Objective: Early and midterm outcomes were evaluated in patients who had postinfarction ventricular septal defect (VSD) and underwent VSD repair using the triple patch technique.
Methods: Twenty-one patients underwent VSD repair for postinfarction VSD between April 2004 and September 2015. A retrospective analysis of all in-hospital and postdischarge data was performed. In addition, we compared pre- and perioperative variables between survivors and nonsurvivors.
Results: Thirty-day mortality was 23.8% (5 patients). Three patients died due to low output syndrome and 2 patients died due to sepsis. All of these patients were in cardiogenic shock preoperatively. Although 3 patients had a small residual shunt after surgery, the residual shunt disappeared 6 months after surgery in 1 patient and has been decreasing gradually in another. The mean follow-up was 43.5 ± 36.1 months. Overall survival rates (Kaplan-Meier method) at 3 and 8 years were 70.8% and 57.9%, respectively. Compared with survivors, nonsurvivors had a higher incidence of preoperative cardiogenic shock, higher incidence of chronic kidney disease and end-organ failure, and longer aortic crossclamp times during surgery.
Conclusions: Early and midterm outcomes of modified infarct exclusion using the triple patch technique are acceptable. This technique is safe and simple, and may be useful for reducing postoperative residual shunt.

A dual-therapy sirolimus-eluting and CD34+ antibody-coated Combo Stent (DTS) has been developed to enhance endothelization and capture endothelial progenitor cells; however, vessel responses following DTS implantation remain unclear. Therefore, we evaluated early- and mid-term intravascular characteristics of DTS using intravascular imaging modalities. This multicenter, prospective, observational study enrolled 88 patients (95 lesions) who underwent DTS (43 patients, 48 lesions) or sirolimus-eluting Orsiro stent (SES, 45 patients, 47 lesions) implantation.

A type 2 endoleak (EL2) remains the most prevalent complication of endovascular aortic repair (EVAR) for an abdominal aortic aneurysm (AAA). We conducted a retrospective, single-center analysis, including patients who underwent embolization for an isolated EL2 after EVAR. The study population was stratified into two groups: Group A, consisting of patients whose EL2 resolved after the first embolization procedure, and Group B, consisting of those with refractory EL2 (rEL2).

Introduction: An effective vaccination policy must be implemented to prevent foot-and-mouth disease (FMD). However, the currently used vaccines for FMD have several limitations, including induction of humoral rather than cellular immune responses.
Methods: To overcome these shortcomings, we assessed the efficacy of levamisole, a small-molecule immunomodulator, as an adjuvant for the FMD vaccine.

Background: Patients with prior history of chest or mediastinal radiation are deemed high risk for surgical AVR. Transcatheter aortic valve replacement (TAVR) has emerged as a promising alternative for these patients, however, this patient population was underrepresented in prior TAVR trials.
Aims: To compare the outcomes of TAVR in patients with versus without a history of prior chest or mediastinal radiation.

Background: This study evaluated the midterm outcomes of rapid deployment aortic valve replacement (RDAVR) performed regardless of pathology for various aortic valve diseases at a single center.
Methods: Of the 344 patients who underwent RDAVR using Edwards INTUITY during the study period at our institution, 176 had bicuspid valve diseases (51.2%), 20 had pure aortic regurgitation (5.
