heart valve surgery

Severe tricuspid regurgitation (TR) is a progressive condition associated with substantial morbidity, poor quality of life, and increased mortality. Patients with TR commonly have coexisting conditions including congestive heart failure, pulmonary hypertension, chronic lung disease, atrial fibrillation, and cardiovascular implantable electronic devices, which can increase the complexity of medical and surgical TR management. As such, the optimal timing of referral for isolated tricuspid valve (TV) intervention is undefined, and TV surgery has been associated with elevated risk of morbidity and mortality...

There is a broad spectrum of mitral valve diseases ranging from young patients with rheumatic mitral valve stenosis up to older patients with secondary mitral valve regurgitation and numerous comorbidities. A profound understanding of the etiology, anatomical characteristics of mitral valve diseases and current treatment options is necessary to be able to prepare a patient-centered treatment approach. The interdisciplinary collaboration of referring physicians, interventional cardiologists, cardiac surgeons, heart failure and imaging specialists as well as anesthesiologists is a cornerstone of optimal patient treatment...

In this case report, we present the unique and intriguing case of a 57-year-old man who experienced exertional palpitations and shortness of breath for 5 years. He was diagnosed with idiopathic heart failure three years ago, leading to diuretic treatment. Physical examination revealed notable left lower extremity swelling, severe varicose veins, and cardiac murmurs. Echocardiography showed significant cardiac enlargement and severe functional mitral and tricuspid valve regurgitation. Computed tomography (CT) imaging uncovered a 10 mm left common iliac arteriovenous fistula, causing abnormal early filling of the inferior vena cava (IVC) and marked IVC dilation...

INTRODUCTION: This study aimed to compare postoperative outcomes after cardiac surgery in solid-organ transplant recipients and nontransplant patients. METHODS: We performed a retrospective analysis of 78 consecutive transplant recipients who underwent cardiac surgery at Asan Medical Center between 2000 and 2022 and were matched with 312 nontransplant patients who underwent cardiac surgery at a 1:4 ratio. The outcomes included 30-day mortality, all-cause death, cardiac death, readmission, and cardiac readmission...

BACKGROUND: Fungal endocarditis is a rare but serious condition associated with high mortality rates. Various predisposing factors contribute to its occurrence, such as underlying cardiac abnormalities, cardiac surgeries, prosthetic cardiac devices, and central venous catheters. Diagnosing fungal endocarditis, particularly Aspergillus, poses challenges, often complicated by negative blood cultures. CASE PRESENTATION: This report details a case of extensive ascending aorta involvement in Aspergillus endocarditis (AE) in a 24-year-old man with a history of bioprosthesis aortic valve replacement (AVR)...

OBJECTIVES: Although risk factors for unsuccessful Maze procedure have been demonstrated, an appropriate patient selection is still controversial. In our institute, Maze procedure is indicated for those whom normal sinus rhythm (NSR) was reestablished by intraoperative direct cardioversion (DC) after ventricular unloading by total cardiopulmonary bypass. The purpose of this study was to evaluate the effectiveness of our indication criteria for Maze procedure in patients with mitral valve disease...

BACKGROUND: RBT-1 is a combination drug of stannic protoporfin (SnPP) and iron sucrose (FeS) that elicits a preconditioning response through activation of antioxidant, anti-inflammatory, and iron-scavenging pathways, as measured by heme oxygenase-1 (HO-1), interleukin-10 (IL-10), and ferritin, respectively. Our primary aim was to determine whether RBT-1 administered before surgery would safely and effectively elicit a preconditioning response in patients undergoing cardiac surgery. METHODS: This phase 2, double-blind, randomised, placebo-controlled, parallel-group, adaptive trial, conducted in 19 centres across the USA, Canada, and Australia, enrolled patients scheduled to undergo non-emergent coronary artery bypass graft (CABG) and/or heart valve surgery with cardiopulmonary bypass...

This study evaluated nationwide associations between concomitant left atrial appendage clip (LAAC) placement during cardiac surgery and postoperative outcomes. We identified 1,260,999 patients who underwent coronary artery bypass grafting, valve, and aortic surgeries in the 2016-2020 Nationwide Readmissions Database and stratified by concomitant LAAC versus no-LAAC placement. Patients who underwent surgical ablation were excluded. Mortality and complications were compared during index admissions and for patients readmitted within 30 and 90 days of the index discharge date for unmatched and propensity score matched (PSM) groups...

The tricuspid valve is known as "the forgotten valve". Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease. TR is often late in the course of the disease when it becomes symptomatic, often being a marker of late-stage chronic heart failure with a poor prognosis and high mortality rate at long-term follow-up. Despite the clear correlation between TR and mortality, most TR patients are under-treated. Neither pharmacologic nor surgical treatment demonstrates a significant survival benefit...

Transcatheter tricuspid valve intervention (TTVI) has recently emerged as a promising alternative to surgery for tricuspid regurgitation (TR). However, a significant proportion of patients fail screening for TTVI, and little is known about their characteristics and natural history. This study sought to investigate causes of screen failure and outcomes of patients declined for TTVI. This was a retrospective single-center study of 32 patients who were ineligible for participation in TTV replacement (TTVR) and tricuspid transcatheter edge-to-edge repair (T-TEER) trials...

PURPOSE: To assess in-hospital mortality and complication rates after radical cystectomy (RC) in patients with history of heart-valve replacement. MATERIALS AND METHODS: Using the National Inpatient Sample (2000-2019), non-metastatic bladder cancer patients undergoing RC were stratified according to history of heart-valve replacement. Regression models (RM) predicted hospital outcomes. RESULTS: Of 25,535 RC patients, 250 (1.0%) harbored history of heart-valve replacement...

OBJECTIVES: Using the cardiac surgery database is of high importance in referral centers and can lead to a better quality of care for patients. Tehran Heart Center (THC) is a cardiovascular referral center that was inaugurated in 2001. In this report, we aimed to present the third report of trends in patients' cardiovascular risk factors and surgical procedures from 2002 to 2021 that have been gathered for all THC patients. METHODS: This serial cross-sectional study was conducted at Tehran Heart Center from 2002 to 2021...

BACKGROUND: Severe tricuspid regurgitation (TR) adversely affects long-term survival; however, isolated tricuspid valve (TV) surgery has been rarely performed due to high operative mortality. In addition, the previous literature included heterogeneous TR etiologies. Therefore, we aimed to elucidate early and long-term outcomes of isolated TV surgery for functional TR. METHODS: An electronic search was performed to identify all relevant studies. Baseline characteristics, perioperative variables, and clinical outcomes were extracted and pooled for meta-analysis...

BACKGROUND: Reports of cardiac operations after transcatheter aortic valve replacement (TAVR) and early TAVR explantation are increasing. The purpose of this report is to document trends and outcomes of cardiac surgery following initial TAVR. METHODS: The Society of Thoracic Surgeons Adult Cardiac Surgery Database was queried for all adult patients undergoing cardiac surgery after a previously placed TAVR between January 2012 and March 2023. This identified an overall cohort, as well as two subcohorts: non aortic valve surgeries, and surgical aortic valve replacement (SAVR) after previous TAVR...

BACKGROUND: Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are rare tumors, often diagnosed in an advanced stage when curative treatment is impossible and grueling symptoms related to vasoactive substance release by tumor cells affect patients' quality of life. Cardiovascular complications of GEP-NENs, primarily tricuspid and pulmonary valve disease, and right-sided heart failure, are the leading cause of death, even compared to metastatic disease. CASE SUMMARY: We present a case of a 35-year-old patient with progressive dyspnea, back pain, polyneuropathic leg pain, and nocturnal diarrhea lasting for a decade before the diagnosis of neuroendocrine carcinoma of unknown primary with extensive liver metastases...

INTRODUCTION AND IMPORTANCE: Intracranial dermoid cysts (IDC) are defined as rare, slow-growing cystic congenital neoplasms. Rupture of an intracranial dermoid cyst occurs rarely and most often spontaneously and results in potentially serious symptoms. CASE PRESENTATION: A39-year-old female, with mechanical prosthetic heart valve presented with history of headache for 10 months and generalized tonicoclonic seizures. On the admission, the patient had a normal neurological and cranial nerve exam...

BACKGROUND: Mechanical heart valve replacement is a standard treatment for severe valvular disorders. The use of mono-leaflet valves has decreased recently. Recognizing the echocardiographic features of mono-leaflet and bileaflet valves is crucial for accurate complication diagnosis and proper management. CASE PRESENTATION: A 65-year-old female with mono-leaflet mitral and bileaflet tricuspid valves underwent an echocardiographic assessment. This simple educational case provides a unique opportunity to compare the echocardiographic features of these valves within a single patient...

INTRODUCTION: Carcinoid heart disease (CHD), a complication of carcinoid syndrome (CS), is a rare condition that can lead to right sided valvular heart disease and has been traditionally associated with a poor prognosis. We conducted a systematic review and meta-analysis to explore the accuracy of biomarkers and echocardiography in diagnosing CHD amongst patients who are already known to have neuroendocrine tumours and to assess whether surgical management of CHD leads to a reduction in mortality...
