AS-129Early Complications of Low-Dose, Echo-Guided Alcohol SeptalAblation. Josef Veselka, David Zemanek, Pavol Tomasov,Stanislava Homolova. University Hospital Motol, Prague, CzechRepublic.

Background: Alcohol septal ablation (ASA) is a catheter-based inter-vention that has been used as an alternative to surgical myectomy inhighly symptomatic patients with hypertrophic obstructive cardiomy-opathy (HOCM).

Methods: This retrospective study was designed to evaluate theincidence of major complications in the midterm follow-up of low-dose(1.0–2.5 mL of ethanol), echo-guided alcohol septal ablation.

Results: Enrolled in the study were 101 consecutive patients (56 �15 years) with highly symptomatic HOCM. At 6 months, there was asignificant decrease in resting outflow gradient accompanied by reduc-tion in basal septal diameter and improvement in symptoms (p �0.01).Two patients (2%) experienced procedural ventricular tachycardiasterminated by electrical cardioversion. Eighty-seven patients (86%)underwent an uneventful postprocedural hospital stay. The postproce-dural complete heart block occurred in 10 patients (10%), and subse-quent permanent pacemaker was implanted in 4 cases (4%). Sustainedventricular arrhythmias requiring electrical cardioversion occurred in 4patients (4%) within postprocedural hospital stay. Subsequently, animplantable cardioverter defibrillator was not used in any of thesecases. The patients were repeatedly examined by Holter electrocardio-gram monitoring, and in the midterm follow-up (6–50 months), theystayed asymptomatic and without ventricular arrhythmia.

Conclusion: This study demonstrates the same early incidence ofcomplete heart block requiring permanent pacemaker implantation

(4%) and sustained ventricular arrhythmias following low-dose, echo-guided ASA.

AS-130Short-Term Morbidity and Mortality Follow-Up of NewlyDiagnosed Systolic Heart Failure Egyptian Patients after FirstAdmission. Basem Enany, Mustafa Alshaikha, Adel Hasanin,Ahmed Nasar. Ainshams University, Cairo, Egypt.

Background: Despite advances in therapy for heart failure (HF),outcomes remain relatively poor. This study was done to follow up theclinical course of systolic HF in Egyptian patients for 3 months aftertheir first admission for HF, including morbidity and mortality.

Methods: Sixty-nine newly diagnosed systolic HF patients wereadmitted to Ainshams University Hospital, Police Hospital, in Cairo.Seven patients did not undergo follow-up, 5 patients were excludedbecause they received previous treatment mostly related to HF, 3patients were excluded for having serious diseases with poor prognosis,and 5 patients refused to participate in the study. Thus, 49 patients wereincluded. Morbidity and mortality were identified by prospective fol-low-up of all patients.

Results: Of the 49 patients evaluated, 15 were women. Mean agewas 61.6 � 15.2 years. Mean length of stay during the first admissionwas 11.8 � 5.5 days. The 1 and 3 months mortality rates were 4.1%and 6.1%, respectively. All-cause deaths were cardiovascular in origin;66.6% of these were sudden cardiac deaths, and 33.3% were due toventricular arrhythmias. Mortality rate was higher in elderly patients�70 years (p � 0.0214), low systolic blood pressure (p � 0.0189), lowdiastolic blood pressure (p � 0.0186), and high blood urea patients(p � 0.032). Of the 46 survivors, 30.4% experienced at least 1 hospitalreadmission during follow-up. Readmission was associated more withthe following variables: low left ventricular ejection fraction % (p�0.001), poor compliance with diet and medication (p � 0.045), andhigh random blood glucose level (p � 0.035).

Conclusion: Despite the advances in treatment and diagnosticprocedures, HF still carries a grave prognosis. Length of hospital stayfor stabilization is still long. Morbidity and mortality rates are still high.There is still room for improvement in diagnostic and treatment facil-ities to reduce these rates. Patient education is important because mostdo not adhere to diet and drugs recommendations, and this is the mostcommon cause of readmission in Egypt.
