Abstract: Patients in whom femoral arterial access is not feasible pose a challenge in terms of hemodynamic support during high-risk percutaneous coronary intervention. Patient’s height adds another challenge given the fixed lengths of available intr…
Abstract: In-stent restenosis has been a longstanding problem after percutaneous coronary intervention. The introduction of the drug-eluting stent (DES) successfully reduced the rate of restenosis; however, it is not completely diminished. Although r…
Abstract: Background. Transcatheter aortic valve implantation (TAVI) has been performed at Waikato Hospital for high-risk severe symptomatic aortic stenosis patients who are considered unsuitable for conventional cardiac surgery for the last 3 years.…
Abstract: Transfemoral aortic valve implantation has become an important interventional technique for patients with severe aortic stenosis and high surgical risks. The mitral valve has been a much greater challenge for interventional procedures, and…
Abstract: Background. Percutaneous device closure is a therapeutic option in patients with presumed stroke complicating paradoxical emboli. Newer devices with lower profiles and potentially reduced thrombogenicity have emerged, such as the Premere PF…
Abstract: Background. Although several types of distal embolic protection devices have been developed, they are usually difficult to use because of their stiff and bulky characteristics. We present a novel method to deliver the coronary embolic prote…
There has been tremendous evolution in drug and device therapy for percutaneous coronary intervention (PCI) since its inception more than 3 decades ago. Although direct thrombin inhibitors, and to a lesser extent low molecular weight heparin, have ea…
Abstract: Background. Full therapeutic heparin doses ranging from 5000-10,000 units or weight based (70-100 units/kg) have been recommended during percutaneous coronary interventions. However, there are currently no data available in regards to the a…
Abstract: Introduction. Drug-coated balloons (DCB) are being increasingly used in interventional cardiology and are established for the treatment of in-stent restenosis (ISR). It is unclear how effective they are in patients with de novo lesions. Met…
Abstract: Background. The Amplatzer Vascular Plug (AVP) I and AVP II have been used successfully to occlude moderate-large venous collateral vessels (VC) and pulmonary arteriovenous malformations (PAVM) in children and adults with congenital heart di…
