Comparison of MANTA vs ProGlide Vascular Closure Device and 30-Day Outcomes in Transfemoral Transcatheter Aortic Valve Implantation.

BACKGROUND: Vascular complications (VCs) after transfemoral transcatheter aortic valve implantation (TAVI) have an increased mortality risk, and vascular closure device (VCD) use is mandatory. The percutaneous MANTA VCD (Teleflex) is a novel collagen-based technology for closure of large-bore arteriotomies. We compared the MANTA VCD with the suture-based ProGlide VCD (Abbott Vascular). METHODS: A retrospective review was performed on all consecutive patients who underwent transfemoral TAVI in our center from January 1, 2015, to February 28, 2021, and 30-day outcomes were recorded. Major adverse cardiovascular events (MACE) were cardiac death, disabling stroke, and/or major VCs. Access site-related VCs were VCs related to the access site vessel from which the transcatheter valve was introduced and advanced. RESULTS: The MANTA VCD was used in 99 patients and the ProGlide in 224. There was 4.0% MACE in the MANTA group and 4.9% in the ProGlide group (P = .999). Overall VCs were 10.1% vs 7.6%, major VCs were 3.0% vs 2.2%, and minor VCs 7.1% vs 5.4%(P = .753). Access site-related VCs were 5.1% vs 5.8% in the (P = .999), and periprocedural vascular surgical intervention was needed in 6.1% of the MANTA group vs 2.2% of the ProGlide group (P = .099). CONCLUSION: There was no significant difference in MACE, mortality, cardiovascular mortality, VCs, access site-related VCs, periprocedural vascular surgical interventions, bleeding, or transfusion rate between the 2 groups. The MANTA VCD group had more periprocedural vascular surgical interventions which did not reach statistical significance.

Outcomes of transfemoral transcatheter aortic valve implantation (TAVI) and predictors of thirty-day major adverse cardiovascular events (MACE) and one-year mortality.

OBJECTIVE: TAVI is more frequently used to treat aortic stenosis with the mandate to have a low as possible rate of adverse events. We present our 30-day outcomes and one-year mortality and examine the factors associated with them. METHODS: A prospective evaluation was performed of all patients who underwent transfemoral TAVI in Nicosia General Hospital from January 2015 until March 2020. MACE were defined as cardiac death, disabling stroke, and/or major vascular complications (VC). Multiple logistic and Cox regression analyses were used to identify the factors associated with 30-day MACE and one-year mortality, respectively. RESULTS: A total of 235 TAVI procedures were performed (178 balloon-expandable, 57 self-expandable). Thirty-day outcomes were MACE: 4.3%, cardiovascular death: 2.1%, disabling stroke: 1.3%, major VC: 1.7%, and contrast induced nephropathy (CIN): 4.3%. There was a rate of 6.2% new pacemaker implantations and 0.9% of more than mild aortic valve regurgitation (AR) at 30 days. Mortality at one year was 15.1%. The balloon-expandable valves appear to have less new pacemakers, less mild AR, lower contrast volume used, and less days of hospitalization, while the self-expandable valves have lower post-procedural gradients. Low hemoglobulin, history of atrial fibrillation (AF), and lower BMI were predictors of 30-day MACE. Serum creatinine >2 mg/dL, history of AF, RVSP >60 mmHg and major VC are predictors of one-year mortality. CONCLUSION: We have shown excellent 30-day results with low incidence of adverse events for both the balloon-expandable and self-expandable valves. Clinical factors are the main predictors of both 30-day MACE and one-year mortality; major VC is a strong predictor of one-year mortality.

A case of crossing coronary arteries.

We present the case of a patient in whom coronary angiography, performed due to severe calcific aortic stenosis, revealed crossing between the left anterior descending artery and the first diagonal branch. There is only a single report presenting this particular coronary anatomy, whereas this is the eleventh case of crossing coronary arteries ever reported. The clinical implications of this variant coronary anatomy with regard to diagnostic angiography and selection of revascularization procedures are briefly discussed.
