Epicardial Tachosil Patch Repair of Ventricular Rupture in a 90-Year-Old After Mitral Valve Replacement

Surgical management of severe mitral annular calcification

BACKGROUND

Surgical management of severe mitral annular calcification (MAC) presents a challenging problem for even the most experienced surgeons. Preoperative planning is the most effective strategy to mitigate risk in these scenarios. MAC alone should not disqualify a patient from consideration for mitral valve repair, although the presence of concurrent greater than moderate stenosis warrants consideration of mitral valve replacement.

METHODS

While repair and replacement techniques for mitral regurgitation in the setting of MAC overlap with those used to repair a non-calcified mitral apparatus, there are unique considerations to the surgical conduct of these procedures. Specifically, this article describes techniques that may be employed when the severity of MAC precludes typical repair or replacement strategies.

RESULTS

Between 2014 and 2021, 77 patients were operated on by a single surgeon for mitral valve disease complicated by severe MAC. Using the systematic approach described herein, 1-year mortality was 7.8% and overall mortality over a follow-up period extending 1 to 8 years was 9.1%.

CONCLUSIONS

Despite the inherent challenges of mitral valve repair or replacement in the setting of severe MAC, a systematic approach beginning with preoperative planning, modification of annular suture placement, and techniques to mitigate severe complications have, in our experience, resulting in a reliable methodology for managing severe MAC with excellent outcomes.

Use of the EVARREST patch for penetrating cardiac injury

Penetrating cardiac injuries have a pre-hospital mortality of 94% with a subsequent in-hospital mortality of 50% among initial survivors (Leite et al., 2017 [1]). The Western Trauma Association (WTA) guidelines recommend resuscitative thoracotomy (RT) for patients with penetrating torso trauma and less than 15 min of cardiopulmonary resuscitation (CPR) Burlew et al. (2012) [2]. Penetrating cardiac injuries are classically repaired using skin-stapling devices and/or suture repair with or without pledgets (Wall et al., 1997 [3]). In this study, we present a case of penetrating cardiac injury where all the aforementioned techniques failed, and a new approach was explored. A fibrinogen/thrombin patch was used in this clinical setting, which is an off-label use of the product, we here present our encouraging outcome.

[Use of topical haemostatic agents in cardiovascular surgery]

The problem of haemostasis in cardiovascular surgery is of current concern. Recent trends are towards increased use of topical haemostatic agents. Tachocomb has been used for more than 30 years in abdominal surgery and oncology. The purpose of the present publication is to analyse the literature data and formulate the indications for the use of Tachocomb in cardiovascular surgery. Multicenter randomized and local studies have demonstrated efficacy of Tachocomb in treatment of surgical haemorrhage in operations on the heart, thoracic aorta, carotid arteries and lower-limb arteries, resulting in significantly decreased time to achieve haemostasis, decreased volume of blood loss and haemotrasfusion, as well as reduced frequency of complications. Also shown was economic efficacy, including a shortened length of patients' hospital stay. This is followed by describing a wide spectrum of examples of alternative use of Tachocomb, including its use for seamless closure of defects of cardiac chamber walls, aero- and lymphostasis, prevention of formation of commissures. Convincing experimental and clinical results make it possible to formulate a series of indications for the use of Tachocomb in cardiovascular surgery.

Cost analysis of pulmonary lobectomy procedure: comparison of stapler versus precision dissection and sealant

OBJECTIVE

We aimed to evaluate the direct costs of pulmonary lobectomy hospitalization, comparing surgical techniques for the division of interlobar fissures: stapler (ST) versus electrocautery and hemostatic sealant patch (ES).

METHODS

The cost comparison analysis was based on the clinical pathway and drawn up by collecting the information available from the Thoracic Surgery Division medical team at Mantova Hospital. Direct resource consumption was derived from a previous randomized controlled trial including 40 patients. Use and maintenance of technology, equipment and operating room; administrative plus general costs; and 30-day use of postsurgery hospital resources were considered. The analysis was conducted from the hospital perspective.

RESULTS

On the average, a patient submitted to pulmonary lobectomy costs €9,744.29. This sum could vary from €9,027 (using ES) to €10,460 (using ST). The overall lower incidence (50% vs 95%, P=0.0001) and duration of air leakage (1.7 days vs 4.5 days, P=0.0001) in the ES group significantly affects the mean time of hospital stay (11.0 days vs 14.3 days) and costs. Cost saving in the ES group was also driven by the lower incidence of complications. The main key cost driver was staff employment (42%), then consumables (34%) and operating room costs (12%).

CONCLUSION

There is an overall saving of around €1,432.90 when using ES patch for each pulmonary lobectomy. Among patients undergoing this surgical procedure, ES can significantly reduce air leakage incidence and duration, as well as decrease hospitalization rates. However, further multicenter research should be developed considering different clinical and managerial settings.
