Abstract
Women with genetic cardiovascular diseases,or repaired congenital defects require additional monitoring during pregancy and may need planned surgical delivery of the infant. CMR is a simple, accurate multi parametric imaging techniques which provides assessment of cardiac anatomy, function and flow in the pregnant patient.
Highlights
A retrospective analysis of the cardiac and obstetric notes of 5 women was carried out to evaluate the use of Cardiovascular magnetic resonance (CMR), the need for further imaging/intervention and outcome of the pregnancy
Patients were 16-28 weeks pregnant(mean 22 weeks) at the time of imaging Previous medical history and indications for CMR were: severe aortic stenosis and bicuspid valve with syncopal episodes (1), Marfans syndrome with chest pain ?aortic dissection on trans oesophageal echo(1), aortic coarctation and increasing aortic root dimensions on trans thoracic echocardiography (1), aortic coarctation and bicuspid aortic valve, patent ductus arteriosus and ventricular septal defect presenting with chest pain (1) and investigation of a cardiac source of emboli causing ischaemic episodes in right leg (1).Imaging was carried out on a 1.5T Siemens Sonata or Avanto ( Ehrlagen, Germany) using a spine array posteriorly and 2 channel flex array placed over the anterior chest
All patients tolerated CMR- average imaging time of 25mins. 4 patients delivered at 34-37 week 3 planned caesarean sections,1 spontaneous vaginal delivery.Birth weight 2370-3076 grams.Balloon valvuloplasty was carried out within 1 week of CMR in the patient with severe aortic stenosis and surgical aortic valve replacement 3 months post delivery
