Abstract

During pregnancy BMV is feasible, safe and effective. Maternal and fetal outcomes are excellent. Growth and milestone of development are not affected.

Case Scenario: Cesarean Section Complicated by Rheumatic Mitral Stenosis

“…7,28,30 An echocardiographic score developed by Wilkins et al 30 is used to select patients who may be appropriate candidates. Four variables of mitral valve morphology are assessed, as shown in table 4.…”

The Diagnosis and Management of Chronic Rheumatic Heart Disease—An Australian Guideline

“…The safety of this procedure in pregnancy has been well established in more than 250 patients. 85 Cardiac surgery should be avoided because of the 30% foetal loss that occurs with cardiopulmonary bypass. 83 There is a small risk of traumatic mitral regurgitation resulting from PBMV, but this can usually be managed medically, without the need for surgery until after pregnancy.…”

Valvular Heart Disease and Pregnancy

“…Most reports include patients at the NYHA functional class III and IV who did not respond adequately to pharmacologic therapy. The procedure was performed in most cases at the end of the second trimester or the start of the third trimester, and in the majority of reported cases, hemodynamic and symp- (29,31,35,39,40). In addition, PBMV is associated with some risk to the fetus secondary to unavoidable ionizing radiation (41).…”
