The prognostic impact of specialist cardiology input in patients admitted for heart failure and normal ejection fraction.

AIMS: Specialist cardiology care is associated with a prognostic benefit in patients with heart failure (HF) with reduced ejection fraction (HFrEF) admitted with decompensated HF. However, up to one third of patients admitted with HF and normal ejection fraction (HFnEF) do not receive specialist cardiology input. Whether this has prognostic implications is unknown. METHODS AND RESULTS: Data on patients hospitalized with HFnEF from two tertiary centres were analysed. The primary outcome measure was all-cause mortality during follow-up. The secondary outcome was in-hospital mortality. A total of 1413 patients were included in the study. Of these, 23% (n = 322) did not receive in-hospital specialist cardiology input. Patients seen by a cardiologist were less likely to have hypertension (73% vs. 79%, P = 0.03) and respiratory co-morbidities (25% vs. 31%, P = 0.02) compared with those who did not receive specialist input. Similarly, clinical presentation was more severe for those who received specialist input (New York Heart Association III/IV 83% vs. 75% respectively, P = 0.003; moderate-to-severe peripheral oedema 65% vs. 54%, P < 0.001). Medical management was similar, except for a higher use of diuretics (90% vs. 86%, P = 0.04) and a longer length of stay for patients who received specialist input (9 vs. 4 days, P < 0.001). Long-term outcomes were comparable between patients who received specialist input and those who did not. However, specialist input was independently associated with lower in-hospital mortality (hazard ratio 0.19, confidence interval 0.09-0.43, P < 0.001). CONCLUSIONS: In-hospital cardiology specialist input has no long-term prognostic advantage in patients with HFnEF but is independently associated with reduced in-hospital mortality.

Paediatric mitral valve disease - from presentation to management.

Mitral valve diseases are relatively rare in the paediatric population; however, they can cause considerable mortality and morbidity worldwide. Acquired causes are a major contributor to cardiovascular disease burden in the paediatric population. Diseases can be detected before birth, at birth, or when the child is older and presents with symptoms of advanced heart failure. Definitive management consists of surgical intervention, with mitral valve replacement being the gold standard.Conclusion: Repair has been gaining popularity; however, its outcomes require further study. Percutaneous mitral balloon valvuloplasty is an emerging technique which holds promise as a bridge to surgical treatment. The effect of these interventions on quality of life must be emphasised and requires further study. What is Known: • The epidemiology of mitral valve disease in the paediatric population - predominant causes include rheumatic disease and congenital defects.  • Mitral valve repair and replacement are the standard treatment methods for paediatric mitral valve disease.  What is New: • Emergence of percutaneous mitral valve interventions and their potential as bridge-to-surgery or definitive treatment in high-risk surgical candidates.  • Recent evidence comparing mitral valve repair and replacement in the paediatric population demonstrates increasing popularity of repair techniques.
