Unravelment of Medtronic Onyx stent during bifurcation stenting using the jailed wire technique; An adverse effect of helical stent structure?

Leenders GE, Liew HB, Stella PR

Cardiovasc Revasc Med, 2018 12;19(8S):58-59.

PMID: 30115559 DOI: 10.1016/j.carrev.2018.03.016

A 62-year old male underwent treatment of a bifurcation lesion in the left anterior descending coronary artery using provisional stenting with a jailed wire technique. Severe longitudinal stent deformation and unravelment of the stent part proximal of the bifurcation occurred when we tried to pull the jailed wire from the side branch. The described case poses a caution on the use of this specific stent(-design) in bifurcation lesions.

Self-Practice Program for Beating-Heart Minimally Invasive Coronary Anastomosis Using a Homemade Low-Fidelity Simulator: A Proof of Concept

OBJECTIVE: We evaluated the effectiveness of a consistent and structured self-practice coronary anastomosis program using a homemade low-fidelity beating-heart simulator.

METHODS: An intermediary trainee was subjected to an 8-week structured self-practice program. The program was divided into 2 parts of nonbeating and beating practices with a minimum number of timed anastomoses. Each part was followed by an assessment using an objective skills assessment tool score. The beating-heart simulator was built using motorized toy blocks connected wirelessly to a smartphone application. This was coded to enable rate selection. A junior consultant was compared to the subject at the end of the program. Both were tasked to perform 1 coronary anastomosis for both off-pump coronary artery bypass (OPCAB) and minimally invasive CAB (MICS) setup. The primary outcomes were anastomotic time and score compared with the junior consultant. Secondary outcomes were progression of anastomotic time and score throughout the program.

RESULTS: Overall performance of the studied subject approached the performance of the junior consultant in terms of time (OPCAB, 489 vs 605 s; MICS, 712 vs 652 s) and scores (OPCAB, 21 vs 20.7; MICS, 19 vs 20.6). There were inverse correlations between anastomosis time and number of practices for both nonbeating and beating anastomoses. Overall improvement was observed in terms of assessment scoring by 26.6%.

CONCLUSIONS: A structured self-practice program using an affordable and accessible simulator was able to help trainees overcome the MICS anastomosis learning curve quicker when introduced earlier. This may encourage earlier adoption of MICS among surgeons.

Novel active fixation mechanism permits precise placement of a left ventricular lead: early results from a multicenter clinical study

Yee R, Gadler F, Hussin A, Bin Omar R, Khaykin Y, Verma A, et al.

Heart Rhythm, 2014 Jul;11(7):1150-5.

PMID: 24801899 DOI: 10.1016/j.hrthm.2014.04.020

Left ventricular (LV) lead implantation for cardiac resynchronization therapy (CRT) is associated with lead dislodgement rates ranging from 3% to 10%, and some implant approaches to prevent dislodgement may contribute to suboptimal CRT response. We report our early human experience with an LV lead with a side helix for active fixation to the coronary vein wall.

Effect of bradykinin and its antagonist on survival time after coronary artery occlusion in rats

Atif Abbas S, Sharma JN, Pauzi A, Yusof M

Gen. Pharmacol., 1999 Sep;33(3):243-7.

PMID: 10480657

The present study was conducted to examine the effect of bradykinin and bradykinin 2 receptor antagonist on survival time in rats with coronary artery ligation for 15 min and continuously. We also evaluated the heart rate and blood pressure responses in the presence and absence of bradykinin and its antagonist. Bradykinin treatment (4 microg and 8 microg/kg IV) significantly (p < 0.05) increased the survival time of rats compared with saline-treated rats with coronary artery ligation for 15 min and continuously. The heart rate and blood pressure responses were significantly (p < 0.001) altered in the presence of coronary artery ligation. Bradykinin antagonist treatment (4 microg/kg IV) abolished the effect of bradykinin and thus reduced the survival time of rats with coronary artery ligation. The mean value of survival time between saline-treated and bradykinin antagonist- plus bradykinin-treated rats did not differ significantly (p > 0.05).

Coronary artery bypass graft surgery in a young female with systemic lupus erythematosus and its operative challenges: A case report

Gurpreet S, Vendargon SJ, Syed Rasul SH

Med J Malaysia, 2019 12;74(6):549-550.

PMID: 31929487

We understand that autoimmune disorders such as Systemic Lupus Erythematosus increases the likelihood of developing coronary heart disease. However, its implications on patients undergoing cardiac surgery is not well understood. Here we present a female patient with SLE who developed coronary artery disease at a young age and underwent coronary artery bypass graft surgery. As SLE is associated with vasculitis, we wanted to understand regarding the choice of conduit as well as its long term patency. Also whether percutaneous angioplasty has a role to play in patients with SLE.
