Abstract
Coronary artery disease continues to be the leading cause of morbidity and mortality worldwide. Recent clinical trials have not demonstrated any mortality benefit of percutaneous coronary intervention compared to medical management alone in the treatment of stable angina. While invasive coronary angiography remains the gold standard for diagnosing coronary artery disease, it comes with significant risks, including myocardial infarction, stroke and death. There have been significant advances in imaging techniques to diagnose coronary artery disease in haemodynamically stable patients. The latest National Institute for Health and Care Excellence and European College of Cardiology guidelines emphasise the importance of using these imaging techniques first to inform diagnosis. This review discusses these guidelines and imaging techniques, alongside their benefits and drawbacks.

Detection of increased pyruvate dehydrogenase flux in the human heart during adenosine stress test using hyperpolarized [1- 13C]pyruvate cardiovascular magnetic resonance imaging. J Cardiovasc Magn Reson 2022; 24:34. [PMID: 35658896 PMCID: PMC9169396 DOI: 10.1186/s12968-022-00860-6] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 03/29/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Hyperpolarized (HP) [1-13C]pyruvate cardiovascular magnetic resonance (CMR) imaging can visualize the uptake and intracellular conversion of [1-13C]pyruvate to either [1-13C]lactate or 13C-bicarbonate depending on the prevailing metabolic state. The aim of the present study was to combine an adenosine stress test with HP [1-13C]pyruvate CMR to detect cardiac metabolism in the healthy human heart at rest and during moderate stress. METHODS A prospective descriptive study was performed between October 2019 and August 2020. Healthy human subjects underwent cine CMR and HP [1-13C]pyruvate CMR at rest and during adenosine stress. HP [1-13C]pyruvate CMR images were acquired at the mid-left-ventricle (LV) level. Semi-quantitative assessment of first-pass myocardial [1-13C]pyruvate perfusion and metabolism were assessed. Paired t-tests were used to compare mean values at rest and during stress. RESULTS Six healthy subjects (two female), age 29 ± 7 years were studied and no adverse reactions occurred. Myocardial [1-13C]pyruvate perfusion was significantly increased during stress with a reduction in time-to-peak from 6.2 ± 2.8 to 2.7 ± 1.3 s, p = 0.02. This higher perfusion was accompanied by an overall increased myocardial uptake and metabolism. The conversion rate constant (kPL) for lactate increased from 11 ± 9 *10-3 to 20 ± 10 * 10-3 s-1, p = 0.04. The pyruvate oxidation rate (kPB) increased from 4 ± 4 *10-3 to 12 ± 7 *10-3 s-1, p = 0.008. This increase in carbohydrate metabolism was positively correlated with heart rate (R2 = 0.44, p = 0.02). CONCLUSIONS Adenosine stress testing combined with HP [1-13C]pyruvate CMR is feasible and well-tolerated in healthy subjects. We observed an increased pyruvate oxidation during cardiac stress. The present study is an important step in the translation of HP [1-13C]pyruvate CMR into clinical cardiac imaging. Trial registration EUDRACT, 2018-003533-15.

Abstract
Surgical ventricular remodeling (SVR) is an invasive method of treating patients with heart failure who also have ischemic cardiomyopathy and reduced ejection fraction (EF). Introduced in the mid-1980s, this technique was met with varying success and relatively high morbidity and mortality despite its theoretical benefits. The development of the BioVentrix Revivent TC System (BioVentrix, Inc., San Ramon, CA) as a less-invasive method of surgical ventricular remodeling has created a novel, multidisciplinary approach to heart failure management, which necessitates multiple subspecialties. Currently in the trial phase in the United States and widely used in Europe, the positive results to date appear promising for the rapid adoption of this procedure. For the cardiac anesthesiologist, a thorough understanding of the patient population, procedural goals, and intraoperative management is essential. This overview discusses the advancement in surgical ventricular remodeling, the pertinent surgical steps of the BioVentrix Revivent TC System placement, and specific anesthetic considerations for this novel procedure.

Abstract
Heart failure is considered one of the leading causes of death worldwide. Over the years, etiological risk factors, diagnostic criteria, and classifications have been revised to create guide management needed to alleviate the global health burden caused by heart failure. Pharmacological treatments have progressed over time but are insufficient in reducing mortality. This leads to many patients developing advanced heart failure who will require surgical intervention often in the form of the gold standard, a heart transplant. However, the number of patients requiring a transplant far exceeds the number of donors. Other surgical inventions have been utilized, yet the rate of patients being diagnosed with heart failure is still increasing. Future developments in the surgical field of heart failure include the 77SyncCardia and atrial shunting but long-term clinical trials involving larger cohorts of patients have not yet taken place to view how effective these approaches can be.

Abstract
Over time, various surgical treatment strategies have evolved to manage advanced heart failure (HF). Scientific and technological breakthroughs through the last 50 years have put forward various surgical alternatives to patients with advanced HF encompassing surgical ventricular restoration to surgical gene therapy and stem cell replacement of the diseased ventricles. Organ-saving surgical options which used to be promising included dynamic cardiomyoplasty, partial resection of ventricle and cardiac wrapping with Acorn CorCap cardiac support device. These procedures were eventually abandoned due to negative outcomes and without proven disadvantages. Another organ-saving surgical option currently being considered but still make little sense is cardiac regeneration by stem cell therapy, i.e., cardiomyocyte restoration and replacement. Presently, the organ-saving surgical alternatives to treat end-stage HF are revascularization for ischemic cardiomyopathy, mitral valve surgery (repair or replacement) for ischemic mitral incompetence (IMI), left ventricular (LV) aneurysmectomy (surgical ventricular restoration) and mitral valve repair for IMI. These aforementioned procedures have become quite established approaches and with increasing experience are continuously being modified to improve outcome. Various mechanical circulatory support systems have emerged over time to improve functional status of patients with advanced HF, either as a bridge to heart transplantation or as a bridge to myocardial recovery. Likewise offered in those with contraindications to transplantation. Ventricular assist devices (VAD) can keep patients alive until an eventual transplantation. This article reviews the variety of the myriad of alternative organ-saving surgical alternatives that have been available or are currently available provided to patients with end-stage HF, their advantages and deficiencies, as well as prospects in HF therapy.
