Pharmacologic challenge with sodium channel blockers is part of the diagnostic workout in patients with suspected Brugada syndrome. The test is overall considered safe but both ajmaline and flecainide detain well known pro-arrhythmic properties. Moreover, the treatment of patients with life-threatening arrhythmias during these diagnostic procedures is not well defined. Current consensus guidelines suggest to adopt cautious protocols interrupting the sodium channel blockers as soon as any ECG alteration appears...

Waldenström's macroglobulinemia (WM) manifests as hyperviscosity syndrome. Cryoglobulinemia, which may increase blood viscosity or induce thrombosis in association with decreased body temperature, can occur in combination with WM. We describe the management of an 82-year-old woman with WM, hyperviscosity syndrome, and cryoglobulinemia who required open aortic valve replacement. Decreased body temperature in this patient was prevented during cardiopulmonary bypass by using a forced air warming system and normothermic cardioplegia with continuous warm blood cardioplegia perfusion...

BACKGROUND: Atrial fibrillation (AF) is the most frequent complication of surgery performed on cardiopulmonary bypass (CPB) and recent work associates CPB with postoperative inflammation. We have shown that all tissue injury releases mitochondrial damage associated molecular patterns (mtDAMPs) including mitochondrial DNA (mtDNA). This can act as a direct, early activator of neutrophils (PMN), eliciting a systemic inflammatory response syndrome (SIRS) while suppressing PMN function. Neutrophil Extracellular Traps (NETs) are crucial to host defence...

BACKGROUND: In cardiac surgery, elevation of procalcitonin (PCT) could be observed postoperatively in the absence of any evidence of infection and also seems to be a prognostic marker. PCT levels measured in patients undergoing Type A aortic dissection (TAAD) were used to determine prognostic values for complications and surgical outcomes. METHODS: Measurements of PCT, C-reactive protein (CRP), and leukocyte count were observed in TAAD surgery patients (n = 251; average age: 49...

Postoperative vasoplegic syndrome (VS) is characterized by low systemic vascular resistance, normal or elevated cardiac output, and poor response to volume expansion. The incidence of VS after cardiac surgery requiring cardiopulmonary bypass is about 20%. Sometimes, VS becomes refractory and initial treatments do not work, rendering treatment a great challenge. In this study, we describe a young male patient with endocarditis undergoing tricuspid valve replacement. When being weaned off cardiopulmonary bypass, the patient experienced VS...

REVIEW
T Graf, H Thiele
In recent years, the widespread use of partial mechanical cardiac support and even temporary complete replacement of cardiac function has been established in many intensive care units in the treatment of refractory cardiogenic shock. There is a difference between partial left-ventricular assist devices (LVAD) and the possibility of complete heart (and lung) replacement by extra corporeal life support (ECLS). Despite the use of mechanical support devices, the mortality of cardiogenic shock remains high. The consideration of using percutaneous LVAD and ECLS in cardiogenic shock should be considered in refractory cardiogenic shock patients in addition to support by catecholamines and after early revascularization in acute coronary syndromes...

Ivemark syndrome is a heterotaxy syndrome which affects multiple organs and affects roughly 1 in every 6000 deliveries. Specifically, it can cause total anomalous pulmonary venous return and cardiac defects, which ultimately lead to decreased life expectancy. In order to better understand the nature of cardiac structures, CT angiogram has been heavily relied upon as it also allows for 3D reconstruction and optimal visualization of those features. This specific case presents with an anomalous venous return accompanied by multi-organ right isomerism that was reconstructed with 3D CT angiogram to better visualize and understand the cardiopulmonary system, as well as contribute to a fund of knowledge in hopes of discovering a solution to this condition...

Venoarterial extracorporeal membrane oxygenation (ECMO) can provide temporary cardiopulmonary support for patients in hemodynamic extremis or refractory heart failure until more durable therapies-such as cardiac transplantation or a left ventricular assist device-can be safely implemented. Conventional ECMO cannulation strategies commonly employ the femoral artery and vein, constraining the patients to the supine position for the duration of ECMO support. We have recently adopted a modified cannulation approach to promote patient mobility, rehabilitation, and faster recovery and to mitigate complications associated with femoral arterial cannulation, such as limb ischemia and compartment syndrome...

Intracaval buffle repair of scimitar syndrome is classically performed under deep hypothermic circulatory arrest or using low-flow modalities of cardiopulmonary bypass with peripheral cannulation. We propose an alternative perfusion approach to the procedure using total intrapericardial cannulation under full-flow normothermic cardiopulmonary bypass.

BACKGROUND: Takostsubo (stress) cardiomyopathy (TC) is a clinical syndrome featuring transient left ventricular dysfunction and wall-motion abnormalities, usually following emotional or physical stress. The diagnosis of TC depends on fulfillment of multiple clinical criteria. Although the pathogenesis has not been firmly established, myocardial cathecholamine toxicity is thought to represent a primary mechanism. The vast majority of patients with TC survive. However, a rare cause of death in TC is myocardial rupture...
