Abstract: Background. Crush stenting mandates a final kissing-balloon technique (KBT) for a better clinical outcome; however, recrossing the 2 overlapping stent struts with the balloon catheter is technically challenging. Objectives. The efficacy of the buddy-balloon technique for facilitating completion of the final KBT during crush stenting of the left main coronary artery (LMCA) was evaluated.

Abstract: Objectives. The purpose of this study was to assess the effect of remote ischemic precondition (RIPC) on the incidence of myocardial and renal injury in patients undergoing cardiovascular interventions as measured by biomarkers. Clinical data were pooled to evaluate the usefulness of RIPC to benefit clinical outcomes. Background. Debate exists regarding the merit of using RIPC for patients undergoing cardiovascular interventions.

Abstract: Background. The current standard of care is to delay coronary surgery 5-7 days after clopidogrel exposure to prevent bleeding complications. We sought to determine the utility of an objective tool (ie, the VerifyNow assay) to measure platelet inhibition (PI) in patients receiving preoperative clopidogrel prior to off-pump coronary artery bypass grafting surgery (OPCABG). Patients and Methods. Between June 2007 and July 2009, a total of 482 isolated OPCABG procedures were performed at our institution.
Coronary Artery Bypass Graft Surgery in Patients Receiving Antiplatelet Therapy: Can We “Fine-Tune” the Balance of Safety and Efficacy?

Oral dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor, most often clopidogrel, has been demonstrated to reduce the composite risk of ischemic morbidity and mortality across a wide range of patient groups including those with acute coronary syndromes (ACS) and post-percutaneous coronary intervention (PCI).1-3
Mechanism of Edge Restenosis After Sirolimus-Eluting Stent Implantation

Abstract: Objectives. The present study evaluated the mechanism of edge restenosis after sirolimus-eluting stent (SES) implantation using serial (post-intervention and follow-up) intravascular ultrasound (IVUS) analysis. Background. There is little information about the mechanism of edge restenosis after SES implantation.
Short-Term Efficacy of Palliative Balloon Aortic Valvuloplasty in Selected Patients with High Operative Risk

Abstract: With the introduction of transcatheter aortic valve implantation (TAVI), the precise role of balloon aortic valvuloplasty (BAV) remains to be established. Methods. Between August 2008 and November 2010, consecutive patients undergoing BAV for severe aortic stenosis (AS) in our center were enrolled. The primary endpoint was survival to hospital discharge. Secondary endpoints were 30-day survival and progression to aortic valve replacement (AVR).
Old Dog, New Tricks: Redefining the Role for Balloon Aortic Valvuloplasty in the Transcatheter Aortic Valve Replacement Era

The recent publication of the Placement of Aortic Transcatheter Valves (PARTNER) trial and subsequent FDA approval of the Edwards Sapien balloon-expandable transcatheter aortic valve replacement (TAVR) system have shed new light on the treatment of aortic stenosis in patients deemed either at extreme risk (“inoperable”) or at high risk for open surgical aortic valve replacement (AVR).
Transradial Measurement of Transvalvular Pressure Gradient in the Setting of Mechanical Aortic and Mitral Valve Prostheses Using a Coronary Fractional Flow Reserve Guidewire
- Mon, 1/30/12 - 3:22pm

- 546 reads
Abstract: Accurate measurement of transvalvular pressure gradients is essential to comprehensively evaluate whether mechanical prosthetic valves are functioning normally. Direct measurements can be technically complicated, traditionally requiring direct, transapical puncture in the setting of both aortic and mitral mechanical valve prostheses.
