We were unable to validate the rFI as a predictor of complications. We developed a novel model with discrimination at least equal to other published risk models. However, there is an unmet need for well-validated, clinically useful risk tools in this area.

This study evaluated the safety and efficacy of orbital atherectomy (OA) for the treatment of severely calcified coronary artery bifurcation lesions.

Percutaneous coronary intervention (PCI) of severely calcified coronary artery lesions is associated with lower procedural success and higher rates of target lesion failure compared to non-calcified lesions. OA is an effective treatment for calcified coronary artery lesions prior to stent implantation. However, there is little data regarding the safety and efficacy of OA in patients with coronary artery bifurcation lesions.

Data were obtained from analysis of patients with severe coronary artery calcification who underwent OA and coronary stent implantation at ten high-volume institutions. Data were pooled and analyzed to assess peri-procedural outcomes and 30-day major adverse cardiac events (MACE).

A total of 1156 patients were treated with OA and PCI. 363 lesions were at a coronary artery bifurcation. There were no statistically significant differenceifurcation and non-bifurcation locations.

Patient BMI is associated with radiation doses received by interventional cardiologists, yet the association between patient BMI and nurse radiation doses is unknown. This study evaluated the association between patient body mass index (BMI) and nurse radiation doses during coronary angiography.

Nurse radiation doses were collected by real-time dosimeters during consecutive coronary angiography procedures and are reported as the personal dose equivalent (H

10). Patient radiation doses were estimated using dose area product (DAP). Patient BMI was categorized in kg/m

as <25.0, 25.0-29.9, 30.0-34.9, 35.0-39.9, and ≥40. Multiple regression analysis determined procedural factors independently association with nurse radiation doses.

In 643 consecutive coronary angiography procedures, patient radiation doses increased significantly across increasing patient BMI categories (p<0.001). Compared to a patient BMI <25, a patient BMI ≥40 was associated with a 2.3-fold increase in DAP (p<0.001). Significant differences were also observed in nurse radiation doses across patient BMI categories (p=0.036). Compared to a patient BMI <25, a patient BMI ≥40 was associated with a 4.0-fold increase in nurse radiation dose (BMI<25 0.3 [0.1, 1.3] μSv; BMI≥40 1.2 [0.2, 2.9] μSv; p=0.003). By multiple regression analysis, each 1-unit kg/m

increase in patient BMI was associated with a 3.3% increase in nurse radiation dose (p=0.002).

Patient BMI was significantly associated with nurse radiation doses during coronary angiography. These observations may have important implications on nurse radiation safety, especially in the setting of the ongoing obesity epidemic.

Small vessels were defined as reference vessel diameters (RVD) ≤2.5 mm. A Cox proportional hazards model was used to identify predictors of target lesion failure (TLF) through 2 years. Patients undergoing small vessel disease PCI had a higher frequency of diabetes, prior myocardial infarction (MI), and prior PCI. 2 year TLF was higher among patients with small vessels (9.7% vs. Selleckchem Selumetinib 5.9%, HR 1.7 [95% CI 1.22-2.37], p less then 0.01), driven by increased rates of target vessel-MI and target lesion revascularization (TLR). Stent thrombosis at 2 years was higher among patients with small vessel disease (1.4% vs. 0.3%, HR 5.25 [95% CI 1.47-18.8], p less then 0.01). 2 year TLF rates were similar in the RES and ZES patient groups (Pinteraction 0.86). In conclusion, patients undergoing PCI in small vessels have significantly worse outcomes despite the use of contemporary stents.Percutaneous coronary intervention (PCI) is one of the most frequent non-surgical procedures performed worldwide. As any invasive procedure, PCI is accompanied by a low but still important risk of complications. One such very rare complication is when the angioplasty balloon cannot be deflated. We present a case of undeflatable balloon during chronic total occlusion PCI and we report a novel technique for balloon retrieval using the Excimer light amplification by stimulated emission of radiation (Laser) coronary atherectomy device.

The objective of this study was to identify transfusion-related in-hospital outcomes in orthotopic heart transplantation (OHT) recipients.

Retrospective chart review.

Tertiary care hospital.

Adult OHT recipients undergoing transplantation between January 2010 and December 2016.

None.

The primary composite outcome was occurrence of any of the following events during admission for OHT (1) graft dysfunction requiring mechanical circulatory support (MCS); (2) respiratory failure requiring tracheostomy; (3) renal failure requiring hemodialysis; (4) 30-day mortality; (5) complication requiring readmission to intensive care unit; (6) sepsis; and (7) stroke. The authors evaluated these outcomes in relation to all blood component transfusions received intraoperatively and in the first 24 hours postoperatively. The study included 197 patients and the primary composite outcome was present in 72 (36.6%). After adjusting for propensity score, red blood cell (RBC) transfusion was associated with composite outcomes (odds ratio [OR] 1.
