Background: Pregnant women with Marfan syndrome (MS) have a high risk of aortic dissection around delivery and their optimal management requires a multi-disciplinary approach, including proper cardio-obstetric care and adequate pain management during labor, which may be difficult due to the high prevalence of dural ectasia (DE) in these patients.

Objectives: To evaluate the multidisciplinary management of MS patients during labor.

Methods: Nineteen pregnant women (31 pregnancies) with MS were followed by a multi-disciplinary team (cardiologist, obstetrician, anesthesiologist) prior to delivery.

Results:. Two patients had kyphoscoliosis; none had previous spine surgery nor complaints compatible with DE. In eight pregnancies (7 patients), aortic root diameter (ARd) before pregnancy was 40 to 46 mm. In this high-risk group, one patient underwent elective termination, two underwent an urgent cesarean section (CS) under general anesthesia, and five had elective CS; two under general anesthesia (GA), and three under spinal anesthesia. In 23 pregnancies (12 patients), ARd was < 40 mm. In this non-high-risk group three pregnancies (1 patient) were electively terminated. Of the remaining 20 deliveries (11 patients), 14 were vaginal deliveries, 9 with epidural analgesia and 5 without. Six patients had a CS; four under GA and two2 under spinal anesthesia. There were no epidural placement failures and no failed responses. There were 2 cases of aortic dissection, unrelated to the anesthetic management.

Conclusions: The optimal anesthetic strategy during labor in MS patients should be decided by a multi-disciplinary team. Anesthetic complications due to DE were not encountered during neuraxial block

Background: Trans-catheter aortic valve implantation (TAVI) has emerged as a novel therapeutic approach for patients with severe tricuspid aortic stenosis (AS) not suitable for aortic valve replacement.

Objectives: To describe our initial single-center experience with TAVI in patients with "off-label" indications.

Methods: Between August 2008 and December 2011 we performed TAVI in 186 patients using trans-femoral, trans-axillary, trans-apical and trans-aortic approaches. In 11 patients (5.9%) TAVI was undertaken due to: a) pure severe aortic regurgitation (AR) (n=2), b) prosthetic aortic valve (AV) failure (n=5), c) bicuspid AV stenosis (n=2), and d) prosthetic valve severe mitral regurgitation (MR) (n=2).

Results: Implantation was successful in all: six patients received a CoreValve and five patients an Edwards-Sapien valve. In-hospital mortality was 0%. Valve hemodynamics and function were excellent in all patients except for one who received an Edwards-Sapien that was inside a Mitroflow prosthetic AV and led to consistently high trans-aortic gradients. No significant residual regurgitation in AR and MR cases was observed.
Conclusions: TAVI is a good alternative to surgical AV replacement in high risk or inoperable patients with severe AS. TAVI for non-classical indications such as pure AR, bicuspid AV, and failed prosthetic aortic and mitral valves is feasible and safe and may be considered in selected patients.
