Tricuspid Valve S-Curves and Chamber Views: Implications for Transcatheter Tricuspid and Pulmonary Valve Interventions, Part 2 of the S-Curves and Chamber Views Series.

Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve.

The impact of transcatheter aortic valve implantation (TAVI) on mitral regurgitation - a single center study.

Background: The coexistence of mitral regurgitation (MR) and severe aortic stenosis (AS) has been associated with worse outcomes in patients undergoing transcatheter aortic valve implantation (TAVI). Herein, the aim was to assess the etiology and degree of MR in an unselected TAVI population and investigate the impact of MR reduction at mid-term follow-up.

Methods: Patients subjected to TAVI as a treatment for severe AS in a single center were retrospectively analyzed.

A new perspective on aortic pressure for transcatheter closure of patent ductus arteriosus in the pediatric population.

Background: Hemodynamic assessment is not routinely performed when closing a patent ductus arteriosus (PDA). Significant PDA flow causes a drop in the aortic pressure distal to the shunt. Closure of PDA should increase distal systemic blood flow and significantly elevate distal aortic pressure, changing the systolic pressure gradient (ΔP) between the proximal and distal aorta.

Thrombin generation, fibrin clot permeation and lysis in patients with severe mitral regurgitation undergoing transcatheter edge-to-edge mitral valve repair: Mitral Fibrin Study.

Introduction: Intricate management of heart failure (HF), especially in the context of reduced ejection fraction, is further complicated by an elevated risk of thromboembolic events. Studies published so far offer inconclusive insight into the interplay between mitral regurgitation (MR) and the coagulation system.

Objectives: This study aimed to investigate the impact of transcatheter edge‑to‑edge repair (TEER) on specific coagulation parameters in HF patients.

What Do We Know So Far About Ventricular Arrhythmias and Sudden Cardiac Death Prediction in the Mitral Valve Prolapse Population? Could Biomarkers Help Us Predict Their Occurrence?

Purpose Of The Review: To summarize currently available data on the topic of mitral valve prolapse (MVP) and its correlation to the occurrence of atrial and ventricular arrhythmias. To assess the prognostic value of several diagnostic methods such as transthoracic echocardiography, transesophageal echocardiography, cardiac magnetic resonance, cardiac computed tomography, electrocardiography, and electrophysiology concerning arrhythmic episodes. To explore intra and extracellular biochemistry of the cardiovascular system and its biomarkers as diagnostic tools to predict rhythm disturbances in the MVP population.

The Prognostic Significance of Atrial Fibrillation and Left Atrium Size in Patients with Aortic Stenosis.

Aim    Aortic stenosis increases left atrial (LA) pressure and may lead to its remodeling. This can cause supraventricular arrhythmia. The aim of this study was to determine if the size of the LA and the presence of atrial fibrillation are related to the prognosis of patients with aortic stenosis.

Right ventricle to pulmonary artery coupling as a predictor of perioperative outcome in patients with secondary mitral valve insufficiency.

Background: The aim of the study was to assess some parameters of right ventricle (RV) function as predictors of short-term mortality in patients with severe secondary mitral regurgitation (SMR) after mitral valve surgery.

Methods: We conducted a retrospective analysis of 112 consecutive patients with severe SMR who had undergone mitral valve repair or replacement with or without concomitant coronary artery bypass surgery. We assessed RV to pulmonary artery coupling by calculating the ratio of tricuspid annular plane systolic excursion (TAPSE) to non-invasively estimated RV systolic pressure (RVSP).

The usefulness of echo-based hemodynamic parameters in cardiac resynchronization therapy with conduction system pacing for optimal device programing.

Background: His bundle pacing (HBP) has proved to be a valuable alternative enabling the physiological activation of cardiac contraction in cardiac resynchronization therapy (CRT). At present, however, little is known about the optimal method of programming of the His bundle-paced CRT systems in terms of achieving the best cardiac output.

Aim: The aim of this study was to evaluate the impact of cardiac resynchronization therapy with conduction system pacing (CRT+CSP) on echo-based hemodynamic parameters in the early post-operative measurements.

Hemodynamic parameters of aortic valve prostheses - KRAK-AS registry analysis.

Introduction: The treatment of choice for aortic stenosis is a valve replacement. Some patients have post-procedural increased pressure gradient on the implanted prosthesis because of patient-prosthesis mismatch (PPM), known to adversely influence prognosis. The PPM risk should be initially predicted and effort made to avoid this complication, specifically in large body size patients.

Right ventricular-pulmonary arterial coupling in patients with implanted left ventricular assist devices.

Objective: Both the right ventricular (RV) contractile function and pulmonary arterial (PA) pressure influence clinical outcomes in patients supported with left ventricular assist devices (LVADs), but the impact of RV-PA coupling is unknown. This study aimed to determine the prognostic impact of RV-PA coupling in patients with implanted LVADs.

Methods: Patients with implanted third-generation LVADs were retrospectively enrolled.

Preoperative and mid-term right ventricular systolic function assessment, at rest and during exercise, with speckle-tracking echocardiography after left ventricular assist device implantation.

Objectives: The study aimed to compare pre- and postoperative resting as well as postprocedural resting and exertional right ventricular speckle-tracking echocardiographic parameters at a mid-term follow-up after left ventricular assist device (LVAD) implantation.

Methods: Patients with implanted third-generation LVADs with hydrodynamic bearings were prospectively enrolled (NCT05063006). Myocardial deformation was evaluated before pump implantation and at least three months after the procedure, both at rest and during exercise.

THE DIETARY HABITS AND NUTRITION BELIEFS OF PATIENTS WITH AORTIC STENOSIS.

Objective: Aim: The analysis of dietary knowledge and habits of patients with aortic stenosis, both prior to and post valve implantation.

Patients And Methods: Materials and methods: Patient with diagnosed moderate or severe aortic stenosis were included into the study. Telephonic dietary interview was performed.
