Intraventricular reentry has been prooved by pre-operative electrophysiological studies in two patients without coronary artery disease and resistant ventricular tachycardia. A simple ventriculotomy oriented by epicardial mapping during tachycardia was successfull with a background of 9 and 14 months respectively. In addition, delayed epicardial potentials put into evidence an intraventricular reentry in human myocardium. This new method holds promises for the treatment of some resistant ventricular tachycardia.

Extended Sandwich Patch Technique via Right Ventriculotomy for Acute Ventricular Septal Rupture.
Ann Thorac Surg

Division of Cardiovascular Surgery, Shiga University of Medical Science, Otsu, Japan.
Background: Surgical repair for postinfarction ventricular septal rupture (VSR) was still a challenging operation, especially when required in the acute phase or posterior VSR. The extended sandwich patch technique is characterized by large double patches fixed by circumferential transmural large mattress sutures via right ventricle incision. In the present study, we report early and midterm clinical and echocardiographic outcomes of this technique.

As the indications for implanting left ventricular assist devices have expanded, some patients are qualifying for device removal after myocardial recovery. Whereas explantation has been described for previous generations of devices, no standard procedures have been developed. Removal of centrifugal-flow devices has created the need for a plug to seal the apical ventriculotomy after pump removal.

A 72-year-old diabetic man was diagnosed with acute myocardial infarction of the anterior wall and underwent emergency off-pump coronary artery bypass grafting. He was diagnosed with ventricular septal perforation(VSP) 3 days after the operation. We urgently performed surgical repair of VSP with "extended sandwich patch technique through right ventriculotomy".

Background: Single ventricle patients with unrestrictive pulmonary blood flow and (potential) subaortic stenosis are challenging to manage and optimal surgical strategy is unknown. Direct relief of subaortic stenosis by enlargement of the ventricular septal defect and/or subaortic chamber has generally been replaced by a Damus-Kaye-Stansel or Norwood procedure due to concerns of iatrogenic heart block, reobstruction, or ventricular dysfunction. Studies reporting long-term outcome after the direct approach are limited.

Objectives: To describe acute and mid-term results of hybrid perventricular device closure of muscular ventricular septal defects (mVSDs).
Background: Perventricular device closure of mVSDs can mitigate technical limitations of percutaneous closure and need for cardiopulmonary bypass or ventriculotomy with a surgical approach.
Methods: This is a multicenter retrospective cohort study of patients undergoing hybrid perventricular mVSD device closure from 1/2004 to 1/2014.
