Congestive heart failure in children with pneumonia and respiratory failure.

BACKGROUND: Congestive heart failure (CHF) is one of the most common cardiac complications of pneumonia in adulthood leading to increased risk of morbidity and mortality. Little is known, however, of CHF and pneumonia in children. The aim of this study was therefore to investigate the characteristics and factors associated with CHF in under-5 children with pneumonia and respiratory failure. METHODS: A retrospective cohort was conducted in hospitalized patients aged 2-59 months with community-acquired pneumonia and respiratory failure from June 2011 to June 2014 at Suratthani Hospital, Thailand. The characteristics, therapeutic strategy, and clinical outcomes of CHF were reviewed. Baseline characteristics and basic laboratory investigations on admission were compared between the CHF and non-CHF groups. RESULTS: Of 135 patients, 14 (10%) had CHF. Compared with patients without CHF, the CHF group had prolonged intubation and hospital stay and high rates of associated complications such as ventilator-associated pneumonia, sepsis, shock, and 30 day mortality. CHF was significantly associated with certain characteristics, including male sex and bacterial pneumonia. CONCLUSIONS: Pneumonia with respiratory failure is associated with CHF even in healthy children without cardiac risks. The awareness and early recognition of CHF, particularly in male, and bacterial pneumonia, is important in order to provide immediate treatment to reduce complications.

Beneficial effects of transcatheter closure of atrial septal defects not only in young adults.

OBJECTIVES: To compare cardiac events and remodeling effects after transcatheter closure of atrial septal defects (ASD) in pediatric, adult, and older adult patients. METHODS: A retrospective review was conducted of 353 patients who underwent transcatheter ASD closure between February 1999 and December 2007 at Siriraj Hospital. The patients were divided into 3 groups according to age: children (<18 years; n = 99); adults (18-50 years; n = 169); and older adults (>50 years; n = 85). Cardiac events at 1 year, and changes in left and right ventricular dimensions between preprocedure and 6 months and 1 year postprocedure were compared between groups. RESULTS: Of the 353 patients, the average size of ASD was 22.1 ± 6.6 mm. Device: ASD diameter was 1.25 ± 0.28 mm. At 1 year postprocedure, the prevalence of chest discomfort and atrial fibrillation (AF) was higher in older adult patients, compared to the other age groups. Device embolization, cardiac erosion, pericardial effusion, syncope, migraine, thrombus formation, and residual shunt did not differ between groups. Within the first 6 months, the right ventricular (RV) dimension tended to dramatically decrease, while the left ventricular (LV) dimension increased in all age groups. These changes leveled off in children and in older adults, but in the adult group (18-50 years), RV shrinkage and LV expansion continued for 1 year. A low rate of early and late complications was noted. CONCLUSION: Transcather closure of ASD can cause cardiac remodeling, regardless of the patient's age at the time of the procedure. For older adult patients, the long-term risk of AF continuation and chest discomfort is likely.

An interarterial course of anomalous coronary artery and an alternative surgical option.

An interarterial course of anomalous left main coronary artery originating from the right aortic coronary sinus of valsalva is a rare condition among anomalous aortic origin of the coronary artery. Various surgical options are available. We performed an alternative procedure, that is, mobilisation of the pulmonic root, pulmonary bifurcation, and plication of the pulmonic root adjacent to the left main coronary artery, in a 12-year-old boy. Favourable results were achieved after 43 months of follow-up.
