Access-site complications of transradial percutaneous coronary intervention using sheathless guiding catheters for acute coronary syndrome: a prospective cohort study with radial ultrasound follow-up

AbstractThe advantages of sheathless guiding catheters over the conventional approach using sheaths in percutaneous coronary intervention (PCI) regarding access-site complications, particularly ultrasound-diagnosed radial artery occlusion (RAO), remain unknown. The present study investigated the incidence of access-site complications of transradial primary PCI using sheathless guiding catheters in acute coronary syndrome (ACS). This prospective study evaluated access-site complications in 500 patients with ACS undergoing sheathless transradial primary PCI. Doppler ultrasound evaluation of the radial arteries was performed 2 and 30  days after the procedure. Sheathless guiding catheters (7.5-Fr) were used in 91.0% of the patients. The procedural success rate was 98.4%. Ultrasound-diagnosed RAO rates were 2.0% and 3.8% at 2- and 30-day follow-ups, respectively. Logistic regression analysis identified that the sheath-to-artery ratio (per 0.1) (odds ratio [OR] 5.71; 95% confidence interval [CI] 1.18–27.71;p = 0.001) was associated with more frequent RAO and that hypertension (OR 0.22; 95% CI 0.06–0.81;p = 0.023) was associated with less frequent RAO. Receiver operating characteristic curve analysis revealed that a sheath-to-artery ratio of 1.47 was the cutoff for 30-day post-procedural RAO (sensitivity 72%, specificity 81%). Sheathless transradial primary PCI for ACS was associated with a low incidence of access-site complications and ...

Suprarenal abdominal aortic coarctation (SAAC) is a congenital midaortic syndrome that develops owing to a developmental anomaly in the fusion of the embryonic dorsal aortae. This condition is associated with severe hypertension, which is usually the indication for intervention. Open surgery is the primary treatment and it typically involves thoracoaortic bypass (TAB), and less commonly patch aortoplasty (PA). Bypass to the visceral vessels has also been performed in conjunction with TAB or PA. The majority undergoing intervention for SAAC are children and adolescents; therefore, the benefits of surgical intervention must ...

Authors: BaHammam AS, Almeneessier AS Abstract Previous studies have assessed the role of gender and menopause in Obstructive Sleep Apnea (OSA). It is well known that menopause is a major risk factor for OSA. However, analogous studies on obesity Hypoventilation Syndrome (OHS) are limited. Recent studies have suggested that OHS is more prevalent in postmenopausal women. Moreover, women with OHS seem to have excess comorbidities, including hypothyroidism, hypertension, pulmonary hypertension, and diabetes mellitus, compared to men. In the present perspective, we discuss recent data on the prevalence and comorbiditie...

We report the case of a 72-year-old woman with limited systemic sclerosis, who was initially diagnosed with systemic sclerosis-related pulmonary arterial hypertension. However, after introduction of sildenafil and bosentan, the patient developed acute pulmonary oedema, and findings from complementary exams were suggestive of PVOD.
