Automated Algorithm Based Analysis of Phonocardiograms of Newborns

Heart MurmursMitral Valve Prolapse1 more

The purpose of this double-blind pivotal clinical utility study is to determine on a large patient population whether heart murmurs can be reliably detected with high sensitivity and specificity using a locked, automated algorithm-based phonocardiogram analysis (also referred to as computer aided auscultation (CAA)). Each patient is auscultated and diagnosed independently by a medical specialist. Additionally, for each patient, an echocardiogram is performed as the gold-standard for determining heart pathologies. The CAA results are compared to the findings of the medical professionals as well as to the echocardiogram findings. Hypothesis: The specific (locked) CAA algorithms used in this study are able to automatically diagnose pathological heart murmurs in premature babies and newborns with at least the same accuracy as experienced medical specialists.

Automatic Differentiation of Innocent and Pathologic Murmurs in Pediatrics

Heart MurmursMitral Valve Prolapse1 more

The purpose of this preliminary clinical study is to assess the quality of a computational algorithm that automatically classifies murmurs of phonocardiograms (PCGs) as either pathologic (AHA class I) or as no- or innocent (AHA class III) in the pediatric population. Each patient is auscultated and diagnosed independently by a medical specialist by means of a standard mechanical stethoscope. Additionally, for each patient, a PCG is recorded using a Littmann 3200 electronic stethoscope and later analyzed using the computational algorithm. An echocardiogram is performed as the gold-standard for determining heart pathologies. The results of the computer aided auscultation (CAA) are compared to the findings of the medical professionals as well as to the echocardiogram findings. Hypothesis: The specific CAA algorithms used in this study are able to differentiate pathologic (AHA class I) from no- or innocent murmurs (AHA class III) in a pediatric population.

Operative Mitral Valve Reconstruction in Functional mv Insufficiency With Reduced Systolic Ventricle...

Mitral Valve InsufficiencyLeft Ventricular Systolic Dysfunction1 more

Functional mitral insufficiency poses a challenge with regard to the optimal time of intervention, particularly because they are frequently associated with left ventricular (LV) dilation and reduced LV ejection fraction (EF). The registry will document the underlying pathology by using transthoracal echo cardiography (TTE) with analysis of common tenting parameters. OP strategies, data and outcomes will be documented, as well as follow-up data for echocardiography, quality of life and MACCE outcomes after 6 months, 1 and 2 years.

Cardiac Output Pulmonary Arterial Catheter Compared to FloWave™ 1000

Congestive Heart FailureIschemic Cardiomyopathy4 more

The purpose of this study is to compare cardiac output results obtained using the thermodilution push technique with the Pulmonary Arterial Catheter (PAC) to the predicted cardiac output results obtained from the non-invasive FloWave™ 1000 device.

Patient Specific Mitral Valve Modeling for Surgical Planning and Training

Mitral Valve ProlapseMitral Regurgitation1 more

Mitral valve disease is a common pathologic problem occurring in approximately 2% of the general population but climbing to 10% in those over the age of 75 in Canada[1]. This project has three primary goals all of which will positively affect cardiac patient care. 1) Create patient specific MV models for complex repairs that will allow surgeons the opportunity to practice the repair. 2) Potentially predict the outcomes following minimally invasive repair techniques such as transcatheter treatments (e.g., MitraClip). 3) Provide a model to train individuals on mitral valve repair techniques.

Using Pulse Counter Vigileo-Flotrac System in Transapical Off-pump Minimally Invasive Mitral Valve...

Mitral Valve Prolapse

Minimally invasive transapical off-pump chordae implantation includes features such as tachycardia, arrhythmia, hemorrhage, sudden hemodynamic changes caused by the device moving in the left ventricle and the atrium, for anesthetists. In this observational study, the investigators presented the investigators's hemodynamic recuperation and anesthesia experiences revealed by cardiac output measurement after transapical mitral valve repair.

Primary Mitral Regurgitation Repair

Mitral Valve InsufficiencyMitral Valve Prolapse6 more

This longitudinal cohort study evaluates the relationship of myocardial tissue markers characteristics assessed by cardiac MRI, with clinical measures of symptoms and functions in adults with primary mitral regurgitation. Participants are followed conservatively or may choose to undergo surgical repair at the discretion of their clinical team.

Exercise Capacity Evaluation in Patients With Non-rheumatic Mitral Valve Prolapse (MVP)

Mitral Valve Prolapse

Mitral valve prolapse (MVP) is a relatively common cardial problem in which one or more of the leaflets of the mitral valve prolapse during systole into the left atrium. The disease is very heterogeneous and can vary from a benign disease with almost no impact on the patient's life to a severe cardiac problem with many complications and high mortality rate. The purpose of the study is to see if the investigators can find a relation between the severity of the MVP to the exercise capacity of the patient. The investigators also want to see if they can find a difference between the exercise capacity of mild MVP patients and healthy people. To evaluate the exercise capacity of the subjects the investigators use Cardiopulmonary Exercise Testing (CPET). CPET is probably the best known way to get a full picture of the subject's functions during exercise. By combining gas exchange monitoring and ECG during a controlled exercise in which the subject reaches maximal effort, the test gives information about the cardiac, the pulmonary and the metabolic functions of the subject. This information can help identify if there is a problem to perform exercise properly and more specifically if the limitation is due to a cardiac, pulmonary or metabolic problem.
