Ipsilateral transulnar artery approach catheterizations after failure of the radial approach-Are two sheaths in the same arm safe?

AIMS: To assess the safety and feasibility of ipsilateral transulnar access (TUA) after failure of radial access (TRA), with two sheaths placed in the radial and ulnar arteries (RA and UA) in the same arm. MATERIALS AND METHODS: All consecutive patients with TUA due to inability to cross from ipsilateral TRA in the period from March 2011 until September 2020 were included in the study. We examined clinical and procedure characteristics, access site bleeding and ischemic complications and failure mode of initial TRA. Patients were assessed by duplex ultrasound post-procedure (at an average of 56 ± 31 months) and followed clinically (functional and pain assessment). RESULTS: In this period, out of 51,866 patients 112 (0.2%) had a transulnar artery approach due to inability to cross from ipsilateral radial approach. Mean age of patients was 65 ± 11 years with 44% females. Cause for crossover to ipsilateral TUA was inability to cross a RA anomaly in 107 (95%) patients, mostly due to the presence of a "360°" RA loop in 88 patients. Type 3 and 4 EASY Score hematoma was present in 3 patients (2.6%). Six (5.3%) of the patients had new ipsilateral radial artery occlusion noted on duplex on follow up. There were no ulnar artery occlusions detected. There were no clinical or ischemic hand complications seen during a median 4.3 years of follow up. CONCLUSION: Ipsilateral transulnar artery access following failed radial artery access crossing is safe and successful for coronary angiography and intervention with low rates of complications.

Benefit of routine preprocedural radial artery angiography in STEMI patients.

AIMS: To assess the benefit of routine preprocedural radial artery (RA) angiography in patients with ST segment elevation myocardial infarction (STEMI). METHODS AND RESULTS: All consecutive STEMI patients, in the period from January 2010 until December 2016 were included in the study. Preprocedural radial artery angiography was performed in all patients since March 2011. We compared clinical and procedure characteristics, access site bleeding complications and failure of primary chosen TRA between two groups of STEMI patients before and after we started performing routine RA angiography. We compared 762 STEMI patients from 2010 until March 2011 and 4306 STEMI patients after March 2011 until December 2016. Mean age of patients was 60 ± 11 years with 73% males. The latter group had more elderly and obese patients (P < .0001 both). Prior percutaneous coronary interventions was present in 7% of patients and 0, 1% had prior coronary bypass surgery. Procedure duration (38 ± 16 vs. 32 ± 20 min) was significantly longer in the first group (P value < .0001), but contrast volume (120 ± 33 vs. 110 ± 35 ml), and fluoroscopy time (8.6 ± 6 vs. 8.7 ± 8 min) were similar in both groups. Access crossover from primary TRA was 4, 6% in the first group, with a significant decrease to 3, 1% in the second (P < .0001), after introducing preprocedural RA angiography. Access site bleeding complications were significantly higher in the first group 6.8% vs. 4.3% in the second (p < .0001). CONCLUSION: Routine preprocedural radial artery angiography in STEMI patients is associated with lower rate of access site bleeding complications and reduced overall procedural time and TRA crossover rate.

Macedonia: coronary and structural heart interventions from 2010 to 2015.

The aim of this report is to describe invasive cardiology procedural practice in Macedonia during the period from 2010 to 2015. Details of all consecutive 39,899 patients who underwent cardiovascular, peripheral or structural heart procedures during the period from 2010 until 2015 were examined. Clinical and procedure characteristics, access site, procedural success and complications were analysed. The number of coronary angiographies increased from 5,540 in 2010 to 8,550 in 2015. Transfemoral access (TFA) was present in 4% of coronary angiographies in 2010 and had decreased to 1% in 2015. The number of primary percutaneous coronary interventions (PCI) for acute ST-segment elevation myocardial infarction increased from 763 to 1,175 and both chronic total occlusion and left main coronary artery interventions also increased over time. In 2015, the drug-eluting stent penetration rate was 65%. Structural heart interventions, including transcatheter aortic valve implantations (TAVI) were introduced in 2014 and 23 TAVI cases have since been performed. Transradial access was performed in 38,455 (96%) of all patients. Wrist access adoption in the majority of cardiovascular interventions is possible in all PCI centres in Europe if an appropriate national strategy is developed.

Newly Diagnosed Diabetes and Stress Glycaemia and Its' Association with Acute Coronary Syndrome.

BACKGROUND: Diabetes is diagnosed in 10-20% of patients with acute coronary syndrome (ACS) not known to be diabetics. Elevated blood glucose is an independent risk factor for cardiac events, regardless of presence of diabetes. AIM: Evaluating the prevalence of new-diagnosed DM among patients with ACS, and assessing the relationship between stress glycaemia and new diagnosed DM with in-hospital cardiac events. METHODS: Prospective observational study, in patients with ACS, in whom we analyzed parameters of glycemic metabolism, clinical data, and in-hospital cardiac events. We comparatively analyzed patients according to the HgbA1C and known DM in five groups: non-DM (< 5.6%), new pre-DM (5.6-6.5%), new DM (≥ 6.5%), controlled (<7%) and uncontrolled (≥7%) known DM. RESULTS: 150 patients, (93 male and 57 female) were included. Impaired glucose metabolism was detected in 44.5% of patients, 7.9% of whom were newly-diagnosed DM. The highest levels of stress glycaemia were found in new and uncontrolled known DM. The in-hospital event rate was 20.7%, the mortality rate 7.3%, being the highest in new diagnosed and uncontrolled known DM patients. CONCLUSIONS: The prevalence of unknown DM was high among patients with ACS. Stress glycaemia and failure to achieve glycemic controlee, were an independent predictors of in-hospital cardiac events.
