INTRODUCTION: Mental stress-induced ischemia approximately doubles the risk of cardiac events in patients with coronary artery disease, yet the mechanisms underlying changes in coronary blood flow in response to mental stress are poorly characterized. Neuronal nitric oxide synthase (nNOS) regulates basal coronary blood flow in healthy humans and mediates mental stress-induced vasodilation in the forearm. However, its possible role in mental-stress-induced increases in coronary blood flow is unknown...

Air embolism is an uncommon, but potentially life-threatening event for which prompt diagnosis and management can result in significantly improved patient outcomes. Most air emboli are iatrogenic. Arterial air emboli may occur as a complication from lung biopsy, arterial catheterization or cardiopulmonary bypass. Immediate management includes placing the patient on high-flow oxygen and in the right lateral decubitus position. Venous air emboli may occur during pressurized venous infusions, or catheter manipulation...

Quadrigeminal arachnoid cysts (QAC) are usually accompanied by a symptomatic obstructive hydrocephalus. Several endoscopic and surgical treatments exist; however, the critical location of these cysts further complicates treatment and usually more than one procedure is required. In this report, a 31 year old female with QAC and associated obstructive hydrocephalus was successfully treated with stereotactic placement of a permanent ventricular - cystic stent (intraventricualr - cystic catheterization) in single - session...

Instantaneous wave-free ratio (iFR) is a vasodilator-free index and is reported to have a good correlation with fractional flow reserve (FFR). Hemodialysis patients exhibit left ventricular hypertrophy, reduced arterial compliance, and impaired microcirculation. Such a coronary flow condition in these patients may influence the relationship between iFR and FFR. This study assessed the impact of hemodialysis on the relationship between iFR and FFR. The study enrolled 196 patients with 265 stenoses who underwent assessment via iFR, FFR assessment, and right heart catheterization...

Primary hyperparathyroidism (pHPT) causes hypercalcemia. The treatment for pHPT is surgical dissection of the hyperfunctioning parathyroid gland. Lower rates of hypocalcemia and recurrent laryngeal nerve injury imply that minimally invasive parathyroidectomy (MIP) is safer than bilateral neck resection. Current trends in MIP use can be inferred only by reference to preoperative localization studies. Noninvasive imaging studies (typically preoperative localization studies) show good detection rates of hyperfunctioning glands; however, there have also been cases of nonlocalization or discordant results...

The aim of the study was to evaluate the safety, feasibility, and economic benefit of a high-volume operator performing common interventional procedures in a rural region of the United States (U.S.). Rural areas of the U.S., even with well-equipped cardiac catheterization laboratories, may not have a full-time pediatric interventional cardiologist (PIC); this requires patients to travel out of state even for simple interventions. Since 2005, we have adopted a policy of performing cardiac catheterizations and common interventional procedures with a visiting PIC...

Context:Broken heart syndrome or Takotsubo cardiomyopathy (TC) is a disorder characterized by transient left ventricular apical ballooning that almost invariably precedes emotional or physical stress. Although the patients with chronic kidney disease on hemodialysis have shown to exhibit sustained activity of sympathetic nervous system, the presentation of TC in these patients is a rare entity with few case reports in the literature. Case Report: A 75-year-old female with past medical history of end-stage renal disease presented with chest pressure and heaviness that started during her maintenance hemodialysis session...

BACKGROUND: Chest pain is a common presenting symptom in the emergency department (ED). Although the diagnostic workup for chest pain is well established, the best time to perform invasive cardiac catheterization in patients with low to moderate risk of coronary artery disease is still unclear, particularly if noninvasive tests such as the electrocardiogram (ECG) and nuclear myocardial perfusion scan show nonsignificant findings. CASE REPORT: We present the case of a 52-year-old female who presented to the ED with acute-onset chest pain that had started early in the morning while she was sleeping...
