BACKGROUND: Atrioventricular nodal reentrant tachycardia (AVNRT) is a common tachyarrhythmia substrate in children, which is successfully treated by catheter ablation using radiofrequency or cryothermal energy. In recent years, cryoablation (Cryo) using electroanatomical system guidance is more commonly preferred for use in children in order to decrease the risk of an atrioventricular block. However, there are concerns regarding the long-term efficacy of Cryo in treating AVNRT. We aimed to evaluate the feasibility, safety, and long-term efficacy of Cryo for AVNRT in children...

Outcomes of hematopoietic stem cell transplantation (HSCT) have markedly improved over the past 2 decades, underscoring a need to better understand the long-term health effects of this intensive treatment modality. We describe the burden of chronic medical conditions and frail health among St. Jude Lifetime Cohort Study participants treated for childhood hematologic malignancies with HSCT (n = 112) or with conventional therapy (n = 1106). Chronic conditions and frail health were ascertained clinically and classified according to a modified version of the Common Terminology Criteria for Adverse Events (version 4...

Background: Ablation of the pulmonary vein (PV) antrum using an electroanatomic mapping system is standard of care for point-by-point pulmonary vein isolation (PVI). Focused ablation at critical areas is more likely to achieve intra-procedural PV isolation and decrease the likelihood for reconnection and recurrence of atrial fibrillation (AF). Therefore this prospective pilot study is to investigate the short-term outcome of a voltage-guided circumferential PV ablation (CPVA) strategy...

Yoshifumi Nakajima, Saibal Kar
The MitraClip (Abbott Vascular, Santa Clara, CA) procedure has emerged as a safe and effective treatment option for treatment of selected patients with severe mitral regurgitation (MR) who are at high risk for surgery. Effective reduction of MR is important to ensure an optimal clinical outcome. We present here the first case report of a significant commissural leak after a MitraClip procedure treated with a GORE CARDIOFORM Septal Occluder device (WL Gore & Associates, Flagstaff, AZ). CASE REPORT: An 81-year-old male presented with symptomatic recurrent MR following a MitraClip procedure using two clips...

REVIEW
Martin W Bergmann, Carsten W Israel
In Europe left atrial appendage occluders (LAAO) are most frequently used in patients with contraindications for oral anticoagulation (OAC); therefore, the classical therapeutic OAC scheme from the PROTECT-AF trial (vitamin K antagonist plus acetylsalicylic acid) is usually changed to dual anti-platelet therapy (DAPT) after implantation of a Watchman® or Amulet® LAAO (St. Jude Medical/Abbott, Eschborn, Germany). For many years, patients with an LAAO received DAPT for 1-6 months. The current standard comprises DAPT for 3 months, followed by permanent acetylsalicylic acid monotherapy if the transesophageal echocardiogram excludes a thrombus at the site of the LAAO...

A 53-year-old diabetic male with sternal dehiscence presented with recurrent staphylococcus bacteremia 2years after coronary artery bypass grafting (CABG). He was found to have a giant right coronary artery (RCA) pseudoaneurysm and a coronary cameral fistula on imaging. Due to excessive surgical risk, the patient underwent percutaneous treatment with a 5mm Amplatzer vascular plug 4 (St. Jude Medical, St.Paul, MN). Post-procedure imaging showed successful cessation of flow into the pseudoaneurysm and follow-up CT scan demonstrated significant improvement in the size of the pseudoaneurysm...

The temporary total artificial heart (TAH-t) has been valuable as a bridge to transplantation in patients with biventricular failure. However, the challenges of accurately assessing pulmonary vascular resistance after TAH-t implantation can preclude these patients from heart transplantation, especially those with pre-existing pulmonary hypertension. The CardioMEMS Heart Failure System (St. Jude's Medical, Little Canada, MN) comprises a wireless pressure sensor that is implanted percutaneously in the pulmonary artery and transmits real-time measurements of pulmonary artery pressures...

BACKGROUND: Some important studies have shown that patient-prosthesis mismatch is a frequent occurrence after surgical aortic valve replacement that impairs survival. The Trifecta valve (St. Jude Medical Inc, St. Paul, MN) has special architecture designed to achieve the best hemodynamic profile. The aim of this study was to determine the prevalence of mismatch when using this prosthesis. METHODS: This study included 1,302 patients at 3 months postoperatively, 339 patients with a Trifecta prosthesis and 963 patients (the control group) with a Mitroflow aortic valve (Sorin Group Inc, Mitroflow Division, Vancouver, Canada)...

INTRODUCTION: Gluteal artery aneurysms (GAAs) are rare, accounting for less than 1% of all arterial aneurysms. Most of them are post-traumatic in nature and involve the superior gluteal artery (SGA), while injuries of the inferior gluteal artery (IGA) have been reported less frequently. We report an unusual case of a patient with double saccular GAA of unknown etiology, involving both the SGA and IGA, successfully treated by endovascular embolization. CASE REPORT: A 80-year-old man referred to our hospital complaining of the progressive onset of left buttock pain and swelling exacerbated by sitting position in the last 4 months...

Left atrial appendage (LAA) closure prevents thromboembolic risk and avoids lifelong anticoagulation due to atrial fibrillation (AF). Nowadays, AtriClip, a modern epicardial device approved in June 2010, allows external and safe closure of LAA in patients undergoing cardiac surgery during other open-chest cardiac surgical procedures. Such a surgical approach and its epicardial deployment differentiates LAA closure with AtriClip from percutaneous closure techniques such as Watchman (Boston Scientific, Marlborough, MA, USA), Lariat (SentreHEART Inc...
