Congenital Heart Block.

Leonard Steinberg,

Congenital complete heart block (CCHB) defines atrioventricular conduction abnormalities diagnosed in utero or within the first 27 days of life. Maternal autoimmune disease and congenital heart defects are most commonly responsible. Recent genetic discoveries have highlighted our understanding of the underlying mechanism. Hydroxychloroquine shows promise in preventing autoimmune CCHB. Patients ... Read more >>

Novel approach to intracardiac defibrillator placement in patients with atriopulmonary Fontan: Ventricular defibrillation with an atrial positioned ICD lead.

Mathew S Padanilam, Asim S Ahmed, Brad A Clark, Joshua I Mozes, Leonard A Steinberg,

<h4>Introduction</h4>The Fontan procedure, used to palliate univentricular physiology, eliminates direct venous access to the ventricle and complicates implantable cardioverter-defibrillator (ICD) placement.<h4>Methods and results</h4>We describe two patients with Fontan palliation who underwent a novel transvenous approach to ICD placement. The approach uses a transvenous bipolar lead placed in a coronary sinus ... Read more >>

Mechanism and interpretation of two-for-one response to premature atrial complexes during atrioventricular node re-entry tachycardia.

Jasen L Gilge, Shiv Bagga, Asim S Ahmed, Brad A Clark, Parin J Patel, Eric N Prystowsky, Jeff A Olson, Leonard A Steinberg, Benzy J Padanilam,

<h4>Aims</h4>The response to premature atrial complexes (PACs) during tachycardia has been shown to differentiate atrioventricular nodal re-entrant tachycardia (AVNRT) from focal junctional tachycardia (JT). His refractory PAC (HrPACs) perturbing the next His (resetting with fusion) is diagnostic of AVNRT and such a late PAC fusing with the native beat cannot ... Read more >>

Differentiating Atrioventricular Reentry Tachycardia and Atrioventricular Node Reentry Tachycardia Using Premature His Bundle Complexes.

Benzy J Padanilam, Asim S Ahmed, Brad A Clark, Jasen L Gilge, Parin J Patel, Eric N Prystowsky, Leonard A Steinberg,

BACKGROUND:Current maneuvers for differentiation of atrioventricular node reentry tachycardia (AVNRT) and atrioventricular reentry tachycardia (AVRT) lack sensitivity and specificity for AVRT circuits located away from the site of pacing. We hypothesized that a premature His complex (PHC) will always perturb AVRT because the His bundle is obligatory to the circuit. ... Read more >>

Electrocardiographic features and prevalence of bilateral bundle-branch delay.

Leonidas Tzogias, Leonard A Steinberg, Andrew J Williams, Kent E Morris, William J Mahlow, Richard I Fogel, Jeff A Olson, Eric N Prystowsky, Benzy J Padanilam,

<h4>Background</h4>Definitive diagnosis of bilateral bundle-branch delay/block may be made when catheter-induced right bundle-branch block (RBBB) develops in patients with baseline left bundle-branch (LBB) block. We hypothesized that a RBBB pattern with absent S waves in leads I and aVL will identify bilateral bundle-branch delay/block.<h4>Methods and results</h4>Fifty patients developing transient RBBB ...

Development of rapid preexcited ventricular response to atrial fibrillation in a patient with intermittent preexcitation.

Lee W Gemma, Leonard A Steinberg, Eric N Prystowsky, Benzy J Padanilam,

Intermittent preexcitation during sinus rhythm is indicative of an accessory pathway at a very low risk for sudden death. We present the case of a 49-year-old man with intermittent preexcitation who subsequently developed rapid atrial fibrillation with a shortest preexcited R-R interval of 230 milliseconds. Electrophysiology study showed intermittent preexcitation ... Read more >>

The surface electrocardiogram predicts risk of heart block during right heart catheterization in patients with preexisting left bundle branch block: implications for the definition of complete left bundle branch block.

Benzy J Padanilam, Kent E Morris, Jeff A Olson, Janet S Rippy, Mary Norine Walsh, Natrajan Subramanian, Alex Vidal, Eric N Prystowsky, Leonard A Steinberg,

<h4>Background</h4>Patients with left bundle branch block (LBBB) undergoing right heart catheterization can develop complete heart block (CHB) or right bundle branch block (RBBB) in response to right bundle branch (RBB) trauma. We hypothesized that LBBB patients with an initial r wave (>or=1 mm) in lead V1 have intact left to ... Read more >>

Differentiating junctional tachycardia and atrioventricular node re-entry tachycardia based on response to atrial extrastimulus pacing.

Benzy J Padanilam, Joseph A Manfredi, Leonard A Steinberg, Jeff A Olson, Richard I Fogel, Eric N Prystowsky,

<h4>Objectives</h4>The purpose of this study was to differentiate non-re-entrant junctional tachycardia (JT) and typical atrioventricular node re-entry tachycardia (AVNRT).<h4>Background</h4>JT may mimic AVNRT. Ablation of JT is associated with a lower success rate and a higher incidence of heart block. Electrophysiologic differentiation of these tachycardias is often difficult.<h4>Methods</h4>We hypothesized that JT ... Read more >>

Syncope in children: diagnostic tests have a high cost and low yield.

Leonard A Steinberg, Timothy K Knilans,

<h4>Objectives</h4>To assess the use, yield, and cost-effectiveness of diagnostic tests used in the evaluation of syncope in children.<h4>Study design</h4>A retrospective review of 169 pediatric patients presenting to a tertiary care center with new onset syncope was undertaken. Test results were considered diagnostic when an abnormal result correlated with the clinical ... Read more >>
