Insights

Sildenafil treatment for infant pulmonary hypertension may cause side effects mimicking heart failure. Discontinuation of sildenafil led to dramatic improvement in a case of infant supracardiac total anomalous venous connection.

Area of Science:

  • Pediatric Cardiology
  • Neonatal Medicine
  • Pharmacology

Background:

  • Sildenafil is a common treatment for pulmonary hypertension in infants with congenital heart disease.
  • Observed side effects of sildenafil can resemble congestive heart failure symptoms in children.

Purpose of the Study:

  • To report a case of a two-month-old infant experiencing adverse effects attributed to sildenafil.
  • To highlight potential diagnostic challenges in differentiating drug side effects from disease progression.

Main Methods:

  • Case presentation of a two-month-old infant with supracardiac total anomalous venous connection and pulmonary hypertension.
  • Clinical observation of symptoms including severe sweating and tachycardia following sildenafil initiation.

Main Results:

  • The infant developed severe sweating and tachycardia after starting sildenafil therapy.
  • These symptoms resolved dramatically upon discontinuation of sildenafil, indicating a probable drug-related adverse event.

Conclusions:

  • Sildenafil therapy can present with side effects that mimic congestive heart failure in infants.
  • Careful monitoring and consideration of drug-induced side effects are crucial in managing pediatric patients with pulmonary hypertension.

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors

Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
