Medical ConditionsCardiac & respiratory: Congestive heart failure
Congestive heart failure
Overview
Board takeaway: Decompensated heart failure stops elective dental care; stable patients need a plan based on function, medication, and the underlying cardiac lesion.
What causes heart failure in children?
Structural or functional cardiac disease prevents adequate circulation or causes congestion. Congenital defects, cardiomyopathy, myocarditis, arrhythmia, and systemic disease can contribute. Cancer therapy, severe anemia, or endocrine and renal disease may be relevant in an individual child.
Which findings suggest worsening pediatric heart failure?
- Infants: sweating or fatigue with feeds, tachypnea, poor weight gain, and irritability.
- Older children: reduced exercise tolerance, dyspnea, fatigue, palpitations, or abdominal symptoms.
- Examination: tachycardia, gallop rhythm, poor perfusion, pulmonary congestion, edema, or hepatomegaly.
New respiratory distress, syncope, altered responsiveness, or poor perfusion requires urgent medical assessment.
What oral issues can accompany heart failure and its treatment?
Dry mouth and other medication effects, high-calorie supplements, and difficulty maintaining hygiene can increase disease risk. Anticoagulant treatment can increase bleeding. Infection control before cardiac surgery or transplantation may be especially important. These risks require assessment rather than assuming a uniform oral phenotype.
How should dental treatment be planned for a child with heart failure?
- Confirm stability with cardiology: current function, symptoms, baseline oxygenation, devices, medications, and proposed procedure.
- Defer elective care if decompensated: coordinate urgent dental needs in a medically supported setting.
- Reduce physiologic stress: good analgesia, tolerable appointments, comfortable positioning, and monitoring appropriate to risk.
- Review interactions: cardiac drugs, anticoagulants, antibiotics, and sedatives; do not interrupt prescribed medication independently.
- Clarify prophylaxis: underlying high-risk lesion or repair status controls the indication; a pacemaker alone does not.
How are heart failure and long-term prognosis managed?
Medical therapy, correction of structural disease, rhythm treatment, circulatory support, or transplantation may be needed. Prognosis varies with cause and response. A successful intervention does not eliminate the need to reassess current function before future dental treatment.
