Objective: There is a well‐known relationship between oral hygiene and infective endocarditis. Epidemiological evidence regarding perioperative oral management (POM) for cancer surgery has been accumulated, but this evidence is not sufficient for cardiac surgery. Therefore, our purpose was to investigate whether POM can prevent postoperative complications in patients undergoing heart valve surgery. Subjects and Methods: Using single‐arm medical information, we retrospectively enrolled 301 patients who underwent heart valve surgery between April 2010 and March 2019. The patient background was adjusted by the propensity score (PS). We then analyzed the impact of POM on postoperative bloodstream infection (PBSI), postoperative pneumonia, and mortality using PS inverse probability of treatment weighting (IPTW). Results: IPTW revealed that the POM group had a lower incidence of PBSI than the control group, with an odds ratio of 0.316 (p = 0.003). The mortality in the POM group was significantly lower than that in the control group (p = 0.023). Fourteen patients died in the present study and 6 of them were infection‐related. Conclusions: POM was significantly associated with decreased incidence of PBSI and mortality. The results suggest that POM is beneficial for the prevention of PBSI and mortality in patients undergoing heart valve surgery. [ABSTRACT FROM AUTHOR]

Aim: We aimed to validate the incidence of, risk factors for, and postoperative outcomes of acute kidney injury (AKI) according to the modified Kidney Disease Improving Global Outcomes (m‐KDIGO) criteria and compare this criteria with both the paediatric Risk, Injury, Failure, Loss, End‐stage disease (pRIFLE) and Acute Kidney Injury Network (AKIN) criteria in infants after cardiac surgery. Methods: We retrospectively enrolled 145 consecutive infants who underwent open‐heart surgery at Kagoshima University Hospital. Results: Acute kidney injury was present in 55 (37.9%), 111 (75.9%), and 95 (65.5%) patients according to the m‐KDIGO, pRIFLE, and AKIN criteria, respectively. Among these, 71.9% of patients pRIFLE Risk patients and 60.5% of AKIN 1 patients were categorized in the 'no‐AKI' group according to the m‐KDIGO criteria. Low body weight (m‐KDIGO odds ratio [OR], 0.73; P = 0.015; pRIFLE OR, 0.66; P = 0.001; AKIN OR 0.69, P = 0.002) and prolonged cross‐clamp time (m‐KDIGO OR, 1.02;

We implanted a permanent transvenous pacemaker to a patient with d-transposition of the great arteries (TGA) 22 years after the Mustard procedure. The patient was a 23-year-old male who had undergone the Mustard procedure at one year of age. Although he was asymptomatic during regular follow-up at our outpatient clinic until the last visit 3 months earlier, advanced atrioventricular (AV) block with sporadic complete AV block was observed. He underwent transvenous pacemaker implantation after venography for confirmation of anatomical relationship of cardiac chambers and absence of venous stenosis. The ventricular lead was anchored at the left ventricular apex, and the atrial lead was anchored at left atrial roof to avoid phrenic nerve stimulation. Screw-in leads were selected for reliable fixation. A pacemaker with a more physiological rate response function with dual sensors was selected for the bradyarrythmia. The patient was able to resume his active daily life. [Copyright &y& Elsevier]

Background: Adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) was reported to promote better coronary and myocardial reperfusion. However, long-term mortality benefit of TA remains controversial. The objective of this study is to investigate the clinical impact of TA on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI., Methods and Results: The CREDO-Kyoto AMI Registry is a large-scale cohort study of acute myocardial infarction patients undergoing coronary revascularization in 2005-2007 at 26 hospitals in Japan. Among 5429 patients enrolled in the registry, the current study population consisted of 3536 patients who arrived at the hospital within 12 hours after the symptom onset and underwent primary PCI. Clinical outcomes were compared between the 2 patient groups with or without TA. During primary PCI procedures, 2239 out of 3536 (63%) patients underwent TA (TA group). The cumulative 5-year incidence of all-cause death was significantly lower in the TA group than in the non-TA group (18.5% versus 23.9%, log-rank P<0.001). After adjusting for confounders, however, the risk for all-cause death in the TA group was not significantly lower than that in the non-TA group (hazard ratio: 0.90, 95% CI: 0.76 to 1.06, P=0.21). The adjusted risks for cardiac death, myocardial infarction, stroke, and target-lesion revascularization were also not significantly different between the 2 groups., Conclusions: Adjunctive TA during primary PCI was not associated with better 5-year mortality in STEMI patients., (© 2015 The Authors.

Objective: In a total cavopulmonary connection (TCPC) with an extracardiac conduit, the future development of stenosis in the venous pathway and distortion of the pulmonary artery according to the somatic growth of the patients is a major concern for surgeons and pediatricians., Methods: Thirty patients who underwent extracardiac TCPC (EC-TCPC) between 1990 and 1998 and who had received at least two postoperative angiograms were enrolled in this study. To evaluate the postoperative change in the anastomosis, the cross-sectional area of the venous root at three different points was measured on the first and second angiograms after the EC-TCPC. Further, to evaluate the somatic growth of the autologous tissue, 12 patients who grew more than 10 cm in height after the completion of the EC-TCPC were selected among the 30 patients. We measured the length of three different parts, the diameter of the pulmonary artery, length of the artificial graft, and length between the branching point of the hepatic vein and artificial graft's anastomotic site to the inferior vena cava., Results: The cross-sectional area at each point did not change during the follow-up, and the pressure gradient across the grafts has not been observed. The diameter of the pulmonary artery and length of the inferior vena cava above the hepatic vein insertion grew similarly during the follow-up., Conclusions: The mid-term clinical results after the completion of the EC-TCPC, including the somatic growth of the venous pathway, were satisfactory.
