Periprocedural management of cardiac resynchronization therapy.

Rickard J1, Varma N.Author information 1Division of Cardiology, The Johns Hopkins Hospital, Baltimore, USA.AbstractOPINION STATEMENT: Cardiac resynchronization therapy (CRT) is an important therapy in heart failure but 30 %‒40 % of patients may not respond. Improving this rate is an important goal and requires attention to candidate selection, intraoperative procedure, and postoperative follow-up. Factors to be considered are QRS morphology, duration, and left ventricular lead position with attention to paced effects on QRS. Postprocedure follow-up is critical to correct interfering conditions (eg, anodal capture, loss of 100 % biventricular pacing because of premature ventricular complexes (PVCs) or atrial fibrillation (AF). Echocardiographic improvement following CRT, which may take up to 18 months, is a potent predictor of long-term outcomes. Correcting the status of nonresponders, when possible, is important. Remote monitoring, in conjunction with CRT optimization clinics, may facilitate multidisciplinary follow-up and enable early intervention to improve outcome.

Postoperative arrhythmia in patients with bidirectional cavopulmonary anastomosis.

Reichlin A1, Prêtre R, Dave H, Hug MI, Gass M, Balmer C.Author information 1Department of Cardiology, University Children's Hospital Zurich, Zürich, Switzerland.AbstractOBJECTIVES: Bidirectional cavopulmonary anastomosis (BDCPA) is part of the staged Fontan palliation for congenital heart defects with single-ventricle morphology. The aim of this study was to describe incidence and characteristics of early postoperative arrhythmias in patients undergoing BDCPA.

Cardiac events in Costello syndrome: One case and a review of the literature.

Hakim K, Boussaada R, Hamdi I, Msaad H.Author information Department of Pediatric Cardiology, Rabta University Hospital, Tunis.AbstractCostello syndrome is a rare syndrome associated with de novo mutations in the HRAS gene. It is mostly revealed during in the first months of life by growth retardation, facial dysmorphic features, skin and cardiac abnormalities and subsequent cognitive deficit of varying severity. We report a case of Costello syndrome in a 3-month-old infant. The initial cardiac investigations were normal except frequent premature atrial complexes. After few months, worsening arrhythmia with bursts of ventricular tachycardia were noted as well as the secondary progressive obstructive left ventricular hypertrophic cardiomyopathy (HCM). Cardiac involvement is determinant for the prognosis of Costello syndrome. It frequently consists of hypertrophic cardiomyopathy (one third of patients), with involvement of the left ventricle in half of the cases. It is often asymmetrical and associated with obstruction of the outflow recalling family hypertrophic cardiomyopathy. The natural history of HCM in Costello syndrome and its management remains poorly known because of paucity of reported cases. Progression of the HCM can be very rapid like the reported case. On the other hand, the spontaneous regression of the HCM in some patients has been reported. In addition, cardiac threatening arrhythmias may be noted. So that, cardiac assessment and monitoring with regular echocardiography and electrocardiogram follow up is mandatory.
