Uncommon presentation of bacteremia: A case study on aortic valve endocarditis.

, a HACEK organism, is one of five species known to less commonly cause infective endocarditis. This article presents a rare and noteworthy case of endocarditis affecting the aortic valve, seemingly unique when species in endocarditis were previously known to more commonly involve the pulmonic or mitral valves. In the setting of bacteremia, a 61-year-old male with no significant past medical history exhibited subtle systemic symptoms with a paucity of clinical signs associated with endocarditis and no evidence of embolic disease.

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.

A New Technique for the Treatment of Venous Popliteal Aneurysms Using the Axillary Vein: Medium and Long-Term Results.

Background: Venous popliteal aneurysms are a rare but serious disease due to the risk of pulmonary embolism (PE). Aneurysms larger than 20 mm in diameter or with an embolic episode should be treated. The classic surgical technique is the tangential resection of the aneurysm with venorrhaphy, which may raise the risk of recurrence.

Pulmonary Flow Modulation With Diabolo Stent Technique Over the Subpulmonary Outflow Tract.

The diabolo stent technique enables the controlled dilation of stenosis, improving blood flow while avoiding hyperflow. In our case, it was successfully applied to a young girl with a single-ventricle heart. This approach offers a valuable alternative to surgical treatment.

Preoperative interatrial block is associated with postoperative atrial fibrillation after cardiac surgery.

Objectives: Atrial fibrillation is common complication after heart surgery potentially leading to chronic atrial fibrillation, heart failure, and mortality. The aim of this study was to explore the relationship between preoperative interatrial block and the occurrence of postoperative atrial fibrillation.

Methods: Perioperative 12-channel ECGs of patients in sinus rhythm, scheduled for heart surgery including bypass and/or valve surgery were analysed.

Comparison of pulmonary and aortic root and cusp dimensions in normal adults using computed tomography: potential implications for Ross procedure planning.

Objectives: The Ross procedure is currently receiving renewed interest. Its function and durability depend on preservation of pulmonary valve anatomy; limited data exist on normal pulmonary valve geometry. The objective was to compare aortic and pulmonary root and cusp dimensions in adults with normal tricuspid aortic and pulmonary valves.

[Acute mitral regurgitation causing right-sided pulmonary edema: a case report].

A young female presented to our emergency department with sudden-onset shortness of breath and orthopnea. Her condition rapidly worsened. She developed severe respiratory failure and cardiogenic shock ensued.

Classical Ozaki Procedure in a Seven-Month-Old Infant.

We present a case study of neotricuspidization of the aortic valve with neocusp suturing based on templates similar to those used in the Ozaki procedure but adapted for infants. This is an alternative for patients when valve reconstruction is impossible or risky. A good postoperative hemodynamic outcome was obtained, but it is necessary to evaluate this approach on the basis of long-term results.

Racial and ethnic disparities in patients with severe tricuspid regurgitation: The Bronx-Valve registry.

Background: Severe tricuspid regurgitation (TR) is an adverse prognostic factor. The presence of potential racial/ethnic disparities in patient characteristics and outcomes remain unexplored. This study aimed to investigate the impact of race/ethnicity on the clinical course of severe TR.

Association of socioeconomic status with clinical characteristics, care quality and outcomes in patients undergoing transcatheter aortic valve implantation.

Background: Socioeconomic status (SES) is an important determinant of healthcare outcomes in many settings, but few studies have evaluated the impact of SES among patients with aortic stenosis (AS). We sought to explore the association between SES and clinical characteristics, care quality and outcomes among patients undergoing transcatheter aortic valve implantation (TAVI) for severe AS.

Methods: Consecutive patients undergoing TAVI for severe AS at three hospitals between August 2008 and February 2023 were prospectively enrolled in a multicentre registry.

Comparison of Immediate Outcomes of Pulmonary Valve-Sparing and Transannular Patch Techniques for Correction of Tetralogy of Fallot.

Objectives: This study primarily aimed to compare the mechanical ventilation durations between pulmonary valve-sparing and transannular patch repair techniques in the surgical correction of Tetralogy of Fallot. Secondary objectives included comparison of demographic characteristics, cardiopulmonary bypass parameters, postoperative vasoactive inotrope requirements, incidence of cardiac conduction abnormalities, echocardiographic findings, intensive care unit and hospitalisation durations, reoperations rates, morbidity and mortality between the 2 approaches.

Methods: This retrospective cohort study was conducted at the Royal Hospital, Muscat, Oman, between January 2016 and December 2019.

Assessing the Impact of Cardiac Output and Valve Orientation on Bioprosthetic Pulmonary Valve Hemodynamics Using In Vitro 4D-Flow MRI and High-Speed Imaging.

Purpose: Pulmonary valve replacement (PVR) using bioprosthetic valves is a common procedure performed in patients with repaired Tetralogy of Fallot and other conditions, but these valves frequently become dysfunctional within 15 years of implantation. The causes for early valve failure are not clearly understood. The purpose of this study was to explore the impact of changing cardiac output (CO) and valve orientation on local hemodynamics and valve performance.

Successful Use of Intraoperative Modified Valsalva Maneuver for Atrial Flutter Reversal in Pediatric Cardiac Surgery: Case Report and Review of Literature.

This case report describes the successful use of an intraoperative modified Valsalva maneuver to reverse atrial flutter in a pediatric patient with complex congenital heart disease undergoing systemic-to-pulmonary shunt surgery. The technique involved manipulating the Adjustable Pressure Limiting (APL) valve on the anesthesia machine to simulate the hemodynamic effects of the modified Valsalva maneuver, allowing for non-invasive management of supraventricular tachycardia without pharmacological intervention or electrical cardioversion. This intervention stabilized the patient's arrhythmia, maintaining hemodynamic stability throughout the procedure.

The prognostic value of the Dandel's index in patients undergoing tricuspid transcatheter edge-to-edge repair.

Aims: Conventional parameters of right ventricular (RV) function are load-dependent and therefore do not accurately reflect contractility in patients with relevant tricuspid regurgitation (TR). RV adaptability to load has been characterized using the Dandel's index in patients with heart failure, but its prognostic value in patients undergoing tricuspid transcatheter edge-to-edge repair (T-TEER) has not been investigated so far.

Methods And Results: From the EuroTR registry (2019 to 2022), patients with complete datasets and a minimum of 2-years of follow-up were included.

Hybrid Approach to Post-Radiation Valve Disease: Robotic Mitral Valve Replacement Alongside Transcatheter Aortic Valve Replacement.

A 63-year-old woman with history of mediastinal radiation was admitted for decompensated heart failure due to severe post-radiation aortic and mitral valve disease. To reduce cardiopulmonary bypass time and postoperative pulmonary complications, she underwent a hybrid approach with robotic mitral valve replacement and transcatheter aortic valve replacement.

The Essential Role of Ongoing Reassessment of Patients With Secondary Tricuspid Regurgitation.

This case report describes a patient diagnosed with severe secondary tricuspid regurgitation (TR) and pulmonary hypertension. Initial improvement with heart failure therapy was followed by a worsening of TR despite optimal medical management. Transcatheter edge-to-edge repair successfully addressed TR, resulting in marked clinical improvement.

Diagnosis and Management of Ventricular Septal Defects.

This review addresses the diagnosis and management of ventricular septal defects (VSDs). The VSDs are classified on the basis of their size, their number, and their location in the ventricular septum. Natural history of VSDs includes spontaneous closure, development of pulmonary hypertension, onset of infundibular obstruction, and progression to aortic insufficiency.
