Background. Exercise causes enhanced sympathetic discharge and results in physiologic tachycardia. However, in some patients with a diseased conduction system resulting from acute ischemia, exercise can precipitate heart block. Methods and results. In this report we describe a 51 years old male patient with transient advanced degree atrioventricular (AV) block developed during recovery from exercise stress testing, resolved after the administration of atropine. Nuclear perfusion imaging demostrated stress-induced ischemia of the inferior-apical segments, and recovery of perfusion in the images obtained at rest. Coronarography showed critical stenosis of the right coronary artery, which was treated by percutaneous coronary intervention (PCI) and drug eluting stent (DES) deployment. Conclusion. Nuclear myocardial perfusion imaging provides noninvasive evidence that transient ischemia of the infero- apical segment can result in advanced degree AV block in patient with critical severe right coronary disease.

A 75-year-old woman with past medical history of coronary bypass, atrial fibrillation, mitral valve repair undergoes percutaneous coronary intervention of left circumflex artery with a drug eluting stent. An Angio-Seal vascular closure device was used post procedure to obtain hemostasis. Shortly after deployment, frank bleeding was observed necessitating manual compression at the arteriotomy site. After hemostasis was achieved, the right lower extremity was found to be pale, bluish with feeble pulses. Doppler ultrasound was emergently performed revealing decreased blood flow after mid superficial femoral artery (SFA) and an echo lucent object lodged luminally in the SFA. Patient was urgently taken to the vascular laboratory where an Angio-Seal device, including the collagen plug and anchor, was successfully removed endovascularly patient made full recovery and was discharged home the following day.

AbstractSitus inversus with dextrocardia is a rare condition, with complete transposition of all the body organs, including the heart. Percutaneous coronary intervention (PCI) in these patients is technically difficult because of the mirror image of organs. Here, we describe a 56-year-old man with coronary heart disease with known situs inversus with dextrocardia and coronary percutaneous intervention was performed for stenosis in the right coronary artery. A drug eluting stent was implanted at this site successfully. This case suggested that the interventional management of such patients follows the same general rules as for non-dextrocardia patients, but the manipulation of the catheter and projection position choices need to be taken into consideration to obtain optimal benefits for the patient.

A 62-year-old man with effort angina underwent percutaneous coronary intervention in our hospital. The target lesion was severely calcified at the mid part of the right coronary artery. Pre-procedural intravascular imaging and optical frequency domain imaging showed a calcified nodule at the lesion. We performed rotational atherectomy with a 2.0 mm burr and observed an increase in the lumen area; however, a large amount of calcified nodule persisted. We decided to perform rotational atherectomy with a burr size of 2.25 mm; however, distal embolization of the calcified nodule occurred. We failed to retrieve the embolus; hence, we performed balloon dilatation with a 2.0-mm balloon, which was successfully performed. Yet, the lesion with the embolus immediately recoiled. Finally, a drug-eluting stent was implanted in both the distal lesion with the embolus and the lesion with the calcified nodule. Final coronary angiography showed good results. We confirmed good stent expansion and that calcified nodule was compressed outside the stent. Atherectomy of a calcified nodule is effective at achieving sufficient stent expansion and reducing the risk of vessel perforation. However, we experienced distal embolization of the calcified nodule at the time of rotational atherectomy and so distal embolization should be considered at the time of treatment of calcified nodule.
