Während der Nachbeobachtung hatte die Patientin keine Angina-pectoris-Symptomatik mehr; die Kammertachykardien konnten mittels antitachykarder Stimulation oder Kardioversion beendet werden.

A year-old woman with severely symptomatic hypertrophic obstructive cardiomyopathy was unresponsive to drug treatment. She had recurrent ventricular tachyarrhythmias and syncope and was at high risk for sudden death; a dual chamber pacemaker defibrillator DDD-ICS was implanted. Her initial left ventricular outflow tract gradient was 80 mmHg and fell to 40 mmHg during dual-chamber pacing at an atrial ventricular delay of ms.

In the follow-up over six months she was asymptomatic with respect to angina pectoris; ventricular tachycardias could be successfully terminated by antitachycardia pacing or by shocks. For long-term performance, HM was designed to require the patient only to switch on the patient device and keep it by the bedside. Transmission performance is calculated as the number of days with data transmission divided by the total number of days since the first message. Patients were evenly randomized to quarterly clinic visits Q-group or yearly clinic visits Y-group.

They were under continuous, automatic remote monitoring during the entire study. The response to HM alerts was left to the investigators' discretion. No calendar-based remote data checks or remote follow-up sessions were scheduled. Clinical follow-up schedule. Full circles indicate the phase affected by patient randomization to quarterly Q-group or yearly Y-group routine in-office ICD follow-ups.

For the whole duration of the study, all patients were under automatic, daily Home Monitoring surveillance, without calendar-based remote follow-up sessions. ICD, implantable cardioverter-defibrillator.

At the 3-month follow-up, all patients' ventricular function was re-evaluated. The devices were programmed as follows: This programming was subject to adjustments after the occurrence of a first event. Patients were followed for 2 years after the 3-month follow-up. They were instructed to refer to the investigational site for ICD-related issues and heart rhythm disorders.

Care for the patients' concomitant diseases, most prominently heart failure, was provided by specialists as clinically indicated; however, they had no role in the study. Study data were collected by staff dedicated to the trial under the direct supervision of the principal investigators.

Data management was provided by the sponsor. Data processing was supervised by the clinical team of the first author.

A follow-up examination was classified as regular if occurring within a window of 4 weeks before or after an appropriate date relative to the discharge date. At each outpatient visit, the ICD was interrogated and tested and its memory was analysed in order to adapt patient management accordingly. The generic health-related QoL was assessed by the item General Health Survey SF questionnaire at baseline, month follow-up, and month follow-up, in both study arms.

Patients were seen outside of the scheduled visits for the following pre-specified HM alerts: Patients could also be seen at unscheduled visits due to HM trend data or for any other reason, upon the patient's request or initiated by the investigator. Scheduled and unscheduled follow-up examinations were conducted similarly. To get an estimate of additional patient contacts to medical professionals, the patients were instructed to notify such visits in a diary and were interviewed at each ICD follow-up. A confirmation of this non-inferiority hypothesis would mean that the total rate of scheduled and unscheduled ICD follow-up visits would be substantially lower in the Y-group than in the Q-group.

Secondary endpoints were the intra-individual difference in QoL scores between 27 months and baseline, total and cardiovascular mortality, and the rate and duration of all hospitalizations and cardiovascular hospitalizations.

Furthermore, we made a post-hoc analysis of all available arrhythmia and therapy data 12 different items extracted from the HMSC database. The data comprised, per study group, the numbers of patients fulfilling various criteria such as having episodes in different arrhythmia zones, started or delivered therapies, or unsuccessful maximum-energy shocks. The underlying arrhythmias in this analysis were not adjudicated by the investigator.

Shock therapy was considered ineffective if the device delivered more than one shock during one arrhythmia episode, and this could include cases of repeated shocks in episodes of supraventricular tachycardia. The sample size was based on the primary study hypothesis and calculated on a Blackwelder-type test of non-inferiority.

Unscheduled ICD follow-up visits were assumed to occur independently from one other, to have a daily probability equivalent to 0. All patients with baseline QoL data were included in the intention-to-treat based QoL analysis. Due to slight post-implantation increase in patients' QoL and greater loss to follow-up in the Y-group, this approach can be considered conservative. For normally distributed continuous data verified using the Shapiro—Wilk test , mean values and standard deviations were calculated.

For non-normally distributed data, median values, interquartile ranges IQR , and mean values, if appropriate for comparison with reference data, are shown.

For categorical data, the absolute and relative frequencies were calculated. Continuous data were compared using the t -test if normally distributed or the Wilcoxon—Mann—Whitney rank test if non-normally distributed. Of patients enrolled in the study, 78 were randomly assigned to the Q-group and 77 to the Y-group. All patients had a history of myocardial infarction. At the 3-month follow-up, nine patients 5. The remaining 98 patients The median IQR follow-up duration in all patients was No other difference between groups was significant.


One patient assigned to the Y-group preferred to see the physician more often than once a year. According to the intention-to-treat principle, he was evaluated within the Y-group, with all clinic visits other than those at 3, 15, and 27 months classified as unscheduled patient-initiated follow-ups. Subsequently, HM data were received on The transmission performance did not differ significantly between the Q-group The mean median; IQR number of unscheduled follow-ups per patient-year was 0. This marked difference between the two groups can be attributed to a less need to see the affected patient outside regular follow-up schedule in the Q-group, because of the relative proximity of the next regular visit.

Reasons for unscheduled implantable cardioverter-defibrillator follow-up visits after the 3-month follow-up. The total number of scheduled and unscheduled follow-up visits after the 3-month follow-up was Q-group and Y-group. The corresponding mean median; IQR values per patient-year were 3. Of note, the total number of follow-up visits up to and including the mandatory 3-month follow-up was Q-group vs. The mean numbers of FUs per patient-year after the 3-month follow-up.

All patients were under close Home Monitoring surveillance. Cumulative number of unscheduled and total follow-up visits from post-implant discharge up to and including month follow-up. Even if not required by study protocol, 1-month follow-up was performed in most patents and is categorized as unscheduled follow-up; it had no influence on study endpoints, for it occurred before the active study period.

Thirteen patients 8. Of the patients remaining in the study after the 3-month follow-up, 70 patients experienced hospitalizations 0. There were no significant differences between the study groups in these aspects. Hospitalizations and implantable cardioverter-defibrillator therapy delivery after the 3-month follow-up. The SF questionnaire was filled out by patients at baseline, of which 54 answered the questionnaire also at the month follow-up, and 23 answered it at the month but not the month follow-up.
