Transcatheter Aortic Valve Replacement Incidentalomas: A Multimodality Imaging Case of Giant Right Coronary Aneurysm.

Giant coronary artery aneurysms (CAAs) are defined as having a diameter of greater than 2 cm. We report a case of an 82-year-old male with severe aortic stenosis incidentally diagnosed with giant right coronary artery aneurysm (gRCAA) while undergoing evaluation for transcather aortic valve replacement (TAVR). It was causing a mass effect on the right cardiac chambers but was otherwise asymptomatic.

Minimally invasive coronary artery bypass grafting is associated with improved clinical outcomes.

Objective: Minimally invasive coronary artery bypass grafting (MICS CABG) via left minithoracotomy is an alternative to off-pump coronary artery bypass (OPCAB) via sternotomy. Our objective was to evaluate the clinical outcomes after MICS CABG versus OPCAB.

Methods: The medical records of patients who underwent MICS CABG from December 2009 to December 2011 and OPCAB from January 2005 to April 2011 were reviewed.

Positive inotropy due to lowering cyclic GMP is also mediated by increases in cyclic AMP in control and hypertrophic hearts.

The aim of the current study was to determine if lowering myocardial cyclic GMP by guanylate cyclase inhibition would add independently to the positive inotropic effects caused by raising cyclic AMP and if these effects are modified in left ventricular hypertrophy (LVH) produced by aortic valve plication. Isoproterenol (ISO) (0.1 mg x kg(-1) x min(-1)) was infused into a branch of the left anterior descending coronary artery of seven control and eight hypertrophy open-chest anesthetized dogs.

Altered relationship between cyclic GMP and myocardial O2 consumption in renal hypertension-induced cardiac hypertrophy.

We tested the hypothesis that preventing cyclic GMP degradation with zaprinast, (a selective cyclic GMP-phosphodiesterase inhibitor) would produce a blunted reduction in myocardial O2 consumption in renal hypertension (One Kidney-One Clip, 1K1C)-induced cardiac hypertrophy. Four groups of anesthetized open-chest New Zealand white rabbits (n = 26) were utilized. Either vehicle or zaprinast (3 x 10(-3) M) was applied topically to the left ventricular surface of control or 1K1C rabbits.

Transluminal stent-graft repair for pseudoaneurysm of PTFE hemodialysis grafts.

Purpose: To report the use of endovascular techniques to treat two cases of nonanastomotic pseudoaneurysm of a bridge graft fistula (BGF).

Methods And Results: Two men with fully functional polytetrafluoroethylene (PTFE) BGFs both presented with an enlarging mass adjacent to their arteriovenous shunt. The false aneurysm in both instances was located by ultrasound and confirmed by shunt angiography at the time of surgery.
