Medtronic touts stroke data from HeartWare HVAD thoracotomy study
Medtronic (NYSE:MDT) today touted stroke data from the Lateral trial of its HeartWare HVAD left ventricular assist device involving implantation via thoracotomy instead of open surgery.
With a thoracotomy implantation, surgeons insert the pump via a small, lateral incision between the left ribs and make a second small incision to accommodate the pump’s outflow graft. Fridley, Minn.-based Medtronic said Lateral results presented at the annual meeting of the American Society for Artificial Internal Organs showed that 95% of thoractomy patients were free from disabling stroke at two years.
Adverse events were more like...

Complex decision-making in stroke: preoperative mechanical thrombectomy of septic embolus for emergency cardiac valve surgery
We report a case of cardioembolic stroke in a patient with enterococcal endocarditis, with National Institutes of Health Stroke Scale score of 3. A middle-aged patient with bacterial endocarditis exhibited mild intermittent left hemiparesis and dysarthria in the setting of severe aortic insufficiency requiring urgent aortic valve replacement. Cerebrovascular imaging revealed a partially occlusive thrombus in the M1 segment of the right middle cerebral artery, which became symptomatic during relative hypotension. Given the expected hypotension during the urgently needed aortic valve replacement, there was a significant risk...

Stroke volume variation fail to predict fluid responsiveness in patients undergoing pulmonary lobectomy with one-lung ventilation using thoracotomy.
Authors: Fu Q, Zhao F, Mi W, Zhang H
Abstract
The purpose of this study was to investigate the ability of stroke volume variation (SVV) to predict fluid responsiveness in patients undergoing pulmonary lobectomy with one lung ventilation (OLV). Thirty patients intubated with double-lumen tube were scheduled for a pulmonary lobectomy requiring OLV for at least 1 hour under general anesthesia. Hemodynamic variables including heart rate, mean arterial pressure, cardiac index (CI), stroke volume index (SVI), central venous pressure (CVP) and SVV were measured before and after volume expansion (VE) (8 mL/kg of 6% hydroxy...

Goal-directed fluid therapy using stroke volume variation does not result in pulmonary fluid overload in thoracic surgery requiring one-lung ventilation.
Conclusions. SVV-guided fluid management in thoracic surgery requiring lateral thoracotomy and one-lung ventilation does not result in pulmonary fluid overload. Although oxygenation was reduced, pulmonary function remained within a clinically acceptable range.

A comparison between stand-alone left atrial appendage occlusion and resection as a method of preventing cardiogenic thromboembolic stroke
ConclusionThere were no significant differences between LAAO and LAAR in terms of the feasibility and the effectiveness as a method for stroke prophylaxis only to selected patients for both procedures, although further studies including the comparison between groups with the same backgrounds to confirm the authentic differences in the clinical results between these procedures.

Abbott Gains on Medtronic in LVAD Market
Abbott Laboratories said late-breaking clinical trial data from its MOMENTUM 3 clinical study shows its HeartMate 3 Left Ventricular Assist Device (LVAD) has improved survival and lowered rates of stroke and pump thrombosis.
The Abbott Park, IL-based company released the data during the American College of Cardiology’s 67th Annual Scientific Sessions this past weekend.
Data from MOMENTUM 3 was also published in the New England Journal of Medicine and showed patients with the HeartMate 3 LVAD had a survival rate of 82.8% at two years compared with 76.2% for those with the HeartMate II LVAD. Pump thrombosis rates remained ...

Less-Invasive Aortic Valve Replacement: Trends and Outcomes from the STS Database.
CONCLUSIONS: LI-AVR is associated with a similar operative mortality and postoperative stroke rate compared to FS. LI-AVRS should be served as a benchmark for comparison between TAVR and sAVR in low risk patients.

017 * aortic valve replacement through an anterior right mini-thoracotomy with central aortic cannulation is safe
Conclusion: MIAVR via an anterior right mini-thoracotomy with central cannulation results in similar perioperative mortality and stroke rates as compared to standard sternotomy. In addition, the MIAVR technique resulted in earlier extubation, fewer wound infections, reduced intraoperative transfusions, and shorter ICU and hospital stays. As compared to standard sternotomy AVR, our technique of MIAVR with preferential central cannulation appears safe.

Free-floating left atrial ball thrombus after mitral valve replacement with patent coronary artery bypass grafts: successful removal by a right minithoracotomy approach without aortic cross-clamp
We describe a case in a 79-year-old woman with chronic atrial fibrillation and a recent stroke who had undergone mitral valve replacement 25 years previously and coronary artery bypass grafting 5 years previously. Redo cardiac surgery represents a clinical challenge due to a higher rate of peri-operative morbidity and mortality. Median re-sternotomy can be particularly difficult in patients with functioning coronary artery grafts, where the risk of graft injury is a significant concern. Prompt surgical intervention was carried out, and to avoid the challenge of re-sternotomy in this patient with two prior thoracotomies, ...

Straight incision for extended descending and thoracoabdominal aortic replacement: novel and simple exposure with rib-cross thoracotomy
CONCLUSIONS
This new exposure with straight incision with rib-cross thoracotomy provided excellent exposures for the long segment of the thoracoabdominal aorta, and it enabled extended replacement from the ascending aorta to the abdominal aorta.

Surgical techniques for left atrial appendage exclusion
AbstractThe increasing prevalence of atrial fibrillation with the aging population and its associated major morbidity and mortality due to thromboembolic stroke have resulted in intensive research on stroke prevention or stroke risk reduction strategies. Several surgical techniques for left atrial appendage (LAA) occlusion have evolved over the past decades. Surgeons have been using different techniques leading to highly variable and, in particular, poor data on outcomes. LAA closure is performed either as a concomitant procedure during open-heart surgery or as a stand-alone surgical procedure as part of minimally invas...

Surgical repair of distal aortic arch aneurysm with distal extension: sternotomy versus thoracotomy
ConclusionsThe sternotomy approach showed better outcomes in terms of operative mortality, stroke, and pneumonia, as well as long-term survival compared to thoractomy. These results suggested that the sternotomy approach was more appropriate for patients with distal aortic arch aneurysms with distal extensions.

How Did Medtronic ’s HVAD Perform in LATERAL Trial?
Medtronic’s HeartWare HVAD pump system could get a significant boost after performing well in the LATERAL clinical trial.
The Dublin-based company presented results from the study at the American Society for Artificial Internal Organs 65th Annual Conference, that showed patients who received the system had 95% freedom from disabling stroke at two years.
The medtech giant now plans to launch a global registry to collect additional clinical evidence to further characterize survival, adverse events, and economic benefits of the HVAD System.
The HVAD Pump is a left ventricle assist device (LVAD) approved in t...
