Purpose: The technical difficulty of performing the left ventricular apical anastomosis has limited the adoption of aortic valve bypass surgery for the treatment of aortic stenosis. We report the successful use of an automated coring and apical connector device to perform aortic valve bypass surgery.
Description: A 74-year-old man, with a history of prior coronary bypass surgery with patent grafts and a porcelain ascending aorta, presented with symptomatic critical aortic stenosis. Through a left anterolateral thoracotomy, a valved conduit was anastomosed to the descending thoracic aorta. The automated coring and apical connector insertion device was used to core a plug of apical myocardium and simultaneously insert an 18-mm apical connector into the left ventricular apex.
Evaluation: There were no procedural complications, cardiopulmonary bypass was not used, and estimated blood loss was minimal. The patient was discharged on postoperative day 5, and at 3-month follow-up demonstrated significant clinical and hemodynamic improvement.
Conclusions: The automated coring and apical connector insertion device facilitated the safe and effective performance of aortic valve bypass surgery.

When neither surgical valve replacement nor transcatheter aortic valve implantation is possible, performing an apico-aortic conduit remains a therapeutic option. This procedure has become rare and the rigid angled apical connectors usually used to facilitate ventricular anastomosis are no longer commercially available. We described the technique that we performed on a 60-year-old patient with readily available material.

Background: Although it is challenging to correct severe adult idiopathic scoliosis (ADIS) deformities, optimal results can be achieved by multiple asymmetric Ponte osteotomies with lower surgical risks. Skipping the apical instrumentation and using multiple rods and connectors may further facilitate the procedure. We named this method as "modular correction technique" (MCT).

New Co substituted malonate field-induced molecular magnets {[RbCo(cpdc)(HO)]∙6HO} () and [CsCo(cpdc)(HO)] () (where cpdc stands for cyclopropane-1,1-dicarboxylic acid dianions) were synthesized. Both compounds contain mononuclear bischelate fragments {Co(cpdc)(HO)} where the quasi-octahedral cobalt environment (CoO) is complemented by water molecules in apical positions. The alkali metal atoms play the role of connectors between the bischelate fragments to form 3D and 2D polymeric structures for and , respectively.

Background: Progressive C-shaped scoliosis with marked pelvic obliquity is common to spinal muscular atrophy (SMA). Reducing the number of procedures with effective deformity control is critical to minimize the risk of pulmonary complications. This study reports the preliminary results of magnetically controlled growing rods (MCGR) in SMA-related collapsing spine deformity.
