Toll-like receptor 4 mediates maladaptive left ventricular remodeling and impairs cardiac function after myocardial infarction.
Timmers L, Sluijter JP, van Keulen JK, Hoefer IE, Nederhoff MG, Goumans MJ, Doevendans PA, van Echteld CJ, Joles JA, Quax PH, Piek JJ, Pasterkamp G, de Kleijn DP
Left ventricular (LV) remodeling leads to congestive heart failure and is a main determinant of morbidity and mortality following myocardial infarction. Therapeutic options to prevent LV remodeling are limited, which necessitates the exploration of alternative therapeutic targets. Toll-like receptors (TLRs) serve as pattern recognition receptors within the innate immune system. Activation of TLR4 results in an inflammatory response and is involved in extracellular matrix degradation, both key pr...

Iatrogenic perforation of the posterior mitral valve leaflet: a rare complication of pacemaker lead placement.
Konings TC, Koolbergen DR, Bouma BJ, Groenink M, Mulder BJ
An inadvertently placed pacing lead in the left ventricle (LV) is a rare and often underdiagnosed complication of pacemaker implantation. We present a case of a 73-year-old woman who was evaluated for dyspnea, 10 years after transvenous pacemaker implantation. Transthoracic and transesophageal echocardiography revealed a secundum atrial septal defect through which the ventricular pacing lead was placed into the LV. Whereas percutaneous extraction of the lead seemed too full of risk, the patient...

Glycemic control, lipid-lowering treatment, and prognosis in diabetic patients with peripheral atherosclerotic disease.
Feringa HH, Karagiannis SE, Vidakovic R, Elhendy A, Schouten O, Boersma E, Bax JJ, Poldermans D
Glycemic control may be an underestimated risk factor in diabetic patients with peripheral arterial disease (PAD). Chronic statin therapy may improve glycemic control and outcome in these patients. In an observational cohort study of 425 consecutive diabetic patients with PAD, chronic statin therapy was noted, the ankle-brachial index was measured, and serial glycemic hemoglobin (HbA(1c)) measurements were obtained. During follow-up (median 7 years), all-cause mortality and cardiac death occurre...

Reduction of myocardial infarct size by human mesenchymal stem cell conditioned medium.
Timmers L, Lim SK, Arslan F, Armstrong JS, Hoefer IE, Doevendans PA, Piek JJ, El Oakley RM, Choo A, Lee CN, Pasterkamp G, de Kleijn DP
Although paracrine effects of mesenchymal stem cells (MSCs) have been suggested previously, cardioprotection by human MSC secretions has never been demonstrated. Human MSC-conditioned medium (CM) was collected by following a clinically compliant protocol. In a porcine model of ischemia and reperfusion injury, intravenous and intracoronary MSC-CM treatment significantly reduced myocardial nuclear oxidative stress as determined by immunostaining for 8-hydroxy-2'-deoxyguanosine. In addition, e...

Multi-modality imaging to assess left atrial size, anatomy and function.
Tops LF, van der Wall EE, Schalij MJ, Bax JJ
The left atrium (LA) anterior-posterior diameter was one of the first standardised echocardiographic parameters. However, the clinical importance of LA size assessment has been neglected for some time. Recent population-based studies have demonstrated the prognostic value of LA size for long-term outcome. Furthermore, with new dedicated techniques such as tissue Doppler imaging, it has become feasible to assess (regional) LA function. In addition, the introduction of catheter ablation procedures...

Optimal use of echocardiography in cardiac resynchronisation therapy.
Bleeker GB, Yu CM, Nihoyannopoulos P, de Sutter J, Van de Veire N, Holman ER, Schalij MJ, van der Wall EE, Bax JJ
Echocardiography has several roles in patients with cardiac resynchronisation therapy (CRT). First, it can optimise selection of CRT candidates by demonstration of left ventricular (LV) dyssynchrony. Second, it can be used to assess immediate response to CRT, including detection of acute LV resynchronisation. Echocardiography is also useful to evaluate long-term benefit from CRT. Finally, echocardiography is important in optimisation of pacemaker settings, including AV and VV optimisation.

Catheter ablation of ventricular tachycardia after repair of congenital heart disease: electroanatomic identification of the critical right ventricular isthmus.
Zeppenfeld K, Schalij MJ, Bartelings MM, Tedrow UB, Koplan BA, Soejima K, Stevenson WG
Background: Catheter ablation of ventricular tachycardia (VT) after repair of congenital heart disease can be difficult because of nonmappable VTs and complex anatomy. Insights into the relation between anatomic isthmuses identified by delineating unexcitable tissue using substrate mapping techniques and critical reentry circuit isthmuses might facilitate ablation. Methods and results: Sinus rhythm voltage mapping of the right ventricle was performed in 11 patients with sustained VT after repair...

Activation of signaling molecules and matrix metalloproteinases in right ventricular myocardium of rats with pulmonary hypertension.
Umar S, Hessel M, Steendijk P, Bax W, Schutte C, Schalij M, van der Wall E, Atsma D, van der Laarse A
Pulmonary hypertension induces right ventricular (RV) overload, which is transmitted to cardiomyocytes via integrins that activate intracellular messengers, including focal adhesion kinase (FAK) and neuronal nitric oxide synthase (NOS1). We investigated whether RV hypertrophy (RVH) and RV failure (RVF) were associated with activation of FAK, NOS1, and matrix metalloproteinases (MMPs). Rats were treated without (RVC) or with a low dose of monocrotaline (30mg/kg) to induce RVH, and with a high dos...
