Among those, myxoma is the most common cardiac tumor. There are only a few reports of such tumors from Turkey. We report our experience with 67 patients with primary cardiac myxoma operated on at our institute between December 1990 and October 2006. The study group comprised 22.38% males and 77.61% females with a mean age of 46.29 (+/-18.29) years. The predominant symptoms were dyspnea and palpitation. In addition, 3 patients presented with peripheral embolism with impending limb ischemia that necessitated emergency embolectomy. Echocardiography was generally enough for the demonstration of the myxomas. Two sporadic myxomas (%2.98) and one familial myxomas (1.49%) presented with recurrence. There were three (4.47%) hospital mortalities. Two patients (2.27%), with preoperative decompensation, died after tumor resection, from progressive low cardiac output. One patient, with preoperative massive pulmonary embolus, died two days after operation, from right ventricle insufficient. In conclusion, we herein summarized surgical results with primary cardiac myxomas. Surgical excision of primary cardiac myxomas tends to show excellent results after surgical excision.

Methods: We compared PWD in patients with acute ischemic stroke (n = 50) with age-matched healthy subjects (n = 46) as controls. Twelve-lead electrocardiograms of all patients were obtained and PWDs were measured. Left ventricular diameters and functions were also obtained in transthoracic echocardiography. Results: The demographic properties of patients were similar in two groups. P wave dispersions were significantly longer in patients with acute ischemic stroke than control subjects (77±26 ms and 63±21 ms, respectively, p = 0.007). The left ventricular end-systolic, end-diastolic diameters and ejection fraction were similar between two groups. The interventricular septal diameter and left atrial diameters were significantly higher in patients with acute ischemic stroke than control group. Conclusions: This study demonstrates that prolonged PWD have a relationship with acute ischemic stroke. Prolonged PWD may be an independent predictor of ischemic stroke.

The tumor was detected by echocardiography and resected along with part of the septal leaflet, followed by primary repair.

The pulmonary veins, inferior vena cava, and left superior vena cava drained into the left-sided morphologically right atrium. Only the right superior vena cava drained into the right-sided morphologically left atrium. Intraatrial baffle repair was performed successfully.

There were 31 female and 13 male patients. The myxoma arose from the interatrial septum in 43 patients and from the annulus of the posterior leaflet of the mitral valve in one patient. Preoperatively, all patients had dyspnea or tachycardia. Clinical evidence of systemic embolism was detected in 9 patients. The diagnosis was established by angiocardiography in 6 patients and by echocardiography in 38 patients. All patients were treated surgically under cardiopulmonary bypass and the myxomas were resected with their septal attachments. The septal defects were closed with a patch in 12 patients and primarily in 32 patients.

Overall hospital mortality was 10.6% (16/151). The total cumulative follow-up period was 527.6 patient-years with a mean of 4.34 ± 2.53 years and a range of 2 months to 10.9 years. During the follow-up period, 27 patients (5.11% per patient-year) developed bioprosthesis dysfunction of whom 26 were reoperated and one was treated medically, 4 patients had thromboembolic complications (0.75% per patient-year), one patient (0.18% per patient-year) had anticoagulant-related bleeding, and two patients (0.37% per patient-year) had a paravalvular leak (one was reoperated). Total valve-related complications were 6.44% per patient-year. Late mortality was 2.65% per patient-year (14/151). Ten-year actuarial survival was 78.5%. Freedom from bioprosthesis dysfunction was 56.6%, from thromboembolic complications 95.8%, and from all complications 49.6%. Our findings of a...

The patients were divided into three groups of 60 each: group 1 required no inotropic support; group 2 had mild inotropic support with dopamine; group 3 had high-dose inotropic support with adrenalin and dopamine. Thirty-eight patients in group 1 (63%), 40 in group 2 (67%), and 32 in group 3 (53%) responded to one or two doses of diltiazem. There was no difference between the groups in terms of the success rate of the treatment (p > 0.05). Additional procedures were needed in 70 patients including cardioversion in 20 (12 in group 1, 8 in group 2). Mean cardiac index was significantly increased and mean pulmonary artery pressure was significantly decreased in all three groups after diltiazem treatment. After the first dose of diltiazem (0.25 mg·k...

The ages of the patients ranged from 10 to 39 years (mean 25.2 ± 8.82). Nine patients had cardiac and pericardial cysts, and the first patient of this series had two pericardial cysts. One patient died in the early postoperative period due to rupture of the interventricular septum. Hospital mortality was 10% (1/10). Late follow-up data were obtained for 8 of the 9 hospital survivors, and no recurrence was found.

Ça lış ma pla nı: Ocak 1990-Aralık 2015 tarihleri arasında mekanik kalp kapak replasmanı yapılan gebe kadınlarda antikoagülan tedavi rejimleri, retrospektif olarak incelendi. Mekanik kalp kapak replasmanı sonrası 57 hastada 72 gebelik gözden geçirildi ve dört farklı rejim belirlendi ve gebeliğin farklı trimesterlerinde değerlendirildi. Bul gu lar: Yetmiş iki gebeliğin, 40'ı sağlıklı yeni doğanla, 35'i (%48.6) sağlıklı yenidoğan, dördü (%5.6) prematüre doğum ve biri (%1.4) düşük doğum ağırlığı ile sonuçlandı. On sekiz (%25) terapötik ve 12 (%16.7) spontan düşüğün yanı sıra, iki (%2.8) ölü doğum izlendi. Gebelik süresince veya post-partum dönemde, yedi gebede kapak trombozu gelişti. Altı hastada (%10.5) kanama ve yine altı (%10.5) hastada periferik emboli meydana geldi. Maternal mortalite görülmedi. So nuç:Gebelik sırasında en ideal antikoagülasyon rejimine ilişkin tam bir fikir birliği olmamasına rağmen, birinci trimesterde varfarinin teratojenisite ve artmış düşük riskini önlemek için doz ayarlamalı fraksiyone olmayan heparin veya düşük molekül ağırlıklı heparin ile değiştirilmesi uygundur. Düşük molekül ağırlıklı heparinin uygulaması kolaydır ve güvenilir bir şekilde izlenebilir ve başarılı gebelik sonuçlarına da vesile olabilir. Ancak, gebeliğin tüm trimesterleri süresince, günde ≤5 mg varfarini geçmemek kaydıyla kullanılacak varfarin, embriyopati riskinin gebe tarafından kabul edildiği durumlarda, alternatif bir seçenek olabilir. Anah tarsöz cük ler: Antikoagülasyon; mekanik kalp kapağı; gebelik.

We present our early and late-term experience with 110 patients with aortic regurgitation (AR) who underwent aortic valve repair (AVr) or valve-sparing aortic root surgeries (VSARS) due to aortic dissection or aortic aneurysm. Methods: Nine hundred eighty-two patients who underwent aneurysm or dissection surgery and aortic valve surgery between April 1997 and January 2017 were analysed using the patient database. A total of 110 patients with AR who underwent AVr or VSARS due to aortic dissection or aortic aneurysm were included in the study. Results: In the postoperative period, a decrease was observed in AR compared to the preoperative period (P<0.001); there was an increase in postoperative ejection fraction (EF) compared to the preoperative values (P<0.005) and a significant decrease in postoperative left ventricle diameters compared to the preoperative values (P<0.001). Kaplan-Meier analysis revealed one, two, four, and five-year freedom from moderate-severe AR as 95%, 91%, 87%, and 70%, respectively. Freedom from reoperation in one, two, and five years were 97.9%, 93.6%, and 81%, respectively. Eight patients (7.4%) underwent AVr during follow-up. Out of the remaining 100 patients, 13 (12%) had minimum AR, 52 (48%) had 1 st-2 nd degree AR, and 35 (32%) had 2 nd-3 rd degree AR during follow-up. Conclusion: For the purpose of maintaining the native valve tissue, preserving the EF and the left ventricular end-diastolic diameter, valve-sparing surgeries should be preferred for appropriate patients.
