    Acute stroke intervention for acute embolic procedural strokes performed by cardiologists
    Wiley ; 2021

    Abstract: Acute ischemic stroke is a feared complication during cardiovascular procedures associated with high morbidity and mortality if not immediately recognized and treated. We conducted a review of cases at our center where patients experienced an acute, procedure‐related ischemic stroke and underwent immediate endovascular stroke treatment by the interventional cardiologists trained in acute endovascular stroke intervention. Baseline demographics, procedural and follow‐up data were collected. Three patients were identified in whom the percutaneous procedure (peripheral arterial intervention, transapical NeoChord [NeoChord Inc, Minnesota, USA] implantation and transcatheter aortic valve implantation, respectively) was complicated by an acute embolic ischemic stroke. In all cases, cerebral vessel re‐canalization was technically successful with thrombolysis in cerebral infarction (TICI) IIB/III flow. Follow‐up computed tomography scans showed no infarct demarcation, oedema or intracranial hemorrhage. One patient survived with no neurological symptoms at 6‐month follow‐up whereas the two other patients died of unrelated intensive care complications and decompensated heart failure. We conclude that endovascular stroke treatment during cardiovascular interventions can be performed by interventional cardiologists with appropriate training. It offers the unique opportunity to treat cerebral embolization in a time‐efficient manner, potentially improving morbidity and mortality of affected patients.

    Abstract: To describe the feasibility and safety of transcatheter aortic valve implantation (TAVI) with a visiting on‐site cardiac surgery program for surgical back‐up . Background Both European and American guidelines recommend institutional cardiac surgery back‐up for TAVI. However, the conversion to cardiac surgery is very rare, many complications of TAVI can be managed by catheter techniques and a visiting team can also provide surgical stand‐by. Therefore, the need for institutional cardiac surgery (by a surgeon who routinely performs conventional surgical valve replacement at the institution performing TAVI) has been questioned . Methods A retrospective review of consecutive TAVI cases with visiting on‐site cardiac surgery was performed. Key demographic, echocardiographic, and procedural data were collected prospectively . Results A total of 97 patients (81.9 ± 6.3 years) with high‐risk criteria (log Euroscore 21.6 ± 14.4, chronic renal failure 39.2%, severe systolic dysfunction 24.7%) underwent TAVI with visiting on‐site cardiac surgery at our institution. Local anesthesia with or without conscious sedation was used in 94.8% of patients. Procedural technical success was 100%, with 2 episodes of tamponade (both treated with pericardiocentesis) and a 16.5% vascular complication rate (all treated conservatively or percutaneously). Thirty‐day mortality was 3.1%, with 5.2% rate of stroke and 8.2% rate of major bleeding. There were no conversions to surgery . Conclusions TAVI can be done safely in the setting of a hospital with visiting on‐site cardiac surgery. This requires careful patient selection, experienced operators and surgeons in experienced centers with well‐established criteria and processes of care. In this setting, it may be an option for hospitals without institutional cardiac surgery . (J Interven Cardiol 2015;28:76–81)

    Optimal protamine‐to‐heparin dosing ratio for the prevention of bleeding complications in patients undergoing TAVR—A multicenter experience
    Wiley ; 2023

    Abstract: Despite major advances, transcatheter aortic valve replacement (TAVR) is still associated with procedure‐specific complications. Although previous studies reported lower bleeding rates in patients receiving protamine for heparin reversal, the optimal protamine‐to‐heparin dosing ratio is unknown. Hypothesis The aim of this study was a comparison of two different heparin antagonization regimens for the prevention of bleeding complications after TAVR. Methods The study included 1446 patients undergoing TAVR, of whom 623 received partial and 823 full heparin antagonization. The primary endpoint was a composite of 30‐day mortality, life‐threatening, and major bleeding. Safety endpoints included stroke and myocardial infarction at 30 days. Results Full antagonization of heparin resulted in lower rates of the primary endpoint as compared to partial heparin reversal (5.6% vs. 10.4%, p   〈  .01), which was mainly driven by lower rates of life‐threatening (0.5% vs. 1.6%, p  = .05) and major bleeding (3.2% vs. 7.5%, p   〈  .01). Moreover, the incidence of major vascular complications was significantly lower in patients with full heparin reversal (3.5% vs. 7.5%, p   〈  .01). The need for red‐blood‐cell transfusion was lower in patients receiving full as compared to partial heparin antagonization (10.4% vs. 15.9%, p   〈  .01). No differences were observed in the incidence of stroke and myocardial infarction between patients with full and partial heparin reversal (2.2% vs. 2.6%, p  = .73 and 0.2% vs. 0.4%, p  = .64, respectively). Conclusions Full heparin antagonization resulted in significantly lower rates of life‐threatening and major bleeding after TAVR as compared to partial heparin reversal. The occurrence of stroke and myocardial infarction was low and comparable between both groups.

    Abstract: Transcatheter aortic valve replacement (TAVR) is a leading‐edge therapy option for patients with severe aortic stenosis (AS) and high surgical risk. However, this minimally invasive procedure is associated with specific complications that may be life‐threatening. Valvuloplasty balloon entrapment during postdilatation in transcatheter self‐expanding aortic valve stent frames has not yet been a focus of interest in this context. Although it is a rare event, it may critically influence outcome, and different management strategies can be considered. Hereafter, we present the case of a 67‐year‐old male who underwent transfemoral TAVR and subsequent postdilatation. The valvuloplasty balloon was entrapped in the self‐expanding aortic valve stent frame after inadvertent wire passage through the outflow struts. Since surgical risk was high, we preferred a percutaneous approach and extracted the entrapped balloon with high traction force under rapid pacing after valve stabilization with another balloon, which was placed in the annular position.

    Abstract: The impact of a horizontal aorta (HA) on adverse events (AE) following in transcatheter aortic valve replacement (TAVR) is dealt controversially. Using new‐generation self‐expandable devices, we aimed to reevaluate an appropriate threshold of the aortic root angulation (ARA) in terms of HA and its impact on outcome. Methods The 466 consecutive patients, who underwent transfemoral TAVR with self‐expandable new‐generation devices, were analyzed. Patients were classified into cases with HA (ARA ≥ 51°; n = 225; 48%) and without HA (ARA  〈 51°; n = 241; 52%). Primary endpoints were device success and 30‐day mortality. Secondary endpoints were specific AE according to VARC‐2 definitions. Results Contrast use (107.6 ± 50.1 vs. 94.1 ± 46.1 ml; p = .033) and radiation dose (3,176 [1,928–5,596] vs. 2,651 [1,643–4,394] Gyxcm 2 ; p = .016) were higher in HA. Primary device success was comparable (97.1 vs. 97.8%; p = .773). A 30‐day mortality (3.3 vs. 0.4%; p = .038, plogrank = 0.025), stroke (7.1 vs. 2.7%; p = .033), and major vascular complications (MVASC) (6.6 vs. 2.7%; p = .050) were more frequent in HA. Pronounced calcification of the noncoronary cusp and left ventricular outflow tract, the condition of HA, as well as repositioning maneuvers were independent predictors for overall specific AE. Conclusion An HA above 51° is associated with an increased rate of stroke, MVASC, and 30‐day mortality. Valve size and asymmetric calcification affect the incidence of repositioning maneuvers and subsequent VARC‐2 AE, indicating that an HA—together with specific anatomic features—remains a crucial factor for TAVR‐related outcome with self‐expandable new‐generation devices.

    Abstract: To evaluate outcome assessment of percutaneous balloon aortic valvuloplasty (BAV) in different flow and gradient patterns of severe aortic stenosis (AS). Background The mean pressure gradient reduction after BAV is an often‐used surrogate parameter to evaluate procedural success. The definition of a successful BAV has not been evaluated in different subgroups of severe AS, which were introduced in the latest guidelines on the management of patients with valvular heart disease. Methods In this observational study, consecutive patients from July 2009 to March 2018 undergoing BAV were divided into normal‐flow high‐gradient (NFHG), low‐flow low‐gradient (LFLG), and paradoxical low‐flow low‐gradient (pLFLG) AS. Baseline characteristics, hemodynamic, and clinical information were collected and compared. Results One‐hundred‐fifty‐six patients were grouped into NFHG (n = 68, 43.5%), LFLG (n = 68, 43.5%), and pLFLG (n = 20, 12.8%) AS. Mean age of the study population was 81 years. Cardiogenic shock or refractory heart failure (46.8%) was the most common underlying reasons for BAV. Spearman correlation revealed that the mean pressure gradient reduction, determined by echocardiography, had a moderate correlation with the increase in the aortic valve area (AVA) in patients with NFHG AS (ρ: 0.529, p 〈  .001) but showed no association in patients with LFLG (ρ: 0.017, p = .289) and pLFLG (ρ: 0.030, p = .889) AS. BAV as bridge to surgical or transcatheter aortic valve replacement was possible in 44.2% of patients, with no difference between groups ( p = .070). Conclusion The mean pressure gradient reduction might be an adequate surrogate parameter for BAV success in patients with NFHG AS but is not suitable for patients with other hemodynamic entities.

    Abstract: Paravalvular leak (PVL) after percutaneous transcatheter aortic valve replacement (TAVR) is associated with significant morbidity and mortality. Percutaneous PVL closure has been reported for balloon‐expandable valves but not self‐expandable valves. Methods We conducted a review of cases at our center where patients who received TAVR with self‐expandable valves and went on to develop severe PVL underwent percutaneous closure. Baseline demographic, TAVR procedural, PVL procedural, and follow‐up data were collected. Results A total of five patients with severe PVL after TAVR with a self‐expanding valve underwent percutaneous PVL closure. Four of five patients had a trial of balloon postdilatation after valve deployment and had significant persistent PVL. In all five patients, PVL went from moderate‐severe to mild‐moderate PVL. There were no adverse events. Conclusion Percutaneous PVL closure for severe PVL self‐expanding valve for TAVR is a safe and efficacious procedure. Procedural technique involves transesophageal guidance, a high approach through the valve struts, deployment of an appropriate size device, and careful monitoring. This method may be part of the algorithm for severe PVL after TAVR. © 2013 Wiley Periodicals, Inc.

    Abstract: This meta‐analysis sought to assess predictors of permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR) with focus on preprocedural multi‐slice computed tomography (MSCT) derived data. Background Transcatheter aortic valve replacement (TAVR) has expanded to a well‐established treatment for severe symptomatic aortic stenosis at high and intermediate surgical risk. PPI after TAVR remains one of the most frequent procedure‐related complications and appears to be influenced by several factors. Methods The authors conducted a literature search in PubMed/MEDLINE and EMBASE databases to identify studies that investigated preprocedural MSCT data and the rate of PPI following TAVR with new‐generation devices. Results Ten observational studies ( n  = 2707) met inclusion criteria for the final analysis. PPI was performed in 387 patients (14.3%) after TAVR. Patients requiring PPI had a larger annulus perimeter (MD: 1.66 mm; p  〈  .001) and a shorter membranous septum length (MD: −1.1 mm; p  〈  .05). Concerning calcification distribution, patients with requirement for new pacemaker implantation showed increased calcification of the left coronary cusp (MD: 47.6 mm 3 ; p  〈  .001), and the total left ventricular outflow tract (MD: 24.42 mm 3 ; p  〈  .01). Lower implantation depth (MD: 0.95 mm; p  〈  .05) and oversizing (MD: 1.52%; p  〈  .05) were procedural predictors of PPI following TAVR. Conclusions Besides the well‐known impact of electrocardiographic and procedure‐related factors on conduction disturbances, MSCT derived distribution of the aortic valve and left ventricular outflow tract calcification, as well as membranous septum length, are associated with an increased risk of PPI following TAVR.
