BACKGROUND: In 5%-25% of non-ST-elevation acute coronary syndrome (NSTE-ACS) patients, coronary angiography reveals no obstructive coronary arteries (MINOCA). Coronary microvascular disease (CMD) is a potential causal pathophysiological mechanism in these patients and can be diagnosed by continuous thermodilution assessment. Recently, the microvascular resistance reserve (MRR) has been introduced as a novel index to assess the vasodilatory capacity of the microcirculation. However, continuous thermodilution and MRR have never been investigated in the acute setting in MINOCA patients and invasive assessment of the microcirculation in these patients are currently lacking...

Nowadays, the long-life management of patients with aortic stenosis has emerged as one of the most debated issues. Transcatheter aortic valve replacement is more frequently performed in younger patients with lower surgical risk, and also the number of valve-in-valve (ViV) procedures has increased in the last few years. However, coronary obstruction is the most dreadful complication related to this procedure. To prevent coronary obstruction in the context of transcatheter aortic ViV implantation, the BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) technique was developed...

In the absence of standardized management guidelines, coronary artery aneurysms (CAAs) present therapeutic challenges. Percutaneous coronary intervention (PCI) is rarely explored, especially in giant aneurysms with persistent angina, where surgery might be presumed as a preferred option. We describe the technical aspects and feasibility of PCI using Gore Viabahn expanded polytetrafluoroethylene (ePTFE)-covered nitinol self-expanding stents in a 66-year-old woman with a complex medical history and an enlarging, symptomatic right coronary artery aneurysm...

BACKGROUND: Challenging anatomies and comorbidities have impact on success in transcatheter aortic valve replacement (TAVR). There is controversy whether the extent of the aortic angle (AA) has an impact on procedural outcomes. Matched comparative outcome data of new generation transcatheter heart valves (THVs) in horizontal aorta (HA) are scarce. METHODS: A total of 1582 patients with severe native aortic stenosis (AS) treated with the SAPIEN3 Ultra (Ultra; n = 526) or ACURATE Neo2 (Neo2; n = 1056) THVs from January 2017 to January 2023 were analyzed...

Despite advancements in technology, operator experience, and procedural planning, transcatheter aortic valve replacement (TAVR) procedures are complex, and complications remain inevitable. Valve embolization may prove to be fatal and conventional rescue techniques are dependent on the anatomy of the aorta. We describe a case of postimplant embolization of a self-expanding valve during valve-in-valve application where the valve could not be stabilized due to the anatomy of the aorta and a novel technique was utilized to stabilize the valve in the aortic arch using a wire fixed to the left axillary artery...

Randomized clinical trials failed to show additional benefit of renal artery stenting on top of medical therapy. Instead of writing an obituary on renal artery stenting, we try to explain these disappointing results. A transstenotic pressure gradient is needed to reduce renal perfusion and to activate the renin-angiotensin-aldosterone system. In only a minority of patients included in trials, a transstenotic pressure gradient is measured and reported. Like the coronary circulation, integration of physiological lesion assessment will allow to avoid stenting of non-significant lesions and select those patients that are most likely to benefit from renal artery stenting...

BACKGROUND: Vasopressor test (VPT) might be useful in patients with functional mitral regurgitation (MR) and left ventricular dysfunction (MITRA-FR-like patients) during transcatheter edge-to-edge repair (TEER). AIMS: We aimed to evaluate the prognostic impact of VPT. METHODS: MR treated with TEER were included in a multicenter prospective registry. VPT was used intraprocedurally in patients with left ventricular dysfunction and/or hypotension...

BACKGROUND: Hybrid stage I palliation (HS1P) is an alternative approach for initial palliation in hypoplastic left heart syndrome (HLHS) patients. Unlike surgical stage I palliation where atrial septectomy is routinely performed, atrial septal intervention (ASI) during HS1P is variable. In this study, we described our experience with ASI in single ventricle (SV) patients who underwent HS1P and identified factors associated with need for ASI after HS1P. METHODS: Data were retrospectively collected for all HLHS patients who underwent HS1P at our center over the past 12 years...

BACKGROUND: Most patients undergoing the mitral transcatheter edge-to-edge repair (TEER) technique are elderly comorbid patients. Low body mass index (BMI) < 23 kg/m2 has been identified in other elderly populations as a risk factor, but has not been studied sufficiently in mitral TEER. AIMS: We aimed to study the impact of low BMI (23 kg/m2) on the outcome after mitral TEER. METHODS: Patients undergoing first-time TEER for mitral regurgitation at a single tertiary center were included, with the exclusion of patients with preprocedural hemodynamic instability or missing BMI...

REVIEW

Frailty is a common clinical syndrome that portends poor peri-procedural outcomes and increased mortality following transcatheter valve interventions. We reviewed frailty assessment tools in transcatheter intervention cohorts to recommend a pathway for preprocedural frailty assessment in patients referred for transcatheter valve procedures, and evaluated current evidence for frailty interventions and their efficacy in transcatheter intervention. We recommend the use of a frailty screening instrument to identify patients as frail, with subsequent referral for comprehensive geriatric assessment in these patients, to assist in selecting appropriate patients and then optimizing them for transcatheter valve interventions...

BACKGROUND: The anatomic substrate of bicuspid valves may lead to suboptimal TAVR stent expansion and geometry. AIM: We evaluated determinants of stent geometry in bicuspid valves treated with Sapien transcatheter aortic valve replacement (TAVR) valves. METHODS: A multicenter retrospective registry of patients (February 2019 to August 2022) who underwent post-TAVR computed tomography to determine stent area (vs. nominal valve area) and stent ellipticity (maximum diameter/minimum diameter)...
