Anesthetic management for transurethral resection of the bladder in a 74-year-old man with uncorrected tetralogy of Fallot.

We report a case of general anesthesia for transurethral resection of the bladder in a 74-year-old male patient with uncorrected tetralogy of Fallot. This case illustrates the pertinent pathophysiology of the complex cardiac lesion related to tetralogy of Fallot as well as the feasibility and issues with regard to the anesthetic management.

Effect of atrial septal mobility on transcatheter closure of interatrial communications.

BACKGROUND: Transcatheter techniques have evolved as alternatives to surgical closure of interatrial communications due to its less invasive nature and low morbidity. The technique may be limited by the inability to deploy the device and, thus, may be complicated by significant residual shunting. Mobile or redundant septal tissue has been implicated as a possible cause of unsuccessful closure. METHODS: To determine if atrial septal hypermobility precludes successful transcatheter device closure of interatrial communications, 69 patients (mean age 46.4 +/- 17.5 years [male:female ratio 34:35]) with periprocedural transesophageal echocardiograms were reviewed. Septal excursion was defined as the maximal transit of the interatrial septum between either side of the plane connecting the superior and inferior attachment points. Unsuccessful closure was defined as subsequent cardiac surgery to close the defect, inability to deploy the device, recurrent attempts at closure, device malalignment, residual shunting greater than mild in degree on follow-up transthoracic study, and procedural complications. RESULTS: Reasons for closure were the following: embolic events (n = 48); platypnea/orthodeoxia (n = 15); atrial septal defect with right ventricular dilatation and paroxysmal atrial tachycardia (n = 2); atrial septal defect (n = 3); and prophylactic patent foramen ovale closure in a scuba diver (n = 1). Successful closure occurred in 76% of patients (n = 53). Compared with those patients with successful transcatheter closure, the mean septal excursion in patients with failed closure was 0.66 +/- 0.56 cm versus 0.76 +/- 0.47 cm (P = not significant [NS]). CONCLUSION: Our results do not support the concern that exaggerated septal mobility compromises successful device closure of interatrial communications.

Percutaneous transcatheter closure of patent foramen ovale in patients with paradoxical embolism.

BACKGROUND: Percutaneous transcatheter closure of patent foramen ovale (PFO) is used as an alternative to surgery or long-term anticoagulation for the treatment of patients with paradoxical embolism and PFO. METHODS AND RESULTS: We report the immediate and long-term clinical and echocardiographic outcome of 110 consecutive patients (58 males, mean age 47+/-14 years) who underwent transcatheter closure of PFO because of paradoxical embolism between 1995 and 2001. Procedural success, defined as successful deployment of the device and effective occlusion (no, or trivial, shunt after device placement), was achieved in all (100%) patients. There was no in-hospital mortality, 1 device migration requiring surgical intervention (0.9%), and 1 episode of cardiac tamponade (0.9%) requiring pericardiocentesis. A progressive increment in full occlusion was observed (44%, 51%, 66%, and 71% at 1 day, 6 months, and 1 and 2 years, respectively, after device placement). At a mean follow-up of 2.3 years, 2 patients experienced recurrent neurological events (1 fatal stroke and 1 transient ischemic attack), representing an annual risk of recurrence of 0.9%. In addition, 4 (3.6%) of the patients required reintervention for device malalignment or significant shunt. Kaplan-Meier analysis showed a freedom from recurrent embolic events and reintervention of 96% and 90% at 1 and 5 years, respectively. CONCLUSIONS: Transcatheter closure of PFO is a safe and effective therapy for patients with paradoxical embolism and PFO. It is associated with a high success rate, low incidence of hospital complications, and low frequency of recurrent systemic embolic events.
