Audio

Description

In this episode, CardioNerds (Amit Goyal), Cardio-OB series co-chair and UT Southwestern cardiology fellow, Dr. Sonia Shah, and episode lead fellow, Dr. Laurie Femnou (UT Southwestern) are joined by Dr. Michael Luna (UT Southwestern) to discuss cardiovascular interventions during pregnancy. We discuss practical considerations for performing coronary angiography and valvular interventions in the pregnant patient, the timing and indication of procedures, and ways to minimize radiation exposure to both mom and baby.

Pearls- Cardiac Interventions during Pregnancy Attempt should be made to manage pregnant patients with valvular disease with medical therapy, and cardiac interventions during pregnancy should be considered a last resort.Ideally, procedures in the gravid patient should be performed after 20 weeks gestation to minimize fetal risk. Specific ways to minimize radiation to the pregnant patient and fetus in the catheterization lab include: using an abdominal shield, radial access for coronary procedures, proper positioning of the C-arm to avoid extreme angulation, using collimation, and minimizing fluoroscopic time, frame rate, and use of cine-acquisition. When appropriate, intracoronary imaging modalities (ie. IVUS or OCT) should also be considered.Fetal monitoring should be performed during any cardiac intervention in the pregnant patientMultidisciplinary involvement and contingency planning are critical for the success of any high-risk cardiac intervention in the pregnant patient. Quatables - Cardiac Interventions during Pregnancy “Meetings including all providers— our cardiac surgical colleagues, cardiac anesthesiologists, and our obstetrics team—in the care of [pregnant] patients has to be had well ahead of a cardiac procedure to plan every detail.” Show notes - Cardiac Interventions during Pregnancy 1. What are special considerations for performing a balloon valvuloplasty in a pregnant patient with mitral stenosis? In pregnant patients with severe mitral stenosis who cannot be adequately managed with medical therapy, percutaneous balloon mitral valvuloplasty (PMBV) is the treatment of choice given the high risk of morbidity and fetal loss with cardiac surgery.Ideally, procedures in the gravid patient should be performed after 20 weeks gestation to minimize risk to the fetus. Assessment of valve anatomy and consideration of the Wilkin’s score are especially important in pregnant patients to minimize the risk of peri-procedural complications.PBMV should performed at experienced centers with cardiac surgery and MFM available.Complications of PBMV are rare but include atrial perforation, cardiac tamponade, arrhythmias, emboli, mitral regurgitation, hypotension and maternal death. Mechanical support should be readily available and a delivery strategy in place in case there is sudden maternal or fetal deterioration. 2. What are ways to minimize radiation exposure in the catheterization lab to the pregnant patient and fetus? The general principle for imaging during pregnancy is similar to imaging for the general population, with the goal of radiation exposure being as low as reasonably achievable (ALARA). The mean radiation exposure to the unshielded abdomen is 1.5 mGy, and
