surgical resection of interatrial membrane with mitral annuloplasty, and myocardial revascularization. Conclusion The onset and severity of symptoms in patients with CTS mostly depend on membrane fenestration size, grade of stenosis generated and pulmonary veins drainage site. However, some cases may remain asymptomatic until adulthood; the degree of pulmonary hypertension and congestive heart failure is determined by the presence of additional cardiac anomalies and the fibromuscular membrane fenestration. In some cases, CTS may remain asymptomatic, thus the diagnosis can be incidental

Del Nido cardioplegia in adult cardiac surgery: Clinical outcomes in a single center all-comer study

Introduction: The use of Del Nido Cardioplegia (DNC) has been extended in the latest years from pediatrics to adult cardiac surgery with encouraging results. We sought to investigate clinical and biochemical outcomes in adult patients who underwent cardiac surgery with different degrees of complexity who received DNC for myocardial protection.Methods: Data on one-thousand patients were retrospectively collected from 2020 to 2022. The only exclusion criteria was off-pump adult cardiac surgery. Surgical procedures weight was categorized according EuroSCORE II in six groups: Single-CABG(G1), isolated non-CABG(mitral) (G2), isolated non-CABG(aortic) (G3), isolated non-CABG(any) (G4), 2-procedures(G5), 3/more-procedures(G6). Primary endpoint was to identify a binomial correlation between hs-TnT/CK-MB and the cross-clamp time (X-Clamp). A secondary endpoint was the comparison between the treatment groups of the vasoactive-inotropic score (VIS) and the need of mechanical circulatory support (MCS).Results: A linear correlation was identified between hs-TnT and X-clamp in the overall population (rho:0.447, p< .001) and in the treatment groups (G1:rho=0.357, p< .001/G2:rho=0.455, p< .001/G3:rho=0.307, p= .001/G4:rho=0.165, p= .257/G5:rho=0.157, p= .031/G6:rho=0.226, p= .015). Similarly, a linear correlation between CK-MB and X-clamp in the overall population (rho=0.457, p< .001) and treatment group (G1:rho=0.282, p< .001/G2:rho=0.287, p= .025/G3:rho=0.211, p= .009/G4:rho=0.0878, p= .548/G5:rho=0.309, p< .001/G6: rho=0.212, p= .024) was identified. As regard for the secondary endpoint, no differences were reported between the treatment groups in terms of VIS and MCS (VIS G1:7; G2:4; G3:7; G4:7, G5:5.5, G6:6, p-value= .691) (MCS G1: 4.5%; G2:4.8%; G3:3.3%; G4:3.1%; G5:1.4%; G6:5.3%; p-value= .372).Conclusions: Del Nido Cardioplegia is a safe and useful tool in adult cardiac surgery allowing operators to achieve a stable and durable cardioplegic arrest. Despite accounting with different types of surgery, the six subgroups of our study population showed similar perioperative results

Cinefluoroscopic identification of Bj\uf6rk-Shiley prosthetic heart valves

Numerous mechanical prostheses are currently utilized for heart valve replacement. Fluoroscopy is a useful technique to identify prosthetic valves, to evaluate their function and to follow-up the patients' condition. Scattered and contrasting data, however, have been reported about the radiographic appearance of Bj\uf6rk-Shiley heart valves. This study shows that each Bj\uf6rk-Shiley valve model has characteristic radiographic features that can be readily determined by fluoroscopic evaluation, leading to easy and accurate non-invasive identification
