Valve-sparing procedure for acute aortic regurgitation due to intimal intussusception in a minimally localized aortic root dissection.

Background: Acute heart failure due to aortic regurgitation (AR) is a severe comorbidity of type A acute aortic dissection (AAD). Valve-sparing aortic root replacement is typically performed when the aortic valve remains intact.

Case Presentation: A 33-year-old male presented to our hospital with chest pain.

A rapid deployment valve option for failing Medtronic Freestyle full root: a single centre experience.

Background: There are several high-risk treatment options for valve failure of a biological full root replacement. When tailoring the best treatment option for the patient, implantation of a rapid deployment valve (RDV) should be considered.

Case Presentation: Six patients presented with aortic regurgitation in a full root Freestyle bioprosthesis.

Recurrent strokes after transcatheter aortic valve replacement in an elderly patient with severe bicuspid aortic valve stenosis: a case report.

Background: Transcatheter aortic valve replacement (TAVR) has evolved from a novel technology to an established therapy for high-risk patients with symptomatic severe aortic valve stenosis (AS). Recently, its use has also been extended to low-risk patients, resulting in its increasing utilization in patients with bicuspid aortic valve (BAV). But as a serious post-TAVR complication, ischemic stroke was associated with a nearly 6-fold increased 30-day mortality.

A technique avoiding cardioplegia delivery complications: a case using systemic hyperkalemia cardiopulmonary bypass combined with circulatory arrest.

We conducted a high-risk redo mitral valve replacement through a right mini-thoracotomy without rib spreading (redo-MICS MVR) under systemic hyperkalemia combined with circulatory arrest to circumvent complications associated with cardioplegia delivery. The patient, a 75-year-old man, had a predicted mortality rate of 20%. Initial antegrade cardioplegia successfully induced cardiac arrest, which was administered every 30 min.

Hemodynamic evaluation of the pulmonary arteries and aorta using 4D flow cardiac MRI in children and young adults with dextro-transposition of the great arteries after the arterial switch operation.

Background: Pulmonary artery stenosis, neoaortic dilatation, and neoaortic valve insufficiency are among the most frequent complications of the arterial switch operation for repair of dextro-transposition of the great arteries (d-TGA). It remains difficult to predict which patients will require great arterial reintervention.

Objective: We aimed to characterize hemodynamics within the great arteries using 4D flow MRI in patients with d-TGA after the arterial switch operation.

The Ross procedure for recurrently failed aortic valve procedures.

The Ross procedure provides young patients with unrepairable aortic valve disease with a living pulmonary autograft that confers significant survival benefit and improved quality of life. However, the procedure is complicated, and surgeons can be reluctant to offer it as a solution, especially in complex re-operative scenarios. We present a young patient with symptomatic, severe aortic insufficiency who had undergone two failed aortic valve procedures for congenital bicuspid aortic valve disease within the prior year.

An Echocardiographic Study of a Rare Cause of Mitral Regurgitation: Hypoplastic Posterior Mitral Valve Leaflet.

Background: The precise etiology of hypoplasia of the posterior mitral valve leaflet (PMVL) remains incompletely elucidated; however, it has been hypothesized to stem from genetic mutations occurring during fetal development. Herein, we present the anatomical characteristics of the mitral valve and associated cardiac pathologies in patients with hypoplastic PMVL.

Methods: This single-center retrospective study involved patients who presented between 2015 and 2021 at a tertiary healthcare facility.

Endocarditis and ascending aortic aneurysm with aortic valve insufficiency secondary to late syphilis: Case report.

Venereal syphilis, caused by Treponema pallidum, is a major global health problem. Untreated latent syphilis can progress to tertiary syphilis, often leading to severe complications such as cardiac involvement, particularly syphilitic aortitis, which may manifest decades after the initial infection. We present a case of a 46-year-old woman who developed an ascending aortic aneurysm and severe aortic valve insufficiency due to late-stage syphilis.

Point-of-care ultrasound diagnosis of acute valvular emergencies.

Introduction: Acute valvular emergencies, a time-sensitive diagnosis, are nearly impossible to diagnose without ultrasound, and missing the diagnosis can significantly impact patient outcomes. Many emergency physicians lack access to echo technicians and may be uncomfortable performing the ultrasound themselves. Approaching the paucity of review articles, none of which are focused for the emergency physician, can be quite daunting, even for those with extensive ultrasound training.

Transcatheter aortic valve implantation in patient with combined aortic and subaortic membrane stenosis: a case report.

Background: The combination of symptomatic aortic stenosis (AS) and subaortic membrane (SAM) is rare, and the haemodynamic consequences of this combination are challenging to diagnose and manage.

Case Summary: We present the case of a 78-year-old male who presented with symptomatic AS and chronic heart failure. On echocardiography, the combination of AS and SAM was diagnosed.

The Value of Repeat 5-HIAA Measurements as a Predictor of Carcinoid Heart Disease: A Prospective 5-Year Follow-Up Study in Patients with Small Intestinal Neuroendocrine Tumors.

Small intestinal neuroendocrine tumors (SI-NETs) are characterized by carcinoid syndrome and carcinoid heart disease (CHD). The aim of the present study was to identify early risk markers for carcinoid heart disease and survival in a prospective median-term follow-up setting. We measured 5-HIAA and cumulative 5-HIAA exposure (Cum-5-HIAA) based on repeated measurements, proBNP, vascular function, hepatic tumor load, and transthoracic echocardiography (TTE) at baseline and during the median 5-year follow-up.

A 63-year-old man was diagnosed with myelodysplastic syndrome (MDS) at the age of 62 by the hematology department. The patient underwent four cycles of azacitidine (AZA) therapy, followed by successful bone marrow transplantation (BMT). Subsequently, he was hospitalized twice for graft-versus-host disease (GVHD).

Lifetime management considerations to optimise transcatheter aortic valve implantation: a practical guide.

Transcatheter aortic valve implantation (TAVI) is a safe and effective procedure for the treatment of aortic stenosis. With the recently broadened indications, there is a larger cohort of patients likely to outlive their first transcatheter heart valve (THV). This review discusses relevant lifetime planning considerations, focusing on the utility of preprocedural computed tomography imaging to help implanters future-proof their patients who are likely to outlive their first valve.

Transcatheter aortic valve replacement-in-transcatheter aortic valve replacement for high-risk anatomies: demonstrating the feasibility of index leaflet overhang in a first-in-human case report.

Background: Transcatheter aortic valve replacement (TAVR)-in-TAVR within index supra-annular transcatheter heart valves (THVs) and high-risk anatomy can compromise coronary perfusion and re-access.

Case Summary: An 80-year-old male presented with acute heart failure caused by degeneration of an Evolut R THV, leading to severe aortic regurgitation. Aortic computed tomography imaging revealed a high-risk anatomy characterized by the index THV's commissural plane being placed above the coronary ostia and a valve-to-aorta distance of less than 2 mm, resulting not eligible for redo-TAVR according to recent literature.

[Prevalence and evolution of left ventricular insufficiency in patients undergoing severe aortic insufficiency].

Introduction: Aortic insufficiency (AR) evolves during follow-up with dilation of the left chambers and eventually with deterioration of the ejection fraction (EF). Treatment as well as evolution of EF after the procedure remains uncertain. The objective of the following work was to establish the prevalence of ventricular dysfunction and evaluate the evolution of EF at 6 months in patients with aortic valve replacement (AVR) due to AR.
