Reducing Patient Radiation Dose With Image Noise Reduction Technology in Transcatheter Aortic Valve Procedures
2015
X-ray radiation exposure is of great concern for patients undergoing structural heart interventions. In addition, a larger group of medical staff is required and exposed to radiation compared with percutaneous coronary interventions. This study aimed at quantifying radiation dose reduction with implementation of specific image noise reduction technology (NRT) in transcatheter aortic valve implantation (TAVI) procedures. We retrospectively analyzed 104 consecutive patients with TAVI procedures, 52 patients before and 52 after optimization of x-ray radiation chain, and implementation of NRT. Patients with 1-step TAVI and complex coronary intervention, or complex TAVI procedures, were excluded…
External rotation strength deficit after hip resurfacing surgery.
2008
The aim was to assess the effect of resurfacing hip arthroplasty on hip muscle function, when, in the posterior approach, the piriformis tendon and outer rotators of the hip joint were divided. The unoperated side was used as a control.Thirty-three consecutive patients (mean age 55 years, 73% males) were operated using the posterior approach. Main outcome measures were isometric muscle strength of external and internal rotators and extensors of the hip and hip pain.Hip external rotation strength (p0.001) and leg extension strength (p0.001) were significantly lower on the operated side compared with the un-operated side prior to the surgery. On the operated side external rotation strength de…
Terminal or truncal ligation of the inferior thyroid artery during thyroidectomy? A prospective randomized trial.
2016
Abstract Introduction Thyroidectomy is a common procedure in general and endocrine surgery. The technique of ligation of inferior thyroid artery (ITA) has been invoked as a possible cause of appearance of postoperative hypocalcemia. Methods We performed a prospective randomized study involving 184 patients undergoing total thyroidectomy to evaluate the differences of truncal ligation versus distal ligation of ITA in terms of postoperative hypocalcemia, vocal fold palsy, voice and swallowing impairment. The patients were divided into group A (trunk ligation of ITA) and group B (terminal branches ligation of ITA). Results We evaluated postoperative PTH and calcemia (immediate, 6 and 12 months…
Usefulness of Clopidogrel Loading in Patients Who Underwent Transcatheter Aortic Valve Implantation (from the BRAVO-3 Randomized Trial)
2018
P2Y12-inhibitor initiation with clopidogrel using a loading dose (LD) versus no LD (NLD) provides more rapid inhibition of platelet activation and reduced risk of ischemic events after coronary stenting. Whether a similar beneficial effect is achieved in the setting of transcatheter aortic valve implantation (TAVI) is unknown. We evaluate the effects of preprocedural clopidogrel LD versus no NLD on 48-hour and 30-day clinical outcomes after TAVI. In the BRAVO-3 trial, 802 patients with severe aortic stenosis who underwent transfemoral TAVI were randomized to intraprocedural anticoagulation with bivalirudin or unfractionated heparin. Administration of clopidogrel LD was left to the discretio…
Immunoglobulin G4-Related Aortitis and Severe Aortic Valve Stenosis Treated With Transcatheter Aortic Valve Replacement and Immunosuppression.
2021
Abstract IgG4-related disease is an immune-mediated fibro-inflammatory disorder with multisystemic involvement. Aortitis and peri-aortitis are the most common cardiovascular manifestations of the disease. We present the case of a 65-year-old man with symptomatic severe aortic stenosis and concomitant IgG4 aortitis. The diagnosis was confirmed by IgG4 serum levels, positive positron emission computed tomography (PET-CT) scans, and pathology from mediastinal dissection. Surgical aortic valve replacement (SAVR) was unfeasible owing to extensive mediastinal fibrosis, and transcatheter aortic valve replacement (TAVR) was successfully performed. As ascending aorta access for SAVR in IgG4 aortitis…
Differential Prognostic Value of Galectin-3 According to Carbohydrate Antigen 125 Levels in Transcatheter Aortic Valve Implantation
2019
Galectin-3 (Gal-3) and carbohydrate antigen 125 (CA125) have been associated with adverse outcomes after transcatheter aortic valve implantation (TAVI). Experimental data have suggested a potential molecular interaction. Therefore, we assessed the association of Gal-3 and CA125 with prognosis after TAVI.A total of 439 patients were enrolled. The primary endpoint was a composite of all-cause mortality or readmission for worsening heart failure after TAVI.The primary endpoint occurred in 16.4%. Gal-3 was dichotomized at ≥ 8.71 ng/mL into elevated and not elevated. Gal-3 was elevated in 31.9% and was associated with a higher risk of the primary endpoint (25% vs 12.4%, HR, 2.26; P.001). After m…
Comparison of Carbohydrate Antigen 125 and N-Terminal Pro-Brain Natriuretic Peptide for Risk Prediction After Transcatheter Aortic Valve Implantation
2017
Elevated carbohydrate antigen 125 (CA125) and N-terminal pro-brain natriuretic peptide (NTproBNP) have been associated with adverse outcome after transcatheter aortic valve implantation (TAVI). This study performs a comparison of both biomarkers for prognosis after TAVI. The study includes 363 patients. The primary end point was all-cause death or readmission for worsening congestive heart failure within 1 year after TAVI, and this end point occurred in 16% of the population. The optimal cutoff to predict the primary end point was 18.4 U/ml for CA125 and 2,570 ng/L for NTproBNP. Elevated CA125 levels were present in 52% and were associated with a higher rate of the primary end point (27% vs…
Validity and reliability of isometric, isokinetic and isoinertial modalities for the assessment of quadriceps muscle strength in patients with total …
2013
Reliability of isometric, isokinetic and isoinertial modalities for quadriceps strength evaluation, and the relation between quadriceps strength and physical function was investigated in 29 total knee arthroplasty (TKA) patients, with an average age of 63 years. Isometric maximal voluntary contraction torque, isokinetic peak torque, and isoinertial one-repetition maximum load of the involved and uninvolved quadriceps were evaluated as well as objective (walking parameters) and subjective physical function (WOMAC). Reliability was good and comparable for the isometric, isokinetic, and isoinertial strength outcomes on both sides (intraclass correlation coefficient range: 0.947-0.966; standard…
Maximal voluntary isokinetic knee flexion torque is associated with femoral shaft bone strength indices in knee replacement patients.
2012
It is currently unknown whether knee replacement-associated bone loss is modified by rehabilitation programs. Thus, a sample of 45 (18 men and 25 women) persons with unilateral knee replacement were recruited; age 66 years (sd 6), height 169 cm (sd 8), body mass 83 kg (sd 15), time since operation 10 months (sd 4) to explore the associations between maximal torque/power in knee extension/flexion and femoral mid-shaft bone traits (Cortical cross-sectional area (CoA, mm(2)), cortical volumetric bone mineral density (CoD, mg/mm(3)) and bone bending strength index (SSI, mm(3))). Bone traits were calculated from a single computed tomography slice from the femoral mid-shaft. Pain in the operated …
