Fulltext Combined repair of aortic arch aneurysm and coronary artery bypass grafting via a modified clamshell incision

Eng JB

Med J Malaysia, 2007 Jun;62(2):177-8.

A 58 year-old man presented with a large aneurysm of the aortic arch and severe coronary artery disease. He underwent combined repair of the aortic arch aneurysm and coronary artery bypass grafting via a modified clamshell incision using deep hypothermic circulatory arrest and retrograde cerebral perfusion. He made an uncomplicated postoperative recovery. The operative techniques are discussed with a review of the relevant literature.

A Flowmeter Technique to Exclude Internal Mammary Artery Anastomosis Error in an Arrested Heart

The revision of an internal mammary artery graft anastomosis because of a technical error can be time-consuming and complicated and may lead to complications. Here, we describe the technical details and our early experience of using a standard transit-time flowmeter to exclude technical errors and facilitate rapid decision making for anastomosis revision in an arrested heart during aortic cross-clamping in the absence of ultrasound guidance.

Hypertrophic obstructive cardiomyopathy: the mitral valve could be the key

Dulguerov F, Marcacci C, Alexandrescu C, Chan KM, Dreyfus GD

Eur J Cardiothorac Surg, 2016 Jul;50(1):61-5.

PMID: 26792931 DOI: 10.1093/ejcts/ezv473

OBJECTIVES: As we strongly believe that treating the mitral valve abnormalities is a key feature of hypertrophic obstructive cardiomyopathy (HOCM), we have systematically corrected both the anterior and posterior leaflet (PL) size and geometry. We have analysed our immediate results and at mid-term follow-up.

METHODS: From March 2010 until June 2015, 16 patients with HOCM underwent surgical correction of obstruction. The mean age was 51 years old (range, 32-72 years). All were symptomatic being New York Heart Association (NYHA) class 3 (n = 4) or 4 (n = 12). All had systolic anterior motion at echocardiogram with severe mitral regurgitation (MR). Intraventricular gradient preoperatively was 73.5 mmHg (range, 50-120 mmHg). All patients underwent a double-stage procedure: first septal resection through (i) the aortic valve and (ii) the detached anterior leaflet (AL) of the mitral valve and at second, mitral valve repair by (i) reducing PL height (leaflet resection or artificial neochordae) (ii) increasing AL height with pericardial patch.

RESULTS: There was no in-hospital or late death. All patients were Class 1 NYHA at latest follow-up. Control echocardiography showed no MR, mean rest intraventricular gradient was 15 mmHg (range, 9-18 mmHg).

CONCLUSIONS: Our good mid-term results support the concept that HOCM is not only a septal disease and that the mitral valve pathology is a key component that should be addressed. For most patients, the ideal surgical treatment should consist in a two-step procedure. It is even necessary to be studied whether treating the mitral valve alone could not suffice.

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.

Dermacyn irrigation in reducing infection of a median sternotomy wound

Mohd AR, Ghani MK, Awang RR, Su Min JO, Dimon MZ

Heart Surg Forum, 2010 Aug;13(4):E228-32.

PMID: 20719724 DOI: 10.1532/HSF98.20091162

Sternal wound infection is an infrequent yet potentially devastating complication following sternotomy. Among the standard practices used as preventive measures are the use of prophylactic antibiotics and povidone-iodine as an irrigation agent. A new antiseptic agent, Dermacyn super-oxidized water (Oculus Innovative Sciences), has recently been used as a wound-irrigation agent before the closure of sternotomy wounds.

Cryopreserved mesenchymal stromal cell treatment is safe and feasible for severe dilated ischemic cardiomyopathy

Chin SP, Poey AC, Wong CY, Chang SK, Teh W, Mohr TJ, et al.

Cytotherapy, 2010;12(1):31-7.

PMID: 19878080 DOI: 10.3109/14653240903313966

Bone marrow (BM) mesenchymal stromal cells (MSC) represent a novel therapy for severe heart failure with extensive myocardial scarring, especially when performed concurrently with conventional revascularization. However, stem cells are difficult to transport in culture media without risk of contamination, infection and reduced viability. We tested the feasibility and safety of off-site MSC culture and expansion with freeze-controlled cryopreservation and subsequent rapid thawing of cells immediately prior to implantation to treat severe dilated ischemic cardiomyopathy.
