NCT ID: NCT01301625

Last Updated: 2018-11-07

Results Overview

Clinical Endpoint. * Cardiac death is defined as any death in which a cardiac cause cannot be excluded. (This includes but is not limited to acute myocardial infarction, cardiac perforation/pericardial tamponade, arrhythmia or conduction abnormality,cerebrovascular accident within 30 days of the procedure or cerebrovascular accident suspected of being related to the procedure, death due to complication of the procedure, including bleeding, vascular repair, transfusion reaction, or bypass surgery.) * Non-cardiac death is defined as a death not due to cardiac causes (as defined above).

Device Time is defined as the time the Steerable Guide Catheter is placed in the intra-atrial septum until the time the MitraClip Delivery System (CDS) is retracted into the Steerable Guide Catheter. Device Time is shorter in duration than Procedure Time because it does not include the time required to perform transseptal access into the left atrium.

Mitral regurgitation severity was determined based on the American Society of Echocardiography (ASE) Recommendations for Evaluation of The Severity of Native Valvular Regurgitation with Two-Dimensional and Doppler Echocardiography. MR severity was scored using the integrative method based on qualitative and quantitative echocardiographic parameters as described in the ASE guidelines.Site-assessed mitral regurgitation severity using echocardiography. MR severity was graded as follows: 0: None, 1+: Mild, 2+: Moderate, 3+: Moderate-to-Severe, 4+: Severe.

Population: A total of 36 patients had paired LVIDs measurements Because 5 patients died prior to the 12-month visit, 1 patient missed the 12-month visit, 7 patients had missing LVIDs at either baseline, the 12-month visit, or both time points and 29 patients 12-month visits were either expected or not due at the time that the ANZ trial was terminated.

LVIDs is the measurements of the left ventricular internal dimension at end-systole and normally corresponds to the smallest cardiac dimension. LVIDs is measured by transthoracic echocardiography and the results are interpreted by the study's echocardiography core laboratory.

The Minnesota Living with Heart Failure Questionnaire(MLHFQ) is comprised of 21 questions.The response for each question ranges from 0(no affect on the patient's living) to 5(affected the patient's life very much during the past month).The total score for the 21 items can range from 0-105.A lower\&higher MLHFQ score indicates less effect of heart failure\&the worse impact of heart failure on a patient's QOL,respectively.Although the MLHFQ incorporates relevant aspects of the key dimensions of QOL (physical and emotional),the questionnaire was not designed to measure any particular dimension separately.The total score should be taken as the best measure of how heart failure and treatments impact QOL. The total score is the sum of a)the physical dimension,measured using 8 questions (possible subscale score range 0-40) b)the emotional dimension,measured using 5 questions(possible subscale score from 0-25)\&c) other factors,measured using 8 questions (possible subscale score from 0-40).

Death: Defined as all causes of death for the primary safety Major Adverse Event (MAE) Endpoint. Death is further divided into 2 categories: A. Cardiac death is defined as death due to any of the following: * Acute myocardial infarction * Cardiac perforation/pericardial tamponade * Arrhythmia or conduction abnormality * Stroke within 30 days of the procedure or stroke suspected of being related to the procedure * Death due to any complication of the procedure, including bleeding, vascular repair, transfusion reaction, or bypass surgery * Any death for which a cardiac cause cannot be excluded. B. Non-cardiac death is defined as a death not due to cardiac causes (as defined above).

SECONDARY outcome

Timeframe: 30 days

Population: Two patient were lost to follow-up at the 30-day time point and 1 had been censored at Baseline. Therefore, 73 patients were included in the "at risk" population in the Kaplan-Meier freedom from death and congestive heart failure analysis at 30 days.

Death: Defined as all causes of death for the primary safety Major Adverse Event (MAE) Endpoint. Death is further divided into 2 categories: A. Cardiac death is defined as death due to any of the following: * Acute myocardial infarction * Cardiac perforation/pericardial tamponade * Arrhythmia or conduction abnormality * Stroke within 30 days of the procedure or stroke suspected of being related to the procedure * Death due to any complication of the procedure, including bleeding, vascular repair, transfusion reaction, or bypass surgery * Any death for which a cardiac cause cannot be excluded. B. Non-cardiac death is defined as a death not due to cardiac causes (as defined above). Congestive Heart Failure (CHF): Defined as a documented diagnosis of CHF on the hospital admission report or discharge summary.
