[Calcification of the tricuspid annulus]
Insights
Tricuspid annular calcification, a rare condition, was observed in a woman with pulmonary stenosis. This finding, though palpable during surgery, did not affect heart valve function, suggesting a link to right ventricular hypertension.
Area of Science:
- Cardiology
- Valvular Heart Disease
Background:
- Tricuspid annular calcification (TAC) is a rare finding, particularly in younger individuals.
- Congenital valvular pulmonary stenosis can lead to right ventricular hypertension.
Observation:
- A 50-year-old woman with congenital valvular pulmonary stenosis presented with TAC identified during cardiac screening and confirmed by angiography.
- Intraoperative palpation confirmed TAC, but it did not impede tricuspid valve function.
- The patient had normal phosphate and calcium metabolism and no other associated disease processes.
Findings:
- This case represents one of only eight reported instances of TAC in patients aged 42-51.
- All reported cases, including this one, were associated with right ventricular hypertension, typically secondary to pulmonary stenosis.
- Tricuspid valve function remained normal in all documented cases of TAC.
Implications:
- TAC is a rare condition that may be linked to premature degenerative processes exacerbated by right ventricular hypertension.
- This case highlights the importance of considering TAC in patients with pulmonary stenosis, even without apparent valvular dysfunction.
- Further research into the pathogenesis of TAC is warranted, especially concerning its association with right ventricular pressure overload.
Abstract:
Tricuspid annular calcification was observed on cardiac screening of a 50 year old woman with congenital valvular pulmonary stenosis and confirmed by angiography. At operation, the tricuspid annular calcification was palpable but there was no interference with valvular function. There was no associated disease process in this patient. Phosphate and calcium metabolism was normal. Tricuspid annular calcification is very rare: 7 other reported cases, aged 42 to 51 years old. All patients had right ventricular hypertension usually caused by pulmonary stenosis. Tricuspid valve function was normal in all cases. The pathogenesis is discussed: a premature degenerative process favored by right ventricular hypertension may be responsible. This would appear to be the first case to be published in France.
