Complete Atrioventricular Block: A Rare Complication of MitraClip Implantation.

ABSTRACT: MitraClip (Abbott Vascular, Inc., Santa Clara, California) has emerged as a viable alternative for treatment of symptomatic severe mitral regurgitation. Conduction abnormalities are not a known complication of this procedure. We report a case of complete heart block without a ventricular escape rhythm immediately following MitraClip placement near the medial leaflets (A3-P3) in a patient with underlying trifascicular block. (Level of Difficulty: Intermediate.).

Complete Heart Block: A Rare Complication of Takotsubo Syndrome.

Project description:Takotsubo syndrome was believed to be a rare acute cardiac event until recently with takotsubo cardiomyopathy being its most commonly recognized and often the diagnostic feature. Its diagnosis is becoming increasingly common with varied clinical manifestations most of whom have favorable clinical outcomes, yet it can be associated with life-threatening complications. We report a case of takotsubo syndrome leading to complete heart block which is a unique complication of an otherwise self-resolving disease.

Left ventricular reverse remodeling after transcatheter aortic valve implantation complicated by paroxysmal complete atrioventricular block.

Project description:An 86-year-old man with unremarkable clinical history complaining of asthenia and dyspnea was diagnosed with low-flow low-gradient aortic stenosis [LFLG-AS; left ventricular ejection fraction (LVEF) 40% and transaortic mean gradient 37 mmHg, increasing to 52% and 55 mmHg after dobutamine infusion]. The patient underwent transcatheter aortic valve implantation (TAVI; Edwards CENTERA™ 29, Irvine, CA, USA). The procedure and the following hospital stay were free from complications, with no changes on electrocardiography (ECG). Six months later, few syncopal episodes occurred. No signs of orthostatic hypotension or neurologic disorders were present. Echocardiography showed normal functioning of the prosthetic valve and recovery of LV systolic function (LVEF 55%). Baseline ECG and 24-h Holter monitoring were unremarkable. An implantable loop recorder (ILR) was implanted to verify the occurrence of paroxysmal conduction disturbances. One month later, during a syncopal episode, ILR interrogation showed a complete atrioventricular (AV) block. Therefore, a dual chamber, single lead pacemaker was implanted. We are providing the first report of complete AV block occurring months after TAVI, possibly because of reverse LV remodeling following TAVI, with ensuing relative oversizing of the prosthetic valve. This possibility should be considered in patients with syncope not otherwise explained, and previous TAVI, especially in cases of LFLG-AS. <Learning objective: Complete atrioventricular block can occur even months after transcatheter aortic valve implantation (TAVI), possibly because of left ventricular reverse remodeling following valve replacement, with ensuing relative valve oversizing. This possibility should be considered in patients with syncope not otherwise explained, and previous TAVI, especially in cases of low flow low gradient aortic stenosis. Loop recorder implantation should be considered in this group of patients.>.

Surgical resection and epicardial lead implantation for primary cardiac lymphoma with a complete atrioventricular block: a case report

Project description:Abstract Background Primary cardiac lymphoma (PCL) is a rare cardiac tumour with various presentations, which might cause a complete atrioventricular (AV) block, which can, in turn, cause heart failure symptoms. Case summary We report a case of a 55-year-old woman with a chief complaint of exertional dyspnoea. Her vital signs showed bradycardia, and electrocardiography revealed a complete AV block. Transthoracic echocardiography revealed a large intra-cardiac mass in the right atrium. Full-body positron emission tomography showed an elevated fluorodeoxyglucose uptake in the right atrial mass, interatrial septum, and wall of the left atrium. Since the tumour could obstruct the tricuspid valve, urgent tumour debulking surgery and epicardial lead implantation were performed. Histopathological examination results were consistent with diffuse large B-cell lymphoma. After several courses of chemotherapy, we kept her in complete remission of the tumour for 2 years. Discussion Primary cardiac lymphoma was complicated by a complete AV block and diagnosed by using the samples that we obtained in the surgery. A surgical resection of the tumour and epicardial lead implantation, combined with chemotherapy, can be an option, especially in patients who require cardiac surgery.

Transient complete heart block: a case report of a rare complication of tricuspid valve infective endocarditis.

Project description:BackgroundRight-sided tricuspid valve (TV) endocarditis can be difficult to identify and may be under-recognized in the absence of traditional risk factors. While generally identified with aortic valve pathology, infective endocarditis that extends beyond the leaflets of the TV have been reported to cause conduction disease.Case summaryWe present the case of a 63-year-old patient who presented with haemodynamically unstable complete heart block requiring temporary venous pacemaker support. Despite the absence of traditional risk factors or significant valvular disease on transthoracic echocardiogram, she was found to be persistently bacteraemic and subsequent transoesophageal echocardiogram identified large vegetation on the septal leaflet of the TV. Conduction disease was noted to reverse with antibiotic therapy and resolution of bacteraemia.DiscussionAlthough rare, right-sided endocarditis involving the triangle of Koch may present with conduction disease due to local inflammation and mechanical compression. Conduction disease associated with right-sided disease appears to be readily reversible with medical therapy and temporary device support may be appropriate in the acute setting.

Iatrogenic Arteriovenous Fistula: A Rare Complication of Pacemaker Implantation.

Project description:Severe vascular complications associated with pacemaker implantation are rare. Typically, they are overt, and require immediate resolution. We present 2 patients with insidious presentation of arteriovenous fistulae due to pacemaker implantation that were recognized early post-implantation. Both were repaired endovascularly and had good outcomes post-repair. (Level of Difficulty: Intermediate.).

Complications Following MitraClip Implantation.

Project description:Purpose of reviewTo provide a detailed overview of complications associated with MitraClip therapy and its development over time with the aim to alert physicians for early recognition of complications and to offer treatment strategies for each complication, if possible.Recent findingsThe MitraClip system (MC) is the leading transcatheter technique to treat mitral regurgitation (MR) and has been established as a safe procedure with very low adverse event rates compared to mitral surgery at intermediate to high risk or in secondary MR. Lately, the fourth MC generation has been launched with novel technical features to facilitate device handling, decrease complication rates, and allow the treatment of even complex lesions. Although the complication rate is low, adverse events are associated with increased morbidity and mortality. The most common complications are bleeding, acute kidney failure, procedure-induced mitral stenosis, and an iatrogenic atrial septal defect with unknown clinical impact.

Left Atrial Inexcitability in Children With Congenital Lupus-Induced Complete Atrioventricular Block.

Project description:Congenital atrioventricular block is a well-established immunologic complication of maternal systemic lupus erythematosus. We sought to further characterize the electrophysiological manifestations of maternal systemic lupus erythematosus on neonatal atria.Cases of isolated congenital atrioventricular block treated at our center over the past 41 years were identified. Data were extracted from clinical charts, pacemaker interrogations, ECGs, echocardiograms, and histopathological reports, when available. Of 31 patients with isolated congenital atrioventricular block, 18 were negative for maternal antibodies and had normal epicardial atrial sensing and pacing thresholds. In contrast, 12 of 13 patients with positive maternal antibodies had epicardial pacemakers, 5 (42%) of whom had left atrial (LA) inexcitability and/or atrial conduction delay. In 3 patients, the LA could not be captured despite high-output pacing. The fourth patient had acutely successful LA appendage and left ventricular lead placement. At early follow-up, an increased delay between the surface P-wave and intracardiac atrial depolarization was observed, indicative of atrial conduction delay. The fifth patient exhibited LA lead dysfunction, with atrial under-sensing and an increased capture threshold, 2 weeks after implantation. Biopsies of LA appendages performed in 2 patients showed no evidence of atrial fibrosis or loss of atrial myocytes.Herein, we report previously undescribed yet prevalent electrophysiological ramifications of maternal systemic lupus erythematosus, which extend beyond congenital atrioventricular block to encompass alterations in LA conduction, including LA inexcitability. These manifestations can complicate epicardial pacemaker implantation in newborns. In the absence of histological evidence of extensive atrial fibrosis, immune-mediated functional impairment of electrical activity is suspected.
