Radiofrequency ablation of ventricular premature contraction originating from a native coronary cusp after transcatheter aortic valve replacement

We describe a case of radiofrequency ablation of ventricular premature contraction (VPC) originating from the left ventricular outflow tract after transcatheter aortic valve replacement. The VPC origin was the native aortic valve annulus between the left and right coronary cusps. Radiofrequency ablation was successfully performed by manipulating the ablation catheter from the gap between the sinotubular junction and implanted valve.

Background/Aim: Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities play an undoubted role. Aim of the study was to evaluate the increase of premature ventricular contractions (PVC) and complex ventricular arrhythmias during mental stress in elderly patients candidate to the transcatheter aortic valve replacement (TAVR). Methods: In eighty-one elderly patients with AS we calculated several short-period RR- and QT-derived ...

We report a patient of undiagnosed Ebstein’s anomaly who was apparently asymptomatic but presented with the acute coronary syndrome. This case report deals with a rare combination of cong enital heart disease (Ebstein’s anomaly) and coronary artery disease. Ebstein’s anomaly (EA) has a prevalence of 1% of all congenital heart diseases, and little evidence is reported in the literature where EA along with coronary artery disease (CAD) exists in individuals less than 45 years old. Therefore, this case report brings attention to the rarity of those pathologies, which individually are already considered ...

Publication date: Available online 16 July 2019Source: Canadian Journal of CardiologyAuthor(s): Paul KhairyAbstractThe expanding population of adults with congenital heart disease (CHD) combined with the pervasiveness of arrhythmias has resulted in the rapid growth of a dedicated sector of cardiology at the intersection between two subspecialties: electrophysiology and adult CHD. Herein, practical considerations are offered regarding urgent referral for catheter ablation of atrial arrhythmias, anticoagulation, and primary prevention implantable cardioverter-defibrillators (ICDs). Patients with Ebstein anomaly and ventricul...

Cardiac arrhythmias are common after cardiac surgery and have profound sequelae. Bradycardias are typically transient and have reversible causes; however, persistent atrioventricular block is an indicator for permanent pacemaker implantation after valvular surgery. Transcatheter aortic valve surgery is associated with even higher rates of permanent pacemaker implantation. Atrial fibrillation, the most common postoperative arrhythmia, is associated with ischemic stroke, myocardial infarction, congestive heart failure, and short-term mortality. Ventricular arrhythmias have extremely high in-hospital mortality, as well as lon...

This study was designed to observe the association between glycemic control and outcome of patients after open heart surgery in adult population. Materials and Methods: Data was collected retrospectively in all patients who underwent open cardiac surgery (coronary artery bypass grafting, valve, or bypass grafting with valve surgery) and survived 72 hours postoperatively and had diabetes. The study was conducted from January 2015 to December 2016. Results: Of the 129 patients included in the study, male dominated 101 (78.3%). Most frequent surgery was coronary artery bypass grafting (CABG) 123 (95.3%), CABG plus a...

AbstractBackgroundReadmissions after cardiac surgery are common and associated with increased morbidity, mortality and cost of care. Policymakers have targeted coronary artery bypass grafting to achieve value ‐oriented health care milestones. We explored the causes of readmission following cardiac surgery among a regional consortium of hospitals.MethodsUsing administrative data, we identified patients readmitted to the same institution within 30 days of cardiac surgery. We performed standardized review of readmitted patients ’ medical records to identify primary and secondary causes of readmission. We evaluated cau...

When atrial fibrillation (AF) occurs after cardiac surgery, surgeons consider the arrhythmia a nuisance rather than a complication. This reflects natural optimism. Although perioperative AF is most often self-limited, it is associated with increased risk of stroke and death, increased hospital length of stay, and increased health care costs.1 Still, we tend not to worry too much because postoperative AF tends to resolve regardless of treatment strategy.1

Surgical ventricular restoration (SVR) has been introduced as therapeutic strategy for adverse postinfarction left ventricle (LV) remodeling.1 Little information is available regarding SVR in pediatric patients who are rarely affected by coronary artery disease and its related complications.

Conclusions: Trans-apical off-pump MV repair with the NeoChord system is a safe, minimally invasive procedure, with few minor complications. In well-selected candidates it provides successful treatment of degenerative MR. Results are anatomy dependent, so preoperative patient selection is crucial. PMID: 31119000 [PubMed]
