Saphenous vein graft percutaneous coronary intervention via radial artery access: safe and effective with reduced hospital length of stay.
Although percutaneous coronary intervention (PCI) via radial artery access confers many advantages over the femoral artery, PCI to saphenous vein grafts (SVG) is commonly performed via the femoral route. We compared outcomes in patients undergoing SVG PCI from the radial and femoral routes. ⋯ Saphenous vein graft PCI can be safely and effectively performed via radial artery access with comparable fluoroscopy times but not radiation doses. Of clinical significance, use of the radial artery access was associated with decreased hospital stay and arterial complications. These data suggest that a routine radial approach for SVG PCI is feasible and could offer clinical and economic benefits.

Comparative StudyAortic annulus area assessment by multidetector computed tomography for predicting paravalvular regurgitation in patients undergoing balloon-expandable transcatheter aortic valve implantation: a comparison with transthoracic and transesophageal echocardiography.
Transcatheter aortic valve implantation (TAVI) is a valid alternative to surgery in high-risk patients with severe aortic stenosis. Aortic annulus (AoA) sizing is crucial for TAVI success. The aim of the study was to compare AoA dimensions measured by multidetector computed tomography (MDCT) vs those obtained with transthoracic (TTE) and transesophageal echocardiography (TEE) for predicting paravalvular aortic regurgitation (PVR) after TAVI. ⋯ Mismatch between prosthesis area and AoA area detected by MDCT is a better predictor of PVR as compared with echocardiography mismatch. Specific MDCT-based sizing recommendations should be developed.

Burden of atrial fibrillation and poor rate control detected by continuous monitoring and the risk for heart failure hospitalization.
Atrial fibrillation (AF) on electrocardiogram has been identified as a risk factor for hospitalizations in patients with heart failure (HF). We investigated whether continuous AF monitoring can identify when patients with HF are at risk for hospitalization. ⋯ Evaluation of AFb and rate control information on a monthly basis can identify patients at risk for HF hospitalization in the next 30 days.

Regionalization of post-cardiac arrest care: implementation of a cardiac resuscitation center.
Guidelines recommend standardized treatment of post-cardiac arrest patients to improve outcomes. However, the infrastructure, resources, and personnel required to meet the complex needs of cardiac arrest victims remain a barrier to care. Given that regionalization of time-dependent high-acuity illness is an emerging paradigm, the aim of the present study was to develop and implement a regionalized approach to post-cardiac arrest care. ⋯ Development of a regionalized approach to post-cardiac arrest care using previously established referral relationships is feasible, and implementation of such an approach was clinically effective in our region.

Controlled Clinical TrialImpact of access site selection and operator expertise on radiation exposure; a controlled prospective study.
Published data relating to arterial access site selection and radiation exposure during coronary procedures suggest radial access may lead to increased radiation exposure, but this is based on poorly controlled studies. We sought to measure radiation exposure to patients and operators during elective coronary angiography (CA) according to access site, with other procedure related variables controlled for. We also investigated the specific effect of operator expertise in relation to radiation exposure. ⋯ The use of TR access has no adverse effect on radiation exposure or FT for diagnostic CA, but does allow for quicker ambulation compared to TF access. The magnitude of radiation exposure is related to operator expertise for both access sites. The results of previous studies reflect the effect of uncontrolled patient and operator variables and not access site selection.
