Introduction: Development of pulmonary insufficiency in patients with surgically corrected tetralogy of Fallot (TOF) may lead to severe right heart failure with serious consequences. We herein present our experience with pulmonary valve replacement (PVR) in these patients. Methods: From 2005-2013, 99 consecutive patients (71 males/28 females, mean age 38±8 years), underwent PVR after 7 to 40 (mean 29 ± 8) years from the initial correction. Seventy nine of the symptomatic patients presented in NYHA II, 14 in III and 2 in IV...

BACKGROUND: Various conduits and stent-mounted valves are used as pulmonary valve graft tissues for right ventricular outflow tract reconstruction with good hemodynamic results. Valve replacement carries an increased risk of infective endocarditis (IE). Recent observations have increased awareness of the risk of IE after transcatheter implantation of a stent-mounted bovine jugular vein valve. This study focused on the susceptibility of graft tissue surfaces to bacterial adherence as a potential risk factor for subsequent IE...

Trifecta valve is a 3rd-generation, stented bioprosthesis which is made from one bovine pericardial sheet. A 77-years-old male patient had undergone combine aortic valve replacement (AVR) using a 23-mm Trifecta valve and ascending aorta replacement for severe aortic valve regurgitation and ascending aorta aneurysm. The postoperative period was uneventful. However, he presented with dyspnea on effort and severe aortic valve regurgitation 31 months after operation. Re-do AVR with a new bioprosthetic valve was performed via 2nd sternotomy...

AIMS: Patients with degraded bioprosthetic heart valves (BHV) who are not candidates for valve replacement may benefit from transcatheter valve-in-valve (VIV) therapy. However, at smaller sized surgical BHV the resultant orifice may become too narrow. To overcome this, the valve frame can be fractured by a high-pressure balloon prior to VIV. However, knowledge on fracture pressures and mechanics are prerequisites. The aim of this study is to identify the fracture pressures needed in BHV, and to describe the fracture mechanics...

Background The endovascular approach has become a mainstay in the treatment of aortic aneurysms. While the transfemoral approach is most commonly used, it is often inaccessible due to a vascular pathology, such as occlusion, tortuosity or heavy calcifications. The transapical access provides an alternative approach. The goal of this study is to report the feasibility of the transapical approach for total endovascular repair of thoracic aortic aneurysms (TEVAR). Methods Three patients with thoracic aortic aneurysms with inaccessible femoral arteries underwent TEVAR via the transapical approach...

We report a patient with an important scenario that may arise in the management of an acute ischemic stroke: the need for a repeated mechanical thrombectomy in the same intracranial artery segment. The patient had a history of atrial fibrillation and a mechanical mitral valve replacement. In her first stroke, she had an occlusion of the proximal segment of the right middle cerebral artery; 58 days later, she presented with an occlusion in the same segment of that cerebral artery. In both instances, the thrombus was extracted by a stent retriever with good clinical and radiographic results...

Brian A Scansen
Interventional cardiology in veterinary medicine continues to expand beyond the standard 3 procedures of patent ductus arteriosus occlusion, balloon pulmonary valvuloplasty, and transvenous pacing. Opportunities for fellowship training; advances in equipment, including high-resolution digital fluoroscopy, real-time 3-dimensional transesophageal echocardiography, fusion imaging, and rotational angiography; ultrasound-guided access and vascular closure devices; and refinement of techniques, including cutting and high-pressure ballooning, intracardiac and intravascular stent implantation, septal defect occlusion, transcatheter valve implantation, and hybrid approaches, are likely to transform the field over the next decade...

Tetralogy of Fallot with absent pulmonary valve syndrome (TOF/APV) is a rare congenital malformation. Although pulmonary artery (PA) anomalies have been observed in TOF, its association with disconnected PA is extremely rare. We report successful stenting of the disconnected left PA in a 3-year-old boy with TOF/APV followed by surgical reimplantation. The significance of this transcatheter intervention for guidance during surgery and the importance of visualizing a ductal stump on angiography as an indicator of disconnected PA are discussed...

Embolic events from infective endocarditis can cause acute coronary syndrome. Mortality rate is high and optimal management might be different from those chosen in setting of classic atherosclerotic coronary artery disease. We present a case of 56-year-old male who had received 5 weeks of antibiotics for aortic valve endocarditis and developed acute ST segment elevation myocardial infarction in hospital settings. Interestingly, patient had recent left heart catheterization that was normal. This was recognized as embolic event from sterile vegetation...

AIMS: Self-expanding (SE) valves are characterized with long stent frame design and the radial force of the device exists both in the inflow and outflow level. Therefore, we hypothesized that device success of SE-valves may be influenced by ascending aortic dimensions (AAD). The aim of this study was to determine the influence of AAD on acute device success rates following SE transcatheter aortic valve replacement (TAVR). METHODS & RESULTS: In 4 centers in the United States and Asia, 214 consecutive patients underwent SE-TAVR...
