Activation Mapping

Introduction: There is increasing evidence of the epicardial connection between the right-sided pulmonary vein (PV) carina and right atrium interrupts right-sided PV isolation after circumferential PV ablation in patients with atrial fibrillation. In such cases, carina ablation is often required. This study aimed to assess the utility of the right atrial posterior wall (RAPW) pacing in the detection of the right-sided epicardial connection (EC), evaluate the requirement for additional carina ablation after circumferential pulmonary vein (PV) ablation depending on the presence of EC, and investigate the clinical characteristics including the amount of epicardial adipose tissue (EAT) in patients with ECs. Methods and Results: Forty-one patients scheduled for PV isolation were enrolled. Before ablation, activation mapping of the LA was prospectively performed during pacing from the RAPW. EC was observed in 12 patients (EC group, 29%), whereas no EC was observed in the remaining 29 patients (non-EC group, 71%). For PV isolation, carina ablation was required in addition to circumferential ablation in 7 patients (58%) in the EC group, compared to 2 patients (7%) in the non-EC group (p < 0.003). Periatrial and intercaval EAT volumes were significantly lower (12.8 ± 6.2 vs. 23.1 ± 13.9 ml/m , p < 0.02, and 1.1 ± 0.8 vs. 2.2 ± 1.6 ml/m , p< 0.02, respectively) and the patients were younger (66.5 ± 6.6 vs. 72.4 ± 8.3 years, p < 0.03) in the EC group than in the non-EC group. Conclusions: RAPW pacing revealed EC between the RA and right PV carina in nearly a quarter of the patients.

Therapy for atrial fibrillation (AF) remains suboptimal, in large part because its mechanisms are unclear. While pulmonary vein ectopy may trigger AF, it remains uncertain how AF, once triggered, is actually sustained. Recent discoveries show that human AF is maintained by a small number of rotors or focal sources. AF sources are widely distributed in patient-specific locations, often remote from pulmonary veins and in the right atrium and stable for prolonged periods of time. In a multicentre experience, brief targeted ablation at sources (focal impulse and rotor modulation [FIRM]) terminated AF predominantly to sinus rhythm prior to pulmonary vein isolation and eliminated AF on rigorous followup. This review summarises the evidence for stable rotors and focal sources of human AF and their clinical role as ablation targets to eliminate paroxysmal, persistent and long-standing persistent AF.

Abstract Funding Acknowledgements None Introduction Partial anomalous pulmonary venous return is a rare congenital cardiac anomaly that usually involves the right pulmonary vein and an atrial septal defect. It is accounted for 0.7%. Isolated partial anomalous pulmonary venous return with an intact atrial septum is even rarer, and this condition is usually treated surgically in younger patients. We report a case of a young female, incidentally found to have a right upper pulmonary vein draining into the right atrium, confirmed by TOE and CT Venography pulmonary, with moderate right ventricular enlargement, without pulmonary hypertension, intra-cardiac shunt or accompanied congenital anomaly. A decision of surgical correction was made. We conclude that it is important to suspect PAPVC in patients with right ventricular volume overload, even in absence of ASD. Case presentation A 26-year-old female, not known to have any chronic illness. She was referred because of poor appetite and low weight, to cardiology evaluation for accidental murmur finding during examination. She had no other symptoms. The TOE was done which showed left pulmonary veins are normal, the right lower pulmonary vein is normal, and there is high suspicion of aberrant right upper pulmonary vein draining in the right atrium, no evidence of intra-cardiac shunt. CT Venography pulmonary revealed anomalous (Giant) right superior pulmonary vein to the superior vena cava and draining to the right atrium. Figure 1. Patient was referred for surgical correction. Discussion Partial anomalous pulmonary venous return is a type of left to right shunt. It is a rare congenital abnormal cardiac defect in which the pulmonary veins draining into the right atrium (RA) directly or indirectly by venous connection. Its accounted for 0.4 to 0.7%. However, as this rate is based upon autopsy data, the true prevalence of PAPVR may actually be higher. PAPVR is frequently associated with other congenital heart disease, most commonly ASD, in &gt;75% of patients. It is estimated that 10% to 15% of patients with ASD and up to 85% of patients with sinus venosus ASD have PAPVC. Exclusive of ASD, other more complex cardiac malformations occur in ∼20% of patients. PAPVR can also be an isolated defect with intact atrial septum. TOE is more sensitive than TTE in detecting PAPVR. A potential limitation of echocardiography is the availability of acoustic windows. If all four PVs are not identified emptying into the left atrium on TEE, CCT and CMR may provide complementary data . CONCLUSION In conclusion, missed diagnosis always occurs in PAPVR, the debauched and blood flow of pulmonary vein should be over-viewed carefully during TEE examination. In a patient with unexplained RV enlargement PAPVC (one or more pulmonary veins) should be considered in the differential diagnosis. Multi-modality cardiac imaging using echocardiography, CT angiography and CMR may provide a comprehensive noninvasive evaluation of PAPVC. Abstract P1729 Figure. Fig1 TOE (Top),CT (Bottom) of RUPV
