BACKGROUND: Many patients with tetralogy of Fallot (TOF) who underwent surgical correction of their congenital cardiac malformation during infancy develop right ventricular dysfunction and exercise intolerance in the long term. The right ventricle (RV) dilates due to the development of severe pulmonary regurgitation (and secondary tricuspid insufficiency). To reduce RV dilation and improve exercise tolerance pulmonary valve replacement (PVR) is the common therapeutic strategy. Whether concomitant tricuspid valve repair (TVR) is beneficial in these pure volume-overload conditions is still unknown...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a method widely used to support circulation in patients with fulminant myocarditis (FM). However, a common complication associated with ECMO is left ventricular (LV) overload. METHODS: This case series observed the effects of intra-aortic balloon pump (IABP) and beta-blockers for the treatment of LV overload after ECMO. The cases of eight patients with FM who underwent ECMO from September 2009 to July 2016 were reviewed...

Neonatal cardiogenic shock most commonly occurs due to critical congenital heart disease, sepsis, metabolic disorder or arrhythmias. In particular, enterovirus infections are common in the neonatal period, and patients can present with fulminant myocarditis. Early recognition is imperative due to its high morbidity and mortality without prompt and aggressive treatment. We present the successful treatment of fulminant neonatal enteroviral myocarditis in a pair of monochorionic diamniotic twins with cardiopulmonary support, intravenous immunoglobulin and pocapavir, an enteroviral capsid inhibitor...

OBJECTIVE: To test the hypothesis that posttraumatic stress and depressive symptoms, not cognitive or functional impairment, are associated with cardiac arrest survivors' negative recovery perceptions at hospital discharge. METHODS: Prospective observational cohort of cardiac arrest patients admitted between 9/2015-5/2017. Survival to discharge with sufficient mental status to complete a psychosocial interview was the main inclusion criterion. Perceived recovery was assessed through the question, "Do you feel that you have made a complete recovery from your arrest?" The following measures were examined as potential correlates of perceived recovery: Repeatable Battery for Assessment of Neuropsychological Status, Modified Lawton Physical Self-Maintenance Scale, Barthel Index, Modified Rankin Scale, Cerebral Performance Category, Center for Epidemiological Studies-Depression (CES-D), and PTSD Checklist-Specific (PCL-S)...

BACKGROUND: Alcoholic cardiomyopathy (ACM) is defined by a dilated and impaired left ventricle due to chronic excess alcohol consumption. It is largely unknown which factors determine cardiac toxicity on exposure to alcohol. OBJECTIVES: This study sought to evaluate the role of variation in cardiomyopathy-associated genes in the pathophysiology of ACM, and to examine the effects of alcohol intake and genotype on dilated cardiomyopathy (DCM) severity. METHODS: The authors characterized 141 ACM cases, 716 DCM cases, and 445 healthy volunteers...

OBJECTIVE: Studies of sex differences in heart rate variability (HRV) typically have not accounted for the influence of family history (FH) of cardiovascular disease (CVD). This study evaluated sex differences in HRV response to speech stress among men and women (age range 30-49 years) with and without a documented FH of CVD. METHODS: Participants were 77 adults (mean age = 39.8 ± 6.2 years; range: 30-49 years; 52% female) with positive FH (FH+, n = 32) and negative FH (FH-, n = 45) of CVD, verified with relatives of participants...

The new cardiopulmonary resuscitation (CPR) guideline emphasize the importance of chest compression, which was considered as the first step to CPR. The duration for CPR is usually limited to 30 minutes. With the development of new technology and evidence-based medicine, the success of extra longtime CPR has become possible, which is of great significance to some patients with cardiac arrest (CA), but the time limit has not been determined. On February 23rd in 2016, a 76-year-old female patient with respiratory and cardiac arrest who was on the third day after transurethral resection of bladder tumor (TUR-BT) was admitted to the intensive care unit of the General Hospital of Fushun Mining Bureau...

BACKGROUND: Higher intra-abdominal pressure may impair cardiopulmonary functions during laparoscopic surgery. While 12-15 mmHg is generally recommended as a standard pressure, the benefits of lower intra-abdominal pressure are unclear. We thus studied whether the low intra-abdominal pressure compared with the standard pressure improves cardiopulmonary dynamics during laparoscopic surgery. METHODS: Patients were randomized according to the intra-abdominal pressure and neuromuscular blocking levels during laparoscopic colorectal surgery: low pressure (8 mmHg) with deep-block (post-tetanic count 1-2), standard pressure (12 mmHg) with deep-block, and standard pressure with moderate-block (train-of-four count 1-2) groups...

Excitable cells, such as cardiac myocytes, exhibit short-term memory, i.e., the state of the cell depends on its history of excitation. Memory can originate from slow recovery of membrane ion channels or from accumulation of intracellular ion concentrations, such as calcium ion or sodium ion concentration accumulation. Here we examine the effects of memory on excitation dynamics in cardiac myocytes under two diseased conditions, early repolarization and reduced repolarization reserve, each with memory from two different sources: slow recovery of a potassium ion channel and slow accumulation of the intracellular calcium ion concentration...

The effectiveness of hyperbaric oxygen treatment for acute cardiac diseases is unknown. Similarly, the effectiveness of hyperbaric oxygen treatment for carbon monoxide intoxication is also unknown, particularly for cases in which carboxyhemoglobin (COHb) levels return to normal. Our case study revolved around a healthy twenty-year-old male patient, who suffered from carbon monoxide intoxication. The patient presented to the Emergency Department unconscious. Blood workup revealed significant carbon monoxide intoxication and cardiac injury (COHb = 41%, troponin T = 0...

Ischemic heart failure still displays the highest mortality. An early boost of intracardiac regenerative key mechanisms and angiogenetic niche signaling in cardiac mesenchymal stem cells (MSCs) could improve myocardial infarction (MI) healing. Epicardial erythropoietin (EPO, 300U kg-1 ) was compared with intraperitoneal and intramyocardial EPO treatments after acute MI in rats (n=156). Real-time PCR and confocal microscopy revealed epicardial EPO treatment enhanced intracardiac regenerative key indicators (SDF-1, CXCR-4, CD34, Bcl-2, Cyclin D1, Cdc2, MMP2), induced TGF-β/WNT signaling in intramyocardial MSC niches through direct activation of AKT, upregulations of upstream signals FOS and Fzd7 and augmented intracardiac mesenchymal proliferation 24 hours after MI...

Angiotensin II preconditioning (APC) involves an angiotensin II type 1 receptor (AT1-R)-dependent translocation of PKCε and survival kinases to the mitochondria leading to cardioprotection after ischemia-reperfusion (IR). However, the role that mitochondrial AT1-Rs and angiotensin II type 2 receptors (AT2-Rs) play in APC is unknown. We investigated whether pretreatment of Langendorff-perfused rat hearts with losartan (L, AT1-R blocker), PD 123,319 (PD, AT2-R blocker), or their combination (L + PD) affects mitochondrial AT1-R, AT2-R, PKCε, PKCδ, Akt, PKG-1, MAPKs (ERK1/2, JNK, p38), mitochondrial respiration, cardiac function, and infarct size (IS)...

Significant progress in understanding the pathophysiology of peripartum cardiomyopathy, especially hormonal and genetic mechanisms, has been made. Specific criteria should be used for diagnosis, but the disease remains a diagnosis of exclusion. Both long-term and recurrent pregnancy prognoses depend on recovery of cardiac function. Data from large registries and randomized controlled trials of evidence-based therapeutics hold promise for future improved clinical outcomes.

Open heart surgeries are common for treating ischemic and heart valve disease. During cardiac surgery, cardiopulmonary bypass (CPB) can temporarily take over the function of heart and lungs. However, elevated red blood cell (RBC) aggregation may lead to the common side-effects such as microinfarction. We investigated blood physical properties changes and the correlation between blood microstructure, viscoelastic response and biochemical changes following surgery with CPB. We examined shear-rate dependent blood viscosity, elasticity and RBC aggregate size in the pre-surgery disease state, post-surgery state and long-term recovery state of cardiac surgical patients...

Triiodothyronine (T3) and renin-angiotensin system (RAS) are functionally related in cardiovascular system. Recently, in an in vivo myocardial ischemia/reperfusion (I/R) model in rats, we showed that T3 treatment improved the post-ischemic recovery of cardiac function. In the present study, we used the same experimental model of regional I/R, obtained by 30 min occlusion of the left descending coronary artery, followed by 3-days of reperfusion, to investigate the effect of 48-h treatment (started 1 day after ischemia) with 6 µg/kg/day T3 or vehicle...

The injection of mesenchymal stem cells into the injured myocardium to induce cardiac regeneration has yielded disappointing results, conceivably because cells with cardioreparative potential must be supplied for long periods of time to produce a salutary effect. Accordingly, investigators have devised ways of directing such cells to the heart on an ongoing basis: by enhancing the action of endogenous peptides that function as cardiac homing signals (eg, stromal cell-derived factor-1). Stromal cell-derived factor-1 is released during acute cardiac injury and heart failure, but it has a short half-life because of degradation by dipeptidyl peptidase-4...

Development of durable left ventricular assist devices (LVADs), based on rotary flow blood pumps, began in earnest after the successful implantation of a catheter-mounted axial flow blood pump via intravascular access in 1988. This device, the Hemopump, successfully supported the circulation of a patient in cardiogenic shock secondary to acute rejection of a transplanted heart. Duration of support was 46 hours, resulting in complete recovery of cardiac function and hospital discharge. In effect, this sentinel event demonstrated that continuous-flow blood pumps could be used to support patients in cardiogenic shock...
