TCTAP C-053 Left Main Stent Compression - An "Uh Oh" Situation

Left main coronary artery compression by an enlarged pulmonary artery.

[Left main coronary artery compression in partial endocardial cushion defect. Stent implantation].

A 42-year-old woman with Down syndrome had been diagnosed with an atrioventricular septal defect when she was an infant. The family refused a surgical intervention at that time. Three months ago, she was urgently admitted to our center with an uncontrolled non-ST-segment elevation acute coronary syndrome (NSTEACS), with extensive repolarization alterations and elevated troponin T. Because of he...

Rotational Atherectomy and Stent Implantation for Calcified Left Main Lesions

BACKGROUND Left main coronary artery (LMCA) bifurcation and heavily calcified lesions are common and challenging to treat percutaneously. Rotational atherectomy (RA) may be beneficial in this setting to facilitate stent placement though direct supporting evidence is lacking. This study sought to analyze patients who underwent RA of the LMCA. METHODS Consecutive cases involving RA of the LMCA ...

septum and narrow tract), which would cause increased enddiastolic pressure.6 3. Localized or multivessel coronary spasm. 4. Microcirculation alterations. 5. Myocarditis. 6. Self-limiting, acute coronary syndrome in patients with LAD recurrent segment that irrigates an extensive apicaldiaphragmatic region, but with a lesion in the middle portion not visualized on angiography, but seen on intrav...

Left main coronary stent positioning using rapid transcoronary pacing.

Temporary transcoronary unipolar pacing is a validated simple, effective, and safe alternative to temporary transvenous pacing of the right ventricle for the treatment of relevant bradyarrhythmias complicating percutaneous coronary intervention. We describe the use of rapid transcoronary pacing to aid precise placement of a stent in the left main coronary artery bifurcation.
