Clinical Information

Relevant Clinical History and Physical Exam

A 69 year-old Thai woman with hypertension and dyslipidemia. She presented to the emergency department with acute chest pain for 5 hrs prior to admission, chest pain radiates to left shoulder without dyspnea and orthopnea. Vital signs: BT 36.9 C BP 137/81 mmHg PR 66 bpm RR 16/min. Cardiovascular examinations are unremarkable, without jugular venous distension or murmur and gallops. Pulmonary examinations are unremarkable.

Relevant Test Results Prior to Catheterization

Electrocardiogram (ECG) was performed-showing sinus rhythm 60 bpm with ST-segment elevation in leads II, III, aVF, ST-segment depression in leads I, aVL. ECG show AV dissociation develop to 3rd degree AV block and present bigeminy ST segment elevation PVCs . CXR no pulmonary congestion . High sensitivity troponin-I was requested with highly elevated result as 1,957 ng/L. Echocardiogram showed LVEF 50%, Inferior, inferoseptal and inferolateral wall hypokinesia

Relevant Catheterization Findings

Right femoral approach with JL6/4, JR 6/4 diagnostic catheter show total occlusion mRCA, 30% stenosis at proximal-LAD, 90% stenosis at mid-LAD, 95% stenosis mid-LCx.

Interventional Management

Procedural Step

Cardiac catheterization was performed via right femoral approach with JL6/4, JR 6/4 diagnostic catheter show total occlusion mRCA, 30% stenosis at proximal-LAD, 90% stenosis at mid-LAD, 95% stenosis mid-LCx. PCI with JR 6/4. PCI to mid-RCA. GD: JR 6/4. Turntrac with Guidezilla to RCA. SC balloon 2.0x12 mm inflated mRCA up to 12 atm. Rapamycin eluting stent 3.0x18 mm deployed mRCA 12 atm with POT-PUFF sign technique. The final angiogram was acceptable result. After successful reperfusion of the right coronary artery, the premature ventricular complexes (PVCs) was subsides.

Case Summary

STEMI patterns can occasionally be observed during premature ventricular contractions (PVCs), which may assist in establishing the diagnosis of STEMI. It is important to take advantage of all available information, as PVCs can often provide valuable diagnostic clues.In this case, successful restoration of RCA flow resulted in resolution of conduction disturbances and PVCs. POT-PUFF sign technique during PCI. This method allows real-time confirmation of optimal stent expansion and apposition.
