Ventricular Tachycardia Surgery in 1992: Did the Automatic Defibrillator Change This Approach?

The role of ventricular tachycardia (VT) surgery has been changed since the automatic implantable cardioverter defibrillator (ICD) is available. We studied the follow-up of 131 patients who underwent mapping guided surgery due to recurrent VT refractory to antiarrhythmic drug treatment. There were 65 patients operated upon between 1980–1985 (group I) and 66 patients between 1986–1991 (group II). Ten patients (8%) died perioperatively (< 3 weeks after surgery) [7/65 patients, 11%, in group I and 3/66 patients, 5%, in group II (P = 0.15)]. During a mean follow-up of 41 ± 24 months, 38 of 121 patients died (31%), significantly more patients in group I (24/58 patients, 41%) than in group II (14/63 patients, 22%) (P < 0.05). In group I, there was a higher incidence of sudden (7/58 patients, 12%) or cardiac death (15/58 patients, 26%) than in group II (sudden death 4/63 patients, 6%, cardiac death 7/63 patients, 11%) (P < 0.05). There was a similar incidence of VT recurrences between group I(9/65 patients, 14%) and group II (9/66 patients, 14%). Our data show that the indication for VT surgery has changed since the ICD is available because of better patient selection.     

Sleep-related painful erections: Clinical and polysomnographic features

The aim of this study was to describe the clinical characteristics and the polysomnographic findings of a sample of patients affected by sleep-related painful erections (SRPE). In a 6-y period 18 patients were diagnosed as having SRPE. The mean age at the onset of the disease was 39.8±11.6 y and the mean duration of SRPE was 5.4±3.5 y. According to ICSD criteria, about 60% of patients had a severe form of the disease. None of the patients met any DSM IV Axis-I and Axis-II diagnoses. Twelve patients complained of excessive daytime sleepiness. SRPE patients, compared to age-matched controls, showed a reduced sleep efficiency, an increased wake after sleep onset and a reduced percentage of REM sleep. This study confirms that in SRPE there are no clear predisposing factors, no familial pattern, but REM sleep fragmentation. Concerning the pharmacological treatment, in the history of patients, propranolol and paroxetine, but not amitriptiline and lorazepam, showed a temporary efficacy in some patients.     

Second Degree SA Block and Escape-Capture Bigeminy Diagnosed by Esophageal Electrocardiography

We report a case of escape-capture bigeminy, a rare form of arrhythmia, occurring after treatment of wide-QRS tachycardia and diagnosed by esophageal electrocardiography recording of atrial activity which was not evident on the surface electrocardiogram.     

Total Arterial Revascularization of the Heart using both Mammary Arteries and the Right Gastroepiploic Artery

From April 1988 to April 1989, nine patients (seven men and two women) with coronary three-vessel disease and disabling angina underwent elective myocardial revascularization. None of the patients had available veins because of previous bypass procedures (three) or extensive varicosis (six). On standard cardiopulmonary bypass and cardioplegic arrest the right and the left mammary arteries (RIMA, LIMA) and the right gastroepiploic artery (RGEA) were anastomosed each to a major coronary branch (none of them as free graft) in each patient. All patients survived the operation but one, who died 2 weeks after the operation of a bilateral pneumonia. Autopsy revealed patent anastomoses. One patient had to be reexplored for bleeding. Two patients required temporary inotropic support. There was no perioperative myocardial infarction. All survivors were discharged home in an average of 18.7 days after the operation, are free from angina, and all have negative stress tests (mean follow-up 7.7 months) but one with severe coronary atherosclerosis who experiences slight exertional angina despite good patency of the grafts. Five patients were recatheterized after a mean interval of 5.4 months after operation revealing in all cases patent anastomoses. Total revascularization of the heart with arterial grafts is feasible, safe, and it could become the method of choice if patency persists in the long run.
