Complicated pathophysiological syndrome associated with irregular functioning of the heart leading to insufficient blood supply to the organs is linked to congestive heart failure (CHF) which is the leading cause of death in developed countries. Numerous factors can add to heart failure (HF) pathogenesis, including myocardial infarction (MI), genetic factors, coronary artery disease (CAD), ischemia or hypertension. Presently, most of the therapies against CHF cause modest symptom relief but incapable of giving significant recovery for long-term survival outcomes...

Organogenesis depends on orchestrated interactions between individual cells and morphogenetically relevant cues at the tissue level. This is true for the heart, whose function critically relies on well-ordered communication between neighboring cells, which is established and fine-tuned during embryonic development. For an integrated understanding of the development of structure and function, we need to move from isolated snap-shot observations of either microscopic or macroscopic parameters to simultaneous and, ideally continuous, cell-to-organ scale imaging...

BACKGROUND: Balloon aortic valvuloplasty (BAV) is often utilized as a bridge prior to surgical or transcatheter aortic valve replacement. Chronic kidney disease (CKD) is commonly present in patients with aortic stenosis, however, its association with outcomes following BAV has not been well studied. Accordingly, we sought to assess the impact of CKD on mortality in adults undergoing BAV. METHODS: The Nationwide Inpatient Sample was screened for hospitalizations involving adults undergoing BAV from 2006 to 2012...

BACKGROUND: Cancer patients with recently placed drug-eluting stents (DESs) often require premature dual antiplatelet therapy (DAPT) discontinuation for cancer-related procedures. Optical coherence tomography (OCT) can identify risk factors for stent thrombosis such as stent malapposition, incomplete strut coverage and in-stent restenosis and may help guide discontinuation of DAPT. METHODS: We conducted a single-center prospective study in cancer patients with recently placed (1-12 months) DES who required premature DAPT discontinuation...

Post-infarction ventricular septal defect (VSD) is a rare but potentially lethal complication of acute myocardial infarction. Medical management is usually futile, so definitive surgery remains the treatment of choice but the risk surgery is very high and the optimal timing for surgery is still under debate. A 55-year-old man with no previous medical history attended the emergency-room for 12 h evolution of oppressive chest pain and strong anginal pain 7 days ago. On physical examination, blood pressure was 96/70 mmHg, pansystolic murmur over left sternal border without pulmonary crackles...

Ventricular assist devices are used in children with heart failure as a bridge to myocardial recovery or cardiac transplantation. Anthracyclines cause cardiac toxicity and may result in acute or long-term cardiac failure. We describe the use of a ventricular assist device as a bridge to recovery in a child with severe acute anthracycline-induced cardiomyopathy, and we review the associated literature. A 6-year-old girl was treated for acute myeloblastic leukaemia with daunorubicin and mitoxantrone. After 2 weeks her final dose of chemotherapy, her Left Ventricular Ejection Fraction decreased to 21%...

BACKGROUND: Plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentration is increased in dogs with myocardial dysfunction, and cell-free DNA (cfDNA) increases in numerous disease states. In humans, both of these biomarkers can be altered after endurance exercise. OBJECTIVE: To investigate the effect of prolonged strenuous exercise on circulating NT-proBNP and cfDNA concentrations in working farm dogs. ANIMALS: Six healthy, privately owned working farm dogs (4 Huntaways and 2 heading dogs) from the same hill country farm in New Zealand...

Myocardial bridging (MB) is considered as a topic of high interest since its occurrence in different studies is statistically significant, and the clinical manifestations of this phenomenon are complicated with cardiovascular diseases. Whether the MB participates in heart diseases and has a decisive effect to life-threatening situations is still under research, and many studies have been conducted to clarify the abovementioned question. A case report with a MB on the left anterior descending coronary artery is presented in the current study, and a review of the literature is provided as well...

Through concerted endeavours in the fields of surgery, medicine, and biomedical engineering, patronized by government and industry, ventricular assist devices have become an established surgical treatment to support the failing heart, which could easily and simply surpass the frequency of heart transplantation. Be it as it may, complications and adverse events have unfolded, and these facilitated the way to newer biomedically-engineered pump designs in search of the perfect support for a failing heart. Areas covered: This review focuses on the evolution of the continous-flow ventricular assist device as an accepted mode of treatment in advanced heart failure, as a bridge to myocardial recovery, as a bridge to heart transplantation and as a permanent therapy, with its attendant complications and long-term outcome...

Extensive perinatal myocardial infarction caused by coronary artery thrombosis is extremely rare and has a dismal prognosis. We report a 3.5-kg neonate who presented at birth with an extensive myocardial infarction caused by aortic root and left main coronary artery thrombus after an emergency cesarean section. We performed emergency surgical thrombectomy and insertion of extracorporeal membrane oxygenation support. After subsequent conversion to long-term left ventricular assist device with an EXCOR device (Berlin Heart, Berlin, Germany), the patient had no ventricular recovery after 163 days of support...

The course of epicardial coronary arteries into a muscular tunnel under a bridge of myocardium is known as myocardial bridging (MB). This could be a benign anomaly, nevertheless, it could have a great impact on the quality of life in the setting of severe anginal symptoms. The clinical presentation and diagnosis could be challenging in those patients. The treatment options start from simple medical therapy to surgical intervention in refractory cases, the role of percutaneous coronary intervention (PCI) is limited in MB...

Acute coronary disease is a rare entity in young people and is mostly related to atherosclerotic disease. However, other causes such as myocardial bridges, coronary artery dissection and antiphospholipid syndrome may be present. The prognosis of the disease in this group of patients is favorable; although women may have a higher morbidity because diagnosis and treatment can be delayed. The goal of this review is to update the knowledge about risk factors and prognosis of young patients with an acute coronary event compared to the older population...
