Surgical treatment of acutely thrombosed mechanical mitral valve
Cardiothoracic Surgery, Faculty of Medicine, Al-Azhar
Acute thrombosis of mitral valve prosthesis is a life
threatening complication. Data on complications and outcome are
limited. Objective: to evaluate surgical treatment of
acute prosthetic mitral valve thrombosis regarding indications,
contraindications, complications and outcome. Patients and
methods: Between March 2011 and December 2013, thirty
patients with acute thrombotic mitral valve prostheses were
admitted to Al-Hussein University Hospital. All patients were
subjected to complete history, examination and investigations.
Exposure of the mitral valve was done via the standard left
atriotomy in 12 patients (40%) and right atrial trans-septal
approach in 18 patients (60%). Results: Thrombus was
found in 5 patients (16.67%), pannus alone in 10 patients
(33.34%), thrombus and pannus together were found in 15 patients
(50%). A biological valve was implanted in 5 patients (17%)
while in 25 patients a mechanical valve was implanted (83%).
Tricuspid valve repair was done in 18 patients using De-Veg
technique. Conclusion: Prosthetic valve thrombosis (PVT)
is a potentially fatal complication of heart valve replacement.
These acceptable results suggest that early surgical
intervention might be a safe and effective treatment of choice
in patients with PVT. Patients with mechanical valve prostheses
should be informed adequately about the need for, and the
importance of, an effective anticoagulation regimen.

Severely diseased left anterior descending coronary artery (LAD)
is a surgical challenge and several procedures were suggested to
achieve adequate reconstruction. Aim of the work: The
aim of this study is to assess safety and surgical outcome of
the use of patch angioplasty for the reconstruction of severely
diseased LAD. Material and methods: In the period between
January 2009 and January 2012, 40 patients (mean age 53.9 +
7.9 years, 62.5% males) were chosen for reconstruction of a
diffusely diseased left anterior descending coronary artery
(LAD) with either left internal mammary artery (LIMA) patch or
saphenous vein patch. Other associated significant coronary
artery lesions were classically grafted with Inverted saphenous
vein. Results: LAD patch was feasible in all cases and
varied in length from 2-8 cm (4.8 + 1.4cm). Mean
number of arterial and venous grafts was 2.1 + 0.64, mean
aortic cross-clamp time and bypass times were 60.8+ 18.2
and 80.2 + 23 minutes, mean ICU and hospital stays were
44.9 + 10.3 hours and 9 + 3.2 days; respectively.
There were one hospital mortality and one complications by deep
sternal wound infection, patients were followed up from 1 month
to 3 months. Mean postoperative NYHA class (1.2 + 0.4)
significantly improved, compared to the preoperative values (3.5
+ 0.51; P<0.001). Conclusions: the use of
LAD patch angioplasty is generally feasible and a safe
alternative for the reconstruction of severely diseased LAD.
