Symptoms And Signs

Pulmonary venous stenosis has been a challenge to paediatric cardiologists and surgeons. In spite of significant improvements in the management and outcome of various congenital cardiac problems, the prognosis of this condition continues to be dismal. Acquired stenosis of the pulmonary veins has been described in the adult population, especially after radiofrequency ablation for atrial arrhythmias. The outcome of this condition has generally been described to be favourable in the long term. Acquisition of pulmonary venous stenosis in childhood has a very different outcome, and is not a very well recognised entity, with symptoms and signs which are non-specific. We present 7 infants who, when first assessed, had normal pulmonary veins, but who subsequently acquired stenoses of the veins, with very significant resultant morbidity and mortality.

The Mean

Abstract Background Pulmonary vein isolation (PVI) has become the mainstay of catheter ablation of atrial fibrillation (AF). There are two commonly used methods to isolate the pulmonary veins, either point-by-point delivery of circumferential lesion sets around ipsilateral pulmonary veins using radiofrequency energy, or the application of the cryoballoon to the pulmonary vein antrum with occlusion of the vein ostium. The cryoballoon has proven to be a reliable alternative to radiofrequency ablation in acute and long-term freedom from AF. We describe our results using both modalities. Aim and Objectives to compare the safety and efficacy of cryoballoon (CB) ablation and radiofrequency (RF) ablation in treatment of paroxysmal atrial fibrillation. Patients and Methods Forty-four consecutive patients having paroxysmal AF underwent PVI using the second generation cryoballoon were compared to a retrospective cohort of 69 patients who had radiofrequency induced PVI, either by conventional RF catheter (n = 32), or a contact-force sensing-catheter (n = 37). The study took place at Ain Shams university hospitals and Royal Brompton & Harefield NHS trust. Patient data, procedural data and follow up data- at 3, 6 and 12 months- were collected and analysed. Recurrence was defined as documented AF or atrial arrhythmias with duration exceeding 30 seconds, either by 12 lead ECG or an ambulatory monitoring device. Results A total of 113 patients were studied. The mean age was 53.84 ± 15.01 for the CB group and 55.78 ± 14.84 for the RF group and females representing 40.9% vs 34.8% respectively. The mean procedural times in minutes were significantly less in the CB group (94.37 ± 39.32 vs 184.57 ± 88.19, p < 0.0001), while the median fluoroscopy times were similar [30 (11.04 - 40) vs 37.25 (14.2 - 70), p = 0.172]. Procedural complications were comparable between the two groups (p = 0.06) with 1 patient (2.3%) having long term phrenic nerve paresis. At 1 year follow up, after an initial 90-day blanking period, recurrence rate of CB was similar to RF (27.3% vs 30.4% respectively, p = 0.719), the Kaplan Meier estimates of AF- free survival for a period of 1 year were comparable between both groups (log rank test, p = 0.606). Conclusion Cryoballoon is a feasible method for pulmonary vein isolation with similar success rates to radiofrequency ablation. Cryoballoon ablation is safe with shorter duration of the procedure.

Aim. To evaluate the diagnostic utility of long-term remote monitoring of ECG compared with 24 hour Holter monitoring for the detection of cardiac arrhythmias and conduction disturbance in patients with atrial fibrillation (AF) after catheter radiofrequency ablation (RFA; isolation) of the pulmonary veins. Materials and methods. The study included 62 patients aged 58.5±11.1 years, with paroxysmal or persistent AF, after catheter RFA (pulmonary veins isolation). Patients underwent long-term remote ECG monitoring, 24 hour Holter monitoring and transthoracic echocardiogram. Results and discussion. After 24 hour Holter monitoring of 62 patients with AF after RFA in 21 of them (33.9%) was detected early recurrence of AF. Remote ECG monitoring of 18 patients, detected AF in 7 patients (39%), 2 of them were asymptomatic AF recurrence. 24 hour Holter monitoring of the same 18 patients AF recurrence was not detected at all (0%). Conclusion. Both of devices, long-term remote monitoring of ECG and 24 hour Holter monitoring detected 45.2% of recurrence of AF. Over the wearing of both devises 24 hour Holter and long-term remote monitor the last detected more events among 18 patients (33% vs 0%). Two evens of AF recurrence were asymptomatic.

AbstractCongenital pulmonary venous stenosis is a rare but important cause of pulmonary hypertension in infancy. The prognosis is uniformly poor, despite surgery and attempted balloon dilation of the narrowed veins. We performed intraoperative stenting of congenital pulmonary venous stenoses in two infants with initial clinical and hemodynamic improvement. Both patients subsequently died due to progressive pulmonary hypertension. Stenting of the pulmonary veins in this condition does not alter the natural history.
