Clinical TrialOne-year clinical and angiographic results of hybrid coronary revascularization.
To evaluate 1-year clinical and angiographic results after hybrid coronary revascularization (HCR) combining off-pump left internal mammary artery (LIMA) grafting through an inferior J-hemisternotomy with percutaneous coronary intervention (PCI). ⋯ Angiographically controlled HCR was associated with a high repeat revascularization rate. The 1-year 98% LIMA-graft patency rate, and low risk of death and stroke, seem promising for the long-term outcome. Non-left anterior descending coronary artery lesion revascularization remains a challenge.

Altered left ventricular vortex ring formation by 4-dimensional flow magnetic resonance imaging after repair of atrioventricular septal defects.
During normal left ventricular (LV) filling, a vortex ring structure is formed distal to the left atrioventricular valve (LAVV). Vortex structures contribute to efficient flow organization. We aimed to investigate whether LAVV abnormality in patients with a corrected atrioventricular septal defect (AVSD) has an impact on vortex ring formation. ⋯ This study quantitatively shows the influence of abnormal LAVV and LV inflow on 3D vortex ring formation during LV inflow in patients with corrected AVSD, compared with healthy subjects.

The influence of a percutaneous mitral repair program on surgical mitral valve volume.
Percutaneous mitral repair with the MitraClip system (Abbott Vascular, Santa Clara, Calif) has been available in trials since 2006 and is currently approved for patients with degenerative mitral valve disease at prohibitive risk for surgery. There has been concern that novel transcatheter approaches may detract from mitral valve surgical volumes. We sought to evaluate the influence of our MitraClip program on our surgical mitral valve volumes and outcomes. ⋯ The availability of MitraClip resulted in an increase in our mitral valve referrals. Despite seeing an increase in higher risk referrals, operative mortality for mitral surgery remained excellent. Multidisciplinary evaluation, including input from experienced mitral surgeons, is necessary to have a successful percutaneous and surgical mitral valve program.
