An Open Label,Observational, Real Time Data Capturing of Usage & Outcome of Coseal

An Open- Label,Multicentre, Observational, Prospective, Real-time Data Capturing of Usage, Outcome & Physician Satisfaction of Coseal in Cardio- Vascular- Thoracic Operative and Re- Operative Procedures

This study is Open- Label, Observational, Prospective, Real-time data capturing of Usage, Outcome & Physician satisfaction of Coseal in Cardio- Vascular-Thoracic Operative and Re- Operative procedures.

Objective of this study is to assess current practice pattern and best practice sharing of usage of Coseal by collecting data on (1) Sealing suture lines along arterial and venous reconstruction(2) Patients undergoing cardiac surgery to prevent or reduce the incidence, severity and extent of post surgical adhesion enforcement of suture lines in lung resection procedures (3) From this data to document and generate a real life experience on the use of Coseal in cardio vascular and thoracic surgery.

Number of expected patient enrollment is 750 from 20 participating sites.

Objectives:

• Assessing current practice pattern and best practice sharing of usage of Coseal as per IFU by collecting data on oSealing suture lines along arterial and venous reconstructions oPatients undergoing cardiac surgery to prevent or reduce the incidence, severity and extent of post surgical adhesion enforcement of suture and staple lines in lung resection procedures
• From this data to document and generate a real life experience on the use of Coseal in cardio vascular and thoracic surgery
• To possibly create a guideline for usage of Sealant in routine practice in India
• To study delivery methods and clinical impact in minimally invasive surgery like VATS and robotic surgery

End points

Primary Endpoint

1. Cardio vascular sealing:

   To report the effectiveness and safety of COSEAL in the control of anastomotic suture line and needle hole suture bleeding during vascular reconstruction by checking the incidence of immediate anastomotic sealing and the presence of persistent intra-operative and postoperative bleeding average time to achieve hemostasis for a single bleeding site after 60 s of clamping without manual compression In case of sternotomy, Hemostasis time in mns, which is operative time comprised between the removal of cardio-pulmonary bypass cannulae and the closure of the sternum.

   Overall postoperative bleeding in mL/m² revision for bleeding Minor complications, major complications, mortality

2. Efficacy of Coseal in prevention or reduction of adhesion in re-do surgeries for patients with staged operations for congenital cardiac malformation re-operated on during the follow-up period of the registry

   Incidence of adhesions. location and extension of adhesion by measuring the percentage of surface affected for each of the following regions: pericardial or retrosternal, inferior or diaphragmatic region, right lateral or atrial region, region around the great vessels, pulmonary surface.

   Overall evaluation (dissection easy or difficult) Incidence of subjects free of adhesions.

   Severity (at each of these sites, the adhesions will be graded as follows:

   absence of adhesion; 1: filmy and avascular; 2: dense and/or vascular; and 3: cohesive)

3. Air leak: incidence of immediate (at the time of closure) and prolonged post-operative air leak, Use in redo surgery for air leak.

Secondary Endpoints

1. Cardiovascular (sealing and adhesion prevention):

   1. Total operative time
   2. Nature and duration of first operation
   3. Nature and duration of redo operation, and time for dissection from sternotomy to end of dissection for prevention of adhesions )
   4. Length of intensive care stay
   5. Length of hospital stay
   6. Infection rate
   7. Quality of wound healing
   8. Quality of life (SF36)

2. Thoracic and Lung

   1. Sealing the suture/ staple line on table Use of buttressing
   2. Total operative time
   3. Drain output
   4. Drain duration
   5. Length of hospital stay
   6. Prolonged air leak (more than 5 days) (>5 days is the new standard for prolonged aire leak accepted in 2011 by the EU Soc of CVTS, see ref.)
   7. Infection rate

3. In all cases,

   1. intra and post-operative blood loss
   2. FFP, Transfusion
   3. Reoperation for bleeding purpose

4. Others

   1. Surgeons satisfaction
   2. Easiness of product handling during application (VAS)

Inclusion Criteria:

1. Patients undergoing cardiovascular and thoracic surgery who require use of Coseal as a treatment strategy.
