Adding Surgical Edge-to-Edge Mitral Valve Repair to Myectomy in Hypertrophic Obstructive Cardiomyopathy: Long-Term Functional and Echocardiographic Outcome.

This study evaluates the early and long-term clinical and echocardiographic outcome of edge-to-edge (E2E) mitral valve repair (MVr) concomitant to septal myectomy (SM) in patients with symptomatic hypertrophic obstructive cardiomyopathy (HOCM). A retrospective single-center analysis was performed of patients who underwent isolated SM or SM with E2E MVr from 2011 to 2022. Exclusion criteria were primary mitral valve (MV) disease or concomitant valve surgery.

OCT or Angiography Guidance for PCI in Complex Bifurcation Lesions.

Background: Imaging-guided percutaneous coronary intervention (PCI) is associated with better clinical outcomes than angiography-guided PCI. Whether routine optical coherence tomography (OCT) guidance in PCI of lesions involving coronary-artery branch points (bifurcations) improves clinical outcomes as compared with angiographic guidance is uncertain.

Methods: We conducted a multicenter, randomized, open-label trial at 38 centers in Europe.

Efficacy of coronary sinus Reducer in patients with refractory angina and diabetes mellitus.

Coronary sinus Reducer (CSR) implantation is currently recommended to relieve angina in patients with refractory symptoms despite optimal medical therapy and maximally achievable revascularization. The impact of diabetes mellitus on outcome after CSR implantation is at present unknown. We aimed to explore the impact of CSR in refractory angina patients with diabetes mellitus.

Efficacy of Coronary Sinus Reducer in Patients With Non-revascularized Chronic Total Occlusions.

The coronary sinus reducer (CSR) has been introduced as therapy for patients with refractory angina with no other treatment options. Aim of this study is to investigate the efficacy of the CSR in patients with refractory angina and presence of coronary chronic total occlusions (CTO). In this multicentre, international retrospective study, patients undergoing CSR implantation were screened and divided in 2 groups according to the presence/absence of CTO lesions.

A "minimalistic hybrid algorithm" in coronary chronic total occlusion revascularization: Procedural and clinical outcomes.

Background: Percutaneous recanalization of coronary chronic total occlusions (CTOs) traditionally relies on the use of dual-access and large bore catheters, with trans-femoral approach adoption in most cases.

Objectives: Aim of this manuscript is to describe the outcomes of an alternative hybrid algorithm, called "Minimalistic Hybrid Algorithm," which has the purpose to minimize the use of double access, large bore catheters, and femoral approach in order to minimize the risk of vascular complications and patient's discomfort, without compromising efficacy.

Methods: In this single-center registry, a "minimalistic" approach was attempted in consecutive patients undergoing CTO PCI between March 2016 and October 2017.

Implementing a minimally invasive approach (combining radial approach, small guiding catheters and minimization of double access) for coronary chronic total occlusion intervention according to the hybrid algorithm: The Minimalistic Hybrid Algorithm.

Percutaneous recanalization of coronary chronic total occlusions (CTOs) traditionally relies on the use of dual access and large bore catheters, with trans-femoral approach adoption in most of the cases. Aim of this manuscript is to describe an alternative algorithm, that we called "Minimalistic Hybrid Algorithm", in order to minimize the use of double access, large bore catheters, and femoral approach thus reducing patient's discomfort and possibly procedural complications. This algorithm can be interpreted as an evolution of the classic "Hybrid Algorithm" and requires the operator to be confident with all techniques known in this conventional algorithm.

First report of the use of long-tapered sirolimus-eluting coronary stent for the treatment of chronic total occlusions with the hybrid algorithm.

Background: Coronary chronic total occlusions (CTO) usually coexist with diffusely diseased coronary segments proximal and/or distal to the CTO segment. During percutaneous treatment of CTO, multiple overlapping stents are often needed to treat these long lesions.

Objectives: Aim of this study is to report the first use of long, tapered coronary sirolimus-eluting stents (SES) in this setting.

Rationale and design of POPular-TAVI: antiPlatelet therapy fOr Patients undergoing Transcatheter Aortic Valve Implantation.

Background: Despite improving experience and techniques, ischemic and bleeding complications after transcatheter aortic valve implantation (TAVI) remain prevalent and impair survival. Current guidelines recommend the temporary addition of clopidogrel in the initial period after TAVI to prevent thromboembolic events. However, explorative studies suggest that this is associated with a higher rate of major bleeding without a decrease in thromboembolic complications.

Relation between preoperative and intraoperative new wall motion abnormalities in vascular surgery patients: a transesophageal echocardiographic study.

Background: Coronary revascularization of the suspected culprit coronary lesion assessed by preoperative stress testing is not associated with improved outcome in vascular surgery patients.

Methods: Fifty-four major vascular surgery patients underwent preoperative dobutamine echocardiography and intraoperative transesophageal echocardiography. The locations of left ventricular rest wall motion abnormalities and new wall motion abnormalities (NWMAs) were scored using a seven-wall model.

Long-term outcome of ablative therapy of postoperative supraventricular tachycardias in patients with univentricular heart: a European multicenter study.

Background: Catheter ablation has evolved as a possible curative treatment modality for supraventricular tachycardias (SVT) in patients with univentricular heart. However, the long-term outcome of ablation procedures is unknown. We evaluated the procedural and long-term outcome of ablative therapy of late postoperative SVT in patients with univentricular heart.

Dose-dependent benefit of nitroglycerin on microcirculation of patients with severe heart failure.

Introduction: Microcirculatory abnormalities are frequently observed in patients with severe heart failure and correlate to worse outcomes. We tested the hypothesis that nitroglycerin dose-dependently improves perfusion in severe heart failure and that this could be monitored by measuring central-peripheral temperature gradient and with Sidestream Dark Field imaging of the sublingual mucosa.

Methods: A dose-response study was performed in 17 patients with cardiogenic shock (n = 9) or end-stage chronic heart failure (n = 8) admitted to Erasmus University Medical Center.
