Chronic Total Occlusions in Non-Infarct-Related Coronary Arteries and Long-Term Cardiovascular Mortality in Patients Receiving Percutaneous Coronary Intervention in Acute Coronary Syndromes.

: Patients with non-infarct-related artery chronic total occlusion (non-IRA CTO) found during percutaneous coronary intervention (PCI) in acute coronary syndromes (ACSs) are not rare and have worse clinical outcomes. We aimed to analyze their long-term clinical outcomes in regard to clinical characteristics, revascularization strategies, and adherence to medical therapy. : The dual-center ACS registry of patients treated from Jan 2017 to May 2023 was used to identify 1950 patients with timely PCI in ACS who survived to discharge with documented adequate demographic, clinical, and angiographic characteristics, treatment strategies, and medical therapy adherence during a median follow-up time of 49 months.

Myocardial deposition of aluminum, arsenic, cadmium, and lead accelerates heart failure and alters UPRmt in humans.

In the myocardium of control subjects and patients undergoing heart transplantation or left ventricular assist device implantation (LVAD), we analyzed concentrations of Al, As, Cd, Pb, and Ni using inductively coupled plasma mass spectrometry. Myocardial generation of oxidative-stress-induced lipid peroxidation was analyzed by quantifying concentration of 4-Hydroxynonenal (4-HNE) with ELISA and pro-apoptotic DAPK2 gene expression was determined with quantitative RT-PCR. Compared to six control hearts, myocardial samples of 128 individuals undergoing heart transplantation or LVAD implantation exhibited a moderate increase in deposition of five tested non-essential elements, which was significantly increased only for Cd and cumulative deposition of Al, As, Cd, and Pb.

Cardiotoxicity of Iron and Zinc and Their Association with the Mitochondrial Unfolded Protein Response in Humans.

This study was designed to examine the association between myocardial concentrations of the trace elements Cu, Fe, Mn, Mo, and Zn and the expression of mitochondrial unfolded protein response (UPRmt) elements and the age of patients who received heart transplantation or a left-ventricular assist device (ageHTx/LVAD). Inductively coupled plasma mass spectrometry was used to determine the concentration of Cu, Fe, Mn, Mo, and Zn in the myocardium of control subjects and patients undergoing heart transplantation or left-ventricular assist device (LVAD) implantation. We used ELISA to quantify the expression of UPRmt proteins and 4-Hydroxynonenal (4-HNE), which served as a marker of oxidative-stress-induced lipid peroxidation.

Low Level of First Morning Urine Cardiac Troponin I: A Specific Hallmark of Aortic Stenosis Severity.

: It has recently been shown that cardiac-specific troponin I concentrations in first morning urine samples can be measured with commercially available tests. Due to their accumulation in the first morning urine, scientific papers indicate a potential predictive value for cardiovascular diseases. Therefore, the aim of this study was to compare the concentration of cardiac troponin I in the first morning urine in patients with severe aortic stenosis and the healthy population.

Outcomes of Patients with Normal LDL-Cholesterol at Admission for Acute Coronary Syndromes: Lower Is Not Always Better.

Background And Aim: There are few prospective data on the prognostic value of normal admission low-density lipoprotein cholesterol (LDL-C) in statin-naïve patients with acute coronary syndromes (ACS) who are treated with a preemptive invasive strategy. We aimed to analyze the proportion of patients with normal LDL-C at admission for ACS in our practice, and their characteristics and clinical outcomes in comparison to patients with high admission LDL-C.

Patients And Methods: Two institutions' prospective registries of patients with confirmed ACS from Jan 2017 to Jan 2023 were used to identify 1579 statin-naïve patients with no history of prior coronary artery disease (CAD), and with available LDL-C admission results, relevant clinical and procedural data, and short- and long-term follow-up data.

Aortic Valve Repair with External Annuloplasty in Bicuspid versus Tricuspid Aortic Valve Patients.

Surgical repair for regurgitant bicuspid aortic valve (BAV) is promising but underutilized due to perceived complexities and lack of long-term data. This study evaluated the efficacy of valve-sparing root remodeling (VSRR) or isolated valve repair combined with calibrated external ring annuloplasty in BAV versus tricuspid aortic valve (TAV) patients. All patients operated on for aortic regurgitation and/or aneurysm at our institution between 2014 and 2022 were included and entered into the Aortic Valve Insufficiency and ascending aorta Aneurysm InternATiOnal Registry (AVIATOR).

Enterobacter cloacae septicemia in a triple-cannula extracorporeal membrane oxygenation circulatory support treated with Seraph-100 Microbind affinity blood filter.

Bloodstream infections (BSI) are frequently encountered during extracorporeal membrane oxygenation (ECMO) support. Once septicemia is observed, treatment should be rapid, adequate, and multifaceted, particularly in advanced ECMO configurations. We report on a case of a 60-year-old male patient with acute-on-chronic heart failure due to ischemic cardiomyopathy.

Aortic Valve Repair and Early-Career Surgeons-Nothing Is Impossible.

Aortic valve repair with either the reimplantation of the aortic valve or aortic root remodelling with the external annuloplasty procedure is the most effective means of treating aortic regurgitation and/or aortic root aneurysms [...

A multicentre, propensity score matched analysis comparing a valve-sparing approach to valve replacement in aortic root aneurysm: Insight from the AVIATOR database.

Objectives: Our goal was to evaluate the outcome of valve-sparing root replacement (VSRR) and to compare the outcomes to those of patients having composite valve-graft conduit aortic root replacement (CVG-ARR) in a cohort of patients with aortic root aneurysm ± valve insufficiency, without valvular stenosis. Although valve-sparing procedures are preferable in young patients, there is a lack of comparative data in comparable patients.

Methods: The VSRR procedures were performed in 2005 patients, and 218 patients underwent a CVG-ARR procedure.

Indications, Complications, and Outcomes of Cardiac Surgery After Heart Transplantation: Results From the Cash Study.

Background: Allograft pathologies, such as valvular, coronary artery, or aortic disease, may occur early and late after cardiac transplantation. Cardiac surgery after heart transplantation (CASH) may be an option to improve quality of life and allograft function and prolong survival. Experience with CASH, however, has been limited to single-center reports.

Comparison between OPCABG and CABG Surgical Revascularization Using Transit Time Flow Measurement (TTFM).

Objective: To compare the intraoperative quality of coronary anastomoses performed with or without cardiopulmonary bypass using transit time flow measurement (TTFM) parameters.

Methods: We collected data from 588 consecutive patients who underwent surgical revascularization. We retrospectively reviewed data from two groups: 411 with cardiopulmonary bypass (CABG group) and 177 off-pump (OPCABG group).

Trying to Survive A Serious Heart Condition in Time of COVID-19.

The world has suffered over the past year under COVID-19. Unfortunately, people still are getting sick from other, also severe, diseases. Although the COVID-19 infection is present, patients need treatment for other life-threatening conditions.

Results of frozen elephant trunk from the international E-vita Open registry.

Background: Over the years, frozen elephant trunk (FET) has become the treatment of choice for multisegmental thoracic aortic disease. This multicenter study presents the evolution of FET results using the E-vita Open hybrid graft with respect to institutional experience and time.

Methods: The data of International E-vita Open registry were studied according to the institutional experience of the participating centers (high- versus low-volume centers) and according to the evolution of FET treatment during time (1 period, 2005-2011 versus 2 period, 2012-2018).

A Case of Postoperative Covid-19 Infection After Cardiac Surgery: Lessons Learned.

While the focus of the medical community is on the management of COVID-19 and its associated complex presentations, it is critical to recognize that patients will continue to present with other medical problems that require urgent therapeutic interventions. There is growing concern that such interventions might have an impact on the natural history of COVID-19. We present a case of a patient who presented with unstable angina and multivessel coronary artery disease for which coronary artery bypass surgery was indicated and performed.

The epidemiological and clinical features of odontogenic infective endocarditis.

Antibiotic prophylaxis (AP) of infective endocarditis (IE) in dental practice is a controversial topic. We evaluated the characteristics of the odontogenic IE and assessed the practice and sources of information pertaining to the topic utilized by the Croatian dentists. We conducted a retrospective review of consecutive medical charts of adult patients with IE, admitted to the University Hospital for Infectious Diseases in Zagreb, Croatia, between January 2007 and December 2017.

Primary Left Atrial Angiosarcoma Presenting as Acute Coronary Syndrome.

Primary cardiac neoplasms are extremely rare and often overlooked as differential diagnosis. Angiosarcomas are the most common primary malignant neoplasms of the heart often with nonspecific symptoms. We present a 43-year-old woman admitted to our hospital with chest pain and inferoposterolateral myocardial infarction.

The Dark Side of the Heart: Cardiovascular Manifestation of Ochronosis.

Alkaptonuria is rare genetic disorder of tyrosine metabolism manifesting with signs of tissue pigmentation, dark urine, and ochronotic arthropathies. Commonly undiscovered by late adulthood, alkaptonuria can manifest as cardiac ochronosis with cardiovascular disorders such as valvulopathies, but rarely coronary artery disease. This case report describes 2 patients with aortic stenosis and coronary artery disease in whom alkaptonuria was diagnosed during open heart surgery.

Association between Circulatory and Plaque Resistin Levels with Carotid Plaque Instability and Ischemic Stroke Events.

Unlabelled: ses of ischemic stroke. The risk of ischemic stroke increases with the degree of carotid stenosis and plaque vulnerability. The aim of this study was to investigate the association of circulating and plaque resistin levels with plaque vulnerability and ischemic stroke events in patients with moderate- to high-grade carotid artery stenosis.

Heart re-transplantation in Eurotransplant.

Internationally 3% of the donor hearts are distributed to re-transplant patients. In Eurotransplant, only patients with a primary graft dysfunction (PGD) within 1 week after heart transplantation (HTX) are indicated for high urgency listing. The aim of this study is to provide evidence for the discussion on whether these patients should still be allocated with priority.

LETTER TO THE EDITOR.

Quadruple-valve infective endocarditis caused by Abiotrophia defectiva.

Quadruple-valve endocarditis is a challenging condition, for which there is limited treatment experience and poor overall survival. We report the first case caused by Abiotrophia defectiva that has been surgically treated both with the replacement of the aortic and pulmonary valves and the repair of the mitral and tricuspid valves with a good outcome. The patient's clinical course is described and a review of literature on this rare causative agent is given.

Isolated Tricuspid Valve Libman-Sacks Endocarditis in Systemic Lupus Erythematosus with Secondary Antiphospholipid Syndrome.

Libman-Sacks endocarditis, one of the most prevalent cardiac presentations of systemic lupus erythematosus, typically affects the aortic or mitral valve; tricuspid valve involvement is highly unusual. Secondary antiphospholipid syndrome increases the frequency and severity of cardiac valvular disease in systemic lupus erythematosus. We present the case of a 47-year-old woman with lupus and antiphospholipid syndrome whose massive tricuspid regurgitation was caused by Libman-Sacks endocarditis isolated to the tricuspid valve.

Letter from the Editor-in-Chief.

It was in the mid-nineties when a senior colleague of mine, Dr. Bojan Biocina, introduced me to something called "OpenHeart-L" on The Heart Surgery Forum website. Suddenly, a whole new world appeared in front of me! The possibility to communicate with colleagues from all around the globe was amazing.
