Y Cao, P-Y Zhang
Hypertrophic cardiomyopathy (HCM) is a complex but common monogenic cardiovascular disorder characterized by unexplained non dilated left ventricular (LV) thickening in the absence of another cardiac or systemic disease. The condition is associated with sudden and unexpected death in young individuals including trained athletes. HCM represents a genetic disorder caused by mutations in genes encoding sarcomeric proteins of the cardiac myocyte. This review article discusses the genetics behind HCM, its clinical presentation, and diagnosis and the present-day pharmacological management of HCM...

Hamartoma of mature cardiac myocytes (HMCM) is a rare benign pseudoneoplastic myocardial lesion. We describe a case of 39-year-old Bulgarian woman living in the Czech Republic, who died because of rupture of anterior communicating artery aneurysm, and severe bronchopneumonia. An incidental finding at the autopsy was a whitish unencapsulated and not sharply demarcated tumor of the left ventricle and adjacent area of interventricular septum, which protruded above the plane of section. Microscopically the tumor consisted of various different forms of disorganized hypertrophic mature cardiac myocytes without vacuolization of cytoplasm, focally in a "herringbone" pattern...

Coronary artery perforation (CAP) is a rare, but potentially mortal possible complication of percutaneous coronary intervention. There are several treatment options for this complication, including prolonged balloon dilatation, use of a coronary stent graft, and bypass surgery. In this case report, a 65-year-old female patient who was admitted to the catheter laboratory with a diagnosis of acute coronary syndrome, was presented. Coronary angiography revealed total occlusion in the mid segment of the right coronary artery and a drug-eluting stent was implanted under 12 atm of pressure following pre-dilatation with a perfusion balloon...

The thoracic duct, a terminal lymph vessel, is thought to dilate after the intake of a fatty meal. However, this physiological change has not been well explored in vivo. Therefore, the present study aimed to assess serial changes in the thoracic duct after the intake of a fatty meal using magnetic resonance thoracic ductography (MRTD). Eight healthy volunteers were subjected to one MRTD scan before a fatty meal and eight serial MRTD scans every hour thereafter. The cross-sectional areas of the thoracic duct were estimated using MRTD measurements of the diameters of the thoracic duct at the upper edge of the aortic arch, the tracheal bifurcation, the mid-point between the tracheal bifurcation and the left part of the diaphragm and the left part of the diaphragm...

Arterial aneurysms (AA) can be classified as true aneurysms, characterized by the persistence of all three layers of the arterial wall with progressive dilation and wall thinning; arterial pseudoaneurysms (APAs) are characterized by a tear in the vessel wall and a periarterial hematoma formation. They could occur due to a visceral, retroperitoneal, or peripheral origin. Most AA/APA are usually found incidentally, and it is imperative to be vigilant in order to diagnose and manage them due to their potentially life-threatening complications...

BACKGROUND: Anastomotic stricture is a common complication following esophageal atresia (EA) repair. Patients with a recalcitrant stricture may require surgical intervention. The technique of re-anastomosis after stricture resection can affect patient outcomes. STUDY DESIGN: EA patients who underwent anastomotic stricture resection from July 2010 to February 2017 were reviewed. Patients after stricture resection in which slide esophagoplasty was performed were compared to the conventional approach of end-to-end anastomosis...

BACKGROUND: Induction of labor occurs in more than 20% of pregnancies, which equates to approximately 1 million women undergoing an induction in the United States annually. Regardless of how common inductions are, our ability to predict induction success is limited. Although multiple risk factors for a failed induction have been identified, risk factors alone are not enough to quantify an actual risk of cesarean for an individual woman undergoing a cesarean. OBJECTIVE: The objective of this study was to derive and validate a prediction model for cesarean after induction with an unfavorable cervix and to create a web-based calculator to assist in patient counseling...

AIM: Gather "proof-of-concept" evidence of the adverse developmental potential of cotinine (a seemingly benign biomarker of recent nicotine / tobacco smoke exposure). METHODS: Pregnant C57 mice drank nicotine or cotinine-laced water for 6wks from conception (NPRE = 2% saccharin+100μg nicotine/ml; CPRE = 2% saccharin + 10μg cotinine/ml) or 3wks after birth (CPOST = 2% saccharin + 30μg cotinine/ml). Controls drank 2% saccharin (CTRL). At 17±1weeks (male pups; CTRL n=6; CPOST n=6; CPRE n=8; NPRE n=9) we assessed (i) cardiovascular control during sleep; (ii) arterial reactivity ex vivo; (iii) expression of genes involved in arterial constriction / dilation...

Because of its own unfavourable evolution, HIV infection was until recently considered a contraindication for organ transplantation. The introduction of highly active antiretroviral therapy prolonged the life expectancy of these patients and allowed the manifestation of disorders directly or indirectly related to HIV infection, mainly liver, kidney and cardiovascular diseases. We present a case of cardiac transplantation due to dilated cardiomyopathy that was performed in a patient with a recently detected HIV infection...
