OBJECTIVES: To evaluate the association between measurements performed during Medtronic CoreValve (MCV) deployment and paravalvular leak (PVL). BACKGROUND: The MCV can be recaptured and repositioned, allowing the TAVR operator to implant at a more favorable position. The association between angiographic measurements of MCV position while the valve is recapturable and PVL post deployment has not been investigated. METHODS: 493 patients undergoing TAVR with MCV (January 2011-July 2017) were included...

INTRODUCTION: Leaflet thrombosis (LT) defined by computed tomography (CT) following transcatheter aortic valve replacement (TAVR) has been shown to increase cerebrovascular events. The neo-sinus plays an important role in the development of LT. Intra-annular valves (IAV) have a larger neo-sinus when compared to supra-annular valves (SAV), and has been associated with larger thrombus burden. The prevalence of LT with IAV and SAV in a larger, diverse cohort is unknown. METHODS: We performed a systematic review to assess the prevalence of LT in IAV versus SAV TAVR prostheses...

Acute vessel closure due to dissection is a known complication of percutaneous coronary intervention and can be challenging to treat, especially if guidewire position is lost. Re-entering into the distal true lumen is commonly done during chronic total occlusion interventions, as part of antegrade dissection strategies. We report two cases of acute vessel closure and guidewire position loss in which the Stingray LP system was successfully used to advance a guidewire into the distal true lumen and recanalize the occluded vessel...

OBJECTIVES: The aim of this study was to assess the predictive value of PMA measurement for mortality. BACKGROUND: Current surgical risk stratification have limited predictive value in the transcatheter aortic valve implantation (TAVI) population. In TAVI workup, a CT scan is routinely performed but body composition is not analyzed. Psoas muscle area (PMA) reflects a patient's global muscle mass and accordingly PMA might serve as a quantifiable frailty measure. METHODS: Multi-slice computed tomography scans (between 2010 and 2016) of 583 consecutive TAVI patients were reviewed...

A 78-year-old man was admitted to the emergency department because of chest pain following blunt chest trauma. Chest X-ray revealed multiple rib fractures. However, electrocardiogram showed ST elevation in inferior leads suggesting acute myocardial infarction (AMI). Emergency coronary angiography revealed normal left coronary artery and occluded proximal right coronary artery. Thus, percutaneous coronary intervention (PCI) was performed immediately. Antegrade PCI was unsuccessful due to a very large false lumen, which was caused by a blunt trauma...

OBJECTIVES: The aim was to assess the extent of coronary artery disease and revascularization using baseline SYNTAX Score (bSS) and residual SYNTAX Score (rSS) in patients with cardiogenic shock (CS) secondary to ST-segment elevation myocardial infarction (STEMI). The prognostic impact of SYNTAX Score (SS) was evaluated and assessed for additive value over clinical risk scores. BACKGROUND: bSS and rSS have been proven to be useful in risk stratification in stable coronary artery disease as well as in acute coronary syndromes, but they have not been studied in STEMI related CS...

Blunt chest trauma is a common occurrence in vehicle accident. Cardiac injuries following nonpenetrating thoracic trauma have been reported. ST-elevation myocardial infarction (STEMI) due to coronary artery involvement is a rare but extremely serious condition for the high risk of undetected diagnosis. Blunt thoracic trauma may obscure typical chest pain associated with cardiac ischemia especially in patients with high tolerance of pain or secondary administration of analgesic drugs. We report two consecutive cases of young adults admitted to our emergency department after motorcycle accident and concomitant anterior STEMI due to occlusion of left anterior descending artery...

OBJECTIVE: We sought to evaluate the feasibility, technical aspects, and outcome of transcatheter perimembranous ventricular septal defect (pmVSD) closure using duct occluder devices with a single retention disc. BACKGROUND: Use of duct occluder devices to close pmVSD seems a promising alternative therapy. However, limited data exist on this technique. METHODS: From 2010 to 2016, 222 patients (female 47.7%) were identified from databases of five participating institutions in whom pmVSD closure was attempted using an Amplatzer Duct Occluder I or Lifetech duct occluder device...

Percutaneous edge-to-edge repair of severe mitral regurgitation has been established as an alternative treatment option for patients at high risk for cardiac surgery. More recently, the introduction of the Cardioband system enabled percutaneous direct annuloplasty. Here, we present a case of simultaneous percutaneous direct annuloplasty with edge-to-edge repair. Moreover, annuloplasty did facilitate clip implantation bei approximating the anterior and posterior mitral leaflet. In conclusion, the combination of direct annuloplasty with edge-to-edge repair is feasible in a single procedure...

OBJECTIVE: We investigated radioprotective strategies for the interventional echocardiographer (IE) during structural heart interventions in comparison with the interventional cardiologist (IC). BACKGROUND: Structural heart interventions are expanding in complexity with increased reliance on IE. Recent reports have demonstrated concerning exposure and higher radiation to the IE. METHODS: We monitored 32 structural interventions - 19 transcatheter aortic valve replacements (TAVR), 6 transcatheter mitral valve repairs, 5 paravalvular leak closures, and 2 atrial septal defect closures...

Transfemoral approach is considered the preferred route to perform transcatheter aortic valve implantation (TAVI) by most operators due to the low invasiveness and good outcome, as compared to non-transfemoral approach. However, transfemoral access is not always feasible particularly in patients with small and calcific vessels. Recently, catheter-based lithoplasty has emerged as a new technique based on the use of circumferential pulse pressure waves to disrupt calcific plaques. This technology may help to expand eligibility for transfemoral TAVI to patients with calcific ileo-femoral vessels and at high risk for non-transfemoral approach...

BACKGROUND: Optimal implantation results of bioresorbable scaffolds (BRS) are typically assumed to require postdilatation with non-compliant (NC) balloons to achieve full scaffold apposition and minimize event rates. We systematically evaluated the mechanical effect of NC balloon postdilatation on magnesium-based BRS (Magmaris®, Biotronik AG, Bülach, Switzerland) in vivo. METHODS: In 35 patients, 40 Magmaris® BRS were implanted to treat 37 de novo coronary artery stenoses...

AIM: Use of a BRS either in clinical practice or in the setting of an acute myocardial infarction (MI) is controversial. Despite an overall high rate of thrombosis, vascular healing response following BRS implantation tend to superiority as compared to metallic drug-eluting stent in ST-segment elevation myocardial infarction (STEMI) patients. We sought to compare the in-stent/scaffold vasomotion between metallic bioresorbable scaffold (BRS) and sirolimus eluting stent (SES) at 12-month angiographic follow-up in the setting of patients with STEMI treated by primary PCI...

Valve-in-valve (ViV) procedures for failing bioprostheses carry a certain risk for device malfunction. We herein report a case of a failing Evolut R in a deteriorated Mitroflow, treated with a Sapien 3. An 81 year old female patient received surgical aortic valve replacement and was treated by ViV due to deterioration. Three years later, echocardiography revealed a pressure gradient of peak/mean 105/63 mmHg. Subsequently, a second ViV procedure with initial intentional rupture of the bioprosthetic stent was performed...
