OBJECTIVES: Subarachnoid hemorrhage (SAH) frequently prolongs QT interval in the acute phase. The purpose of our study is to investigate whether the correlation between electrocardiographic corrected QT interval and the clinical severity of SAH depends on QTc formula used. METHODS: We retrospectively studied 52 consecutive subjects with nontraumatic SAH (extravasation of blood into the spaces covering the central nervous system that are filled with cerebrospinal fluid) who were admitted within the first day of SAH. QT intervals were measured on a standard 12-lead electrocardiography and corrected by Bazett and Hodges formulae. All patients were evaluated according to clinical condition on admission by Hunt-Hess grades. The patients were grouped in two different categories according to QT interval corrected by Bazett and Hodges and scored by Hunt-Hess (HH) grades. RESULTS: Mean age of the study patients was 54 +/- 12 years and of those 31 (60%) were female. Mean values of heart rate and RR interval were 82 +/- 21 bpm and 777 +/- 163 msec, respectively. The mean QTc interval by Bazett and Hodges were 456 +/- 59 msec and 438 +/- 48 msec, respectively (P < 0.001). Twenty-three patients according to Bazett and fifteen according to Hodges had prolonged QTc. Correlation analyses showed relation between HH and QTc and prolonged QTc by Bazett (r = 0.278, P = 0.04 and r = 0.314, P = 0.024; respectively). There was no correlation between HH and QTc and prolonged QTc by Hodges (r = 0.204, P = 0.14 and r = 0.115, P = 0.41; respectively). CONCLUSIONS: In our study, correlation between QTc interval and clinical severity of SAH depended on the QTc formula used.

OBJECTIVE: In this study, we attempted to analyze the incidence and outcomes of systemic and coronary stent embolizations during percutaneous coronary interventions and have described the treatment and retrieval methods used. METHODS: We retrospectively studied 24,038 consecutive coronary angiography procedures carried out at The Baskent University Adana Hospital from 1998 to present to determine the total number of stent embolization events. RESULTS: Among them, 4,797 were consecutive coronary stent operations and embolization was encountered in 14 cases (0.29%; 95% CI = 0.14-0.44%, P < 0.0001). The mean age of the patients was 61 +/- 8 years and 78% were men. Stent embolization occurred more frequently in cases with significant proximal angulation. Calcified lesions were not noted in any of the cases. In 7 out of 14 cases, stent embolization occurred at an unknown location and the clinical course was uneventful thereafter. Treatment and retrieval methods of the other 7 cases included the following: 1. Emergency cardiac bypass surgery (3 cases, 43%) 2. Advancement of a low profile delivery balloon through the stent, inflating the balloon, and replacing the stent at the lesion site (3 cases, 43%) 3. Crushing the stent against the coronary wall using another stent (1 case, 14%) 4. 4-loop snare (1 case, failed) None of the cases had bleeding that required transfusion. The stent was not crushed or deployed in the coronary artery causing major cardiac complication in any case. CONCLUSION: Systemic and coronary embolizations of stent procedures are rare. Consequences of coronary stent embolization can lead to prompt cardiac bypass surgery if the retrieval or deployment methods fail. Stent deployment or crushing techniques may be attempted before retrieval in patients who do not suffer from coronary thrombosis and myocardial infarction due to stent embolization.

We present a case of dissection in ascending aorta (AA) accompanying dissection of the right coronary artery (RCA) during transfemoral primary coronary angioplasty (PCA) for acute inferior myocardial infarction (MI). To our best knowledge, this is the first case of dissection both in AA and RCA during angioplasty for acute MI. The dissection in RCA was caused by balloon inflation during PCA. Most probably, an angiographically invisible retro-dissection in RCA resulted in the dissection in AA. A computed tomography (CT) confirmed the diagnosis of aortic dissection that was restrained in AA. The patient was treated conservatively. Five days after the event, a control CT demonstrated that the false lumen in AA disappeared and the dissection was healed entirely.
