BACKGROUND: Hypoxia-inducible factor (HIF1A) regulates the myocardial response to hypoxia and hemodynamic load. We investigated the association of HIF1A variants with right-ventricular (RV) remodeling after tetralogy of Fallot (TOF) repair. METHODS: Children with TOF were genotyped for three single-nucleotide polymorphisms in HIF1A. Genotypes were analyzed for association with RV myocardial protein expression and fibrosis at complete repair (n = 42) and RV dilation, fractional area change, and freedom from pulmonary valve/conduit replacement on follow-up...

We experienced a case with acute mitral regurgitation caused by complete posterior papillary muscle rupture as complication of acute inferior myocardial infarction, who underwent successfully emergency operation of mital valve replacement and coronary revascularization in acute stage. A 64-year-old woman developed sudden cardiogenic shock shortly after the onset of acute inferior myocardial infarction. The diagnosis of acute inferior myocardial infarction was based on the electrocardiographic findings. Under IABP support, preoperative coronary angiography visualized total occlusion of segment 3 of the right coronary artery, and preoperative left ventriculography showed akinesis of inferior wall and severe mitral regurgitation...

In this paper we report on our early results of minimally invasive cardiac valve surgery. A series of 6 consecutive patients with valvular disease underwent valve repair and valve replacement via a right parasternal incision; aortic valve replacement 3, mitral valve replacement 1, mitral valve repair 2. There were no intraoperative complications requiring median sternotomy. Five patients had no blood transfusion. There was only one postoperative event; this patient had a sudden massive bleeding from the chest tube after extubation of the endotracheal tube, an immediate re-suture of the aortotomy was performed...
