Acute Changes in Mitral Annular Geometry After Transcatheter Edge-to-Edge Repair With PASCAL.

Background: Transcatheter edge-to-edge mitral valve repair (TEER) is an effective and safe method for treating high-risk patients with severe mitral regurgitation (MR). Two approved devices, MitraClip (Abbott Vascular) and PASCAL (Edwards Lifesciences), use leaflet approximation to reduce MR and may also influence annular dimensions via leaflet tension. The purpose of this study is to analyze the acute mitral annular dimensional changes following PASCAL implantation and correlate with long-term results.

Transcatheter valve repair of tricuspid regurgitation: 1-year outcomes from the TriCLASP study.

Background: Patients with tricuspid regurgitation (TR) are at high risk for morbidity and mortality, with poorer outcomes associated with increasing TR severity. Tricuspid transcatheter edge-to-edge repair (T-TEER) has emerged as a promising treatment option.

Aims: TriCLASP is a prospective, single-arm, European post-market study evaluating the safety and effectiveness of T-TEER with the PASCAL system to treat patients with ≥severe TR.

Early Outcomes of Real-World Transcatheter Tricuspid Valve Replacement.

Background: Transcatheter tricuspid valve replacement (TTVR) has been recently approved for the treatment of patients with severe tricuspid regurgitation (TR). Real-world evidence regarding the commercial use of TTVR is lacking.

Objectives: The aim of this study was to investigate the real-world safety and efficacy of the EVOQUE TTVR system in patients with severe TR treated at 12 experienced heart valve centers in 5 European countries.

Methods And Results: The International Registry of MitraClip in Acute Mitral Regurgitation following Acute Myocardial Infarction (IREMMI) includes 187 patients with severe MR post-MI managed with TEER. Of these, 176 were included in the analysis, 23 (13%) patients had acute papillary muscle rupture (PMR) and 153 (87%) acute secondary MR.

Percutaneous repair of moderate-to-severe or severe functional mitral regurgitation in patients with symptomatic heart failure: Baseline characteristics of patients in the RESHAPE-HF2 trial and comparison to COAPT and MITRA-FR trials.

Aim: The RESHAPE-HF2 trial is designed to assess the efficacy and safety of the MitraClip device system for the treatment of clinically important functional mitral regurgitation (FMR) in patients with heart failure (HF). This report describes the baseline characteristics of patients enrolled in the RESHAPE-HF2 trial compared to those enrolled in the COAPT and MITRA-FR trials.

Methods And Results: The RESHAPE-HF2 study is an investigator-initiated, prospective, randomized, multicentre trial including patients with symptomatic HF, a left ventricular ejection fraction (LVEF) between 20% and 50% with moderate-to-severe or severe FMR, for whom isolated mitral valve surgery was not recommended.

Severe functional ischaemic mitral regurgitation: is functional a misnomer for a dysfunctional valve? A case report.

Background: Mitral regurgitation (MR) in the context of left ventricular systolic dysfunction is often designated as functional, with emphasis on the underlying cardiomyopathy leading to malcoaptation of the 'otherwise normal valve'.

Case Summary: A 63-year-old male with ischaemic cardiomyopathy (left ventricular ejection fraction 20%) presented with intractable heart failure in need of inotropic support and could not be stepped down from an ICU hospital setting. Functional MR, graded as moderate on transthoracic echocardiography, was initially not considered as pertinent to the clinical condition and options discussed included initiation of dialysis for volume management, chronic inotropic support, and palliative measures.

The effect of Remote Ischemic Preconditioning (RIPC) on myocardial injury and inflammation in patients with severe aortic valve stenosis undergoing Transcatheter Aortic Valve Replacement (TAVΙ).

Background: Remote ischemic preconditioning (RIPC) is being evaluated as a strategy to reduce cardiac injury and inflammation in patients undergoing diverse cardiac invasive and surgical procedures. However, it is unclear whether RIPC has protective effects in patients undergoing the transfemoral- transcatheter aortic valve implantation (TF-TAVΙ) procedure.

Methods: Between September 2013 and September 2015, 55 random consecutive patients were prospectively assigned to receive SHAM preconditioning (SHAM, 22 patients) or Remote Ischemic Preconditioning (RIPC) (4 cycles of 5 min intermittent leg ischemia and 5 min reperfusion, 33 patients) prior to TF-TAVI.

Use of MitraClip for mitral valve repair in patients with acute mitral regurgitation following acute myocardial infarction: Effect of cardiogenic shock on outcomes (IREMMI Registry).

Objectives: To assess outcomes in patients with acute mitral regurgitation (MR) following acute myocardial infarction (AMI) who received percutaneous mitral valve repair (PMVR) with the MitraClip device and to compare outcomes of patients who developed cardiogenic shock (CS) to those who did not (non-CS).

Background: Acute MR after AMI may lead to CS and is associated with high mortality.

Methods: This registry analyzed patients with MR after AMI who were treated with MitraClip at 18 centers within eight countries between January 2016 and February 2020.

Emergency TAVI in a critically ill patient: A case report.

Transcatheter aortic valve implantation is a safe procedure even in inoperable patients with multi-organ failure and cardiogenic shock. In such cases, the heart team should be prepared to proceed to emergent implantation for timely and successful management of the patient.

MitraClip and left ventricular reverse remodelling: a strain imaging study.

Aims: The purpose of this study is to identify echocardiography predictors of clinical response and reverse left ventricular (LV) remodelling in patients with functional mitral regurgitation (FMR) treated with MitraClip.

Method And Results: We retrospectively analysed 86 high surgical risk patients with severe FMR; of those, 58 were implanted a MitraClip, and 28 received medical treatment and served as controls. At baseline and at 1-year follow-up, we performed clinical and echocardiography evaluation to assess global longitudinal strain (GLS) and myocardial work [global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE)].

Edge-to-edge mitral valve repair for acute mitral valve regurgitation due to papillary muscle rupture: a case report.

Background: Papillary muscle (PM) rupture is a devastating mechanical complication of myocardial infarction that leads to cardiogenic shock and death. In this case, we report a patient with acute mitral regurgitation due to PM rupture that was treated successfully with MitraClip.

Case Summary: An 85-year-old female patient with anterior ST-elevation myocardial infarction complicated with PM rupture and acute severe mitral regurgitation was admitted to our hospital.

Transcatheter Aortic Valve Replacement in a Patient With Dextrocardia and Situs Inversus Totalis.

This report presents the case of an 82-year-old man with known dextrocardia and situs inversus totalis who presented with increasing dyspnea on exertion and was diagnosed with severe aortic stenosis. Transcatheter aortic valve replacement was performed and required deviation from standard techniques for patients with normal anatomy and left-sided aortic arch. We describe two technical differences required for patients with dextrocardia and right-sided aortic arch that facilitate transcatheter aortic valve replacement in this patient group.

Compassionate use of the PASCAL transcatheter mitral valve repair system for patients with severe mitral regurgitation: a multicentre, prospective, observational, first-in-man study.

Background: Severe mitral regurgitation is associated with impaired prognosis if left untreated. Using the devices currently available, transcatheter mitral valve repair (TMVr) remains challenging in complex anatomical situations. We report the procedural and 30-day results of the first-in-man study of the Edwards PASCAL TMVr system.

Acute Invasive Hemodynamic Effects of Transcatheter Aortic Valve Replacement.

Background: Aortic stenosis imposes a chronic pressure overload on the left ventricle, with attendant adaptations in hemodynamics, muscle mass and performance. The hemodynamic changes that occur during the initial 24 h following abrupt removal of the impediment to left ventricular outflow have not been previously examined.

Methods: A total of 52 patients with right heart catheterization was evaluated before, within 6 h and at 24 h after successful transcatheter aortic valve replacement (TAVR).
