There are several strategies of surgical approach for the repair of multiple muscular ventricular septal defects (mVSDs), but none leads to a fully predictable, satisfactory therapeutic outcome in infants. We followed a concept of treating multiple mVSDs consisting of a hybrid approach based on intraoperative perventricular implantation of occluding devices. In this report, we describe a 2-step procedure consisting of a final hybrid approach for multiple mVSDs in the infant following initial coarctation repair with pulmonary artery banding in the newborn. At 7 months, sternotomy and debanding were performed, the right ventricle was punctured under transesophageal echocardiographic guidance, and the 8-mm device was implanted into the septal defect. Color Doppler echocardiography results showed complete closure of all VSDs by 11 months after surgery, probably via a mechanism of a localized inflammatory response reaction, ventricular septum growth, and implant endothelization.

Introduction: 3D color Doppler allows a direct measurement of Vena Contracta (VC) area in patients with mitral regurgitation (MR), without the need for geometric assumptions. Hypothesis: 3D color Doppler VC area provides a more accurate assessment of MR severity than the conventional 2D color Doppler VC diameter. Methods: Patients with ≥ mild MR underwent 2D and 3D color Doppler and a quantitative echo-Doppler study. 2D VC diameter was measured from a zoomed parasternal long-axis view. 3D VC area was acquired using real-time 3D (Philips) and measured off-line (TomTec). MR severity was assessed both quantitatively, as effective regurgitant orifice area from pulsed Doppler [EROA = (mitral stroke volume - aortic stroke volume)/MR time velocity integral], and semi-quantitatively as recommended by the American Society of Echocardiography. Results: 61 patients (65 ± 15 years) were studied. MR severity was mild in 25%, moderate in 36%, and moderate to severe or severe in 39%. Mitral valve pathology was prolapse in 33%, restricted closure in 44% and annular calcification in 7%. Regurgitant MR jet was eccentric in 49% of patients. For all patients, 3D VC area correlated significantly with EROA, better than 2D VC diameter (figure ). The advantage of 3D VC area over 2D VC diameter was more pronounced in eccentric jets (r=0.76, p< 0.001 vs. r=0.5, p =0.006, respectively) and in moderate to severe or severe MR (r=0.65, p<0.001 vs. r =0.13, p=0.54, respectively). Conclusions : Measurement of VC area is feasible with real-time 3D and provides a simple parameter that accurately reflects MR severity, particularly in eccentric and clinically significant MR where geometric assumptions may be challenging.
